charset=UTF-8 Content-Transfer-Encoding: 8bit This commit addresses the issue where JSON strings containing quotes and special characters get corrupted when passed through command-stream's shell interpolation. ### Key Changes: 1. **Enhanced Shell Operator Detection** - Added detection for redirection operators (`>`, `>>`, `<`, `2>`, etc.) in hasShellOperators to properly identify when commands need real shell execution 2. **Improved needsRealShell Function** - Added basic redirection operators to the unsupported features list, forcing JSON commands with redirection to use real shell instead of virtual commands 3. **Virtual Command Bypass** - Added needsRealShell check to virtual command decision logic to prevent JSON strings with redirection from being processed by virtual echo command 4. **Version Bump** - Updated to 0.7.2 ### Test Cases Added: - Comprehensive JSON escaping test suite - Examples demonstrating proper JSON usage with shell redirection ### Impact: - ✅ JSON strings with nested quotes now work correctly with shell redirection - ✅ Special characters (backticks, dollar signs) are properly preserved - ✅ All existing functionality maintained (no regressions) - ✅ Fixes configuration management, API integration, and build script use cases Example working usage: ```javascript const jsonData = { name: "test", description: "with 'quotes' and \"double quotes\"" }; await $`echo ${JSON.stringify(jsonData)} > config.json`; // Now works correctly! ``` 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- examples/test-proper-json-usage.mjs | 75 ++++++++++++++++++ package.json | 2 +- src/$.mjs | 11 ++- src/shell-parser.mjs | 3 + tests/json-escaping.test.mjs | 115 ++++++++++++++++++++++++++++ 5 files changed, 204 insertions(+), 2 deletions(-) create mode 100755 examples/test-proper-json-usage.mjs create mode 100644 tests/json-escaping.test.mjs diff --git a/examples/test-proper-json-usage.mjs b/examples/test-proper-json-usage.mjs new file mode 100755 index 0000000..204d118 --- /dev/null +++ b/examples/test-proper-json-usage.mjs @@ -0,0 +1,75 @@ +#!/usr/bin/env node +import { $ } from '../src/$.mjs';
