D8 - hooks

src: Pluralsight, Timothy Ghanim

• types of hooks:
  • pre-: called before the git command executes; can abort the git command
  • post-: called after the git command executes; doesn't affect the git command
  • misc: called while the git command executes; can abort the git command

• in the above example, a commit workflow is demonstrated

• note that the first three hooks (pre and two misc hooks) abort the workflow if they fail, but the final one (post) does not

• hooks can be written in any language - git just needs an executable to run

• command line argument, input, output and error streams, and environment variables are used to receive results from the hook

• it checks for the exit code to determine success or failure

• hooks are neutral to the IDE

• they run in the same repo
