* 7237Kartik Agaram2020-11-141-0/+3
| | | | | | | Minor tweaks to get Mu shell running nicely on a Linux console atop Qemu. We also need to switch a few 256-color codes to 8-color mode. I'm not sure whether/how to patch the repo for those.

* 6946 - print floats somewhat intuitively in hexKartik Agaram2020-10-041-0/+13

* 6792Kartik Agaram2020-09-161-39/+25
| | | | Roll back all buffering of Stdout.
* 6791Kartik Agaram2020-09-161-0/+8
| | | | Yeah, this isn't working.
* 6790 experiment: explicit flushKartik Agaram2020-09-161-25/+31
| | | | | | | | | tile is already visibly slow (49x212 screen) :/ So programmer needs more control over performance. But this may not be the right approach. That extra flush-stdout in tui.mu suggests it's either going to be finicky, or we have to flush on every attribute change. And going through a buffered-file may be slower. May.
* 6781 - new app: RPN (postfix) calculatorKartik Agaram2020-09-151-0/+19
| | | | This was surprisingly hard; bugs discovered all over the place.
* 6777Kartik Agaram2020-09-141-0/+31
| | | | Print answers in decimal in apps/arith.mu

* 6706 - support utf-8Kartik Agaram2020-08-021-2/+46
| | | | | | | | | | | | | | For example: fn main -> r/ebx: int { var x/eax: grapheme <- copy 0x9286e2 # code point 0x2192 in utf-8 print-grapheme-to-real-screen x print-string-to-real-screen "\n" } Graphemes must fit in 4 bytes (21 bits for code points). Unclear what we should do for longer clusters since graphemes are a fixed-size type at the moment.
* 6705Kartik Agaram2020-08-021-1/+1
| | | | Another stupid bug: I've been printing out 3 nulls for every byte of ascii.
* 6704Kartik Agaram2020-08-021-28/+28
| | | | | This is stupid; all this while I've been writing escape sequences to the screen they've been going out on stderr.
* 6703 - new types: code-point and graphemeKartik Agaram2020-08-021-2/+3
| | | | | | | | | | Both have the same size: 4 bytes. So far I've just renamed print-byte to print-grapheme, but it still behaves the same. I'm going to support printing code-points next, but grapheme 'clusters' spanning multiple code-points won't be supported for some time.
* 6699 - start building out fake screenKartik Agaram2020-08-011-29/+29
| | | | | We now have all existing apps and prototypes going through the dependency-injected wrapper, even though it doesn't actually implement the fake screen yet.
