Gsub

A CLI program to do find and replace!

Installation

You can grab a binary release from the releases tab. Install it somewhere on your PATH.

Here's a one-liner:

$ curl -L https://github.com/rzane/gsub/releases/download/0.1.1/gsub-0.1.1_darwin_x86_64.tar.gz | tar xvf - -C /usr/local

Currently, binary releases are only available for Darwin. If you're on Linux, you'll have to build from source.

Usage

# Find occurances of `foo` in the current directory
$ gsub foo

# Find lines ending with `foo` in the current directory
$ gsub 'foo$'

# Find an replace all occurances of `foo` with `bar`
$ gsub foo --replace bar --commit

# Find an replace with backtracking
$ gsub 'foo (\w+) bar' --replace 'Got: \1' --commit

# Preview a find/replace (just omit the --commit)
$ gsub 'foo' --replace bar

# Find occurances of `foo` in the `app` and `lib` directories
$ gsub foo app lib

# Specify paths
$ gsub foo 'spec/**/*_spec.rb' 'app/**/*.rb'

# Exclude files from paths
$ gsub foo 'spec/**/*_spec.rb' --exclude 'spec/foo_spec.rb' --exclude 'spec/bar_*_spec.rb'

Development

To compile Gsub, you'll need Crystal. Instructions for your operating system can be found here: http://crystal-lang.org/docs/installation.
