### Build tags
You can use the following build tags:
#### `urfave_cli_no_docs`
When set, this removes `ToMarkdown` and `ToMan` methods, so your application
won't be able to call those. This reduces the resulting binary size by about
300-400 KB (measured using Go 1.18.1 on Linux/amd64), due to less dependencies.
### GOPATH

released version of Go on OS X and Windows. This project uses Github Actions for

## Contributing
Use @urfave/cli to ping the maintainers.
Welcome to the `urfave/cli` contributor docs! This goal of this document is to help those
interested in joining the 200+ humans who have contributed to this project over the years.
Feel free to put up a pull request to fix a bug or maybe add a feature. We will
give it a code review and make sure that it does not break backwards
compatibility. If collaborators agree that it is in line with
the vision of the project, we will work with you to get the code into
a mergeable state and merge it into the main branch.
> As a general guiding principle, the current maintainers may be notified via the
> @urfave/cli GitHub team.
If you have contributed something significant to the project, we will most
likely add you as a collaborator. As a collaborator you are given the ability
to merge others pull requests. It is very important that new code does not
break existing code, so be careful about what code you do choose to merge.
All of the current maintainers are *volunteers* who live in various timezones with
different scheduling needs, so please understand that your contribution or question may
not get a response for many days.
If you feel like you have contributed to the project but have not yet been added
as a collaborator, we probably forgot to add you :sweat_smile:. Please open an
issue!
### semantic versioning adherence
The `urfave/cli` project strives to strictly adhere to [semantic
versioning](https://semver.org/spec/v2.0.0.html). The active development branches and the
milestones and import paths to which they correspond are:
#### `main` branch
<https://github.com/urfave/cli/tree/main>
The majority of active development and issue management is targeting the `main` branch,
which **MUST** *only* receive bug fixes and feature *additions*.
- :arrow_right: [`v2.x`](https://github.com/urfave/cli/milestone/16)
- :arrow_right: `github.com/urfave/cli/v2`
The `main` branch in particular includes tooling to help with keeping the `v2.x` series
backward compatible. More details on this process are in the development workflow section
below.
#### `v1` branch
<https://github.com/urfave/cli/tree/v1>
The `v1` branch **MUST** only receive bug fixes in the `v1.22.x` series. There is no
strict rule regarding bug fixes to the `v2.x` series being backported to the `v1.22.x`
series.
- :arrow_right: [`v1.22.x`](https://github.com/urfave/cli/milestone/11)
- :arrow_right: `github.com/urfave/cli`
#### `v3-dev-main` branch
<https://github.com/urfave/cli/tree/v3-dev-main>
The `v3-dev-branch` **MUST** receive all bug fixes and features added to the `main` branch
and **MAY** receive feature *removals* and other changes that are otherwise
*backward-incompatible* with the `v2.x` series.
- :arrow_right: [`v3.x`](https://github.com/urfave/cli/milestone/5)
- unreleased / unsupported
### development workflow
Most of the tooling around the development workflow strives for effective
[dogfooding](https://en.wikipedia.org/wiki/Eating_your_own_dog_food). There is a top-level
`Makefile` that is maintained strictly for the purpose of easing verification of one's
development environment and any changes one may have introduced:
```sh
make
```
Running the default `make` target (`all`) will ensure all of the critical steps are run to
verify one's changes are harmonious in nature. The same steps are also run during the
[continuous integration
phase](https://github.com/urfave/cli/blob/main/.github/workflows/cli.yml).
In the event that the `v2diff` target exits non-zero, this is a signal that the public API
surface area has changed. If the changes adhere to semantic versioning, meaning they are
*additions* or *bug fixes*, then manually running the approval step will "promote" the
current `go doc` output:
```sh
make v2approve
```
Because the `generate` step includes updating `godoc-current.txt` and
`testdata/godoc-v2.x.txt`, these changes *MUST* be part of any proposed pull request so
that reviewers have an opportunity to also make an informed decision about the "promotion"
step.
#### generated code
A significant portion of the project's source code is generated, with the goal being to
eliminate repetetive maintenance where other type-safe abstraction is impractical or
impossible with Go versions `< 1.18`. In a future where the eldest Go version supported is
`1.18.x`, there will likely be efforts to take advantage of
[generics](https://go.dev/doc/tutorial/generics).
The built-in `go generate` command is used to run the commands specified in
`//go:generate` directives. Each such command runs a file that also supports a command
line help system which may be consulted for further information, e.g.:
```sh
go run internal/genflags/cmd/genflags/main.go --help
```
### pull requests
Please feel free to open a pull request to fix a bug or add a feature. The @urfave/cli
team will review it as soon as possible, giving special attention to maintaining backward
compatibility. If the @urfave/cli team agrees that your contribution is in line with the
vision of the project, they will work with you to get the code into a mergeable state,
merged, and then released.
### granting of commit bit / admin mode
Those with a history of contributing to this project will likely be invited to join the
@urfave/cli team. As a member of the @urfave/cli team, you will have the ability to fully
administer pull requests, issues, and other repository bits.
If you feel that you should be a member of the @urfave/cli team but have not yet been
added, the most likely explanation is that this is an accidental oversight! :sweat_smile:.
Please open an issue!

# Releasing urfave/cli
Releasing small batches often is [backed by
research](https://itrevolution.com/accelerate-book/) as part of the
virtuous cycles that keep teams and products healthy.
To that end, the overall goal of the release process is to send
changes out into the world as close to the time the commits were
merged to the `main` branch as possible. In this way, the community
of humans depending on this library are able to make use of the
changes they need **quickly**, which means they shouldn't have to
maintain long-lived forks of the project, which means they can get
back to focusing on the work on which they want to focus. This also
means that the @urfave/cli team should be able to focus on
delivering a steadily improving product with significantly eased
ability to associate bugs and regressions with specific releases.
## Process
- Release versions follow [semantic versioning](https://semver.org/)
- Releases are associated with **signed, annotated git tags**[^1].
- Release notes are **automatically generated**[^2].
In the `main` or `v1` branch, the current version is always
available via:
```sh
git describe --always --dirty --tags
```
**NOTE**: if the version reported contains `-dirty`, this is
indicative of a "dirty" work tree, which is not a great state for
creating a new release tag. Seek help from @urfave/cli teammates.
For example, given a described version of `v2.4.7-3-g68da1cd` and a
diff of `v2.4.7...` that contains only bug fixes, the next version
should be `v2.4.8`:
```sh
git tag -a -s -m 'Release 2.4.8' v2.4.8
git push origin v2.4.8
```
The tag push will trigger a GitHub Actions workflow. The remaining
steps require human intervention through the GitHub web view
although [automated solutions
exist](https://github.com/softprops/action-gh-release) that may be
adopted in the future.
- Open the [the new release page](https://github.com/urfave/cli/releases/new)
- At the top of the form, click on the `Choose a tag` select control and select `v2.4.8`
- In the `Write` tab below, click the `Auto-generate release notes` button
- At the bottom of the form, click the `Publish release` button
- :white_check_mark: you're done!
[^1]: This was not always true. There are many **lightweight git
tags** present in the repository history.
[^2]: This was not always true. The
[`docs/CHANGELOG.md`](./CHANGELOG.md) document used to be
manually maintained.
