From 71e4f3812982dba2efb471283d310224e8db363e Mon Sep 17 00:00:00 2001 From: "Kartik K. Agaram" Date: Wed, 3 Mar 2021 22:09:50 -0800 Subject: 7842 - new directory organization 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. --- linux/tile/README.md | 33 +++++++++++++++++++++++++++++++++ 1 file changed, 33 insertions(+) create mode 100644 linux/tile/README.md (limited to 'linux/tile/README.md') diff --git a/linux/tile/README.md b/linux/tile/README.md new file mode 100644 index 00000000..a13f7662 --- /dev/null +++ b/linux/tile/README.md @@ -0,0 +1,33 @@ +A programming environment that tries to [“stop drawing dead fish”](http://worrydream.com/#!/StopDrawingDeadFish). + +screenshot + +To run: + +``` +./translate_mu apps/tile/*.mu +./a.elf screen +``` + +To run tests: + +``` +./a.elf test +``` + +To run a conventional REPL (for debugging): + +``` +./a.elf type +``` + +## hacking + +Unlike the top-level directory, this is just a prototype so far.
