Newer versions of sbcl now have the same sxhash issue on compound types
as the other common lisp implementations. So always dereference the
underlying base type when generating a hash. This fixes the bug in newer
sbcl that was resulting in `get` and `contains?` not working for
hash-maps.
The update from ubuntu:vivid to ubuntu:20.04 update the version of sbcl
from 1.2.4.debian to 2.0.1.debian. This resulted in the cl-launch based
build process no longer working: dependencies were not resolved (but
running it several times would eventually resolve them. So use an sbcl
build command directly when building for sbcl.
Note: updating the image to ubuntu:24.04 upgrades the version of sbcl to
2.2.9.debian. Something about that version breaks how we do hash-maps.
They become temperamental: hash-map creation often results in a nil
object returned and doing (get hm key) usually results in nil returned
even if the key shows as being present.
Explictly select python 3. The `python2` and `python` packages will
be removed from Ubuntu. Until each call site is fixed, install a
/usr/local/bin/python symbolic link as a non-intrusive work-around
(.deb packages do not interfer with /usr/local).
Add an explicit maintainer for bbc-basic.
Undo some cosmetic changes in order to reduce the global diff, this
merge request will probably be sqashed before acceptance.
Move lib{readline,edit}-dev out of the generic part.
Use existing .deb packages for GHDL and vim.
See issue #587.
* Merge eval-ast and eval into a single conditional.
* Expand macros during the apply phase, removing lots of duplicate
tests, and increasing the overall consistency by allowing the macro
to be computed instead of referenced by name (`((defmacro! cond
(...)))` is currently illegal for example).
* Print "EVAL: $ast" at the top of EVAL if DEBUG-EVAL exists in the
MAL environment.
* Remove macroexpand and quasiquoteexpand special forms.
* Use pattern-matching style in process/step*.txt.
Unresolved issues:
c.2: unable to reproduce with gcc 11.12.0.
elm: the directory is unchanged.
groovy: sometimes fail, but not on each rebuild.
nasm: fails some new soft tests, but the issue is unreproducible when
running the interpreter manually.
objpascal: unreproducible with fpc 3.2.2.
ocaml: unreproducible with 4.11.1.
perl6: unreproducible with rakudo 2021.09.
Unrelated changes:
Reduce diff betweens steps.
Prevent defmacro! from mutating functions: c forth logo miniMAL vb.
dart: fix recent errors and warnings
ocaml: remove metadata from symbols.
Improve the logo implementation.
Encapsulate all representation in types.lg and env.lg, unwrap numbers.
Replace some manual iterations with logo control structures.
Reduce the diff between steps.
Use native iteration in env_get and env_map
Rewrite the reader with less temporary strings.
Reduce the number of temporary lists (for example, reverse iteration
with butlast requires O(n^2) allocations).
It seems possible to remove a few exceptions: GC settings
(Dockerfile), NO_SELF_HOSTING (IMPLS.yml) and step5_EXCLUDES
(Makefile.impls) .
vivid packages are no longer available.
There are still implementations that use vivid because updating to
xenial was not sufficient to get them working again.
- Add a `vec` built-in function in step7 so that `quasiquote` does not
require `apply` from step9.
- Introduce quasiquoteexpand special in order to help debugging step7.
This may also prepare newcomers to understand step8.
- Add soft tests.
- Do not quote numbers, strings and so on.
Should ideally have been in separate commits:
- elisp: simplify and fix (keyword :k)
- factor: fix copy/paste error in let*/step7, simplify eval-ast.
- guile: improve list/vector types
- haskell: revert evaluation during quasiquote
- logo, make: cosmetic issues
- Reorder README to have implementation list after "learning tool"
bullet.
- This also moves tests/ and libs/ into impls. It would be preferrable
to have these directories at the top level. However, this causes
difficulties with the wasm implementations which need pre-open
directories and have trouble with paths starting with "../../". So
in lieu of that, symlink those directories to the top-level.
- Move the run_argv_test.sh script into the tests directory for
general hygiene.
