* 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
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 ALEInfo command to get list of available/enabled linters for current filetype
* Add Vader tests for ALEInfo command
* Fix ALEInfo tests breaking CI by echoing too much output to screen
* Speculative change to Makefile which seems to fix test hanging problem locally.
* Fix Vader tests to not require a TTY
* Add option to open loclist/quicklist when there are errors
I copied PR #137, and tries to complete it by correcting some issues and
adding vader tests.
About tests, first time with vader, can you give some feedback if there
are what you expected in PR #137.
* Remove old code + fix indent issue
* add g:ale_keep_list_window_open option
* Correct bug with keep open option
* Add comment into vader file
* Fix errors for Travis CI build
