Vim script to show git commit diff in vertical split while writing commit messages
" Put this in your .vimrc and whenever you `git commit` you'll see the diff of your commit next to your commit message.
" For the most accurate diffs, use `git config --global commit.verbose true`
" BufRead seems more appropriate here but for some reason the final `wincmd p` doesn't work if we do that.
autocmd VimEnter COMMIT_EDITMSG call OpenCommitMessageDiff()
function OpenCommitMessageDiff()
" Save the contents of the z register
let old_z = getreg("z")
let old_z_type = getregtype("z")

Screencapture and animated gifs

Screencapture and animated gifs

I say "animated gif" but in reality I think it's irresponsible to be serving "real" GIF files to people now. You should be serving gfy's, gifv's, webm, mp4s, whatever. They're a fraction of the filesize making it easier for you to deliver high fidelity, full color animation very quickly, especially on bad mobile connections. (But I suppose if you're just doing this for small audiences (like bug reporting), then LICEcap is a good solution).

Capturing (Easy)

  1. Launch quicktime player
  2. do Screen recording
