(1) Checkers now have an _exec attribute, and an accessor getExec().
(2) CreateAndRegisterChecker() initializes _exec from an optional argument
'exec'. If this argument is missing, 'name' is used instead.
(3) Functions SyntaxCheckers_*_IsAvailable() are now dictionary functions.
(4) Functions SyntaxCheckers_*_IsAvailable() are now optional. When
they are missing, they are assumed to return executable(expand(self.getExec())).
(5) Argument 'exe' of function syntastic#makeprg#build() is now optional.
If this argument is missing, expand(self.getExec()) is used to set checker
executables.
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).
The errorformat for the RuboCop checker was missing the capture group
for the column number of the error/warning, which resulted in the
location list attempting to jump to 'filename.rb:80', which would
attempt to open a new file.
The solution was to add the "%c" to capture the column number of the
error.
RVM does not always provide an executable for specific ruby version
that is loaded (the "system" version).
RVM, or whatever else the user uses, should always setup "ruby" to point
to the correct version so this can always be used.
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
Query RVM for the version of ruby that should be used to do the syntax
check.
This wont work if the user has different versions of ruby for different
directories (e.g. if they are using a project rvmrc) as it will only a
single ruby version per vim instance.
I think this should satisfy almost everyone though, so we can wait for
feedback before doing anything more hardcore.
