What Hacker News says
9 sourcesWhat's interesting is that the redacted full thread alludes to some of these invisible aspects, and Radon appears to have a justification for doing things that way (though it's all blacked out so we cannot evaluate the merits of that argument).

https://github.com/replit/upm is likely one of the blacked-out bits in that email, as Radon says he wrote the README.
In Replit used legal threats to kill my open-source projectpipreqs' mapping was my first guess:
https://github.com/bndr/pipreqs/blob/master/pipreqs/mapping
Although it looks like they may have expanded beyond pipreqs:

In The Python Package CacheMac and windows too https://github.com/replit/upm#macos
In The Python Package CacheNo magic, it's automating and hooking into existing open-source tools. For Python its poetry (https://python-poetry.org/), not requirements.txt because UPM needs to present strong guarantees on reproducibility -- otherwise things like content-addressable caching wouldn't be possible. Poetry is open-source and UPM is too: https://github.com/replit/upm
Every Replit Python project can be downloaded and you'll have the spec file and the lock file so you can install the same dependencies locally.
In The Python Package CacheRepl.it also offers a more production ready version called Universal Package Manager https://github.com/replit/upm
In Magicimport.py: Python code that fetches its dependencies without complainingThe trend of putting developer tools behind a unified API is just awesome. Especially great for tool makers like us at Repl.it. We're investing a lot in this area too:
- UPM: universal package manager https://github.com/replit/upm
- Prybar: universal REPL interface for interpreters https://github.com/replit/prybar
In GitHub Super Linter: one linter to rule them allThanks so much for the mention. It's indeed a lot of work, but we've done so much with such a small team and it's only accelerating as we layer all of our solutions on top of each other. We're solving one problem at a time with focus on patterns and abstractions that makes it easily extensible and could support virtually any language.
With the Universal Package Manager (https://github.com/replit/upm) we're trying to encode the best practices in package management behind a single easy-to-use interface. One of the most fun features is that you can `import` or `require` a package and we'll just guess what you want to do, install the dependencies for you, generate a spec and lock file.
With prybar (https://github.com/replit/prybar) we're trying to create a universal interactive programming experience that behaves roughly the same for every la

nguage.
And, to be open-sourced soon, our window-tiling manager and workspace (https://repl.it/blog/ide), we're trying to build a framework that makes it so easy to build complex, plugin-based environments, such as IDEs, very easy to build.
We also leverage a lot of awesome open-source projects and standards, like the Language Server Protocol by VSCode/Microsoft, that abstract over language features and makes it easy to provide an amazing experience across languages.
Edit: if it's been a few months since you tried Repl.it, give it another try, we've made a lot of progress since then. Multiplayer is now out of beta, we have Git integration, and we've done a lot to make it faster and more reliable.
