const alreadyWarnedAbout = []
export function* fsaCompliance() {
yield* takeEvery('*', function* checkCompliance(action) {

jwarby / tag.vim
Created September 17, 2015 06:35
Append hashtags to the end of a commit message in Vim - intended for adding the initials of peer reviewers, but will work for any tags (you may want to change the function name if so). Usage: :PRed JB EC / :PRed JB / :PRed JB EC DS, etc
function! AddPeerReviewerInitials(...)
" Go to the top of the file
execute ':normal gg'
" Find the first comment line, and go up one line
let lineIndex = search('^#') - 1
" If line is blank, go up another one (my setup adds a new line when amending commit messages)
if !getline(lineIndex)
let lineIndex = lineIndex - 1
