The typical usage pattern would be to run a test (or simply a compilation command) at given points in history. The shell command is ran (from the worktree root), and the rebase is stopped when the command fails, to give the user an opportunity to fix the problem before continuing with "git rebase --continue". This needs a little rework of skip_unnecessary_picks, which wasn't robust enough to deal with lines like exec >"file name with many spaces" in the todolist. The new version extracts command, sha1 and rest from each line, but outputs the line itself verbatim to avoid changing the whitespace layout.

# After setting the fake editor with this function, you can
|
|
#
|
|
# - override the commit message with $FAKE_COMMIT_MESSAGE
|
|
# - amend the commit message with $FAKE_COMMIT_AMEND
|
|
# - check that non-commit messages have a certain line count with $EXPECT_COUNT
|
|
# - check the commit count in the commit message header with $EXPECT_HEADER_COUNT
|
|
# - rewrite a rebase -i script as directed by $FAKE_LINES.
|
|
# $FAKE_LINES consists of a sequence of words separated by spaces.
|
|
# The following word combinations are possible:
|
|
#
|
|
# "<lineno>" -- add a "pick" line with the SHA1 taken from the
|
|
# specified line.
|
|
#
|
|
# "<cmd> <lineno>" -- add a line with the specified command
|
|
# ("squash", "fixup", "edit", or "reword") and the SHA1 taken
|
|
# from the specified line.
|
|
#
|
|
# "#" -- Add a comment line.
|
|
#
|
|
# ">" -- Add a blank line.
