* URL hosts, paths and query values can have variables with an optional

* Registered URLs can be built, or "reversed", which helps maintaining

# Contributing
Thanks for your interest in contributing! This document contains `nats-io/nats.go` specific contributing details. If you
are a first-time contributor, please refer to the general [NATS Contributor Guide](https://nats.io/contributing/) to get
a comprehensive overview of contributing to the NATS project.
## Getting started
There are three general ways you can contribute to this repo:
- Proposing an enhancement or new feature
- Reporting a bug or regression
- Contributing changes to the source code
For the first two, refer to the [GitHub Issues](https://github.com/nats-io/nats.go/issues/new/choose) which guides you
through the available options along with the needed information to collect.
## Contributing changes
_Prior to opening a pull request, it is recommended to open an issue first to ensure the maintainers can review intended
changes. Exceptions to this rule include fixing non-functional source such as code comments, documentation or other
supporting files._
Proposing source code changes is done through GitHub's standard pull request workflow.
If your branch is a work-in-progress then please start by creating your pull requests as draft, by clicking the
down-arrow next to the `Create pull request` button and instead selecting `Create draft pull request`.
This will defer the automatic process of requesting a review from the NATS team and significantly reduces noise until
you are ready. Once you are happy, you can click the `Ready for review` button.
### Guidelines
A good pull request includes:
- A high-level description of the changes, including links to any issues that are related by adding comments
like `Resolves #NNN` to your description.
See [Linking a Pull Request to an Issue](https://docs.github.com/en/issues/tracking-your-work-with-issues/linking-a-pull-request-to-an-issue)
for more information.
- An up-to-date parent commit. Please make sure you are pulling in the latest `main` branch and rebasing your work on
top of it, i.e. `git rebase main`.
- Unit tests where appropriate. Bug fixes will benefit from the addition of regression tests. New features will not be
accepted without suitable test coverage!
- No more commits than necessary. Sometimes having multiple commits is useful for telling a story or isolating changes
from one another, but please squash down any unnecessary commits that may just be for clean-up, comments or small
changes.
- No additional external dependencies that aren't absolutely essential. Please do everything you can to avoid pulling in
additional libraries/dependencies into `go.mod` as we will be very critical of these.
### Sign-off
In order to accept a contribution, you will first need to certify that the contribution is your original work and that
you license the work to the project under
the [Apache-2.0 license](https://github.com/nats-io/nats.go/blob/main/LICENSE).
This is done by using `Signed-off-by` statements, which should appear in **both** your commit messages and your PR
description. Please note that we can only accept sign-offs under a legal name. Nicknames and aliases are not permitted.
To perform a sign-off with `git`, use `git commit -s` (or `--signoff`).
## Get help
If you have questions about the contribution process, please start
a [GitHub discussion](https://github.com/nats-io/nats.go/discussions), join the [NATS Slack](https://slack.nats.io/), or
send your question to the [NATS Google Group](https://groups.google.com/forum/#!forum/natsio).
## Testing
You should use `go_test.mod` to manage your testing dependencies. Please use the following command to update your
dependencies and avoid changing the main `go.mod` in a PR:
```shell
go mod tidy -modfile=go_test.mod
```
To the tests you can pass `-modfile=go_test.mod` flag to `go test` or instead you can also set `GOFLAGS="-modfile=go_test.mod"` as an environment variable:
```shell
go test ./... -modfile=go_test.mod
```

## Backwards compatibility
In the development of nats.go, we are committed to maintaining backward compatibility and ensuring a stable and reliable experience for all users. In general, we follow the standard go compatibility guidelines.
However, it's important to clarify our stance on certain types of changes:
- **Expanding structures:**
Adding new fields to structs is not considered a breaking change.
- **Adding methods to exported interfaces:**
Extending public interfaces with new methods is also not viewed as a breaking change within the context of this project. It is important to note that no unexported methods will be added to interfaces allowing users to implement them.
Additionally, this library always supports at least 2 latest minor Go versions. For example, if the latest Go version is 1.22, the library will support Go 1.21 and 1.22.
