Usage

Installation

Install ripgrep. You need version 0.8 or later.
Install deadgrep from MELPA (do M-x package-install RET deadgrep within Emacs 25.1 or later), or copy it into your ~/.emacs.d.
(Optional) add deadgrep to a convenient shortcut. I like F5.

(global-set-key (kbd "<f5>") #'deadgrep)

Keybindings

Navigating results:

Key	Action
`RET`	Visit the result, file or push button at point
`o`	Visit the result in another window
`n` and `p`	Move between results or buttons
`N` and `P`	Move between search hits
`M-n` and `M-p`	Move between file headers

Starting/stopping a search:

Key	Action
`S`	Change the search term
`I`	Switch to incremental search, re-running on every keystroke
`D`	Change the search directory
`^`	Re-run the search in the parent directory
`g`	Re-run the search
`TAB`	Expand/collapse results for a file
`C-c` `C-k`	Stop a running search
`C-u`	A prefix argument prevents search commands from starting automatically.

Additional interactive commands

Name	Action
`imenu`	Move between files in a results buffer.
`deadgrep-kill-all-buffers`	Kill all open deadgrep buffers.
`deadgrep-debug`	In a results buffer, view the `rg` command, output and environment used.

Minibuffer

You use the minibuffer to enter a new search term.

You can also reuse a previous search term with M-p in the minibuffer. To edit the default search term, use M-n.

Easy Debugging

The easiest way to debug search results is to review the actual rg command executed.

Fortunately, the deadgrep-debug function makes it easy:

Move to the deadgrep results buffer.
Type M-x deadgrep-debug.
Strike enter, and the debug buffer will appear.
Move to the deadgrep debug buffer.

Study the results to review the rg command string and other debugging information to assist you.

Features

Super Fast

Deadgrep uses ripgrep for extremely fast text searches.

If you change your search settings, deadgrep will immediately re-run your search.

Context Aware

Deadgrep works hard to minimise your keystrokes.

Search term: If the region is active, deadgrep uses that.

Search directory: If your current file is in a VCS repository, deadgrep uses that for your search directory.

Regexp and case sensitivity options: Deadgrep re-uses whatever settings you used in your last search.

Globbing and file types: Deadgrep suggests file types and globbing options that match the file you started the search from.

Host: If you're editing a remote file with Tramp, deadgrep will search the remote machine. This requires rg to be installed on that machine.

Easy Filtering

Didn't get the results you wanted? It's easy to change the search term, search type, or search directory, directly from the results buffer. Just push the relevant button.

Polish

Deadgrep uses spinners to give you feedback on whether your search has finished.

It highlights regexp syntax according to the syntax accepted by rg.

When navigating to a line that matched, the relevant part of the line is temporarily highlighted.

You can collapse and expand files with TAB.

Deadgrep handles minified files robustly.

You can always jump to exactly the position that point is on, even when searching files that contain tab characters. You can also navigate to the file itself from the file headings.

Beta Features

You can now edit files directly from results buffers with M-x deadgrep-edit-mode.

It is currently in beta, so you may also want to try this pull request on wgrep.

Alternative Projects

I believe that deadgrep is the best tool for doing Emacs text searches, but there are some other great tools out there. See ALTERNATIVES for a discussion.
