From f4027cae775e3c9c237675f9df35a744d54f3f2e Mon Sep 17 00:00:00 2001 From: Ben Bridle Date: Mon, 28 Oct 2024 19:52:29 +1300 Subject: Rewrite assembler This is an almost complete rewrite of the entire assembler from the ground up, with a different parsing strategy and a whole new symbol resolution mechanism for automatically including library files. The assembly syntax has also been slightly modified, with padding tokens now being prefixed with '#' instead of '$', and a block-style anonymous-label syntax which uses the '{' and '}' characters. --- src/lib.rs | 35 +++++++++++++++++------------------ 1 file changed, 17 insertions(+), 18 deletions(-) (limited to 'src/lib.rs') diff --git a/src/lib.rs b/src/lib.rs index a657354..ff00605 100644 --- a/src/lib.rs +++ b/src/lib.rs @@ -1,21 +1,20 @@ -mod addressing; -mod syntactic_token; -mod semantic_token; -mod tokenizer; -mod error; -mod assembler; +#![feature(io_error_more)] +#![feature(map_try_insert)] -pub use addressing::{CharAddress, SourceLocation, BytecodeLocation}; -pub use syntactic_token::{SyntacticToken, SyntacticTokenType}; -pub use semantic_token::{SemanticToken, SemanticTokenType, LabelDefinition, MacroDefinition}; -pub use error::Error; -pub use tokenizer::TokenIterator; -pub use assembler::Assembler; -pub fn assemble(source_code: &str) -> (Vec, Vec) { - let mut assembler = Assembler::new(); - assembler.tokenise_source(source_code); - assembler.resolve_references(); - assembler.generate_bytecode() -} +mod gather_libraries; +mod symbol_resolver; +pub use gather_libraries::*; +pub use symbol_resolver::*; + +mod locators; +mod tokens; +mod translators; + +pub use locators::*; +pub use tokens::*; +pub use translators::*; + +mod print; +pub use print::*; -- cgit v1.2.3-70-g09d2
