cel-eval

cel-eval is a tool that you can use to evaluate CEL expressions locally. It works by allowing you to define an HTTP request and a CEL expression that is evaluated against the request.

How to use

1. Build cel-eval by running go build in this directory.
2. Define an HTTP request

$ cat > request <<EOF
POST /foo HTTP/1.1
Content-Length: 29
Content-Type: application/json
X-Header: tacocat

{"test": {"nested": "value"}}
EOF

1. Define the CEL expression

$ cat > expression <<EOF
body.test.nested == "value"
EOF

1. Run cel-eval

$ ./cel-eval --expression ./expression --http-request ./request
true
