Description

The Radicle patch command is used for managing changesets inside of Radicle repositories.

Though many actions can be performed using rad patch, certain patch-related actions use git directly. For example, opening a patch is typically done using git push, while merging a patch is done with a combination of git merge and git push.

To make this possible, Radicle ships with a helper program, git-remote-rad which is invoked by git on push and fetch to and from Radicle remotes.

Commands

With no arguments, rad patch defaults to the list command, showing the list of open patches for the current repository.

show

Shows information on the given patch.

<patch-id>

The patch to show

--patch, -p

Show the patch changes in git patch format

--verbose, -v

Show additional information about the patch

edit

Edits a patch revision comment. To edit the patch title or description, pass in the <patch-id>. To edit a revision comment, pass that revision’s <revision-id>.

<revision-id>

The revision to edit.

--message, -m [<string>]

Comment message to the patch or revision. If omitted, Radicle will prompt for a comment string via $EDITOR.

list

List patches in the current repository. The default is --open.

--all

List all patches, including merged and archived patches

--archived

List only archived patches

--merged

List only merged patches

--open

List only open patches

--draft

List only draft patches

ready

Mark a patch as ready to review. This changes the state of a patch from draft to open.

--undo

Change a patch back to draft

set

Set the current branch upstream to a patch reference. This configures your branch such that pushing will update the specified patch.

<patch-id>

The patch to set this branch’s upstream to

update

Updates a patch to the current repository HEAD. This is a low-level command that should only be used when using git push rad is not possible.

--message, -m [<string>]

Provide a comment message to the revision

--no-message

Leave the revision comment message blank

comment

Comment on a patch revision, optionally replying to an existing comment.

<revision-id>

The patch revision to comment on. Since all Patch IDs are also Revision IDs, a Patch ID is also accepted.

--message, -m <string>

Comment message. If omitted, Radicle will prompt for a comment string via $EDITOR. Multiple messages will be concatinated with a blank line in between.

--reply-to <comment-id>

Optional comment to reply to. If ommitted, the comment is a top-level comment on the given revision.

Opening a patch

To open a patch, we start by making changes to our working copy, typically on a feature branch. For example:

$ git checkout -b fix/option-parsing
  ... edit some files ...
$ git commit -a -m "Fix option parsing"

Once our changes are ready to be proposed as a patch, we push them via git to a special reference on the rad remote, that is used for opening patches (refs/patches):

$ git push rad HEAD:refs/patches
✓ Patch 90c77f2c33b7e472e058de4a586156f8a7fec7d6 opened
...

Radicle will then open your editor, where you can edit the patch title and description. Make sure either EDITOR or VISUAL is set in your environment (See environ(7) for more details). Once you’re done, simply save and exit your editor. If successful, the patch is opened and its identifier is printed out. You can then display the patch metadata using the show sub-command:

$ rad patch show 90c77f2

Note that you don’t have to use the full patch identifier. An unambiguous prefix of it also works.

Radicle can create a patch from any Git commit. Simply substitute HEAD with the branch name or commit hash you wish to propose a patch for. For example:

$ git push rad d39fe32387496876fae6446daf3762aacf69d83b:refs/patches

After the patch is opened, you may notice that Radicle has set your branch upstream to something like rad/patches/90c77f2c33b7e472e058de4a586156f8a7fec7d6. This means your branch is now associated with the newly opened patch, and any push from this branch will result in the patch being updated. See the next section on updating a patch for more information.

Options

When opening a patch, various options can be specified using git push options. This is done via the -o or --push-option flag. For example, -o=patch.draft. The full list of options follows:

sync, no-sync

Whether or not to sync with the network after the patch is opened. Defaults to sync.

patch.draft

Open the patch as a draft. Turned off by default.

patch.message=<message>

To prevent the editor from opening, you can specify the patch message via this option. Multiple patch.message options are concatenated with a blank line in between.

patch.base=<oid>

The base commit onto which this patch should be merged. By default, this is your "master" branch. When building stacked patches, it may be useful to set this to the head of a previous patch.

For more information on push options, see git-push(1).

Updating a patch

To update a patch, we simply make our changes locally and push:

$ git commit --amend
$ git push --force
✓ Patch 90c77f2 updated to d0018fcc21d87c91a1ff9155aed6b4e57535566b
...

Note that this will only work if the current branch upstream is set correctly. This happens automatically when a patch is opened from a branch without an upstream set. In the above example, we used the --force option, since the commit was amended. This is common practice when a patch has been reworked after receiving a review.

If the branch upstream is not set to the patch reference, ie. rad/patches/<id>, you can do so using rad patch set <id>.

As with opening a patch, you will be asked to enter a reason for updating the patch, via your editor. Simply save and exit when you’re done; or leave it blank to skip this step.

It’s also possible to change the patch base during an update. Simply use the patch.base push option as described in Opening a patch.

Checking out a patch

When working with patches opened by peers, it’s often useful to be able to checkout the code in its own branch. With a patch checkout, you can browse the code, run tests and even propose your own update to the patch. The checkout sub-command is used to that effect:

$ rad patch checkout 90c77f2

Radicle will create a new branch if necessary and checkout the patch head. From there, you can git-push to publish a patch update, or simply browse the code.

Merging a patch

Once a patch is ready to merge, the repository maintainer simply has to use the git-merge(1) command from the "master" branch and push via git. For example, if some patch 26e3e56 is ready to merge, the steps would be:

$ rad patch checkout 26e3e56
✓ Switched to branch patch/26e3e56
$ git checkout master
$ git merge patch/26e3e56
$ git push rad
✓ Patch 26e3e563ddc7df8dd0c9f81274c0b3cb1b764568 merged
To rad://z42hL2jL4XNk6K8oHQaSWfMgCL7ji/z6MknSLrJoTcukLrE435hVNQT4JUhbvWLX4kUzqkEStBU8Vi
   f2de534..d6399c7  master -> master

In the above, we created a checkout for the patch, and merged that branch into our master branch. Then we pushed to our rad remote.

Listing patches

To list patches, run rad patch. By default, this will only show open patches. To list all patches, including ones that have been merged or archived, add the --all option.
