From b7996803c99a0a5f5dba1cef330a2bfb77f08c42 Mon Sep 17 00:00:00 2001 From: Chris Marchesi Date: Fri, 27 Apr 2018 15:40:02 -0700 Subject: [PATCH] Add ALEJobStarted User autocommand event The ALELintPre and ALELintPost autocommand events are currently being used by lightline-ale to refresh the status line and check the linter status for a current buffer. One of the plugin's checks looks to see if linters are currently running, via ale#engine#IsCheckingBuffer(). This currently only works partially in certain situations. In my particular case, working with Go files, this only seems to function properly when a file is initially opened. Saving a file does not correctly update the status. This seems to be due to the fact that ALELintPre actually runs before any jobs are carried out, making it plausible that hooking into ALELintPre for the purpose of checking to see if there are any currently running linters for a buffer is unreliable as it would be prone to pretty obvious race conditions. This adds a new User autocommand, ALEJobStarted, that gets fired at the start of every new job that is successfully run. This allows a better point to hook into checking the linter status of a buffer using ale#engine#IsCheckingBuffer() by ensuring that at least one job has started by the time IsCheckingBuffer is run. --- autoload/ale/engine.vim | 2 ++ doc/ale.txt | 7 +++++++ 2 files changed, 9 insertions(+) diff --git a/autoload/ale/engine.vim b/autoload/ale/engine.vim index 0704fd5b..e1c41552 100644 --- a/autoload/ale/engine.vim +++ b/autoload/ale/engine.vim @@ -586,6 +586,8 @@ function! s:RunJob(options) abort \ 'output': [], \ 'next_chain_index': l:next_chain_index, \} + + silent doautocmd User ALEJobStarted endif if g:ale_history_enabled diff --git a/doc/ale.txt b/doc/ale.txt index de6507e3..d52e8fe9 100644 --- a/doc/ale.txt +++ b/doc/ale.txt @@ -2452,7 +2452,14 @@ ALEFixPost *ALEFixPost-autocmd* autocmd User ALELintPre let s:ale_running = 1 | redrawstatus autocmd User ALELintPost let s:ale_running = 0 | redrawstatus augroup end + < +ALEJobStarted *ALEJobStarted-autocmd* + + This |User| autocommand is triggered immediately after a job is successfully + run.
