json_ast 1.0.5

json_ast #

Build Status

A forgettable port of this javascript library. It is not elegant, it doesn't bring any pride to humanity.

Builds the AST (Abstract Syntax Tree) of a JSON string.

The good #

  • It works.
  • It is battle tested.
  • It could be worse (like not having anything at all).

The bad #

This library is a port from an existing javascript library. I wanted it to work but I wasn't aiming for perfection, that means:

  • Types are flimsy
  • Algorithms are not a jewel of modern programming.
  • I ported this library to use only one feature.

The ugly #

  • I would re-write the whole thing if I had any serious interest in this.
