From 7eae7812915602ece637714e6f82d4551e9697b6 Mon Sep 17 00:00:00 2001 From: Jon Parise Date: Fri, 28 Sep 2018 11:42:50 -0700 Subject: Add elixir-ls language server support 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. --- README.md | 2 +- ale_linters/elixir/elixir_ls.vim | 19 ++++++++++++++ doc/ale-elixir.txt | 13 ++++++++++ doc/ale.txt | 3 ++- .../test_elixir_ls_command_callbacks.vader | 29 ++++++++++++++++++++++ 5 files changed, 64 insertions(+), 2 deletions(-) create mode 100644 ale_linters/elixir/elixir_ls.vim create mode 100644 test/command_callback/test_elixir_ls_command_callbacks.vader diff --git a/README.md b/README.md index 80768f07..ec9092b9 100644 --- a/README.md +++ b/README.md @@ -117,7 +117,7 @@ formatting. | Dafny | [dafny](https://rise4fun.com/Dafny) !! | | Dart | [dartanalyzer](https://github.com/dart-lang/sdk/tree/master/pkg/analyzer_cli) !!, [language_server](https://github.com/natebosch/dart_language_server), [dartfmt](https://github.com/dart-lang/sdk/tree/master/utils/dartfmt) | | Dockerfile | [hadolint](https://github.com/hadolint/hadolint) | -| Elixir | [credo](https://github.com/rrrene/credo), [dialyxir](https://github.com/jeremyjh/dialyxir), [dogma](https://github.com/lpil/dogma), [mix](https://hexdocs.pm/mix/Mix.html) !!| +| Elixir | [credo](https://github.com/rrrene/credo), [dialyxir](https://github.com/jeremyjh/dialyxir), [dogma](https://github.com/lpil/dogma), [mix](https://hexdocs.pm/mix/Mix.html) !!, [elixir-ls](https://github.com/JakeBecker/elixir-ls) | | Elm | [elm-format](https://github.com/avh4/elm-format), [elm-make](https://github.com/elm-lang/elm-make) | | Erb | [erb](https://apidock.com/ruby/ERB), [erubi](https://github.com/jeremyevans/erubi), [erubis](https://github.com/kwatch/erubis) | | Erlang | [erlc](http://erlang.org/doc/man/erlc.html), [SyntaxErl](https://github.com/ten0s/syntaxerl) | diff --git a/ale_linters/elixir/elixir_ls.vim b/ale_linters/elixir/elixir_ls.vim new file mode 100644 index 00000000..d5ad7cfc --- /dev/null +++ b/ale_linters/elixir/elixir_ls.vim @@ -0,0 +1,19 @@ +" Author: Jon Parise +" Description: elixir-ls integration (https://github.com/JakeBecker/elixir-ls) + +call ale#Set('elixir_elixir_ls_release', 'elixir-ls') + +function! ale_linters#elixir#elixir_ls#GetExecutable(buffer) abort + let l:dir = ale#path#Simplify(ale#Var(a:buffer, 'elixir_elixir_ls_release')) + let l:cmd = ale#Has('win32') ?
