Module highlight 

Small hand-rolled highlighters for the three languages this REPL shows: the JSON going over the wire, the Rust it generates, and the command line you are typing.

Functions

command

Highlight the input line: the command, the question name, the | separators, and the label=description / yes: criteria inside them.

json

Highlight pretty-printed JSON, indented into the transcript.

json_spans

One line of JSON. Keys are told from strings by the colon that follows them.

rust

Highlight generated Rust, indented into the transcript.
