@bufbuild/cel-spec

This package provides CEL definitions and test data from https://github.com/google/cel-spec v0.24.0.

CEL uses Protocol Buffer definitions for parsed expressions. For example, the message cel.expr.ParsedExpr provides an abstract representation of a parsed CEL expression. The message types and schemas can be imported from @bufbuild/cel-spec:

import { ParsedExpr } from "@bufbuild/cel-spec/cel/expr/syntax_pb.js";

CEL's conformance test suite also uses Protocol Buffers to define test cases. All messages from the cel.expr.conformance namespace are exported from this package as well, and the function getSimpleTestFiles provides conformance test data:

import { getSimpleTestFiles } from "@bufbuild/cel-spec/testdata/simple.js";
import { getTestRegistry } from "@bufbuild/cel-spec/testdata/registry.js";
import type { SimpleTestFile } from "@bufbuild/cel-spec/cel/expr/conformance/test/simple_pb.js";

const files: SimpleTestFile[] = getSimpleTestFiles();

In addition to CEL's conformance test data, this package also exports parser tests extracted from github.com/google/cel-go:

import { parserTests } from "@bufbuild/cel-spec/testdata/parser.js";
import { parserTests as parserComprehensionsTests } from "@bufbuild/cel-spec/testdata/parser-comprehensions.js";
