1 | # Helper functions used by interactive rebase tests. | |
2 | ||
3 | # After setting the fake editor with this function, you can | |
4 | # | |
5 | # - override the commit message with $FAKE_COMMIT_MESSAGE | |
6 | # - amend the commit message with $FAKE_COMMIT_AMEND | |
7 | # - check that non-commit messages have a certain line count with $EXPECT_COUNT | |
8 | # - check the commit count in the commit message header with $EXPECT_HEADER_COUNT | |
9 | # - rewrite a rebase -i script as directed by $FAKE_LINES. | |
10 | # $FAKE_LINES consists of a sequence of words separated by spaces. | |
11 | # The following word combinations are possible: | |
12 | # | |
13 | # "<lineno>" -- add a "pick" line with the SHA1 taken from the | |
14 | # specified line. | |
15 | # | |
16 | # "<cmd> <lineno>" -- add a line with the specified command | |
17 | # ("pick", "squash", "fixup", "edit", "reword" or "drop") and the | |
18 | # SHA1 taken from the specified line. | |
19 | # | |
20 | # "exec_cmd_with_args" -- add an "exec cmd with args" line. | |
21 | # | |
22 | # "#" -- Add a comment line. | |
23 | # | |
24 | # ">" -- Add a blank line. | |
