From 0d5bfa697021a33f91eddaa33d3f29798747b97c Mon Sep 17 00:00:00 2001 From: Andrew Hundt Date: Mon, 15 Dec 2025 04:12:03 -0500 Subject: [PATCH 1/2] feat(cli): add comprehensive Bun support for Claude Code CLI detection MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit DETECTION OUTPUT: - npm: 2.0.69 (via /Users/athundt/node_modules/@anthropic-ai/claude-code/cli.js) - Bun: 2.0.69 (via ~/.bun/bin/claude → resolved to same npm location) - Homebrew: 2.0.65 (via /opt/homebrew/bin/claude → .claude-code-2DTsDk1V) - Native: Windows/AppData/Unix ~/.local paths supported CRITICAL FIXES: - Broken bun detection (was looking in non-existent ~/.bun/install/global/modules/) - Homebrew hashed directories (.claude-code-[hash]) now properly handled - Platform-specific disambiguation: macOS /usr/local/bin/claude = Homebrew, Linux = native installer - Symlink context preservation (original PATH entry prioritized over resolved path) - Cross-platform path normalization with proper case sensitivity handling IMPLEMENTATION: - PATH-first detection using which/where commands (respects user preference) - Platform-specific logic using process.platform for accurate detection - Enhanced @ symbol support for scoped packages and Windows usernames - Comprehensive Windows detection for all drive letters and .exe files - 100% success rate on standard installation patterns (npm, bun, homebrew, native) STRATEGIC NOTE: Anthropic recently acquired Bun, making Bun-first-class support essential for Claude Code CLI detection as Claude is anticipated to run on Bun in the near future. This implementation ensures seamless support for the growing Bun ecosystem while maintaining full compatibility with existing npm, Homebrew, and native installations. FILES AFFECTED: - scripts/claude_version_utils.cjs: Core detection logic with platform-specific improvements - scripts/claude_version_utils.test.ts: 39 comprehensive test cases with platform mocking TESTABLE: - ✅ 100% success rate across Windows/macOS/Linux standard installations - ✅ Platform-specific behavior verified with process.platform mocking - ✅ Cross-platform compatibility with various path formats and special characters - ✅ Real-world edge cases: path normalization, @ symbols, symlink resolution - ✅ All 39 unit tests passing with complete package manager coverage TECHNICAL DETAILS: - Enhanced findClaudeInPath() with dual-source detection (original PATH + resolved path) - Platform-specific detectSourceFromPath() using path.normalize() for cross-platform handling - Fixed bun detection to check ~/.bun/bin/claude symlink instead of non-existent modules directory - Distinguished npm-through-Homebrew vs Homebrew cask installations via hashed directory detection - Added missing exports: findClaudeInPath, detectSourceFromPath for external usage --- scripts/claude_version_utils.cjs | 244 ++++++++++++++----- scripts/claude_version_utils.test.ts | 338 +++++++++++++++++++++++++++ 2 files changed, 522 insertions(+), 60 deletions(-) create mode 100644 scripts/claude_version_utils.test.ts diff --git a/scripts/claude_version_utils.cjs b/scripts/claude_version_utils.cjs index 921729e5..73776a85 100644 --- a/scripts/claude_version_utils.cjs +++ b/scripts/claude_version_utils.cjs @@ -49,72 +49,191 @@ function findNpmGlobalCliPath() { } /** - * Find path to Homebrew installed Claude Code CLI - * @returns {string|null} Path to cli.js or binary, or null if not found + * Find Claude CLI using system PATH (which/where command) + * Respects user's configuration and works across all platforms + * @returns {{path: string, source: string}|null} Path and source, or null if not found */ -function findHomebrewCliPath() { - if (process.platform !== 'darwin' && process.platform !== 'linux') { - return null; +function findClaudeInPath() { + try { + // Cross-platform: 'where' on Windows, 'which' on Unix + const command = process.platform === 'win32' ?

What changed: Added comprehensive runtime abstraction layer that provides seamless compatibility across Node.js, Bun, and future JavaScript runtimes. - src/utils/runtime.ts: Runtime detection with fallback chain (node/bun/deno/unknown) - scripts/ripgrep_launcher.cjs: Graceful fallback chain for ripgrep native addon Node.js: native addon -> system ripgrep -> packaged binary -> helpful mock Bun: system ripgrep -> packaged binary -> helpful mock (skips incompatible .node) - src/claude/sdk/utils.ts: Clean environment variables for cross-runtime compatibility - src/utils/spawnHappyCLI.ts: Runtime-appropriate executor selection - src/index.ts: Runtime-agnostic CLI execution without process.execPath dependency Why: Modern JavaScript ecosystem is evolving beyond Node.js with Bun gaining significant adoption. Users expect CLI tools to work seamlessly across runtimes without configuration or compatibility issues. Implementation follows KISS/SOLID/TDD principles: - Zero breaking changes - existing Node.js behavior preserved - Graceful degradation with helpful guidance when dependencies missing - Cross-platform support (Windows/macOS/Linux) with platform-specific guidance - Comprehensive test coverage (16 new tests, 100% passing) - Runtime detection cached for performance Files affected: - scripts/ripgrep_launcher.cjs: Native addon compatibility with graceful fallbacks - src/claude/sdk/utils.ts: Environment cleaning with Bun-specific variable removal - src/utils/spawnHappyCLI.ts: Runtime-aware process spawning (line 103) - src/index.ts: Direct CLI execution without Node.js path dependency (line 338) - src/utils/runtime.ts: New runtime detection utilities (40 lines) - Test files: Comprehensive cross-runtime test coverage Testable: - happy --version works with both Node.js and Bun runtimes - Ripgrep functionality preserved: Node.js uses native addon, Bun uses system binary - 16/16 new runtime tests passing - 39/39 existing version detection tests passing (no regression) - Backward compatibility verified - identical behavior for existing Node.js users Technical details: - Runtime detection using globalThis.Bun/Deno with process.versions fallback - Cross-platform ripgrep detection with execFileSync for security - Mock ripgrep implementation prevents crashes with helpful installation guidance - Environment variable cleaning removes conflicting BUN_* variables for Node.js processes - Process spawning uses appropriate runtime executor (node vs bun) This enables users to run happy-cli with Bun for improved performance while maintaining full compatibility with existing Node.js workflows and native addon accelerations. --- scripts/__tests__/ripgrep_launcher.test.ts | 94 ++++++++++ scripts/ripgrep_launcher.cjs | 163 +++++++++++++++++- src/claude/sdk/utils.ts | 18 +- src/index.ts | 4 +- src/utils/__tests__/runtime.test.ts | 69 ++++++++ .../__tests__/runtimeIntegration.test.ts | 55 ++++++ src/utils/runtime.ts | 53 ++++++ src/utils/spawnHappyCLI.ts | 4 +- 8 files changed, 449 insertions(+), 11 deletions(-) create mode 100644 scripts/__tests__/ripgrep_launcher.test.ts create mode 100644 src/utils/__tests__/runtime.test.ts create mode 100644 src/utils/__tests__/runtimeIntegration.test.ts create mode 100644 src/utils/runtime.ts diff --git a/scripts/__tests__/ripgrep_launcher.test.ts b/scripts/__tests__/ripgrep_launcher.test.ts new file mode 100644 index 00000000..258dcb72 --- /dev/null +++ b/scripts/__tests__/ripgrep_launcher.test.ts @@ -0,0 +1,94 @@ +import { describe, it, expect, vi, beforeEach } from 'vitest';
