Signed-off-by: erick-alcachofa <erick@artichoke.dev> This commit addresses subtle state-management issues uncovered while exercising tokenizer move semantics and operator parsing. Moved-from instances were retaining stale iterators and metadata that could manifest as incorrect token offsets when the objects were reused. Additionally, token location bookkeeping during comment skipping and operator backtracking drifted from the iterator, producing inaccurate column reports. - Refines the move constructor by exchanging `line`, `column`, `iter`, `tokensGenerator`, `tokensBuffer`, and `source`, ensuring moved-from tokenizers reset to neutral defaults without dangling references. - Aligns the move assignment operator with the constructor by using `std::exchange` across all transferred members, preventing stale state when a tokenizer is reassigned. - Adjusts column advancement for single-line comments so the cursor increments by one when skipping the comments sequence, matching the iterator progression. - Promotes the operator trie to a function-local static cache, avoiding repeated construction each time an operator token is read. - Restores accurate token metadata by assigning the original line and column (`cLine`, `cColumn`) when emitting operator tokens and rolling back the column alongside the iterator during longest-valid backtracking.
⚠️ WIP Highly Experimental Project
- The language, compiler, and tools are under active development and may be very unstable.
- There will likely be breaking changes and periods where no work is done on the project.
- Expect breaking changes as the compiler progresses through semantic analysis and code generation.
The artichoke Programming Language
artichoke is a modern, statically-typed programming language designed to
satisfy my personal preferences and requirements for programming, combining the
low-level control and powerful modern features like a robust type system,
generics, integrated error handling, and a clean, ergonomic syntax.
The goal of artichoke is to provide a language that is simple, safe, and
productive for programming, eliminating common pitfalls without sacrificing
performance or control.
For a detailed guide to the language, grammar specification, and syntax features, please see the project wiki
Core Philosophy & Features
artichoke is built around a few core principles to create a safer, more
productive programming experience:
- Explicitness: Type conversions and error handling are explicit.
- Safety: Non-nullable pointers, a robust type system, and deterministic resource management are prioritized.
- Unambiguous Design: A grammar designed for fast, single-pass parsing and clear error reporting.
- Modern Ergonomics: Features like generics, defer, and a clean module system reduce boilerplate and improve readability.
The language includes a powerful generic type system, first-class error handling, a full suite of control flow statements (including match), a true module system, and compile-time reflection.
Project Status
artichoke is currently in the early implementation phase. The front-end
infrastructure is not yet defined but contains a simple program for printing and
visualizing the generated AST, development has shifted now toward semantic
validation.
- Lexical Analysis: Full tokenizer implementation.
- Syntactic Analysis: Handwritten Recursive Descent + Pratt Expression Parser.
- AST Infrastructure: Complete Abstract Syntax Tree with Graphviz and String-Graph based visualization support.
- Semantic Analysis (In Progress): Multi-pass symbol table generation and type checking.
- Backend: Code generation and optimization.
