It extracts a +comprehensive **symbol table** and **call graph** and emits them as the canonical CLDK +`analysis.json`, or projects that same IR into a **Neo4j** property graph (`--emit neo4j`). +It mirrors its [Python](https://github.com/codellm-devkit/codeanalyzer-python) (`canpy`) +and [TypeScript](https://github.com/codellm-devkit/codeanalyzer-typescript) (`cants`) +sibling analyzers, so output-shape parity with them is a first-class concern. + +The two halves come from different tools: the **symbol table is syntactic** — built with +[JavaParser](https://javaparser.org/) + its symbol solver over the Eclipse JDT/ECJ +frontend; the **call graph is semantic** — built by WALA using **RTA** (Rapid Type +Analysis) over a class hierarchy, gated behind `-a 2`. Entrypoint discovery is +framework-aware (Spring, JAX-RS, Jakarta, Struts, Camel). + +## Architecture — follow the pipeline + +The whole analyzer is one orchestrator: `analyze()` inside +`src/main/java/com/ibm/cldk/CodeAnalyzer.java` (a picocli `@Command`). Read it first; +everything else is a stage it calls, in order: + +1. **schema short-circuit** — `--emit schema` → `Neo4jEmitter.emitSchema()` and return + (no project analysis). +2. **dependency resolution** — `BuildProject.downloadLibraryDependencies()` fetches libs + so JavaParser can resolve types. +3. **symbol table** (syntactic) — `SymbolTable.extractAll()` (or `extract()` for targeted + `-t` runs, `extractSingle()` for `-s` inline source) → `Map`. +4. **call graph** (semantic, `-a 2` only) — `SystemDependencyGraph.construct()` builds the + WALA scope + class hierarchy, discovers entrypoints (`AnalysisUtils.getEntryPoints`), + runs the RTA builder, sets cyclomatic complexity back onto callables, and returns + `List` edges (application-class targets only). +5. **output** — `--emit neo4j` → `Neo4jEmitter.emit()`; otherwise Gson serializes + `{symbol_table, call_graph, version}` to `analysis.json` (or stdout). + +The `analysis.json` shape is the **POJOs in `com.ibm.cldk.entities`** (`JavaCompilationUnit` +is the top symbol-table type; there is no single `JApplication` JSON type — `:JApplication` +is a Neo4j node). The Neo4j schema is a *separate*, versioned contract in +`neo4j/SchemaCatalog.java` — treat it as a contract enforced by conformance tests. + +## Directory map + +All packages under `src/main/java/com/ibm/cldk`. + +| Path | Responsibility | +|------|----------------| +| `CodeAnalyzer.java` | Entry point + picocli CLI + `analyze()` orchestrator — the spine | +| `SymbolTable.java` | Symbol table build (JavaParser/JDT, syntactic) | +| `SystemDependencyGraph.java` | Call graph / SDG build (WALA RTA, semantic); defines `Dependency`/`CallDependency` | +| `entities/` | Output-contract POJOs (Lombok `@Data`): `JavaCompilationUnit`, `Type`, `Callable`, `CallSite`, graph `CallableVertex`/`CallEdge`, … | +| `javaee/` | Framework-aware entrypoint finders (`spring/`, `jax/`, `jakarta/`, `struts/`, `camel/`) + CRUD finders | +| `neo4j/` | Graph projection: `Neo4jEmitter` (facade), `GraphProjector` (IR→rows), `CypherWriter` (snapshot), `BoltWriter` (incremental), `Schema`/`SchemaCatalog` (contract + `SCHEMA_VERSION`) | +| `utils/` | `BuildProject`, `ScopeUtils` (WALA scope), `AnalysisUtils` (entrypoints, app-class filter, complexity), `Log` | +| `src/test/java/com/ibm/cldk` | JUnit 5 tests; fixtures in `src/test/resources/test-applications` (daytrader8, plantsbywebsphere, …) | + +## Commands + +Build system is **Gradle** (`./gradlew`); Java **11+** (Semeru 17 recommended, GraalVM for +native).

Neo4j Bolt / Testcontainers tests are opt-in: + `RUN_CONTAINER_TESTS=1 ./gradlew test`. +- `./gradlew nativeCompile -PbinDir=$HOME/.local/bin` — GraalVM native `codeanalyzer` binary. +- `./gradlew spotlessApply` — apply formatting (also runs automatically on `compileJava`). +- `java -jar … --emit schema > schema.neo4j.json` — regenerate the Neo4j schema contract. +- `./gradlew bumpVersion -PbumpType=patch|minor|major` — version bump. + +## I implement features myself — you assist + +For feature work, **I write the implementation** to stay fluent in my own analyzer. +Act as a helper, not the author: + +- **Don't write the feature code** or apply edits to implement it unless I explicitly + ask ("write this", "implement X", "apply it"). Default to guiding, not doing. +- **Do** move me fast: explain the relevant stage, point at prior art (e.g. an existing + entrypoint finder in `javaee/` as the template for a new framework), sketch + signatures/types, outline an approach, and answer questions about the codebase. +- **Review on request:** when I share a diff or push, critique it — correctness, + **parity with the Python/TypeScript backends**, schema conformance, missing tests, edge + cases — and suggest concrete improvements. +- Scaffolding like tests or boilerplate is fine **when I ask**; otherwise leave the + keyboard to me. +- If you think I'm about to go wrong, say so briefly and let me decide — don't pre-empt + by implementing the fix. + +## Rules + +1. **Think before coding.** State assumptions explicitly; ask rather than guess. Push + back when a simpler approach exists. Stop when confused. +2. **Simplicity first.** Guide me toward the minimum idiomatic code that solves the + problem. Nothing speculative; no abstractions for single-use code. +3. **Issue → branch → work → PR.** Every change starts as an issue, on a branch named + `feat/issue-XXX`, `fix/issue-XXX`, `chore/issue-XXX`, and lands via a PR. +4. **Guard the contract.** Changes to `com.ibm.cldk.entities` or Neo4j output must keep + parity with the sibling analyzers and pass `Neo4jSchemaConformanceTest` (which also + asserts the checked-in `schema.neo4j.json` is current). + +## Goal-driven execution, as a teaching loop + +Success is measured by the sole fact that **I understand it**. The success criterion: +I can point to the exact line of code where any feature lives, however remote or +obscure, and explain why it's there and how it behaves. + +To that end, be my teacher and a Socratic one — not an answer key: + +- Lead with questions that make me derive the answer; don't hand me the solution. +- Verify understanding, not just behavior — have me locate and explain the relevant + LOC, walk edge cases, and predict what a change would do before running it. +- Teach, help improve, and strengthen the weak spots you surface; circle back to them. +- The loop closes when I can **teach it back** and place every feature on a line, not + merely when the tests pass. +- Over the session, frequently — but not so much that I am stymied — ask spaced + repetition questions so concepts are internalized. + +Learning progress is tracked globally, not per-repo: see the SRS deck and the +"continual learning" defaults in `~/.claude/CLAUDE.md`. + +# Auxiliary support tasks + +## Tidy up the release announcement + +Every `vX.Y.Z` tag makes the release workflow (`.github/workflows/release.yml`) auto-post an +announcement to the **Announcements** discussion (this repo, and the org mirror in +`codellm-devkit/.github`). That body is machine-generated from PR titles — it mis-categorizes +changes, includes `chore(release)` noise, and buries breaking changes. + +When you're working in this repo, check whether the latest release's announcement still needs +cleanup, and if so, fix it: + +1. **Find it.** `gh release view --json tagName,publishedAt`; then list recent discussions via + `gh api graphql` (repository → discussions), match category `Announcements` whose title carries + this release's version (the auto-post titles it `vX.Y.Z`; a cleaned-up one is + `📣 New Release: codeanalyzer-java X.Y.Z`). Keep the discussion node `id` and read its `body`. +2. **Skip if already done.** If the body starts with `` (or already reads as a + clear, human-written announcement), do nothing. +3. **Otherwise rewrite it** into a clear, user-facing announcement, grounded in `CHANGELOG.md` and + the referenced PRs/diff (not the auto-grouping — verify each change; never invent anything): + - **breaking changes first**, each with a one-line migration step; + - plain-language highlights (what it does, not the PR title); + - upgrade lines — `pip install -U "codeanalyzer-java==X.Y.Z"`, or the shell installer + one-liner (`curl … codeanalyzer-installer.sh | sh`); + - links to the GitHub release and `CHANGELOG.md`. +4. **Update in place.** Edit the discussion with the GraphQL `updateDiscussion` mutation (don't + open a new one): set the title to `📣 New Release: codeanalyzer-java X.Y.Z`, prepend + `` to the body, and mirror the same title and body to the org discussion. + This task only reads code and edits Discussions — it makes no commits. diff --git a/GEMINI.md b/GEMINI.md new file mode 120000 index 0000000..681311e --- /dev/null +++ b/GEMINI.md @@ -0,0 +1 @@ +CLAUDE.md \ No newline at end of file
