FOREWORDS

I don't mean the snippet at the bottom of this gist to be a generic plug-n-play solution to your search needs. It is very likely to not work for you or even break things, and it certainly is not as extensively tested and genericised as your regular third-party plugin.

My goal, here and in most of my posts, is to show how Vim's features can be leveraged to build your own high-level, low-maintenance, workflows without systematically jumping on the plugins bandwagon or twisting Vim's arm.

# Ensure all files staged for commit pass standard code style
function xargs-r() {
  # Portable version of "xargs -r". The -r flag is a GNU extension that
  # prevents xargs from running if there are no input files

Tags

Setup

Tell Vim to look for tags files:

• in the directory of the current file,
• in the working directory,
• and in every parent directory, recursively,

What to do with macros?

"Macro", you say? Or is that "recording"?

What people refer to as a "macro" is often actually a "recording".

You press qa to start recording your commands into register a, you do your thing, you stop your recording with q, and you play that recording back with @a.

Yes, what you just recorded is a macro, but macros are not necessarily recorded or even stored in registers.
