Feature Request: View transformation operator for git commit object's read

[Jacek Lipiec]

Hey,

Recently I was thinking about various methods to bring order to a
chaos of commit messages that are used throughout the dev space –
namely conventional commits and, as alternative, emoji-log. First
method focuses on context, while the second one focuses on
presentation. Both are trying to bend current GIT capabilities to
convey context.

Feature request:
Option to add a transforming script to the output of all read
operations on commit object.

Example:
   $ GIT SHOW FDCCAE00C2D112717306F91A21BFA2BBDDB7DCF6
   COMMIT FDCCAE00C2D112717306F91A21BFA2BBDDB7DCF6
   MERGE: 6A235DB 0FCD13B

       FEAT(LANG): SOME LANG FEATURE

with view transformation script of, either:
   /^FEAT\((?<SCOPE>.+?)\)/ => 👌
   /^FEAT\((?<SCOPE>.+?)\)/ => <SPAN TITLE=”SCOPE: $SCOPE”>👌</SPAN>

it could work like this:
   $ GIT CONFIG VIEW.TRANSFORMATION.EMOJI=/^FEAT\((?<SCOPE>.+?)\):/ => 👌
   $ GIT CONFIG VIEW.TRANSFORMATION.FULLTEXT=/^FEAT\((?<SCOPE>.+?)\):/
=> FEATURE $REST WITH SCOPE $SCOPE
   $ GIT CONFIG
VIEW.TRANSFORMATION.SHELLSCRIPT=/HOME/JACEK/PARSE-COMMIT-MESSAGE.SH
   $ GIT SHOW –TRANSFORM=EMOJI FDCCAE00C2D112717306F91A21BFA2BBDDB7DCF6
   COMMIT FDCCAE00C2D112717306F91A21BFA2BBDDB7DCF6
   MERGE: 6A235DB 0FCD13B

      👌: SOME LANG FEATURE

   $ GIT SHOW –TRANSFORM= FULLTEXT FDCCAE00C2D112717306F91A21BFA2BBDDB7DCF6
   COMMIT FDCCAE00C2D112717306F91A21BFA2BBDDB7DCF6
   MERGE: 6A235DB 0FCD13B
   AUTHOR: JACEK LIPIEC <JACEK.LIPIEC.BC@GMAIL.COM>
   DATE:   THU NOV 7 21:11:45 2020 +0100

    FEATURE SOME LANG FEATURE WITH SCOPE LANG

Would allow both backwards compatibility and an option to return a
result in a way that can be easily read by humans, or alternatively,
easily parsable by machine.
