semantic-parse

This package provides a command line tool that will output ASTs in supported formats.

CLI

To output ASTs, run the semantic-parse command, specifying two mandatory options: 1) the format you'd like to return (ex., Show, JSON, etc.) and 2) the option specifying whether the source code will be passed in directly via command line (using --sourceString) or via providing the file path --sourceFile.

Filepath:

semantic-parse --format [FORMAT] --sourceFile [FILEPATH]

Source string:

semantic-parse --format [FORMAT] --sourceString [SOURCE]

An example command is:

semantic-parse -- --format Show --sourceString "a"

This will generate an AST
