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.
The modified implementations have been tested on Debian bullseye.
* prefer later Ubuntu image, hopefully reducing the image count
* for Ubuntu versions, prefer numerical versions to unsorted codenames
* prefer packaged build systems to local rebuilds
* prefer the current default version of each build system
* delegate resolution of indirect dependencies to apt
* xslt: remove intermediate run script. The initial motivation is to
provide an explicit path to the python3 interpreter, as the
versioned executable is not always in PATH.
* Add DEBIAN_FRONTEND=noninteractive to some Dockerfiles. This is to
workaround tzdata which prompts interactively by default.
* Debian/Ubuntu do not ship a python->python2 link by default.
* With the improved logo implementation in another branch, there is no
need anymore to tweat the garbage collector settings.
* logo: use upstream brandy compiler (instead of building).
* guile: adjust deb-src mechanism to build ucblogo and workaround doc
build bug.
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
OSH is a bash-compatible shell: https://www.oilshell.org/
reader.sh:
- Put the constant regex pattern in a string literal. This simplifies
it by removing mixed regex vs. shell quoting, and implicit
concatenation with $'\n'.
This is suggested by the bash manual:
https://www.gnu.org/software/bash/manual/bash.html#Conditional-Constructs
"Storing the regular expression in a shell variable is often a useful
way to avoid problems with quoting characters that are special to the
shell."
- Initialize __reader_tokens as an array, not a string.
https://www.oilshell.org/release/0.8.pre6/doc/known-differences.html#values-are-tagged-with-types-not-cells
env.sh:
Simplify quoting in 'eval' expressions. This quotes associative array keys,
which is required by OSH to avoid dynamic parsing.
https://www.oilshell.org/release/0.8.pre6/doc/known-differences.html#strings-vs-bare-words-in-array-indiceshttp://www.oilshell.org/blog/2016/10/20.html
core.sh:
Quote associative array keys. '<' and '>' are shell operators and OSH doesn't
have a special case when inside [].
----
With this change, OSH can run tests just like bash, e.g.:
$ osh impls/bash/stepA_mal.sh tests/step4_if_fn_do.mal
----
Test results are the same before and after this change:
$ NO_DOCKER=1 ./.travis_test.sh test bash
FAILURES:
SOFT FAILED TEST (line 295): (f (+ 1 1)) -> ['',true]:
Expected : '.*\ntrue'
Got : '(f (+ 1 1))\nfalse'
TEST RESULTS (for ../tests/stepA_mal.mal):
1: soft failing tests
0: failing tests
106: passing tests
107: total tests
- 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.
