# Decodal
|
|
|
|
Decodal is a small deterministic DSL for describing, composing, validating, and materializing structured data.
|
|
|
|
It is designed around a lightweight Rust library:
|
|
|
|
- host-supplied imports through `SourceLoader`
|
|
- no filesystem access in the library core
|
|
- concrete and abstract values with constraints and defaults
|
|
- deterministic expression evaluation
|
|
- optional regex support behind a Cargo feature
|
|
- browser playground support through WebAssembly
|
|
|
|
## Library crate
|
|
|
|
Embedded hosts should depend on `decodal` and provide imports with a `SourceLoader`.
|
|
|
|
```toml
|
|
[dependencies]
|
|
decodal = "0.1"
|
|
```
|
|
|
|
## CLI
|
|
|
|
A standalone CLI is kept in this repository as the `decodal-cli` workspace package.
|
|
It builds a `decodal` binary, but it is not the primary crates.io package.
|
|
|
|
Run a Decodal file from the repository:
|
|
|
|
```sh
|
|
cargo run -q -p decodal-cli -- examples/advanced/main.dcdl
|
|
```
|
|
|
|
Enable optional regex support when needed:
|
|
|
|
```sh
|
|
cargo run -q -p decodal-cli --features regex -- examples/regex/main.dcdl
|
|
```
|
|
|
|
## Web playground
|
|
|
|
The static documentation site and browser playground live under:
|
|
|
|
```text
|
|
site/decodal-site/
|
|
```
