"Parens and Performance" – counterpost

Kyle Simpson (@getify) wrote a very thoughtful post decrying optimize-js, which is a tool I wrote that exploits known optimizations in JavaScript engines to make JS bundles parse faster (especially minified bundles, due to what could be reasonably described as a bug in Uglify).

Kyle lays out a good case, but I tend to disagree with nearly all his points. So here's my rebuttal.

20:04 < ahdinosaur> if anyone is interested in a choo-like API where it's pull-streams all the way down, i made some helpers for `inu`: https://github.com/ahdinosaur/inux
20:04 < yoshuawuyts> ahdinosaur: I'm curious: how big is inu?
20:04 < yoshuawuyts> probably smaller than choo I'd think
20:05 < yoshuawuyts> well, inux would be more fair to compare I reckon but still
20:05 < ahdinosaur> one sec, i'll discify
20:05 < yoshuawuyts> ahdinosaur: I'm using this for choo https://github.com/yoshuawuyts/choo/blob/master/scripts/instrument#L24-L35
20:06 < yoshuawuyts> gzip size tends to translate slightly better I find
20:06 < ronnross> So curious how one would use something like https://codemirror.net/ in Choo.
20:07 < ronnross> Would you work directly with the dome of use subscriptions to handle working with it.
20:07 < ronnross> Might sound like a crazy question, but when I implemented it in Elm I had to use ports and subscriptions.

# In order for gpg to find gpg-agent, gpg-agent must be running, and there must be an env
# variable pointing GPG to the gpg-agent socket. This little script, which must be sourced
# in your shell's init script (ie, .bash_profile, .zshrc, whatever), will either start
# gpg-agent or set up the GPG_AGENT_INFO variable if it's already running.

# Add the following to your shell init to set up gpg-agent automatically for every shell
if [ -f ~/.gnupg/.gpg-agent-info ] && [ -n "$(pgrep gpg-agent)" ]; then
    source ~/.gnupg/.gpg-agent-info
    export GPG_AGENT_INFO
