Yes, SISCOG is still kicking. From last year's European Lisp Symposium: https://www.youtube.com/watch?v=hMVZLo1Ub7M

Obrigado. Thanks.

I was aware of the company when I was still living in Lisbon, a few decades ago.

I myself run web-apps and scripts for clients. Didn't ditch Django yet but working on that.

+1 to explore Coalton. It's also talked about on this website and often by its authors.

Links to Coalton and related libraries and apps (included Lem editor's mode and a web playground): https://github.com/CodyReichert/awesome-cl/#typing

lparallel's website is back here: https://sharplispers.github.io/lparallel/ :) (https://github.com/sharplispers/lparallel)

Lem's Coalton mode looks good: https://lem-project.github.io/modes/coalton-lang/

Nice, pretty much what I had in mind. I think there could be some interesting potential there tooling wise. Combining a highly dynamic interactive environment with a good statically typed language sounds fascinating to me and it's something that at least to my knowledge has never been seriously tried. Only Strongtalk comes to mind but I have no idea how it was like in practice, and I assume the type system was something closer to Java.

I'd prefer that a LispWorks user answer, but there are quite a few interesting features, such as:

- tree shaking and small binaries (±5MB a GUI app)

- the CAPI cross-platform and native GUI toolkit

- mobile platforme runtime (iOs, Android)

- its Java interface

- its KnowledgeWorks system for "rule-based, object-oriented, logical, functional and database programming"

- more?

ps: today we maintain a list of pretty decent libraries: https://github.com/CodyReichert/awesome-cl/

I'm a lispworks user for a few projects. The killers, generally, for an enterprise project are the smaller binaries and java interface. I know of a few places that write gui apps in lispworks, but many (most?) projects with a user interface use some web framework stuff and only do the backend in lisp. The java is a killer feature for lisp adoption. A lot of companies use java heavily and being able to easily interface with that stuff is often a technical requirement and if not a technical one, a management requirement.

I think LispWorks is fine (also look at these plugins https://github.com/apr3vau/lw-plugins - terminal integration, code folding, side tree, markdown highlighting, Nerd Fonts, fuzzy-matching, enhanced directory mode, expand region, pair editing, SVG rendering…) but I had this feeling with the newer web-based Allegro IDE (the poor syntax highlighting surprised me, did I do sthg wrong?).
