Mew's build system "Purr" is coming along nicely. It's still an early prototype, but everything finally works the way I envisioned! Naturally, it's written in Mew and included in the stdlib.

Terminal output from the Mew build system. The first run executes three steps (setup, restore, compile) and finishes in 2.4 seconds. Running the same "mew run build.mew compile" command again skips restore and compile because they're already up to date, and the build finishes in 0.0 seconds.

A Mew build script:

```
task restore
in sources = glob(
"src/compiler/**/*.{csproj,props}",
"global.json")
out assets = glob("src/compiler/**/obj/project.assets.json") {
dotnet("restore", "src/compiler/Mew.slnx")?;
}

task compile(ctx: Mew) : restore
in sources = glob(
"src/compiler/**/*.{cs,csproj,props,targets}",
"src/stdlib/lib/**/*.mew",
"global.json",
"!**/{obj,bin}/**")
out compiler = file($"src/compiler/Mew/bin/{ctx.configuration()}/net10.0/Mew.dll")
{
dotnet("build", "src/compiler/Mew.slnx", "--no-restore", "-c", ctx.configuration())?;
}
```

My long-standing dream finally came true! A visualization of a dependency DAG drawing arrows without intersections. Each selected figure depends on a couple of figures before it in the topological sort order. This way you can see the closure of all dependencies for any figure.

Screenshot of the Live Geometry app. On the right, triangle ABC is shaded light blue and has yellow vertices. A thick blue circle passes through all three vertices. Gray midpoints D (on side BC) and E (on side AB) each have a perpendicular gray line with a small right-angle mark. The two lines cross at the circle's center, a cyan point labeled O.

On the left, a panel titled "Figures" lists everything in the construction in order, each with a small icon: Points A, B, C and D, Segment BC, PerpendicularLine13, Point E, Segment AB, PerpendicularLine15, Point O, Circle, Segment AC and Triangle ABC. Gray arrows in the margin connect each figure to the figures it was built from. "Circle" is selected, and blue arrows from it point to Point O and Point B, its center and a point on it.

strangely, @davidfowl.com and NuPack make an appearance in 2010:

On NuPack
The undo engine split out of Live Geometry the year before, GuiLabs.Undo, becomes one of the earliest packages on NuGet, in the weeks when it was still called NuPack. Kirill recalls that David Fowler urged him to upload it and wrote the .nuspec himself. The package is still on the feed today, with a 1.0.0 the current gallery dates to March 29, 2011, when nuget.org took over the original feed, and still describes itself as "a simple .NET Undo/Redo framework with mergeable actions and composite transactions", which is what runs Live Geometry's undo to this day.

I've been in the geometry business for 27 years. I just reconstructed the timeline of working on it since 1999: livegeometry.com/history

A History

Twenty-seven years of ruler and compass: from a Visual Basic program in Kharkiv to a WebAssembly app in the browser, by way of two false starts and one long silence.

A program begins in Kharkiv
Kirill Osenkov starts DG at the Kharkiv pedagogical university in Ukraine, under the supervision of Sergey A. Rakov. The language is Visual Basic 6.

MahApps.Metro. Remember that? I'm working on it again. Yes, old #WPF. Also the thing a lot of desktop apps are still written in, and those could stand to look a little less like 2012. Three style sets now. Pick one, swap a line in App.xaml, done. #MahApps #ControlzEx #XAML #dotnet
