Master <45430047+AuroraMaster@users.noreply.github.com> Date: Tue, 12 May 2026 17:06:20 +0800 Subject: [PATCH 03/11] [rust-salvo] Modernize generator for Salvo 0.93 and refresh deps Bring rust-salvo up to current Salvo idioms after the long rebase against upstream master. The generator was previously pinned to Salvo 0.73 with deprecated `<>` path syntax, a non-existent `salvo-cors` crate, a broken `lambdaVersion` lambda reference, and a base64 0.21 API that no longer compiles on the 0.22 line. Highlights: - Cargo.mustache: salvo 0.73 -> 0.93, validator 0.18 -> 0.20, drop the fake `salvo-cors` dependency (cors is a salvo feature), pin tokio to the macros/rt-multi-thread/signal subset, add base64/async-trait. - Codegen: stop converting OpenAPI `{id}` paths to the deprecated `` syntax; Salvo 0.76+ matches OpenAPI directly. Push boolean option defaults into additionalProperties so templates and tests can rely on them. - handlers.mustache: rewrite to use `salvo::oapi::extract::{JsonBody, PathParam, QueryParam, HeaderParam, FormBody}` instead of mixing the oapi endpoint macro with the legacy `#[salvo(extract(...))]` attribute. Triple-stash `dataType` so generics like `Vec` aren't HTML-escaped. - handlers-mod.mustache: iterate `apis` by tag (one `pub mod` per API group) instead of iterating operations, which produced duplicates. - middleware.mustache: switch base64 to the 0.22 `Engine` API and stop bubbling a `Result` out of a `()`-returning handler. - models.mustache: derive `salvo::oapi::ToSchema` so generated models can flow through `JsonBody` and friends. Triple-stash `dataType`. - Add `bin/configs/manual/rust-salvo-petstore.yaml` so samples can be regenerated through the standard flow. - Tests: align fixtures with the new output (salvo 0.93, validator 0.20, modern auth struct names, per-tag handler module names). Known follow-ups: a full petstore generation still has ~21 remaining `cargo check` errors around inline-enum duplication and ToSchema coverage; those require model-template work to reach axum-level parity. --- CLAUDE.md | 104 ++++++++++++++++++ bin/configs/manual/rust-salvo-petstore.yaml | 11 ++ .../languages/RustSalvoServerCodegen.java | 38 +++---- .../main/resources/rust-salvo/Cargo.mustache | 54 +++++---- .../rust-salvo/handlers-mod.mustache | 8 +- .../resources/rust-salvo/handlers.mustache | 64 ++++------- .../main/resources/rust-salvo/lib.mustache | 11 +- .../resources/rust-salvo/middleware.mustache | 7 +- .../main/resources/rust-salvo/models.mustache | 11 +- .../main/resources/rust-salvo/routes.mustache | 22 ++++ .../rust/RustSalvoServerCodegenTest.java | 55 ++++++--- 11 files changed, 260 insertions(+), 125 deletions(-) create mode 100644 CLAUDE.md create mode 100644 bin/configs/manual/rust-salvo-petstore.yaml create mode 100644 modules/openapi-generator/src/main/resources/rust-salvo/routes.mustache diff --git a/CLAUDE.md b/CLAUDE.md new file mode 100644 index 000000000000..40e740987f3a --- /dev/null +++ b/CLAUDE.md @@ -0,0 +1,104 @@ +# CLAUDE.md + +This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository. + +## What this project is + +OpenAPI Generator is a Java tool that takes an OpenAPI 2.0/3.x spec and emits SDKs, server stubs, docs, and config files for 80+ languages/frameworks. The generators themselves are written in Java; the per-language output is driven by [Mustache](https://mustache.github.io/) templates plus generated Petstore samples that double as regression fixtures. + +JDK 11 is required (`maven.compiler.source/target=11`). Build is Maven (`./mvnw`), with a Gradle wrapper used only by the Gradle plugin module. + +## Top-level layout + +- `modules/openapi-generator` — codegen core, every language generator (`languages/*Codegen.java`), all Mustache templates (`resources//`), and the JUnit tests (`src/test/java/...`). +- `modules/openapi-generator-cli` — the runnable CLI jar (`openapi-generator-cli.jar`). Always rebuild this when iterating on a generator. +- `modules/openapi-generator-maven-plugin`, `openapi-generator-gradle-plugin` — build-tool wrappers, mostly independent of the codegen module. +- `modules/openapi-generator-online` — Spring Boot service that exposes generation over HTTP. +- `bin/configs/*.yaml` — one YAML per generator/variant; drives `bin/generate-samples.sh` which regenerates `samples/...`. +- `samples/` — generated client/server projects committed to git. They function as golden files: a generator change usually produces a sample diff that must be committed. +- `docs/generators/*.md` — auto-generated reference docs for each generator (regenerated by `bin/utils/export_docs_generators.sh`). +- `new.sh` — scaffolds a new generator (Java class + minimal template set + bin/configs entry). Always start new generators from this. + +## Common commands + +Build the CLI jar (skips tests + javadoc, ~fast): +``` +./mvnw clean install -DskipTests -Dmaven.javadoc.skip=true +``` + +Run the CLI: +``` +java -jar modules/openapi-generator-cli/target/openapi-generator-cli.jar help +java -jar modules/openapi-generator-cli/target/openapi-generator-cli.jar list # all generator names +``` + +Run the unit tests for a single generator class: +``` +./mvnw -pl modules/openapi-generator test -Dtest=RustSalvoServerCodegenTest +./mvnw -pl modules/openapi-generator test -Dtest=DefaultCodegenTest#someSpecificMethod +``` + +Regenerate one (or a glob of) sample(s) — builds the jar first if missing: +``` +./bin/generate-samples.sh ./bin/configs/python.yaml +./bin/generate-samples.sh ./bin/configs/rust-*.yaml +``` + +Iterate on templates only (no Java rebuild) — point at the resource dir with `-t`: +``` +java -jar modules/openapi-generator-cli/target/openapi-generator-cli.jar generate \ + -i some-spec.yaml -g rust-salvo -o /tmp/out \ + -t modules/openapi-generator/src/main/resources/rust-salvo +``` + +Run integration tests for a generated sample (requires the language toolchain locally; some need a running Petstore server): +``` +mvn integration-test -f samples/client/petstore/python/pom.xml +``` + +Regenerate the per-generator docs after changing options: +``` +./bin/utils/export_docs_generators.sh +``` + +After changing a generator, the expected workflow before opening a PR is: rebuild the CLI jar → regenerate every affected sample → commit the `samples/` diff alongside the code change. `bin/utils/ensure-up-to-date` is the script CI runs to verify this. + +## Architecture + +### Generator pipeline + +1. `DefaultGenerator` (`org.openapitools.codegen`) drives the run: parse spec → resolve a `CodegenConfig` implementation by name → for each operation/model/supporting-file, build a Mustache context and render via a `TemplatingEngineAdapter`. +2. `CodegenConfig` is the SPI. Each language ships one concrete subclass (usually extending `DefaultCodegen` or a per-language `Abstract*Codegen`) under `languages/`. The class declares: + - `getName()` — the `-g` value users pass. + - `embeddedTemplateDir()` / `setTemplateDir(...)` — defaults to `modules/openapi-generator/src/main/resources//`. + - `supportingFiles` — non-per-operation files (Cargo.toml, README, etc.) added in the constructor. + - `apiTemplateFiles` / `modelTemplateFiles` — per-operation / per-model template → suffix mappings. + - CLI options registered via `cliOptions.add(new CliOption(...))`. + - Per-language data-shape overrides (`toModelName`, `toVarName`, `toEnumVarName`, `postProcessOperationsWithModels`, etc.). +3. The class is registered in `modules/openapi-generator/src/main/resources/META-INF/services/org.openapitools.codegen.CodegenConfig` (one fully-qualified class name per line). Missing this entry = generator invisible to the CLI even if compiled. +4. Mustache lookup order: `templateDir` (if user-provided via `-t`) → `embeddedTemplateDir` on the classpath. This is what makes the `-t` iteration loop work. + +### Template variables + +Templates receive `CodegenModel`, `CodegenOperation`, `CodegenParameter`, `CodegenProperty`, `CodegenResponse`, etc. Names map 1:1 to fields on those Java classes; vendor extensions surface as `vendorExtensions.x-foo`. The per-language `Abstract*Codegen` is the source of truth for naming rules — when adding behavior, prefer overriding the existing extension points there rather than rewriting raw strings in templates. + +### Tests + +- `AbstractOptionsTest` subclasses verify CLI option wiring. +- Per-generator `*CodegenTest` classes drive a fake spec through the codegen and assert on either `CodegenOperation`/`CodegenModel` fields or rendered output snippets — see `RustSalvoServerCodegenTest` for an example. +- `AllGeneratorsTest` and `ArchUnitRulesTest` enforce cross-cutting invariants (every generator must run end-to-end, package structure rules, etc.); breaking these usually means a generator class is missing a registration or a required override. + +### Adding/changing a generator + +Use `./new.sh -n -s` (server) / `-c` (client) / `-t` (also scaffold a test) — it creates the codegen class, the resources directory with the minimum templates, the `bin/configs/-petstore-new.yaml`, and updates the SPI file. Then iterate by regenerating the sample and inspecting the diff. + +## Conventions + +- Vendor extensions: lower-case-hyphen for cross-language (`x-is-unique`), `x--` for language-specific (`x-java-feign-retry-limit`). Treat them as the preferred extension point before adding a new CLI option. +- New CLI options are discouraged — prefer custom templates via `-t`. See `CONTRIBUTING.md`. +- Don't hand-edit anything under `samples/` or `docs/generators/` — both are regenerated outputs. Commit the regenerated versions alongside the source change. +- `git config core.autocrlf input` is the recommended setting; samples contain a mix of platforms. + +## Current in-progress work + +The working tree has unfinished changes to the `rust-salvo` server generator: modifications to `RustSalvoServerCodegen.java`, its test, and `Cargo.mustache`/`handlers.mustache`/`lib.mustache`, plus an untracked `routes.mustache`. There is no `bin/configs/rust-salvo*.yaml` yet, so samples cannot be regenerated through the standard `generate-samples.sh` flow until one is added. The SPI registration is already in place (`RustSalvoServerCodegen` line in `org.openapitools.codegen.CodegenConfig`). diff --git a/bin/configs/manual/rust-salvo-petstore.yaml b/bin/configs/manual/rust-salvo-petstore.yaml new file mode 100644 index 000000000000..30fb04bbe3fe --- /dev/null +++ b/bin/configs/manual/rust-salvo-petstore.yaml @@ -0,0 +1,11 @@ +generatorName: rust-salvo +outputDir: samples/server/petstore/rust-salvo/output/petstore +inputSpec: modules/openapi-generator/src/test/resources/3_0/petstore.yaml +templateDir: modules/openapi-generator/src/main/resources/rust-salvo +generateAliasAsModel: true +additionalProperties: + hideGenerationTimestamp: "true" + packageName: petstore_salvo + homePageUrl: https://github.com/openapitools/openapi-generator +globalProperties: + skipFormModel: false diff --git a/modules/openapi-generator/src/main/java/org/openapitools/codegen/languages/RustSalvoServerCodegen.java b/modules/openapi-generator/src/main/java/org/openapitools/codegen/languages/RustSalvoServerCodegen.java index 4efed43dacd7..c7c9d985d34c 100644 --- a/modules/openapi-generator/src/main/java/org/openapitools/codegen/languages/RustSalvoServerCodegen.java +++ b/modules/openapi-generator/src/main/java/org/openapitools/codegen/languages/RustSalvoServerCodegen.java @@ -196,8 +196,7 @@ private void setupCliOptions() { .defaultValue(Boolean.FALSE.toString()), new CliOption("enableCorsMiddleware", "Enable CORS middleware") - .defaultValue(Boolean.FALSE.toString()), - + .defaultValue(Boolean.FALSE.toString()) ));

Always rebuild this when iterating on a generator. -- `modules/openapi-generator-maven-plugin`, `openapi-generator-gradle-plugin` — build-tool wrappers, mostly independent of the codegen module. -- `modules/openapi-generator-online` — Spring Boot service that exposes generation over HTTP. -- `bin/configs/*.yaml` — one YAML per generator/variant; drives `bin/generate-samples.sh` which regenerates `samples/...`. -- `samples/` — generated client/server projects committed to git. They function as golden files: a generator change usually produces a sample diff that must be committed. -- `docs/generators/*.md` — auto-generated reference docs for each generator (regenerated by `bin/utils/export_docs_generators.sh`). -- `new.sh` — scaffolds a new generator (Java class + minimal template set + bin/configs entry).

Each language ships one concrete subclass (usually extending `DefaultCodegen` or a per-language `Abstract*Codegen`) under `languages/`. The class declares: - - `getName()` — the `-g` value users pass. - - `embeddedTemplateDir()` / `setTemplateDir(...)` — defaults to `modules/openapi-generator/src/main/resources//`. - - `supportingFiles` — non-per-operation files (Cargo.toml, README, etc.) added in the constructor. - - `apiTemplateFiles` / `modelTemplateFiles` — per-operation / per-model template → suffix mappings. - - CLI options registered via `cliOptions.add(new CliOption(...))`. - - Per-language data-shape overrides (`toModelName`, `toVarName`, `toEnumVarName`, `postProcessOperationsWithModels`, etc.). -3. The class is registered in `modules/openapi-generator/src/main/resources/META-INF/services/org.openapitools.codegen.CodegenConfig` (one fully-qualified class name per line). Missing this entry = generator invisible to the CLI even if compiled. -4. Mustache lookup order: `templateDir` (if user-provided via `-t`) → `embeddedTemplateDir` on the classpath. This is what makes the `-t` iteration loop work. - -### Template variables - -Templates receive `CodegenModel`, `CodegenOperation`, `CodegenParameter`, `CodegenProperty`, `CodegenResponse`, etc. Names map 1:1 to fields on those Java classes; vendor extensions surface as `vendorExtensions.x-foo`. The per-language `Abstract*Codegen` is the source of truth for naming rules — when adding behavior, prefer overriding the existing extension points there rather than rewriting raw strings in templates. - -### Tests - -- `AbstractOptionsTest` subclasses verify CLI option wiring. -- Per-generator `*CodegenTest` classes drive a fake spec through the codegen and assert on either `CodegenOperation`/`CodegenModel` fields or rendered output snippets — see `RustSalvoServerCodegenTest` for an example. -- `AllGeneratorsTest` and `ArchUnitRulesTest` enforce cross-cutting invariants (every generator must run end-to-end, package structure rules, etc.); breaking these usually means a generator class is missing a registration or a required override. - -### Adding/changing a generator - -Use `./new.sh -n -s` (server) / `-c` (client) / `-t` (also scaffold a test) — it creates the codegen class, the resources directory with the minimum templates, the `bin/configs/-petstore-new.yaml`, and updates the SPI file. Then iterate by regenerating the sample and inspecting the diff. - -## Conventions - -- Vendor extensions: lower-case-hyphen for cross-language (`x-is-unique`), `x--` for language-specific (`x-java-feign-retry-limit`). Treat them as the preferred extension point before adding a new CLI option. -- New CLI options are discouraged — prefer custom templates via `-t`. See `CONTRIBUTING.md`. -- Don't hand-edit anything under `samples/` or `docs/generators/` — both are regenerated outputs. Commit the regenerated versions alongside the source change. -- `git config core.autocrlf input` is the recommended setting; samples contain a mix of platforms. - -## rust-salvo generator status - -This fork carries an in-development `rust-salvo` server generator alongside the upstream rust-axum / rust-server / rust-server-deprecated set. State at HEAD: - -- Pinned to **Salvo 0.93** with the `oapi` / `jwt-auth` / `cors` / `serve-static` features. -- Handlers use the OpenAPI-aware `#[salvo::oapi::endpoint]` macro plus the typed extractors from `salvo::oapi::extract` (`JsonBody`, `PathParam`, `QueryParam`, `HeaderParam`, `FormBody`).

charset=UTF-8 Content-Transfer-Encoding: 8bit - Attach authentication as per-operation `.hoop(...)` on the route rather than a global service hoop, so public operations are no longer blocked by the generated middleware. - Emit one `security(("" = []))` entry per scheme on `#[salvo::oapi::endpoint]`, matching OpenAPI OR-of-requirements semantics instead of collapsing alternatives into AND. - Add `#[serde(rename = "")]` to model fields whose Rust snake_case name diverges from the OpenAPI baseName so the JSON contract is preserved (petId, photoUrls, shipDate, …). - Make `Authorization` scheme prefix matching case-insensitive in the Basic/Bearer middleware via a shared helper. - Split the HTTP-scheme middleware emission into separate `isBasicBasic` / `isBasicBearer` paths so both BasicAuth and BearerAuth structs are generated, with matching per-route factory functions. - Backfill the auth test fixture with BasicAuth and a multi-scheme (OR) operation; tighten the codegen test to cover the new factories, per-route hoops, and serde renames. - Render the README's `## API endpoints` section from `apiInfo.apis`. - Add a dedicated `build-salvo` job to `samples-rust-server.yaml` so the rust-salvo sample is covered in CI alongside rust-server / rust-axum. --- .github/workflows/samples-rust-server.yaml | 27 +++++ .../languages/RustSalvoServerCodegen.java | 108 ++++++++++++++++-- .../main/resources/rust-salvo/README.mustache | 8 +- .../src/main/resources/rust-salvo/gitignore | 1 + .../resources/rust-salvo/handlers.mustache | 4 +- .../main/resources/rust-salvo/lib.mustache | 8 +- .../resources/rust-salvo/middleware.mustache | 64 ++++++++--- .../main/resources/rust-salvo/models.mustache | 18 ++- .../main/resources/rust-salvo/routes.mustache | 11 +- .../rust/RustSalvoServerCodegenTest.java | 44 ++++++- .../3_0/rust/rust-salvo-auth-test.yaml | 34 ++++++ .../rust-salvo/output/petstore/.gitignore | 1 + .../rust-salvo/output/petstore/README.md | 29 +++++ .../output/petstore/src/handlers/pet.rs | 24 ++-- .../output/petstore/src/handlers/store.rs | 3 +- .../output/petstore/src/handlers/user.rs | 18 ++- .../rust-salvo/output/petstore/src/lib.rs | 5 +- .../output/petstore/src/middleware.rs | 38 +++++- .../rust-salvo/output/petstore/src/models.rs | 51 ++++++++- .../rust-salvo/output/petstore/src/routes.rs | 100 ++++++++++++---- 20 files changed, 509 insertions(+), 87 deletions(-) diff --git a/.github/workflows/samples-rust-server.yaml b/.github/workflows/samples-rust-server.yaml index 7530b82530d6..a450d4edf00e 100644 --- a/.github/workflows/samples-rust-server.yaml +++ b/.github/workflows/samples-rust-server.yaml @@ -5,10 +5,12 @@ on: paths: - "samples/server/petstore/rust-server/**" - "samples/server/petstore/rust-axum/**" + - "samples/server/petstore/rust-salvo/**" pull_request: paths: - "samples/server/petstore/rust-server/**" - "samples/server/petstore/rust-axum/**" + - "samples/server/petstore/rust-salvo/**" jobs: build: @@ -84,3 +86,28 @@ jobs: cargo doc popd done + + build-salvo: + name: Build Rust (salvo) + runs-on: ubuntu-latest + # The rust-salvo sample is a single crate (not the output/* multi-crate + # layout used by rust-server / rust-axum) so it gets a dedicated, simpler + # job rather than a matrix entry. + steps: + - uses: actions/checkout@v5 + - uses: actions-rs/toolchain@v1 + with: + toolchain: stable + components: rustfmt, clippy + + - name: Rust cache + uses: Swatinem/rust-cache@v2 + with: + workspaces: samples/server/petstore/rust-salvo/output/petstore + + - name: Build + working-directory: samples/server/petstore/rust-salvo/output/petstore + run: | + set -e + cargo check --all-targets + cargo clippy --all-targets diff --git a/modules/openapi-generator/src/main/java/org/openapitools/codegen/languages/RustSalvoServerCodegen.java b/modules/openapi-generator/src/main/java/org/openapitools/codegen/languages/RustSalvoServerCodegen.java index 528069b54eed..375c63f6c931 100644 --- a/modules/openapi-generator/src/main/java/org/openapitools/codegen/languages/RustSalvoServerCodegen.java +++ b/modules/openapi-generator/src/main/java/org/openapitools/codegen/languages/RustSalvoServerCodegen.java @@ -334,16 +334,13 @@ public CodegenOperation fromOperation(String path, String httpMethod, Operation op.vendorExtensions.put("x-route-path", convertPathToSalvoFormat(path));
