Meta key in PicoLisp program

[Thorsten Jolitz]

Hi List, 

how would I write a 
- Meta/Alt key
- AltGr key

in a PicoLisp program?

E.g. if I want to write 
AltV (M-V or M-S-v in Emacs)
CtrlALTV (C-M-V or C-M-S-v in Emacs)

instead of something like this (CtrlV):

,---
| (^V (insChar (key)))
`---

cheers,
Thorsten

bug in daemon?

[Axel Svensson]

Hi!

I noticed the 'daemon function does a fine job distinguishing builtin
C functions from lisp functions. However, it redefines the function to
evaluate all arguments, rather than letting the function decide for
itself. Here is an example transcript:

: (setq a 3)
- 3
: (while (gt0 (dec 'a)) (prinl @))
2
1
- 1
: (daemon 'while (prinl while called))
- (@ (prinl while called) (pass $268284695))
: (setq a 3)
- 3
: (while (gt0 (dec 'a)) (prinl @))
3
while called
# infinite loop

Hi Thorsten,

 AltV (M-V or M-S-v in Emacs)
 CtrlALTV (C-M-V or C-M-S-v in Emacs)
 
 instead of something like this (CtrlV):

Unfortunately, this is not directly possible.

Alt/Meta key combinations have no representation in ASCII or UTF-8.
Instead, they are generated as events by the runtime system, where key
events may have certain bits set for modifier keys.

As such, they are very system-dependent. External libraries like
'termcap/terminfo' or 'curses' can be used to handle them.

BTW, this is one of the reasons why the PicoLisp line editor uses a
'vi'-style user interface. It needs only ASCII-keys.

Cheers,
- Alex
