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 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. At the time of this writing, syntax checking plugins exist for c, coffee, cpp, css, cucumber, cuda, docbk, erlang, eruby, fortran, go, haml, haskell, html, javascript, less, lua, matlab, perl, php, puppet, python, ruby, sass/scss, sh, tcl, tex, vala, xhtml, xml, xslt, zpt Take a look in the syntax_checkers directory for the most up to date list. 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* Syntax checking can be done automatically or on demand (see |'syntastic_mode_map'| 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 configurable statusline flag * Lines with errors can have |signs| placed beside them - where a different sign is used for errors and warnings. * A |location-list| can be displayed with error messages for erroneous buffers. * Offending parts of lines can be highlighted (this functionality is only provided by some syntax checkers). * Balloons (if compiled in) can be used to display error messages for erroneous lines when hovering the mouse over them. 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 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. ------------------------------------------------------------------------------ 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* :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. Useful in passive mode, or if the current filetype is set to passive. See |'syntastic_mode_map'| for more info. ============================================================================== 4. Options *syntastic-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_echo_current_error'* Default: 1 If enabled, syntastic will error message 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_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_auto_jump'* Default: 0 Enable this option if you want the cursor to jump to the first detected error when saving or opening a file: > let g:syntastic_auto_jump=1 < *'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_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_warnings'* Use this option if you only care about syntax errors, not warnings. When set, this option has the following effects: * 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_stl_format'* Default: [Syntax: line:%F (%t)] Use this option to control what the syntastic statusline text contains. Several magic flags are availble 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 cant 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] < ============================================================================== 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/.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__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. ============================================================================== 6.
