Baremetal is now the default build target and therefore has its sources
at the top-level. Baremetal programs build using the phase-2 Mu toolchain
that requires a Linux kernel. This phase-2 codebase which used to be at
the top-level is now under the linux/ directory. Finally, the phase-2 toolchain,
while self-hosting, has a way to bootstrap from a C implementation, which
is now stored in linux/bootstrap. The bootstrap C implementation uses some
literate programming tools that are now in linux/bootstrap/tools.
So the whole thing has gotten inverted. Each directory should build one
artifact and include the main sources (along with standard library). Tools
used for building it are relegated to sub-directories, even though those
tools are often useful in their own right, and have had lots of interesting
programs written using them.
A couple of things have gotten dropped in this process:
- I had old ways to run on just a Linux kernel, or with a Soso kernel.
No more.
- I had some old tooling for running a single test at the cursor. I haven't
used that lately. Maybe I'll bring it back one day.
The reorg isn't done yet. Still to do:
- redo documentation everywhere. All the README files, all other markdown,
particularly vocabulary.md.
- clean up how-to-run comments at the start of programs everywhere
- rethink what to do with the html/ directory. Do we even want to keep
supporting it?
In spite of these shortcomings, all the scripts at the top-level, linux/
and linux/bootstrap are working. The names of the scripts also feel reasonable.
This is a good milestone to take stock at.

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.

Roll back all buffering of Stdout.

Yeah, this isn't working.

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.

This was surprisingly hard; bugs discovered all over the place.

Print answers in decimal in apps/arith.mu

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.

Another stupid bug: I've been printing out 3 nulls for every byte of ascii.
|
| |
|
|
|
| |
This is stupid; all this while I've been writing escape sequences to the
screen they've been going out on stderr.
|
| |
|
|
|
|
|
|
|
|
| |
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.

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.
