The previous scrollbars were too chunky and encroached too much on a view's content.
The new ones are slim and right-aligned so they encroach into dead space between views
which is much better
- **PR Description**
Adds support for selecting a range of files and adding them to a custom
patch. Closes#3251
The behavior for node selection is the same as used in #3248 because I
copied the approach. Please let me know if there's a mismatch or if
something else is preferred.
I also copied `normalisedSelectedNodes` and
`isDescendentOfSelectedNodes` verbatim, just adapted their signature
types.
It seems like we could share those two functions between
`[]*filetree.CommitFileNode` and `[]*filetree.FileNode` by making those
functions like `func normalisedSelectedCommitNodes[T any](selectedNodes
[]*filetree.Node[T]) []*filetree.Node[T]`. That would require calling
them with a `lo.Map(...)` which returns `node.GetRaw()`, and I feel
weird about giving a different type back to the calling function.
I added a couple of test cases, and all of the existing patch tests pass
for me, but please do let me know if there are any other test cases I
should add.

Before this commit, we had pkg/integration/tests/submodule/add.go
failing with a panic. I'm pretty sure the issue is this: we're now
calling quite a few GetDisabledReason calls on each layout() call,
and if a background thread happens to update a model slice while
we're doing this, we can end up with a selection index that's now
out of bounds because it hasn't been clamped to match the new list
length.
Specifically, here we had the selected index being -1 (the list starts
empty and somehow the value is -1 in this case) and then the list
gets a new submodule so the length is now 1, but the list cursor
doesn't know about this so remains on the old value. Then we confirm
the length is greater than zero and try to get the selected submodule
and get an out of bounds error.
This commit fixes the issue by clamping the selected index whenever
we get the length of the list so that it stays in-sync. This is not
a perfect solution because the length can change at any time, but
it seems to reliably fix the test, and using mutexes didn't seem to
make a difference.
Note that we're swapping the order of IFileTree and IListCursor in
the file tree view model to ensure that the list cursor's Len()
method is called (which performs the clamping).
Also, comment from the PR:
This 'trait' pattern we're using is convenient but can lead to awkward
situations. In this case we have both the list view model and the
(embedded) list cursor with a Len() method. The list cursor Len()
method just calls the list view model Len() method. But I wanted
to make it that the list view model now calls ClampSelection() on the
list cursor whenever it obtains the length. This will cause an
infinite loop because ClampSelection() internally calls Len()
(which calls the list view model's Len() method which in turn
calls ClampSelection() again, etc).
The only reason we were passing the list view model into the list
cursor was to supply the length method, so now we're just doing
that directly, and letting the list view model delegate the Len()
call to the list cursor, which now itself calls ClampSelection.
As part of making lazygit more discoverable, there are certain keys which you almost certainly
need to press when you're in a given mode e.g. 'v' to paste commits when cherry-picking. This
commit prominently shows these keybinding suggestions alongside the others in the option view.
I'm using the same colours for these keybindings as is associated with the mode elsewhere e.g.
yellow for rebasing and cyan for cherry-picking. The cherry-picking one is a bit weird because
we also use cyan text to show loaders and app status at the bottom left so it may be confusing,
but I haven't personally found it awkward from having tested it out myself.
Previously we would render these options whenever a new context was activated, but now that we
need to re-render options whenever a mode changes, I'm instead rendering them on each screen
re-render (i.e. in the layout function). Given how cheap it is to render this text, I think
it's fine performance-wise.
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.
We're going to be adding tooltips to the cheatsheet to better explain what each actions
does. As such, we're switching to a table format rather than a list.
I'm also changing how the keys are represented, using a markdown approach rather than
an html approach
- 's' for showing only staged files
- 'u' for showing only unstaged files
- 'r' for resetting the filter

I've thought about adding `disabled` reasons for them but they kinda
don't make sense since if there are only `unstaged` files, disabling the
`Show only staged files` makes no sense because the `Show only unstaged
files` shows nothing different so we should disable that too, and then
what's the point of having a menu if everything except for `reset` is
disabled.
As part of this, you must now press enter on a merge conflict file
to focus the merge view; you can no longer press space and if you do
it will raise an error.
Previously if we marked a line with IsSelected() we would check if it was selected, but
we would not check if other lines were unexpectedly selected. Now, if you use IsSelected(),
we ensure that _only_ the lines you marked as such are the selected lines.
Something dumb that we're currently doing is expecting list items
to define an ID method which returns a string. We use that when copying
items to clipboard with ctrl+o and when getting a ref name for diffing.
This commit gets us a little deeper into that hole by explicitly requiring
list items to implement that method so that we can easily use the new
helper functions in list_controller_trait.go.
In future we need to just remove the whole ID thing entirely but I'm too
lazy to do that right now.

Show unstaged file names in default colour
Previously, we had the following rules:
* file names were in red when unstaged or partially staged
* directory names were in red if unstaged, yellow if partially staged,
and
green if fully staged
Red text on a black background can be hard to read, so instead I'm
changing it
so that unstaged files have their names in the default text colour.
I'm also making it so that partially staged files are in yellow, just
like how
partially staged directories are yellow (same deal with the commit files
view
when adding to a custom patch).
So the new rules are:
* unstaged files/directories use the default colour
* partially staged files/directories are in yellow
* fully staged files/directories are in green
I've also done a refactor on the code clean up some dead code from when
the file tree
outline was drawn with box characters, and I've made it so that the
indentation in
each line is handled inside the function that draws the line rather than
in the recursive
parent function. This makes it easier to experiment with things like
showing the file
status characters on the left edge of the view (admittedly after
experimenting with it,
I decided I didn't like it). Apologies for having a refactor and a
functional change
in the one commit but by the time I was done, I couldn't be bothered
going back and
retroactively splitting it into two halves.

- **PR Description**
Issue: https://github.com/jesseduffield/lazygit/issues/3196
This PR adds the ability to select a range of items in list contexts. It
does this in two ways:
* Sticky range select: like what we already have in the staging view,
you press 'v' to toggle range select and then use up/down keys to extend
the range
* Non-sticky range select: rather than explicitly toggling this on/off,
you use shift+up/down to extend the range
The PR adds the ability to range select in all list contexts, but it's
up to individual actions to opt-in to supporting a range. This PR only
supports it for copying a range of commits for cherry-picking. We can
add more support iteratively so that we're not merging a single giant
PR. For all actions requiring selection of a single-item, an error will
be shown if a range is selected.
Other use cases we want to support in the near future:
* marking commits as pick/drop/fixup/squash/etc when mid-rebase
* fixup/squash/drop when outside rebase
* moving commits up/down (in or out of rebase)
* staging/unstaging multiple files
* discarding multiple files
## Updated keybindings
Because the 'v' binding is now globally dedicated to toggling range
select, I've changed the cherry-pick copy/paste keys from 'c' and 'v' to
'shift+C' and 'shift+V' respectively. I've also nullified the 'v'
keybinding on the 'view divergence from upstream' option in the upstream
options menu (conveniently it was the first option in the menu so you
can press enter on it).
## Standardised range select display
As a bonus, this PR standardises how we display a range select. We
already had range select support in the patch explorer view and merge
conflicts view, but they were directly rendering the highlighted
selection (i.e. blue background colour) in the content written to the
view, rather than tell the view which lines were selected and have the
view highlight them itself. A convenient benefit here is that now the
entire line is highlighted, including trailing space, rather than just
the content of the line. Another convenient benefit is that our
integration tests can now easily ask the view which lines are selected,
rather than depending on the specific context, because the view keeps
track of it.
I've removed the selectedRangeBgColor config option because
selectedLineBgColor should be fine. I don't see the need for two
options, but tell me if you think otherwise.
Also, another thing we're standardising on: hitting escape will cancel
the range select, which in the staging/patch-building views means if
you're selecting a range, you'll need to hit escape twice to exit out of
the view. For consistency, we're also applying this logic if you have a
hunk selected. I personally would much prefer this and have several
times accidentally exited out of the view when trying to cancel a range
select by pressing escape. In lazygit in general, 'escape' means 'exit
out of the innermost mode' and I would consider range select to be a
kind of mode.
## Sticky vs non-sticky range interaction
Here's the state machine that explains how the sticky and non-sticky
range select modes interact. Although users will typically pick one or
the other, it's important to be clear on what the logic is if you swap
between them:
```
(no range, press 'v') -> sticky range
(no range, press arrow) -> no range
(no range, press shift+arrow) -> nonsticky range
(sticky range, press 'v') -> no range
(sticky range, press arrow) -> sticky range
(sticky range, press shift+arrow) -> nonsticky range
(nonsticky range, press 'v') -> no range
(nonsticky range, press arrow) -> no range
(nonsticky range, press shift+arrow) -> nonsticky range
```
Also if you press escape in either range mode, it cancels the range
select.
## Some implementation details
* when the action involves toggling e.g. toggling cherry-pick copy or
toggling staged, we decide what to do based on the selection: for
example with staging: if there are any unstaged changes in the
selection, we'll stage everything, otherwise we unstage everything. This
is the logic we already had when staging individual directories.
* we retain range selection if a view loses focus
* where we previously set SetSelectedLineIdx all over the place (e.g.
setting selected line idx to 0 when checking out a branch) we're now
using SetSelection which also resets the range select. There are only a
couple of places where we would still want to use SetSelectedLineIdx
(e.g. when the user moves up/down a page, because they would want to
retain range select in that case)

Often if a test fails and there's an unaknowledged toast message, that message will
explain why the test failed. Given that we don't display toast messages in
integration tests when they run (for reasons I can't recall right now), we need to
log it as part of the error message.
We don't need it there so no need to enable it.
I'm leaving the disabled reason checks there, even though they're now redundant,
because they're only one-liners and they communicate intent.
We want to show an error when the user tries to invoke an action that expects only
a single item to be selected.
We're using the GetDisabledReason field to enforce this (as well as DisabledReason
on menu items).
I've created a ListControllerTrait to store some shared convenience functions for this.
This requires us to change the 'v' keybinding for paste to something else,
now that 'v' is used globally for toggling range select. So I'm using
'shift+v' and I'm likewise changing 'c' to 'shift+c' for copying, so
that they're consistent.
We will need to clearly communicate this change in keybindings.
The only time we should call SetSelectedLineIdx is when we are happy for a
select range to be retained which means things like moving the selected line
index to top top/bottom or up/down a page as the user navigates.
But in every other case we should now call SetSelection because that will
set the selected index and cancel the range which is almost always what we
want.
This is the highest priority of the escape actions because it's the thing you're
most likely to want to do upon hitting escape if you have a range selected.
Applying this to the staging/patch-building views is tricky: if we want this logic
for when a range of lines is selected, we'll also need to apply it when a hunk
is selected too. I still think it's worth it though: I've often accidentally
escaped from the staging view when trying to cancel a range selection.
We're not fully standardising here: different contexts can store their range state however
they like. What we are standardising on is that now the view is always responsible for
highlighting the selected lines, meaning the context/controller needs to tell the view
where the range start is.
Two convenient benefits from this change:
1) we no longer need bespoke code in integration tests for asserting on selected lines because
we can just ask the view
2) line selection in staging/patch-building/merge-conflicts views now look the same as in
list views i.e. the highlight applies to the whole line (including trailing space)
I also noticed a bug with merge conflicts not rendering the selection on focus though I suspect
it wasn't a bug with any real consequences when the view wasn't displaying the selection.
I'm going to scrap the selectedRangeBgColor config and just let it use the single line
background color. Hopefully nobody cares, but there's really no need for an extra config.
This adds range select ability in two ways:
1) Sticky: like what we already have with the staging view i.e. press v then use arrow keys
2) Non-sticky: where you just use shift+up/down to expand the range
The state machine works like this:
(no range, press 'v') -> sticky range
(no range, press arrow) -> no range
(no range, press shift+arrow) -> nonsticky range
(sticky range, press 'v') -> no range
(sticky range, press arrow) -> sticky range
(sticky range, press shift+arrow) -> nonsticky range
(nonsticky range, press 'v') -> no range
(nonsticky range, press arrow) -> no range
(nonsticky range, press shift+arrow) -> nonsticky range
CI is erroneously saying that our integration tests are passing.
As @stefanhaller says in a comment:
> It broke with this commit:
https://github.com/jesseduffield/lazygit/commit/aaecd6cc40d8ffe07eb3c2cdbed5bf908787bc8b.
Since that change, the run_integration_tests.sh script will exit with
the exit status of the the last mv command, not the test run. Should be
pretty easy to fix.
Thanks to Stefan for fixing this
(The reason I'm saying this all here in the PR description is that PR
descriptions now get included in merge commits)
Previously we included all navigation keybindings from all views in the keybindings menu, meaning
if you pressed enter on 'next page' in the commits view, you'd end up triggering the action
in the sub-commits view.
- **PR Description**
Addresses #3116.
I'm not 100% sure I like the behavior, but I put it out there so that
others can test it and form an opinion. It not only affects keybindings,
but also invoking menu items (either with enter or with their key
binding): the menu now stays open in that case, which I think is
actually better.
There's a horrible hack for keeping the integration tests working, I
don't have a good idea how to fix that for real. Suggestions welcome.
- **PR Description**
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.

Because we obtain disabled reasons after every action, we need to keep the code for doing so
super fast. As such, we should not be hitting the filesystem to get rebase state, instead
we should just get the cached state.
I feel like we should actually be using the cached state everywhere like we do with all
our other models if only for the sake of consistency.

We need to fetch our list of tests both outside of our test binary and
within. We need to get the list from within so that we can run the code
that drives the test and runs assertions. To get the list of tests we
need to know where the root of the lazygit repo is, given that the tests
live in files under that root.
So far, we've used this GetLazyRootDirectory() function for that, but it
assumes that we're not in a test directory (it just looks for the first
.git dir it can find). Because we didn't want to properly fix this
before, we've been setting the working directory of the test command to
the lazygit root, and using the --path CLI arg to override it when the
test itself ran. This was a terrible hack.
Now, we're passing the lazygit root directory as an env var to the
integration test, so that we can set the working directory to the actual
path of the test repo; removing the need to use the --path arg.

know what's going on there. At any rate, I'm just going to get the test passing by passing `-f=filterFile` as a single argument.

The output of the GetWindowDimensions function is hard to understand just by looking at it,
so I've added a helper function in the tests to render the window layout as text, so that
in order to create a new test you just come up with some args and paste the output as the
expected output.
This has the same downsides that any snapshot-based testing has: it's more brittle than
targeted assertions. But it is much easier to make sense of these snapshots than it is
to make sense of more fine-grained assertions, and I like the fact that these tests can
serve as documentation.
We are also removing the single-character padding on the left/right edges of the bottom
line because it's unnecessary
Unfortunately we need to create views for each spacer: it's not enough to just
layout the existing views with padding inbetween because gocui only renders
views meaning if there is no view in a given position, that position will just
render whatever was there previously (at least that's what I recall from talking
this through with Stefan: I could be way off).

This PR captures the code coverage from our unit and integration tests. At the
moment it simply pushes the result to Codacy, a platform that assists with
improving code health. Right now the focus is just getting visibility but I want
to experiment with alerts on PRs when a PR causes a drop in code coverage.
To be clear: I'm not a dogmatist about this: I have no aspirations to get to
100% code coverage, and I don't consider lines-of-code-covered to be a perfect
metric, but it is a pretty good heuristic for how extensive your tests are.
The good news is that our coverage is actually pretty good which was a surprise
to me!
As a conflict of interest statement: I'm in Codacy's 'Pioneers' program which
provides funding and mentorship, and part of the arrangement is to use Codacy's
tooling on lazygit. This is something I'd have been happy to explore even
without being part of the program, and just like with any other static analysis
tool, we can tweak it to fit our use case and values.
## How we're capturing code coverage
This deserves its own section. Basically when you build the lazygit binary you
can specify that you want the binary to capture coverage information when it
runs. Then, if you run the binary with a GOCOVERDIR env var, it will write
coverage information to that directory before exiting.
It's a similar story with unit tests except with those you just specify the
directory inline via `-test.gocoverdir`.
We run both unit tests and integration tests separately in CI, _and_ we run them
parallel with different OS's and git versions. So I've got each step uploading
the coverage files as an artefact, and then in a separate step we combine all
the artefacts together and generate a combined coverage file, which we then
upload to codacy (but in future we can do other things with it like warn in a PR
if code coverage decreases too much).
Another caveat is that when running integration tests, not only do we want to
obtain code coverage from code executed by the test binary, we also want to
obtain code coverage from code executed by the test runner. Otherwise, for each
integration test you add, the setup code (which is run by the test runner, not
the test binary) will be considered un-covered and for a large setup step it may
appear that your PR _decreases_ coverage on net. Go doesn't easily let you
exclude directories from coverage reports so it's better to just track the
coverage from both the runner and the binary.
The binary expects a GOCOVERDIR env var but the test runner expects a
test.gocoverdir positional arg and if you pass the positional arg it will
internally overwrite GOCOVERDIR to some random temp directory and if you then
pass that to the test binary, it doesn't seem to actually write to it by the
time the test finishes. So to get around that we're using LAZYGIT_GOCOVERDIR and
then within the test runner we're mapping that to GOCOVERDIR before running the
test binary. So they both end up writing to the same directory. Coverage data
files are named to avoid conflicts, including something unique to the process,
so we don't need to worry about name collisions between the test runner and the
test binary's coverage files. We then merge the files together purely for the
sake of having fewer artefacts to upload.
## Misc
Initially I was able to have all the instances of '/tmp/code_coverage' confined
to the ci.yml which was good because it was all in one place but now it's spread
across ci.yml and scripts/run_integration_tests.sh and I don't feel great about
that but can't think of a way to make it cleaner.
I believe there's a use case for running scripts/run_integration_tests.sh
outside of CI (so that you can run tests against older git versions locally) so
I've made it that unless you pass the LAZYGIT_GOCOVERDIR env var to that script,
it skips all the code coverage stuff.
On a separate note: it seems that Go's coverage report is based on percentage of
statements executed, whereas codacy cares more about lines of code executed, so
codacy reports a higher percentage (e.g. 82%) than Go's own coverage report
(74%).
I applied to the Codacy Pioneers program for funding and mentorship and I got accepted. Part of the terms is to show the codacy report badge in the readme. Thank God it's an A!
This is pretty funny: the staticcheck linter gets mad if we use a field which is marked
in a comment as being deprecated. But it tripped on my own comment saying that a field
is deprecated in terms of the user config!
Obviously we have to make use of this field, otherwise we would just remove it entirely
rather than mark it as deprecated, so I'm silencing this lint.
I doubt this lint would actually come in handy in other cases (like when using a third
party package) and worst case scenario we just end up fixing the problem when we
try to upgrade the package and the deprecated field is now gone).
We're going to make this user config struct a more authoritative source of truth.
Some of these fields weren't actually explained anywhere so I've added explanations.
In places where a lot of explanation is required I've linked to existing explanations in other docs.
Previously there was no way to render a view's search status without also moving the cursor
to the current search match. This caused issues where we wanted to display the status
after leaving the view and coming back, or when beginning a new search from within the
view.
This commit separates the two use cases so we only move the cursor when we're actually
selecting the next search match
This spares me effort when it comes to making release notes.
Yes, sometimes it may be easier to start a message without an imperative e.g. 'When X happens, do Y'
but I don't want to overwhelm the contributor with details.
