*csupport.txt* C/C++ Support December 28 2011 C/C++ Support *c-support* *csupport* Plugin version 5.17 for Vim version 7.0 and above Fritz Mehner C/C++-IDE for Vim/gVim. It is written to considerably speed up writing code in a consistent style. This is done by inserting complete statements,idioms, code snippets, templates, and comments. Syntax checking, compiling, running a program, running a code checker or a reformatter can be done with a keystroke. 1.

Release Notes /Change Log |csupport-release-notes| How to add this help file to Vim's help |add-local-help| ============================================================================== 1. USAGE WITH GUI (gVim) *csupport-usage-gvim* ============================================================================== If the root menu 'C/C++' is not visible call it with the item "Load C Support" from the standard Tools-menu. The item "Load C Support" can also be used to unload the C/C++-root menu. Nearly all menu entries insert code snippets or comments. All of these are contained within template files and can be changed by the user to meet their requirements (see|csupport-templates|). ------------------------------------------------------------------------------ 1.1 MENU 'Comments' *csupport-comm* ------------------------------------------------------------------------------ 1.1.1 APPEND ALIGNED COMMENTS TO CONSECUTIVE LINES *csupport-comm-aligned* In NORMAL MODE, the menu item 'end-of-line comment' will append a comment to the current line. In VISUAL MODE, this item will append aligned comments to all marked lines. Marking the first 4 lines print_double_array ( double array[], int n, int columns, char* arrayname ) and choosing 'end-of-line com. /**/' will yield. print_double_array ( double array[], /* */ int n, /* */ int columns, /* */ char* arrayname /* */ ) /* */ If one or more lines go beyond the starting column (s.below), the comments will start at the second column after the longest line. The cursor will then be positioned inside the first comment. The default starting column is 49 ( = (multiple of 2,4, or 8) + 1 ). This can be changed by setting a global variable in the file ~/.vimrc , e.g. : let g:C_LineEndCommColDefault = 45 The starting column can also be set by the menu item 'Comments->set end-of-line com. col'. Just position the cursor in an arbitrary column (column number is shown in the Vim status line) and choose this menu item. This setting is buffer related. If the cursor was at the end of a line you will be asked for a column number because this position is most likely not the desired starting column. Your choice will be confirmed. ------------------------------------------------------------------------------ 1.1.2 ADJUST END-OF-LINE COMMENTS *csupport-comm-realign* After some changes end-of-line comments may be no longer aligned: print_double_array ( double array[], /* */ long int n, /* */ unsigned int columns, /* */ char* a_name /* */ ) /* */ Realignment can be achieved with the menu item 'adjust end-of-line com.' In normal mode the comment (if any) in the current line will be aligned to the end-of-line comment column (see above) if possible. In visual mode the comments in the marked block will be aligned: print_double_array ( double array[], /* */ long int n, /* */ unsigned int columns, /* */ char* a_name /* */ ) /* */ The realignment will not be done for comments with nothing else than leading whitespaces. These comments are usually captions: max = other.max; /* the maximum value */ len = other.len; /* the length */ /* ===== the next section ===== */ pos = (x+y+z)/3.0; /* the next position */ After the alignment we have: max = other.max; /* the maximum value */ len = other.len; /* the length */ /* ===== the next section ===== */ pos = (x+y+z)/3.0; /* the next position */ ------------------------------------------------------------------------------ 1.1.3 CODE TO COMMENT *csupport-code-to-comm* The marked block xxxxxxxx xxxxxxxx xxxxxxxx will be changed by the menu item 'code->comment /**/' into the multiline comment (all (partially) marked lines): /* xxxxxxxx * xxxxxxxx * xxxxxxxx */ The marked block will be changed by the menu item 'code->comment //' into the multiline comment //xxxxxxxx //xxxxxxxx //xxxxxxxx The menu items works also for a single line. A single line needs not to be marked. ------------------------------------------------------------------------------ 1.1.4 COMMENT TO CODE *csupport-comm-to-code* If one (or more) complete comment (i.e. all lines belonging to the comment) is marked the item 'comment->code' will uncomment it. If the following lines are marked * printf ("\n"); */ printf ("\n"); // printf ("\n"); // /* * printf ("\n"); */ uncommenting will yield * printf ("\n"); */ printf ("\n"); printf ("\n"); printf ("\n"); The first 2 lines are only a part of a C-comment and remain unchanged. A C-comment can start with /* , /** or /*! . The menu item works also for a single line with a leading // . A single line needs not to be marked. ------------------------------------------------------------------------------ 1.1.5 FRAME COMMENTS, FILE HEADER, ... *csupport-comm-frame* Frame comments, file header comments and function, methods, class descriptions are read as templates from the appropriate files (see |csupport-templates|). There are two file description templates (menu items 'file description (impl.)' and 'file description (header)', see also |csupport-templates|): comment.file-description : files *.c *.cc *.cp *.cxx *.cpp *.CPP *.c++ *.C *.i *.ii comment.file-description-header : everything else with filetype 'c' or 'cpp' The appropriate template will also be included into a new file. The plugin decides on the basis of the file extension. The default is shown above. You can change the list by setting a global variable in '~/.vimrc': au BufRead,BufNewFile *.XYZ set filetype=c let g:C_SourceCodeExtensions = 'XYZ c cc cp cxx cpp CPP c++ C i ii' A new file named 'test.XYZ' will now be considered a C implementation file. ------------------------------------------------------------------------------ 1.1.6 FILE SECTION COMMENTS *csupport-comm-sections* File section comments can be uses to separate typical C- and H-file sections with comments of similar appearance, e.g. /* ##### HEADER FILE INCLUDES ################################################### */ /* ##### MACROS - LOCAL TO THIS SOURCE FILE ################################### */ /* ##### TYPE DEFINITIONS - LOCAL TO THIS SOURCE FILE ######################### */ These section comments can also be inserted using the hotkey \ccs for C/C++ files, or \chs for H-files. These hotkeys will start the command 'CFileSection' or 'HFileSection' on the command line: :CFileSection :HFileSection Now type a to start the selection menu to choose from. ------------------------------------------------------------------------------ 1.1.7 KEYWORD COMMENT, SPECIAL COMMENT *csupport-comm-keyword* Keword comments are end-of-line comments: /* :::: */ Keywords are BUG COMPILER TODO TRICKY WARNING WORKAROUND user-defined-keyword These are preliminary comments to document places where work will be resumed shortly. They are usually not meant for the final documentation. These comments are easily found by searching for the keyword. The keyword comments can also be inserted using the hotkey \ckc . This hotkey starts the command 'KeywordComment' on the command line: :KeywordComment Now type a to start the selection menu to choose from. Special comments are occasionally used to mark special features of a code construct (e.g. a fall through cases in a switch statement, an empty loop): /* EMPTY */ /* NOT REACHED */ /* REMAINS TO BE IMPLEMENTED */ .... The special comments can also be inserted using the hotkey \csc . This hotkey starts the command 'SpecialComment' on the command line: :SpecialComment Now type a to start the selection menu to choose from. ------------------------------------------------------------------------------ 1.1.8 TAGS (PLUGIN) *csupport-comm-tags* The submenu 'tags (plugin)' let you insert the predefined macros from the template system (see|csupport-templates-macros|). In visual mode the marked string will be replaced by the macro. ------------------------------------------------------------------------------ 1.1.9 DATE AND DATE+TIME *csupport-comm-date* The format for 'date' and 'date time' can be defined by the user (see |csupport-templates-date|). In visual mode the marked string will be replaced by the macro (e.g. to update date and time). ------------------------------------------------------------------------------ 1.1.10 C TO C++ COMMENTS AND VICE VERSA *csupport-comm-c-cpp* The menu item '/* xxx */ <-> // xxx' changes a C++ comment into a C comment and a C++ comment into a C comment (toggle). This is done for the current line in normal or insert mode and for a marked area of lines in visual mode. The hotkey \cx does the same. It can be used with a range: 3\cx changes the current line and the next 2 lines. ------------------------------------------------------------------------------ 1.2 MENU 'Statements' *csupport-stat* ------------------------------------------------------------------------------ 1.2.1 NORMAL MODE, INSERT MODE. *csupport-stat-normal-mode* An empty statement will be inserted and properly indented. The item 'if{}' will insert an if-statement: if ( ) { } 1.2.2 VISUAL MODE. *csupport-stat-visual-mode* STATEMENTS WITH BLOCKS AND CASE LABEL. -------------------------------------- The highlighted area xxxxx xxxxx can be surrounded by one of the following statements: +----------------------------+-----------------------------+ | if ( ) | if ( ) | | { | { | | xxxxx | xxxxx | | xxxxx | xxxxx | | } | } | | | else | | | { | | | } | +----------------------------+-----------------------------+ | for ( ; ; ) | while ( ) | | { | { | | xxxxx | xxxxx | | xxxxx | xxxxx | | } | } | +----------------------------+-----------------------------+ | do | | | { | { | | xxxxx | xxxxx | | xxxxx | xxxxx | | } | } | | while ( ); | | +----------------------------+-----------------------------+ | switch ( ) { | | case : | | break; | | | | case : | | break; | | | | case : | | break; | | | | case : | | break; | | | | default: | | break; | | } | +----------------------------+-----------------------------+ The whole statement will be indented after insertion. STATEMENTS WITHOUT BLOCKS. -------------------------- One of the following statements can be inserted: +-------------------------------+--------------------------+ | if ( ) | for ( ; ; ) | +-------------------------------+--------------------------+ | if ( ) | while ( ) | | else | | +-------------------------------+--------------------------+ | case : | | | break; | | +-------------------------------+--------------------------+ ------------------------------------------------------------------------------ 1.3 MENU 'Preprocessor' *csupport-prep* ------------------------------------------------------------------------------ 1.3.1 NORMAL MODE, INSERT MODE. *csupport-prep-normal-mode* The preprocessor statements will be inserted and properly indented. 1.3.2 VISUAL MODE. *csupport-prep-visual-mode* STATEMENTS WITH BLOCKS ---------------------- The highlighted area xxxxx xxxxx can be surrounded by one of the following statements: +----------------------------+-----------------------------+ | #if CONDITION | | xxxxx | | xxxxx | | #else /* ----- #if CONDITION ----- */ | | | | #endif /* ----- #if CONDITION ----- */ | +----------------------------------------------------------+ | #ifdef CONDITION | | xxxxx | | xxxxx | | #else /* ----- #ifdef CONDITION ----- */ | | | | #endif /* ----- #ifdef CONDITION ----- */ | +----------------------------------------------------------+ | #ifndef CONDITION | | xxxxx | | xxxxx | | #else /* ----- #ifndef CONDITION ----- */ | | | | #endif /* ----- #ifndef CONDITION ----- */ | +----------------------------------------------------------+ | #ifndef INC_TEST | | #define INC_TEST | | xxxxx | | xxxxx | | #endif /* ----- #ifndef INC_TEST ----- */ | +----------------------------------------------------------+ | #if 0 /* ----- #if 0 : If0Label_1 ----- */ | | | | #endif /* ----- #if 0 : If0Label_1 ----- */ | +----------------------------------------------------------+ The macro name for an include guard (e.g. INC_TEST above) will be derived as a suggestion from the file name. 1.3.3 BLOCK OUT CODE WITH #if 0 ... #endif *csupport-prep-if0* The menu item #if 0 #endif inserts the lines #if 0 /* ----- #if 0 : If0Label_1 ----- */ #endif /* ----- #if 0 : If0Label_1 ----- */ In visual mode the marked block of lines will be surrounded by these lines. This is usually done to temporarily block out some code. The label names like If0Label_1 are automatically inserted into the comments. The trailing numbers are automatically incremented. These numbers can be changed by the user. The next number will be one above the highest number found in the current buffer. A corresponding label can be found by searching with the vim star command (*). All labels can be found with a global search like :g/If0Label_/ or :g/If0Label_\d\+/. All corresponding lines can be deleted with :g/If0Label_/d . REMOVE THE ENCLOSING #if 0 ... #endif -CONSTRUCT. The menu item 'remove #if #endif' removes such a construct if the cursor is in the middle of such a section or on one of the two enclosing lines. Nested constructs will be untouched. 1.3.4 EX-COMMANDS *csupport-prep-ex* There are 4 additional Ex command which can be used to insert include statements: Ex command hotkey includes ------------------------------------------------------------------------- :IncludeStdLibrary \ps C standard library :IncludeC99Library \pc C99 library :IncludeCppLibrary \+ps C++ standard library :IncludeCppCLibrary \+pc C standard library ( #include ) Type :Inc and choose one of the commands. Now type an additional space and a to show the whole list list or type a space and a few leading characters to reduce this list. ------------------------------------------------------------------------------ 1.4 MENU 'Idioms' *csupport-idioms* ------------------------------------------------------------------------------ 1.4.1 Item 'function' *csupport-idioms-function* NORMAL MODE, INSERT MODE: The name of the function is asked for and the following lines (for function name "f") will be inserted: void f ( ) { return ; } /* ---------- end of function f ---------- */ VISUAL MODE: Main or [static] function: the highlighted lines will go inside the new function or main. for-loops: the highlighted lines will be set in braces. 1.4.2 for-loop control *csupport-idioms-for-loop* The menu items 'for( x=0; ... )' and 'for( x=n-1; ... )' can be used to write the control statement for a for-loop counting upward or downward. These items start an input dialog [TYPE (expand)] VARIABLE [START [END [INCR.]]] : asking for at least the name of the loop variable. The other parameters are optional. The type is restricted to the following integral data types: char int long long int long long long long int short short int size_t unsigned unsigned char unsigned int unsigned long unsigned long int unsigned long long unsigned long long int unsigned short unsigned short int One of these types can be specified by typing it completely or by typing zero or more characters of its name and completing them to the full name by using the tab key (tab completion). If the start of the type name is ambiguous (e.g. 'uns') a list of completion candidates is provided to choose from. 1.4.3 Item 'open input file' *csupport-idioms-input* The item 'open input file' will create the statements to open and close an input file (e.g. with the file pointer 'infile'). 1.4.4 Item 'open output file' *csupport-idioms-output* The item 'open output file' will create the statements to open and close an output file (e.g. with the file pointer 'outfile'). ------------------------------------------------------------------------------ 1.5 MENU 'Snippets' *csupport-snippets* ------------------------------------------------------------------------------ 1.5.1 CODE SNIPPETS Code snippets are pieces of code which are kept in separate files in a special directory (e.g. a few lines of code or a complete template for a Makefile). File names are used to identify the snippets. The snippet directory will be created during the installation ( $HOME/.vim/codesnippets-c is the default). Snippets are managed with the 3 items C/C++ -> Snippets -> read code snippet C/C++ -> Snippets -> write code snippet C/C++ -> Snippets -> edit code snippet from the Snippets submenu. CREATING A NEW SNIPPET When nothing is marked, "write code snippet" will write the whole buffer to a snippet file, otherwise the marked area will be written to a file. INSERT A SNIPPET Select the appropriate file from the snippet directory ("read code snippet"). The inserted lines will be indented. EDIT A SNIPPET This is a normal edit. INDENTATION / NO INDENTATION Code snippets are normally indented after insertion. To suppress indentation add the file extension "ni" or "noindent" to the snippet file name, e.g. parameter_handling.c.noindent Snippet browser --------------- Under a GUI a file requester will be put up. Without GUI the filename will be read from the command line. You can change this behavior by setting a global variable in your ~/.vimrc : let g:C_GuiSnippetBrowser = 'commandline' The default value is 'gui'. 1.5.2 PICKING UP PROTOTYPES *csupport-proto* PICK UP FUNCTION PROTOTYPES (key mappings \np, \nf). To make a prototype from a function head mark the function head and choose 'Snippets -> pick up funct. prototype'. From the first six lines of void print_double_array ( double array[], /* array to print */ int n, /* number of elements to print */ int columns, /* number of elements per column */ char* arrayname /* array name */ ) { ... } /* ---------- end of function print_double_array ---------- */ the prototype void print_double_array ( double array[], int n, int columns, char* arrayname ); is produced and put in an internal buffer. - Leading and trailing whitespaces are removed. - All inner whitespaces are squeezed. - All comments will be discarded. - Trailing parts of the function body (e.g a '{' ) will also be removed. - The class name and the scope resolution operator will be removed (C++ method implementations). Further prototypes can be picked up and gathered in the buffer. PICK UP METHOD PROTOTYPES (key mapping \nm). For C++ methods the menu item 'Snippets -> pick up method prototype' should be used. Namespace names and class names will be removed (exception: 'std::' ). The first two lines of std::string ROBOT::Robot::get_name ( void ) { return type_name; } /* ----- end of method Robot::get_name ----- */ result in the prototype std::string get_name ( void ); The 3 lines template const Stack& Stack::operator = ( const Stack &other ) result in the prototype const Stack& operator = ( const Stack &other ); Folding may help picking up prototypes (see |csupport-folding|). INSERT PROTOTYPES With 'Snippets -> insert prototype(s)' all picked up prototypes currently in the buffer will be inserted below the cursor. The prototype buffer will be cleared after insertion. DISCARD PROTOTYPES The prototype buffer can be cleared with 'Snippets -> clear prototype(s)' . SHOW PROTOTYPES The list of gathered prototypes can be shown with 'Snippets -> show prototype(s)'. The number and the filename are shown, e.g. (1) matrix.c # double** calloc_double_matrix ( int rows, int columns ); (2) matrix.c # void free_double_matrix ( double **m ); (3) foomain.c # void foo ( ); REMARK. Generating prototypes this way is nice in a small project. You may want to use an extractor like cextract or something else. 1.5.3 Code Templates *csupport-templates-menu* --------------------- Nearly all menu entries insert code snippets or comments. All these stuff is taken from template files and can be changed by the user to meet his requirements (see|csupport-templates|on how to use the template system). The menu item 'edit local templates' opens the main template file in a local plugin installation. This is usually the file '~/.vim/c-support/templates/Templates'. There may be dependent files loaded from the main file. Now change whatever file you want, save it, and click on the menu item 'reread templates' to read in the file(s) and to rebuild the internal representation of the templates. The menu item 'edit global templates' opens the main template file in a system-wide plugin installation (see |csupport-system-wide|). This is usually the file '$VIM./vimfiles/c-support/templates/Templates'. Template browser ---------------- Under a GUI a file requester will be put up. Without GUI the filename will be read from the command line. You can change this behavior by setting a global variable in your ~/.vimrc : let g:C_GuiTemplateBrowser = 'explorer' The default value is 'gui'. 'explorer' will start the file explorer (see help|:Explore|). To use the commandline asign 'commandline'. ------------------------------------------------------------------------------ 1.6 MENU 'C++' *csupport-c++* ------------------------------------------------------------------------------ 1.6.1 NORMAL MODE, INSERT MODE. *csupport-c++-normal-mode* An empty statement will be inserted and in some cases properly indented. The item 'try .. catch' will insert the following lines: try { } catch ( const &ExceptObj ) { // handle exception: } catch (...) { // handle exception: unspecified } The cursor will go into the try block. 1.6.2 VISUAL MODE. *csupport-c++-visual-mode* The highlighted area can be surrounded by one of the following statements: try - catch catch catch(...) namespace { } extern "C" { } The whole statement will be indented after insertion. 1.6.3 METHOD IMPLEMENTATION *csupport-c++-method-impl* The menu item 'method implement.' asks for a method name. If this item is called the first time you will see just an scope resolution operator. If you specify the scope this is used the next time you call this item. If you use one of the menu items to generate a class (see |csupport-templates|) the scope will be extracted and used for the next method. 1.6.4 EX COMMANDS *csupport-c++-ex* There are 4 additional Ex command which can be used to insert include statements. Please see |csupport-prep-ex|. ------------------------------------------------------------------------------ 1.7 MENU 'Run' *csupport-run* ------------------------------------------------------------------------------ 1.7.1 MINIMAL MAKE FUNCTIONALITY *csupport-run-buffer* The 'Run' menu provides a minimal make functionality for single file projects (e.g. in education) : SAVE AND COMPILE 'save and compile' saves the buffer and run the compiler with the given options (see |csupport-custom-glob-vars|). An error window will be opened if the compiler reports errors and/or warnings. Quickfix commands can now be used to jump to an error location. Consider using maps like map :cprevious map :cnext in your ~/.vimrc file to jump over the error locations and make navigation easier. The error list and the error locations in your source buffer will be synchronized. The filename extension for an object file can be set in ~.vimrc : let g:C_ObjExtension = '.obj' The default is '.o' ('.obj' for Windows). LINK 'link' makes an executable from the current buffer. If the buffer is not saved, or no object is available or the object is older then the source step 'save and compile' is executed first. The linkging will only be tried if the current buffer contains a main function. The behavior of the compiler / linker is determined by the options assigned to the variables described in |csupport-custom-glob-vars| (4.group). RUN 'run' runs the executable with the same name as the current buffer. If the buffer is not saved, or no executable is available or the executable is older then the source steps 'save and compile' and 'link' are executed first. The filename extension for an executable can be set in ~.vimrc : let g:C_ExeExtension = '.exe' The default is the empty string. 1.7.2 COMMAND LINE ARGUMENTS *csupport-run-cmdline-args* The item 'command line arguments' calls an input dialog which asks for command line arguments. These arguments are forwarded to the program which is run by the 'run' item. The arguments are kept until you change them. For the first and only the first argument file name expansion will work (use the Tab-key). Only the first string of the input can be expanded due to a restriction of the Vim input function. To expand two or more filenames specify them in reverse order: type the first characters of the last filename and expand them. Go to the start of the input and type the beginning of the last but one filename and expand it. The arguments belong to the current buffer (that is, each buffer can have its own arguments). If the buffer gets a new name with "save as" the arguments will now belong to the buffer with the new name. The command line arguments can be followed by pipes and redirections: 11 22 | sort -rn | head -10 > out Caveat: If you look for the current arguments by calling this menu item again be sure to leave it with a CR (not Esc !). Due to a limitation of an internal Vim function CR will keep the arguments, Esc will discard them. 1.7.3 RUN make *csupport-run-make* The item 'make' runs the external make program. An error window will be opened if the compiler or linker reports errors or warnings during the make process. Quickfix commands can now be used to jump to an error location. Make looks for a makefile in the current directory (but see below). When inside a makefile the hotkeys \rm, \rmc, \rcm, and \rma are working (see |csupport-usage-vim|). The snippets collection contains a sample makefile which can easily adepted for small projcts. 1.7.4 Choose Makefile *csupport-choose-makefile* The menu item 'choose makefile' let you specify a makefile in another directory than the current one. Now this makefile will be used instead of the one in the current directory (if any). Make is started from the directory in which the makefile is contained. The working directory for the current buffer will not be changed. 1.7.5 EXECUTABLE TO RUN *csupport-run-make-run* The item 'executable to run' asks for the name of the executable built by make. If the name given is nonempty this executable will be run by the menu item 'run' (\rr, C-F9). To return to the default behavior (see |csupport-run-buffer|) remove the name with the another 'executable to run'. 1.7.6 RUN make clean *csupport-run-make-clean* The item 'make' runs the external make program with the standard target 'clean'. If an alternate makefile has been chosen (see|csupport-choose-makefile|), this one will be run from the directory in which the makefile is contained. 1.7.7 COMMAND LINE ARGUMENTS FOR make *csupport-run-make-args* The item 'command line arguments for make' calls an input dialog which asks for command line arguments for make. These arguments are forwarded to make when called by the menu item 'make'. For the first and only the first argument the file name expansion will work (use the Tab-key). 1.7.8 SPLINT *csupport-run-splint* Splint is a tool for statically checking C programs (see http://www.splint.org). Of course it has to be installed in order to be used within Vim. The menu item 'Run->splint' will run the current buffer through splint. An error window will be opened if splint has something to complain about. Quickfix commands can now be used to jump to an error location. For easier navigation see tip under 'SAVE AND COMPILE' |csupport-run-buffer|. Splint has many options. Presumably the best way is to keep the options in an option file (~/.splintrc). For a quick try you can use the menu item 'Run->cmd. line arg. for splint' to specify some buffer related options. When vim is started this plugin will check whether splint is executable. If not, the menu item will *NOT' be visible. 1.7.9 CODECHECK *csupport-run-codecheck* CodeCheck (TM) is a commercial code analyzing tool produced by Abraxas Software, Inc. (www.abraxas-software.com). Of course it has to be installed in order to be used within Vim. The menu item 'Run->CodeCheck' will run the current buffer through CodeCheck. An error window will be opened if CodeCheck has something to complain about. Quickfix commands can now be used to jump to an error location. For easier navigation see tip under 'SAVE AND COMPILE' |csupport-run-buffer|. CodeCheck has many options. For a quick try you can use the menu item 'Run->cmd. line arg. for CodeCheck' to specify some buffer related options. CodeCheck will be run with default options (see |csupport-custom-glob-vars|). The default options can be overwritten by placing a global variable in ~/.vimrc , e.g. let g:C_CodeCheckOptions = "-K13 -Rmeyers" The default name for the executable is 'check'. There are other names in use on different platforms. The name can be changed by placing a global variable in ~/.vimrc , e.g. let g:C_CodeCheckExeName = "chknt.exe" When vim is started this plugin will check whether CodeCheck is executable. If not, the menu item will *NOT' be visible. 1.7.10 INDENT *csupport-run-indent* The formatter 'indent' can be run over the whole buffer. Before formatting a buffer this buffer will be saved to disk and you will be asked for a confirmation. Indent has many options. These are kept in the file '.indent.pro' in your home directory. See the indent manual for more information. 1.7.11 HARDCOPY *csupport-run-hardcopy* Generates a PostScript file from the whole buffer or from a marked region. On a Windows system a printer dialog is displayed. The hardcopy goes to the current working directory. If the buffer contains documentation or other material from non-writable directories the hardcopy goes to the HOME directory. The output destination will be shown in a message. The print header contains date and time for the current locale. The definition used is let s:C_Printheader = "%<%f%h%m%< %=%{strftime('%x %X')} Page %N" The current locale can be overwritten by changing the language, e.g. :language C or by setting a global variable in the file ~/.vimrc , e.g. : let g:C_Printheader = "%<%f%h%m%< %=%{strftime('%x %X')} SEITE %N" See :h printheader and :h strftime() for more details. 1.7.12 REBUILD TEMPLATES *csupport-run-templates* After editing one or more template files a click on this item rereads the template files and rebuilds all templates. 1.7.13 XTERM SIZE *csupport-run-xterm* The size of the xterm used for running a program (below) can be set by this menu item. The default is 80 columns with 24 lines. This feature is not available under Windows. 1.7.14 OUTPUT REDIRECTION *csupport-run-output* Running a program can be done in one of three ways: (1) Run the program from the gVim command line. This is for interactive programs with little input and output. (2) Run the program and direct the output into a window with name "C-Output". The buffer and its content will disappear when the window is closed and reused otherwise. This is for non-interactive programs with little to very much output. You have unlimited line length, regex search, navigation, ... The tabstop value will be set to 8 for "C-Output". (3) Run the program in an xterm. The output method can be chosen from the menu item 'Run->output: ...'. This menu has three states: output: VIM->buffer->xterm output: BUFFER->xterm->vim output: XTERM->vim->buffer The first (uppercase) item shows the current method. The default is 'vim'. This can be changed by setting the variable g:C_OutputGvim to another value. Possible values are 'vim', 'buffer' and 'xterm' . The xterm defaults can be set in ~/.vimrc by the variable g:C_XtermDefaults . The default is "-fa courier -fs 12 -geometry 80x24" : font name : -fa courier font size : -fs 12 terminal size : -geometry 80x24 See 'xterm -help' for more options. Xterms are not available under Windows. ------------------------------------------------------------------------------ 1.8 'help' *csupport-help* ------------------------------------------------------------------------------ Plugin help ----------- The root menu item 'help (plugin)' shows this plugin help in a help window. The help tags must have been generated with :helptags ~/.vim/doc The hotkey is \hp (for "help plugin"). Displaying a manual ------------------- The root menu item 'show manual' shows the manual for the word under the cursor. If there is more than one manual a selection list will be presented. If there is no word under the cursor you can type in a name. An interface to the on-line reference manuals must be installed (usually man(1) for Linux/Unix, see|csupport-custom-glob-vars|). The hotkey is \hm (for "help manual"). ============================================================================== 2. USAGE WITHOUT GUI (Vim) *csupport-usage-vim* ============================================================================== The frequently used constructs can be inserted with key mappings. The mappings are also described in the document c-hot-keys.pdf (reference card, part of this package). Hint: Typing speed matters. The combination of a leader ('\') and the following character(s) will only be recognized for a short time. Some mappings can be used with range (of lines). In normal mode \cl appends a end-of-line comment to the current line, whereas 4\cl appends end-of-line comments to the 4 lines starting with the current line.

The 'line end comment' command is now defined as ',cl'. This setting will be used as a so called local leader and influences only files with filetype 'c' and 'cpp'. ============================================================================== 3. HOTKEYS *csupport-hotkeys* ============================================================================== The following hotkeys are defined in normal, visual and insert mode: F9 compile and link Alt-F9 write buffer and compile Ctrl-F9 run executable Shift-F9 set command line arguments Shift-F2 switch between source files and header files The hotkeys are defined in the file type plugin c.vim. All hotkeys from the non-GUI mode also work for gVim (see |csupport-usage-vim|). Shift-F2 can be used to switch between source files and header files if the plugin a.vim (http://vim.sourceforge.net/scripts/script.php?script_id=31) is present. To suppress the creation of a new header file when switching from a source file the file ~/.vimrc should contain a line let g:alternateNoDefaultAlternate = 1 A header file will only be opened if it already exists. The Shift-key is dead when you are working with Vim in a console terminal (non-Gui). You could add noremap \a :A inoremap \a :A to get a hot key for this case. ============================================================================== 4. CUSTOMIZATION *csupport-custom* ============================================================================== ------------------------------------------------------------------------------ 4.1 GLOBAL VARIABLES *csupport-custom-glob-vars* ------------------------------------------------------------------------------ Several global variables are checked by the script to customize it: ---------------------------------------------------------------------------- GLOBAL VARIABLE DEFAULT VALUE TAG (see below) ---------------------------------------------------------------------------- g:C_GlobalTemplateFile plugin_dir.'c-support/templates/Templates' g:C_LocalTemplateFile $HOME.'/.vim/c-support/templates/Templates' g:C_TemplateOverwrittenMsg 'yes' g:C_Ctrl_j 'on' g:C_CodeSnippets plugin_dir.'/c-support/codesnippets/' g:C_Dictionary_File '' g:C_LoadMenus 'yes' g:C_MenuHeader 'yes' g:C_OutputGvim 'vim' g:C_Root '&C\/C\+\+.' g:C_XtermDefaults '-fa courier -fs 12 -geometry 80x24' g:C_Printheader "%<%f%h%m%< %=%{strftime('%x %X')} Page %N" g:C_MapLeader '\' g:C_GuiSnippetBrowser 'gui' g:C_GuiTemplateBrowser 'gui' Linux/UNIX: g:C_ObjExtension '.o' g:C_ExeExtension '' g:C_CCompiler 'gcc' g:C_CplusCompiler 'g++' g:C_Man 'man' Windows: g:C_ObjExtension '.obj' g:C_ExeExtension '.exe' g:C_CCompiler 'gcc.exe' g:C_CplusCompiler 'g++.exe' g:C_Man 'man.exe' g:C_VimCompilerName gcc g:C_CFlags '-Wall -g -O0 -c' g:C_LFlags '-Wall -g -O0' g:C_Libs '-lm' g:C_LineEndCommColDefault 49 g:C_CExtension 'c' g:C_TypeOfH 'cpp' g:C_SourceCodeExtensions 'c cc cp cxx cpp CPP c++ C i ii' g:C_CodeCheckExeName 'check' g:C_CodeCheckOptions '-K13' The variable plugin_dir will automatically be set to one of the following values: $HOME.'/.vim/' for Linux/Unix $VIM.'/vimfiles/' for Windows ---------------------------------------------------------------------------- 1. group: g:C_GlobalTemplateFile : Sets the master template file (see|csupport-templates|) g:C_LocalTemplateFile : Sets the local template file (see|csupport-templates|) g:C_TemplateOverwrittenMsg : message if template is overwritten g:C_Ctrl_j : hotkey Ctrl-j 'on'/'off' (see|csupport-Ctrl-j|) 2. group: g:C_CodeSnippets : The name of the code snippet directory (see |csupport-snippets|). g:C_Dictionary_File : The name(s) of the dictionary file(s) used for word completion (see also |csupport-dictionary|) g:C_LoadMenus : Load menus and mappings ("yes", "no") at startup. g:C_MenuHeader : Switch the submenu header on/off. g:C_OutputGvim : when program is running output goes to the vim command line ("vim"), to a buffer ("buffer") or to an xterm ("xterm"). g:C_Root : The name of the root menu entry of this plugin (see |csupport-custom-root|). g:C_XtermDefaults : the xterm defaults g:C_Printheader : hardcopy: definition of the page header g:C_MapLeader : the map leader for hotkeys (see|csupport-usage-vim|) g:C_GuiSnippetBrowser : code snippet browser: 'gui', 'commandline' g:C_GuiTemplateBrowser : code template browser: 'gui', 'explorer', 'commandline' 3. group: g:C_CExtension : Extension of C files. Everything else is C++. g:C_TypeOfH : filetype of header files with extension 'h' (c,cpp) g:C_SourceCodeExtensions : filename extensions for C/C++ implementation files g:C_CCompiler : The name of the C compiler. g:C_CplusCompiler : The name of the C++ compiler. g:C_VimCompilerName : the compiler name used by :compiler g:C_Man : The name of the man utility. g:C_CFlags : Compiler flags used for a compilation. g:C_LFlags : Compiler flags used for linkage. g:C_Libs : Libraries to link with. g:C_ObjExtension : C/C+ file extension for objects (leading point required if not empty) g:C_ExeExtension : C/C+ file extension for executables (leading point required if not empty) g:C_LineEndCommColDefault : Default starting column for end-of-line comments. g:C_CodeCheckExeName : The name of the CodeCheck (TM) executable (the default is 'check') g:C_CodeCheckOptions : Default options for CodeCheck (TM) (see |csupport-run-codecheck|). To override the default add appropriate assignments to ~/.vimrc . ------------------------------------------------------------------------------ 4.2 THE ROOT MENU *csupport-custom-root* ------------------------------------------------------------------------------ The variable g:C_Root, if set (in '.vimrc' or in '.gvimrc'), gives the name of the single gVim root menu entry in which the C/C++ submenus will be put. The default is '&C\/C\+\+.' '' Note the terminating dot. If you want to set the plugin root menu into another menu, e.g. 'Plugin', this is done by the following line in '.vimrc' let g:C_Root = '&Plugin.&C\/C\+\+.' ------------------------------------------------------------------------------ 4.3 SYSTEM-WIDE INSTALLATION *csupport-system-wide* ------------------------------------------------------------------------------ A system-wide installation (one installation for all users) is done as follows. As *** SUPERUSER *** : (1) Find the Vim installation directory. The Vim Ex command ':echo $VIM' gives '/usr/local/share/vim' or something like that. Beyond this directory you will find the Vim installation, e.g. in '/usr/local/share/vim/vim73' if Vim version 7.3 has been installed (Windows: 'C:\Program Files\Vim'). (2) Create a new subdirectory 'vimfiles', e.g. '/usr/local/share/vim/vimfiles' (Windows: 'C:\Program Files\Vim\vimfiles'). (3) Install C/C++ Support Copy the archive cvim.zip to this new directory and unpack it: unzip cvim.zip (4) Generate the help tags: :helptags $VIM/vimfiles/doc SPECIAL CASES. Some Linux distributions use non-standard names for Vim directories. SUSE has a directory '/usr/share/vim/site' to put plugins in. These directories will not be found automatically. After installing the plugin below '/usr/share/vim/site' the use of the templates will be enabled by the following line in '~/.vimrc': let g:C_GlobalTemplateFile = '/usr/share/vim/site/c-support/templates/Templates' As *** USER *** : Create your private snippet directory: mkdir --parents ~/.vim/c-support/codesnippets You may want to copy the snippets coming with this plugin (in $VIM/vimfiles/c-support/codesnippets) into the new directory or to set a link to the global directory. Create your private template directory: mkdir --parents ~/.vim/c-support/templates Create a private template file 'Templates' (compulsory) in this directory to overwrite some macros, e.g. *|AUTHOR|* = your name *|AUTHORREF|* = ... *|EMAIL|* = ... *|COMPANY|* = ... *|COPYRIGHT|* = ... You can also have local templates which overwrite the global ones. To suppress the messages in this case set a global variable in '~/.vimrc' (Windows: '~\_vimrc') : let g:C_TemplateOverwrittenMsg= 'no' The default is 'yes'. ============================================================================== 5. TEMPLATE FILES AND TAGS *csupport-templates* ============================================================================== ------------------------------------------------------------------------------ 5.1 TEMPLATE FILES *csupport-templates-files* ------------------------------------------------------------------------------ Nearly all menu entries insert code snippets or comments. All of these are contained within template files and can be changed by the user to meet their requirements. The master template file is '$HOME/.vim/c-support/templates/Templates' for a user installation and '$VIM/vimfiles/c-support/templates/Templates' for a system-wide installation (see|csupport-system-wide|). The master template file starts with a macro section followed by templates for single menu items or better by including other template files grouping the templates according to the menu structure of this plugin. The master file could look like this: $ $ ============================================================= $ ========== USER MACROS ====================================== $ ============================================================= $ *|AUTHOR|* = Dr. Fritz Mehner *|AUTHORREF|* = mn *|EMAIL|* = mehner@fh-swf.de *|COMPANY|* = FH Südwestfalen, Iserlohn *|COPYRIGHT|* = Copyright (c)*|YEAR|,|AUTHOR|* $ $ ============================================================= $ ========== FILE INCLUDES ==================================== $ ============================================================= $ *|includefile|* = c.comments.template *|includefile|* = c.cpp.template *|includefile|* = c.idioms.template *|includefile|* = c.preprocessor.template *|includefile|* = c.statements.template Lines starting with a dollar sign are comments. The section starting with *|AUTHOR|* assigns values to predefined tags (see|csupport-templates-macros|) to personalize some templates. Other predefined tags with given default values can be used (e.g. *|YEAR|* ). User defined tags are possible. They have the following syntax: *|macroname|* = replacement A macroname starts with a letter (uppercase or lowercase) followed by zero or more letters, digits or underscores. ------------------------------------------------------------------------------ 5.2 MACROS *csupport-templates-macros* ------------------------------------------------------------------------------ The following macro names are predefined. The first group is used to personalize templates. ---------------------------------------------------------------------------- PREDEFINED MACROS DEFAULT VALUE ---------------------------------------------------------------------------- *|AUTHOR|* "" *|AUTHORREF|* "" *|EMAIL|* "" *|COMPANY|* "" *|PROJECT|* "" *|COPYRIGHTHOLDER|* "" *|STYLE|* "" *|includefile|* "" *|BASENAME|* filename without path and suffix *|DATE|* the preferred date representation for the current locale without the time *|FILENAME|* filename without path *|PATH|* path without filename *|SUFFIX|* filename suffix *|TIME|* the preferred time representation for the current locale without the date and the time zone or name or abbreviation *|YEAR|* the year as a decimal number including the century The macro *|includefile|* can be used to include an additional template file. A file will be included only once. Commenting and uncommenting include macros is a simple way to switch between several sets of templates (see also |csupport-run-templates|). Overwriting existing macros and templates is possible. ---------------------------------------------------------------------------- PREDEFINED TAGS ---------------------------------------------------------------------------- ,{CURSOR} The cursor position after insertion of a template <+text+>,<-text->, Jump targets in templates. Jump with Ctrl-j. {+text+},{-text-} See |csupport-templates-jump|. The split point when inserting in visual mode (see|csupport-templates-definition|) A dependent template file can start with its own macro section. There is no need to have all user defined macros in the master file. When the first template definition is found (see below) macro definitions are no longer recognized. Use the tag variant with curly braces if the indentation of the following line is wrong after template insertion. ------------------------------------------------------------------------------ 5.2.1 USER DEFINED FORMATS FOR DATE AND TIME *csupport-templates-date* ------------------------------------------------------------------------------ The format for *|DATE|* ,*|TIME|* , and*|YEAR|* can be set by the user. The defaults are *|DATE|* '%x' *|TIME|* '%X' *|YEAR|* '%Y' See the manual page of the C function strftime() for the format. The accepted format depends on your system, thus this is not portable! The maximum length of the result is 80 characters. User defined formats can be set using the following global variables in ~/.vimrc , e.g. let g:C_FormatDate = '%D' let g:C_FormatTime = '%H:%M' let g:C_FormatYear = 'year %Y' ------------------------------------------------------------------------------ 5.3 TEMPLATES *csupport-templates-names* ------------------------------------------------------------------------------ 5.3.1 Template names The template behind a menu entry is identified by a given name. The first part of the name identifies the menu, the second part identifies the item. The modes are also hard coded (see|csupport-templates-definition|for the use of ). TEMPLATE NAME MODES -------------------------------------------------------------------------- comment.class normal comment.end-of-line-comment normal comment.file-description normal comment.file-description-header normal comment.file-section-cpp-class-defs normal comment.file-section-cpp-class-implementations-exported normal comment.file-section-cpp-class-implementations-local normal comment.file-section-cpp-data-types normal comment.file-section-cpp-function-defs-exported normal comment.file-section-cpp-function-defs-local normal comment.file-section-cpp-header-includes normal comment.file-section-cpp-local-variables normal comment.file-section-cpp-macros normal comment.file-section-cpp-prototypes normal comment.file-section-cpp-typedefs normal comment.file-section-hpp-exported-class-defs normal comment.file-section-hpp-exported-data-types normal comment.file-section-hpp-exported-function-declarations normal comment.file-section-hpp-exported-typedefs normal comment.file-section-hpp-exported-variables normal comment.file-section-hpp-header-includes normal comment.file-section-hpp-macros normal comment.frame normal comment.function normal comment.keyword-bug normal comment.keyword-compiler normal comment.keyword-keyword normal comment.keyword-todo normal comment.keyword-tricky normal comment.keyword-warning normal comment.keyword-workaround normal comment.method normal comment.special-constant-type-is-long normal comment.special-constant-type-is-unsigned-long normal comment.special-constant-type-is-unsigned normal comment.special-empty normal comment.special-fall-through normal comment.special-implicit-type-conversion normal comment.special-no-return normal comment.special-not-reached normal comment.special-remains-to-be-implemented normal cpp.accessor-implementation normal cpp.catch normal, visual cpp.catch-points normal, visual cpp.cin normal cpp.class-definition normal cpp.class-implementation normal cpp.class-using-new-definition normal cpp.class-using-new-implementation normal cpp.cout-operator normal cpp.cout normal cpp.error-class normal cpp.extern normal, visual cpp.method-implementation normal cpp.namespace-block normal, visual cpp.namespace normal cpp.namespace-std normal cpp.open-input-file normal cpp.open-output-file normal cpp.operator-in normal cpp.operator-out normal cpp.output-manipulator-boolalpha normal cpp.output-manipulator-dec normal cpp.output-manipulator-endl normal cpp.output-manipulator-fixed normal cpp.output-manipulator-flush normal cpp.output-manipulator-hex normal cpp.output-manipulator-internal normal cpp.output-manipulator-left normal cpp.output-manipulator-oct normal cpp.output-manipulator-right normal cpp.output-manipulator-scientific normal cpp.output-manipulator-setbase normal cpp.output-manipulator-setfill normal cpp.output-manipulator-setiosflag normal cpp.output-manipulator-setprecision normal cpp.output-manipulator-setw normal cpp.output-manipulator-showbase normal cpp.output-manipulator-showpoint normal cpp.output-manipulator-showpos normal cpp.output-manipulator-uppercase normal cpp.rtti-const-cast normal cpp.rtti-dynamic-cast normal cpp.rtti-reinterpret-cast normal cpp.rtti-static-cast normal cpp.rtti-typeid normal cpp.template-accessor-implementation normal cpp.template-class-definition normal cpp.template-class-implementation normal cpp.template-class-using-new-definition normal cpp.template-class-using-new-implementation normal cpp.template-function normal cpp.template-method-implementation normal cpp.try-catch normal, visual idioms.assert normal idioms.calloc normal idioms.enum normal, visual idioms.fprintf normal idioms.fscanf normal idioms.function normal, visual idioms.function-static normal, visual idioms.main normal, visual idioms.malloc normal idioms.open-input-file normal idioms.open-output-file normal idioms.printf normal idioms.scanf normal idioms.sizeof normal idioms.struct normal, visual idioms.union normal, visual preprocessor.define normal preprocessor.ifdef-else-endif normal, visual preprocessor.if-else-endif normal, visual preprocessor.ifndef-def-endif normal, visual preprocessor.ifndef-else-endif normal, visual preprocessor.include-global normal preprocessor.include-local normal preprocessor.undefine normal statements.block normal, visual statements.case normal statements.do-while normal, visual statements.for-block normal statements.for normal statements.if-block-else normal, visual statements.if-block normal, visual statements.if-else normal, visual statements.if normal statements.switch normal, visual statements.while-block normal, visual statements.while normal 5.3.2 Template definition *csupport-templates-definition* A template definition starts with a template head line with the following syntax: == templatename == [ position == ] The templatename is one of the above template identifiers. The position attribute is optional. Possible attribute values are: above insert the template before the current line append append the template to the current line below insert the template below the current line insert insert the template at the cursor position start insert the template before the first line of the buffer An example: == comment.function == /* * === FUNCTION ======================================================= * Name: * Description: * ====================================================================== */ The definition of a template ends at the next head line or at the end of the file. Templates for the visual mode can use . The text before will than be inserted above the marked area, the text after will be inserted behind the marked area. An example: == statements.if-block-else == if ( ) { } else { } If applied to the marked block xxxxxxxxxxx xxxxxxxxxxx this template yields if ( ) { xxxxxxxxxxx xxxxxxxxxxx } else { } The templates with a visual mode are shown in the table under |csupport-templates-names|. 5.3.3 Template expansion *csupport-templates-expansion* There are additional ways to control the expansion of a template. USER INPUT ---------- If the usage of a yet undefined user macro starts with a question mark the user will be asked for the replacement first, e.g. with the following template == idioms.function == void *|?FUNCTION_NAME|* ( ) { return ; } /* ----- end of function*|FUNCTION_NAME|* ----- */ The user can specify the function name which then will be applied twice. If the macro was already in use the old value will be suggested as default. MACRO MANIPULATION ------------------ A macro expansion can be controlled by the following attributes :l change macro text to lowercase :u change macro text to uppercase :c capitalize macro text :L legalize name The include guard template is an example for the use of ':L' : == preprocessor.ifndef-def-endif == #ifndef *|?BASENAME:L|_INC* #define *|BASENAME|_INC* #endif // ----- #ifndef*|BASENAME|_INC* ----- The base name of the file shall be used as part of the include guard name. The predefined macro*|BASENAME|* is used to ask for this part because this macro has already a defined value. That value can accepted or replaced by the user. For the filename 'test test++test.h' the legalized base name 'TEST_TEST_TEST' will be suggested. Legalization means: - replace all whitespaces by underscores - replace all non-word characters by underscores - replace '+' and '-' by underscore 5.3.4 The macros <+text+> etc. *csupport-templates-jump* There are four macro types which can be used as jump targets in templates: <+text+> Can be jumped to by hitting Ctrl-j. {+text+} Same as <+text+>. Used in cases where indentation gives unwanted results with the first one. <-text-> Same as the two above. Will be removed if the template is used {-text-} in visual mode. The text inside the brackets is userdefined and can be empty. The text can be composed from letters (uppercase and lowercase), digits, underscores and blanks. After the insertion of an template these jump targets will be highlighted. 5.3.5 Command Ctrl-j *csupport-Ctrl-j* Use the command Ctrl-j to jump to the next target. The target will be removed and the mode will switched to insertion. Ctrl-j works in normal and in insert mode. The template for a function can be written as follows: == idioms.function == void |?FUNCTION_NAME| ( <+argument list+> ) { return <+return value+>; } /* ----- end of function |FUNCTION_NAME| ----- */ The cursor will be set behind 'void'. You can remove 'void' easily with Ctrl-w (delete word before cursor) and insert a new type. A Ctrl-j leads you to the argument list. The target disappears and you can type on. When the function body is written a final Ctrl-j brings you to the return statement. The following example shows the usage of the type {-text-}. The idiom for the opening of a file marks the line before the file is closed. This is also the line where the template will be split to surround a marked area. In this case (visual mode) the target is not needed and therefore removed (minus signs as mnemonic). In normal and insert mode the target is meaningful and will be therefore be present. The form <-...-> would result in a wrong indentation of the file close statement. The brace type will be handled as a block and the indentation will be correct. == cpp.open-input-file == char *ifs_file_name = ""; /* input file name */ ifstream ifs; /* create ifstream object */ ifs.open (ifs_file_name); /* open ifstream */ if (!ifs) { cerr << "\nERROR : failed to open input file " << ifs_file_name << endl; exit (EXIT_FAILURE); } {-continue here-} ifs.close (); /* close ifstream */ Extra feature of Ctrl-j ----------------------- If none of the above described targets is left Ctrl-j can be used to jump behind closing brackets, parenthesis, braces, or string terminators ('"`). This feature is limited to the current line. Ctrl-j does not jump behind the last character in a line. How to switch the mapping for Ctrl-j off ---------------------------------------- The original meaning of Ctrl-j is 'move [n] lines downward' (see |CTRL-j|). If you are accustomed to use the deafult and don't like these jump targets you can switch them off. Put the following line in the file .vimrc : let g:C_Ctrl_j = 'off' The default value of g:C_Ctrl_j is 'on'. You do not have to change the template files. All jump targets will be removed before a template will be inserted. ============================================================================== 5.4 SWITCHING BETWEEN TEMPLATE SETS *csupport-templates-sets* ============================================================================== This plugin comes with two sets of templates. These are suggestions. You may want to have additional sets for different projects or occasionally want to use doxygen style comments. To facilitate switching use the macro*|STYLE|* (|csupport-templates-files|) to define a unique name and the IF-ENDIF-construct to choose a particular set of files for example: ... *|STYLE|* = C $ $ ============================================================= $ ========== FILE INCLUDES ==================================== $ ============================================================= $ == IF *|STYLE|* IS C == $ |includefile| = c.comments.template |includefile| = c.cpp.template |includefile| = c.idioms.template |includefile| = c.preprocessor.template |includefile| = c.statements.template $ == ENDIF == ... The syntax is as follows: == IF macro_name IS macro_value == == ENDIF == Includes outside an IF-ENDIF construct are associated with the default style 'default'. A style set does not have to a complete set of templates. For an incomplete set the other templates are taken from the default style. IF, IS, and ENDIF are keywords. HINT. Use these constructs to avoid overwriting your templates when updating csupport. Copy and rename the set of files you want to change and surround the includes with an appropriate IF-construct: *|STYLE|* = MY_C $ ... $ == IF *|STYLE|* IS MY_C == |includefile| = my_c.comments.template |includefile| = my_c.cpp.template |includefile| = my_c.idioms.template |includefile| = my_c.preprocessor.template |includefile| = my_c.statements.template == ENDIF == Keep a copy of the main template file 'Templates' because this file will be overwritten if you do not update manually. ============================================================================== 5.5 BINDING A STYLE TO A FILE EXTENSION *csupport-templates-bind* ============================================================================== You can bind the existing styles to one or more filename extensions. To do so assign a Dictionary to the global variable g:C_Styles in '~/.vimrc' : let g:C_Styles = { '*.c,*.h' : 'default', '*.cc,*.cpp,*.hh' : 'CPP' } A Dictionary is created with a comma separated list of entries in curly braces. Each entry has a key and a value, separated by a colon. Each key can only appear once. The keys are themselves a comma separated list of filename pattern. The values are existing styles defined in the template files. The given style will be set automatically when switching to a buffer or opening a new buffer with the associated filename pattern and supersedes the macro *|STYLE|* . ============================================================================== 6. C/C++ DICTIONARY *csupport-dictionary* ============================================================================== The files c-c++-keywords.list k+r.list stl_index.list are a part of this plugin and can be used (together with your own lists) as dictionaries for automatic word completion. This feature is enabled by default. The default word lists are plugin_dir/c-support/wordlists/c-c++-keywords.list plugin_dir/c-support/wordlists/k+r.list plugin_dir/c-support/wordlists/stl_index.list The variable plugin_dir will automatically be set by the plugin to one of the following values: $HOME.'/.vim/' for Linux/Unix $VIM.'/vimfiles/' for Windows If you want to use an additional list MyC.list put the following lines into ~/.vimrc : let g:C_Dictionary_File = PLUGIN_DIR.'/c-support/wordlists/c-c++-keywords.list,'. \ PLUGIN_DIR.'/c-support/wordlists/k+r.list,'. \ PLUGIN_DIR.'/c-support/wordlists/stl_index.list,'. \ PLUGIN_DIR.'/c-support/wordlists/MyC.list' When in file ~/.vimrc the name PLUGIN_DIR has to be replaced by $HOME or $VIM (see above). Whitespaces in the pathnames have to be escaped with a backslash. The right side is a comma separated list of files. Note the point at the end of the first line (string concatenation) and the backslash in front of the second line (continuation line). You can use Vim's dictionary feature CTRL-X, CTRL-K (and CTRL-P, CTRL-N). ============================================================================== 7. EXTENDING ctags *csupport-ctags* ============================================================================== ------------------------------------------------------------------------------ 7.1 make AND qmake *csupport-ctags-make* ------------------------------------------------------------------------------ The use of the Vim plugin taglist.vim (Author: Yegappan Lakshmanan) is highly recommended. It uses the program ctags which generates tag files for 3 dozen languages (Exuberant Ctags, Darren Hiebert, http://ctags.sourceforge.net). With the following extensions the list of targets in a makefile can be shown in the taglist window. 1) Append the file customization.ctags to the file $HOME/.ctags . 2) Add the following lines (from customization.vimrc) to $HOME/.vimrc : " "------------------------------------------------------------------- " taglist.vim : toggle the taglist window " taglist.vim : define the title texts for make " taglist.vim : define the title texts for qmake "------------------------------------------------------------------- noremap :Tlist inoremap :Tlist let tlist_make_settings = 'make;m:makros;t:targets;i:includes' let tlist_qmake_settings = 'qmake;t:SystemVariables' if has("autocmd") " ---------- qmake : set file type for *.pro ---------- autocmd BufNewFile,BufRead *.pro set filetype=qmake endif " has("autocmd") 3) restart vim/gvim The two maps will toggle the taglist window (hotkey F11) in all editing modes. The two assignments define the headings for the (q)make sections in the taglist window. The autocmd set the file type 'qmake' for the filename extension 'pro' (ctags needs this). ------------------------------------------------------------------------------ 7.2 TEMPLATES *csupport-ctags-templates* ------------------------------------------------------------------------------ If you frequently change the plugin templates and you are using the taglist plugin (section above) you may want to use this plugin for navigation. This is achieved in two steps. First add a new language definition to the file $HOME/.ctags : --langdef=template --langmap=template:.template,TEMPLATE --regex-template=/^==\s+([^=]+)\s+==\s*(\s+==\s+([^=]+)\s+==)?/\1/t,template/ Now add the following lines to the file $HOME/.vimrc : let tlist_template_settings = 'template;t:template' "--------------------------------------------------------------- " plugin templates : set filetype for *.template "--------------------------------------------------------------- if has("autocmd") autocmd BufNewFile,BufRead Templates set filetype=template autocmd BufNewFile,BufRead *.template set filetype=template endif " has("autocmd") The assignment defines the heading for the template section in the taglist window. The autocmds set the file type 'template' for the main template file 'Templates' and the includefiles '*.template' (if any). ============================================================================== 8. FOLDING *csupport-folding* ============================================================================== This plugin can be used together with folding. There are a few peculiarities when the cursor is on a closed fold before inserting a template: Normal mode ----------- Inserting blocks of complete lines below and above a fold (e.g. frame comments) and inserting at the top of a buffer (e.g. file description) works as usual. Insertions which go to the end of a line (e.g. end-of-line comments) and insertions which go to the cursor position (e.g. 'sizeof()') will be suppressed and a warning will be shown. Visual mode ----------- A range of lines containing closed folds can be surrounded by constructs which have a visual mode, e.g. a for-loop: for ( ; ; ) { +--- 4 lines: {------------------------------------------------------------ } See |folding| for more information on folding. ============================================================================== 9. Additional Mappings *csupport-ad-mappings* ============================================================================== There are a few additional filetype specific key mappings defined in '~/.vim/ftplugin/c.vim'. Complete a classical C comment: '/*' => '/* | */' (modes: i,v). Complete a classical C multi-line comment (mode: i): '/*' => /* * | */ Open a block (modes: i,v): '{' => { | } In visual mode the content of the new block will be indented. ============================================================================== 10. WINDOWS PARTICULARITIES *csupport-windows* ============================================================================== For a user installation the plugin should go into the directory structure below $HOME/vimfiles/ for a system installation below $VIM/vimfiles/ The values of the two variables can be found from inside Vim: :echo $VIM or :echo $HOME The configuration files for a user are $HOME/_vimrc and $HOME/_gvimrc for the system $VIM/_vimrc and $VIM/_gvimrc Compiler settings: It could be necessary to add further settings for your compiler. To compile C++-programs using a Dev-C++ installation (http://www.bloodshed.net) the following item in $VIM/_vimrc is needed (depends on the Dev-C++ install directory): let g:C_CFlags = '-Wall -g -o0 -c -I c:\programs\dev-c++\include\g++' ============================================================================== 11. ADDITIONAL TIPS *csupport-tips* ============================================================================== (1) gVim. Toggle 'insert mode' <--> 'normal mode' with the right mouse button (see mapping in file costumization.gvimrc). (2) gVim. Use tear off menus. (3) Try 'Focus under mouse' as window behavior (No mouse click when the mouse pointer is back from the menu item). (4) Use Emulate3Buttons "on" (X11) even for a 3-button mouse. Pressing left and right button at the same time without moving your fingers is faster then moving a finger to the middle button (often a wheel). ============================================================================== 12. TROUBLESHOOTING *csupport-troubleshooting* ============================================================================== * I do not see any new main menu item. - Was the archive extracted into the right directory? * How can I see what was loaded? - Use ':scriptnames' from the Vim command line. * No main menu item. - Loading of plugin files must be enabled. If not use :filetype plugin on This is the minimal content of the file '$HOME/.vimrc'. Create one if there is none, or better use customization.vimrc. * Most key mappings do not work. - They are defined in a filetype plugin in '$HOME/.vim/ftplugin/'. Use ':filetype' to check if filetype plugins are enabled. If not, add the line filetype plugin on to the file '~/.vimrc'. * Some hotkeys do not work. - The hotkeys might be in use by your graphical desktop environment. Under KDE Ctrl-F9 is the hotkey which let you switch to the 9. desktop. The key settings can usually be redefined. * Splint and/or CodeCheck menu item not visible. - The program is not installed or not found (path not set) or not executable. ============================================================================== 13.
