OK, the problem is that make_frame fails to put the arguments into the frame.
...
I do not (yet) know why not, but that is the problem.

Initialisation almost succeeds. nil and t are successfully instantiated.
...
We then go into a mess of exceptions which trigger exceptions until we run out
of allocatable memory, but all those exceptions and stack frames are correctly
allocated and torn down again afterwards, so.... sort of good?

Whoops! several new files missed from recent commits.

Added debug messages to initialisation functions, but getting a segfault.
...
Not going to debug that tonight!

More code, closer to working, still builds.

Many more ops written, and it compiles. Nothing works yet.

Things that are self-evaluating can self-evaluate.

Added a note on things to read for the compiler.

Converted everything to the new lisp calling convention.

I think read will now read integers and symbols, but it's untested.
...
Everything compiles.

Further small changes on the way to a reader.

Well, I really made a mess with the last commit; this one sorts it out.

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

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.

This once again does NOT compile. I've done work on macros; they don't work yet..

Added character as a first class object. Stepped through a run; it all works.

My monster, it not only compiles, it now runs!
2026-03-30 11:52:41 +01:00

Much more progress, still doesn't compile.
2026-03-30 09:35:34 +01:00

Still not fixed...
2026-03-29 17:25:08 +01:00

Progress, but it still doesn't build. I think I'm close, now...

Down to to compilation errors. Had to reinstate individual size-class headers.
2026-03-29 11:07:30 +01:00

Huge amount of work. Does not even nearly compile, but it's nearer.
2026-03-28 23:46:14 +00:00

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
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

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

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.
2026-02-28 15:15:42 +00:00

More debugging output. Getting desperate!

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