update makeprg builder:
* it now accepts `fname`, `tail`, and `post_args` params.
* add some doc above syntastic#makeprg#build
* update a bunch of checkers to use the new params
Still have quite a few checkers that arent using makeprg#build.
Including all c* and a few other c-like checkers. And PHP.
Not to worried about c* as these checkers are complicated and probably
justify having their own logic to build makeprgs.
Make all the easy updates. There are still quite a few to do, but in
doing these ones I can see that syntastic#makeprg#build() needs to
accept a few more options. Namely:
* "postargs" that appear after the filename
* "tail" that appears after everything - used for things like
redirecting output and piping to grep/sed/etc
* the filename itself - only the java checkers needed this since they
specify the directory of the file to check as well
There are still a few other things to do as well:
* remove the options from the checkers that are now provided by
syntastic#makeprg#build implicitly - i.e. the checker exe and args.
* also, we need to doc the above implicit checker options
Using lessc to check a less file results in a NameError if the file references a
variable defined in a file that inherits it. This commit adds a new linter that
just calls the less parser instead. The variable g:syntastic_less_use_less_lint
should be set to use the linter over lessc.
* remove some unneeded escaping of spaces and colons from the 1.2
errorformat
* split the pre and post 1.2 errorformats up and comment them for future
clarity
I installed the latest version of lessc and they have modified their
output slightly. Update the errorformat for this.
Also, they new output is colorized by default. So I have added an option
to specify args to the checker that currently defaults to "--no-color".
This means that if people want to use an older version of lessc, they
will need to reset this option to an empty string.
Many of the syntax checkers were setting the 'bufnr' key for each
error manually and one was setting 'text' if it didnt exist too.
Add the 'defaults' option to SyntasticMake to set default values in the
returned error list - it only sets values if they are empty.
