glasslang's Issues

Allow type constructors, override PrimitiveType call method

e.g. num(23), str('test')

Add dictionaries!

Add dictionaries, defined by $keyAndValue = { "key" = 0, 0 = "value" }. To get value, do keyAndValue(keyToGetValFrom)

New operators

Add operators such as +=, -=, /=, *=, and also ++, --.

Change symbols to keywords

Change $ to var, @ to func, & to import

Define builtin behavior from within its primitive class

All variables get passed to children context, even when not through variables

Need to make sure the only variables that get passed from a context to a function are the arguments along with the global variables. NOTE: UNTESTED (80% sure this is true)

Mutable operations

Some* of the primitives can be changed to mutable operations. May keep it unmutable to keep consistency, and if so, this will be closed and marked as wontfix.

= operator on already defined variables and allow empty initialization

Once you define a variable such as $var = 4, you have to enter an initial value, and every time you want to change it you have to redeclare it with $. To counteract this, override the (base?) primitive class override the equals method, (currently is none, add it to the BinOp parse method) to update the left value to the value on the right. Maybe add $var with having optional initialization, however I can see some syntax issues with this.

Parameters failed to be passed to functions called within functions

Reproduce:

@def(otherFunc, a) => otherFunc(a)
@test(a) => a
def(test, 1)

Allow parentheses in for loops

Currently, you can use parentheses with if and while statements, but not with for loops. This should be fixed to increase consistancy.

Enhance call methods for string & list

Currently, each method creates a new instance, duplicating code. Maybe drop it down to Primitive class level, something very similar to PrimitiveBaseFunction?

Infinite recursion causes java to throw StackOverflow, Glass should catch it instead

Reproduce:

@test(a) => a(a)
@a(a) => a(a)
a(test)

Records

Maybe add records as a struct object? to declare, maybe %recordName(arg...) and to get values, recordName(nameOfArgToGet)
