Atom Linter plugin for ElixirC

linter-elixirc

This linter plugin for Linter provides an interface to elixirc/mix. It will be used with files that have the "source.elixir" syntax (ie. *.ex; *.exs).

There are limitations with ElixirC that:

• in case of compilation error, it will only show first error
• it does not work with buffers, so linting on fly is disabled

Installation

Plugin requires Linter package and it should install it by itself. If it did not, please follow Linter instructions here.

Method 1: In console

$ apm install linter-elixirc

Method 2: In Atom

1. Edit > Preferences (Ctrl+,)
2. Install > Search "linter-elixirc" > Install

Settings

Plugin should work with default settings. If not:

1. Edit > Preferences (Ctrl+,)
2. Packages > Search "linter-elixirc" > Settings
3. Elixirc path - use which elixirc to find path. ie. /usr/local/bin/elixirc
4. Mix path - use which mix to find path. ie. /usr/local/bin/mix
5. Always use elixirc - leave it disabled, unless mix compile is too slow.

Usage

If you open folder with mix project (mix.exs exists in project's root folder), linter will use mix compile to include all dependencies, unless you enable "Always use elixirc" setting.

If you open single file, linter will use elixirc. This will try to find dependencies in a place where mix projects do (_build/dev/lib/*/ebin). If dependency path is different, then every external dependency will trigger CompileError.

Since *.ex files are not compiled by mix compile, they are always linted using elixirc.
