Getting started meant cloning the repository, bootstrapping a compiler and
learning a task runner called `x`. That is a contributor's workflow handed to
everyone who wants to try the language.
Installing is now one command:
curl -fsSL https://workshopsoft.pages.workshopsoft.io/ludic/install.sh | sh
install.sh puts a complete toolchain — compiler, CLI, engine runtime, bundled
ludic.* packages, formatter, language server — in ~/.ludic and adds it to PATH.
Prebuilt artifacts are checksum-verified; where a platform has none, or the
release predates this layout, it bootstraps from the compiler's own IR seed with
clang. The docs site publishes the script beside the pages that quote it, so the
page and the script can never come from different releases.
`x` becomes `ludic`, and the surface splits by audience. A user of the language
sees `new`, `run`, `build`, `test`, `add`, `fmt`, `lsp`, `doctor`, `upgrade`;
`ludic new` scaffolds a project that builds and plays as it stands. Everything
the toolchain repo needs moved under `ludic dev` — build, test, reseed,
bootstrap-cfree, docs-gen, release — unchanged apart from the namespace. Those
tasks read arguments one position further along, so dispatch_dev sets a shift
and commands use arg_n()/arg_total() rather than each knowing its own depth.
Release artifacts become complete install roots (bin/ beside runtime/, packages/
and VERSION) rather than bare binaries, which is what the installer unpacks.
`ludic dev test` asserts the whole shape: it stages an install, puts it on PATH
with no LUDIC_HOME, and runs new -> build -> test through it.

build_artifacts wrote a single dist/SHA256SUMS covering whatever that host
happened to build. But a release is assembled from more than one machine — the
Linux runner cannot produce the darwin-arm64 toolchain — and
forgejo_upload_assets deliberately skips an asset whose name is already
attached. So the first host to publish wrote SHA256SUMS, and every artifact
added later was silently left uncovered by it.
Emit one <artifact>.sha256 per tarball instead. The names are unique, so each
host's contribution stands on its own and nothing goes stale.

Implements the v1 direction decided in the RFC as a set of `x` subcommands
plus a small, contained compiler change.
* URL-as-identity, no registry — a dependency is named by its git import
path and a `git tag vX.Y.Z` publishes a version.
* Minimum Version Selection — a `require` is a minimum; the resolver picks
the greatest required minimum per module, then the reachable closure at
those versions. Deterministic, no SAT solver (tools/x/pkg.ludic).
* Content-addressed global store + per-project links — packages live once in
~/.ludic/store keyed by a content hash; each project links them under
ludic_modules/. package.ludic (manifest) + package.lock.ludic (lock).
* Namespace registration for source packages via a module-root import
fallback in the compiler: do_import resolves a non-local, non-absolute
import under $LUDIC_MODULES (default ludic_modules/), so a fetched
package's Ludic compiles into the consumer the way the built-in stdlib
does. Collisions and missing prebuilt targets are hard errors.
Commands: x add / x get / x update / x verify / x vendor. New hermetic suite
`x test-pkg` (stands up throwaway git repos, offline) is gated inside `x test`.
Existing programs compile byte-for-byte identically (the import fallback only
fires when the local path is absent); the C-free bootstrap fixpoint holds and
the seed is regenerated. Full suite: 87 passed, package suite: 12 passed.

Repository-cleanup / DX pass folding three tracker items into one coherent
change, verified green end to end (`bin/x test` 49/0, `bin/x selfhost-test`
29/0, `bin/x test-tools` 29/0).
#28 — curate & categorise examples/
- 42 flat entries regrouped into intent-revealing subdirs: games/, rendering/,
ecs/, events/, networking/, lang/, library/ (was lib/).
- chronorift dir-vs-file duplication resolved: the entry file and its import
modules now live together under games/chronorift(.ludic).
- Every path reference updated repo-wide (test runner, editor-tool drivers,
docs/site, design docs).
- New examples/README.md indexes the whole set with run commands.
- Showcase examples without a self-asserting entry (hello, events, net_rt) now
get a compile-only rot guard in `bin/x test`, so nothing here rots silently.
#30 — text-diffable golden baseline
- The 4 binary selfhost/golden/*.ppm blobs are replaced by a single
selfhost/golden/renders.sha256 manifest (SHA-256 per render). Hashes are
byte-identical to the old PPMs, so the baseline is unchanged — only its form.
- game_case now compares framebuffer hashes; a regression shows as a changed
hex line in review, not "binary files differ".
- New `bin/x golden` regenerates the manifest deliberately (review with
`git diff selfhost/golden/renders.sha256`).
#27 — PPM & asset handling
- Headless renders now write build/out.ppm, never the repo root; `x app`,
`x clean`, messaging and .gitignore updated to match. Nothing is written to
the working root any more.
- Redundant local Kenney .zip archives removed (the art ships extracted;
.gitignore already excludes *.zip). CC0 License.txt files retained.

Repository hygiene pass (issue #39):
- Add `.editorconfig` mirroring ludic-fmt: 2-space indent, LF, UTF-8, trim
trailing whitespace and final newline by default; 4-space for Python
tooling; keep trailing whitespace in Markdown (hard line breaks).
- Reconcile `.gitignore`: root-anchor `/build/` and `/out.ppm`, normalise the
misleading `**.zip` glob to `*.zip`, and document that the Kenney art is
tracked *extracted* while the download/plugin zips are local-only. `.idea`
-> `.idea/`.
- Add a `bin/x clean` command that removes `build/`, the root `out.ppm`, and
stray `bin/*.tmp`, keeping the toolchain binaries so the running `x`
survives.
No generated artifacts land outside build/ or bin/, both of which are ignored.
Closes#39

Implement the bulk of the namespaced-stdlib proposal (workshopsoft/ludic#2):
156 namespace methods across Math, Text, List, Ease, Collide, World, Net,
Sys, Save, Mem, extended Screen, Color functions, extended Random, and Time.
All deterministic fixed-point; self-hosting (C-free bootstrap fixpoint holds).
Compiler (selfhost/):
- Math.*: sqrt/sin/cos/tan/atan2/asin/acos (fixed-point runtime prelude —
bit-by-bit isqrt, 256-entry interpolated sine table, Ross atan2), plus
hypot/dist/dist2/deg_to_rad/rad_to_deg/posmod/wrap/ping_pong/snapped/
move_toward/smoothstep/lerp/remap/sign/floor/ceil/round.
- Text.* (complete): upper/lower/trim/repeat/pad, split/join/replace,
and the libc-backed queries.
- List.* (complete): insert/remove_at/remove/sort plus the earlier ops.
- Ease.* (in/out/in_out/back/bounce) and Collide.* (rects/point_rect/
circles/rect_circle).
- Phase 3: World/Net/Sys/Save namespaced over the bare builtins (byte-
identical IR) and Mem.* (bytes/words/copy/fill/peek/poke).
- Screen.* extended (line/circle/fill_circle/triangle/fill_triangle via new
runtime primitives; sprite/sprite_scaled aliases), Color.* functions,
Random.* (value/int/sign), Time.* (frame/delta/elapsed/now — new
game-loop frame counter).
- Fix a lexer bug: fixed-point literals with >4 fractional digits overflowed.
Docs & tooling:
- 129 new per-symbol doc pages; gen.py made data-driven (namespaces
discovered from the docs, no hardcoded list); new check-impl.py enforces
that every implemented namespace method / keyword / type / phase has a
doc page, wired into `x test-tools`. Document the previously-undocumented
keywords (break/continue/where/entry/new/public + and/or/not tokens).
- LSP: namespaced signature help (ns_method_sig) covering every namespace.
Tests: 12 new self-host/regression tests + a golden render for the drawing
primitives. All suites green (selfhost 21, regression 45, tools 29).

Three enable/disable statement scopes, each a reversible flag flip:
- `disable P on e` / `enable P on e` — one property on one entity. Clears
the has-flag so queries stop matching; field data persists in storage, so
enable restores it untouched. @OnDisable(P)/@OnEnable(P) handler hooks run
at the toggle point with the property bound by name.
- `disable Model` / `enable Model` — @ME_<Model> global flag; the model's
entities drop out of every query while disabled.
- `disable Handler` / `enable Handler` — @HE_<Handler> global flag; the
handler stops being called each phase while disabled.
Nothing is copied or freed — each toggle is one global store or one has-flag
store. Reduces entirely to existing ECS machinery (has-flags, kind filter,
per-phase call guards), so the data-oriented model is untouched.
New AST node S_TOGGLE; emit_toggle lowers it. Query {Model} filter now ANDs
@ME_; phase calls now guard on @HE_. Parser gains enable/disable statements
and @OnEnable/@OnDisable annotations.
Vocabulary: `on` promoted from RESERVED to CLAUSE (parser now dispatches on
it); enable/disable added as STMT keywords — synced across ludic_syntax.h,
the TextMate grammar, and LudicTokens.kt (check-vocabulary.py clean).
examples/toggle.ludic demonstrates all three scopes (prints 6 0 7 1 0);
test.sh smoke asserts it. Reseeded; C-free fixpoint holds; goldens identical.
Also: stop tracking tools/.idea/ (gitignored).

Self-hosted compiler (selfhost/*.ludic), runtime, examples, editor tooling,
and docs. Phase 1 of the syntax-redesign cohesion pass has landed:
edge-system fix, signature-query, when-alias, and the documentation truth-pass.
Suite green (14/14), C-free bootstrap fixpoint holds.
