|
* Differentiate between colors and vectors in the AST.Tavian Barnes2009-12-213-9/+102
|
* Support #declare, #local, and #undef.Tavian Barnes2009-12-214-283/+396
|
* Make symbol table semantics line up with povray's.Tavian Barnes2009-12-195-11/+75
|
* Implement a symbol table.Tavian Barnes2009-12-1911-446/+719
|
* Forgot fclose() in dmnsn_realize_string().Tavian Barnes2009-12-191-1/+5
|
* Preliminary dmnsn_realize_string(), just in case.Tavian Barnes2009-12-173-1/+21
|
* Tokenize on-the-fly.Tavian Barnes2009-12-177-181/+190
| | | | | No more manual tokenization and parsing, giving a simpler interface. Also, this brings us closer to a dmnsn_realize_string() interface.
* Accept width and height command-line arguments.Tavian Barnes2009-12-162-8/+33

* Support scaling and translation transformations.Tavian Barnes2009-11-253-3/+44
|
* Use FLOAT_EXPR in VECTOR_LITERAL rather than FLOAT.Tavian Barnes2009-11-251-4/+6
| | | | This is to future-proof lazily-evaluated vector expressions.

|
* Evaluate arithmetic expressions during parsing when possible.Tavian Barnes2009-11-201-19/+188
