Currently we try to delete a branch normally, and if git returns an error and
its output contains the text "branch -D", then we prompt the user to force
delete, and try again using -D. Besides just being ugly, this has the
disadvantage that git's logic to decide whether a branch is merged is not very
good; it only considers a branch merged if it is either reachable from the
current head, or from its own upstream. In many cases I want to delete a branch
that has been merged to master, but I don't have master checked out, so the
current branch is really irrelevant, and it should rather (or in addition) check
whether the branch is reachable from one of the main branches. The problem is
that git doesn't know what those are.
But lazygit does, so make the check on our side, prompt the user if necessary,
and always use -D. This is both cleaner, and works better.

This might seem controversial; in many cases the client code gets longer,
because it needs an extra line for an explicit `return nil`. I still prefer
this, because it makes it clearer which calls can return errors.
I can only guess, but I think this was a typo (or a copy-paste-o) when this code
was written. It was introduced in 55af07a1bb, and I think the defer was kept by
accident; if it had been on purpose, then the statement would have been put
right after the Lock call.
This solves several problems that arise from opening a menu while the prompt is
open. We might try to solve these in a different way, e.g. by dismissing the
search prompt before opening a menu, but restricting what you can do while the
prompt is open seems like the more robust fix.
To achieve this, we
- call resetKeyBindings both when opening and when closing the search/filter
prompt
- change the keybindings to only contain the ones for the search prompt when
that context is active.
So far, lazygit has always auto-staged files as soon as the conflict markers
disappeared from them, which means that we could rely on any file that still had
a status of "UU" to still contain conflict markers.
We are going to make the auto-staging optional in the next commit, and in that
case the user will want to manually stage "UU" files; so we must now check
whether the file contains conflict markers, and disallow the staging in that
case.
We make the name of the GetSelectedRefRangeForDiffFiles very specific on purpose
to make it clear that this is only for switching to diff files, so the
implementations can make assumptions about that (unlike GetSelectedRef, which is
used for different purposes and needs to stay more generic).
Right now it doesn't do very much yet, but it's still worth it even in this
state, I'd say. The function is going to become a bit longer in the next commit,
though.
In other views that show lists of commits (reflog and stash) it doesn't make
sense to show a range diff of selected entries because they don't form a linear
sequence, so we keep the previous behavior of showing the diff for the free end
of the selection range in those view.
The same applies to the commits view if the selection range includes rebasing
todos; these can have an arbitrary order, and a range diff doesn't make sense
for those.
Hopefully this will help alleviate the problem that diffing mode is sticky, and
you often forget that it's still on.
Make it magenta like the mode text in the information view.
This fixes two problems:
- Set the title ref to the commit description (like
SwitchToDiffFilesController.enter does), rather than just the hash
- SetTitleRef only sets the title of the DynamicTitleBuilder, but doesn't set it
on the view; this only happens in ContextMgr.Activate, so you'd have to switch
to a different side panel and then back to see the new title.
The three nested `if` statements may looks strange, and you might wonder why we
don't have single one with &&. The answer is that later in this branch we will
add an `else` block to the middle one.
In the next commit it will be reused for checking whether we need to reset the
patch; and extracting it makes it easier to extend it for non-sticky diff ranges
later in the branch.
viewFiles is only called from enter; it doesn't make much sense to fill in a
SwitchToCommitFilesContextOpts struct to pass it to viewFiles for this one call.
Simply inline viewFiles into enter and get rid of all that.
I found this indirection confusing when reading the code. It looks like
SwitchToDiffFilesController is instantiated with different such contexts, but
it's always Contexts.CommitFiles, so just use that directly.
Note that this doesn't only affect the diff views, which are the ones where we
want this, but also the status view, where the plan was to keep them underlined
always for better discoverability. We could make this configurable dynamically
(by adding another flag to ViewUpdateOpts), but actually I think it's fine this
way.
We fixed one specific scenario where this happened ealier in this branch, but in
case there are more that we don't know about yet, at least make sure we don't
crash.
I don't know what this condition is supposed to guard against, or whether we
really need it (it was added in 06ca71e955, and the commit message of that
commit only says "fix bug"). But if we do need it, then it seems that `>=` is
more correct than `>`.
It is already possible to search a filtered list by searching first, and then
enabling a filter, so I found it inconsistent to not allow searching when you
are already filtering. One reason for not allowing this might be that the search
status (on the left) hides the filter status (on the right), but if we think
that's enough reason to not allow both at the same time, then we should cancel a
search when we enter filtering.
There are many situations where this can arise. Some examples are:
- the terminal window is small, and you are showing a view that shows more
content than fits into the view port, and the view is scrolled all the way
down; now you resize the terminal window to a taller size. Previously, the
scroll position of the view would stay the same, so it would add blank space
at the bottom; now it will scroll to fill that blank space with content
- expandFocusedSidePanel is on, you go to the bottom of a list view, now switch
to a different panel, then scroll that (now unfocused) panel all the way down
with the scroll wheel; now you focus that panel again. It becomes larger
because of the accordion behavior, but would show blank space at the bottom.
And probably others that I can't remember right now. I only remember that I
always found it confusing to look at a view that had blank space at the bottom
even though it had more content to scroll into view.
It might seem cleaner to integrate this into the text style system, so that you
could say `ts := ts.Url("some link")` and then `ts.Sprint("my text")`. However,
this would require adding a new field to TextStyle, which I didn't want to do.
It is just unexpected and confusing when it isn't.
There's something weird about the cursor position when scrolling it out of view;
it will be shown clamped to the visible area of the view (as if it had moved in
the opposite direction than the scroll direction), but then when you type
something again, or just move the cursor with the arrow keys, the view will jump
back to where the cursor really was. This looks confusing, and it might be
reason enough not to allow scrolling the view at all.
It doesn't seem to be used by anything, it looks like we only need to implement
the method so that the IController interface is satisfied. But still, it doesn't
hurt to be correct here, and might avoid confusion in the future when somebody
does try to use the method.
Since onNewRepo calls resetKeybindings, which reinitializes the keybindings for
custom commands, all we have to do for this is store a pointer to a config
instead of storing the customCommands, so we get the up-to-date ones every time.
It still doesn't update the view immediately when reloading the config, only the
next time the status panel is focused. But at least it does it then; writing the
code to update the panel when reloading the config is probably not justifiable.
This allows having per-repo config files with different languages per repo. Now
granted, this is not an important use case that we need to support; however, the
goal is to eventually make all configs hot-reloadable (as opposed to loading
them only once at startup), so this is one step in that direction.
For now we only support .git/lazygit.yml; in the future we would also like to
support ./.lazygit.yml, but that one will need a trust prompt as it could be
versioned, which adds quite a bit of complexity, so we leave that for later.
We do, however, support config files in parent directories (all the way up to
the root directory). This makes it possible to add a config file that applies to
multiple repos at once. Useful if you want to set different options for all your
work repos vs. all your open-source repos, for instance.
Split it so createAllViews instanciates the views, and sets those properties
that are independent of the user config, and configureViewProperties which sets
those things that do depend on the user config. For now we call the second right
after the first, but later we'll call configureViewProperties after reloading
the user config.
It was added in 043cb2ea44, and the commit message was "reload config whenever
returning to gui". I don't understand what this means; Run() is called exactly
once after startup, so it would just reload the config again for no reason.
We will add a real way of reloading the config whenever it has changed later in
this branch.
When clicking in a single-file diff view to enter staging (or custom patch
editing, when coming from the commit files panel), you needed to press escape
twice to exit, where the first press would seemingly do nothing.
The reason for this was that after clicking in the diff we end up in non-sticky
range select mode, but only with a single line selected, which is basically
indistinguishable from line select mode.
SelectedCommit is context-dependent and points to SelectedLocalCommit,
SelectedReflogCommit, or SelectedSubCommit depending on which panel is active.
If none of these panels is active, it returns the selected local commit, which
is probably the most useful default (e.g. when defining custom commands for the
Files panel).
The comments that I'm deleting here explain why we need the bool; however, in
our case that's a theoretical issue. It would only arise if we ever were to pass
a nil context to SetParentContext, which we never do.
Also, use the user's shell (from the SHELL env variable) instead of bash. Both
of these together allow users to use their shell aliases or shell functions in
the interactive command prompt.
This change reduces the number of calls during application startup to
one, calling GetRepoPaths() earlier than previously and plumbing the
repoPaths struct around to achieve this end.
The current behaviour when creating a new branch off of a remote branch
is to always track the branch it was created from.
For example, if a branch 'my_branch' is created off of the remote branch
'fix_crash_13', then 'my_branch' will be tracking the remote
'fix_crash_13' branch.
It is common practice to have both the local and remote branches named
the same when the local is tracking the remote one. Therefore, it is
reasonable to expect that 'my_branch' should not track the remote
'fix_crash_13' branch.
The new behaviour when creating a new branch off of a remote branch is
to track the branch it was created from only if the branch names match.
If the branch names DO NOT match then the newly created branch will not
track the remote branch it was created from.
For example, if a user creates a new branch 'fix_crash_13' off of the
remote branch 'fix_crash_13', then the local 'fix_crash_13' branch will
track the remote 'fix_crash_13' branch.
However, if the user creates a new branch called 'other_branch_name' off
of the remote branch 'fix_crash_13', then the local 'other_branch_name'
branch will NOT track the remote 'fix_crash_13' branch.
The default shortcut to open git difftool (ctrl+t) is not available on
the "Local Branches" window. It is available when selecting a commit
from a local branch, a remote branch, or a tag from the "Local Branches"
window.
This is inconsistent since branches or tags are also commits, the
shortcut should also work on them directly.
This commit remedies this inconsistency by allowing the use of the
shortcut directly on a branch or a tag. The shortcut works both in the
"standard" mode and the "diffing" mode.
This reverts commit 3af545daf7, reversing
changes made to 629b7ba1b8.
We changed our mind about this and want to provide different options for
achieving the same thing, but with more flexibility.
The highlight is normally turned off in HandleFocusLost, but that's not called
when using ReplaceContext (and changing this would be a lot of work, it seems),
so turn it off manually here for now.
Probably not the most import feature in the world, but when resizing the
terminal window while multiple popup panels were open at the same time, we would
only resize the topmost one.
The main reason for changing this is because it makes the next commit easier to
implement.
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
We forgot to handle the "suggestions" and "commitDescription" view names.
Instead of listing all the names of views that can appear in popups though,
let's use the context kind for this, which feels more robust.
This is a change in behavior: previously, clicking outside of the search or
filter prompt would close the prompt, now it no longer does (because search has
a persistent popup kind, but it wasn't listed in the list of view names before).
An inactive selection is one where the view is part of the context stack, but
not the active view. For example, the files view when you enter the staging
panel, or any view when you open a panel.
Remove the old mechanism of clearing the highlight in Layout.
This fixes a problem with a wrong highlight showing up in the staging panel when
entering a file with only staged changes.
Reproduction recipe:
1. stage all changes in a file by pressing space on it in the files panel
2. enter the staged changes panel by pressing enter
3. unstage one of the changes
This makes the unstaged changes panel visible, but keeps the focus in the staged
changes panel. However, the highlight in the unstaged changes view becomes
visible, as if it were focused.
To explain why this happens, you need to know how the selection highlighting of
a view is turned on or off. It is turned on when it gains the focus, i.e. when
ActivateFocus is called on it, which in turn happens when PushContext is called.
It is turned off in Layout when gocui sees that the current view is no longer
the same as last time, in which case it calls onViewFocusLost on the previous
current view.
This mechanism only works reliably when there is at most one PushContext call
per event handler. If there is more than one, then the first one gets its
highlight turned on, then the second one, but since gocui has never seen the
first one as the active view in Layout, it doesn't get the highlight turned off
again even though it should.
And this happens in the above scenario. When pressing enter on a file with only
staged changes, we first push the staging context (in
FilesController.EnterFile), and then later we push the stagingSecondary context
when we realize we only have staged changes. This leaves the highlight of the
staging context on.
runewidth.StringWidth is an expensive call, even if the input string is pure
ASCII. Improve this by providing a wrapper that short-circuits the call to len
if the input is ASCII.
Benchmark results show that for non-ASCII strings it makes no noticable
difference, but for ASCII strings it provides a more than 200x speedup.

In d5b4f7bb3e and 58a83b0862 we introduced a combined mechanism for rerendering
views when either their width changes (needed for the branches view which
truncates long branch names), or the screen mode (needed for those views that
display more information in half or full screen mode, e.g. the commits view).
This was a bad idea, because it unnecessarily rerenders too many views when just
their width changes, which causes a noticable lag. This is a problem, for
example, when selecting a file in the files panel that has only unstaged
changes, and then going to one that has both staged and unstaged changes; this
splits the main view, causing the side panels to become a bit narrower, and
rerendering all those views took almost 500ms on my machine. Another similar
example is entering or leaving staging mode.
Fix this by being more specific about which views need rerendering under what
conditions; this improves the time it takes to rerender in the above scenarios
from 450-500s down to about 20ms.
This reintroduces the code that was removed in 58a83b0862, but in a slightly
different way.
The rendering of remote branches is in no way dependent on the width of the view
(or the screen mode). Unlike in the local branches view, we don't truncate long
branch names here (because there's no more information after them).
This is an error introduced in d5b4f7bb3e.
For checkboxes it probably doesn't really make sense to use them yet, because
we'd have to find a way how you can toggle them without closing the dialog; but
we already provide rendering for them to lay the ground.
But radio buttons can be used already, because for those it is ok to close the
dialog when choosing a different option (as long as there is only one grounp of
radio buttons in the panel, that is).
Strike it through if not applicable. This will hopefully help with confusion
about the meaning of "all" in the "Discard all changes" entry; some people
misunderstand this to mean all changes in the working copy. Seeing the "Discard
unstaged changes" item next to it hopefully makes it clearer that "all" is meant
in contrast to that.
Several custom patch commands on parts of an added file would fail with the
confusing error message "error: new file XXX depends on old contents". These
were dropping the custom patch from the original commit, moving the patch to a
new commit, moving it to a later commit, or moving it to the index.
We fix this by converting the patch header from an added file to a diff against
an empty file. We do this not just for the purpose of applying the patch, but
also for rendering it and copying it to the clip board. I'm not sure it matters
much in these cases, but it does feel more correct for a filtered patch to be
presented this way.
We're going to add another argument in the next commit, and that's getting a bit
much, especially when most of the arguments are bool and you only see true and
false at the call sites without knowing what they mean.
This is important when using a pager that draws a horizontal line across the
entire width of the view; when changing from a file or directory that has only
unstaged (or only staged) changes to one that has both, the main view is split
in half, but the PTY task would be run on the view in its old state, so the
horizonal line would be too long and wrap around.
All PTYs were created with the size of the main view, on the assumption that
main and secondary always have the same size. That's not true though; in
horizontal split mode, the width of the two views can differ by one because of
rounding, and when using a pager that draws a horizontal line across the width
of the view, this is visible and looks very ugly.
When switching to a repo that was open before, the context tree is reused, so
before adding keybinding functions to those contexts again, we need to clear the
old ones.
