A commits refresh does its git work on a worker and then reads the model,
the contexts, and the modes for that work directly from there:
LocalCommits.GetSelectionRangeAndMode/GetLimitCommits/GetShowWholeGitGraph,
Model.Commits/MainBranches/HashPool, the filtering path/author. Those are
owned by the UI thread, which is concurrently running the cursor and render
code, so the reads race it — the dominant, confirmed source of the
commits-scope flakes (the startup ClampSelection vs GetSelectionRangeAndMode
race, for one).
Gather them into an immutable capturedCommitState on the UI thread, before
the git work is dispatched, and have refreshCommitsWithLimit compute from
that snapshot. UI-thread callers capture inline; worker callers can't (a
SYNC/BLOCK_UI refresh parks the UI thread at wg.Wait, so hopping from a
scope sub-worker would deadlock), so the capture is lifted out of the scope
worker into the refresh orchestration, and worker callers announce
themselves with a new RefreshFromWorker entry point that hops the capture to
the UI thread and blocks for it (OnUIThreadAndWait). BLOCK_UI runs the whole
refresh on the UI thread regardless of the caller, so it captures inline
too.
Every refresh issued from a worker that reaches the commits (or branches,
which pulls in commits) scope is converted: the fast-forward, branch/tag
delete, worktree remove/detach, push, reword-via-rebase, author edits,
custom-command, hard-reset-with-autostash, reset-to-ref, fetch-and-checkout,
gpg-stream, post-fetch, and external-change-poller refreshes, plus the
branch checkout and move-commits-to-new-branch refreshes.

When conflicts of an in-progress rebase/merge/cherry-pick/revert are
resolved, lazygit pops up a prompt offering to continue it. This is
helpful when you started the operation in lazygit and resolved the
conflicts in your editor. But it's confusing when the operation was
started outside lazygit — e.g. by a coding agent in another terminal
that resolves the conflicts but hasn't continued yet because it's still
running tests or fixing the build. lazygit would then prompt unbidden.
Track whether the in-progress operation was started from within lazygit,
and only show the prompt in that case. We record this right after running
a merge/rebase step (in CheckMergeOrRebaseWithRefreshOptions, the
subprocess branch of genericMergeCommand, and the custom-command
conflict path), and clear it whenever a refresh observes that no
operation is in progress — which also handles an operation that was
finished or aborted externally.
The conflict-resolution tests start their operation by running git
directly (not through lazygit's UI), so they call the new test helper
Common.PretendMergeOrRebaseStartedInLazygit to have lazygit treat the
operation as its own and still get the prompt.

CustomCommand.Key and CustomCommandMenuOption.Key are user-configured
keybindings just like the built-in ones. Converting them to the Keybinding type
lets a user assign multiple keys to the same custom command, e.g. `key: [a, b]`,
the same way they would for any other keybinding.
The validator iterates over the elements rather than checking a single string,
the binding registration goes through GetValidatedKeyBindingKeys to register
every alternate, and the existing error messages use .String() so a multi-key
binding renders sensibly.
CustomCommandPrompt.Key (a form field name, not a keybinding) stays a plain
string.
This is a pure refactor in preparation for letting users configure multiple
alternate bindings for a single command. Every Binding still has exactly one
key, so nothing changes visibly: the cheatsheet, the on-screen options bar,
and the keybindings menu all render identically.
When a Binding ends up with multiple keys, the on-screen options bar will
show only the first (to avoid clutter); the cheatsheet will show all of them (in
a later commit). For now both paths take Key[0].
MenuItem.Key is changed in the same way, it also has a slice of keys now.
In this commit we keep the name `Key` in Binding, KeybindingOpts and MenuItem,
instead of renaming them to `Keys` right away, in order to keep the diff a bit
more readable. We'll do the rename separately in the next commit.
Modifiers were moved into Key in 22169e22f, but the separate Modifier field
on types.Binding and gocui.keybinding was left behind. The keypress matcher
already compares modifiers via Key.Equals, so the old field is never read on
the dispatch path; it just got passed through SetKeybinding and stored.
Drop it from gocui.keybinding, types.Binding, and the SetKeybinding /
DeleteKeybinding signatures, and remove every now-redundant Modifier:
gocui.ModNone struct field. Mouse bindings keep their own Modifier (on
ViewMouseBinding) since that path still consults it.
I copied all files except dot files (.github and .gitignore), the _examples
folder, and go.mod/go.sum.
At some point we may want to copy the files back to the gocui repo when other
clients (e.g. lazydocker) want to use the newer versions of them.
When building multi-step custom command forms, some prompts are only
relevant depending on earlier answers. Without conditional logic,
users must dismiss irrelevant prompts manually.
Prompts now accept a `condition` field with a template expression
evaluated against prior form values. Skipped prompts default to
an empty string.
The template expression is a string pre- and suffixed with double curly
braces - {{}}.
Form keys can be reused, a guard ensures that skipped prompts do not
reset already set form keys with an empty string. This allows the
conditional flow to remind a user to set a key that was left empty
because additional conditions want that key to be set. This removes the
need to have additional if checks in the command that uses the form
keys.
This doesn't really solve a pressing problem, because I guess it's unlikely that
users add spaces at the beginning or end of what they type into a prompt; but it
could happen, and in this case we almost always want to strip it. Just adding
this here for completeness while I was working on this code.
The only exception is the input prompt of custom commands, because who knows
what users want to use that input for in their custom command.
Most of our prompts don't (shouldn't) allow empty input, but most callers didn't
check, and would run into cryptic errors when the user pressed enter at an empty
prompt (e.g. when creating a new branch). Now we simply don't allow hitting
enter in this case, and show an error toast instead.
This behavior is opt-out, because there are a few cases where empty input is
supported (e.g. creating a stash).
Introduce the 'SelectedSubmodule' struct and allow using it as a
placeholder value.
Add a corresponding test.
Update the documentation to include it among the listed placeholder
values.
Refresh is one of those functions that shouldn't require error handling (similar
to triggering a redraw of the UI, see
https://github.com/jesseduffield/lazygit/issues/3887).
As far as I see, the only reason why Refresh can currently return an error is
that the Then function returns one. The actual refresh errors, e.g. from the git
calls that are made to fetch data, are already logged and swallowed. Most of the
Then functions do only UI stuff such as selecting a list item, and always return
nil; there's only one that can return an error (updating the rebase todo file in
LocalCommitsController.startInteractiveRebaseWithEdit); it's not a critical
error if this fails, it is only used for setting rebase todo items to "edit"
when you start an interactive rebase by pressing 'e' on a range selection of
commits. We simply log this error instead of returning it.
This makes it possible to use date and time in initial values like this:
```yaml
initialValue: 'ruudk/{{ runCommand "date +\"%Y/%-m\"" }}/'
```
I want to use this to configure my BranchPrefix like this:
```yaml
git:
branchPrefix: 'ruudk/{{ runCommand "date +\"%Y/%-m\"" }}/'
```
It has fields .To and .From (the hashes of the last and the first selected
commits, respectively), and it is useful for creating git commands that act on a
range of commits.
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.
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.
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).
It can optionally be used to set the title of the panel that shows the output of
a command (when showOutput is true). If left unset, the command string is used
as the title.
In a triangular workflow the branch that you're pulling from is not the same as
the one that you are pushing to. For example, some people find it useful to set
the upstream branch to origin/master so that pulling effectively rebases onto
master, and set the push.default git config to "current" so that "feature"
pushes to origin/feature.
Another example is a fork-based workflow where "feature" has upstream set to
upstream/main, and the repo has remote.pushDefault set to "origin", so pushing
on "feature" pushes to origin/feature.
This commit adds new fields to models.Branch that store the ahead/behind
information against the push branch; for the "normal" workflow where you pull
and push from/to the upstream branch, AheadForPush/BehindForPush will be the
same as AheadForPull/BehindForPull.
This guards against accidentally renaming a model field and thereby breaking
user's custom commands. With this change we'll get a build failure when we do
that.
In go 1.22, loop variables are redeclared with each iteration of the
loop, rather than simple updated on each iteration. This means that we
no longer need to manually redeclare variables when they're closed over
by a function.
Sometimes it takes a while to get PRs accepted upstream, and this blocks our
progress. Since I'm pretty much the only one making changes there anyway, it
makes sense to point to my fork directly.
We've been sometimes using lo and sometimes using my slices package, and we need to pick one
for consistency. Lo is more extensive and better maintained so we're going with that.
My slices package was a superset of go's own slices package so in some places I've just used
the official one (the methods were just wrappers anyway).
I've also moved the remaining methods into the utils package.
We have a use-case to rebind 'm' to the merge action in the branches panel. There's three ways to handle this:
1) For all global keybindings, define a per-panel key that invokes it
2) Give a name to all controller actions and allow them to be invoked in custom commands
3) Allow checking for merge conflicts after running a custom command so that users can add their own 'git merge' custom command
that matches the in-built action
Option 1 is hairy, Option 2 though good for users introduces new backwards compatibility issues that I don't want to do
right now, and option 3 is trivially easy to implement so that's what I'm doing.
I've put this under an 'after' key so that we can add more things later. I'm imagining other things like being able to
move the cursor to a newly added item etc.
I considered always running this hook by default but I'd rather not: it's matching on the output text and I'd rather something
like that be explicitly opted-into to avoid cases where we erroneously believe that there are conflicts.
The global counter approach is easy to understand but it's brittle and depends on implicit behaviour that is not very discoverable.
With a global counter, if any goroutine accidentally decrements the counter twice, we'll think lazygit is idle when it's actually busy.
Likewise if a goroutine accidentally increments the counter twice we'll think lazygit is busy when it's actually idle.
With the new approach we have a map of tasks where each task can either be busy or not. We create a new task and add it to the map
when we spawn a worker goroutine (among other things) and we remove it once the task is done.
The task can also be paused and continued for situations where we switch back and forth between running a program and asking for user
input.
In order for this to work with `git push` (and other commands that require credentials) we need to obtain the task from gocui when
we create the worker goroutine, and then pass it along to the commands package to pause/continue the task as required. This is
MUCH more discoverable than the old approach which just decremented and incremented the global counter from within the commands package,
but it's at the cost of expanding some function signatures (arguably a good thing).
Likewise, whenever you want to call WithWaitingStatus or WithLoaderPanel the callback will now have access to the task for pausing/
continuing. We only need to actually make use of this functionality in a couple of places so it's a high price to pay, but I don't
know if I want to introduce a WithWaitingStatusTask and WithLoaderPanelTask function (open to suggestions).
