# Helper functions used by interactive rebase tests. # 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: # # "" -- add a "pick" line with the SHA1 taken from the # specified line. # # " " -- add a line with the specified command # ("squash", "fixup", "edit", or "reword") and the SHA1 taken # from the specified line. # # "exec_cmd_with_args" -- add an "exec cmd with args" line. # # "#" -- Add a comment line. # # ">" -- Add a blank line. set_fake_editor () { write_script fake-editor.sh <<-\EOF case "$1" in */COMMIT_EDITMSG) test -z "$EXPECT_HEADER_COUNT" || test "$EXPECT_HEADER_COUNT" = "$(sed -n '1s/^# This is a combination of \(.*\) commits\./\1/p' < "$1")" || exit test -z "$FAKE_COMMIT_MESSAGE" || echo "$FAKE_COMMIT_MESSAGE" > "$1" test -z "$FAKE_COMMIT_AMEND" || echo "$FAKE_COMMIT_AMEND" >> "$1" exit ;; esac test -z "$EXPECT_COUNT" || test "$EXPECT_COUNT" = $(sed -e '/^#/d' -e '/^$/d' < "$1" | wc -l) || exit test -z "$FAKE_LINES" && exit grep -v '^#' < "$1" > "$1".tmp rm -f "$1" echo 'rebase -i script before editing:' cat "$1".tmp action=pick for line in $FAKE_LINES; do case $line in squash|fixup|edit|reword) action="$line";; exec*) echo "$line" | sed 's/_/ /g' >> "$1";; "#") echo '# comment' >> "$1";; ">") echo >> "$1";; *) sed -n "${line}s/^pick/$action/p" < "$1".tmp >> "$1" action=pick;; esac done echo 'rebase -i script after editing:' cat "$1" EOF test_set_editor "$(pwd)/fake-editor.sh" } # After set_cat_todo_editor, rebase -i will write the todo list (ignoring # blank lines and comments) to stdout, and exit failure (so you should run # it with test_must_fail).
