verbal_expressions

Example 3: Verbal expressions

Pseudo AST

Generated from original.py using pseudo-python

That's a simple library similar to VerbalExpressions

It defines a DSL for more readable definition of regular expressions and uses it with the example from VerbalExpressions README

It demonstrates

• suitability for writing/porting little libraries and DSL-s

• native standard library use: Pseudo uses the target language standard library string/regex methods/functions

• oop handling: It uses prototypical oop in the js version and class-based code in the other versions

• string interpolation: pseudo-python recognizes and even checks the types of c-style %d%s formatting strings and it uses an idiomatic interpolation mechanism for each of the target languages
