Flix comes with a fully-featured Visual Studio Code Extension:
The Flix extension uses the real Flix compiler hence all information (e.g. error messages) are always 1:1 with the real Flix programming language.
Flix also comes with an (optional) Visual Studio Code color theme called "Flixify Dark".
Semantic Syntax Highlighting
- Code highlighting for *.flix files. This work best with the official vscode theme.
- Compiler error messages.
- Auto-complete as you type.
- Auto-completion is context aware.
- Type-directed completion of program holes.
- Auto-complete common code constructs.
- Shows inline type information.
Type and Effect Hovers
- Hover over any expression to see its type and effect.
- Hover over any local variable or formal parameter to see its type.
- Hover over any function to see its type signature and documentation.
Jump to Definition
- Jump to the definition of any function.
- Jump to the definition of any local variable or formal parameter.
- Jump to the definition of any enum case.
- Find all references to a function.
- Find all references to a local variable or formal parameter.
- Find all references to an enum case.
- Find all implementations of a trait.
- List all document symbols.
- List all workspace symbols.
- Rename local variables or formal parameters.
- Rename functions.
mainfrom within the editor.
- Run tests from within the editor.
- Highlights semantically related symbols.
- Additional code highlighting hints provided by the compiler.
There is a known issue with PowerShell and using file names that contain special characters. We recommend that Flix source files are given only ASCII names.
The extension assumes that you are working in "Workspace Mode", i.e. you must have a folder open which contains your Flix source code.
Upon startup, the Flix compiler has to load the entire Flix standard library into its caches which takes a few seconds.
