cql2-rs

cql-rs is command-line interface (CLI), Python package, and Rust crate for parsing, validating, and converting Common Query Language (CQL2).

CLI

To install the CLI, you'll need Rust. Then:

$ cargo install cql2-cli
$ cql2 -o json "landsat:scene_id = 'LC82030282019133LGN00'"
{"op":"=","args":[{"property":"landsat:scene_id"},"LC82030282019133LGN00"]}

Python

Install with pip:

pip install cql2

Then:

from cql2 import Expr
expr = Expr("landsat:scene_id = 'LC82030282019133LGN00'")
d = expr.to_json()

See the API documentation for more.

Rust

Add cql2 to your dependencies:

cargo add cql2

Then:

use cql2::Expr;

let expr: Expr = "landsat:scene_id = 'LC82030282019133LGN00'".parse().unwrap();
assert!(expr.is_valid());
let json = expr.to_json().unwrap();
