Lhogho: The Real Logo Compiler

I was studying Logo as it is in the NetLogo Agent-Based modeling program environment when I came upon Lhogho.

You have to click the 'logo' to enter the site. I was stuck on the landing page for some seconds.

It appears to be last updated 2012-10-15, but the documentation is great, it runs on Linux and Windows, and shows how you can turn it into a scripting tool from the Windows or Linux terminal. It makes standalone executables too.

Like Forth, you have the ability to crash your machine with low-level access. The whole download is under 1MB, and it has docs, examples, and worked out of the box on my Win 8 and 10 machines. Trying Linux tonight.

[Edit] One of the team, Pavel Boytchev also created Mecho, for creating "mecholets" animated 3d mechanisms, but I think it is Windows only. [1]

I found NetLogo waaaaay too complicated for when I just wanted to draw spirographs.

The last time I looked at Logo it came on floppies for Mac OS 8.

http://fmslogo.sourceforge.net/ looks more like what I remember.

NetLogo is not for drawing spirographs, but ABM - Agent-Based Modeling. I use it to quickly put together models of things like building evacuations. It is really easy to knock together a GUI and show people who are less technical the results of flow, exit number and widths, number of people, etc...

Lhogho is a compiled Logo, and I have been having fun just creating little programs in Logo, since I have not done more in Logo before other than some turtle graphics.

I always love seeing implementations of Logo that I haven't run across yet. Logo was my introduction to coding, back when I was in third grade in the mid-90s.
