[sub_pl]: Writing my first programming language
I’m learning about compilers and interpreters, so i decided to create my own programming language from scratch, that means no llvm (or other backends), no lexing or parsing librairies.
This is the list of things i learn (and/or did) until now with this project:
- I implemented the lexer part of the language without allocating memory,
- Memory management is hard, so i used an arena allocator for my ast
- Designing my language seems as hard as implementing it
- There is no priority of operations, expressions are group left associatives except when explicitly set with parentheses. that means
p.x + 1 * 2is parsed as(((p.x) + 1) * 2),1 + p.x * 2is parsed as(((1 + p).x) * 2), - I print human readable errors when parsing failed instead of just doing asserts and print stack trace.
I’m really new to compilers/interpreters, so any suggestion is good.
This is my first post in community server, so my style of writing can be a little bit clunky.
Also one of my next projects is going to be create a programming language using this language (sub_pl) to generate qbe ir.
