2026-05-28better documentation of parameter order for arithmetic instructionsIrene Knapp
Force-Push: yes Change-Id: I02af0267657cf21fcf4e4d79457645da42f6798d
2026-05-28change the parameter order for memcopy and memmoveIrene Knapp
that was surprisingly involved, but it feels like the right thing to do Change-Id: Ia2f38c7278f4237cebd0435d27131fe32dbc3718 Force-Push: yes
2026-05-28add the ability to bind signal handlersIrene Knapp
and a useful example one ;) this also involved fixing the failure cases in input.e to handle EINTR correctly. it required a lot of tracing, but now the expected state of the stack is much better commented for next time. many thanks to @cks@mastodon.social who found code in the Go compiler which had the details of what's required in regard to the restorer, which made the whole thing work, and to @snowfox@tech.lgbt who did some experimental testing around the exact requirements. both those contributions are reflected in the documentation added with this CL. additional thanks to everyone who chimed in on the fedi thread, your comments kept us going! Force-Push: yes Change-Id: I97fd89426bf807df5565e011d3665f7e904fa138
2026-05-27deal properly with EINTR from sys-readIrene Knapp
this will be necessary to resume after running a signal handler. it had a bug where any error code other than ENOENT would be treated as a number of bytes read, resulting in a negative value for the buffer's logical length. amazingly this didn't crash, but it wasn't great. anyway now that's all fixed Force-Push: yes Change-Id: I1c2b45d8efd531c121c5695cdf0cc74609c80547
2026-05-25fixed the vim comment highlighting thingIrene Knapp
it needed to be a zero-width assertion, performance notwithstanding Force-Push: yes Change-Id: I033e3671401041406c247dcffa6b244c40544fd7
2026-05-24added a READMEIrene Knapp
at least it's a start :) Force-Push: yes Change-Id: I221a916c8d6ae5ac45c1d884232b31da89584ddc
2026-05-24added a program, hex.e, which will be the bootstrap strategyIrene Knapp
also added some instructions it needed Force-Push: yes Change-Id: Ia35280e2696167eb0662a5c3a9dc47840438da56
2026-05-23added a couple new instructionsIrene Knapp
this turns out to be fairly involved. hex bootstrap can't come fast enough ;) Force-Push: yes Change-Id: Ide5d2207d745ad07c40d3c9f457cd6b491bfbcf0
2026-05-23keyword wasn't workingIrene Knapp
and the transformation alternates were masking that. oops. Force-Push: yes Change-Id: I52a273b83cc00acdf70a20f01aeffc7feee85c76
2026-05-22fix our first binary reproducibility issue (wow)Irene Knapp
with this fix, the first-generation and second-generation builds are precisely identical it was an unused codeword in the bootstrapped docol, under the label transform, which inadvertently had a value from the host address space. the fix required some creativity. Force-Push: yes Change-Id: I05b373b4231fa093454fa31891784de16d81bb18
2026-05-22de-branch'd all the internalsIrene Knapp
so it's all just high-level flow control now, which makes it load in itself the output isn't identical on the first self-compilation, but it converges on the second with this, it is officially self-hosting. WOW. Force-Push: yes Change-Id: Ic14de1dae209b200cada269b07c3826c86fa494f
2026-05-22small changes towards self-hostingIrene Knapp
Force-Push: yes Change-Id: I6cf15b4e37b66a04afd5af9dfd9cc3d5eb52b894
2026-05-22okay s" ." and ' do their things nowIrene Knapp
Force-Push: yes Change-Id: I556334ea34157992d2b21306c941ad432cf41b4c
2026-05-22yesssss the interpreter fully works, wowIrene Knapp
haven't checked if it can compile itself yet :) Force-Push: yes Change-Id: I144981a04f09ecd0e9150369663ae8115bd39bdd
2026-05-22it runs!!!!!! it interactively reads input and everythingIrene Knapp
only some of that actually works, but hey, it's a start Force-Push: yes Change-Id: Ib82beb695be1a18de8aaaf3040b7c632851c6002
2026-05-21the interpreter fully compiles nowIrene Knapp
doesn't work quite yet. close :) Force-Push: yes Change-Id: I71b6e788790fe2ca8e07dae95e9ad6e39d0664c0
2026-05-21whew, okay, lots of interpret stuff implemented nowIrene Knapp
not fully tried though Force-Push: yes Change-Id: I19b39f2b982fde66863c710b6d458c3bd12bdf4a
2026-05-21okay, input buffers should work now (untested though)Irene Knapp
the word "variable" also needed special treatment, in the same way that "keyword" did. it's not immediately clear why. Force-Push: yes Change-Id: I15fae39b1b9ec928281150c76260940717b8e27a
2026-05-21dynamic.e is split up again, and more progressIrene Knapp
see dynamic.e, input.e, interpret.e, and flow-control.e there were a couple things in the log-load transform that need to work in compile mode, too Force-Push: yes Change-Id: I7caac3b9205f36f7e082a3fd280561d67e27942c
2026-05-21started cleaning up all the log-loaded functionalityIrene Knapp
it's in dynamic.e for now Force-Push: yes Change-Id: I4d0c5917eccd58cb881850faee0728d786010c27
2026-05-21Add high-level flow control to the log-load transformIrene Knapp
that was a lot Change-Id: I6ae9c371fe1fe6fd2757d20df73a748339fa89d1 Force-Push: yes
2026-05-21some comment stuff, and implement "keyword"Irene Knapp
Force-Push: yes Change-Id: Iecf4079b9629f9c041b7fe994b1a69b6ef7b6dd0
2026-05-21okay, s" and ." work all-the-way in the log-load transform nowIrene Knapp
wow those were hard ones. it's very squirelly what happens when. hopefully these new and reorganized docs will make it easier to understand next time... Force-Push: yes Change-Id: I8f3b86900ca1794afc3e607c2180dd05ea168cc7
2026-05-21thanks Verità! great catch :)Irene Knapp
Force-Push: yes Change-Id: I3308856db0fd1fc1b066f4e6d9925b4fc8830a4e

Force-Push: yes Change-Id: I1fc56015d3f2510157982a4387874f99a77cdc5f
2026-05-20tidied away core-plus.eIrene Knapp
it's merged into core now. that just made the most sense... a couple of its combinators are too useful to not use once you know about them Force-Push: yes Change-Id: I3857f353a8603960bebbf34f24572e3d5815f0de
2026-05-20the entirety of core.e now log-loadsIrene Knapp
wow!!!!!! wow making this work required implementing comma and keyword in the log-load transform Force-Push: yes Change-Id: If888d89c23389720840b49b72478e4826a15a269
2026-05-20so yeah, docol, exit, and lit all work in log-load nowIrene Knapp
also s" and ." work in the label transform, and are used to produce an important error message during the log-load routine, since we can't know whether log-loaded words exist until runtime sweet, right? Change-Id: I6a67139538c2cbcef40a1093202b2b4e0ad6febb Force-Push: yes
2026-05-20colon, semicolon, and compiled integers all work with log-load nowIrene Knapp
yay next up is to figure out why calling newly-defined docol-based words with it does not work Force-Push: yes Change-Id: I9c5f50d20f43ad8a15b6db58e046f1e0bb158266
2026-05-20create works now, and docol outputs successfullyIrene Knapp
having some trouble with colon Force-Push: yes Change-Id: I5fc0f4519bdd8de1033e24730f63296d8076782e
2026-05-20add a really powerful stack depth tracking feature for transforms to useIrene Knapp
also said feature seems to work, which is flatly astonishing just a little more now... Force-Push: yes Change-Id: I1bda7e99e524ac73a761859e86e01251e7d17525
2026-05-19rename all the label alternates to their longform versionsIrene Knapp
it's more readable Force-Push: yes Change-Id: I4be37c18da174eb1e9016bb1199a2ff2cf93f334
2026-05-19log-load-variable and label-keyword-alternate work nowIrene Knapp
yay :) Force-Push: yes Change-Id: Iae2e308ed8d786a9586bdc2583a6a9300282abae
2026-05-19yessssssssIrene Knapp
so okay, now all the machine code stuff is implemented and it builds without crashing the generated executable still crashes though, but this was enough work that it's getting a celebratory check-in Force-Push: yes Change-Id: I201e6912253647da58ef3537c735b478b0dca9fb
2026-05-18okay there's a strat for making the here/latest variables nowIrene Knapp
it doesn't work yet, but it's gonna the reason it doesn't work is that the new helper log-load-variable relies on the assembly-definition words being statically available, and they aren't yet that's fine though, this is still a huge change, worth checking in. why? well, it represents like 16 hours of debugging which culminated in some very minor changes to the semantics of the label transform, in order to make missing words easier to notice and debug. see comments for details. woooooo :D Force-Push: yes Change-Id: Id8334819d165ba9e3156ef2bf32008af748eac29
2026-05-17more progress on the log-load transformIrene Knapp
it generates most of the calls to create and comma, now Force-Push: yes Change-Id: Ib7620dca7a5bc5dd787e940ad18cf48c2a1bd529
2026-05-17implement log-load-create; add all the pack/unpack stuff to core.eIrene Knapp
Force-Push: yes Change-Id: I04dd65a9eec71f9b50c8875bdcbe5d4be59888d5
2026-05-16the skeleton of the log-load transform is in place nowIrene Knapp
it doesn't actually output anything, but it all runs without crashing Force-Push: yes Change-Id: I48f2e647044df0ae3db961c747cee31a8826ecf3
2026-05-16implement more internal wordsIrene Knapp

2026-05-16add a stub for the log-load transform, and a ton of documentationIrene Knapp
Force-Push: yes Change-Id: Ia1fe0e6aefaf6776bd69bca4a26ee0df0b555832
2026-05-16ah, oops, there was a bug in the label transform for compiled wordsIrene Knapp
fixed now also a bunch of small things towards adding a log-load transform Force-Push: yes Change-Id: I6eeb94d896a7e79092886d7b60e9404c31b2ba6f
2026-05-16word labels are now stored as offsetsIrene Knapp
also, the various address spaces in use are described better, and there's helper functions to convert between them. Force-Push: yes Change-Id: Idb56d2b6299d6e7071c9d42b2eb1138b17b85c69
2026-05-16it WORKS. WOW. nice.Irene Knapp
more specifically, a generated hello-world that uses cold- and warm-start, and both assembly and Forth words, correctly calls the kernel's exit() with a parameter provided by a literal. Force-Push: yes Change-Id: I9a08f9cdad6bd0037a41655eecff6debea5f9ac3
2026-05-16it's much closer, most of the labels work correctly nowIrene Knapp
Force-Push: yes Change-Id: I45662e60c0035758a2cd57d971031eb0562eccb7
2026-05-15the next-entry pointers in the generated dictionary work nowIrene Knapp
it was using the wrong value for the buffer start, messing up transform-offset Force-Push: yes Change-Id: I1d519b4de2df87930413ca440779337dbbe34d62
2026-05-15make the label transformation work all the way, no crashingIrene Knapp
the code doesn't quite run yet, that'll be a future CL Force-Push: yes Change-Id: I71e6a45127c1fc37906d902e36142c17afef2a21
2026-05-15document the assumptions between labels and transformsIrene Knapp
also some minor cleanup that ie. fixes alignment padding Force-Push: yes Change-Id: Ia8fcb9a44e05e37751cc1b8334aa72add7e62353
2026-05-15transform runs inside the label loop now, and is able to do compilationIrene Knapp
wow! yes. good. now it needs to actually generate label calls :) Force-Push: yes Change-Id: Ide4336e00aa6860fe55c956063303edc873c6d9b
2026-05-15fix things up so it gets through cold-startIrene Knapp
then it crashes on warm-start because warm-start doesn't exist yet Force-Push: yes Change-Id: I9eba481b31d48f9d32c3790f296204c5c8d90938
2026-05-15now there's a concept of pushing and popping input sourcesIrene Knapp
Force-Push: yes Change-Id: Ib8e8f342b7fa3773071eca36accf060f6c20f3be
