Right now ghc-mod linter check temp file instead of current buffer,
which cause the problem that it can't detect cabal file and raise
missing package error.
To fix that we need to run ghc-mod check with actual path of the current
file and with ghc-mod option `--map-file` to redirect temp file source
code to actual one

The handler previously assumed there would be at least one entry in the
'files' array in the output JSON. It looks like this in the normal case:
"files":[{"path":"app/models/image.rb","offenses":[]}]
But if RuboCop's config excludes the specified input files, causing no
files to be linted, the output is emptier:
"files":[]
This change causes the handler to treat that case correctly, and also
exit early if the reported offense_count is zero.
* Move FindRailsRoot() to more general location
* Add rails_best_practices handler (resolves#655)
* Update documentation for rails_best_practices
Also add brakeman to *ale* documentation.
* rails_best_practices: allow overriding the executable
* rails_best_practices: format help correctly
* rails_best_practices: capture tool output on Windows
The real fix was not using absolute paths anymore (so not expanding with the `:p` option). The regex was correct and should at least include the `^` character to make sure the string starts with the given path/filename and not references the path/filename in some error description.
