# Contributing
|
||
|
||
Thank you for your interest in go-toml! We appreciate you considering
|
||
contributing to go-toml!
|
||
|
||
The main goal is the project is to provide an easy-to-use and efficient TOML
|
||
implementation for Go that gets the job done and gets out of your way – dealing
|
||
with TOML is probably not the central piece of your project.
|
||
|
||
As the single maintainer of go-toml, time is scarce. All help, big or small, is
|
||
more than welcomed!
|
||
|
||
## Ask questions
|
||
|
||
Any question you may have, somebody else might have it too. Always feel free to
|
||
ask them on the [discussion board][discussions]. We will try to answer them as
|
||
clearly and quickly as possible, time permitting.
|
||
|
||
Asking questions also helps us identify areas where the documentation needs
|
||
improvement, or new features that weren't envisioned before. Sometimes, a
|
||
seemingly innocent question leads to the fix of a bug. Don't hesitate and ask
|
||
away!
|
||
|
||

|
||
|
||
## Improve the documentation
|
||
|
||
The best way to share your knowledge and experience with go-toml is to improve
|
||
the documentation. Fix a typo, clarify an interface, add an example, anything
|
||
goes!
|
||
|
||
The documentation is present in the [README][readme] and thorough the source
|
||
code. On release, it gets updated on [pkg.go.dev][pkg.go.dev]. To make a change
|
||
to the documentation, create a pull request with your proposed changes. For
|
||
simple changes like that, the easiest way to go is probably the "Fork this
|
||
project and edit the file" button on Github, displayed at the top right of the
|
||
file. Unless it's a trivial change (for example a typo), provide a little bit of
|
||
context in your pull request description or commit message.
|
||
|
||
## Report a bug
|
||
|
||
Found a bug! Sorry to hear that :(. Help us and other track them down and fix by
|
||
reporting it. [File a new bug report][bug-report] on the [issues
|
||
tracker][issues-tracker]. The template should provide enough guidance on what to
|
||
include. When in doubt: add more details! By reducing ambiguity and providing
|
||
more information, it decreases back and forth and saves everyone time.
|
||
|
||
## Code changes
|
||
|
||
Want to contribute a patch? Very happy to hear that!
|
||
|
||
First, some high-level rules:
|
||
|
||
- A short proposal with some POC code is better than a lengthy piece of text
|
||
with no code. Code speaks louder than words. That being said, bigger changes
|
||
should probably start with a [discussion][discussions].
|
||
- No backward-incompatible patch will be accepted unless discussed. Sometimes
|
||
it's hard, but we try not to break people's programs unless we absolutely have
|
||
to.
|
||
- If you are writing a new feature or extending an existing one, make sure to
|
||
write some documentation.
|
||
- Bug fixes need to be accompanied with regression tests.
|
||
- New code needs to be tested.
|
||
- Your commit messages need to explain why the change is needed, even if already
|
||
included in the PR description.
|
||
|
||
It does sound like a lot, but those best practices are here to save time overall
|
||
and continuously improve the quality of the project, which is something everyone
|
||
benefits from.
|
||
|
||
### Get started
|
||
|
||
The fairly standard code contribution process looks like that:
|
||
|
||
1. [Fork the project][fork].
|
||
2. Make your changes, commit on any branch you like.
|
||
3. [Open up a pull request][pull-request]
|
||
4. Review, potential ask for changes.
|
||
5. Merge.
|
||
|
||
Feel free to ask for help! You can create draft pull requests to gather
|
||
some early feedback!
|
||
|
||
### Run the tests
|
||
|
||
You can run tests for go-toml using Go's test tool: `go test -race ./...`.
|
||
|
||
During the pull request process, all tests will be ran on Linux, Windows, and
|
||
MacOS on the last two versions of Go.
|
||
|
||
However, given GitHub's new policy to _not_ run Actions on pull requests until a
|
||
maintainer clicks on button, it is highly recommended that you run them locally
|
||
as you make changes.
|
||
|
||
### Check coverage
|
||
|
||
We use `go tool cover` to compute test coverage. Most code editors have a way to
|
||
run and display code coverage, but at the end of the day, we do this:
|
||
|
||
```
|
||
go test -covermode=atomic -coverprofile=coverage.out
|
||
go tool cover -func=coverage.out
|
||
```
|
||
|
||
and verify that the overall percentage of tested code does not go down. This is
|
||
a requirement. As a rule of thumb, all lines of code touched by your changes
|
||
should be covered. On Unix you can use `./ci.sh coverage -d v2` to check if your
|
||
code lowers the coverage.
|
||
|
||
### Verify performance
|
||
|
||
Go-toml aims to stay efficient. We rely on a set of scenarios executed with Go's
|
||
builtin benchmark systems. Because of their noisy nature, containers provided by
|
||
Github Actions cannot be reliably used for benchmarking. As a result, you are
|
||
responsible for checking that your changes do not incur a performance penalty.
|
||
You can run their following to execute benchmarks:
|
||
|
||
```
|
||
go test ./... -bench=. -count=10
|
||
```
|
||
|
||
Benchmark results should be compared against each other with
|
||
[benchstat][benchstat]. Typical flow looks like this:
|
||
|
||
1. On the `v2` branch, run `go test ./... -bench=. -count 10` and save output to
|
||
a file (for example `old.txt`).
|
||
2. Make some code changes.
|
||
3. Run `go test ....` again, and save the output to an other file (for example
|
||
`new.txt`).
|
||
4. Run `benchstat old.txt new.txt` to check that time/op does not go up in any
|
||
test.
|
||
|
||
On Unix you can use `./ci.sh benchmark -d v2` to verify how your code impacts
|
||
performance.
|
||
|
||
It is highly encouraged to add the benchstat results to your pull request
|
||
description. Pull requests that lower performance will receive more scrutiny.
|
||
|
||
[benchstat]: https://pkg.go.dev/golang.org/x/perf/cmd/benchstat
|
||
|
||
### Style
|
||
|
||
Try to look around and follow the same format and structure as the rest of the
|
||
code. We enforce using `go fmt` on the whole code base.

||
|
||
## Maintainers-only
|
||
|
||
### Merge pull request
|
||
|
||
Checklist:
|
||
|
||
- Passing CI.
|
||
- Does not introduce backward-incompatible changes (unless discussed).
|
||
- Has relevant doc changes.
|
||
- Benchstat does not show performance regression.
|
||
- Pull request is [labeled appropriately][pr-labels].
|
||
- Title will be understandable in the changelog.
|
||
|
||
1. Merge using "squash and merge".
|
||
2. Make sure to edit the commit message to keep all the useful information
|
||
nice and clean.
|
||
3. Make sure the commit title is clear and contains the PR number (#123).
|
||
|
||
### New release
|
||
|
||
1. Decide on the next version number. Use semver.
|
||
2. Generate release notes using [`gh`][gh]. Example:
|
||
```
|
||
$ gh api -X POST \
|
||
-F tag_name='v2.0.0-beta.5' \
|
||
-F target_commitish='v2' \
|
||
-F previous_tag_name='v2.0.0-beta.4' \
|
||
--jq '.body' \
|
||
repos/pelletier/go-toml/releases/generate-notes
|
||
```
|
||
3. Look for "Other changes". That would indicate a pull request not labeled
|
||
properly. Tweak labels and pull request titles until changelog looks good for
|
||
users.
|
||
4. [Draft new release][new-release].
|
||
5. Fill tag and target with the same value used to generate the changelog.
|
||
6. Set title to the new tag value.
|
||
7. Paste the generated changelog.
|
||
8. Check "create discussion", in the "Releases" category.
|
||
9. Check pre-release if new version is an alpha or beta.
