I just memeory leak and gain infinite performance /s

Does not look as nice, but is way less misleading

Isn’t the second if condition false?

I have a custom split keyboard (lily58) and use the neo special character layer as my lower layer

But only if you don’t look

Sounds good,

but would the preferred way be to use a wrapper type, which holds either the data or the error and avoid exceptions completely?

I’m currently learning functional languages and have only limited knowledge, but from what I’ve read now you are right. Throwing exceptions is pure, but catching them is impure.

In this case I guess the printLine function can throw an exception therefore the calling function must be declared with Exception?

Yes, in functional programming you want to use pure functions. Exceptions are impure, therefore it has to be declared.

Other functional languages don’t even have exceptions

There are no imports, these are type annotations

I would remove the keybinding Ctrl + Alt + T for opening the terminal in the README for distros like Arch and Gentoo.

It depends on the installed DE/WM and can be incorrect depending on the users config

if (theorems_for(free))
    make_instance_of(x, String)

Please put your code between tripple backticks in a seperate line above an below your code. Single backticks are only for inline code like this.

To answer your question, the %.2f means it should only print two digits after the decimal point.

You can also use some other variations like this:

• %2f print the number at least 2 characters wide
• %5.2 print the number at least 5 characters wide with a precision of two digits after the decimal point
• %05.2 the same as above, but fill leading digits with zeros

This is just formatting, play a bit around with it and you will get it.

Graphene just changed it to be enabled by default

But maybe they hat this feature earlier than AOSP
