Jesse Duffield aaecd6cc40 Add coverage arg for integration tests
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%).

Elevator Pitch

Rant time: You've heard it before, git is powerful, but what good is that power when everything is so damn hard to do? Interactive rebasing requires you to edit a goddamn TODO file in your editor? Are you kidding me? To stage part of a file you need to use a command line program to step through each hunk and if a hunk can't be split down any further but contains code you don't want to stage, you have to edit an arcane patch file by hand? Are you KIDDING me?! Sometimes you get asked to stash your changes when switching branches only to realise that after you switch and unstash that there weren't even any conflicts and it would have been fine to just checkout the branch directly? YOU HAVE GOT TO BE KIDDING ME!

If you're a mere mortal like me and you're tired of hearing how powerful git is when in your daily life it's a powerful pain in your ass, lazygit might be for you.

Features

Stage individual lines

Press space on the selected line to stage it, or press v to start selecting a range of lines. You can also press a to select the entirety of the current hunk.

stage_lines

Interactive Rebase

Press e on a commit to start an interactive rebase on it: causing all above commits to become part of the TODO file. Then squash (s), fixup (f), drop (d), edit (e), move up (ctrl+i) or move down (ctrl+j) any of TODO commits, before continuing the rebase by bringing up the rebase options menu with m and then selecting continue. You can also perform any these actions as a once-off (e.g. pressing s on a commit to squash it) without explicitly starting a rebase.

interactive_rebase

Cherry-pick

Press c on a commit to copy it and press v to paste (cherry-pick) it.

cherry_pick

Bisect

Press b in the commits view to mark a commit as good/bad in order to begin a git bisect.

bisect

Nuke the working tree

For when you really want to just get rid of anything that shows up when you run git status (and yes that includes dirty submodules) kidpix style, press shift+d to bring up the reset options menu and then select the 'nuke' option.

Nuke working tree

Amend an old commit

Pressing shift+a on any commit will amend that commit with the currently staged changes (running an interactive rebase in the background).

amend_old_commit

Filter

You can filter a view with /. Here we filter down our branches view and then hit enter to view its commits.

filter

Invoke a custom command

Lazygit has a very flexible custom command system. In this example a custom command is defined which emulates the built-in branch checkout action.

custom_command

Worktrees

You can create worktrees to have multiple branches going at once without the need for stashing or creating WIP commits when switching between them. Press w in the branches view to create a worktree from the selected branch and switch to it.

worktree_create_from_branches

Rebase magic (custom patches)

You can build a custom patch from an old commit and then remove the patch from the commit, split out a new commit, apply the patch in reverse to the index, and more.

In this example we have a redundant comment that we want to remove from an old commit. We hit <enter> on the commit to view its files, then <enter> on a file to focus the patch, then <space> to add the comment line to our custom patch, and then ctrl+p to view the custom patch options; selecting to remove the patch from the current commit.

Learn more in the Rebase magic Youtube tutorial.

custom_patch

Rebase from marked base commit

Say you're on a feature branch that was itself branched off of the develop branch, and you've decided you'd rather be branching off the master branch. You need a way to rebase only the commits from your feature branch. In this demo we check to see which was the last commit on the develop branch, then press shift+b to mark that commit as our base commit, then press r on the master branch to rebase onto it, only bringing across the commits from our feature branch. Then we push our changes with shift+p.

rebase_onto

Undo

You can undo the last action by pressing 'z' and redo with ctrl+z. Here we drop a couple of commits and then undo the actions. Undo uses the reflog which is specific to commits and branches so we can't undo changes to the working tree or stash.

undo

Commit graph

When viewing the commit graph in an enlarged window (use + and _ to cycle window sizes), the commit graph is shown. Colours correspond to the commit authors, and as you navigate down the graph, the parent commits of the selected commit are highlighted.

commit_graph

Compare two commits

If you press shift+w on a commit (or branch/ref) a menu will open that allows you to mark that commit so that any other commit you select will be diffed against it. Once you've selected the second commit, you'll see the diff in the main view and if you press <enter> you'll see the files of the diff. You can press shift+w to view the diff menu again to see options like reversing the diff direction or exiting diff mode. You can also exit diff mode by pressing <escape>.

You can either add the overlay to your system and install lazygit as usual:

sudo eselect repository enable cova
sudo emaint sync -r cova
sudo emerge dev-vcs/lazygit

Or you can download the ebuild and install it manually; please consider the example below just as a suggestion to be adapted to your system.

su
LAZYGIT_VERSION="0.39.3" # Replace with the version you want from cova-overlay
cd /usr/overlay/dev-vcs/ # Replace your overlay path
mkdir lazygit
cd lazygit

Manual

You'll need to install Go

git clone https://github.com/jesseduffield/lazygit.git
cd lazygit
go install

You can also use go run main.go to compile and run in one go (pun definitely intended)

Usage

Call lazygit in your terminal inside a git repository.

$ lazygit

If you want, you can also add an alias for this with echo "alias lg='lazygit'" >> ~/.zshrc (or whichever rc file you're using).

Keybindings

You can check out the list of keybindings here.

Changing Directory On Exit

If you change repos in lazygit and want your shell to change directory into that repo on exiting lazygit, add this to your ~/.zshrc (or other rc file):

lg()
{
    export LAZYGIT_NEW_DIR_FILE=~/.lazygit/newdir

    lazygit "$@"

    if [ -f $LAZYGIT_NEW_DIR_FILE ]; then
            cd "$(cat $LAZYGIT_NEW_DIR_FILE)"
            rm -f $LAZYGIT_NEW_DIR_FILE > /dev/null
    fi
}

Then source ~/.zshrc and from now on when you call lg and exit you'll switch directories to whatever you were in inside lazygit. To override this behaviour you can exit using shift+Q rather than just q.
