We created a new OTF font (available at https://github.com/certik/slabikar-otf), which works with XeLaTeX and Tectonic, but fails with LuaLaTeX with the following error. Do you know if this is an...

One way to do that is to implement Bash and Windows Batch backends for minixonsh. Then start generating the two files from a single Xonsh script automatically. That way Conda...

Merging with xtensor?

Would it make sense to contribute this to `xtensor` itself, or is it better as a separate library as it is now? I think @SylvainCorlay, @wolfv and others might be...

String to int conversion in ASR

4

Figure out a clean way to represent and implement string to int conversions in ASR. Then figure out how to hook it up in LPython. Discussed at https://lfortran.zulipchat.com/#narrow/stream/311866-LPython/topic/String.20to.20Int.20conversion.

The Windows tests fail, but the CI passes

Here are the freedoms that we have in implementation dictionaries: * Hash function * load factor / initial size of an array * array resizing strategy (rehashing or not) *...
