# git-footers(1) Manual Page

## NAME

git-footers - Extract meta-information expressed as footers in a commit message.

## SYNOPSIS

    git footers [--key FOOTER] REF
    git footers [--position | --position-ref | --position-num] REF

## DESCRIPTION

`git footers` extracts information included in commit messages as "footers", which are roughly like HTTP headers except they are at the end. For example, a commit might look like:

    This is a fancy commit message.

    Cr-Commit-Position: refs/heads/main@{#292272}
    Tech-Debt-Introduced: 17 nanoMSOffices

`git footers` knows how to extract this information.

Footers are order-independent and can appear more than once. Thus they are treated as a multimap.

## OPTIONS

If no options are given, all footers are printed, with their names case-normalized.

--key FOOTER

  Extract all the headers associated with the given key, and print one per line. If there are no footers with this key, produces no output and exits successfully.

--position

  Extract the Chrome commit position from the footers. This first attempts to get the value of the `Cr-Commit-Position` footer. If that doesn’t exist then it tries a heuristic based on `Git-Svn-Id`. Output is in one of the following forms:

      refs/heads/main@{#292272}
      refs/branch-heads/branchname

--position-num

  Extracts and prints the Chrome commit position number only (292272 in the example above). Exits with an error if one cannot be found.

--position-ref

  Extracts and prints the Chrome commit position ref name only (`ref/heads/main` or `refs/branch-heads/branchname` in the example above).

## EXAMPLE

    $ git footers HEAD
    Tech-Debt-Introduced: -4 microMSOffices
    Tech-Debt-Introduced: 17 microMSOffices
    Cr-Commit-Position: refs/heads/main@{#292272}

    $ git footers --key Tech-Debt-Introduced HEAD
    -4 microMSOffices
    17 microMSOffices

    $ git footers --position HEAD
    refs/heads/main@{#292272}

    $ git footers --position-num HEAD
    292272

    $ git footers --position-ref HEAD
    refs/heads/main
