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 --- src/core/io_linux.c | 33 ++++++++++++++++++++++++++++++--- 1 file changed, 30 insertions(+), 3 deletions(-) (limited to 'src/core/io_linux.c') diff --git a/src/core/io_linux.c b/src/core/io_linux.c index 8a024aa..aaf6a18 100644 --- a/src/core/io_linux.c +++ b/src/core/io_linux.c @@ -1,4 +1,5 @@ #include +#include #ifdef _WIN32 #include #include @@ -7,7 +8,12 @@ #include #endif -int J; +#if !defined(_WIN32) && !defined(__wasm__) +#define VM_TLS _Thread_local +#else +#define VM_TLS +#endif +VM_TLS int J; #ifdef _WIN32 static int pk(void){int c=getchar();ungetc(c,stdin);return c==EOF;} @@ -19,8 +25,8 @@ char Q(void){int c=getchar();J=pk();return c;} one would wait for a message that comes only after the answer. so J is 1 only when the end is known, and 0 when more may come. the output is flushed before any read that can wait, for the same reason. */ -static unsigned char ib[65536]; -static int ip, in, ieof; +static VM_TLS unsigned char ib[65536]; +static VM_TLS int ip, in, ieof; /* make a byte available. wait is 0 to look without waiting. returns 1 when one is ready */ static int fill(int wait) { @@ -46,6 +52,27 @@ char Q(void) return (char)c; } #endif +/* 1 when a byte can be read without waiting: buffered, or already on the pipe */ +int input_pending(void) +{ +#ifdef _WIN32 + return 0; +#else + return fill(0); +#endif +} +#ifndef _WIN32 +struct IoSnapshot { unsigned char bytes[65536]; int position, count, ended, flag; }; +size_t io_context_size(void) { return sizeof(struct IoSnapshot); } +void io_context_snapshot(void *destination) { + struct IoSnapshot *snapshot = destination; + memcpy(snapshot->bytes, ib, sizeof ib); snapshot->position = ip; snapshot->count = in; snapshot->ended = ieof; snapshot->flag = J; +} +void io_context_restore(const void *source) { + const struct IoSnapshot *snapshot = source; + memcpy(ib, snapshot->bytes, sizeof ib); ip = snapshot->position; in = snapshot->count; ieof = snapshot->ended; J = snapshot->flag; +} +#endif void G(char c){putchar(c);} static void init_io(void) { -- cgit v1.2.3
