Summary: Many of the template keywords in our extensions were being registered incorrectly, causing their help output to be rendered incorrectly in the "hg help templates" output. The ones in smartlog.py were particularly bad, as most of them showed only their description, without displaying the name of the template. In smartlog.py only singlepublicsuccessor was being displayed correctly, because it's docstring explicitly included it's own name at the start. This fixes all of our extensions to consistently use the registrar.templatekeyword() decorator to register the keywords. This decorator automatically prefixes the help message with the keyword name. The mercurial/extensions.py code will explicitly check to see if an extension contains an "templatekeyword" attribute, and if so it will register any keywords contained in this registry after calling extsetup(). Test Plan: Added new unit tests to check the output of "hg help templates" for the affected keywords.

myparent.py - Commit template keywords based on your previous commit
|
|
|
|
If your diff stacks are comprised of related diffs, many commits will share the
|
|
same reviewers, tasks and even the title prefix. With this extension, mercurial
|
|
can prefill the relevant fields based on your previous commit in the stack.
|
|
|
|
The extension adds five new keywords:
|
|
|
|
- *myparentdiff* the diff number of the parent commit
|
|
- *myparentreviewers* the reviewers of the parent commit
|
|
- *myparentsubscribers* the subscribers of the parent commit
|
|
- *myparenttasks* the tasks of the parent commit
|
|
- *myparenttitleprefix* the prefix as defined by [] of the parent commit.
|
|
E.g. '[e2e automation] foo bar' -> '[e2e automation]'
|
|
|
|
After enabling the extension, change the default commit template:
|
|
|
|
[committemplate]
|
|
emptymsg={myparenttitleprefix}
|
|
Summary: {myparentdiff}
|
|
Test Plan:
|
|
Reviewers: {myparentreviewers}
|
|
Subscribers: {myparentsubscribers}
|
|
Tasks: {myparenttasks}
|
|
Blame Revision:
|
|
|
|
In some (all?) repositories at Facebook the commit template is overridden at
|
|
the repository level. If that is the case, add the line above to the `.hg/hgrc`
|
|
file inside the repository (e.g. ~/www/.hg/hgrc).
