1. Intro *syntastic-intro*
|
|
|
|
Syntastic is a syntax checking plugin that runs files through external syntax
|
|
checkers. This can be done on demand, or automatically as files are saved and
|
|
opened. If syntax errors are detected, the user is notified and is happy
|
|
because they didn't have to compile their code or execute their script to find
|
|
them.
|
|
|
|
Syntastic comes in two parts: the syntax checker plugins, and the core. The
|
|
syntax checker plugins are defined on a per-filetype basis where each one wraps
|
|
up an external syntax checking program. The core script delegates off to these
|
|
plugins and uses their output to provide the syntastic functionality.
|
|
|
|
Take a look at the wiki for a list of supported filetypes and checkers:
|
|
|
|
https://github.com/scrooloose/syntastic/wiki/Syntax-Checkers
|
|
|
|
Note: This doc only deals with using syntastic. To learn how to write syntax
|
|
checker integrations, see the guide on the GitHub wiki:
|
|
|
|
https://github.com/scrooloose/syntastic/wiki/Syntax-Checker-Guide
|
|
|
|
------------------------------------------------------------------------------
|
|
1.1. Quick start *syntastic-quickstart*
|
|
|
|
Syntastic comes preconfigured with a default list of enabled checkers per
|
|
filetype. This list is kept reasonably short to prevent slowing down Vim or
|
|
trying to use conflicting checkers.
|
|
|
|
You can see the list of checkers available for the current filetype with the
|
|
|:SyntasticInfo| command.
|
|
|
|
You probably want to override the configured list of checkers for the
|
|
filetypes you use, and also change the arguments passed to specific checkers
|
|
to suit your needs. See |syntastic-checker-options| below for details.
|
|
|
|
Use |:SyntasticCheck| to manually check right now. Use |:Errors| to open the
|
|
|location-list| window, and |:lclose| to close it. You can clear the error
|
|
list with |:SyntasticReset|, and you can use |:SyntasticToggleMode| to switch
|
|
between active (checking on writing the buffer) and passive (manual) checking.
|
|
|
|
You don't have to switch focus to the |location-list| window to jump to the
|
|
different errors. Vim provides several built-in commands for this, for
|
|
example |:lnext| and |:lprevious|. You may want to add shortcut mappings for
|
|
these commands, or perhaps install a plugin such as Tim Pope's 'unimpaired'
|
|
(see https://github.com/tpope/vim-unimpaired) that provides such mappings.
|
|
|
|
------------------------------------------------------------------------------
|
|
1.2. Recommended settings *syntastic-recommended*
|
|
|
|
Syntastic has a large number of options that can be configured, and the
|
|
defaults are not particularly well suitable for new users. It is recommended
|
|
that you start by adding the following lines to your vimrc, and return to them
|
|
later as needed: >
|
|
set statusline+=%#warningmsg#
|
|
set statusline+=%{SyntasticStatuslineFlag()}
|
|
set statusline+=%*
|
|
|
|
let g:syntastic_always_populate_loc_list = 1
|
|
let g:syntastic_auto_loc_list = 1
|
|
let g:syntastic_check_on_open = 1
|
|
let g:syntastic_check_on_wq = 0
|
|
<
|
|
==============================================================================
|
|
2. Functionality provided *syntastic-functionality*
|
|
|
|
Syntax checking can be done automatically or on demand (see
|
|
|'syntastic_mode_map'| and |:SyntasticToggleMode| for configuring this).
|
|
|
|
When syntax checking is done, the features below can be used to notify the
|
|
user of errors. See |syntastic-global-options| for how to configure and
|
|
activate/deactivate these features.
|
|
|
|
* A statusline flag
|
|
* Signs beside lines with errors
|
|
* The |location-list| can be populated with the errors for the associated
|
|
buffer
|
|
* Erroneous parts of lines can be highlighted (this functionality is only
|
|
provided by some syntax checkers)
|
|
* Balloons (if the |+balloon_eval| feature is compiled in) can be used to
|
|
display error messages for erroneous lines when hovering the mouse over
|
|
them
|
|
* Error messages from multiple checkers can be aggregated in a single list
|
|
|
|
------------------------------------------------------------------------------
|
|
2.1. The statusline flag *syntastic-statusline-flag*
|
|
|
|
To use the statusline flag, this must appear in your |'statusline'| setting >
|
|
%{SyntasticStatuslineFlag()}
|
|
<
|
|
Something like this could be more useful: >
|
|
set statusline+=%#warningmsg#
|
|
set statusline+=%{SyntasticStatuslineFlag()}
|
|
set statusline+=%*
|
|
<
|
|
When syntax errors are detected a flag will be shown. The content of the flag
|
|
is derived from the |syntastic_stl_format| option.
|
|
|
|
------------------------------------------------------------------------------
|
|
2.2. Error signs *syntastic-error-signs*
|
|
|
|
Syntastic uses the |:sign| commands to mark lines with errors and warnings in
|
|
the sign column. To enable this feature, use the |'syntastic_enable_signs'|
|
|
option.
|
|
|
|
Signs are colored using the Error and Todo syntax highlight groups by default.
|
|
If you wish to customize the colors for the signs, you can use the following
|
|
groups:
|
|
SyntasticErrorSign - For syntax errors, links to 'error' by default
|
|
SyntasticWarningSign - For syntax warnings, links to 'todo' by default
|
|
SyntasticStyleErrorSign - For style errors, links to 'SyntasticErrorSign'
|
|
by default
|
|
SyntasticStyleWarningSign - For style warnings, links to
|
|
'SyntasticWarningSign' by default
|
|
|
|
Example: >
|
|
highlight SyntasticErrorSign guifg=white guibg=red
|
|
<
|
|
To set up highlighting for the line where a sign resides, you can use the
|
|
following highlight groups:
|
|
SyntasticErrorLine
|
|
SyntasticWarningLine
|
|
SyntasticStyleErrorLine - Links to 'SyntasticErrorLine' by default
|
|
SyntasticStyleWarningLine - Links to 'SyntasticWarningLine' by default
|
|
|
|
Example: >
|
|
highlight SyntasticErrorLine guibg=#2f0000
|
|
<
|
|
------------------------------------------------------------------------------
|
|
2.3. The error window *syntastic-error-window*
|
|
|
|
You can use the |:Errors| command to display the errors for the current buffer
|
|
in the |location-list|.
|
|
|
|
Note that when you use |:Errors| the current location list is overwritten with
|
|
Syntastic's own location list. The location list is also overwritten when
|
|
|syntastic_auto_jump| is non-zero and the cursor has to jump to an issue.
|
|
|
|
By default syntastic doesn't fill the |location-list| with the errors found by
|
|
the checkers, in order to reduce clashes with other plugins. Consequently, if
|
|
you run |:lopen| or |:lwindow| rather than |:Errors| to open the error window you
|
|
wouldn't see syntastic's list of errors. If you insist on using |:lopen| or
|
|
|:lwindow| you should either run |:SyntasticSetLoclist| after running the checks,
|
|
or set |syntastic_always_populate_loc_list| which tells syntastic to update the
|
|
|location-list| automatically.
|
|
|
|
------------------------------------------------------------------------------
|
|
2.4. Error highlighting *syntastic-highlighting*
|
|
|
|
Some checkers provide enough information for syntastic to be able to highlight
|
|
errors. By default the SpellBad syntax highlight group is used to color errors,
|
|
and the SpellCap group is used for warnings. If you wish to customize the
|
|
colors for highlighting you can use the following groups:
|
|
SyntasticError - Links to 'SpellBad' by default
|
|
SyntasticWarning - Links to 'SpellCap' by default
|
|
SyntasticStyleError - Links to SyntasticError by default
|
|
SyntasticStyleWarning - Links to SyntasticWarning by default
|
|
|
|
Example: >
|
|
highlight SyntasticError guibg=#2f0000
|
|
<
|
|
------------------------------------------------------------------------------
|
|
2.5. Aggregating errors *syntastic-aggregating-errors*
|
|
|
|
By default, namely if |'syntastic_aggregate_errors'| is unset, syntastic runs
|
|
in turn the checkers corresponding to the filetype of the current file (see
|
|
|syntastic-filetype-checkers|), and stops as soon as a checker reports any
|
|
errors. It then notifies you of the errors using the notification mechanisms
|
|
above. In this mode error lists are always produced by a single checker, and,
|
|
if you open the error window, the name of the checker that generated the errors
|
|
is shown on the statusline of the error window.
|
|
|
|
If |'syntastic_aggregate_errors'| is set, syntastic runs all checkers that
|
|
apply (still cf. |syntastic-filetype-checkers|), then aggregates errors found
|
|
by all checkers in a single list, and notifies you. In this mode each error
|
|
message is labeled with the name of the checker that generated it, but you can
|
|
disable generation of these labels by turning off '|syntastic_id_checkers|'.
|
|
|
|
If |'syntastic_sort_aggregated_errors'| is set (which is the default), messages
|
|
in the aggregated list are grouped by file, then sorted by line number, then
|
|
type, then column number. Otherwise messages produced by the same checker are
|
|
grouped together, and sorting within each group is decided by the variables
|
|
|'syntastic_<filetype>_<checker>_sort'|.
|
|
|
|
------------------------------------------------------------------------------
|
|
2.6 Filtering errors *syntastic-filtering-errors*
|
|
|
|
You can selectively disable some of the errors found by checkers either
|
|
using |'syntastic_quiet_messages'|, or by specifying a list of patterns in
|
|
|'syntastic_ignore_files'|.
|
|
|
|
See also: |'syntastic_<filetype>_<checker>_quiet_messages'|.
|
|
|
|
==============================================================================
|
|
3. Commands *syntastic-commands*
|
|
|
|
:Errors *:Errors*
|
|
|
|
When errors have been detected, use this command to pop up the |location-list|
|
|
and display the error messages.
|
|
|
|
Please note that the |:Errors| command overwrites the current location list with
|
|
syntastic's own location list.
|
|
|
|
:SyntasticToggleMode *:SyntasticToggleMode*
|
|
|
|
Toggles syntastic between active and passive mode. See |'syntastic_mode_map'|
|
|
for more info.
|
|
|
|
:SyntasticCheck *:SyntasticCheck*
|
|
|
|
Manually cause a syntax check to be done. By default the checkers in the
|
|
|'g:syntastic_<filetype>_checkers'| or |'b:syntastic_checkers'| lists are run,
|
|
cf. |syntastic-filetype-checkers|. If |syntastic_aggregate_errors| is unset
|
|
(which is the default), checking stops the first time a checker reports any
|
|
errors; if |syntastic_aggregate_errors| is set, all checkers that apply are run
|
|
in turn, and all errors found are aggregated in a single list.
|
|
|
|
The command may be followed by a (space separated) list of checkers. In this
|
|
case |'g:syntastic_<filetype>_checkers'| and |'b:syntastic_checkers'| are
|
|
ignored, and the checkers named by the command's arguments are run instead, in
|
|
the order specified. The rules of |syntastic_aggregate_errors| still apply.
|
|
|
|
Example: >
|
|
:SyntasticCheck flake8 pylint
|
|
<
|
|
:SyntasticInfo *:SyntasticInfo*
|
|
|
|
The command takes an optional argument, and outputs information about the
|
|
checkers available for the filetype named by said argument, or for the current
|
|
filetype if no argument was provided.
|
|
|
|
:SyntasticReset *:SyntasticReset*
|
|
|
|
Resets the list of errors and turns off all error notifiers.
|
|
|
|
:SyntasticSetLoclist *:SyntasticSetLoclist*
|
|
|
|
If |'syntastic_always_populate_loc_list'| is not set, the |location-list| is
|
|
not filled in automatically with the list of errors detected by the checkers.
|
|
This is useful if you run syntastic along with other plugins that use location
|
|
lists. The |:SyntasticSetLoclist| command allows you to stick the errors into
|
|
the location list explicitly.
|
|
|
|
==============================================================================
|
|
4. Global Options *syntastic-global-options*
|
|
|
|
|
|
*'syntastic_check_on_open'*
|
|
Default: 0
|
|
If enabled, syntastic will do syntax checks when buffers are first loaded as
|
|
well as on saving >
|
|
let g:syntastic_check_on_open = 1
|
|
<
|
|
*'syntastic_check_on_wq'*
|
|
Default: 1
|
|
Normally syntastic runs syntax checks whenever buffers are written to disk.
|
|
If you want to skip these checks when you issue |:wq|, |:x|, and |:ZZ|, set this
|
|
variable to 0. >
|
|
let g:syntastic_check_on_wq = 0
|
|
<
|
|
*'syntastic_aggregate_errors'*
|
|
Default: 0
|
|
When enabled, syntastic runs all checkers that apply to the current filetype,
|
|
then aggregates errors found by all checkers and displays them. When disabled,
|
|
syntastic runs each checker in turn, and stops to display the results the first
|
|
time a checker finds any errors. >
|
|
let g:syntastic_aggregate_errors = 1
|
|
<
|
|
*'syntastic_id_checkers'*
|
|
Default: 1
|
|
When results from multiple checkers are aggregated in a single error list
|
|
(that is either when |syntastic_aggregate_errors| is enabled, or when checking
|
|
a file with a composite filetype), it might not be immediately obvious which
|
|
checker has produced a given error message. This variable instructs syntastic
|
|
to label error messages with the names of the checkers that created them. >
|
|
let g:syntastic_id_checkers = 0
|
|
<
|
|
*'syntastic_sort_aggregated_errors'*
|
|
Default: 1
|
|
By default, when results from multiple checkers are aggregated in a single
|
|
error list (that is either when |syntastic_aggregate_errors| is enabled, or
|
|
when checking a file with a composite filetype), errors are grouped by file,
|
|
then sorted by line number, then grouped by type (namely errors take precedence
|
|
over warnings), then they are sorted by column number. If you want to leave
|
|
messages grouped by checker output, set this variable to 0. >
|
|
let g:syntastic_sort_aggregated_errors = 0
|
|
<
|
|
*'syntastic_echo_current_error'*
|
|
Default: 1
|
|
If enabled, syntastic will echo current error to the command window. If
|
|
multiple errors are found on the same line, |syntastic_cursor_columns| is used
|
|
to decide which one is shown. >
|
|
let g:syntastic_echo_current_error = 1
|
|
<
|
|
*'syntastic_cursor_columns'*
|
|
Default: 1
|
|
This option controls which errors are echoed to the command window if
|
|
|syntastic_echo_current_error| is set and multiple errors are found on the same
|
|
line. When the option is enabled, the first error corresponding to the current
|
|
column is show. Otherwise, the first error on the current line is echoed,
|
|
regardless of the cursor position on the current line.
|
|
|
|
When dealing with very large lists of errors, disabling this option can speed
|
|
up navigation significantly: >
|
|
let g:syntastic_cursor_column = 0
|
|
<
|
|
*'syntastic_enable_signs'*
|
|
Default: 1
|
|
Use this option to tell syntastic whether to use the |:sign| interface to mark
|
|
syntax errors: >
|
|
let g:syntastic_enable_signs = 1
|
|
<
|
|
*'syntastic_error_symbol'* *'syntastic_style_error_symbol'*
|
|
*'syntastic_warning_symbol'* *'syntastic_style_warning_symbol'*
|
|
Use this option to control what the syntastic |:sign| text contains. Several
|
|
error symbols can be customized:
|
|
syntastic_error_symbol - For syntax errors, defaults to '>>'
|
|
syntastic_style_error_symbol - For style errors, defaults to 'S>'
|
|
syntastic_warning_symbol - For syntax warnings, defaults to '>>'
|
|
syntastic_style_warning_symbol - For style warnings, defaults to 'S>'
|
|
|
|
Example: >
|
|
let g:syntastic_error_symbol = "✗"
|
|
let g:syntastic_warning_symbol = "⚠"
|
|
<
|
|
*'syntastic_enable_balloons'*
|
|
Default: 1
|
|
Use this option to tell syntastic whether to display error messages in balloons
|
|
when the mouse is hovered over erroneous lines: >
|
|
let g:syntastic_enable_balloons = 1
|
|
<
|
|
Note that Vim must be compiled with |+balloon_eval|.
|
|
|
|
*'syntastic_enable_highlighting'*
|
|
Default: 1
|
|
Use this option to tell syntastic whether to use syntax highlighting to mark
|
|
errors (where possible). Highlighting can be turned off with the following >
|
|
let g:syntastic_enable_highlighting = 0
|
|
<
|
|
*'syntastic_always_populate_loc_list'*
|
|
Default: 0
|
|
Enable this option to tell syntastic to always stick any detected errors into
|
|
the |location-list|: >
|
|
let g:syntastic_always_populate_loc_list = 1
|
|
<
|
|
*'syntastic_auto_jump'*
|
|
Default: 0
|
|
Enable this option if you want the cursor to jump to the first detected issue
|
|
when saving or opening a file.
|
|
|
|
When set to 0 the cursor won't jump automatically. >
|
|
let g:syntastic_auto_jump = 0
|
|
<
|
|
When set to 1 the cursor will always jump to the first issue detected,
|
|
regardless of type. >
|
|
let g:syntastic_auto_jump = 1
|
|
<
|
|
When set to 2 the cursor will jump to the first issue detected, but only if
|
|
this issue is an error. >
|
|
let g:syntastic_auto_jump = 2
|
|
<
|
|
When set to 3 the cursor will jump to the first error detected, if any. If
|
|
all issues detected are warnings, the cursor won't jump. >
|
|
let g:syntastic_auto_jump = 3
|
|
<
|
|
*'syntastic_auto_loc_list'*
|
|
Default: 2
|
|
Use this option to tell syntastic to automatically open and/or close the
|
|
|location-list| (see |syntastic-error-window|).
|
|
|
|
When set to 0 the error window will not be opened or closed automatically. >
|
|
let g:syntastic_auto_loc_list = 0
|
|
<
|
|
When set to 1 the error window will be automatically opened when errors are
|
|
detected, and closed when none are detected. >
|
|
let g:syntastic_auto_loc_list = 1
|
|
<
|
|
When set to 2 the error window will be automatically closed when no errors are
|
|
detected, but not opened automatically. >
|
|
let g:syntastic_auto_loc_list = 2
|
|
<
|
|
*'syntastic_loc_list_height'*
|
|
Default: 10
|
|
Use this option to specify the height of the location lists that syntastic
|
|
opens. >
|
|
let g:syntastic_loc_list_height = 5
|
|
<
|
|
*'syntastic_ignore_files'*
|
|
Default: []
|
|
Use this option to specify files that syntastic should never check. It's a
|
|
list of |regular-expression| patterns. The full paths of files (see |::p|) are
|
|
matched against these patterns, and the matches are case sensitive. Use |\c|
|
|
to specify case insensitive patterns. Example: >
|
|
let g:syntastic_ignore_files = ['\m^/usr/include/', '\m\c\.h$']
|
|
<
|
|
*'syntastic_filetype_map'*
|
|
Default: {}
|
|
Use this option to map non-standard filetypes to standard ones. Corresponding
|
|
checkers are mapped accordingly, which allows syntastic to check files with
|
|
non-standard filetypes: >
|
|
let g:syntastic_filetype_map = {
|
|
\ "plaintex": "tex",
|
|
\ "gentoo-metadata": "xml" }
|
|
<
|
|
Composite filetypes can also be mapped to simple types, which disables the
|
|
default behaviour of running both checkers against the input file: >
|
|
let g:syntastic_filetype_map = { "handlebars.html": "handlebars" }
|
|
<
|
|
*'syntastic_mode_map'*
|
|
Default: { "mode": "active",
|
|
"active_filetypes": [],
|
|
"passive_filetypes": [] }
|
|
Use this option to fine tune when automatic syntax checking is done (or not
|
|
done).
|
|
|
|
The option should be set to something like: >
|
|
|
|
let g:syntastic_mode_map = {
|
|
\ "mode": "active",
|
|
\ "active_filetypes": ["ruby", "php"],
|
|
\ "passive_filetypes": ["puppet"] }
|
|
<
|
|
"mode" can be mapped to one of two values - "active" or "passive". When set
|
|
to "active", syntastic does automatic checking whenever a buffer is saved or
|
|
initially opened. When set to "passive" syntastic only checks when the user
|
|
calls |:SyntasticCheck|.
|
|
|
|
The exceptions to these rules are defined with "active_filetypes" and
|
|
"passive_filetypes". In passive mode, automatic checks are still done for
|
|
filetypes in the "active_filetypes" array (and "passive_filetypes" is
|
|
ignored). In active mode, automatic checks are not done for any filetypes in
|
|
the "passive_filetypes" array ("active_filetypes" is ignored).
|
|
|
|
If any of "mode", "active_filetypes", or "passive_filetypes" are left
|
|
unspecified, they default to values above.
|
|
|
|
If local variable |'b:syntastic_mode'| is defined its value takes precedence
|
|
over all calculations involving |'syntastic_mode_map'| for the corresponding
|
|
buffer.
|
|
|
|
At runtime, the |:SyntasticToggleMode| command can be used to switch between
|
|
active and passive modes.
|
|
|
|
*'b:syntastic_mode'*
|
|
Default: unset
|
|
Only the local form |'b:syntastic_mode'| is used. When set to either "active"
|
|
or "passive", it takes precedence over |'syntastic_mode_map'| when deciding
|
|
whether the corresponding buffer should be checked automatically.
|
|
|
|
*'syntastic_quiet_messages'*
|
|
Default: {}
|
|
Use this option to filter out some of the messages produced by checkers. The
|
|
option should be set to something like: >
|
|
let g:syntastic_quiet_messages = {
|
|
\ "!level": "errors",
|
|
\ "type": "style",
|
|
\ "regex": '\m\[C03\d\d\]',
|
|
\ "file:p": ['\m^/usr/include/', '\m\c\.h$'] }
|
|
<
|
|
Each element turns off messages matching the patterns specified by the
|
|
corresponding value. Values are lists, but if a list consist of a single
|
|
element you may omit the brackets (e.g. you may write "style" instead of
|
|
["style"]). Elements with values [] or '' are ignored (this is useful for
|
|
overriding filters, cf. |filter-overrides|).
|
|
|
|
"level" - takes one of two values, "warnings" or "errors"
|
|
"type" - can be either "syntax" or "style"
|
|
"regex" - is matched against the messages' text as a case insensitive
|
|
|regular-expression|
|
|
"file" - is matched against the filenames the messages refer to, as a
|
|
case sensitive |regular-expression|.
|
|
|
|
If a key is prefixed by an exclamation mark "!", the corresponding filter is
|
|
negated (i.e. the above example silences all messages that are NOT errors).
|
|
|
|
The "file" key may be followed by one or more filename modifiers (see
|
|
|filename-modifiers|). The modifiers are applied to the filenames the messages
|
|
refer to before matching against the value (i.e. in the above example the full
|
|
path of the issues are matched against '\m^/usr/include/' and '\m\c\.h$').
|
|
|
|
If |'syntastic_id_checkers'| is set, filters are applied before error messages
|
|
are labeled with the names of the checkers that created them.
|
|
|
|
There are also checker-specific variants of this option, providing finer
|
|
control. They are named |'syntastic_<filetype>_<checker>_quiet_messages'|.
|
|
|
|
For a particular checker, if both a |'syntastic_quiet_messages'| filter and
|
|
a checker-specific filter are present, they are both applied (to the list of
|
|
errors produced by the said checker). In case of conflicting values for the
|
|
same keys, the values of the checker-specific filters take precedence.
|
|
|
|
*filter-overrides*
|
|
Since filter elements with values [] or '' are ignored, you can disable global
|
|
filters for particular checkers, by setting the values of the corresponding
|
|
elements in |'syntastic_<filetype>_<checker>_quiet_messages'| to [] or ''. For
|
|
example, the following setting will silence all warnings, except for the
|
|
ones produced by "pylint": >
|
|
let g:syntastic_quiet_messages = { "level": "warnings" }
|
|
let g:syntastic_python_pylint_quiet_messages = { "level" : [] }
|
|
<
|
|
*'syntastic_stl_format'*
|
|
Default: [Syntax: line:%F (%t)]
|
|
Use this option to control what the syntastic statusline text contains. Several
|
|
magic flags are available to insert information:
|
|
%e - number of errors
|
|
%w - number of warnings
|
|
%t - total number of warnings and errors
|
|
%fe - line number of first error
|
|
%fw - line number of first warning
|
|
%F - line number of first warning or error
|
|
|
|
Several additional flags are available to hide text under certain conditions:
|
|
%E{...} - hide the text in the brackets unless there are errors
|
|
%W{...} - hide the text in the brackets unless there are warnings
|
|
%B{...} - hide the text in the brackets unless there are both warnings AND
|
|
errors
|
|
These flags can't be nested.
|
|
|
|
Example: >
|
|
let g:syntastic_stl_format = '[%E{Err: %fe #%e}%B{, }%W{Warn: %fw #%w}]'
|
|
<
|
|
If this format is used and the current buffer has 5 errors and 1 warning
|
|
starting on lines 20 and 10 respectively then this would appear on the
|
|
statusline: >
|
|
[Err: 20 #5, Warn: 10 #1]
|
|
<
|
|
If the buffer had 2 warnings, starting on line 5 then this would appear: >
|
|
[Warn: 5 #2]
|
|
<
|
|
*'b:syntastic_skip_checks'*
|
|
Default: unset
|
|
Only the local form |'b:syntastic_skip_checks'| is used. When set to a true
|
|
value, no checks are run against the corresponding buffer. Example: >
|
|
let b:syntastic_skip_checks = 1
|
|
<
|
|
*'syntastic_full_redraws'*
|
|
Default: 0 in GUI Vim and MacVim, 1 otherwise
|
|
Controls whether syntastic calls |:redraw| or |:redraw!| for screen redraws.
|
|
Changing it can in principle make screen redraws smoother, but it can also
|
|
cause screen to flicker, or cause ghost characters. Leaving it to the default
|
|
should be safe.
|
|
|
|
*'syntastic_exit_checks'*
|
|
Default: 0 when running under "cmd.exe" on Windows, 1 otherwise
|
|
Syntastic attempts to catch abnormal termination conditions from checkers by
|
|
looking at their exit codes. The "cmd.exe" shell on Windows make these checks
|
|
meaningless, by returning 1 to Vim when the checkers exit with non-zero codes.
|
|
The above variable can be used to disable exit code checks in syntastic.
|
|
|
|
*'syntastic_shell'*
|
|
Default: Vim's 'shell'
|
|
|
|
This is the (full path to) the shell syntastic will use to run the checkers.
|
|
On UNIX and Mac OS-X this shell must accept Bourne-compatible syntax for
|
|
file "stdout" and "stderr" redirections ">file" and "2>file". Examples of
|
|
compatible shells are "zsh", "bash", "ksh", and of course the original Bourne
|
|
"sh".
|
|
|
|
This shell is independent of Vim's 'shell', and it isn't used for interactive
|
|
operations. It must take care to initialize all environment variables needed
|
|
by the checkers you're using. Example: >
|
|
let g:syntastic_shell = "/bin/sh"
|
|
<
|
|
*'syntastic_debug'*
|
|
Default: 0
|
|
Set this to the sum of one or more of the following flags to enable
|
|
debugging:
|
|
|
|
1 - trace general workflow
|
|
2 - dump location lists
|
|
4 - trace notifiers
|
|
8 - trace autocommands
|
|
16 - dump options
|
|
32 - trace running of specific checkers
|
|
|
|
Example: >
|
|
let g:syntastic_debug = 1
|
|
<
|
|
Syntastic will then add debugging messages to Vim's |message-history|. You can
|
|
examine these messages with |:mes|.
|
|
|
|
*'syntastic_debug_file'*
|
|
Default: unset
|
|
When set, debugging messages are written to the file named by its value, in
|
|
addition to being added to Vim's |message-history|: >
|
|
let g:syntastic_debug_file = '~/syntastic.log'
|
|
<
|
|
*'syntastic_extra_filetypes'*
|
|
Default: []
|
|
List of filetypes handled by checkers external to syntastic. If you have a Vim
|
|
plugin that adds a checker for syntastic, and if the said checker deals with a
|
|
filetype that is unknown to syntastic, you might consider adding that filetype
|
|
to this list: >
|
|
let g:syntastic_extra_filetypes = [ "make", "gitcommit" ]
|
|
<
|
|
This will allow |:SyntasticInfo| to do proper tab completion for the new
|
|
filetypes.
|
|
|

==============================================================================
|
|
5. Checker Options *syntastic-checker-options*
|
|
|
|
------------------------------------------------------------------------------
|
|
5.1 Choosing which checkers to use *syntastic-filetype-checkers*
|
|
|
|
*'g:syntastic_<filetype>_checkers'*
|
|
You can tell syntastic which checkers to run for a given filetype by setting a
|
|
variable 'g:syntastic_<filetype>_checkers' to a list of checkers, e.g. >
|
|
let g:syntastic_php_checkers = ["php", "phpcs", "phpmd"]
|
|
<
|
|
*'b:syntastic_checkers'*
|
|
There is also a per-buffer version of this setting, 'b:syntastic_checkers'.
|
|
When set, it takes precedence over |'g:syntastic_<filetype>_checkers'|. You can
|
|
use this in an autocmd to configure specific checkers for particular paths: >
|
|
autocmd FileType python if stridx(expand("%:p"), "/some/path/") == 0 |
|
|
\ let b:syntastic_checkers = ["pylint"] | endif
|
|
<
|
|
If neither |'g:syntastic_<filetype>_checkers'| nor |'b:syntastic_checkers'|
|
|
is set, a default list of checker is used. Beware however that this list
|
|
deliberately kept minimal, for performance reasons.
|
|
|
|
Take a look at the wiki to find out what checkers and filetypes are supported
|
|
by syntastic:
|
|
|
|
https://github.com/scrooloose/syntastic/wiki/Syntax-Checkers
|
|
|
|
Use |:SyntasticInfo| to see which checkers are available for a given filetype.
|
|
|
|
------------------------------------------------------------------------------
|
|
5.2 Choosing the executable *syntastic-config-exec*
|
|
|
|
*'syntastic_<filetype>_<checker>_exec'*
|
|
The executable run by a checker is normally defined automatically, when the
|
|
checker is registered. You can however override it, by setting the variable
|
|
'g:syntastic_<filetype>_<checker>_exec': >
|
|
let g:syntastic_ruby_mri_exec = '~/bin/ruby2'
|
|
<
|
|
This variable has a local version, 'b:syntastic_<filetype>_<checker>_exec',
|
|
which takes precedence over the global one in the corresponding buffer.
|
|
|
|
*'b:syntastic_<checker>_exec'*
|
|
And there is also a local variable named 'b:syntastic_<checker>_exec', which
|
|
takes precedence over both 'b:syntastic_<filetype>_<checker>_exec' and
|
|
'g:syntastic_<filetype>_<checker>_exec' in the buffers where it is defined.
|
|
|
|
------------------------------------------------------------------------------
|
|
5.3 Configuring specific checkers *syntastic-config-makeprg*
|
|
|
|
Most checkers use the 'makeprgBuild()' function and provide many options by
|
|
default - in fact you can customise every part of the command that gets called.
|
|
|
|
*'syntastic_<filetype>_<checker>_<option>'*
|
|
Checkers that use 'makeprgBuild()' construct a 'makeprg' like this: >
|
|
let makeprg = self.makeprgBuild({
|
|
\ "exe": self.getExec(),
|
|
\ "args": "-a -b -c",
|
|
\ "post_args": "--more --args",
|
|
\ "tail": "2>/dev/null" })
|
|
<
|
|
The result is a 'makeprg' of the form: >
|
|
<exe> <args> <fname> <post_args> <tail>
|
|
<
|
|
All arguments above are optional, and can be overridden by setting global
|
|
variables 'g:syntastic_<filetype>_<checker-name>_<option-name>' - even
|
|
parameters not specified in the call to makeprgBuild(). These variables also
|
|
have local versions 'b:syntastic_<filetype>_<checker-name>_<option-name>',
|
|
which take precedence over the global ones in the corresponding buffers.
|
|
|
|
If one of these variables has a non-empty default and you want it to be empty,
|
|
you can set it to an empty string, e.g.: >
|
|
let g:syntastic_javascript_jslint_args = ""
|
|
<
|
|
*'syntastic_<filetype>_<checker>_exe'*
|
|
The 'exe' is normally the same as the 'exec' attribute described above, in
|
|
which case it may be omitted. However, you can use it to add environment
|
|
variables, or to change the way the checker is run. For example this setup
|
|
allows you to run PC-Lint under Wine emulation on Linux: >
|
|
let g:syntastic_c_pc_lint_exec = "wine"
|
|
let g:syntastic_c_pc_lint_exe = "wine c:/path/to/lint-nt.exe"
|
|
<
|
|
To override the args and the tail: >
|
|
let g:syntastic_c_pc_lint_args = "-w5 -Iz:/usr/include/linux"
|
|
let g:syntastic_c_pc_lint_tail = "2>/dev/null"
|
|
<
|
|
The general form of the override options is: >
|
|
syntastic_<filetype>_<checker>_<option-name>
|
|
<
|
|
For checkers that do not use the 'makeprgBuild()' function you will have to
|
|
look at the source code of the checker in question. If there are specific
|
|
options that can be set, these are usually documented in the wiki:
|
|
|
|
https://github.com/scrooloose/syntastic/wiki/Syntax-Checkers
|
|
|
|
*'syntastic_<filetype>_<checker>_quiet_messages'*
|
|
In the same vein, 'g:syntastic_<filetype>_<checker-name>_quiet_messages' can
|
|
be used to restrict message filters to messages produced by specific checkers.
|
|
Example: >
|
|
let g:syntastic_python_pylama_quiet_messages = {
|
|
\ "type": "style",
|
|
\ "regex": '\m\[C03\d\d\]' }
|
|
<
|
|
See |syntastic_quiet_messages| for the syntax.
|
|
|
|
------------------------------------------------------------------------------
|
|
5.4 Sorting errors *syntastic-config-sort*
|
|
|
|
*'syntastic_<filetype>_<checker>_sort'*
|
|
Syntastic may decide to group the errors produced by some checkers by file,
|
|
then sort them by line number, then by type, then by column number. If you'd
|
|
prefer to see the errors in the order in which they are output by the external
|
|
checker you can set the variable |'g:syntastic_<filetype>_<checker>_sort'| to 0.
|
|
|
|
Alternatively, if syntastic doesn't reorder the errors produced by a checker
|
|
but you'd like it to sort them, you can set the same variable to 1.
|
|
|
|
There is also a local version |'b:syntastic_<filetype>_<checker>_sort'| of
|
|
this variable, that takes precedence over it in the buffers where it is
|
|
defined.
|
|
|
|
For aggregated lists (see |syntastic-aggregating-errors|) these variables are
|
|
ignored if |syntastic_sort_aggregated_errors| is set (which is the default).
|
|
|
|

|
6. Notes *syntastic-notes*
|
|
|
|
------------------------------------------------------------------------------
|
|
6.1. Handling of composite filetypes *syntastic-composite*
|
|
|
|
Some Vim plugins use composite filetypes, such as "django.python" or
|
|
"handlebars.html". Normally, syntastic deals with this situation by splitting
|
|
the filetype in its simple components, and calling all checkers that apply.
|
|
If this behaviour is not desirable, you can disable it by mapping the
|
|
composite filetypes to a simple ones using |syntastic_filetype_map|, e.g.: >
|
|
let g:syntastic_filetype_map = { "handlebars.html": "handlebars" }
|
|
<
|
|
------------------------------------------------------------------------------
|
|
6.2 Editing files over network *syntastic-netrw*
|
|
|
|
The standard plugin |netrw| allows Vim to transparently edit files over
|
|
network and inside archives. Currently syntastic doesn't support this mode
|
|
of operation. It can only check files that can be accessed directly by local
|
|
checkers, without any translation or conversion.
|
|
|
|
------------------------------------------------------------------------------
|
|
6.3 The 'shellslash' option *syntastic-shellslash*
|
|
|
|
The 'shellslash' option is relevant only on Windows systems. This option
|
|
determines (among other things) the rules for quoting command lines, and there
|
|
is no easy way for syntastic to make sure its state is appropriate for your
|
|
shell. It should be turned off if your 'shell' (or |g:syntastic_shell|) is
|
|
"cmd.exe", and on for shells that expect an UNIX-like syntax, such as Cygwin's
|
|
"sh". Most checkers will stop working if 'shellslash' is set to the wrong
|
|
value.
|
|
|
|
------------------------------------------------------------------------------
|
|
6.4 Saving Vim sessions *syntastic-sessions*
|
|
|
|
If you use |:mksession| to save Vim sessions you should probably make sure to
|
|
remove option "blank" from 'sessionoptions': >
|
|
set sessionoptions-=blank
|
|
<
|
|
This will prevent |:mksession| from saving |syntastic-error-window| as empty
|
|
quickfix windows.
|
|
|
|
==============================================================================
|
|
7. Compatibility with other software *syntastic-compatibility*
|
|
|
|
------------------------------------------------------------------------------
|
|
7.1 The csh and tcsh shells *syntastic-csh*
|
|
|
|
The "csh" and "tcsh" shells are mostly compatible with syntastic. However,
|
|
some checkers assume Bourne shell syntax for redirecting "stderr". For this
|
|
reason, you should point |g:syntastic_shell| to a Bourne-compatible shell,
|
|
such as "zsh", "bash", "ksh", or even the original Bourne "sh": >
|
|
let g:syntastic_shell = "/bin/sh"
|
|
<
|
|
------------------------------------------------------------------------------
|
|
7.2. Eclim *syntastic-eclim*
|
|
|
|
Syntastic can be used together with "Eclim" (see http://eclim.org/). However,
|
|
by default Eclim disables syntastic's checks for the filetypes it supports, in
|
|
order to run its own validation. If you'd prefer to use Eclim but still run
|
|
syntastic's checks, set |g:EclimFileTypeValidate| to 0: >
|
|
let g:EclimFileTypeValidate = 0
|
|
<
|
|
It is also possible to re-enable syntastic checks only for some filetypes, and
|
|
run Eclim's validation for others. Please consult Eclim's documentation for
|
|
details.
|
|
|
|
------------------------------------------------------------------------------
|
|
7.3 The fish shell *syntastic-fish*
|
|
|
|
At the time of this writing the "fish" shell (see http://fishshell.com/)
|
|
doesn't support the standard UNIX syntax for file redirections, and thus it
|
|
can't be used together with syntastic. You can however set |g:syntastic_shell|
|
|
to a more traditional shell, such as "zsh", "bash", "ksh", or even the
|
|
original Bourne "sh": >
|
|
let g:syntastic_shell = "/bin/sh"
|
|
<
|
|
------------------------------------------------------------------------------
|
|
7.4. The fizsh shell *syntastic-fizsh*
|
|
|
|
Using syntastic with the "fizsh" shell (see https://github.com/zsh-users/fizsh)
|
|
is possible, but potentially problematic. In order to do it you'll need to set
|
|
'shellredir' like this: >
|
|
set shellredir=>%s\ 2>&1
|
|
<
|
|
Please keep in mind however that Vim can't take advantage of any of the
|
|
interactive features of "fizsh". Using a more traditional shell such as "zsh",
|
|
"bash", "ksh", or the original Bourne "sh" might be a better choice: >
|
|
let g:syntastic_shell = "/bin/sh"
|
|
<
|
|
------------------------------------------------------------------------------
|
|
7.5 flagship *syntastic-flagship*
|
|
|
|
The "flagship" Vim plugin (https://github.com/tpope/vim-flagship) has its
|
|
own mechanism of showing flags on the |'statusline'|. To allow "flagship"
|
|
to manage syntastic's statusline flag add the following |autocommand| to

your vimrc, rather than explicitly adding the flag to your |'statusline'| as
|
|
described in the |syntastic-statusline-flag| section above: >
|
|
autocmd User Flags call Hoist("window", "SyntasticStatuslineFlag")

7.6. powerline *syntastic-powerline*
|
|
|
|
The "powerline" Vim plugin (https://github.com/powerline/powerline) comes
|
|
packaged with a syntastic segment. To customize this segment create a file
|
|
~/.config/powerline/themes/vim/default.json, with a content like this: >
|
|
{
|
|
"segment_data" : {
|
|
"powerline.segments.vim.plugin.syntastic.syntastic" : {
|
|
"args" : {
|
|
"err_format" : "Err: {first_line} #{num} ",
|
|
"warn_format" : "Warn: {first_line} #{num} "
|
|
}
|
|
}
|
|
}
|
|
}
|
|
<
|
|
------------------------------------------------------------------------------
|
|
7.7. The PowerShell shell *syntastic-powershell*
|
|
|
|
At the time of this writing, syntastic is not compatible with using "Windows
|
|
PowerShell" (http://technet.microsoft.com/en-us/library/bb978526.aspx) as Vim's
|
|
'shell'. You may still run Vim from 'PowerShell', but you do have to point
|
|
Vim's 'shell' to a more traditional program, such as "cmd.exe": >
|
|
set shell=cmd.exe
|
|
<
|
|
------------------------------------------------------------------------------
|
|
7.8 python-mode *syntastic-pymode*
|
|
|
|
Syntastic can be used along with the "python-mode" Vim plugin (see
|
|
https://github.com/klen/python-mode). However, they both run syntax checks by
|
|
default when you save buffers to disk, and this is probably not what you want.
|
|
To avoid both plugins opening error windows, you can either set passive mode
|
|
for python in syntastic (see |syntastic_mode_map|), or disable lint checks in
|
|
"python-mode", by setting |pymode_lint_write| to 0. E.g.: >
|
|
let g:pymode_lint_write = 0
|
|
<
|
|
------------------------------------------------------------------------------
|
|
7.9. vim-auto-save *syntastic-vim-auto-save*
|
|
|
|
Syntastic can be used together with the "vim-auto-save" Vim plugin (see
|
|
https://github.com/907th/vim-auto-save). However, syntastic checks in active
|
|
mode only work with "vim-auto-save" version 0.1.7 or later.
|
|
|
|
------------------------------------------------------------------------------
|
|
7.10. vim-go *syntastic-vim-go*
|
|
|
|
The "vim-go" Vim plugin (https://github.com/fatih/vim-go) uses |quickfix|
|
|
lists, and thus doesn't conflict with syntastic (which uses |location-list|
|
|
lists). However, both "vim-go" and syntastic run syntax checks by default
|
|
when you save buffers to disk, and this can have confusing results. To
|
|
avoid both plugins opening error windows, you can either set passive
|
|
mode for go in syntastic (see |syntastic_mode_map|), or prevent "vim-go"
|
|
from showing a quickfix window when |g:go_fmt_command| fails, by setting
|
|
|g:go_fmt_fail_silently| to 1. E.g.: >
|
|
let g:go_fmt_fail_silently = 1
|
|
<
|
|
------------------------------------------------------------------------------
|
|
7.11. vim-virtualenv *syntastic-vim-virtualenv*
|
|
|
|
At the time of this writing, syntastic can't run checkers installed
|
|
in Python virtual environments activated by "vim-virtualenv" (see
|
|
https://github.com/jmcantrell/vim-virtualenv). This is a limitation of
|
|
"vim-virtualenv".
|
|
|
|
------------------------------------------------------------------------------
|
|
7.12 YouCompleteMe *syntastic-ycm*
|
|
|
|
Syntastic can be used together with the "YouCompleteMe" Vim plugin (see
|
|
http://valloric.github.io/YouCompleteMe/). However, by default "YouCompleteMe"
|
|
disables syntastic's checkers for the "c", "cpp", "objc", and "objcpp"
|
|
filetypes, in order to allow its own checkers to run. If you want to use YCM's
|
|
identifier completer but still run syntastic's checkers for those filetypes you
|
|
have to set |ycm_show_diagnostics_ui| to 0. E.g.: >
|
|
let g:ycm_show_diagnostics_ui = 0
|
|
<
|
|
------------------------------------------------------------------------------
|
|
7.13 The zsh shell and rvm *syntastic-zsh*
|
|
|
|
If you're running MacVim together with the "zsh" shell (http://www.zsh.org/)
|
|
and "rvm" (https://rvm.io/), you need to be aware that MacVim does not source
|
|
the .zshrc file, but will source a .zshenv file. Consequently you have to
|
|
either source the "rvm" scripts from within .zshenv, or just change your shell
|
|
to something else: >
|
|
set shell=/bin/sh
|
|
<
|
|
Of course, you'll have to make sure "rvm" still works in the new shell.
