# Hurl Contributing Guide

Thank you for investing time in our project!

## Issues

Whether you have discovered a bug, want a new feature in Hurl, or change code, [please fill an issue] or [start a discussion]
before any PR. We like to discuss things before implementation and want to be sure that: 

- Any new features are coherent with [Hurl core values].
- You don't waste time on a feature that will not fit Hurl.
- All options have been considered if possible.
- We try to minimize dependencies and import new crates parsimoniously.

We really want to be focused and consider any new features carefully before committing to it. A new idea can be really 
relevant to you and we understand it; that's said, we try to reflect on every aspect (maintainability, feature fitting with future evolutions etc...). Don't be too harsh on us if we postpone your proposal, it's for the sake of Hurl!

## Hurl Core Values

- Hurl is a first class citizen CLI tool, fast and reliable.
- Hurl is a cherry on the top of curl. What you can do with curl, you could do it with Hurl.
- Hurl file format is text plain, loosely based on HTTP.
- Hurl is multiplatform, working on Linux, macOS, Windows.

## How Can You Help ?

Issues opened to contributors are labelled ["open-to-contribution"](https://github.com/Orange-OpenSource/hurl/issues?q=is%3Aissue%20state%3Aopen%20label%3Aopen-to-contribution).
Apart for these issues, we're looking forward to contributors for:

- Installing / Packet managers: bundle Hurl for a particular packet manager is welcome. Currently, we built binaries for
  Linux, macOS, Windows and we support a narrow set of packet manager. [More would be better!].
- IDE Support: everything from color syntax (in VSCode, Vim, IntelliJ, TextMate etc...) would be a good idea. An
  integrated way to run Hurl file would be cool also.
- [Documentation] is a never finished work and could be always improved. Don't hesitate to clarify, even fix typos etc...
- Report bugs: if possible some simple repro steps with `hurl --version`, name of the platform etc... PR for bugs fixes are really appreciated. If there is [an integration test] that complement it, it's the cherry on the cake.

## Pull Requests

- [Create a new Git branch], don't use `master` branch for PR.
- All Git commits are [required to be signed] and marked as "Verified": signed with a GPG, SSH, or S/MIME that is successfully verified by GitHub.
- Commit messages are simple phrases, don't use [Semantic Commit Messages] nor [Conventional Commits]
  - ❌ `fix: missing space in variable option HTML export`
  - ✅ `Fix missing space in variable option HTML export`
- All tests must be green before merge. Our CI/CD will run [a test suite] to insure everything is OK.
- Hurl Git history is linear, so we may rebase your PR on your fork before final merge.

## Build and Test

Hurl is a Rust project, so you will need the Rust toolchain to build it. You can check the [Hurl build documentation] to 
see how to build locally the latest version (master branch).

Once your setup is ready, just build the project:

```shell
$ cargo build
   Compiling hurl_core v6.0.0-SNAPSHOT (/Users/jc/Documents/Dev/hurl/packages/hurl_core)
   ...
   Compiling hurlfmt v6.0.0-SNAPSHOT (/Users/jc/Documents/Dev/hurl/packages/hurlfmt)
   Compiling hurl v6.0.0-SNAPSHOT (/Users/jc/Documents/Dev/hurl/packages/hurl)
    Finished dev [unoptimized + debuginfo] target(s) in 2.53s
```

To run unit tests, you can run:

```shell
$ cargo test --lib
```


Hurl has a big suite of [integration tests]. To run the integration tests, you'll need Python 3.9+. You can use a [virtual environment] and install the dependencies needed
by the tests suite:

```shell
$ python3 -m venv .venv
$ source .venv/bin/activate
$ pip install --requirement bin/requirements-frozen.txt 
```

Then, you can launch our local server (used to test Hurl features):

```shell
$ cd integration/hurl
$ python3 server.py > server.log 2>&1 &
$ python3 tests_ssl/ssl_server.py 8001 tests_ssl/certs/server/cert.selfsigned.pem false > server-ssl-selfsigned.log 2>&1 &
$ python3 tests_ssl/ssl_server.py 8002 tests_ssl/certs/server/cert.pem false > server-ssl-signedbyca.log 2>&1 &
$ python3 tests_ssl/ssl_server.py 8003 tests_ssl/certs/server/cert.selfsigned.pem true > server-ssl-client-authent.log 2>&1 &
$ python3 tests_unix_socket/unix_socket_server.py > server-unix-socket.log 2>&1 &
$ squid_conf="cache deny all\ncache_log /dev/null\naccess_log /dev/null\nhttp_access allow all\nhttp_port 127.0.0.1:3128\nrequest_header_add From-Proxy Hello\nreply_header_add From-Proxy Hello"
$ (echo -e "${squid_conf}" | sudo squid -d 2 -N -f /dev/stdin | sudo tee proxy.log 2>&1) &
$ jobs

```

You can check [the integration `README`] for more details

Now, you can follow these steps when you make changes:

1. Build `cargo build`
2. Run Clippy `cargo clippy`
3. Format `cargo fmt`
4. Run units tests `cargo test --lib`
5. Run integration tests `cd integration/hurl && python3 integration.py`

Et voilà 🎉!
