A fallible function returns a `result` value, built with ok(payload) on success
or err(message) on failure. The caller recovers a value with `try EXPR else {
… }`: on ok the whole expression is the payload; on err the else block runs —
with the failure message bound to `error` — and its trailing expression supplies
the fallback. It is a plain branch on the result's tag: no exceptions, no hidden
control flow, nothing unwinds. is_ok(r) / is_err(r) classify without unwrapping.
Payloads are any i32-width scalar (int/fixed/bool/entity). The feature is
additive and only kicks in when ok/err/try are used, so untouched programs
compile byte-identically (verified) and the C-free bootstrap fixpoint holds.
Complements panic/assert from #8 (the unrecoverable half). The optional
top-level frame `recover` stays deferred (needs a frame-abort mechanism); the
full tagged-union/any generalization is tracked in #1.
Adds the `try` keyword and ok/err/is_ok/is_err builtins across the compiler,
the vocabulary header, JetBrains + TextMate/VSCode grammars, the docs inventory
and pages, examples/library/recover.ludic, and a regression case.

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 verifyPluginruns JetBrains' own Plugin Verifier over the built artifact against 2025.3 and reports Compatible, with no deprecated or scheduled-for-removal API usages../gradlew runIdeboots a real IDEA 2025.3 with the plugin installed. The sandbox log line to look for isLoaded 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 bin/x test-tools
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 bin/ under the project root, which is where
bin/x tools puts them.
