To support polymorphism, some methods can control Pangaea syntactic elements.
| method | usage |
|---|---|
_literalProxy |
proxies literalcall |
_incBy |
used for range indexing (e.g: (1:10:2)._iter generates next value by ._incBy(2)) |
_iter |
used to generate iterator of the receiver in list/reduce chain |
_missing |
called when no properties found on the prototype chain |
_name |
used in REPL for pretty-printing receivers (e.g: Obj._name == "Obj") |
at |
used for indexing (a[b] is a.at([b])) |
B |
used to convert condition in if expression to boolean |
call |
used for function call (f() is f.call()) |
digest |
used in a list chain argument to convert evaluated value |
S |
used in p method to convert the receiver to a string |
eval and evalEnv evaluate source codes dynamically.
eval: returns evaluated valueevalEnv: returns the environment after evaluation as an object
`a := 3; b := 2; a + b`.eval # 5
`a := 3; b := 2; a + b`.evalEnv # {"a": 3, "b": 2}
