From 8fad98ffdbe9b157c4635fd943732f29d9d4de68 Mon Sep 17 00:00:00 2001 From: Dylan Conway Date: Sat, 23 Aug 2025 06:55:30 -0700 Subject: [PATCH] Add `Bun.YAML.parse` and YAML imports (#22073) ### What does this PR do? This PR adds builtin YAML parsing with `Bun.YAML.parse` ```js import { YAML } from "bun"; const items = YAML.parse("- item1"); console.log(items); // [ "item1" ] ``` Also YAML imports work just like JSON and TOML imports ```js import pkg from "./package.yaml" console.log({ pkg }); // { pkg: { name: "pkg", version: "1.1.1" } } ``` ### How did you verify your code works? Added some tests for YAML imports and parsed values. --------- Co-authored-by: Claude Bot Co-authored-by: Claude Co-authored-by: autofix-ci[bot] <114827586+autofix-ci[bot]@users.noreply.github.com> Co-authored-by: Jarred Sumner --- bench/yaml/bun.lock | 19 + bench/yaml/package.json | 8 + bench/yaml/yaml-parse.mjs | 368 ++ cmake/sources/CxxSources.txt | 1 + cmake/sources/ZigSources.txt | 3 + docs/api/yaml.md | 530 ++ docs/bundler/executables.md | 41 +- docs/nav.ts | 3 + .../bundler_plugin.h | 4 +- packages/bun-types/extensions.d.ts | 10 + src/StandaloneModuleGraph.zig | 20 +- src/analytics.zig | 1 + src/api/schema.d.ts | 74 +- src/api/schema.js | 122 +- src/api/schema.zig | 36 +- src/bake/DevServer/DirectoryWatchStore.zig | 1 + src/bun.js/ConsoleObject.zig | 2 +- src/bun.js/ModuleLoader.zig | 6 +- src/bun.js/api.zig | 1 + src/bun.js/api/BunObject.zig | 7 + src/bun.js/api/YAMLObject.zig | 158 + src/bun.js/api/bun/subprocess.zig | 3 +- src/bun.js/bindings/BunObject+exports.h | 1 + src/bun.js/bindings/BunObject.cpp | 1 + src/bun.js/bindings/JSGlobalObject.zig | 3 +- src/bun.js/bindings/MarkedArgumentBuffer.zig | 16 + .../bindings/MarkedArgumentBufferBinding.cpp | 15 + src/bun.js/bindings/ModuleLoader.cpp | 4 +- src/bun.js/bindings/ZigString.zig | 22 - .../bindings/generated_perf_trace_events.h | 80 +- src/bun.js/bindings/headers-handwritten.h | 9 +- src/bun.js/jsc.zig | 1 + src/bundler/LinkerContext.zig | 2 +- src/bundler/ParseTask.zig | 12 + src/bundler/bundle_v2.zig | 5 +- src/generated_perf_trace_events.zig | 2 +- src/http/MimeType.zig | 2 + src/interchange.zig | 1 + src/interchange/yaml.zig | 5468 +++++++++++++++++ src/js_printer.zig | 1 + src/options.zig | 66 +- src/string/immutable/unicode.zig | 2 +- src/transpiler.zig | 7 +- src/windows.zig | 21 +- test/bundler/bundler_loader.test.ts | 11 + test/bundler/compile-windows-metadata.test.ts | 271 +- test/internal/ban-limits.json | 2 +- test/js/bun/bundler/yaml-bundler.test.js | 60 + .../import-attributes.test.ts | 72 +- test/js/bun/resolve/import-empty.test.js | 2 +- test/js/bun/resolve/yaml/yaml-empty.yaml | 1 + test/js/bun/resolve/yaml/yaml-fixture.yaml | 16 + .../js/bun/resolve/yaml/yaml-fixture.yaml.txt | 4 + test/js/bun/resolve/yaml/yaml-fixture.yml | 4 + test/js/bun/resolve/yaml/yaml.test.js | 69 + test/js/bun/yaml/yaml.test.ts | 337 + 56 files changed, 7617 insertions(+), 391 deletions(-) create mode 100644 bench/yaml/bun.lock create mode 100644 bench/yaml/package.json create mode 100644 bench/yaml/yaml-parse.mjs create mode 100644 docs/api/yaml.md create mode 100644 src/bun.js/api/YAMLObject.zig create mode 100644 src/bun.js/bindings/MarkedArgumentBuffer.zig create mode 100644 src/bun.js/bindings/MarkedArgumentBufferBinding.cpp create mode 100644 src/interchange/yaml.zig create mode 100644 test/js/bun/bundler/yaml-bundler.test.js create mode 100644 test/js/bun/resolve/yaml/yaml-empty.yaml create mode 100644 test/js/bun/resolve/yaml/yaml-fixture.yaml create mode 100644 test/js/bun/resolve/yaml/yaml-fixture.yaml.txt create mode 100644 test/js/bun/resolve/yaml/yaml-fixture.yml create mode 100644 test/js/bun/resolve/yaml/yaml.test.js create mode 100644 test/js/bun/yaml/yaml.test.ts diff --git a/bench/yaml/bun.lock b/bench/yaml/bun.lock new file mode 100644 index 0000000000..e29d63fa07 --- /dev/null +++ b/bench/yaml/bun.lock @@ -0,0 +1,19 @@ +{ + "lockfileVersion": 1, + "workspaces": { + "": { + "name": "yaml-benchmark", + "dependencies": { + "js-yaml": "^4.1.0", + "yaml": "^2.8.1", + }, + }, + }, + "packages": { + "argparse": ["argparse@2.0.1", "", {}, "sha512-8+9WqebbFzpX9OR+Wa6O29asIogeRMzcGtAINdpMHHyAg10f05aSFVBbcEqGf/PXw1EjAZ+q2/bEBg3DvurK3Q=="], + + "js-yaml": ["js-yaml@4.1.0", "", { "dependencies": { "argparse": "^2.0.1" }, "bin": { "js-yaml": "bin/js-yaml.js" } }, "sha512-wpxZs9NoxZaJESJGIZTyDEaYpl0FKSA+FB9aJiyemKhMwkxQg63h4T1KJgUGHpTqPDNRcmmYLugrRjJlBtWvRA=="], + + "yaml": ["yaml@2.8.1", "", { "bin": { "yaml": "bin.mjs" } }, "sha512-lcYcMxX2PO9XMGvAJkJ3OsNMw+/7FKes7/hgerGUYWIoWu5j/+YQqcZr5JnPZWzOsEBgMbSbiSTn/dv/69Mkpw=="], + } +} diff --git a/bench/yaml/package.json b/bench/yaml/package.json new file mode 100644 index 0000000000..b088fb1dd5 --- /dev/null +++ b/bench/yaml/package.json @@ -0,0 +1,8 @@ +{ + "name": "yaml-benchmark", + "version": "1.0.0", + "dependencies": { + "js-yaml": "^4.1.0", + "yaml": "^2.8.1" + } +} \ No newline at end of file diff --git a/bench/yaml/yaml-parse.mjs b/bench/yaml/yaml-parse.mjs new file mode 100644 index 0000000000..7cb4a8a619 --- /dev/null +++ b/bench/yaml/yaml-parse.mjs @@ -0,0 +1,368 @@ +import { bench, group, run } from "../runner.mjs";
