1. Intro *syntastic-intro*
|
|
|
|
Syntastic is a syntax checking plugin that runs buffers through external syntax
|
|
checkers as they 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 script
|
|
(i.e. syntastic.vim). 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. Currently, syntax checking plugins exist for c,
|
|
coffee, cpp, cucumber, eruby, haml, haskell, html, javascript, lua, perl, php,
|
|
python, ruby, sass, sh, tex and xhtml.
|
|
|
|
NOTE: This list is subject to change without notice. Please check the
|
|
syntax_checkers directory for a reliable list of syntax checkers.
|
|
|
|
If your language is not supported then see |syntastic-syntax-checkers| for
|
|
details on how to implement a syntax checking plugin, and be sure to send me a
|
|
patch ;-)
|
|
|
|
This plugin is currently only recommended for *nix users. It is functional on
|
|
Windows, but since the syntax checking plugins shell out, the command window
|
|
briefly appears whenever one is executed.
|
|
|
|
|
|
==============================================================================
|
|
2. Functionality provided *syntastic-functionality*
|
|
|
|
By default, the script does nothing. The following functionality is provided
|
|
and must be enabled/activated as indicated (see the sections below for more
|
|
in-depth descriptions):
|
|
* A statusline flag appears when syntax errors are detected
|
|
* |signs| are placed beside lines with syntax errors, where a different
|
|
sign is used for errors and warnings.
|
|
* The :Errors command is provided to open a |location-list| for
|
|
the syntax errors in the current buffer
|
|
|
|
Note: This functionality is only available if a syntax checker plugin is
|
|
present for the filetype of the buffer in question. See
|
|
|syntastic-syntax-checkers| for details.
|
|
|
|
------------------------------------------------------------------------------
|
|
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, the following will be displayed on your
|
|
statusline: >
|
|
[syntax:X(Y)]
|
|
<
|
|
Where X is the line number of the first error and Y is the total number of
|
|
errors. Note that "(Y)" only appears if there is more than one error.
|
|
|
|
------------------------------------------------------------------------------
|
|
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.
|
|
|
|
------------------------------------------------------------------------------
|
|
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.
|
|
|
|
|
|
==============================================================================
|
|
3. Commands *syntastic-commands*
|
|
|
|
:SyntasticDisable [filetype] *:SyntasticDisable*
|
|
Disables syntax checking for the the given filetype (if specified), or the
|
|
current filetype.
|
|
|
|
:SyntasticEnable [filetype] *:SyntasticEnable*
|
|
Enables syntax checking for the the given filetype (if specified), or the
|
|
current filetype.
|
|
|
|
|
|
==============================================================================
|
|
4. Options *syntastic-options*
|
|
|
|
*'syntastic_enable_signs'*
|
|
Use this option to tell syntastic to use the |:sign| interface to mark syntax
|
|
errors: >
|
|
let g:syntastic_enable_signs=1
|
|
<
|
|
|
|
*'syntastic_auto_loc_list'*
|
|
Use this option to tell syntastic to automatically open the |location-list|
|
|
(see |syntastic-error-window|) when a buffer has errors: >
|
|
let g:syntastic_auto_loc_list=1
|
|
<
|
|
The location list is also closed again when there are no errors.
|
|
|
|
*'syntastic_quiet_warnings'*
|
|
|
|
Use this option if you only care about syntax errors, not warnings. When set,
|
|
this option has the following effects:
|
|
* the statusline flag only counts syntax errors
|
|
* no |signs| appear unless there is at least one error, whereupon both
|
|
errors and warnings are displayed
|
|
* the |'syntastic_auto_loc_list'| option only pops up the error window if
|
|
there's at least one error, whereupon both errors and warnings are
|
|
displayed
|
|
>
|
|
let g:syntastic_quiet_warnings=1
|
|
<
|
|
|
|
*'syntastic_disabled_filetypes'*
|
|
Use this option to disable syntax checking on selected filetypes by default.
|
|
Should be set to a list of filetypes, e.g. >
|
|
let g:syntastic_disabled_filetypes = ['ruby', 'php']
|
|
<
|
|
Syntax checking can be enabled again via |:SyntasticEnable|.
|
|
|
|
==============================================================================
|
|
5. Writing syntax checkers *syntastic-syntax-checkers*
|
|
|
|
|
|
A syntax checker plugin is really nothing more than a single function. You
|
|
should define them in ~/.vim/syntax_checkers/<filetype>.vim, but this is
|
|
purely for convenience; Syntastic doesn't actually care where these functions
|
|
are defined.
|
|
|
|
A syntax checker plugin must define a function of the form:
|
|
>
|
|
SyntaxCheckers_<filetype>_GetLocList()
|
|
<
|
|
The output of this function must be of the same format as that returned by
|
|
the |getloclist()| function. See |getloclist()| and |getqflist()| for
|
|
details.
|
|
|
|
To achieve this, the function should call |SyntasticMake()| or shell out to a
|
|
syntax checker, parse the output and munge it into the format.
|
|
|
|
There are several syntax checker plugins provided with this plugin. The ruby
|
|
one is a good example of |SyntasticMake()|, while the haml one is a good
|
|
example of how to create the data structure manually.
|
|
|
|
|
|
SyntasticMake({options}) *SyntasticMake()*
|
|
{options} must be a dictionary. It can contain "makeprg" and "errorformat"
|
|
as keys (both optional).
|
|
|
|
SyntasticMake will run |:lmake| with the given |'makeprg'| and
|
|
|'errorformat'| (using the current settings if none are supplied). It will
|
|
store the resulting error list and use it to provide all of the
|
|
|syntastic-functionality|. The previous makeprg and errorformat settings
|
|
will then be restored, as well as the location list for the window. From
|
|
the user's perspective, it will be as though |:lmake| was never run.
|
|
|
|
Note that the given "makeprg" and "errorformat" will be set using |:let-&|,
|
|
so you should not escape spaces.
