Yes sorry.

And I plan to make an even smaller version!

Glad to see you are interested.
Two others, but I understand that mini could have severe limitations that
would prevent a fix:
1) «seed» only accepts numbers in mini,
2) «in» doesn't support negative numbers in mini.

I'll keep you updated if I find some more.

Don't appear in *mini*, you mean? Well, yes, it is "mini" after all ;) And many
features of real PicoLisp will not work anyway.

Yes, 'format' was changed with picoLisp-3.0.3 in 2010 to accept also lists of
characters. Probably I forgot (or had problems?) to port this change to mini. So
the 'pack' is not necessary in PicoLisp any more, but still in miniPicoLisp.

Thanks! I put 'format' in mini into my todo list :)

Discrepancies in lib/misc.l between picoLisp and miniPicoLisp

[Christophe Gragnic]

Hi,

Trying to port tests to miniPicoLisp I needed to copy some
definitions from lib/misc.l from pico to mini, and this is what I found:

1) Many definitions don't appear in pico. Is it intented ? If so, why ?

2) Discrepancy in the $dat implementation:

mini
(format (pack (car S)))# Year
(or (format (pack (cadr S))) 0)# Month
(or (format (pack (caddr S))) 0) ) )   # Day

pico
(format (car S))   # Year
(or (format (cadr S)) 0)   # Month
(or (format (caddr S)) 0) ) )  # Day

Tests of $dat written for picoLisp don't pass without the pack in miniPicoLisp.
That's because the format function in mini doesn't accept lists.
Just to mention my findings. It may be intented for the sake of
simplicity of mini.
