From 61248e1453dc6373160154e1f6855ffc510a7dfc Mon Sep 17 00:00:00 2001 From: Pat Brisbin Date: Sat, 22 Apr 2023 09:05:50 -0400 Subject: Add fourmolu fixer (#4501) * Add fourmolu fixer Fourmolu is aversion of Ormolu that supports configuration. This fixer was modeled after the Ormolu one, but using the "stack executable" approach of the Brittany and Stylish Haskell fixers. * Sort supported-tools.md --- autoload/ale/fix/registry.vim | 5 +++++ autoload/ale/fixers/fourmolu.vim | 20 ++++++++++++++++++ doc/ale-haskell.txt | 20 ++++++++++++++++++ doc/ale-supported-languages-and-tools.txt | 1 + doc/ale.txt | 1 + supported-tools.md | 1 + test/fixers/test_fourmolu_fixer_callback.vader | 29 ++++++++++++++++++++++++++ 7 files changed, 77 insertions(+) create mode 100644 autoload/ale/fixers/fourmolu.vim create mode 100644 test/fixers/test_fourmolu_fixer_callback.vader diff --git a/autoload/ale/fix/registry.vim b/autoload/ale/fix/registry.vim index f7fff6a7..66cdc707 100644 --- a/autoload/ale/fix/registry.vim +++ b/autoload/ale/fix/registry.vim @@ -561,6 +561,11 @@ let s:default_registry = { \ 'suggested_filetypes': ['haskell'], \ 'description': 'A formatter for Haskell source code.', \ }, +\ 'fourmolu': { +\ 'function': 'ale#fixers#fourmolu#Fix', +\ 'suggested_filetypes': ['haskell'], +\ 'description': 'A formatter for Haskell source code.', +\ }, \ 'jsonnetfmt': { \ 'function': 'ale#fixers#jsonnetfmt#Fix', \ 'suggested_filetypes': ['jsonnet'], diff --git a/autoload/ale/fixers/fourmolu.vim b/autoload/ale/fixers/fourmolu.vim new file mode 100644 index 00000000..399ec0f4 --- /dev/null +++ b/autoload/ale/fixers/fourmolu.vim @@ -0,0 +1,20 @@ +call ale#Set('haskell_fourmolu_executable', 'fourmolu') +call ale#Set('haskell_fourmolu_options', '') + +function! ale#fixers#fourmolu#GetExecutable(buffer) abort + let l:executable = ale#Var(a:buffer, 'haskell_fourmolu_executable') + + return ale#handlers#haskell_stack#EscapeExecutable(l:executable, 'fourmolu') +endfunction + +function! ale#fixers#fourmolu#Fix(buffer) abort + let l:executable = ale#fixers#fourmolu#GetExecutable(a:buffer) + let l:options = ale#Var(a:buffer, 'haskell_fourmolu_options') + + return { + \ 'command': l:executable + \ .
