Pulsar at ESUG 2026 (new Smalltalk IDE)

I've been at ESUG a few years ago. I can definitely recommend it if you want access to all kinds of Smalltalk and Pharo experts, and listen to all kinds of topics that contain a high amount of expertise.

I remember that I wanted a visual step by step debugger for a visualization library [1]. I was lucky enough to find the library maintainer himself. He liked the idea, and within just 30 to 60 minutes we programmed a prototype in (this was around ChatGPT 3.5, so pure hand coding).

Happy to see something related to ESUG so up in HN.

Smalltalk still has a small group of passionate people who love the language, the environment, and its concepts.

For some reason, Buenos Aires has a “large” group of Smalltalkers (large relative to the total, which is small in absolute terms). This group usually organizes the ESUG event in Argentina with very few sponsors.

not even a screenshot?

This is like Pharo but for Gnome. So, a good interface for an smalltalk, suferior to GNU Smalltalk. Altough GST can be used scripted, for sure.

Its odd that some words have a squiggly red underline in that image.

no pictures of the IDE?

I just had a realization: I've been hearing and reading about Smalltalk and how great (though slow) it was for the past 30 years … but I've never once seen an application, let alone a killer one.

Well, except for development environments.

Anyone know one that's worth looking at?

Now it seems there are two editors named Pulsar. This, and the successor to Atom.
