The PicoLisp Wiki and other resources


2 min read

In this post I will present some further information resources on PicoLisp. Although it's quite a small language, there actually quite a number of very good resources online.

Previously I already wrote about the Mailing List and the IRC channel. What else do we have?


The official documentation can be found in the doc/ folder of your PicoLisp installation or on

A more artistic, associative approach to the documentation and PicoLisp in general can be found in the colorful Mindmaps created by Nehal Singhal.

The PicoLisp Wiki page

On you can find the official PicoLisp Website (of course running on PicoLisp!. On this site you can find a Wiki with many PicoLisp-related articles written by community members. They are loosely sorted by topic, like "web development", "database" or "Articles & Essays". In order to be able to contribute, you need to create an account first. Here you can learn how to contribute.

Not all of the tutorials are valid for the newest PicoLisp version pil21, so it can be helpful to check the publishing date at the bottom of the post.

Demos and Repositories

You can find some demo programs on as zip-file. Usually they run in pil21, resources for older PicoLisp versions are available on request.

Another large collection of PicoLisp examples can be found on the Rosetta Code Project and on the PLEAC Project.

Here you can find an overview of the algorithms.

It is possible that some of the examples are written for previous PicoLisp versions like picolisp 64 instead of pil21. The versions are mostly compatible, but if you experience that the examples don't work, it is probably because of this. The examples on this blog are all written and tested on pil21.

You can also find some more repositories and resources here.

PilCon - The PicoLisp Conference

About two times per month there is a video conference called PilCon on Jitsi. The date, time and link are usually shared in the PicoLisp mailing list. In order to consider different time zones, the meeting time is usually alternating between morning and afternoon (Europe timezone). Everybody is welcome to join and ask questions. Agenda requests are helpful but not mandatory.

A face to face meeting has been planned for summer 2020 in South Germany, but it needed to be postponed due to Covid-19 pandemic. A new date is not planned yet.

In general, the easiest way to get in touch with the community via the IRC channel. In this post, I described how to do this from the browser if you don't have a client.
