Sometimes we populate the commit message panel with a pre-created commit
message. The two cases where this happens is:
- you type `w` to commit, in which case we put the skipHookPrefix in the subject
- you have a commitPrefix pattern, in which case we match it against the branch
name and populate the subject with the replacement string if it matches
In either case, if you have a preserved commit message, we use that.
Now, when you use either of these and then cancel, we preserve that initial,
unchanged message and reuse it the next time you commit. This has two problems:
it strips spaces, which is a problem for the commitPrefix patterns, which often
end with a space. And also, when you change your config to experiment with
commitPrefix patterns, the change seemingly doesn't take effect, which can be
very confusing.
To fix both of these problems, only preserve the commit message when it is not
identical to the initial message.
This is how we do it for confirmation with suggestions too, so be consistent. It
will make things easier later in this branch if we only have one context per
"panel" on the stack, even if the panel consists of two views.
Concretely this means:
- only push the message context onto the stack when opening the panel (this
requires making the description view visible manually; we do the same for
suggestions)
- when switching between message and description, use ReplaceContext rather than
PushContext
Previously we would hide it if no onSwitchToEditor function was set; that was
from a time when <c-o> was bound directly to the switch-to-editor command. Now
it is bound to showing a menu, and that menu is always available even if no
onSwitchToEditor function is set. (We rather need to disable the switch to
editor item _within_ that menu, see next commit.)
Only do this when an onSwitchToEditor function is actually provided. For the
"Move patch into new commit" command we don't, because it isn't totally
straightforward in that case.
This is useful for when you begin to type the message in lazygit's commit panel,
and then realize that you'd rather use your editor's more powerful editing
capabilities. Pressing <c-o> will take you right there.
Previously we used a single-line prompt for a tag annotation. Now we're using the commit message
prompt.
I've had to update other uses of that prompt to allow the summary and description labels to
be passed in
When we use the one panel for the entire commit message, its tricky to have a keybinding both for adding a newline and submitting.
By having two panels: one for the summary line and one for the description, we allow for 'enter' to submit the message when done from the summary panel,
and 'enter' to add a newline when done from the description panel. Alt-enter, for those who can use that key combo, also works for submitting the message
from the description panel. For those who can't use that key combo, and don't want to remap the keybinding, they can hit tab to go back to the summary panel
and then 'enter' to submit the message.
We have some awkwardness in that both contexts (i.e. panels) need to appear and disappear in tandem and we don't have a great way of handling that concept,
so we just push both contexts one after the other, and likewise remove both contexts when we escape.
