Module editor 

$EDITOR / $VISUAL spawn helper for mkit commit.

Behaviour:

• Honour $GIT_EDITOR first, then $EDITOR, then $VISUAL.
• Fall back to vi on Unix / notepad on Windows when no env var is set, so mkit commit works out-of-the-box.
• Write template to a tempfile, spawn the editor, wait, read the file back, strip any line whose first non-whitespace byte is #, and return the trimmed message.

Constants

COMMIT_EDITMSG_TEMPLATE

Template rendered into the tempfile before spawning the editor.

MAX_COMMIT_MSG_BYTES

Maximum commit-message file size read back from the editor (1 MiB).

Functions

spawn_editor

Spawn the user’s editor on a tempfile pre-populated with template, then read the file back, strip #-comment lines, and return the trimmed result.

strip_comments_and_trim

Strip all lines whose first non-whitespace byte is #, then trim trailing whitespace.
