Spent basically the entire day (except for the mandatory walk) fighting with Python’s type hints. But, the result is that my widget toolkit now passes mypy --strict.

I really, really don’t want to write larger pieces of software without static typing anymore. With dynamic typing, you must test every code path in your program to catch even the most basic errors. pylint helps a bit (doesn’t need type hints), but that’s really not enough.

Also, somewhere along the way, I picked up a very bad (Python) programming style. (Actually, I know exactly where I picked that up, but I don’t want to point the finger now.) This style makes heavy use of dicts and tuples instead of proper classes. That works for small scripts, but it very quickly turns into an absolute mess once the program grows. Prime example: jenny. 😩

I have a love-hate relationship with Python’s type hints, because they are meaningless at runtime, so they can be utterly misleading. I’m beginning to like them as an additional safety-net, though.

(But really, if correctness is the goal, you either need to invest a ton of time to get 100% test coverage – or don’t use Python.)

yes, yes that’s right. Mu (µ) now has a built-in LSP server for fans of VS Code / VSCodium 😅 You just go install ./cmd/mu-lsp/... and install the VS extension and hey presto 🥳 You get outlines of any Mu source, Find References and Go to Definition!

@prologic@twtxt.net I’d love to take a look at the code. 😅

I’m kind of curious to know how much Assembly I need vs. How much of a microkernel can I build purely in Mu (µ)? 🤔

Can’t really answer that, because I only made a working kernel for 16-bit real mode yet. That is 99% C, though, only syscall entry points are Assembly. (The OpenWatcom compiler provides C wrappers for triggering software interrupts, which makes things easier.)

But in long mode? No idea yet. 😅 At least changing the page tables will require a tiny little bit of Assembly.

I’m trying to implement configurable key bindings in tt. Boy, is parsing the key names into tcell.EventKeys a horrible thing. This type consists of three information:

1. maybe a predefined compound key sequence, like Ctrl+A
   
2. maybe some modifiers, such as Shift, Ctrl, etc.
   
3. maybe a rune if neither modifiers are present nor a predefined compound key exists
   

It’s hardcoded usage results in code like this:

func (t *TreeView[T]) InputHandler() func(event *tcell.EventKey, setFocus func(p tview.Primitive)) {
    return t.WrapInputHandler(func(event *tcell.EventKey, setFocus func(p tview.Primitive)) {
        switch event.Key() {
        case tcell.KeyUp:
            t.moveUp()
        case tcell.KeyDown:
            t.moveDown()
        case tcell.KeyHome:
            t.moveTop()
        case tcell.KeyEnd:
            t.moveBottom()
        case tcell.KeyCtrlE:
            t.moveScrollOffsetDown()
        case tcell.KeyCtrlY:
            t.moveScrollOffsetUp()
        case tcell.KeyTab, tcell.KeyBacktab:
            if t.finished != nil {
                t.finished(event.Key())
            }
        case tcell.KeyRune:
            if event.Modifiers() == tcell.ModNone {
                switch event.Rune() {
                case 'k':
                    t.moveUp()
                case 'j':
                    t.moveDown()
                case 'g':
                    t.moveTop()
                case 'G':
                    t.moveBottom()
                }
            }
        }
    })
}

This data structure is just awful to handle and especially initialize in my opinion. Some compound tcell.Keys are mapped to human-readable names in tcell.KeyNames. However, these names always use - to join modifiers, e.g. resulting in Ctrl-A, whereas tcell.EventKey.Name() produces +-delimited strings, e.g. Ctrl+A. Gnaarf, why this asymmetry!? O_o

I just checked k9s and they’re extending tcell.KeyNames with their own tcell.Key definitions like crazy: https://github.com/derailed/k9s/blob/master/internal/ui/key.go Then, they convert an original tcell.EventKey to tcell.Key: https://github.com/derailed/k9s/blob/b53f3091ca2d9ab963913b0d5e59376aea3f3e51/internal/ui/app.go#L287 This must be used when actually handling keyboard input: https://github.com/derailed/k9s/blob/e55083ba271eed6fc4014674890f70c5ed6c70e0/internal/ui/tree.go#L101

This seems to be much nicer to use. However, I fear this will break eventually. And it’s more fragile in general, because it’s rather easy to forget the conversion or one can get confused whether a certain key at hand is now an original tcell.Key coming from the library or an “extended” one.

I will see if I can find some other programs that provide configurable tcell key bindings.
