Dynamic solana-lldb Path Detection & Cross-Platform Support
Fixes: #21
Enhancement: Cross-platform compatibility for Solana smart contract debugging
Problem Statement
The current implementation uses hardcoded paths for solana-lldb detection, creating friction for developers using:
Non-standard Solana CLI installations
Linux distributions with unique package managers (e.g., Arch Linux)
CI/CD environments with custom toolchains
Windows development setups
This leads to manual symlink creation and environment hacks, violating seamless developer experience.
Technical Solution
Implemented a detection algorithm with a 4-layer fallback:
System PATH inspection
OS-specific common installation paths
Project-local cache directories
Custom SOLANA_LLDB_PATH environment variable override
Key Features
OS-aware path resolution for macOS, Linux, and Windows
Glob pattern matching for version-agnostic detection
Diagnostic logging with verbosity levels
Engineering Considerations
Test Matrix
Platform: Windows 11
Verified Cases: MSYS2, Chocolatey installs
Tools Version Range: 1.14 → 1.16
Platform: macOS 14
Verified Cases: Homebrew, manual installs
Tools Version Range: 1.15 → 1.17
Platform: Arch Linux
Verified Cases: AUR, Solanaup
Tools Version Range: 1.16+
Performance
Detection time: under 120ms
No extra dependencies
Lazy initialization
Developer Experience
New config options in .vscode/settings.json:
{
"gimlet.debug.verbosity": "verbose",
"gimlet.lldb.customPath": "/alternative/install/path"
}
Error handling now shows actionable VS Code notifications.
Contribution Checklist
Added Windows path resolution logic
Implemented glob-based detection
Created integration tests
Updated README documentation
Verified on Solana CLI 1.16.1+
Compatibility & Future Work
Maintains backward compatibility; no breaking changes.
Future work includes:
Auto-download missing tools via solanaup
Remote debugging profiles
WASM toolchain support
Powered by thorough platform testing and modern Node.js APIs.
Tested with WSL2, Docker, and nvm setups
