Run: pullRequest,
|

Usage: `
|
|
pull-request [-focpd] [-b <BASE>] [-h <HEAD>] [-r <REVIEWERS> ] [-a <ASSIGNEES>] [-M <MILESTONE>] [-l <LABELS>]
|
|
pull-request -m <MESSAGE> [--edit]
|
|
pull-request -F <FILE> [--edit]
|
|
pull-request -i <ISSUE>
|
|
`,
|
|
Long: `Create a GitHub Pull Request.
|
|
|
|
## Options:
|
|
-f, --force
|
|
Skip the check for unpushed commits.
|
|
|
|
-m, --message <MESSAGE>
|
|
The text up to the first blank line in <MESSAGE> is treated as the pull
|
|
request title, and the rest is used as pull request description in Markdown
|
|
format.
|
|
|
|
If multiple <MESSAGE> options are given, their values are concatenated as
|
|
separate paragraphs.
|
|
|
|
--no-edit
|
|
Use the message from the first commit on the branch as pull request title
|
|
and description without opening a text editor.
|
|
|
|
-F, --file <FILE>
|
|
Read the pull request title and description from <FILE>.
|
|
|
|
-e, --edit
|
|
Further edit the contents of <FILE> in a text editor before submitting.
|
|
|
|
-i, --issue <ISSUE>
|
|
Convert <ISSUE> (referenced by its number) to a pull request.
|
|
|
|
You can only convert issues authored by you or that which you have admin
|
|
rights over. In most workflows it is not necessary to convert issues to
|
|
pull requests; you can simply reference the original issue in the body of
|
|
the new pull request.
|
|
|
|
-o, --browse
|
|
Open the new pull request in a web browser.
|
|
|
|
-c, --copy
|
|
Put the URL of the new pull request to clipboard instead of printing it.
|
|
|
|
-p, --push
|
|
Push the current branch to <HEAD> before creating the pull request.
|
|
|
|
-b, --base <BASE>
|
|
The base branch in the "[<OWNER>:]<BRANCH>" format. Defaults to the default
|
|
branch of the upstream repository (usually "master").
|
|
|
|
See the "CONVENTIONS" section of hub(1) for more information on how hub
|
|
selects the defaults in case of multiple git remotes.
|
|
|
|
-h, --head <HEAD>
|
|
The head branch in "[<OWNER>:]<BRANCH>" format. Defaults to the currently
|
|
checked out branch.
|
|
|
|
-r, --reviewer <USERS>
|
|
A comma-separated list of GitHub handles to request a review from.
|
|
|
|
-a, --assign <USERS>
|
|
A comma-separated list of GitHub handles to assign to this pull request.
|
|
|
|
-M, --milestone <NAME>
|
|
The milestone name to add to this pull request. Passing the milestone number
|
|
is deprecated.
|
|
|
|
-l, --labels <LABELS>
|
|
Add a comma-separated list of labels to this pull request. Labels will be
|
|
created if they do not already exist.
|
|
|
|
-d, --draft
|
|
Create the pull request as a draft.
|
|
|
|
## Examples:
|
|
$ hub pull-request
|
|
[ opens a text editor for writing title and message ]
|
|
[ creates a pull request for the current branch ]
|
|
|
|
$ hub pull-request --base OWNER:master --head MYUSER:my-branch
|
|
[ creates a pull request with explicit base and head branches ]
|
|
|
|
$ hub pull-request --browse -m "My title"
|
|
[ creates a pull request with the given title and opens it in a browser ]
|
|
|
|
$ hub pull-request -F - --edit < path/to/message-template.md
|
|
[ further edit the title and message received on standard input ]
|
|
|
|
## Configuration:
|
|
|
|
* 'HUB_RETRY_TIMEOUT':
|
|
The maximum time to keep retrying after HTTP 422 on '--push' (default: 9).
