Installing uLisp

This download is a single text file. To compile it in the Arduino or Energia IDE either save it as a text file and rename it to a .cpp file, or copy and paste the text into a new empty project file.

Download the latest Arduino IDE from arduino.cc, or the latest Energia IDE from energia.nu.

To install uLisp on the BBC Micro Bit see BBC Micro Bit.

Note that saved images are not generally compatible between different versions of uLisp.

Compile options

The uLisp sources provide the following compile options:

Option	Default	Description
checkoverflow *	enabled	Generates an error if underflow/overflow occurs in arithmetic operations.
resetautorun	disabled	Loads, and optionally runs, an image using load-image on reset.
printfreespace	enabled	Prints the number of free objects before the uLisp prompt.
serialmonitor	enabled	Allows the use of the serial monitor to download programs.
printgcs	disabled	Prints the amount of space reclaimed after each garbage collection.
sdcardsupport	disabled	Provides SD card support using with-sd-card.

Test suites

The following files contains test suites I use for testing each release of uLisp. You may find these useful if you are porting uLisp to another platform:

Test suite - 8/16-bit version (ATmega and MSP430)

Test suite - 32-bit version (ARM and ESP8266)

Test suite - Floating point (ARM and ESP8266)
