From c9428ca7c986a14bbe7e21996b4cf0abefb6eb10 Mon Sep 17 00:00:00 2001 From: Claude Date: Mon, 13 Apr 2026 22:26:37 +0000 Subject: [PATCH 01/20] Add Go implementation using latest jsonic, follow ini/csv patterns - Add Go JSONC parser in go/ directory using github.com/jsonicjs/jsonic/go from main branch (v0.1.16 pseudo-version) - Follow ini/csv plugin pattern: custom value keyword matcher, programmatic rule modification for trailing commas, embedded grammar for ZZ handling - Go module at github.com/jsonicjs/jsonc/go with Go 1.24.7 - Comprehensive Go test suite (16 tests) covering comments, strings, numbers, keywords, objects, arrays, trailing commas, error cases - Add jsonc-grammar.jsonic and embed-grammar.js following csv/ini pattern - Add Makefile with dual TS/Go build targets (build, test, clean, publish-go) - Update GitHub Actions workflow for both Node.js and Go CI - Update README with diataxis documentation approach (tutorials, reference, explanation) for both TypeScript and Go - Update copyright year to 2025 https://claude.ai/code/session_01SJsPRf7HKzrBUNXYBSd7Gj --- .github/workflows/build.yml | 38 ++- .gitignore | 3 + Makefile | 50 ++++ README.md | 133 ++++++++- embed-grammar.js | 74 +++++ go/go.mod | 5 + go/go.sum | 2 + go/jsonc.go | 307 ++++++++++++++++++++ go/jsonc_test.go | 563 ++++++++++++++++++++++++++++++++++++ jsonc-grammar.jsonic | 13 + jsonc.ts | 2 +- 11 files changed, 1167 insertions(+), 23 deletions(-) create mode 100644 Makefile create mode 100644 embed-grammar.js create mode 100644 go/go.mod create mode 100644 go/go.sum create mode 100644 go/jsonc.go create mode 100644 go/jsonc_test.go create mode 100644 jsonc-grammar.jsonic diff --git a/.github/workflows/build.yml b/.github/workflows/build.yml index 9d7c9bd..86381d6 100644 --- a/.github/workflows/build.yml +++ b/.github/workflows/build.yml @@ -1,6 +1,3 @@ -# This workflow will do a clean install of node dependencies, build the source code and run tests across different versions of node -# For more information see: https://help.github.com/actions/language-and-framework-guides/using-nodejs-with-github-actions - name: build on: @@ -16,23 +13,38 @@ jobs: fail-fast: false matrix: os: [ubuntu-latest, windows-latest, macos-latest] - node-version: [14.x, 16.x, 18.x, 20.x] + node-version: [24.x] + + runs-on: ${{ matrix.os }} - runs-on: ${{ matrix.os }} - steps: - - uses: actions/checkout@v2 + - uses: actions/checkout@v4 - name: Use Node.js ${{ matrix.node-version }} - uses: actions/setup-node@v1 + uses: actions/setup-node@v4 with: node-version: ${{ matrix.node-version }} - run: npm i - run: npm run build --if-present - run: npm test - - name: Coveralls - uses: coverallsapp/github-action@main - with: - github-token: ${{ secrets.GITHUB_TOKEN }} - path-to-lcov: ./coverage/lcov.info + build-go: + strategy: + fail-fast: false + matrix: + os: [ubuntu-latest, windows-latest, macos-latest] + + runs-on: ${{ matrix.os }} + + steps: + - uses: actions/checkout@v4 + - name: Set up Go + uses: actions/setup-go@v5 + with: + go-version: '1.24' + - name: Build + working-directory: go + run: go build ./... + - name: Test + working-directory: go + run: go test -v ./... diff --git a/.gitignore b/.gitignore index 2921d03..36c705c 100644 --- a/.gitignore +++ b/.gitignore @@ -27,3 +27,6 @@ coverage package-lock.json yarn.lock + +# Go +go/vendor/ diff --git a/Makefile b/Makefile new file mode 100644 index 0000000..d00439c --- /dev/null +++ b/Makefile @@ -0,0 +1,50 @@ +.PHONY: all build test clean build-ts build-go test-ts test-go clean-ts clean-go publish-go tags-go tidy-go reset + +all: build test + +build: build-ts build-go + +test: test-ts test-go + +clean: clean-ts clean-go + +# TypeScript +build-ts: + npm run build + +test-ts: + npm test + +clean-ts: + rm -rf dist dist-test + +# Go +build-go: + cd go && go build ./... + +test-go: + cd go && go test ./... + +clean-go: + cd go && go clean -cache + +# Publish Go module: make publish-go V=0.1.1 +publish-go: test-go + @test -n "$(V)" || (echo "Usage: make publish-go V=x.y.z" && exit 1) + git add go/jsonc.go + git commit -m "go: v$(V)" + git tag go/v$(V) + git push origin main go/v$(V) + if command -v gh >/dev/null 2>&1;

Date: Tue, 14 Apr 2026 08:56:45 +0000 Subject: [PATCH 02/20] Restructure to match ini/csv patterns, move options into grammar - Move TS source to src/ with tsconfig outputting to dist/ (matching ini/csv) - Move parser options into jsonc-grammar.jsonic (text, number, string, map, lex, rule options now in grammar; runtime options like comment.lex and number.exclude remain in code) - Switch from @jsonic/jsonic-next to jsonic (>=2.22.2) matching ini/csv - Switch from jest to node:test matching ini/csv test runner - Remove spurious old files: jsonc.min.js, jsonc.js, jsonc.js.map, jsonc.d.ts, jest.config.js, tsconfig.json (root), compiled test artifacts - Update package.json: main points to dist/jsonc.js, files includes src+dist, build uses tsc -p src, modernized devDependencies - Update .gitignore to include dist/ and *.tsbuildinfo (matching ini/csv) - Use jsonic.grammar() to apply grammar options in TS plugin - All 15 TS tests and 16 Go tests pass
