Huge amount of work. Does not even nearly compile, but it's nearer.

Added work on making namespaces threadsafe.

Things which should have been saved before the last commit. Sigh.

Lots more code written, and I think most of it's OK; but it doesn't compile yet.

Got most of the new memory architecture roughed out.

Firming up the roadmap for the 0.1.X prototype
2026-03-24 16:53:54 +00:00

Moved legacy code into archive, ready for a new rapid(?) prototype.
...
I may regret doing this!

Added an essay on the design of paged space objects; started experimenting in Zig.

Upversioned the C source tree to '0.0.7-SNAPSHOT', but proposing to start experimental

work towards 0.1.0 in separate source trees.

Ready for release 0.0.6 (still lots of bugs).

'Fixed' issue #8 ; but done so by introducing a goto. Not entirely happy about this.
2026-03-18 21:35:34 +00:00

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

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

Found and fixed a bug I did not previously know about in println.
2026-03-18 12:22:12 +00:00

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

Added the unit test for member!

Getting closer to tracking down the member bug, but cannot use debugger on laptop screen.

Tactical commit while working on the bignum bug, AGAIN.

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.

Very minor fixes/

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

Still not working, but I have increasing confidence I'm on the right track.

Established intern bug is in getting, not setting; improved exceptions.

More debugging output. Getting desperate!

Rewriting intern. This is badly broken, but I think on the road to better.

Very, very nearly ready for 0.0.6. Too tired to press the burron tonight.

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.

Whoops! Had the wrong debug tag on debug calls in equal.c

Greatly improved performance of equal for string like things.

let segfault bug "fixed". *But* I suspect there's memory leaking here.

Made eq and equal vararg functions, and appended ? to their names as predicates.

Fixed runaway recursion in cond. However, let is still segfaulting, and member

does not work correctly.

Fixed subtraction regression; added new subtraction unit test.

Careful debugging of the memory leak problem. At this stage,
...
stack frames for interpreted (but not primitive) functions appear not to be being
reclaimed, and the oblist doesn't seem to be being fully reclaimed.
2026-02-20 19:39:19 +00:00
8629e33f92
Added a flag, simplify to the arg list of make_ratio, so that we can
...
create ratios which would otherwise somplify to integers, in order to
make ratio arithmetic easier.
2026-02-15 23:47:28 +00:00

add_ratio_ratio fixed.
2026-02-15 17:38:54 +00:00

Arithmetic equality fixed.

Work on the equality of numbers. The good news: two additional unit tests pass.
...
The bad news: I'm getting segfaults.
2026-02-15 00:50:30 +00:00

Redone fixes to unit tests which I know I did this afternoon, so I've messed

up git somehow.

Stage one clean up of test files. Some unit tests are still creating temporary files in
...
the project root directory, which is still to be fixed; and *I think* known-failing
tests which I don't intend to fix immediately should be marked in some way.
