Changes in Version 2.9
Version 2.9 features improved versions of the mapping functions, and setq and setf. It also incorporates bug fixes affecting trace and return.
The AVR version adds support for the ATtiny3216 and ATmega4809 microcontrollers.
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.
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.
The uLisp sources provide the following compile options:
|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.|
|lisplibrary||disabled||Evaluates the Lisp definitions provided in the Lisp Library on reset.|
* Not applicable to the versions with floating point.
See Older versions.
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)
