I've been using vim for years, but I've just started integrating eslint (through ALE). I've found that sometimes I want to be able to quickly add an /* eslint-ignore-next-line */
. For example:
...
❌ if (m = /^-l(\d+)$/.exec(args[i])) t.len = m[1];
...
~/some/dir/file.js [+]
cond-assign: Expected a conditional expression and instead saw an assignment.
It's really handy that ALE gives you the code at the bottom of the window, but being lazy I want to automate adding the comment/hint:
/* eslint-ignore-next-line cond-assign */
Is there a way to access that information at the bottom of the screen in a vim script/function?
Though not documented, ALE stores lint information in the b:ale_highlight_items
variable.
David784's solution didn't work for me because I had customized the location-list text using ALE's g:ale_echo_msg_format
configuration option. So I modified it to obtain the information directly from b:ale_highlight_items
instead of parsing it out of the location-list.
Here it is:
command! ALEIgnoreEslint call AleIgnoreEslint()
function! AleIgnoreEslint()
" https://stackoverflow.com/questions/54961318/vim-ale-shortcut-to-add-eslint-ignore-hint
let l:codes = []
if (!exists('b:ale_highlight_items'))
echo 'cannot ignore eslint rule without b:ale_highlight_items'
return
endif
for l:item in b:ale_highlight_items
if (l:item['lnum']==line('.') && l:item['linter_name']=='eslint')
let l:code = l:item['code']
call add(l:codes, l:code)
endif
endfor
if len(l:codes)
exec 'normal O/* eslint-disable-next-line ' . join(l:codes, ', ') . ' */'
endif
endfunction
