cql2

Python library and command-line interface (CLI) for parsing and converting Common Query Language (CQL2), with Rust under the hood.

Usage

pip install cql2

Then:

expr = Expr("landsat:scene_id = 'LC82030282019133LGN00'")
# or
expr = cql2.parse_file("fixtures/text/example01.txt")

s = expr.to_text()
d = expr.to_json()
sql = expr.to_sql()
print("SQL query:", sql.query)
print("SQL params:", sql.params)

Or from via the command-line interface:

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