This extension is distributed with Mercurial 2.3 and later.
Author: Augie Fackler
Works with: Mercurial 1.3 and beyond (tests are run against versions seen in the Makefile.)
In core since version 2.3
History editing plugin for Mercurial, heavily inspired by git rebase --interactive.
It allows selecting (pick), combining (fold), rejecting (drop) or modifying (edit) already commited changesets.
In versions of Mercurial after 2.3, enable the extension by adding the following lines to your configuration file:
[extensions] histedit =
For older versions, you need to grab the extension source and then configure your configuration file to enable the extension by adding following lines:
[extensions] histedit = ~/path/to/histedit/hg_histedit.py
3. Usage Scenario
The extension adds the histedit command, which takes a revision argument. All changesets from that revision and onwards are selected for history reordering and modification. They are presented as an ordered list with a changeset revision preceded by an action keyword for each line (action revision-id).
If you were to run hg histedit c561b4e977df for a repo with the history graph

an editor would open containing the following text:
pick c561b4e977df Add beta pick 030b686bedc4 Add gamma pick 7c2fd3b9020c Add delta # Edit history between c561b4e977df and 7c2fd3b9020c # # Commands: # p, pick = use commit # e, edit = use commit, but stop for amending # f, fold = use commit, but fold into previous commit # d, drop = remove commit from history # 0 files updated, 0 files merged, 0 files removed, 0 files unresolved
History rewriting works by reordering changesets so that they reflect a new ordering in the history graph, or by changing the desired action to take on each changeset. The possible actions are one of pick, fold, edit and drop:
- Simply accepts the changeset as is. This is the default action.
- Combines a changeset with the previous changeset in the list and opens an editor to edit the commit message.
Drops to the command prompt, allowing to edit files freely to commit some changes as a separate commit. When done, any remaining uncommitted changes will be committed as well. When done, run hg histedit --continue to finish this step or hg histedit --abort to abandon the new changes and keep the previous state.
- Removes the changeset from history.
When changes lead to conflicts then the user is dropped to the command prompt and has the very same options as when the edit action is selected. To accept new changes the hg histedit --continue command is used and to drop them the hg histedit --abort one.
