Eric Githinji 5fc5893fbf Support setting language and output directory in cargo xtask (#2776)
In addition to simplifying building locally (no need to set an
environment variable), this makes it possible to use the `cargo xtask
build` command in the CI and specify any output location, rather than
relying on the build.sh script.

This repository has the source code for Comprehensive Rust 🦀, a multi-day Rust
course developed by the Android team. The course covers all aspects of Rust,
from basic syntax to generics and error handling. It also includes deep dives on
[Android], [Chromium], [bare-metal], and [concurrency].
[Android]: https://google.github.io/comprehensive-rust/android.html
[Chromium]: https://google.github.io/comprehensive-rust/chromium.html
[bare-metal]: https://google.github.io/comprehensive-rust/bare-metal.html
[concurrency]: https://google.github.io/comprehensive-rust/concurrency.html
Read the course at **https://google.github.io/comprehensive-rust/**.
## Course Format and Target Audience
The course is used internally at Google when teaching Rust to experienced
software engineers. They typically have a background in C++ or Java.
The course is taught in a classroom setting and we hope it will be useful for
others who want to teach Rust to their team. The course will be less useful for
self-study since you miss out on the discussions happening in the classroom. You
don't see the questions and answers and you don't see the compiler errors we
trigger when going through the code samples. We hope to improve on this via
[speaker notes](https://github.com/google/comprehensive-rust/issues/53) and by
[publishing videos](https://github.com/google/comprehensive-rust/issues/52).

## Setup
The course is built using a few tools:
- [mdbook](https://github.com/rust-lang/mdBook)
- [mdbook-svgbob](https://github.com/boozook/mdbook-svgbob)
- [mdbook-i18n-helpers and i18n-report](https://github.com/google/mdbook-i18n-helpers)
- [mdbook-exerciser](mdbook-exerciser/)
- [mdbook-course](mdbook-course/)
- [mdbook-linkcheck2](https://github.com/marxin/mdbook-linkcheck2)
First install Rust by following the instructions on https://rustup.rs/. Then
clone this repository:
```shell
git clone https://github.com/google/comprehensive-rust/
cd comprehensive-rust
```
Then install these tools with:
```shell
cargo xtask install-tools
```
## Commands
Here is a summary of the various commands you can run in the project.
| Command | Description |
| --------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `cargo install-tools` | Install all the tools the project depends on. |
| `cargo serve` | Start a web server with the course. You'll find the content on http://localhost:3000. To serve any of the translated versions of the course, add the language flag (`--language` or `-l`) followed by xx, where xx is the ISO 639 language code (e.g. `cargo xtask serve -l da` for the Danish translation). |
| `cargo rust-tests` | Test the included Rust snippets. |
| `cargo web-tests` | Run the web driver tests in the tests directory. |
| `cargo build-book` | Create a static version of the course in the `book/` directory. Note that you have to separately build and zip exercises and add them to book/html. To build any of the translated versions of the course, add the language flag (`--language` or `-l`) followed by xx, where xx is the ISO 639 language code (e.g. `cargo xtask build -l da` for the Danish translation). [TRANSLATIONS.md](TRANSLATIONS.md) contains further instructions. |
> **Note** On Windows, you need to enable symlinks
> (`git config --global core.symlinks true`) and Developer Mode.
> **Note** Previous versions this README recommended that you use
> `cargo xtool <tool>`, i.e. `cargo xtool install-tools`. This causes issues
> with pre-existing installations of `cargo-xtool` and is now deprecated.
>
> The new syntax is almost a 1:1 mapping, although `cargo xtool build` has
> become `cargo build-book` to avoid conflicting with the built-in Cargo
> subcommand.
>
> - `cargo xtool build` -> `cargo build-book`
> - `cargo xtool install-tools` -> `cargo install-tools`
> - `cargo xtool serve` -> `cargo serve`
> - `cargo xtool run-tests` -> `cargo run-tests`
> - `cargo xtool web-tests` -> `cargo web-tests`
