Axon parseAst Parser

Parses the output of SkySpark's parseAst function.

Usage

1. Get the string output of SkySpark's parseAst function.
   • For example, run read(func and name == "yourFunction")->src.parseAst().toAxonCode().
2. Use this library's parse function on that string.

Why parse the output of parseAst, instead of parsing Axon itself?

1. It's substantially more involved to parse Axon, instead of parseAst's output.
   • We can parse parseAst output in under 200 lines of LALRPOP grammar.
2. Axon appears to be an ambiguous language to parse (at least LALRPOP was claiming it was ambiguous).

Unimplemented

• Exponent numbers.
  • For example, 5e10 will not parse.
  • Why? Exponent numbers are currently not supported in the raystack_core dependency.
• Hexadecimal numbers.
• Hour format [0-9]?[0-9] in time parsing.
  • For example, 09:30:00 will parse, but 9:30:00 will not.
  • Why? To simplify the LALRPOP grammar code.
• Fractional seconds in time parsing.
  • For example, 09:30:00 will parse, but 09:30:00.123 will not.
  • Why? To simplify the LALRPOP grammar code.
• Raw strings may not work, it depends how parseAst serializes them, I need to test this.
  • For example, r"abc123" in Axon may not parse.
