From 1c53304d03414890af0da7432d1aea87e754a14a Mon Sep 17 00:00:00 2001 From: Moon Flower Date: Wed, 14 Oct 2026 08:29:46 +0330 Subject: feat: grow memory limits, add icon/actor libraries, overhaul LSP diagnostics Compiler and VM - make every memory map limit dynamic and adjustable at both build time and runtime, including compiler tables, stacks, and every execution region - reserve and grow tables, operand and return stacks, frame segments, and image-building output without relocating live code or globals - rename i/o and string helpers consistently (puts -> put_s, putn -> put_n, scat -> cat_s) across compiler, runtime, examples, tests, and docs - recast and consume values assigned to globals from inside functions - allow fixed and const together, add typed closure returns (fn:t(...)), multi-include syntax (include rt, run, core;), and recurse type inference - never infer string literals as word, anywhere, as argument, variable, or return type - draft docs/BORROW.md: a borrow checker less intrusive than Rust's but more intelligent LSP and editor integration - require explicit includes and give every toolchain area its own namespace (rt, lsp, run, core) - hover for built-in types, inferred types, values known at hover time, array and pointer lifetime/size, library names in include statements, and inferred lifetimes with explanations - honor /* */ comments as documentation for variables and arguments, and stop misattributing section headers or trailing comments as variable hints - stream diagnostics and cancel stale requests on change - jump to definition and references, including cross-file - quick fixes with automatic library import, and namespace completion Hints and diagnostics - render hints as blue squigglies by default, with hints on/small/off per file - suppress magic-number hints via a preceding /* */ comment, and say so - warn on unused arguments; allow multiple _ discards in parameters, pattern matching, and tagged enums, warning if a _ is actually used - rewrite hint and comment prose in professional compiler-doc register Libraries - add icon.zc: run-time self-modification, find/replace syntax, type and block edits, and step-through inspection of locals and globals - add actor.zc: async actors with Actor, implicit this, spawn/recv/send, injected into the compiler machinery at include time rather than built in Tooling and docs - reorganize sources, tests, and designs into subdirectories - unify windows entry points in tinyvm.bat and add a matching tinyvm.sh - add --help across the toolchain - polish the learning guide, stdlib docs, and design notes Tests - add accept, reject, and regression coverage across the compiler, LSP, - runtime, icon, actors, threads, formatting, and the toolchain contracts, plus fuzzers and property tests --- tests/programs/share.zc | 71 ++++++++++++++++++++++++++++++------------------- 1 file changed, 44 insertions(+), 27 deletions(-) (limited to 'tests/programs/share.zc') diff --git a/tests/programs/share.zc b/tests/programs/share.zc index e9c381f..91a3918 100644 --- a/tests/programs/share.zc +++ b/tests/programs/share.zc @@ -1,34 +1,51 @@ +namespace;
