We have such a test already (squash_fixups_above_first_commit.go), but it can't
be used for what we want to check here, because it uses the first commit, and we
can't move down from there. So create a new one that basically does the same
thing, but for a commit in the middle. The focus of this new test is to check
how the selection behaves; as you can see, there is a problem both when creating
a fixup and when squashing fixups. We'll address these separately in the next
commits.
It starts a rebase on the bottom-most commit of the range, and sets all the
selected commits to "edit" (skipping merge commits, because they can't be
edited).
The additional branch head icon is more confusing than useful in this situation.
The update-ref entries show very clearly where the branch heads will go when
continuing the rebase; the information where the branch heads used to be before
the rebase is not really needed here, and just makes the display more confusing.
I'm not adding more tests here because the changes to the existing tests
demonstrate the change clearly enough.
To do that, change the "Apply fixup commits" command to show a menu with the two
choices "in current branch" and "above the selected commit"; we make "in current
branch" the default, as it's the more useful one most of the time, even though
it is a breaking change for those who are used to "shift-S enter" meaning
"squash above selected".
This adds a bunch of tooltips to keybindings and updates some keybinding descriptions (i.e. labels).
It's in preparation for displaying more keybindings on-screen (in the bottom right of the screen),
and so due in part to laziness it shortens some descriptions so that we don't need to manage both
a short and long description (for on-screen vs in-menu). Nonetheless I've added a ShortDescription
field for when we do want to have both a short and long description.
You'll notice that some keybindings I deemed unworthy of the options view have longer descriptions,
because I could get away with it.
This is useful if you want to move a range of commits, so you select them, and
then realize it's better to do it in an interactive rebase. Pressing 'i'
preserves the range now.
A common issue I have is that I want to move a commit from the top of my branch
all the way down to the first commit on the branch. To do that, I need to navigate
down to the first commit on my branch, press 'e' to start an interactive rebase,
then navigate back up to the top of the branch, then move my commit back down to
the base. This is annoying.
Similarly annoying is moving the commit one-by-one without explicitly starting
an interactive rebase, because then each individual step is its own rebase which
takes a while in aggregate.
This PR allows you to press 'i' from the commits view to start an interactive
rebase from an 'appropriate' base. By appropriate, we mean that we want to start
from the HEAD and stop when we reach the first merge commit or commit on the main
branch. This may end up including more commits than you need, but it doesn't make
a difference.
This fixes two minor problems with the prompts:
1. When pressing shift-A in the local commits view, it would first prompt
whether to stage all files, and then it would prompt whether to amend the
commit at all. This doesn't make sense, it needs to be the other way round.
2. When pressing shift-A on the head commit in an interactive rebase, we would
ask whether they want to amend the last commit, like when pressing shift-A in
the files view. While this is technically correct, the fact that we're
amending the head commit in this case is just an implementation detail, and
from the user's point of view it's better to use the same prompt as we do for
any other commit.
To fix these, we remove the confirmation panel from AmendHelper.AmendHead() and
instead add it at the two call sites, so that we have more control over this.
When editing a commit, the index of the current commit can change; for example,
when merge commits are involved, or when working with stacked branches where
"update-ref" commands may be added above the selected commit.
Reselect the current commit after pressing "e"; this requires doing the refresh
blocking on the main thread. (Another option that I considered was to use a
SYNC refresh, and then select the new line with an OnUIThread inside the Then
function. This also works, but results in a very visible lag.)
We want to mark all local branch heads with a "*" in the local commits panel, to
make it easier to see how branches are stacked onto each other. In order to not
confuse users with "*" markers that they don't understand, do this only for the
case where users actually use stacked branches; those users are likely not going
to be confused by the display. This means we want to filter out a few branch
heads that shouldn't get the marker: the current branch, any main branch, and
any old branch that has been merged to master already.
This test not only tests the correct handling and display of the updateRef
command, but also the visualization of branch heads in the commits panel. Since
we are about to change the behavior here, extend the test so that a master
commit is added (we don't want this to be visualized as a branch head), and then
a stack of two non-main branches. At the end of this branch we only want to
visualize the head commit of the first.
This test is almost identical to swap_in_rebase_with_conflict.go, except that it
sets the commit that will conflict to "edit".
This test is interesting because there's special code needed to determine
whether an "edit" command conflicted or not, i.e. whether to show the "confl"
entry. In this case we do. We have lots of other tests already that have "edit"
commands that don't conflict, so that's covered already.
When stopping in a rebase because of a conflict, it is nice to see the commit
that git is trying to apply. Create a fake todo entry labelled "conflict" for
this, and show the "<-- YOU ARE HERE ---" string for that one (in red) instead
of for the real current head.
This test is interesting because it already behaves as desired: since git has
rescheduled the "pick" command, we do _not_ want to show a "conflict" entry in
this case, as we would see the same commit twice then.
We have not been good at consistent casing so far. Now we use 'Sentence case' everywhere. EVERYWHERE.
Also Removing 'Lc' prefix from i18n field names: the 'Lc' stood for lowercase but now that everything
is in 'Sentence case' there's no need for the distinction.
I've got a couple lower case things I've kept: namely, things that show up in parentheses.
By constructing an arg vector manually, we no longer need to quote arguments
Mandate that args must be passed when building a command
Now you need to provide an args array when building a command.
There are a handful of places where we need to deal with a string,
such as with user-defined custom commands, and for those we now require
that at the callsite they use str.ToArgv to do that. I don't want
to provide a method out of the box for it because I want to discourage its
use.
For some reason we were invoking a command through a shell when amending a
commit, and I don't believe we needed to do that as there was nothing user-
supplied about the command. So I've switched to using a regular command out-
side the shell there
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.
This fixes two problems with the "amend commit with staged changes" command:
1. Amending to a fixup commit didn't work (this would create a commmit with the
title "fixup! fixup! original title" and keep that at the top of the branch)
2. Unrelated fixup commits would be squashed too.
The added integration test verifies that both of these problems are fixed.
It used to work on the assumption that rebasing commits in lazygit's model
correspond one-to-one to lines in the git-rebase-todo file, which isn't
necessarily true (e.g. when users use "git rebase --edit-todo" at the custom
command prompt and add a "break" between lines).
