Using exclusion patterns when grepping05 Mar 2018
I like Git. A lot. After years of use it has
really grown on me. It's (mostly) fast, (often) reliable, and (always)
distributed. For me, all properties are important, but being able to
git init to start a new project in seconds is the best feature.
When it comes to working with Git day-to-day, a nice GUI can really make a difference. In Emacs world, of course it's Magit. Outside of Emacs (brr), git-cola looks to be the most promising one. If you're aware of something better, please share - I'm keeping a list of suggestions for my non-Emacs using colleagues.
Ivy integration for Git
The main two commands in ivy that I use for Git are:
counsel-git: select a file tracked by Git
counsel-rg: grep for a line in all files tracked by Git, using ripgrep as the backend.
There are many alternatives to
counsel-rg that use a different
counsel-rg is the fastest, especially when I have
to deal with Git repositories that are 2Gb in size (short explanation:
it's a Perforce repo with a bunch of binaries, because why not; and
I'm using git-p4 to interact with
.ignore with ripgrep
.ignore file to the root of your project can really speed
up your searches. In my sample project, I went from 10k files to less
than 500 files.
/TAGS *.min.js* /Build/Output/ /ThirdParty/
As you can see, both file patterns and directories are supported. One
other nifty thing that I discovered only recently is that you can use
ripgrep as the backed for
counsel-git in addition to
counsel-rg. Which means the same
.ignore file is used for both
commands. Here's the setting:
(setq counsel-git-cmd "rg --files")
And here's my setting for
(setq counsel-rg-base-command "rg -i -M 120 --no-heading --line-number --color never %s .")
The main difference in comparison to the default
-M 120 which means: truncate all lines
that are longer than 120 characters. This is really helpful when Emacs
is accepting input from
ripgrep: a megabyte long line of minified JS
is not only useless since you can't see it whole, but it will also
likely hang Emacs for a while.
I hope you found these bits of info useful. Happy hacking!
