Search and refactoring tool based on ripgrep.

What is color-rg?

color-rg is a search and refactoring tool based on ripgrep.

I'm a big fan of color-moccur.el, this extension's name is a tribute to color-moccur.el!

Installation

Clone or download this repository (path of the folder is the <path-to-color-rg> used below).

In your ~/.emacs, add the following two lines:

(add-to-list 'load-path "<path-to-color-rg>") ; add color-rg to your load-path
(require 'color-rg)

If you use Mac, you also need to install exec-path-from-shell

Work with isearch

Add this into your emacs config file:

(define-key isearch-mode-map (kbd "M-s M-s") 'isearch-toggle-color-rg)

When using isearch-forward, type M-s M-s to search current isearch string with color-rg.

Research with new files

color-rg-rerun-change-files can limit search files with GLOB. This function used rg arguments '--type', '--add-type'.

Default search files is "everything" which means use rg without '--type' argument.

If search files is "all", search rg like "rg --type all".

Other complete candidates are mostly read from "rg --type-list" command, which is predefined in rg.

Of course you can specify your own GLOB, just insert them as you like. For example, if you input a GLOB like *mypersonalglob*, which match none of the candidates, then, color-rg will call shell command like:

rg --add-type 'custom:*mypersonalglob*' --type custom ...

Research with customized arguments

If none of the preset meet your requirements, color-rg-customized-search can release the full power of rg.

When color-rg-customized-search is called, the full command of rg will show up, and you can add any argument to rg as in shell.

you must escape special characters when using color-rg-customized-search, for example:

rg --type-add custom\:\*.el
# or
rg --type-add 'custom:*.el'
# or
rg --type-add "custom:*.el"
