As always, a massive diff which is largely just moving files between projects. This does fix a couple of issues with advancements, but otherwise should behave the same. Speaking of which, should probably go and test some of these recipes...

# Contributing to CC: Tweaked
|
|
As with many open source projects, CC: Tweaked thrives on contributions from other people! This document (hopefully)
|
|
provides an introduction as to how to get started in helping out.
|
|
|
|
If you've any other questions, [just ask the community][community] or [open an issue][new-issue].
|
|
|
|
## Reporting issues
|
|
If you have a bug, suggestion, or other feedback, the best thing to do is [file an issue][new-issue]. When doing so,
|
|
do use the issue templates - they provide a useful hint on what information to provide.
|
|
|
|
## Translations
|
|
Translations are managed through [Weblate], an online interface for managing language strings. This is synced
|
|
automatically with GitHub, so please don't submit PRs adding/changing translations!
|
|
|
|
## Developing
|
|
In order to develop CC: Tweaked, you'll need to download the source code and then run it. This is a pretty simple
|
|
process. When building on Windows, Use `gradlew.bat` instead of `./gradlew`.
|
|
|
|
- **Clone the repository:** `git clone https://github.com/SquidDev-CC/CC-Tweaked.git && cd CC-Tweaked`
|
|
- **Setup Forge:** `./gradlew build`
|
|
- **Run Minecraft:** `./gradlew runClient` (or run the `GradleStart` class from your IDE).
|
|
- **Optionally:** For small PRs (especially those only touching Lua code), it may be easier to use GitPod, which
|
|
provides a pre-configured environment: [](https://gitpod.io/#https://github.com/SquidDev-CC/CC-Tweaked/)
|
|
|
|
Do note you will need to download the mod after compiling to test.
|
|
|
|
If you want to run CC:T in a normal Minecraft instance, run `./gradlew build` and copy the `.jar` from `build/libs`.
|
|
These commands may take a few minutes to run the first time, as the environment is set up, but should be much faster
|
|
afterwards.
|
|
|
|
The following sections describe the more niche sections of CC: Tweaked's build system. Some bits of these are
|
|
quite-complex, and (dare I say) over-engineered, so you may wish to ignore them. Well tested/documented PRs are always
|
|
preferred (and I'd definitely recommend setting up the tooling if you're doing serious development work), but for
|
|
small changes it can be a lot.
|
|
|
|
### Code linters
|
|
CC: Tweaked uses a couple of "linters" on its source code, to enforce a consistent style across the project. While these
|
|
are run whenever you submit a PR, it's often useful to run this before committing.
|
|
|
|
- **[Checkstyle]:** Checks Java code to ensure it is consistently formatted. This can be run with `./gradlew build` or
|
|
`./gradle check`.
|
|
- **[illuaminate]:** Checks Lua code for semantic and styleistic issues. See [the usage section][illuaminate-usage] for
|
|
how to download and run it. You may need to generate the Java documentation stubs (see "Documentation" below) for all
|
|
lints to pass.
|
|
|
|
### Documentation
|
|
When writing documentation for [CC: Tweaked's documentation website][docs], it may be useful to build the documentation
|
|
and preview it yourself before submitting a PR.
|
|
|
|
Building all documentation is, sadly, a multi-stage process (though this is largely hidden by Gradle). First we need to
|
|
convert Java doc-comments into Lua ones, we also generate some Javascript to embed. All of this is then finally fed into
|
|
illuaminate, which spits out our HTML.
|
|
|
|
#### Setting up the tooling
|
|
For various reasons, getting the environment set up to build documentation can be pretty complex. I'd quite like to
|
|
automate this via Docker and/or nix in the future, but this needs to be done manually for now.
|
|
|
|
This tooling is only needed if you need to build the whole website. If you just want to generate the Lua stubs, you can
|
|
skp this section.
|
|
- Install Node/npm and install our Node packages with `npm ci`.
|
|
- Install [illuaminate][illuaminate-usage] as described above.
|
|
|
|
#### Building documentation
|
|
Gradle should be your entrypoint to building most documentation. There's two tasks which are of interest:
|
|
|
|
- `./gradlew luaJavadoc` - Generate documentation stubs for Java methods.
|
|
- `./gradlew docWebsite` - Generate the whole website (including Javascript pages). The resulting HTML is stored at
|
|
`./build/docs/lua/`.
|
|
|
|
#### Writing documentation
|
|
illuaminate's documentation system is not currently documented (somewhat ironic), but is _largely_ the same as
|
|
[ldoc][ldoc]. Documentation comments are written in Markdown,
|
|
|
|
Our markdown engine does _not_ support GitHub flavoured markdown, and so does not support all the features one might
|
|
expect (such as tables). It is very much recommended that you build and preview the docs locally first.
|
|
|
|
### Testing
|
|
Thankfully running tests is much simpler than running the documentation generator! `./gradlew check` will run the
|
|
entire test suite (and some additional bits of verification).
|
|
|
|
Before we get into writing tests, it's worth mentioning the various test suites that CC: Tweaked has:
|
|
- "Core" Java (`./src/test/java`): These test core bits of the mod which don't require any Minecraft interaction.
|
|
This includes the `@LuaFunction` system, file system code, etc...
|
|
|
|
These tests are run by `./gradlew test`.
|
|
|
|
- CraftOS (`./src/test/resources/test-rom/`): These tests are written in Lua, and ensure the Lua environment, libraries
|
|
and programs work as expected. These are (generally) written to be able to be run on emulators too, to provide some
|
|
sort of compliance test.
|
|
|
|
These tests are run by the '"Core" Java' test suite, and so are also run with `./gradlew test`.
|
|
|
|
- In-game (`./src/testMod/java/dan200/computercraft/ingame/`): These tests are run on an actual Minecraft server and client,
|
|
using [the same system Mojang do][mc-test]. The aim of these is to test in-game behaviour of blocks and peripherals.
|
|
|
|
These are run by `./gradlew testClient` and `./gradlew testServer`. You may want to run the client under `xvfb-run`
|
|
or similar when running in a headless environment.
|
|
|
|
## CraftOS tests
|
|
CraftOS's tests are written using a test system called "mcfly", heavily inspired by [busted] (and thus RSpec). Groups of
|
|
tests go inside `describe` blocks, and a single test goes inside `it`.
|
|
|
|
Assertions are generally written using `expect` (inspired by Hamcrest and the like). For instance, `expect(foo):eq("bar")`
|
|
asserts that your variable `foo` is equal to the expected value `"bar"`.
