(#ex5vwtq) At around 19 seconds in the video, you can see some minor graphical glitches.

Text mode applications in Unix terminals are such a mess. It’s a miracle that this works at all.

In the old DOS days, you could get text (and colors) on the screen just by writing to memory, because the VGA memory was mapped to a fixed address. We don’t have that model anymore. To write a character to a certain position, you have to send an escape sequence to move the cursor to that position, then more escape sequences to set the color/attributes, then more escape sequences to get the cursor to where you actually want it. And then of course UTF-8 on top, i.e. you have no idea what the terminal will actually do when you send it a ā€œšŸ™‚ā€.

Mouse events work by the terminal sending escape sequences to you (https://www.xfree86.org/current/ctlseqs.html#Mouse%20Tracking).

ncurses does an amazing job here. It’s fast (by having off-screen buffers and tracking changes, so it rarely has to actually send full screen updates to the terminal) and reliable and works across terminals. Without the terminfo database that keeps track of which terminal supports/requires which escape sequences, we’d be lost.

But gosh, what a mess this is under the hood … Makes you really miss memory mapped VGA and mouse drivers.

(#wap76wa) @lyse@lyse.isobeef.org I haven’t spoken to a single person yet who was a fan of all this. Not even the more conservative family members.

Some people have detonated several really loud bombs yesterday. This wasn’t a ā€œBƶllerā€. It shook my walls, doors, windows. Family members in other parts of the country reported the same … Is this a new trend?


#tcz2koq

The only good thing about this absolute craziness is that I can restock my rocket sticks. I picked up twelve along the way. Unfortunately, it looks like 99.999% of ammunition is bombs instead of rockets. Some sections of my street look exactly like an arbitrary Pakistanian town that I’ve seen online.

There was surprisingly much snow in the woods. Also, all ponds have frozen over. I didn’t expect that. Not at all. There were even illegal ice skating tracks in the natural reserve. We came across a large puddle and it was at least 10cm solid ice to the ground. Crazy!

(#p43aoaq) @lyse@lyse.isobeef.org A ā€œHello Worldā€ binary is ~372KB in size. I currently have peephole optimization and deac code optimizations in play, and a few other performance related ones, but nothing too fancy. I have a test case that ensures fib(35) doesn’t regress too badly as I continue to evolve the language.


#y656lsa

Opinion / Question time…

Do you think Mu (µ)’s native compiler and therefore emitted machine code ā€œruntimeā€ (which obviously adds a bit of weight to the resulting binary, and runtime overheads) needs to support ā€œruntime stack tracesā€, or would it be enough to only support that in the bytecode VM interpreter for debuggability / quick feedback loops and instead just rely on flat (no stacktraces) errors in natively built compiled executables?

So in effect:

Stack Traces:

  • Bytecode VM Interpreter: āœ…
  • Native Code Executables: āŒ

#hagpelq

Nice! 😊 Here are the startup latencies for the simplest Mu (µ) program. println("Hello World"):

  • Interpreter: ~5ms
  • Native Code: ~1.5ms

#o4af2wq

(#2c6a7qq) @movq@www.uninformativ.de Well, just a very limited subset thereof:

  1. inline and multiline code blocks using single/double/triple backticks (but no code blocks with just indentation)
  2. markdown links using using [text](url)
  3. markdown media links using ![alt](url)

And that’s it. No bold, italics, lists, quotes, headlines, etc.

Just like mentions, plain URLs, markdown links and markdown media URLs are highlighted and available in the URLs View. They’re also colored differently, similarly to code segments.

I definitely should write some documentation and provide screenshots.


#wtcmiaa

(#2p27wba) @movq@www.uninformativ.de Yeah, I see. Just crudely checked on my computer, with around 0.013 seconds, Python 2.7 seems a tad faster than Python 3.14’s 0.023 seconds in this little program.

The lazy imports sound not too bad, but I just skimmed over them. There are surprisingly many exceptions, but yeah, no way around them. :-)


#5567spa

mu (µ) now has builtin code formatting and linting tools, making µ far more useful and useable as a general purpose programming language. Mu now includes:

  • An interpreter for quick ā€œscriptinogā€
  • A native code compiler for building native executables (Darwin / macOS only for now)
  • A builtin set of developer tools, currently: fmt (-fmt), check (-check) and test (-test).

I assume you made the thing load quickly, didn’t you?

That’s the problem with Python. If you have a couple of files to import, it will take time.

I want this to be reasonably fast on my old Intel NUC from 2016 (Celeron N3050 @ 1.60GHz) and I already notice that the program startup takes about 95 ms (or 125 ms when there are no .pyc files yet). That’s still fine, but it shows that I’ll have to be careful and keep this thing very small …

Python 3.14 will bring lazy imports, maybe that can help in some cases.


#ukhs3rq

Well, you girls and guys are making cool things, and I have some progress to show as well. šŸ˜…

https://movq.de/v/c0408a80b1/movwin.mp4

Scrolling widgets appears to work now. This is (mostly) Unicode-aware: Note how emojis like ā€œšŸ˜…ā€ are double-width ā€œcharactersā€ and the widget system knows this. It doesn’t try to place a ā€œšŸ˜…ā€ in a location where there’s only one cell available.

Same goes for that weird ā€œĆ¤ā€ thingie, which is actually ā€œaā€ followed by U+0308 (a combining diacritic). Python itself thinks of this as two ā€œcharactersā€, but they only occupy one cell on the screen. (Assuming your terminal supports this …)

This library does the heavy Unicode lifting: https://github.com/jquast/wcwidth (Take a look at its implementation to learn how horrible Unicode and human languages are.)

The program itself looks like this, it’s a proper widget hierarchy:

(There is no input handling yet, hence some things are hardwired for the moment.)


#yiihgta

I just fixed another bug in tt where the language hint in multiline markdown code blocks had not been stripped before rendering. It just looked like it was part of the actual code, which was ugly. I now throw it away. Actually, it’s already extracted into the data model for possible future syntax highlighting.


#f5crctq

(#ys4znqq) @shinyoukai@neko.laidback.moe Because you might not want to commit all changed files in a single commit. I very often make use of this and create several commits. In fact, I like to git add --patch to interactively select which parts of a file go in the next commit. This happens most likely when refactoring during a feature implementation or bug fix. I couldn’t live without that anymore. :-)

If you have a much more organized way of working where this does not come up, you can just git commit --all to include all changed files in the next commit without git adding them first. But new files still have to be git added manually once.


#u5appra

(#3hge2sq) Ok, the standard library implementation is wonky at best, at least in regards to XDG, because it really doesn’t implement it properly. https://github.com/golang/go/issues/62382 I stick to my own code then. It doesn’t properly support anything else than Linux or Unixes that use XDG, but personally, I don’t care about them anyway. And the cross-platform situation is a giant mess. Unsurprisingly.


#5dudhyq

(#iudi6qq) Hmm, mine also resolves a leading tilde in these variables. And if $HOME is not specified it tries to resolve the user’s home directory by user.Current().HomeDir. Maybe that’s overkill, I have to check the XDG spec.

But I’m definitely missing os.UserDataDir(). That’s a bummer.


#3hge2sq

(#f2cdpva) @movq@www.uninformativ.de Thanks! I’ll have a look at SnipMate. Currently, I’m (mis)using the abbreviation mechanism to expand a code snippet inplace, e.g.

autocmd FileType go inoreab <buffer> testfunc func Test(t *testing.T) {<CR>}<ESC>k0wwi

or this monstrosity:

autocmd FileType go inoreab <buffer> tabletest for _, tt := range []struct {<CR>    name string<CR><CR><BS>}{<CR>   {<CR>   name: "",<CR><BS>},<CR><BS>} {<CR>  t.Run(tt.name, func(t *testing.T) {<CR><CR>})<CR><BS>}<ESC>9ki<TAB>

But this of course has the disadvantage that I still have to remove the last space or tab to trigger the expansion by hand again. It’s a bit annoying, but better than typing it out by hand.
