Show HN: make git ignore certain changed files in repo

These are the aliases I have set in my .gitconfig for a similar (same?) purpose:

  [alias]
  ignore = !git update-index --assume-unchanged
  unignore = !git update-index --no-assume-unchanged
  ignored = !git ls-files -v | grep "^[[:lower:]]"

Usage: `git ignore foo.rb`, `git unignore foo.rb`; `git ignored` to list all currently ignored files.

Awesome, that'll do as well, thanks

For those who aren't familiar with the git subcommand, `git update-index --[no-]assume-unchanged` is at the core of this script.

It's useful for ignoring checked-in files locally, such as overriding app config settings for a local dev server.

How is this better than creating a local branch ?

This has nothing to do with branching. Here is the idea I tried to replicate http://tortoisesvn.net/docs/release/TortoiseSVN_en/tsvn-dug-...

I'm a little confused by what this does... Can't you just not 'git add' a file to have git ignore its changes?

The file still shows up in status and, the most important, changes from file still shows up in 'add|checkout|reset -p' which I use all the time.

gitignore only works on files that haven't been added. This looks like it's for files already being tracked.

I'm going to try this next week; this is something we could use at work.

Plus, can't beat the license.

I'd be happy to hear your testimonials!

I use it at work everyday, it comes in very handy when you need to keep some changes only specific to your local setup (monkey patching, javascript page speed measurements, weird php local config stuff, etc, etc).

Nice! I remember being surprised that .gitignore didn't do this.

Right, gitignore can only help with untracked files, not tracked and changed.

Back in the day when I was using SVN, its ignore-on-commit feature (GUI only, but anyway) was incredibly useful.
