LispMe Manual

Intro Screen Icon Ever wanted to carry a lisp machine in your shirt pocket? Now this is possible with the LispMe Lisp system for the Pilot PDA... so much for marketing, which isn't really necessary, as LispMe is basically cheap shareware. Look here for an overview of LispMe's features.

Overview

LispMe is a Scheme compiler and runtime system running on the Pilot PDA. It is mainly intended to have a tool for quickly trying ideas and algorithms, not to develop major applications for the Pilot, as the resulting code has rather limited support for user interaction.

Features included:

Features omitted: For the top level, loading of sources etc. LispMe uses a unique concept not found in other similar systems but fitting (IMHO) very good to the Pilot's "flavor".

LispMe uses the memo pad as source editor, so all your LispMe code is automatically backed up with hotsync and you can import/export source code like any other text with your desktop PC.

All LispMe memory is held in a database, so switching to other applications and restarting LispMe again is possible without destroying the current image.

Legal Stuff

I take no responsibility for any damage this program may cause to your Pilot or your databases stored on your Pilot. You should backup your Pilot databases before installing LispMe. LispMe has been tested thoroughly on CoPilot emulator, on my own Pilot 1000 with 1 meg RAM running System 1.06 and 2.04, my new Palm III running System 3.00, and several other Pilots including Pilot 5000 and PalmPilot Pro and different software/hack configurations and works fine.

If you like LispMe and use it more than occasionally, please register it at the adress below for 10 US$ or equivalent. Registering will help improving LispMe and developing other Pilot software. Registered users will receive future versions by email. The program included is fully functional (;-)) and not crippled in any way, i.e. it

I don't like this kind of programs and therefore LispMe is fully usable even without registration, though you are requested to register LispMe when you find it useful.

MathLib is a free shared library that can be used by any OS 2.0 Pilot program that needs IEEE 754 double precision math functions. It's distributed under the terms of the GNU General Public License, and is freely available with full source code and documentation at the MathLib Information web page. It's not a part of LispMe, and you're not paying anything for its use; a copy is simply included in this archive for your convenience.

Parentheses Hack is freeware! Why charging fees for a simple little hack that I wrote in one afternoon?

To use Parentheses Hack, you need to install HackMaster on your Pilot. You can get it here. Please note that HackMaster is shareware, so you should register it.

Please send comments, bug reports, money (cash preferred, please no international checks) to this adress. When sending bug reports, please include source memos, expression evaluated and information about your configuration (OS version, active hacks)

I'm planning to build a source code repository, so feel free to mail any interesting LispMe code to me.
