hg equivalent of git add -p?

Question

Is there a mercurial equivalent of git add -p?

Quoting from man, git-add with the option -p (or --patch) does the following:

Interactively choose hunks of patch between the index and the work tree and add them to the index. This gives the user a chance to review the difference before adding modified contents to the index.

Answer 1

Have a look at the record extension (which comes bundled with Mercurial).

Note that since Mercurial doesn't have the concept of the staging area like git, running hg record will simply allow you to examine, hunk by hunk, the modifications in your working copy. Any changes you choose to record will be committed, and any changes you choose not to record are simply left as modifications in your working copy.

Answer 2

The Record Extension is the standard tool for this. It allows you to pick hunks to include or not in a commit. Once you've enabled the extension in your hgrc, the command is just

hg record 

The CRecord Extension gives you a TUI (Text User Interface) on top of this which allows you to go down to which lines you want to include. This isn't standard though, so it need downloading to a directory before you can enable it in your hgrc.

hg crecord

Edit:

1. The Record extension is no longer necessary since approx v3.4. Now various commands support the -i or --interactive flag. For example:

   hg commit -i 

   ...will ask you hunk by hunk what you want to include.

2. CRecord made it in to 3.8 as a core feature. Add the following to your .hgrc

   [ui] interface = curses 

   Now, --interactive commands will bring up the same interface as the old CRecord extension.
