Add symbols from an axiom to symbolic environment.

Like add_rule but allow polymorphic rules.

Add symbols from a rule to a symbolic environment.

apply rules lstream will apply rules once to lstream.

As apply but with a complete mapping.

Replace each variables by a subtree.

Replace some variables by a subtree.

A turtle that can draw on any Cairo surface.

As check_stream for a rule.

Check a stream against an environment.

Compress the string in the optional env and return the resulting closure.

Compress a tree in the given environment, ie.

Apply Calc.compress to every arithmetic expressions.

Compress a tree using the given function, ie.

A symbol is considered a constant when it's not used in any of the main rules of a L-system.

Evaluate a tree in the given environment.

Evaluate a tree, the given function is used to evaluate variables.

Evaluate a L-system at the n-th generation.

Like eval_lsys , but will ignore post rules and uncompress the stream instead.

template size path returns a complete svg elements using the path.

Print an arithmetic expressions.

Can be feeded directly to Lilis.Engine.eval_iter_lsys.

Can be combined with Lilis.Engine.map_crules to use Lilis.Engine.eval_iter_lsys.

This turtle implements most movement calculations, without any actual drawing.

Get the sequence of variables in the given tree.
