Solstice is a VSCode extension for Solidity that adds debugging and execution tracing capabilities. It lets you trace and debug the execution of Solidity tests directly in your editor. The extension provides real-time visualization of contract state, memory, storage, and execution flow, making it easier to understand and troubleshoot smart contract behavior.
The language support in Solstice is forked from the Solang VSCode extension. This fork maintains all the language features from Solang while adding specialized debugging tools. Long-term, the plan is to migrate to the Solar parser library when it's production ready.
Build the Rust server:
$ cargo build
Build the VSCode extension:
$ npm run compile
Open Solstice in Vscode and Open the Run and Debug tab. Execute the Launch Client configuration and open any Solidity project.
