Old versions of Lurch
Lurch was first conceived in about 1995, but work was only sporadic and informal for most of the time since then. From 2008--2012, an intense period of work was supported by NSF DUE CCLI grant #0736644, followed by a break for redesign, and then reinvigorated work from about 2019 onward, resulting in the latest version.
This page is for historical purposes only, and lists old versions of the software no longer used or suppored. Again, we encourage users seeking the current version to visit our main page.
They are listed in chronological order.
Desktop application, 2008--2014
Work on this project was supported by NSF DUE CCLI grant #0736644 from 2008-2012, resulting in a desktop application for Windows, Mac, and Linux systems. That desktop app has several drawbacks that motivated our work on the latest version, most notably very slow computation and a less than reliable user interface. Again, it's mentioned here for historical purposes only; we recommend using the newest version.
Lurch Web Platform, c2017
Our first attempt to move our desktop application to the web resulted in a suite of tools for web-based word processing with semantic features embedded in the document and feedback graphics overlaid on top of the document. Subsequent improvements in web-based word processors (particularly TinyMCE) and our own decisions to streamline our design made it so that we did not end up using most of these tools in the long run. We mention them here for archival purposes only.
- First attempt at moving Lurch to the web, no longer actively developed or supported, including small example apps that use that web platform, documented here.
- A partial implementaton of the OpenMath standard in JavaScript
- cloud-storage - A JavaScript interface to cloud storage providers, used in our app for saving Lurch documents to Dropbox
- loadsave-plugin - A TinyMCE plugin providing a UI and other tools for loading and saving documents written in the editor
