fls brings LSP-powered editor features to Flint development
Experience LSP-powered editor features: real-time diagnostics, IntelliSense, and go-to-definition while you edit Flint code. Flint Organisation supplies the server as part of the Flint toolchain, integrating with text editors that support the Language Server Protocol. Key editor capabilities include syntax highlighting, code completion, and on-the-fly warning reporting to surface issues during authoring. The tool fits Flint developers and systems engineers who want IDE-like assistance inside their existing editor without switching compilers during edit time.
What does fls do for Flint code editing?
fls (Flint Language Server) implements the Language Server Protocol to present editor features usually found in IDEs. It supplies syntax highlighting, formatting, and intelligent code completion for functions, variables, and keywords, plus go-to-definition and symbol search. These services run inside any LSP-compatible editor, which means the editor displays diagnostics and suggestions while you type rather than waiting for a separate compiler run.
Does fls affect system resources or development workflow?
fls is described as lightweight and designed for high-performance language analysis, so it can run alongside an editor without heavy resource use. Because it communicates via LSP, the server processes requests incrementally and reports diagnostics on the fly; that interaction reduces the need for frequent full-project recompiles during editing. The server is available as a Windows executable (fls.exe) and also supports Linux and macOS environments.
Is fls safe to run and how does it interact with the Flint compiler?
The server interoperates with the Flint compiler ecosystem but does not replace the compiler: you still need the Flint compiler to build and run code. fls focuses on read-only analysis of source for diagnostics and completions, which aligns with the language's DIMA memory model support. Because it provides editor-side intelligence rather than build-time code generation, it does not perform write operations on build artifacts.
Appropriate for Flint developers who need editor integration, not a build tool
fls serves developers who want live language analysis inside their editor, offering diagnostics and navigation tied to the Flint language model. It is not a compiler and must be used alongside the Flint compiler for builds and runs. For anyone writing Flint code inside an LSP-capable editor, fls provides essential editor services while leaving compilation and execution to the compiler component of the toolchain.
