### Install the prerequisites
|
||||
|
||||
1. Install [`rustup`](https://rust-lang.github.io/rustup/): the officially recommended Rust toolchain manager
|
||||
- It's available on Ubuntu as a [Snap](https://snapcraft.io/rustup)
|
||||
* It's available on Ubuntu as a [Snap](https://snapcraft.io/rustup)
|
||||
2. Call `rustup default stable` to "download the latest stable release of Rust and set it as your default toolchain"
|
||||
- If you forget, the `rustup` [help system](https://github.com/rust-lang/rustup/blob/d9b3601c3feb2e88cf3f8ca4f7ab4fdad71441fd/src/errors.rs#L109-L112) will remind you

|
||||
3. Call `rustup target add wasm32-unknown-unknown` to add the [most generic 32-bit WebAssembly target](https://doc.rust-lang.org/nightly/rustc/platform-support/wasm32-unknown-unknown.html)
|
||||
4. Call `cargo install wasm-pack` to install the [WebAssembly toolchain](https://rustwasm.github.io/docs/wasm-pack/)
|
||||
5. Call `cargo install trunk` to install the [Trunk](https://trunkrs.dev/) web-build tool
|
||||
6. Add the `.cargo/bin` folder in your home directory to your executable search path
|
||||
- This lets you call Trunk, and other tools installed by Cargo, without specifying their paths
|
||||
- On POSIX systems, the search path is stored in the `PATH` environment variable

|
||||
|
||||
### Play with the prototype
|
||||
|
||||
1. From the `app-proto` folder, call `trunk serve --release` to build and serve the prototype
|
||||
- The crates the prototype depends on will be downloaded and served automatically
|
||||
- For a faster build, at the expense of a much slower prototype, you can call `trunk serve` without the `--release` flag
|
||||
- If you want to stay in the top-level folder, you can call `trunk serve --config app-proto [--release]` from there instead.

|
||||
* *If you want to stay in the top-level folder, you can call `trunk serve --config app-proto [--release]`* from there instead.
|
||||
3. In a web browser, visit one of the URLs listed under the message `INFO 📡 server listening at:`
|
||||
- Touching any file in the `app-proto` folder will make Trunk rebuild and live-reload the prototype
|
||||
* *Touching any file in the `app-proto` folder will make Trunk rebuild and live-reload the prototype*
|
||||
4. Press *ctrl+C* in the shell where Trunk is running to stop serving the prototype
|
||||
|
||||
### Run the engine on some example problems
|
||||
|
||||
1. Use `sh` to run the script `tools/run-examples.sh`
|
||||
- The script is location-independent, so you can do this from anywhere in the dyna3 repository
|
||||
- The call from the top level of the repository is:
|
||||
|
||||
```bash
|
||||
sh tools/run-examples.sh
|
||||
```
|
||||
- For each example problem, the engine will print the value of the loss function at each optimization step
|
||||
- The first example that prints is the same as the Irisawa hexlet example from the Julia version of the engine prototype. If you go into `engine-proto/gram-test`, launch Julia, and then
|
||||
1. Go into the `app-proto` folder
|
||||
2. Call `./run-examples`

||||
### Run the automated tests
|
||||
|
||||
1. Go into the `app-proto` folder
|
||||
2. Call `cargo test`
|
||||
|
||||
### Deploy the prototype
|
||||
|
||||
1. From the `app-proto` folder, call `trunk build --release`
|
||||
- Building in [release mode](https://doc.rust-lang.org/cargo/reference/profiles.html#release) produces an executable which is smaller and often much faster, but harder to debug and more time-consuming to build
|
||||
- If you want to stay in the top-level folder, you can call `trunk build --config app-proto --release` from there instead
|
||||
2. Use `sh` to run the packaging script `tools/package-for-deployment.sh`.
|
||||
- The script is location-independent, so you can do this from anywhere in the dyna3 repository
|
||||
- The call from the top level of the repository is:
|
||||
```bash
|
||||
sh tools/package-for-deployment.sh
|
||||
```
|
||||
- This will overwrite or replace the files in `deploy/dyna3`
|
||||
3. Put the contents of `deploy/dyna3` in the folder on your server that the prototype will be served from.
|
||||
- To simplify uploading, you might want to combine these files into an archive called `deploy/dyna3.zip`. Git has been set to ignore this path
