# [WIP] Enso CI Build Scripts
|
|
|
|
The code under this directory is under ongoing intensive development. As such it
|
|
has not been reviewed or cleaned up yet.
|
|
|
|
## General principles
|
|
|
|
- Written in Rust.
|
|
- Portable. Works on any platform that Enso targets.
|
|
- Do not duplicate functionality that is already available in tools being part
|
|
of our tech stack.
|
|
- Supports both developers and CI use-cases (and environments). Developers can
|
|
call it locally to do anything that CI does.
|
|
- Does not require much setup work. Where feasible sets things up for the user.
|
|
|
|
### Concepts
|
|
|
|
#### Target
|
|
|
|
- Can be built locally from sources. Building yields artifacts.
|
|
- Artifacts are self-contained to a single filesystem directory.
|
|
- Artifacts can be downloaded from a remote location rather than built with the
|
|
same effect.
|
|
- Can contain other targets.
|
|
- Artifacts can be platform-specific.
|
|
- Artifacts must be releasable as CI run artifacts or release assets.
|
|
|
|
# Usage
|
|
|
|
While the script is invoked using `cargo run`, the convenience `run` script is
|
|
provided in the repository root.
|
|
|
|
The general usage form is:
|
|
|
|
```
|
|
./run <command> [options]
|
|
```
|
|
|
|
The command itself is usually a combination of target name and subcommand, like
|
|
`ide build` or `backend test`.
|
|
|
|
At every layer, the `--help` command can be used to get more information. Note
|
|
that the information depends on the command, so running `./run --help` will not
|
|
give you the same information as `./run ide --help` nor
|
|
`./run ide build --help`.
|
|
|
|
## Targets
|
|
|
|
### IDE
|
|
|
|
IDE is the top level target for our project. It consists of `GUI` and `Backend`
|
|
targets.
|
|
|
|
Sources consist mostly of TS code for the Electron client and packaging.
|
|
|
|
Artifacts are platform specific and consist of the single image file.
|
|
|
|
### GUI
|
|
|
|
GUI is the front-end part of the project. It consists of `WASM` target.
|
|
|
|
Sources consist mostly of TS code for the web page that embeds the `WASM`
|
|
binaries.
|
|
|
|
Artifacts are portable across the platforms and consist of the web page that can
|
|
be served either using Electron client (as IDE does) or using a web server (like
|
|
the Cloud version of Enso).
|
|
|
|
### WASM
|
|
|
|
This is the core of GUI, written in Rust. It has no external dependencies.
|
|
|
|
Artifacts are portable across the platforms and consist of the single WASM
|
|
binary accompanied by the JS snippets and glue.
|
|
|
|
### Backend
|
|
|
|
Backend is the back-end part of the project, as seen from the IDE perspective.
|
|
It contains a Project Manager bundle that includes:
|
|
|
|
- Project Manager native image;
|
|
- Enso Engine distribution (with the Standard Library);
|
|
- GraalVM distribution.
|
|
|
|
These components are not represented as "Targets" (in terms of build script) but
|
|
could be and likely will be in the future.
