* Add credo --strict option
If a user sets 'let g:ale_elixir_credo_strict=1' it will run credo with
--strict instead of suggest. The default (0) is to run as suggest.
* Added credo docs
Previously, elixir-ls would treat each sub-project within an umbrella as
standalone, which isn't desirable from a language server perspective.
Added ale#handlers#elixir#FindMixUmbrellaRoot, which locates the current
project's root and then continues searching upwards for a potential
umbrella project root. This literally looks just two levels up to keep
things simple while keeping in line with Elixir project conventions.
Use this new function to determine elixir-ls's LSP project root.
This adds generic configuration dictionary support to the elixir-ls
linter. This is useful for disabling its built-in Dialyzer support, for
example, which can improve startup time.
The configuration dictionary is a little verbose. I considered reducing
the user configuration to only the nested settings dictionary (and
having the linter implementation wrap it in the top-level `elixirLS`
dictionary), but leaving it fully configurable simplifies the code and
removes any assumptions about current or future ElixirLS behavior.
ElixirLS (https://github.com/JakeBecker/elixir-ls) is an LSP server for
Elixir. It's distributed as a release package that can be downloaded
from https://github.com/JakeBecker/elixir-ls/releases or built locally.
The easiest way to start it is via Unix- and Win32-specific helper
scripts, so that's the basis of this command integration. Alternatively,
we could implement the contents of those platform-specific scripts in
the linter's command callback in a language-neutral way, but there isn't
any benefit to doing that aside from eliminating the platform check, and
that could prove to be too tight of a coupling going forward.
* FIX: use mix from the project root directory
* Move find root project function to autoloaded handlers
* add tests for #ale#handlers#elixr#FindMixProjectRoot
* The project style linter now runs while you type.
* Now the scripts for checking the project require blank lines.
* Many style issues have been found and fixed.
When dializer isn't a dependency, mix dialyzer recompiles the whole
project because it's not possible to know if this command dialyzer exist
or not until recompilation is done. Then the timestamps of the project
is messed up which results in broken hot-loading. In this case, mix help
dialyzer would return zero which prevents compilation of the whole
project since dialyzer isn't installed, it's help manual doesn't exist.
When dialyzer is a dependency, mix dialyzer would just run the command.
In this case, mix help dialyzer would return 1 which allows mix dialyzer
to run.
* Add Elixir linter for dialyxir
* Update doc/ale.txt with dialyxir
* Keep elixir tools alphabetically ordered in README
* Add a missing entry for dialyxir to the main documentation file.
* 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 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
By default, Credo attributes input from STDIN as though it came from a
file named `stdin`. This change passes the buffer's filename, too, so
that Credo can use that information when applying its configuration.
This is a nice improvement because files like `mix.exs` are normally
excluded from Credo-based linting. Previously, ALE would show lint
warnings for those files as they were edited. Now, they are correctly
honor the Credo configuration and don't produce lint output.
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
* Add Credo linter for Elixir
* Add requested changes
TODO: check if all message types are covered in `if` chain.
* Add information about Credo linter to README
* Add information about Credo linter to doc
