  use Quicklisp[1] for installing/management of libraries, it works across platforms and implementations. [1] http://www.quicklisp.org/beta/ http://www.quicklisp.org/beta/

    Cells isn't in this month's Quicklisp because it didn't build for me. Kenny fixed it a few days later and it should be in December's edition.

In Python: http://pycells.pdxcb.net/ http://pycells.pdxcb.net/ As I mentioned in the Python spreadsheet thread (where I'm assuming this was found), this package has worked for everything I've tried to do with it but I do not believe it's maintained. Does anybody know of something similar for Javascript? A cells implementation would be preferred, but a spreadsheet engine will do.

  I'm not familiar with Cells or Pycells. Do you have any idea how this compares with Phillip Ebys Trellis[1] library? [1] http://pypi.python.org/pypi/Trellis/0.7a2 http://pypi.python.org/pypi/Trellis/0.7a2
  - grayrest 16y ago
    From the linked page: > Other Python libraries exist which attempt to do similar things, of course; PyCells and Cellulose are two. However, only the Trellis supports fully circular rules (like the temperature conversion example above), and intra-pulse write conflict detection. The Trellis also uses less memory for each cell (rule/value object), and offers many other features that either PyCells or Cellulose lack. I believe PJE was the mentor for PyCells and Trellis is PJE's take on the problem. I was following PyCells from its announcement since it seemed useful and if PJE isn't the mentor, he was heavily consulted.

When I clicked to download the source, there was an error. Is funny that common-lisp.net use python, and use it with errors. Just click on http://common-lisp.net/cgi-bin/viewcvs.cgi/cell-cultures/?cvsroot=cells http://common-lisp.net/cgi-bin/viewcvs.cgi/cell-cultures/?cv...

Shameless plug: I wrote something similar for Clojure. https://github.com/gcv/dgraph https://github.com/gcv/dgraph
- dkersten 16y ago
  Thats cool! I love Clojure and I love dataflow :) Just wondering how this compares to the dataflow library in clojure-contrib?
  - gcv 16y ago
    clojure.contrib.dataflow uses refs and works with side-effects on node cells. dgraph is (mostly) purely functional and its dependency graphs are persistent data structures, just like Clojure maps and vectors. I wrote dgraph specifically because I wanted those semantics.
    - dkersten 16y ago
      Thanks! Thats really awesome. That certainly makes it fit better with the rest of clojure than clojure.contrib.dataflow does. I'll probably end up using your library, it looks really good. Thanks for sharing.

I would love to work in this. In Lisp.
