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

Last active October 6, 2016 00:27
A middleware for Redux which verifies that all actions dispatched to the store follow the Flux Standard Action (https://github.com/acdlite/flux-standard-action) pattern. A warning is shown (only once) for each action which violates the pattern.

return ({ dispatch, getState }) => next => action => {
const { type } = action
if (!isFSA(action) && alreadyWarnedAbout.indexOf(type) === -1) {
