a302663b32 Well, I really made a mess with the last commit; this one sorts it out. 2026-03-31 20:09:37 +01:00
1196b3eb1d read isn't written yet, but I think all the building blocks I need for it are.
Compiles and runs; does nothing yet.
2026-03-31 20:01:01 +01:00
364d7d2c7b Compiles again, now with bootstrap-layer print implemented, but not yet tested.
To get print implemented, I also had to implement a lot of other things.
2026-03-31 15:05:44 +01:00
2b22780ccf This once again does NOT compile. I've done work on macros; they don't work yet.. 2026-03-30 21:49:08 +01:00
e3f922a8bf Added character as a first class object. Stepped through a run; it all works. 2026-03-30 13:29:26 +01:00
a8b4a6e69d My monster, it not only compiles, it now runs! 2026-03-30 11:52:41 +01:00
60921be3d4 Much more progress, still doesn't compile. 2026-03-30 09:35:34 +01:00
1ce9fbda77 Still not fixed... 2026-03-29 17:25:08 +01:00
04bf001652 Progress, but it still doesn't build. I think I'm close, now... 2026-03-29 12:03:31 +01:00
00997d3c90 Down to to compilation errors. Had to reinstate individual size-class headers. 2026-03-29 11:07:30 +01:00
cae27731b7 Huge amount of work. Does not even nearly compile, but it's nearer. 2026-03-28 23:46:14 +00:00
1afb1b9fad Added work on making namespaces threadsafe. 2026-03-28 11:56:36 +00:00
154cda8da3 Added a 'state of play' update; changed the strapline in Home.md 2026-03-26 09:20:41 +00:00
57c5fe314a Things which should have been saved before the last commit. Sigh. 2026-03-26 09:03:27 +00:00
6c4be8f283 Lots more code written, and I think most of it's OK; but it doesn't compile yet. 2026-03-26 09:01:46 +00:00
604fca3c24 Got most of the new memory architecture roughed out. 2026-03-25 11:24:33 +00:00
19d6b0df29 Firming up the roadmap for the 0.1.X prototype 2026-03-24 16:53:54 +00:00
914c35ead0 Moved legacy code into archive, ready for a new rapid(?) prototype.
I may regret doing this!
2026-03-24 16:25:09 +00:00
09051a3e63 Added an essay on the design of paged space objects; started experimenting in Zig. 2026-03-23 18:47:00 +00:00
99d4794f3b Upversioned the C source tree to '0.0.7-SNAPSHOT', but proposing to start experimental
work towards 0.1.0 in separate source trees.
2026-03-19 13:59:06 +00:00
788cb48b37 Ready for release 0.0.6 (still lots of bugs). 2026-03-19 13:38:50 +00:00
a20c956288 'Fixed' issue #8; but done so by introducing a goto. Not entirely happy about this. 2026-03-18 21:35:34 +00:00
dc5cac0bd8 Work on the 'member?' bug - (issue #8) -- which turns out to be assoc/interned.
Progress has been made, but this is not fixed.
2026-03-18 20:44:18 +00:00
7d0ce67373 Fixed a segfault when the system can initialise no more pages.
Still not fixed the `member?` bug.
2026-03-18 13:27:19 +00:00
69b199fecd Found and fixed a bug I did not previously know about in println. 2026-03-18 12:22:12 +00:00
54a99b6796 Working on the member? bug. No fix, but some improvements in debug message format.
The bug is actually either in `cond` or in `cdr`, but I'm finding it extremely hard
to trace.
2026-03-18 11:53:48 +00:00
109d400f00 Added the unit test for member! 2026-03-16 15:28:09 +00:00
de50a30be2 Getting closer to tracking down the member bug, but cannot use debugger on laptop screen. 2026-03-16 15:26:12 +00:00
d42ece5711 Tactical commit while working on the bignum bug, AGAIN. 2026-03-14 21:20:23 +00:00
7f34601523 Well, that was easy! Stack limit now working. 2026-03-14 16:58:55 +00:00
d1ce893633 This is broken, but the stack limit feature works. Some debugging needed. 2026-03-13 23:42:57 +00:00
2536e76617 Added 'depth' counter to stack frames. The idea is two-fold:
1. You can limit runaway recursion by binding a symbol *max_stack_depth* in the environment
2. You can limit the number of backtrace frames printed.

However, neither of these have been implemented yet.
2026-03-02 11:10:29 +00:00
72a8bc09e0 Very minor fixes/ 2026-03-01 20:37:16 +00:00
3a1f64d7ff Well, I'm back to the same failed unit tests as the develop branch
and I *feel* that the intern code is better. But it's not without
problems and I don't think I can release at this. But it may be
ready to merge back.
2026-03-01 20:04:21 +00:00
bcb227a5f9 Still not working, but I have increasing confidence I'm on the right track. 2026-02-28 18:09:48 +00:00
a1c377bc7c Established intern bug is in getting, not setting; improved exceptions. 2026-02-28 15:15:42 +00:00
54f6f023c6 More debugging output. Getting desperate! 2026-02-28 12:24:59 +00:00
72548097cf Rewriting intern. This is badly broken, but I think on the road to better. 2026-02-28 11:21:11 +00:00
145a0fe5a7 Updated the state of play. 2026-02-27 04:03:08 +00:00
1900bca706 Very, very nearly ready for 0.0.6. Too tired to press the burron tonight. 2026-02-27 02:43:21 +00:00
b720211b7b Made the string returned by c_type null-character terminated. Fixes #6.
This is probably the wrong fix; probably I should have fixed read_string
so that it did not create null-character terminated strings, but it will
do for now. Probably will revisit.
2026-02-26 21:14:39 +00:00
f21f763f94 Work on documentation. 2026-02-26 12:12:57 +00:00
dd90b84241 Work on documentation 2026-02-26 00:06:19 +00:00
af21e506ef Whoops! Had the wrong debug tag on debug calls in equal.c 2026-02-25 22:16:14 +00:00
Simon Brooke
ffceda5edc Greatly improved performance of equal for string like things. 2026-02-25 22:10:37 +00:00
Simon Brooke
90e862cc59 let segfault bug "fixed". *But* I suspect there's memory leaking here. 2026-02-25 20:13:57 +00:00
Simon Brooke
3665326c55 Made eq and equal vararg functions, and appended ? to their names as predicates. 2026-02-25 15:24:02 +00:00
Simon Brooke
8c63272214 Fixed runaway recursion in cond. However, let is still segfaulting, and member
does not work correctly.
2026-02-25 11:17:40 +00:00
d34d891211 Fixed subtraction regression; added new subtraction unit test. 2026-02-24 09:08:41 +00:00
62ebaf9819 Added logical operators and, not and or. Closes #3 2026-02-24 01:45:51 +00:00
