froth
is a Forth implementation for R. If you’re new to
froth
or Forth, check out the detailed
overview or my in-depth
tutorial.
froth
is distributed by CRAN. You can download it for
your R installation by running:
install.packages("froth")
This implementation comes with a number of differences from other FORTHs:
3 2 /
returns
1.5
print
methods; use .R
to format
according to the print method for the top of the parameter stack'
will always look for the next token, not the next
token from input stream. This makes it identical to [']
in
function definitions. I may change this later.This will (likely) not be a 1:1 copy of Gforth, I think I’d rather have a forth implementation that is robust and works in R than one that exactly imitates existing Gforth. But…tbd.
