I don't see a reason why this restriction to have the selection be always
visible was necessary. Removing it has two benefits:
1. Scrolling a list view doesn't change the selection. A common scenario: you
look at one of the commits of your current branch; you want to see the how
many'th commit this is, but the beginning of the branch is scrolled off the
bottom of the commits panel. You scroll down to find the beginning of your
branch, but this changes the selection and shows a different commit now - not
what you want.
2. It is possible to scroll a panel that is not the current one without changing
the focus to it. That's how windows in other GUIs usually behave.
We now refresh the staging panel when doing an unscoped refresh, so that if we commit from the staging panel we escape
back to the files panel if need be. But that causes flickering when doing an unscoped refresh from other contexts,
because the refreshStagingPanel function assumes that the staging panel has focus. So we're adding a guard at the top
of that function to early exit if we don't have focus.
When cycling history, we want to make it so that upon returning to the original prompt, you get your text back.
Importantly, we don't want to use the existing preservedMessage field for that because that's only for preserving
a NEW commit message, and we don't want the history stuff of the commit reword flow to overwrite that.
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 begins a big refactor of moving more code out of the Gui struct into contexts, controllers, and helpers. We also move some code into structs in the
gui package purely for the sake of better encapsulation

This broke with 40f6767cfc77; the symptom is that starting lazygit with a git
arg (e.g. "lazygit log") wouldn't activate the requested panel correctly. While
it would show in the expanded view, it didn't have a green frame, and keyboard
events would go to the files panel.
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.
We already show "merge" todo entries when starting an interactive rebase with
--rebase-merges outside of lazygit. Changing the type of a merge entry to "pick"
or "edit" doesn't make sense and shouldn't be allowed. Earlier in this branch we
have started to show "update-ref" entries, these can't be changed either (they
can be moved, though).
You might argue that it should be possible to change them to "drop", but in the
case of "update-ref" this doesn't make sense either, because "drop" needs a Sha
and we don't have one here. Also, you would then be able to later change it back
to "pick", so we would have to remember that this isn't allowed for this
particular drop entry; that's messy, so just disallow all editing.
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).
This is useful when working with stacked branches, because you can now move
"pick" entries across an update-ref command and you can tell exactly which
branch the commit will end up in.
It's also useful to spot situations where the --update-refs option didn't work
as desired. For example, if you duplicate a branch and want to rebase only one
of the branches but not the other (maybe for testing); if you have
rebase.updateRefs=true in your git config, then rebasing one branch will move
the other branch along. To solve this we'll have to introduce a way to delete
the update-ref entry (maybe by hitting backspace?); this is out of scope for
this PR, so for now users will have to type "git rebase --edit-todo" into the
custom command prompt to sort this out.
We will also have to prevent users from trying to turn update-ref commands into
other commands like "pick" or "drop"; we'll do this later in this branch.
The main reason for doing this (besides the reasons given for Status in the
previous commit) is that it allows us to easily convert from TodoCommand to
Action and back. This will be needed later in the branch. Fortunately,
TodoCommand is one-based, so this allows us to add an ActionNone constant with
the value 0.
This is unrelated to the changes in this PR, but since we are doing the same
thing for the commit.Action field in the next commit, it makes sense to do it
for Status too for consistency. Modelling this as an enum feels more natural
than modelling it as a string, since there's a finite set of possible values.
And it saves a little bit of memory (not very much, since none of the strings
were heap-allocated, but still).
We print this to the terminal after lazygit quits rather than showing it in a
panel at startup, so as to not annoy people too much. Hopefully it will still be
prominent enough this way.
The "open" command is supposed to behave in the same way as double-clicking a
file in the Finder/Explorer. The concept of jumping to a specific line in the
file doesn't make sense for this; use "edit" instead.
Previously we would have tried to do the rebase, resulting in a long and
somewhat cryptic error message from git; now we check ourselves and show a less
intimidating message.
We refresh the view after reading just enough to fill it, so that we see the
initial content as quickly as possible, but then we continue reading enough
lines so that we can tell how long the scrollbar needs to be, and then we
refresh again. This can result in slight flicker of the scrollbar when it is
first drawn with a bigger size and then jumps to a smaller size; however, that's
a good tradeoff for a solution that provides both good speed and accuracy.
All callers in this file now use reverseOnGenerate=false and
keepOriginalHeader=true, so hard-code that in the call to ModifiedPatchForLines
and get rid of the parameters.
There's no reason to have two different ways of applying patches for whole-file
patches and partial patches; use --reverse for both. Not only does this simplify
the code a bit, but it fixes an actual problem: when reverseOnGenerate and
keepOriginalHeader are both true, the generated patch header is broken (the two
blobs in the line `index 6d1959b..6dc5f84 100644` are swapped). Git fails to do
a proper three-way merge in that case, as it expects the first of the two blobs
to be the common ancestor.
It would be possible to fix this by extending ModifiedPatchForLines to swap the
two blobs in this case; but this would prevent us from concatenating all patches
and apply them in one go, which we are going to do later in the branch.
We are going to add one more flag in the next commit.
Note that we are not using the struct inside patch_manager.go; we keep passing
the individual flags there. The reason for this will become more obvious later
in this branch.
This is the working tree state at the time the model commits were loaded. This
avoids a visual glitch with the "You Are Here" label appearing at times when it
is not supposed to.
Instead, derive it from context at display time (if we're rebasing, it's the
first non-todo commit). This fixes the problem that unfolding the current
commit's files in the local commits panel would show junk in the frame's title.
Along the way we make sure to only display the "<--- YOU ARE HERE" string in the
local commits panel; previously it would show for the top commit of a branch or
tag if mid-rebase.
It's not so much the total number of commits that matters here, it's just
whether we are on the first one. (This includes the other condition.)
This allows us to get rid of the condition in rebase.go.
Instead of rebasing from the commit below the current one and then setting the
current one to "edit", we rebase from the current one and insert a "break" after
it. In most cases the behavior is exactly the same as before, except that the
new method also works if the current commit is a merge commit. This is useful if
you want to create a new commit at the very beginning of your branch (by editing
the last commit before your branch).
There are two reasons for doing this:
1. The view cursor position is often out of sync with the selected line; see
first commit of this branch.
2. The highlighting is already turned off when the view loses focus, and never
turned back on thereafter. So just turn it off from the start then.
We already have this very convenient behavior of jumping to the next stageable
line after staging something. However, while this worked well for staging
single lines or hunks, it didn't work correctly when staging a range of lines;
in this case we want to start searching from the first line of the range.
While we try to keep the view's cursor position in sync with the context state's
selectedLineIdx (at least when pressing up or down), there are enough situations
where the two run out of sync; for example when initially opening the view, or
after staging a hunk, or when scrolling the view using the wheel. While it would
be possible to fix these situations to keep them always in sync, it doesn't seem
worth it, because the view's cursor position isn't really used for anything
else. So we rather special-case the SelectedLine/SelectedLineIdx functions of
ViewDriver to query the context state's selectedLineIdx directly if it is a
patch explorer context.
There's no need for refreshing anything; all that's needed is to re-focus the
selected list item. This way it will also work in other panels, which we are
about to add in the next commit.
