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/micro/port_wasm_stream.c | 10 +++++++++- 1 file changed, 9 insertions(+), 1 deletion(-) (limited to 'src/micro/port_wasm_stream.c') diff --git a/src/micro/port_wasm_stream.c b/src/micro/port_wasm_stream.c index 155cde4..d96ceab 100644 --- a/src/micro/port_wasm_stream.c +++ b/src/micro/port_wasm_stream.c @@ -17,7 +17,7 @@ extern void js_msg(int c); static unsigned char chunk[CHUNK]; /* the input the server has not read yet: q[qp..qn) */ static unsigned char q[QCAP]; -static int qn, qp, closed; +static int qn, qp, closed, polled; unsigned char *wasm_chunk(void) { return chunk; } int wasm_chunk_cap(void) { return (int)sizeof chunk; } @@ -38,6 +38,10 @@ int wasm_feed(int n) return 0; } +/* 1 while the server is suspended by a poll rather than by a read: the host should resume it + after the event loop has run, whether or not input came */ +int wasm_polling(void) { return polled; } + /* no more input will come: the next read past the end is -1 */ void wasm_close(void) { closed = 1; } @@ -83,6 +87,10 @@ Cell micro_syscall(Cell *mem, Cell op, Cell a, Cell b, Cell c) if (a == 2) return HEAP_HI; if (a == 3) return (Cell)micro_mem_words() * 8; return -1; + case 42: /* poll: suspend once so the host can feed what has arrived, then say if input is waiting */ + if (!polled) { polled = 1; return MICRO_WAIT; } + polled = 0; + return qp < qn; case 7: /* exit: the run ends */ return -1; case 21: /* argc: the server has no command line of its own, so alone */ -- cgit v1.2.3
