3 daysadd a buffer-start field to the hex output metadataIrene Knapp
Force-Push: yes Change-Id: I07e8170c88952bd3d490341db777f4e102da4acd
3 daysabstract the hex transform's metadata low-level pointer manipulationIrene Knapp
and move the docs on the data structure to where that is Force-Push: yes Change-Id: I607f2f9ce354026f27a8c6cbba020e29342fe450
4 daysstore the output buffer length in the hex transform's output metadataIrene Knapp
Force-Push: yes Change-Id: I77f18bba4ec9e6e806d2987cc107723ef91db802
4 daysadd a metadata structure for the hex transformIrene Knapp
the structure will eventually be populated from a few places, but for now, the proof-of-concept installs a complex hook that runs only on the call to "allocate" done at the top of "label-loop". the comment output code works: the metadata entries are output in the appropriate places in the dump! yay Force-Push: yes Change-Id: I15f20241e84b535c8407f9a190b22c9cb85227e6
4 daysimprove some commentsIrene Knapp
and remove a stray semicolon (oops) Force-Push: yes Change-Id: I1b26410f5f461f9026637b5509de3912defcd784
4 daysexpand the README with details on the bootstrapping goals and statusIrene Knapp
Force-Push: yes Change-Id: I1cde3ac2bfc10ccaa8be260a1a6a88684563ccf6
5 daysoops. read-to-buffer was tightly bound to that specific magic word. fixed.Irene Knapp
it had a baked-in assumption that the word was exactly eight bytes long, expressed in how it added the null terminator for stringcmp's benefit. Force-Push: yes Change-Id: I2a4f9967a3f564e16f163a22b70030a4bf938b5e
5 daysremove the hardcoded magic word from the hex transform alsoIrene Knapp
now there is no hardcoding of it anywhere Force-Push: yes Change-Id: Iaacbfb5fa07ded7e48075ba59f0bfdb9f9252cf4
5 daysmake read-to-buffer take its delimiter as a parameterIrene Knapp
since the recommended invocation to build Evocation (hehe) does the heavy lifting in interpreted mode, this required a new helper, allocate-string, which takes a string in the scratch space and properly allocates it so it won't be overwritten by future allocations Force-Push: yes Change-Id: Ia73612a65fd7c11af5fe110c573c23c16b777112
5 dayschange the transforms to take their end delimiters as parametersIrene Knapp
this will not be useful until read-to-buffer also does, but it's a step towards that Force-Push: yes Change-Id: Icf03088c9e52e427a5c130949e9ba85655d59044
2026-06-12it spits out correct hexIrene Knapp
no comments yet, of course. also no way to run it on evoke itself yet, due to the buffer thing. Force-Push: yes Change-Id: Ia1d7cc06bd3da59a5d272e1c04606c25d46acee5
2026-06-12the hex transform successfully runs (as an nop) on hex.e nowIrene Knapp
this seemed worth checking in Force-Push: yes Change-Id: I6bd81497d83883e0961f46b9e77fde97d1cad661
2026-06-12first steps towards the hex transformIrene Knapp
quite a lot is implemented, but there is quite a lot still to go. at any rate it compiles cleanly and this seemed like a good point to check things in. Change-Id: I634bb3b2f1b10702cf63cb73c0a995983b5041f2 Force-Push: yes
2026-06-11add ascii to the hexdumpsIrene Knapp
yay! that helps a lot (as tempting as it was to keep doing it mentally forever...) Force-Push: yes Change-Id: I7a213bc46913d00f9a9d3f49bcb22bfed248a010
2026-06-11clean up the entry flag bits a bitIrene Knapp
Force-Push: yes Change-Id: I7a5f4033bf80dfd3754de564ab49233459a952c5
2026-06-06more docsIrene Knapp
Force-Push: yes Change-Id: I16f8271c2629270f65e58e3a642511745ce136c1
2026-06-06also a wrong comparison in scalefieldIrene Knapp
also due to @atax1a@infosec.exchange Force-Push: yes Change-Id: I2e7797772c31fb11decf2a9de65c0e802ca5697a
2026-06-06the encodings in reg32 were missingIrene Knapp
this worked by coincidence since it's only ever called in one place, to encode :eax, whose encoding happens to be 0. oops. thanks to @atax1a@infosec.exchange for spotting this Force-Push: yes Change-Id: I4cddbcd370a5d0c7db2f8733431bfda388022a22
2026-06-05filled out a premortem for Evocation :3Irene Knapp
Force-Push: yes Change-Id: If9584709d96ca98ed6e03d5987549df9eb357c33
2026-05-29make the crash handler also print the word crashIrene Knapp
Force-Push: yes Change-Id: Ib47e3c68e08d286f01dddecfbd565f881b94f01f
2026-05-28comment fixesIrene Knapp
Force-Push: yes Change-Id: I5c0e7abaebb9388f7900dbae8bde1b1cd528ac32
2026-05-28docs fixed for attach-string-to-input-bufferIrene Knapp
(also see the one in input.e) Force-Push: yes Change-Id: I80910cfdb5e3de6f8b1db69a9c630a21b2f92f4a
2026-05-28yeah the litpack* variants won't be needed againIrene Knapp
they were not a very effective optimization in light of the log-load stuff Force-Push: yes Change-Id: Ie0b51dddfda2b44c986a078580cc15be88193755
2026-05-28make a decision on where to keep find-in and document itIrene Knapp
Force-Push: yes Change-Id: I5e8d8ae4a6e07c2dfa38abc7b19a962932a210bf
2026-05-28swap the parameters to "entry-flags!"Irene Knapp
Force-Push: yes Change-Id: I11f3eb1079d27a7306d6ed1e8e4b9fd6fb7d3a4a
2026-05-28document "near" calls (sort of)Irene Knapp
Force-Push: yes Change-Id: Ice00213f2e4b79f9aa44e6ccc5a70d951f7f762d
2026-05-28move next-newer-entry-in and oldest-entry-in into dynamic.eIrene Knapp
it's starting to get concerning how all this stuff needs to go in quine.asm but hopefully the hex transform will fix it Force-Push: yes Change-Id: I840e77c96fa0555bc01b9604d09f5ac4903d48bf
2026-05-28moved pack-raw-string into core.eIrene Knapp
Force-Push: yes Change-Id: I0940c0c21580e810716a5f61b95fd520c464ab9e
2026-05-28rename transform-state to transformation-stateIrene Knapp
this makes it unambiguously a noun phrase Force-Push: yes Change-Id: Ibc24821d70aaf6bc88ae5bf5e864e5b4db94dae5
2026-05-28yay we already had high-level flow control thereIrene Knapp
so the TODOs are unneeded Force-Push: yes Change-Id: I13d1316d22b52238076d6f17d05062671e4724e4
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
