6 hours	properly report and handle EOF when handling input HEAD main	Irene Knapp
	this should be a robust fix for the double-termination issue when compiling Force-Push: yes Change-Id: Ieaacdc232ea7e3036916d81139fc5c5a41087c64
7 hours	FreeBSD support via Linux compatibility mode	Irene Knapp
	this is done by setting the ABI version in the ELF header. many thanks to nortti for checking that things otherwise work, and validating that the approach makes sense in terms of FreeBSD's cultural expectations. Irenes don't have the ability to easily test this on our end, but this is an easy step that can improve compatibility. Force-Push: yes Change-Id: I3d55ed240c050839b8a11312f151d0809aef9031
8 hours	new feature "include"	Irene Knapp
	this was the subject of a bunch of thought. in most languages, we'd argue against having a text-based "include" feature, because there should also be a module system, and textual include subverts the module system because you can't assume everyone will use it. however, Evocation already very strongly encourages thinking of a program as a sequence of operations (this is after all the definition of a catenative language), and in particular the transformation system already relies very heavily on programs-as-text. so, it seems appropriate for Forth in general and for Evocation in particular. plus it was easy to implement, because all the infrastructure for it already existed to support the transformation system Force-Push: yes Change-Id: I76f778e44b8189ac7052890c881654d971e43c8d
11 hours	work around an issue caused by insufficient EOF handling	Irene Knapp
	thanks to nortii for reporting this. a real fix will come soon, but meanwhile this workaround should help. Force-Push: yes Change-Id: I38a4c3f148f69ff7c67e8dc00fac5e1351cc3eab
20 hours	typo fixes	Irene Knapp
	from Fred Crowson - many thanks! Force-Push: yes Change-Id: I369bd987b492ae01d8bed5b3ee9ee88073007c9c
22 hours	remove the magic words	Irene Knapp
	now all the command-line invocations are pleasingly short :) Change-Id: Ibe2b9f3b85ab3a51a9d95e3511b273664e6a8807 Force-Push: yes
23 hours	fix a minor bug in consume-from	Irene Knapp
	this had been interfering with intended behavior when hitting EOF. the intent was that key returns 0, then word also returns 0, and finally interpret or the active transformation also notices it's supposed to exit. consume was leaving a stray value on the stack, which prevented all of that. with this, it should be possible to remove the magic-word end delimiters for the transformations. end of an era :) that'll happen in a followup CL. Force-Push: yes Change-Id: Ib87afcf9199cc982250c4e66761c5fb056164fb7
24 hours	use file calls to read source during compilation	Irene Knapp
	as a result of this, the massive invocations to compile things are now shorter not all the way shorter, but significantly shorter :) because of where these changes are, this doesn't change the binary at all, so no new evoke.hex is needed (yay!) Force-Push: yes Change-Id: I35dfd065b2a4fc4bf1b80f402a07088efca43676
25 hours	all the syscall parameters are in the kernel's order now	Irene Knapp
	there was never a good reason for them not to be plus, the formerly bespoke ones use the generic helpers now; sys-open and sys-close are implemented; and a bug in push-input-buffer and pop-output-buffer is fixed unfortunately these were breaking changes, so there's another evoke.hex in this one Change-Id: Ifad58fc2fd757adcf89a69c59575565a10406ec2 Force-Push: yes
2 days	add a file descriptor field to the input buffer metadata struct	Irene Knapp
	and use it where appropriate Force-Push: yes Change-Id: I68c478460780a6ea6ac8d1cc437981e2899ef122
2 days	change sys-write and sys-read to take file descriptors	Irene Knapp
	and also sys-write didn't used to return a result this required a little massaging to make it build, the host evoke needed to not actually pass the file descriptor in evoke.e. for posterity: this was fixed by changing it everywhere else as a one-off, then changing it there and using the intermediate version to build the one being checked in now. this kind of weirdness is a thing we get the freedom to do because of the bootstrapped distribution model, though we still strongly prefer not to do it unless necessary. this breaking change would have had to happen at some point, so it's considered acceptable. the size of the diff to evoke.hex is larger than ideal. this raises the need to have a policy for when to regenerate it. since this is a breaking change, it's mandatory. it also seems important to commit a regenerated copy when a release is tagged. it will probably turn out to be a good idea to not regenerate it excessively, otherwise. it's possible that in the long run it might make sense to add name-mapping functionality to hex, just to make the diffs smaller. Force-Push: yes Change-Id: I2648b2577c5c21b126e46405e9888b5cb59aa0b7
2 days	typo fix, thanks mei&	Irene Knapp
	Force-Push: yes Change-Id: I287ce3331bb719b6a8920164f6550b472706b33b
3 days	release version 3.0 v3.0	Irene Knapp
	this is the first-ever release! wow :33333 have fun y'all!!!! Force-Push: yes Change-Id: Ifc95e4e63e4ee477b4c23d83a82f7a1e050f7925
3 days	mark a couple labels in hex.e as non-offset	Irene Knapp
	and rebuild hex.hex with the latest features Force-Push: yes Change-Id: Ic96c1ff6b06d2ecfb08a5c6829206460c0cdcf95
3 days	print comments in the hex dump at the offsets labels point to	Irene Knapp
	Force-Push: yes Change-Id: I1a0ea06380095da3e7702cab278c08bd21b292ca
3 days	no more than sixteen bytes on a line	Irene Knapp
	Force-Push: yes Change-Id: I7cd583d5a3ee72c316633ceb2efbb51a2fe46452
3 days	fresh line for alignment padding comments	Irene Knapp
	this fixes the thing where, if alignment padding was zero-length, the comment could wind up on the same line as the preceding thingy, causing confusion Force-Push: yes Change-Id: Ie7490370bf66a2f9b82df584236320bd88338e39
3 days	make the magic-comment tab stops function like real tab stops	Irene Knapp
	fun! fiddly! :D fixing one-off column alignment issues is like stimming for coders (which is to say, like stimming) Change-Id: I1037ec27b863f90117fb22a29ef52d0ba460c7d5 Force-Push: yes
4 days	add a special word for magic-comment tab stops	Irene Knapp
	Force-Push: yes Change-Id: I7ba182f5939aa3b5d280fb48673e2cc74d72e8ea
4 days	magic comments work in the log-load transform now	Irene Knapp
	that was pleasingly straightforward Force-Push: yes Change-Id: I92b66fbb37ed5df3ef3f733e8679747a9a232373
4 days	every byte in the hex output is now attributed	Irene Knapp
	wow!!!! Force-Push: yes Change-Id: I2b46837b5ff37b4339a9a4ba0ae52903854d5e99
4 days	indent curly-brace blocks in the log-load transform hex output	Irene Knapp
	Force-Push: yes Change-Id: I18e04f06390e85d4cd2c113094a137986ca2e54a
5 days	some basic indentation for parts of the log-load transform	Irene Knapp
	Change-Id: Ibfd4fa69a3d2abdaba162538f6386f7173af4311 Force-Push: yes
5 days	codeword annotations and such for the log-load transform	Irene Knapp
	this is everything outside of log-load-transform-one itself compile time is up to nine minutes though, due to the new backwards-scan thing. keeping the entries sorted might be better... Change-Id: I96058f0c9c043f7b8b681018e1178505caddbc62 Force-Push: yes
5 days	magic comments for all the high-level flow control in the label transform	Irene Knapp
	Change-Id: I5430e14e81c5981f358fda43c2f35ed47cafc29b Force-Push: yes
5 days	add a bunch more data- and entry-manipulation magic-comment commands	Irene Knapp
	now it's possible to make ;asm replace "docol codeword" with "self codeword", and it does Force-Push: yes Change-Id: I1a9b4cee8a3eee308cf421968d6a3cd92adba800
5 days	a new "data" concept in magic comments	Irene Knapp
	this is meant to handle variable-length stuff. it is now used to handle the string in the word entry headers. Force-Push: yes Change-Id: I8f3ce7dd93351639fbce82503324f3efe5def568
6 days	magic comments for a bunch more small stuff	Irene Knapp
	especially in the label-transform output there's more to do, but there are additional magic-comment features that would be handy, so we're checking this in now so that those can be cleanly kept in their own CL Force-Push: yes Change-Id: I97a67caddc3f3150c349b7956c1d715db909d1a9
6 days	give the names of codeword pointers in label-transform output	Irene Knapp
	under the hex transform, that is this also implements ndrop in quine, because it wasn't building evoke, and it checks in the updated hex.hex which reflects the more concise notation for integer constants. this brings all the builds into a clean state, for the moment. Force-Push: yes Change-Id: I243cf08c70b4a3af00ea5e0836c5596a32f1288b
6 days	better behavior in the crash handler when the dictionary is messed up	Irene Knapp
	a lot more defensive bounds checks Force-Push: yes Change-Id: Ib900471b8befe06dfa7994714b94ab4ebdc3f0fa
6 days	handle memory sliding in the hex transform	Irene Knapp
	wow!!!! that was big Force-Push: yes Change-Id: I504ae746d4424e46819357e6dad6d6eadec16b81
8 days	yeah okay, copying it wasn't necessary	Irene Knapp
	Force-Push: yes Change-Id: I9772f90f497a19c04ff6f9e261a5d9f262f79be7
8 days	fix the overwritten strings in the output	Irene Knapp
	this probably shouldn't have required copying them, but ah well, copying worked Force-Push: yes Change-Id: I239f2633c61867f6c42a5b76a0e978aff0875a9d
8 days	redo the hex dump comments for alignment to use the regular magic commands	Irene Knapp
	previously, alignment had been a special-cased type of metadata entry, with a special trap on packalign. now it uses the same programmable setup everything else does. much simpler, and prettier output. this CL also contains some modest reformatting of section headers in the hex dump Force-Push: yes Change-Id: I21554e92f6af6ddefa937dad8073b89657f85d64
8 days	added section headers and other formatting to all the parts of the hex dump	Irene Knapp
	Force-Push: yes Change-Id: Ie66d85fd171dfb45d1f3b6869bf94056ec8303af
8 days	do magic comments from the label transform when inside the hex transform	Irene Knapp
	the meaning of them in that setting is a bit different, which deserves to be documented eventually Change-Id: Ia7725bc776420c0ad62091a2e5100700868a6bfa Force-Push: yes
9 days	oops, didn't mean to comment that out	Irene Knapp
	Force-Push: yes Change-Id: I8fbf3d531b18904f2a01e6b05ff2822d6a015013
9 days	refactor hex-tilde-alternate to split out lexing	Irene Knapp
	note that lexing of the body of a magic comment was already separate, part of hex-tilde-replacement. however, hex-tilde-alternate had been responsible for lexing the sequence that introduces a magic comment. because we want to make separate versions of the alternate for each inner transform, the lexing needed to be factored out. this does result in more copying, but it doesn't appear to noticeably affect runtime. Force-Push: yes Change-Id: I51a780d1dadb99f09bddb9eaccb1af387bd0ce87
9 days	avoid repeated scanning of the metadata entries during formatting	Irene Knapp
	there was a test that had never been working, meaning the entire entry array was being scanned for every byte of output. even had that test worked, it would still have scanned on average half the array for every byte, so that'd be where the absurd runtimes were coming from. anyway, it works now. this gets a full hex transform invocation down from over thirteen minutes to under thirty seconds. learn your data structures and algorithms, kids. Force-Push: yes Change-Id: If075b256f77649fae9d2e56cb7404458ca39d189
9 days	place a trap inside the hex-transformed nlabel-transform-one	Irene Knapp
	this will be used to cause it to apply a tilde alternate, but the lexing code for that needs to be refactored first also, this has an implementation of nexit, a new flow-control word for a scary style of metaprogramming Force-Push: yes Change-Id: Ic7fe2d50a8ee21cf9fa5fef1fef4408c2935bb4c
9 days	add the ability for magic comments to happen in immediate mode	Irene Knapp
	but, don't do them, though, they aren't ready yet. for reasons described in the code. they're harmless, they don't cause crashes or incorrect output, they just don't cause any output at all. Force-Push: yes Change-Id: I5e45adc60f4e01e7bc54d9da8aa4fa5f8b708ddb
11 days	work on making the label transform pretty-print word entry headers	Irene Knapp
	this involved instrumenting label-create-alternate and some other stuff it also involved adding provide-string and provide-string-copy magic-comment commands Force-Push: yes Change-Id: I52f87decc02bf6f2516ee009f27c783a2c5bd715
11 days	explanatory text at the start of the hex transformed label transform code	Irene Knapp
	Force-Push: yes Change-Id: I695582905dea0c6e34981e803ef515c547eade40
11 days	swap the order of parameters to hexdump-between	Irene Knapp
	it was confusing from the start, and we had one too many issues with failing to remember it. finally taken care of :) Force-Push: yes Change-Id: I9782621f747e84d50d1794e3f1669cb5afb77038
11 days	fully verify the hex-transformed output of all Evocation-assembly words	Irene Knapp
	the verification included words that aren't used in Evocation itself. it also resulted in fixing several such words that were broken in ways that would have crashed. it was a very thorough verification. do honor to the effort that was put into it by always verifying that changes to amd64.e don't break it, from now on :) Force-Push: yes Change-Id: Ia1904f4b35f90772fd9dce79a0274627c547edbf
11 days	removed the #swap syntax	Irene Knapp
	everything has been carefully diffed to ensure there's no regression in the verified parts of the output Force-Push: yes Change-Id: I32c887c7ca8c132a49899d9ef327c8ff9fb782fb
11 days	semantic change to make subitem stack manip more convenient	Irene Knapp
	this allows a much cleaner style than the #swap notation, which will likely be removed soon Force-Push: yes Change-Id: If9898334356eb7c036f28afd22d435e00a84f6e2
13 days	refactor the metadata postprocessing a little for readability	Irene Knapp
	there's about to be a semantic change, but that will happen in a separate CL Force-Push: yes Change-Id: Ib32d542c02a640a964fdeed7bc16248b669d6a91
13 days	began to check and correct the exact hex-transformed instruction output	Irene Knapp
	the checking is only a little way down the file, but there's a new feature needed, so this is being checked in now to protect the work that's already been done Force-Push: yes Change-Id: If8c29d4b417288e5cfb2aa08ce6d41adadc64279
13 days	substantial additions to the README	Irene Knapp
	and also a prettier flame drawing Force-Push: yes Change-Id: I5896bfdee53c934b4c38861c8a9e9f5a966f7264
