Abrvalg is a Python-like programming language interpreter.
The project contains:
- Regular expression based lexer
- Top-down recursive descent parser
- AST-walking interpreter
- REPL
Abrvalg doesn't require any third-party libraries.
What the language looks like:
func map(arr, fn):
r = []
for val in arr:
r = r + [fn(val)]
r
func factorial(n):
if n <= 1:
1
else:
n * factorial(n - 1)
print(map(1...10, factorial))You can find more examples in tests directory.
How to try it:
git clone https://github.com/akrylysov/abrvalg.git
cd abrvalg
python -m abrvalg tests/factorial.abr
