New properties for closest tag message

[nxn-4-wdf]

Describe the idea (required)

Properties commit.message.full and commit.message.short are useful to get information about the last commit.
But it is often quite technical.

If you want a more general, semantic description, it is in the messages from annotated tags, for example, created with git tag -a <tagname> -m "Message for tag <tagname>..." .

I would suggest to get the closest tag annotation and put it into new properties, for example, with names closest.tag.message.full and closest.tag.message.short.

Tell us about the expected behaviour (required)

You can get these messages with command git tag and option -n.

More specifically, when the user requests:

• closest.tag.message.full: get the output of git tag -n99 <tagname> (full message, maximum 99 lines)
• closest.tag.message.short: get the output of git tag -n1 <tagname> (only 1 line)

If the closest tag is not annotated, the git commands automatically get the message from the last git commit instead, therefore, this would be equivalent to git.commit.message.*.

Context (optional)

A tag usually represents a new release or a new version of the code.

Well used, an annotated tag message provides a practical way to convey a high-level summary over the content of this release.
