Automatic compilation #15

Open alfonsogarciacaro opened 6 years ago

alfonsogarciacaro commented 6 years ago

There's a problem now: the F# code is parsed every second, so when you press Alt+enter you may get old code. I was thinking about how to solve this but my conclusion was that, given we're already parsing the code every second (we can make it 2-3s to improve performance), we should compile it directly so the user doesn't even need to hit the Compile button. Together with moving the FSharpChecker to a worker, this should improve the user experience.

I can take care of this :+1:

2-3s can feel slow to get the intellisense no ?

And yes, we need to move the FSharpChecker to a worker because it's freezing the UI. We could also force to parse the editor like we do when loading an example example

Intellisense will still be fast but error checking will take a bit longer. I think that's a fair price to pay to prevent the UI from freezing. You can try it out just by incrementing the number of milliseconds in this line.
