Good Shit

Shit I have found useful, recorded for future reference. Focused on tools and workflows I like to use. Feel free to open a PR if you have a good trick, too!

Get rid of incorrect HTML-escaping on Pro Git

Fire up the console and copy-paste. > is but one of many, but it's the most common one I've run into.

$('pre').each(function(idx, pre) {
  $(pre).text($(pre).text().replace(/&lt;/g, '<'))
  $(pre).text($(pre).text().replace(/&gt;/g, '>'))
  $(pre).text($(pre).text().replace(/&amp;/g, '&'))
})

Change a variable name project-wide

In project root dir: $ vim $(ack 'bad_variable_name' -l)
In vim: :argdo %s/bad_variable_name/good_variable_name/gc | update

Step 1: open every file containing bad_variable_name in vim.

Step 2: argdo applies the command to every file given as an argument; c flag can be left off, but then make sure to git add -p; piping to update saves each file after making all substitutions. If you don't do the ack bit at first, add an e flag to the :%s to suppress any errors from files without a match.
