#elixir #erlang

What is the most complex code you have ever seen? Mine was written in #css. Yeap, styles grow so big and so complex really fast. And here's the tool to prevent it.

Write #shell and #python code together: https://github.com/lamerman/shellpy

Yes, this is wild.

Awesome #elixir tool to create object-ish structs and new data types with real encapsulation. Create smart constructors, private and immutable fields, sum types and many other fun things. https://github.com/timCF/calculus

"Zero setup" cross compilation and "cross testing" of #rust crates: https://github.com/rust-embedded/cross

Something like tox from #python land.

What's yours? Mine is somewhere at 50ms.

Introducing Revery! Native apps builder with #reason and #ocaml with almost no overhead! https://github.com/revery-ui/revery

Real #python applications have real data, and real data nests. Objects inside of objects inside of lists of objects.

glom is a new and powerful way to handle real-world data, featuring:

- Path-based access for nested data structures
- Readable, meaningful error messages
- Declarative data transformation, using lightweight, Pythonic specifications
- Built-in data exploration and debugging features

​​This is a plugin to facilitate image comparison for #matplotlib figures in #pytest: https://github.com/matplotlib/pytest-mpl

Looks awesome! #python

​​A neat #haskell little one liner to avoid duplicating logic across a -> b and b -> Maybe a

It is also implemented in relude library: https://github.com/kowainik/relude/blob/daf6868ac43f634d5f7c0003a3841ab70dbffbb3/src/Relude/Extra/Enum.hs#L38-L62

​​Keeping your system up to date mostly involves invoking more than a single package manager. Topgrade tries to solve this problem by detecting which tools you use and run their appropriate package managers: https://github.com/r-darwish/topgrade

Enforcing boundaries in #elixir projects without requiring the extra ceremony of umbrella apps: https://github.com/sasa1977/boundaries

Awesome tool to enforce better architecture and a very neat use-case of a custom mix compiler!

​​This ESLint plugin lets users write simple #eslint rules right in their config by leveraging the power of ESQuery, which is a #CSS-selector-like library for ASTs: https://www.npmjs.com/package/eslint-plugin-esquery

The optics family of #haskell packages make it possible to define and use Lenses, Traversals, Prisms and other optics, using an abstract interface. They are roughly comparable in functionality with the lens package, but explore a different part of the design space: https://github.com/well-typed/optics
