From 74117595d2e24597b332273b77de8f152361d1bb Mon Sep 17 00:00:00 2001 From: dimgigov Date: Sun, 31 May 2026 18:14:35 +0300 Subject: [PATCH] Phase 7.10: multi-file project build, module braces, else-if fix, UTF-8 lexer MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Runtime (stdlib/runtime.c): - bux_list_dir() — directory listing with extension filter - bux_run_cc() — invoke C compiler on generated C code - bux_mkdir_if_needed() — create build directory - bux_dir_exists() — check if directory exists - Removed duplicate bux_path_join Parser (src_bux/parser.bux): - Module parsing with braces: module X { ... } - else-if parsing: wraps inner if in synthetic Block - Infinite-loop safeguards in module body and struct body parsing Lexer (src_bux/lexer.bux): - lexPeek: mask with & 255 to handle UTF-8 signed char bytes CLI (src_bux/cli.bux): - Cli_BuildProject(): multi-file build from src/ directory - Lists .bux files, parses each, merges declarations inline - Runs sema + HIR + C codegen on merged module - Invokes C compiler to produce binary - New extern declarations: bux_file_exists, bux_dir_exists, bux_path_join, bux_mkdir_if_needed, bux_run_cc, bux_list_dir - FileExists(), DirExists() wrapper functions - "project" command dispatch Known issue: else-if chain not fully emitted by buxc2 C backend (lexSkipWhitespace missing comment handling in generated C). All 18 examples pass, all unit tests pass. --- _selfhost/src/cli.bux | 185 +++++++++++++++++++++++++++++++++++++++ _selfhost/src/lexer.bux | 2 +- _selfhost/src/parser.bux | 91 ++++++++++++++++++- src_bux/cli.bux | 185 +++++++++++++++++++++++++++++++++++++++ src_bux/lexer.bux | 2 +- src_bux/parser.bux | 91 ++++++++++++++++++- stdlib/runtime.c | 79 +++++++++++++++++ 7 files changed, 627 insertions(+), 8 deletions(-) diff --git a/_selfhost/src/cli.bux b/_selfhost/src/cli.bux index 9495829..a8a6a9e 100644 --- a/_selfhost/src/cli.bux +++ b/_selfhost/src/cli.bux @@ -6,6 +6,12 @@ extern func PrintLine(s: String);
