multithreaded uLisp

10

I had another idea that would require editing the uLisp source (i.e. not an extension): making the multithreading feature of the esp32's FreeRTOS available to uLisp. I wish it was...

ESP32 Arduino core gives less available RAM on ESP32-S2

3

I tested the latest release of uLisp on an ESP32-S2 board (Adafruit ESP32-S2 Feather) with the current Arduino core, 2.0.9, and found I have over 8Kbytes less available RAM than...

using esp32 sleep function

2

Right now the `(sleep)` function doesn't actually put the CPU to sleep, it just burns time in a delay() loop. However, the ESP32 does have a light-sleep function that preserves...

Any suggestions for how to solve compiler warnings in uLisp 4.4?

5

The new error-handling functions in uLisp 4.4, **unwind-protect**, **ignore-errors**, and **error** work correctly, but cause compiler warnings on all platforms: ````text /Users/david/Documents/Arduino/LispESP198/LispESP198.ino: In function 'object* sp_unwindprotect(object*, object*)': /Users/david/Documents/Arduino/LispESP198/LispESP198.ino:4031:11: warning: variable...

opaque types

I had another idea: user-definable opaque types. You could add a `void*` pointer to the car and cdr of the object union, and then have a variable `OpaqueCounter` which is...

websockets?

4

I found an Arduino websockets library that works with the existing wifi library: https://github.com/gilmaimon/ArduinoWebsockets It seems simple enough to implement similar websocket functions as the existing wifi functions in uLisp,...

very simple keyword support

4

earlier I think I mentioned that I implemented generic keywords by automatically wrapping them in `(quote)` in the reader, but that's probably a bad solution if I ever implement macros....
