Version 1.0.46

Environment Variable Expansion in MCP Server Configuration

• Added support for environment variable expansion in MCP server configurations using ${VAR} syntax
• Supports default values with ${VAR:-default} notation
• Validates that all required environment variables are set before starting servers
• Example usage in MCP config:

  {
    "mcpServers": {
      "myServer": {
        "command": "${HOME}/bin/server",
        "args": ["--port", "${PORT:-8080}"],
        "env": {
          "API_KEY": "${MY_API_KEY}"
        }
      }
    }
  }

Background Command Execution Shortcut

• Added keyboard shortcut Ctrl+B to run long-running commands in the background
• Displays helpful hint "Ctrl+B to run in background" when commands are executing
• Allows users to quickly background tasks without waiting for the command selection dialog

Enhanced Long-Running Command Display

• Improved the display of long-running commands to show the last 2 lines of output
• Shows line count indicator (e.g., "+15 more lines") for truncated output
• More compact and informative display during command execution

WSL Path Translation Support

• Added automatic path translation between Windows and WSL environments
• New ie class handles bidirectional path conversion:
• toLocalPath(): Converts Windows paths to WSL paths
• toIDEPath(): Converts WSL paths to Windows paths
• Automatically detects and handles WSL distribution names in paths

Circular Buffer for Command Output

• Implemented qu1 circular buffer class for efficient handling of streaming command output
• Maintains only the most recent output lines in memory
• Reduces memory usage for long-running commands with extensive output

Tool Result Compaction

• Added intelligent compaction for frequently-used tool outputs to reduce token usage
• Compacts results for: Read, Edit, MultiEdit, Write, Bash, Grep, Glob, LS, WebSearch, WebFetch
• Preserves essential information while reducing verbosity
• Example: [Read /path/to/file.js, details compacted] instead of full file contents

Installation Health Check Improvements

• Fixed auto-update detection for global npm installations
• Removed check for global installations being unable to auto-update (no longer applicable)
• Improved permission checking for update capabilities

Shell Execution Error Handling

• Added try-catch block around shell command spawning to handle execution failures gracefully
• Returns proper error response with exit code 126 when shell command fails to start
• Provides clear error messages in stderr when execution fails

Updated Dependencies

• Removed redundant stream imports (stream and node:stream)
• Added new imports for child process operations from specific modules
• Updated to use PassThrough from node:stream consistently

Code Organization

• Removed 39 unused functions and variables, including:
• String trimming utilities (um2, dm2)
• Number parsing functions (am2, sm2, om2)
• Array shuffling functions (na2, aa2, ra2)
• Unused configuration functions
• Added 30 new functions focused on MCP support and improved command handling

Configuration Constants

• Added lw6 = 2000 for command output line limits
• Added WS6 = 2000 for WebSearch result limits
• Added F$6 = 80000 for maximum tool output size
• Added zQA = 3 for retry attempts

• The codebase now includes better support for development environments with proper __dirname handling
• Git status information is now truncated at 40,000 characters to prevent overwhelming the context
• Improved modularity with separate concerns for path translation, environment expansion, and output buffering
