flash vs ram usage

[hugows]

hi yesco, great project, i'm eager to try it at home! since the cheap dev boards available have relatively big flash, i'd like to understand the usage of flash vs ram in the context of esp-lisp, like: is esp-lisp stored on the flash? could we run a lisp program stored in the flash? etc... thanks!

Hi. Lisp currently not stored in flash.

I'm experimenting with making that possible.

The biggest issue with making so is symbol names, as having flash point to RAM would-be a bad idea....

But also, one doesn't want force all symbols to be defined/require flash for normal programs.

I have some solutions in the pipeline.

The esp-lisp is designed to be more efficient in memory usage compared to other lisps/lua/js

For example small simple symbol names aren't "stored" at all but instead encoded in the pointer:

1. Three any characters
2. Six characters a-z

Such lisp code would pose no problems. On Jul 7, 2016 01:22, "Hugo Schmitt" [email protected] wrote:
