| # 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. |
