## 📚 Getting Started
The `wdl` family of crates consists of (a) a number of component crates (any
crate that is not explicitly `wdl`) that are developed and versioned
independently, and (b) a convenience crate (the `wdl` crate) that exists to ease
syncing compatible component crates versions. Component crates can be enabled
using features and are generally re-exported crates without the `wdl-` (or
`wdl_`) prefix.
This repository contains crates that can be used to work with WDL within your
own Rust projects—if you're looking for a command-line tool built on top of
these crates instead, you should check out [`sprocket`].
### Convenience Crate
Most users should prefer selecting a version of the convenience crate and
enabling features as they wish. For example,
```bash
cargo add wdl --features grammar
```
and then
```rust
use wdl::grammar;
```
### Component Crate(s)
You are free to include component crates directly. For example,
```bash
cargo add wdl_grammar
```
and then
```rust
use wdl_grammar;
```
Be aware, however, that versions between component crates are explicitly not
compatible. In other words, if you choose not to use the convenience crate, it
is not simple to derive which crate versions are compatible, and you'll need to
manually sync those. We _highly_ recommend using the convenience crate if you
intend to use more than one component crate in conjunction.
### Minimum Supported Rust Version
The minimum supported Rust version is currently `1.80.0`.
There is a CI job that verifies the declared minimum supported version.
If a contributor submits a PR that uses a feature from a newer version of Rust,
the contributor is responsible for updating the minimum supported version in
the `Cargo.toml`.
Contributors may update the minimum supported version as-needed to the latest
stable release of Rust.
To facilitate the discovery of what the minimum supported version should be,
install the `cargo-msrv` tool:
```bash
cargo install cargo-msrv
```
And run the following command:
```bash
cargo msrv --min 1.80.0
```
If the reported version is newer than the crate's current minimum supported
version, an update is required.
## ✨ The `wdl` CLI tool
The `wdl` CLI tool provides commands to assist in the development of
the `wdl` family of crates.
The `wdl` CLI tool can be run with the following command:
```bash
cargo run --bin wdl --features cli -- $ARGS
```
Where `$ARGS` are the command line arguments to the `wdl` CLI tool.
The `wdl` CLI tool currently supports the following subcommands:
* `parse` - Parses a WDL document and prints both the parse diagnostics and the
resulting Concrete Syntax Tree (CST).
* `check` - Parses, validates, and analyzes a WDL document or a directory
containing WDL documents. Exits with a status code of `0` if the documents
are valid; otherwise, prints the validation diagnostics and exits with a
status code of `1`.
* `lint` - Parses, validates, and runs the linting rules on a WDL document.
Exits with a status code of `0` if the file passes all lints; otherwise,
prints the linting diagnostics and exits with a status code of `1`.
* `analyze` - Parses, validates, and analyzes a single WDL document or a
directory containing WDL documents. Prints a debug representation of the
analysis result and exits with a status code of `0` if the documents are
valid; otherwise, prints the validation diagnostics and exits with a status
code of `1`.
* `format` - Parses, validates, and then formats a single WDL document, printing
the result to STDOUT.
Each of the subcommands supports passing `-` as the file path to denote reading
from STDIN instead of a file on disk.
## 🖥️ Development
To bootstrap a development environment, please use the following commands.
```bash
# Clone the repository
git clone git@github.com:stjude-rust-labs/wdl.git
cd wdl
# Build the crate in release mode
cargo build --release
# List out the examples
cargo run --release --example
```
## 🚧️ Tests
Before submitting any pull requests, please make sure the code passes the
following checks (from the root directory).
```bash
# Run the project's tests.
cargo test --all-features
# Run the tests for the examples.
cargo test --examples --all-features
# Ensure the project doesn't have any linting warnings.
cargo clippy --all-features
# Ensure the project passes `cargo fmt`.
# Currently this requires nightly Rust
cargo +nightly fmt --check
# Ensure the docs build.
cargo doc
