A minimal implementation of Orelang in TypeScript
Orelang is simple and minimal programming language declared at the articleプログラミング言語を作る。１時間で
This is an implementation of Orelang and provides more functions
- if/cond expression
- compare functions: >,>=,<,<=
- logics : and(&&), or(||), not(!)
- function definition
- Function/Operator is first-class object
- Lambda Expression (lambda keyword)
- Closure
- List support(and utilities like car, cdr)
This language aims an original scheme like lisp.
This is not an original specification original is can be found at the article.
Orelang provide only one grammer.
Expr := (operator args1 args2...) <- this is CallOperator
Expr := value <- this is ImmediateValue
This looks like lisp.
Original implementation of Orelang in Java uses JSON and JSONIC for Syntax Analysis.
You can write like Lisp(S-Expression) with trainspiler.
Orelang_TS provides a transpiler which converts S-Expression into internal expression of Orelang_TS(JSON Array).
