SimplExp

Fast and crude mathematical expression simplifier for Python and Rust

Used in BoldUI.

Example

from simplexp import var, Expr, Oplist

# Simplification:
expr = ((var('x') + var('x')) / 2 + 10)
print(expr)  # => (x + 10)

# Serialization:
print(Expr.to_dict(expr))  # => {'type': 'add', 'a': {'type': 'var', 'name': 'x'}, 'b': 10}

# Serialization into operation list:
print(Oplist(var('x') + var('y')).to_list())  # => 
# [
#   {'type': 'var', 'name': 'x'},
#   {'type': 'var', 'name': 'y'},
#   {'type': 'add', 'a': 0, 'b': 1}
# ]

# Values are kept as values (when optimized successfully):
print(Expr.to_dict(Expr(100) + 200))  # => 300

How it looks visually

Optimizing a "rect" operation in BoldUI, which holds a list of 4 expressions. Each is optimized using SimplExp:
