## 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.
