Orkuncakilkaya 5a9e8cb2da Phase 8a: finish typed indexing — fixeds/ptrs buffers (retire peekf/pokef/peekp/pokep/str_len)
The last peek/poke pairs were the same "typed buffer access wearing a C name" as
peek8/peek32, so they become indexing too:

  peekf(sc_x, i)     -> sc_x[i]        (a `fixeds` buffer -> a fixed)
  pokep(gc_bmp, s,b) -> gc_bmp[s] = b  (a `ptrs` buffer -> a pointer)
  str_len(s)         -> len(s)         (len is polymorphic since 7f; str_len was dead)

Two new element-typed buffers join words: `fixeds` (32-bit fixed) and `ptrs`
(pointer, 8-byte stride). emit_index_addr dispatches on the base type; IR is
byte-identical to the old intrinsics.

The peekf/peekp buffers (ed_x0/ed_x1/ol_x/sc_x fixed coords; gc_bmp/img_px/
tt_data/ui_text pointer arrays) were retyped scope-aware, then the 33 sites
migrated to indexing. Two bugs found via a menu golden diff / a link-time type
error and fixed: the buffer-name regex truncated digit suffixes (ed_x0 -> ed_x),
and the char-literal brace-miscount skipped a few module declarations (same class
as 7j).

Reseeded (22371 lines); C-free fixpoint holds; goldens byte-identical; 18/18;
vocab (fixeds/ptrs types in, 5 intrinsics out) + doc-fences clean.

Ludic for JetBrains IDEs

Works in IntelliJ IDEA (Community and Ultimate), CLion, GoLand, PyCharm, Rider, WebStorm — anything on the IntelliJ Platform 2023.2 through 2026.2 (since-build 232, until-build 262.*).

until-build 262 is deliberately ahead of the newest released platform — 2025.3 is build 253, and no 262 IDE exists yet. That headroom is the point: an until-build pinned to today's IDE gets the plugin auto-disabled the moment a user upgrades.

Two things are machine-checked rather than assumed, because a plugin that packages cleanly can still fail to load:

  • ./gradlew verifyPlugin runs JetBrains' own Plugin Verifier over the built artifact against 2025.3 and reports Compatible, with no deprecated or scheduled-for-removal API usages.
  • ./gradlew runIde boots a real IDEA 2025.3 with the plugin installed. The sandbox log line to look for is Loaded custom plugins: LSP4IJ (0.20.1), Ludic (1.0.0) in .intellijPlatform/sandbox/Ludic/IC-2025.3/log/idea.log.

If the plugin does not appear in Settings -> Plugins after installing, the cause is almost always that the IDE's build number is outside since-build..until-build. IntelliJ installs the declared dependency (LSP4IJ) from Marketplace first and only then rejects the incompatible plugin, so the symptom is "LSP4IJ got installed, mine did not". Check Help -> About for the build number and widen pluginUntilBuild in gradle.properties to match.

Building

Gradle must run on JDK 17–21. A newer JDK fails with a bare version number as the error message, which is not obvious the first time you see it:

export JAVA_HOME=$(/usr/libexec/java_home -v 21)     # macOS
cd tools/editors/jetbrains
./gradlew buildPlugin        # -> build/distributions/Ludic-1.0.0.zip
./gradlew runIde             # try it in a sandbox IDE

The first build downloads an IntelliJ IDEA Community distribution (over 1 GB), so expect it to take a while; later builds take seconds. Once the cache is warm,

LUDIC_TEST_JETBRAINS=1 ./tools/test-tools.sh

includes the plugin build in the toolchain's own test run.

Install the zip with Settings -> Plugins -> ⚙ -> Install Plugin from Disk. LSP4IJ is a required dependency; the IDE offers to install it for you.

Settings

Settings -> Languages & Frameworks -> Ludic — the path to ludic-lsp and to ludicc. Both default to build/ under the project root, which is where tools/build-tools.sh puts them.
