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) .
