Pyflakes
==========
This is just a manual dump of the vim pyflakes plugin from:
http://www.vim.org/scripts/script.php?script_id=2441
The purpose is to try to make this compatible with pathogen plugin. So creating
the dir structure and hopefully this means we can just keep the norm and git
clone the repo into the bundle directory and things will load up magically.

pyflakes-vim
============
A Vim plugin for checking Python code on the fly.
PyFlakes catches common Python errors like mistyping a variable name or
accessing a local before it is bound, and also gives warnings for things like
unused imports.
pyflakes-vim uses the output from PyFlakes to highlight errors in your code.
To locate errors quickly, use quickfix_ commands like :cc.
Make sure to check vim.org_ for the latest updates.
.. _pyflakes.vim: http://www.vim.org/scripts/script.php?script_id=2441
.. _vim.org: http://www.vim.org/scripts/script.php?script_id=2441
.. _quickfix: http://vimdoc.sourceforge.net/htmldoc/quickfix.html#quickfix
Quick Installation
------------------
1. Make sure your ``.vimrc`` has::
filetype on " enables filetype detection
filetype plugin on " enables filetype specific plugins
2. Download the latest release_.
3. Unzip ``pyflakes.vim`` and the ``pyflakes`` directory into
``~/.vim/ftplugin/python`` (or somewhere similar on your
`runtime path`_ that will be sourced for Python files).
.. _release: http://www.vim.org/scripts/script.php?script_id=2441
.. _runtime path: http://vimdoc.sourceforge.net/htmldoc/options.html#'runtimepath'
Installation
------------
If you downloaded this from vim.org_, then just drop the contents of the zip
file into ``~/.vim/ftplugin/python``.
Otherwise, if you're running "from source," you'll need PyFlakes on your
PYTHONPATH somewhere. I recommend getting my PyFlakes_ fork, which retains
column number information and has therfore has more specific error locations.
.. _vim.org: http://www.vim.org/scripts/script.php?script_id=2441
.. _PyFlakes: http://github.com/kevinw/pyflakes
Hacking
-------
::
git clone git://github.com/kevinw/pyflakes-vim.git
cd pyflakes-vim
git clone git://github.com/kevinw/pyflakes.git
Options
-------
Set this option to you vimrc file to disable quickfix support::
let g:pyflakes_use_quickfix = 0
The value is set to 1 by default.
TODO
----
* signs_ support (show warning and error icons to left of the buffer area)
* configuration variables
* parse or intercept useful output from the warnings module
.. _signs: http://www.vim.org/htmldoc/sign.html
Changelog
---------
Please see http://www.vim.org/scripts/script.php?script_id=2441 for a history of
all changes.

0.4.0 (2009-11-25):
- Fix reporting for certain SyntaxErrors which lack line number
information.
- Check for syntax errors more rigorously.
- Support checking names used with the class decorator syntax in versions
of Python which have it.
- Detect local variables which are bound but never used.
- Handle permission errors when trying to read source files.
- Handle problems with the encoding of source files.
- Support importing dotted names so as not to incorrectly report them as
redefined unused names.
- Support all forms of the with statement.
- Consider static `__all__` definitions and avoid reporting unused names
if the names are listed there.
- Fix incorrect checking of class names with respect to the names of their
bases in the class statement.
- Support the `__path__` global in `__init__.py`.
0.3.0 (2009-01-30):
- Display more informative SyntaxError messages.
- Don't hang flymake with unmatched triple quotes (only report a single
line of source for a multiline syntax error).
- Recognize __builtins__ as a defined name.
- Improve pyflakes support for python versions 2.3-2.5
- Support for if-else expressions and with statements.
- Warn instead of error on non-existant file paths.
- Check for __future__ imports after other statements.
- Add reporting for some types of import shadowing.
- Improve reporting of unbound locals

pyflakes
========
This version of PyFlakes_ has been improved to use Python's newer ``ast``
module, instead of ``compiler``. So code checking happens faster, and will stay
up to date with new language changes.
.. _PyFlakes: http://http://www.divmod.org/trac/wiki/DivmodPyflakes
TODO
----
Importing several modules from the same package results in unnecessary warnings:
::
import a.b
import a.c # Redefinition of unused "a" from line 1
The following construct for defining a function differently depending on some
condition results in a redefinition warning:
::
if some_condition:
def foo(): do_foo()
else:
def foo(): do_bar() # redefinition of function 'foo' from line 2

ast
~~~
The `ast` module helps Python applications to process trees of the Python
abstract syntax grammar. The abstract syntax itself might change with
each Python release; this module helps to find out programmatically what
the current grammar looks like and allows modifications of it.
An abstract syntax tree can be generated by passing `ast.PyCF_ONLY_AST` as
a flag to the `compile()` builtin function or by using the `parse()`
function from this module. The result will be a tree of objects whose
classes all inherit from `ast.AST`.
A modified abstract syntax tree can be compiled into a Python code object
using the built-in `compile()` function.
Additionally various helper functions are provided that make working with
the trees simpler. The main intention of the helper functions and this
module in general is to provide an easy to use interface for libraries
that work tightly with the python syntax (template engines for example).

value=Name(id='data', ctx=Load()),
slice=Index(value=Str(s=node.id)),

Keep in mind that if the node you're operating on has child nodes you must
either transform the child nodes yourself or call the :meth:`generic_visit`
method for the node first.
For nodes that were part of a collection of statements (that applies to all
statement nodes), the visitor may also return a list of nodes rather than
just a single node.
Usually you use the transformer like this::
node = YourTransformer().visit(node)

# Bug reports / Github issues
When reporting a bug make sure you search the existing github issues for the
same/similar issues. If you find one, feel free to add a `+1` comment with any
additional information that may help us solve the issue.
When creating a new issue be sure to state the following:
* Steps to reproduce the bug.
* The version of vim you are using.
* The version of syntastic you are using.
For syntax checker bugs also state the version of the checker executable that you are using.
# Submitting a patch
* Fork the repo on github
* Make a [topic branch](https://github.com/dchelimsky/rspec/wiki/Topic-Branches#using-topic-branches-when-contributing-patches) and start hacking
* Submit a pull request based off your topic branch
Small focused patches are preferred.
Large changes to the code should be discussed with the core team first. Create an issue and explain your plan and see what we say.
# General style notes
Following the coding conventions/styles used in the syntastic core:
* Use 4 space indents.
* Don't use abbreviated keywords - e.g. use `endfunction`, not `endfun` (there's always room for more fun!).
* Don't use `l:` prefixes for variables unless actually required (i.e. almost never).
* Code for maintainability. We would rather a function be a couple of lines longer and have (for example) some [explaining variables](http://www.refactoring.com/catalog/introduceExplainingVariable.html) to aid readability.
# Syntax checker style notes
The preferred style for error format strings is one "clause" per line. E.g.
(from the coffeelint checker):
```viml
let errorformat = '%E%f:%l:%c: %trror: %m,' .
\ 'Syntax%trror: In %f\, %m on line %l,' .
\ '%EError: In %f\, Parse error on line %l: %m,' .
\ '%EError: In %f\, %m on line %l,' .
\ '%W%f(%l): lint warning: %m,' .
\ '%W%f(%l): warning: %m,' .
\ '%E%f(%l): SyntaxError: %m,' .
\ '%-Z%p^,' .
\ '%-G%.%#'
```

## 1\. Introduction
Syntastic is a syntax checking plugin for Vim that runs files through external
syntax checkers and displays any resulting errors to the user. This can be done
on demand, or automatically as files are saved. 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.
At the time of this writing, syntax checking plugins exist for ActionScript,
Ada, AppleScript, AsciiDoc, ASM, BEMHTML, Bourne shell, C, C++, C#, Chef,
CoffeeScript, Coco, Coq, CSS, Cucumber, CUDA, D, Dart, DocBook, Dust, Elixir,
Erlang, eRuby, Fortran, Gentoo metadata, GLSL, Go, Haml, Haskell, Haxe,
Handlebars, HSS, HTML, Java, JavaScript, JSON, LESS, Lex, Limbo, LISP,
LLVM intermediate language, Lua, MATLAB, NASM, Objective-C, Objective-C++,
OCaml, Perl, Perl POD, PHP, gettext Portable Object, Puppet, Python, Racket,
reStructuredText, Ruby, Rust, SASS/SCSS, Scala, Slim, Tcl, TeX, Texinfo, Twig,
TypeScript, Vala, Verilog, VHDL, VimL, xHtml, XML, XSLT, YACC, YAML, z80, Zope
page templates, zsh.
Below is a screenshot showing the methods that Syntastic uses to display syntax
errors. Note that, in practise, you will only have a subset of these methods
enabled.
![Screenshot 1][0]
1. Errors are loaded into the location list for the corresponding window.
2. When the cursor is on a line containing an error, the error message is echoed in the command window.
3. Signs are placed beside lines with errors - note that warnings are displayed in a different color.
4. There is a configurable statusline flag you can include in your statusline config.
5. Hover the mouse over a line containing an error and the error message is displayed as a balloon.
6. (not shown) Highlighting errors with syntax highlighting. Erroneous parts of lines can be highlighted.
<a name="installation"></a>
## 2\. Installation
Installing syntastic is easy but first you need to have the pathogen plugin installed. If you already
have pathogen working then skip Step 1 and go to Step 2.
<a name="step1"></a>
### 2.1\. Step 1: Install pathogen.vim
First I'll show you how to install tpope's [pathogen.vim][1] so that it's
easy to install syntastic. Do this in your Terminal so that you get the
pathogen.vim file and the directories it needs:
mkdir -p ~/.vim/autoload ~/.vim/bundle; \
curl -so ~/.vim/autoload/pathogen.vim \
https://raw.github.com/tpope/vim-pathogen/master/autoload/pathogen.vim
Next you *need to add this* to your ~/.vimrc:
execute pathogen#infect()
<a name="step2"></a>
### 2.2\. Step 2: Install syntastic as a pathogen bundle
You now have pathogen installed and can put syntastic into ~/.vim/bundle like this:
cd ~/.vim/bundle
git clone https://github.com/scrooloose/syntastic.git
Quit vim and start it back up to reload it, then type:
:Helptags
If you get an error when you do this, then you probably didn't install pathogen right. Go back to
step 1 and make sure you did the following:
1. Created both the ~/.vim/autoload and ~/.vim/bundle directories.
2. Added the "call pathogen#infect()" line to your ~/.vimrc file
3. Did the git clone of syntastic inside ~/.vim/bundle
4. Have permissions to access all of these directories.
<a name="faq"></a>
## 3\. FAQ
__Q. I installed syntastic but it isn't reporting any errors...__
A. The most likely reason is that none of the syntax checkers that it requires
is installed. For example: python requires either `flake8`, `pyflakes`
or `pylint` to be installed and in `$PATH`. To see which executables are
supported, just look in `syntax_checkers/<filetype>/*.vim`. Note that aliases
do not work; the actual executable must be available in your `$PATH`. Symbolic
links are okay. You can see syntastic's idea of available checkers by running
`:SyntasticInfo`.
Another reason it could fail is that either the command line options or the
error output for a syntax checker may have changed. In this case, make sure you
have the latest version of the syntax checker installed. If it still fails then
create an issue - or better yet, create a pull request.
__Q. Recently some of my syntax checker options have stopped working...__
A. The options are still there, they have just been renamed. Recently,
almost all syntax checkers were refactored to use the new `makeprgBuild()`
function. This made a lot of the old explicit options redundant - as they are
now implied. The new implied options usually have slightly different names to
the old options.
e.g. Previously there was `g:syntastic_phpcs_conf`, now you must use
`g:syntastic_php_phpcs_args`. This completely overrides the arguments of
the checker, including any defaults, so you may need to look up the default
arguments of the checker and add these in.
See `:help syntastic-checker-options` for more information.
__Q. I run a checker and the location list is not updated...__
A. By default, the location list is changed only when you run the `:Errors`
command, in order to minimise conflicts with other plugins. If you want the
location list to always be updated when you run the checkers, add this line to
your vimrc:
```vim
let g:syntastic_always_populate_loc_list=1
```
__Q. How can I pass additional arguments to a checker?__
A. Almost all syntax checkers use the `makeprgBuild()` function. Those checkers
that do can be configured using global variables. The general form of the
global args variables are:
```vim
syntastic_<filetype>_<subchecker>_args
```
So, If you wanted to pass "--my --args --here" to the ruby mri checker you
would add this line to your vimrc:
```vim
let g:syntastic_ruby_mri_args="--my --args --here"
```
See `:help syntastic-checker-options` for more information.
__Q. Syntastic supports several checkers for my filetype - how do I tell it
which one(s) to use?__
A. Stick a line like this in your vimrc:
```vim
let g:syntastic_<filetype>_checkers=['<checker-name>']
```
To see the list of checkers for your filetype, look in
`syntax_checkers/<filetype>/`.
e.g. Python has the following checkers: `flake8`, `pyflakes`, `pylint` and a
native `python` checker.
To tell syntastic to use `pylint`, you would use this setting:
```vim
let g:syntastic_python_checkers=['pylint']
```
Some filetypes, like PHP, have style checkers as well as syntax checkers. These
can be chained together like this:
```vim
let g:syntastic_php_checkers=['php', 'phpcs', 'phpmd']
```
This is telling syntastic to run the `php` checker first, and if no errors are
found, run `phpcs`, and then `phpmd`.
__Q. How can I jump between the different errors without using the location
list at the bottom of the window?__
A. Vim provides several built in commands for this. See `:help :lnext` and
`:help :lprev`.
If you use these commands a lot then you may want to add shortcut mappings to
your vimrc, or install something like [unimpaired][2], which provides such
mappings (among other things).
__Q. A syntax checker is giving me unwanted/strange style tips?__
A. Some filetypes (e.g. php) have style checkers as well as syntax
checkers. You can usually configure the options that are passed to the style
checkers, or just disable them. Take a look at the [wiki][3] to see what
options are available.
__Q. The error window is closed automatically when I :quit the current buffer
but not when I :bdelete it?__
A. There is no safe way to handle that situation automatically, but you can
work around it:
```vim
nnoremap <silent> <C-d> :lclose<CR>:bdelete<CR>
cabbrev <silent> bd lclose\|bdelete
```

The preferred place for posting suggestions, reporting bugs, and general
discussions related to syntastic is the [issue tracker at GitHub][4]. There
are also a [google group][5], and a [syntastic tag at StackOverflow][6].
Syntastic aims to provide a common interface to syntax checkers for as many
languages as possible. For particular languages, there are, of course, other
plugins that provide more functionality than syntastic. You might want to take
a look at [jedi-vim][7], [python-mode][8], or [YouCompleteMe][9].

==============================================================================
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 checkers available for the current filetype with the
|:SyntasticInfo| command.
If you want to override the configured list of checkers for a filetype then
see |syntastic-checker-options| for details. You can also change the arguments
passed to a specific checker as well.
Use |:SyntasticCheck| to manually check right now. Use |:SyntasticToggleMode|
to switch between active (checking on writting the buffer) and passive (manual)
checking.
==============================================================================
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-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 *:Errors* *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.
------------------------------------------------------------------------------
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
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 these labels by unsetting '|syntastic_id_checkers|'.
------------------------------------------------------------------------------
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 *:SyntasticErrors*
When errors have been detected, use this command to pop up the |location-list|
and display the error messages.
: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_echo_current_error'*
Default: 1
If enabled, syntastic will echo the error associated with the current line to
the command window. If multiple errors are found, the first will be used. >
let g:syntastic_echo_current_error = 1
<
*'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. >
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
<
*'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 = { 'latex': '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 all filetypes in the "active_filetypes" array. In active mode,
automatic checks are not done for any filetypes in the
"passive_filetypes" array.
At runtime, the |:SyntasticToggleMode| command can be used to switch between
active and passive mode.
If any of "mode", "active_filetypes", or "passive_filetypes" are not specified
then they will default to their default value as above.
*'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": "warnings",
\ "type": "style",
\ "regex": '\m\[C03\d\d\]',
\ "file": ['\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 can omit adding the brackets (e.g. you can write "style" instead of
["style"]).
"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 filename the error refers to, as a case
sensitive |regular-expression|.
There are also checker-specific variants of this option, providing finer
control. They are named |'syntastic_<filetype>_<checker>_quiet_messages'|.
*'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]
<
*'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_debug'*
Default: 0
Set this to the sum of one or more of the following flags to enable
debugging:
1 - trace checker calls
2 - dump location lists
4 - trace notifiers
8 - trace autocommands
16 - dump options
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'
<
==============================================================================
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>_<subchecker>_exec'*
The executable used by a checker is normally defined automatically, when the
checkers is registered. You can however override it by setting the variable
'g:syntastic_<filetype>_<subchecker>_exec': >
let g:syntastic_ruby_mri_exec = '~/bin/ruby2'
<
------------------------------------------------------------------------------
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>_<subchecker>_<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': '> /tmp/output' })
<
The result is a 'makeprg' of the form: >
<exe> <args> <filename> <post_args> <tail>
<
*'syntastic_<filetype>_<subchecker>_exe'*
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().
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 additional parameters, e.g. to tell the mri checker to use KANJI
encoding you could do something like this: >
let g:syntastic_ruby_mri_exe = 'RUBYOPT="-Ke" ruby'
<
To override the args and the tail: >
let g:syntastic_ruby_mri_args = "--my --args --here"
let g:syntastic_ruby_mri_tail = "> /tmp/my-output-file-biatch"
<
The general form of the override options is: >
syntastic_<filetype>_<subchecker>_<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.
==============================================================================
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 Interaction with 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
<
------------------------------------------------------------------------------
6.3 Interaction with 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 don't need to change your login
shell to address this problem, but you do have to point Vim's 'shell' to a more
traditional shell, such as 'zsh', 'bash', 'ksh', or even the original Bourne
'sh': >
set shell=bash
<
------------------------------------------------------------------------------
6.4. Using syntastic with 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: >
set shell=zsh
<

" History: 0.1.0 - working, but it will run the script everytime to check

" 0.2.0 - switch to osacompile, it gives less errors compared

"
" 0.2.1 - remove g:syntastic_applescript_tempfile. use
