An experimental concatenative Python-based programming language.
Examples are in the examples directory. To see the (out of date and incomplete) spec, go to http://jmanuel1.github.io/concat-spec/.
Python 3.12 required.
Python code is formatted using Axblack
through a pre-commit Git hook. To
set this up in your clone of the repository, install the dev dependencies of
the project (by running pip install -e .[dev], for example), and then run:
pre-commit install
Now Axblack and pre-commit should be working! Whenever you commit a Python file, Axblack will be ran on that file. If Axblack makes formatting changes, you might need to try restaging and recommiting.
If you run the tests on Windows, you might need a
Rust installation for one of the tests. (The tests
depend on pywinpty to use Windows
pseudoterminals.)
If your Python is 32-bit, you may get Rust compile errors that make it look like
the standard library is missing (in particular, E0463: rustc --explain E0463).
As suggested by rustc, you can try adding the right standard library with
rustup target add <target>. I used the target i686-pc-windows-msvc even
though pywinpty claims to require x86_64-pc-windows-msvc to build from
source. Then set the environment variable CARGO_BUILD_TARGET to
i686-pc-windows-msvc and try to install pywinpty again.
Run the tests and get coverage info using coverage run -m nose2 --pretty-assert concat.tests. (Make sure you've installed the development dependencies first.)
Nota Bene: If you have concat installed globally, make sure to create and
enter a virtualenv before testing, so you don't end up running the installed
version.
Change the version number in setup.py. Upload will fail if you try to push
an existing version.
Delete the dist directory, if it exists.
rmdir dist /S
Build source and pure Python-3 distributions.
py -3 setup.py sdist
py -3 setup.py bdist_wheel
Upload.
twine upload dist/* [-r pypitest]
