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
* Use rubocop's JSON output format (resolves#339)
Rubocop's emacs formatter seems to have changed format in some
not-so-ancient version. The JSON formatter should provide a more stable
interface than parsing lines with a regex.
The JSON formatter was introduced in mid-2013, so it should be safe to
assume available in any reasonably-modern environment. The oldest
currently-supported version of ruby (according to ruby-lang.org) was
not supported by rubocop until 2014.
* Rubocop: Use global function for GetType
* Rubocop: Use scope prefix in GetType
* Rubocop: Update command_callback test
* Rubocop: add end_col to Handle
* Added ruby mri linter
* Added to the list of supported linters
* Async and now with 4 spaces
* Vader tests for ruby
* Match style choices
* Vader test for the Ruby handler now works and passes
* 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* Remove outdated comments about vcol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
In my previous change, I updated the Rubocop linter to pass the filename
to Rubocop. This change was tested on a file I expected Rubocop to
ignore and the experience in vim was as I expected. However, I soon
found that ALE wasn't finding errors in files that should not be
ignored. After investigation, I found a few issues that this commit
fixes:
1. We were not properly passing the current filename. We now use
`expand` to get the filename.
2. The regular expression used in the callback was expecting the static
value of `_` for the filename in output. We now use a looser regular
expression that begins matching on the first `:`.
3. The linter was defined statically. By using the current filename when
defining the command the linter would always use the filename of the
first Ruby file the user opened. We now use a `command_callback` to
inject the proper filename.
I tested these changes on a configuration with included and excluded
files and found it to work as I expected. Apologies for the earlier
incorrect change.
When using `--stdin`, Rubocop requires that you also pass the associated
file name. ALE was previously passing `_` as the filename. By passing
the actual relative path to the file and enabling the
`--force-exclusion` option, we can get Rubocop to respect excluded files
in the configuration.
Closes#197
This PR first and formost implements support for dot-seperate filetypes,
a very trivial change.
This closes#132
But more importantly, this PR vastly improves the test quality for
`ale#linter#Get`. It enables us to reset the state of ale's internal
linter cache, to facilitate better testing, as well as making use of
mocked linters instead of depending on linters on disk (which may
change). In addition, a dummy linter is defined to test the autoloading
behavior.
Header guards were removed from all linters as:
* A: ale won't try and load linters if they already exist in memory
* B: we can't reset state for testing if they can't be loaded again
* First pass at optimizing ale to autoload
First off, the structure/function names should be revised a bit,
but I will wait for @w0rp's input before unifying the naming style.
Second off, the docs probably need some more work, I just did some
simple find-and-replace work.
With that said, this pull brings major performance gains for ale. On my
slowest system, fully loading ale and all its code takes around 150ms.
I have moved all of ale's autoload-able code to autoload/, and in
addition, implemented lazy-loading of linters. This brings load time on
that same system down to 5ms.
The only downside of lazy loading is that `g:ale_linters` cannot be
changed at runtime; however, it also speeds up performance at runtime by
simplfying the logic greatly.
Please let me know what you think!
Closes#59
