I’ve been playing around in Pharo [0] and it’s such an immersive experience! My first reaction was to compare to eMacs in that the editor/environment is the program and it can be edited, customized, extended… but Pharo/Smalltalk takes it to the next level of ease of use, discoverable and fun!
If you like the emacs-like aspect of Pharo, the Glamorous Toolkit project (which is built on top of Pharo) is worth checking out too. They recently released a digital notebook tool called Lepiter that has a lot of similarities to org-roam/org-babel: https://lepiter.io/feenk/introducing-lepiter--knowledge-mana...
Did they release it? The blog is about it but there's no link. This seems to be the site https://lepiter.com/ but it's just a form where you can give your email to "Register for fresh news."
It's released. It's not a separate download -- it's in the Glamorous Toolkit download (which makes sense from a Smalltalk perspective but may be weird if you're not used to it).
If you're on an iPhone, doubtless its autocorrect will assume that what you meant was the plural of that other wonderful Apple product from years past.
