* Adds options to foodcritic linter
Adds a way to pass command line options to the foodcritic command and
documentation about it.
* Creates a simple test for foodcritic command callback
This test simply runs the GetCommand function for the foodcritic linter
and feeds it with some test variables to assert the command line is
being created/escaped correctly.
* Makes foodcritic linter use a command callback
Following review comments, changes the foodcritic linter to use a
`GetCommand` callback for the `command_callback` linter option.
Makes sure that `~` are escaped: flags on foodcritic command line are
negated by adding a `~` in front of the specific cop name:
```
foodcritic -t ~FC011
```
But the way the commands are executed cause foodcritic to fail (since
tilde is recognized as home directory).
* Fixes the doc to include new variables
* Remove 'col' from linters where it is hardcoded to 1
When 'col' is 1, the first column will get highlighted for no reason. It
should be 0 (which is the default).
In the scalac linter there was also a check about the outcome of
`stridx`. It would set l:col to 0 if it was -1, and then it uses
`'col': l:col + 1` to convert the outcome of `stridx` to the actual
column number. This will make 'col' equals 1 when there is no match. We
can remove the check because `-1 + 1 = 0`.
* Remove outdated comments about vcol
vcol was added as a default, and the loclists that follow these comments
do not contain 'vcol' anymore
* Fix problems with nim check
- Multi file errors are not shown in the same buffer
- Fixes parsing of error type that contain ':'
* Remove redundant fnameescape
In particular, if we're working with a leex (.xrl) or yecc (.yrl) source
file, erlc would otherwise generate the corresponding .erl file in the
current directory (often the project root), which is generally not what
we want.
Unconditionally writing erlc output to a temporary directory also
matches Flycheck's behavior.
* PHP: Fix column matching for unexpected single quotes
Unexpected single quotes resulted in an empty match, because PHP
surrounds the errors with quotes, and we check for the next quote to be
the ending delimiter.
For example: an unexpected string 'foo' would be presented as
`unexpected ''foo''`, and then the match would be `''`. The inner part
of that match is an empty string.
This adds a check for the keyword "expecting". Any quote after
"expecting" won't be matched, so we can use greedy matching instead of
non-greedy.
* PHP: Use "very magic"
The pattern started to get unreadable
Also replaced non-greedy matching (`\{-}`) by greedy matching, because
we don't need to match non-greedily anymore and it reads a little nicer.
* PHP: Add tests for column matches
And with that, also a test for unexpected single quotes.
* Fix Credo's line-matching pattern
In d3e7d3d5, the line matching pattern was changed to handle filenames
other than `stdin`. Unfortunately, this broke the pattern's ability to
reliably extract both line and column numbers because the latter is an
optional match and the filename portion was very greedy. This resulted
in line numbers being discarded (treated as part of the filename) and
column numbers being interpreted as line numbers.
This change simplifies the pattern to only anchor on the line's suffix,
ignoring the filename portion entirely.
Alternatively, we could use vim's `\f` ("file name characters") class,
but that could still run into problems when `:`'s naturally appear in
the filename.
* Add a Vader test case for the Credo handler
This adds support for the hdevtools haskell linter
https://github.com/hdevtools/hdevtools
The output for hdevtools is near identical to the ghc output so this
also extracts the ghc handler into the handle file and adds tests
* Add testing for previous major release of ghc
