"PARSE LEXED-AST &optional DYNAMIC-PRIMS => AST
DYNAMIC-PRIMS: DYNAMIC-PRIM*
+ DYNAMIC-PRIM: (:name NAME :args ARGS :infix INFIX)
+ ARGS: ARG*
ARGUMENTS AND VALUES:
LEXED-AST: An ambigious ast
AST: An unambigious ast that can be transpiled
- DYNAMIC-PRIM: A prim not statically defined
+ NAME: A symbol in the keyword package
+ INFIX: Boolean denoting whether the prim is infix
+ ARG: A list of symbols denoting the type of argument
DESCRIPTION:
things not statically defined by the NetLogo language, be they user defined
procedures or generated primitives from breed declarations.
+ The possible values for ARG are :agentset, :boolean, :number, :command-block,
+ or t for wildcard.
+
The need for a parser between the lexer and the transpiler is because NetLogo
needs two passes to turn into something that can be used. This is the only entry
point into this module, and should probably remain that way.
