1. Intro *syntastic-intro*
|
|
|
|
Syntastic is a syntax checking plugin that runs buffers through external syntax
|
|
checkers every time they are saved or 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.
|
|
|
|
The following features and functionality are provided:
|
|
* A statusline flag to alert you to syntax errors
|
|
* |signs| can be placed beside syntax errors, where a different sign is
|
|
used for errors and warnings.
|
|
* The :Error command is provided to open a |location-list| containing
|
|
the syntax errors in the current buffer
|
|
|
|
==============================================================================
|
|
2. Functionality provided *syntastic-functionality*
|
|
|
|
|
|
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 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. 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 tell syntastic to automatically open the location list (see
|
|
|syntastic-error-window|) when a buffer has errors: >
|
|
let g:syntastic_auto_loc_list=1
|
|
<
|
|
==============================================================================
|
|
4. 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. 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.
