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 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

Pull Requests

All Git commits are required to be signed to be marked as "Verified": signed with a GPG, SSH, or S/MIME that is successfully verified by GitHub. For changing a single commit after creating the PR, use git commit -S --amend and force push the branch.
All tests must be green before merge.
Hurl git history is linear, so we ask to rebase your PR before final merge.

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 ?

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 improve. Don't hesitate to clarify, fix typos etc...
Report bugs: if possible some simple repro steps with the Hurl version, name of the platform etc...

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:

$ cargo build
   Compiling hurl_core v2.0.0-SNAPSHOT (/Users/jc/Documents/Dev/hurl/packages/hurl_core)
   ...
   Compiling hurlfmt v2.0.0-SNAPSHOT (/Users/jc/Documents/Dev/hurl/packages/hurlfmt)
   Compiling hurl v2.0.0-SNAPSHOT (/Users/jc/Documents/Dev/hurl/packages/hurl)
    Finished dev [unoptimized + debuginfo] target(s) in 2.53s

Hurl unit and integration tests need Python 3.6+ to be run. You can use a virtual environment and install the dependencies needed by the tests suite:

$ python3 -m venv .venv
$ source .venv/bin/activate
$ pip3 install --requirement bin/requirements-frozen.txt

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

$ cd integration
$ python3 server.py >server.log 2>&1 &
$ python3 ssl/server.py >server-ssl.log 2>&1 &
$ mitmdump --listen-host 127.0.0.1 --listen-port 8888 --modify-header "/From-Proxy/Hello" >mitmdump.log 2>&1 &
$ jobs
[1]    running    python3 server.py > server.log 2>&1
[2]  - running    python3 ssl/server.py > server-ssl.log 2>&1
[3]  + running    mitmdump --listen-host 127.0.0.1 --listen-port 8888 --modify-header  >  2>&1

You can check bin/test/test_prerequisites.sh and bin/test/test_prerequisites.ps1 for more details.

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

Build cargo build
Run Clippy cargo clippy
Format cargo fmt
Run units tests cargo test
Run integration tests cd integration && python3 integration.py

Et voilà 🎉!
