# BF extension
A simple language server based VSCode Extension for the (Branflakes?) (BrainFuck?) BF language. You can also execute your code and see its output.

## Functionality
- Syntax Highlighting
- Execution
- Autocomplete suggestions
### Execution
Use the BF execute task to execute the code.
Either run the "current file" task, or create a customized task with the required file.
I/O is done on the created terminal window.
There is also an older command to run the code, where output is shown as a status message. Here, if the program requires input, it will be requested as a prompt.
