* rt: exact-size heap bounds; n, the words new asked for, lives in bits 32..62 ↵Gravatar zinc 13 days1-1/+1

* embed: tests, editor support and docs; js vm file access; test fixesGravatar zinc 13 days1-4/+29
| | | | | | | | | | | | | | | | | | | | embed declarations get accept and reject fixtures, a run-only image check through zc0, an lsp keyword hover and the grammar keyword. errors point at the declaration and still declare the name, so its uses are not reported again. zc0 tracks byte-string globals and lays embedded arrays out one word per element, the way its own indexing reads them. the command-line javascript vm reaches node's file system for the file syscalls, so include and embed work there; other embedders opt in. the web build is self-contained in build/web with its examples. README, BORROW and BOOTSTRAP-OWNERSHIP describe the new build and ownership rules, and ONBOARD.md is a reading and verification order for the code. the suite passes the map header to mklayout, the wasm fuzz program uses the include format, and lsp drivers scale their deadlines on hosts without the arm64 jit (ZC_TEST_TIMEOUT_SCALE). LLVM_CONFIG selects an llvm with headers for the llvm section.
* build: embed images with #embed, keep everything generated in build/Gravatar zinc 13 days1-6/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | the cores take their genome in with c23 #embed through src/core/genome.h, so images are plain little-endian word files (genome.bin) instead of generated c headers. zc0 writes that format, mkgenome checks an image against its map and shows a compiler's diagnostics when it gets them, and the javascript vm and the editor's vm host read the same files. src/tools/findcc.sh picks a compiler with #embed (clang 19 or gcc 15). zc gets an embed declaration, embed "file" as [type] name, for globals and locals: a byte string by default, char*, numbers read little-endian, and arrays of numbers. the compiler and language server carry their library and source texts through it, so embed.sh and the text it spliced into compiler.zc are gone. make writes executables to build/bin, the default map to build/core/map, the web page to build/web and the extension staging to build/vsix, and the genome now rebuilds when its sources change. the test suite lays out its own map and bootstrap and reads nothing from build/. also: rt.put_s of a byte string in zc0 images, retained function sources no longer count as live objects, a missing include no longer cascades into undefined-name errors, consecutive comment lines join into one hover paragraph, and stale test fixtures follow the include format.
* build: generate everything into build/, keep src/ free of generated filesGravatar Moon Flower 13 days1-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | src/ carried 8.4 MB of build output: the genome header, the javascript vm and its layout, and the language-server image, plus a second copy of the extension server under editors/vscode/server/. none of it is source. - move the genome from src/core/genome.h to build/core/genome.h and compile with -Ibuild/core; `make all` bootstraps one when it is missing - write genome.json, layout.ts, layout.js and lsp.json to build/js/ - compile tinyvm.ts to build/js/, typed by a tracked src/js/layout.d.ts so the vm needs no generated file beside its source - build the wasm server into build/editors/vscode/server/ and stage the whole server into editors/vscode/server/ only while mkvsix.sh packages it - redirect the test suite, image_run.js, tinyvm.sh, tinyvm.bat, test_win.ps1 and the baremetal build at the new paths, and add make lspimage and make vsix - stop tracking every generated file also fix a build blocker: lookup_raw compared skind against K_VAR, which was never declared, so `make genome` could not run at all. the guard is about emitted program globals, which are K_GVAR and K_GARR. tests/test.sh -q reports 159 passed and 21 failed both before and after this change; every failure is pre-existing and comes from the checked-in genome being stale relative to src/, plus the bootstrap above.
* feat: grow memory limits, add icon/actor libraries, overhaul LSP diagnosticsGravatar Moon Flower 13 days1-0/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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<I,O>, 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
