Add python checker that uses python itself The advantage to this is that no 3rd party modules are required. People new to Python probably won't have flake8/pyflakes/pylint installed.

Registry cleanup, stage 1. Make SyntaxCheckers_*_GetLocList() dictionary functions. Pass a reference to the current checker to syntastic#makeprg#build(). Add an optional 'redirect' argument to CreateAndRegisterChecker(). Change the sh checker to use the new dictionary functions. Add a new registry method getLocListRaw() (needed for the sh checker). 2013-10-28 07:53:33 -04:00			`function! SyntaxCheckers_python_python_GetLocList() dict`
Rework of the python checker. 2013-04-12 06:14:07 -04:00			`let fname = "'" . escape(expand('%'), "\\'") . "'"`
Make syntastic#makeprg#build() aware of filetypes. Fixes #667. 2013-05-31 14:05:45 -04:00
Registry cleanup, stage 3. Make syntastic#makeprg#build() a dictionary function. Remove the mandatory checker argument to syntastic#makeprg#build(). 2013-11-01 05:51:47 -04:00			`let makeprg = self.makeprgBuild({`

refactor how we represent and store checkers using python as a demo Add 2 classes: SyntasticChecker and SyntasticRegistry. SyntasticChecker represents a checker. It holds funcrefs to the checker func, the highlight regex func and a new `isAvailable()` func (that essentially just checks if the checker exe is installed) SyntasticRegistry is responsible for: * loading checkers * storing checkers * fetching the checkers to use according to availability and the users settings Motivation/benefits: * in the current system only one checker can be loaded per filetype * syntax checkers cant be "chained" together * the system is hard to add features to since fundamental concepts like syntax checkers and location lists arent represented explicitly Things left to do: * add a call to g:SyntasticRegistry.CreateAndRegisterChecker() to all checkers * add an `isAvailable` function to all checkers * move all checkers into `syntax_checkers/filetype/checkername.vim` - g:SyntasticRegistry assumes this layout, and its a good idea anyway for consistency and it makes it easier for users to add their own checkers Things to do after all of the above: * add a LocationList class and move all the filtering functions onto it * possibly add an Error class that wraps up each item in a loc list Random notes: * with the new system you can select the checkers to use with e.g. `let g:syntastic_python_checkers=['flake8', 'pylint']` This will try flake8 first, and if no errors are detected it will move onto pylint. 2013-01-23 19:01:30 -05:00
