Reworked main documentation page
Hi all, I reworked the main doc page a bit: - bit more stylish (smaller font headers) - consistent grouping - moved a few links to the now separate examples page - and v.v. Also I intend to continue to rework pages. My todo's for near future are: - rework the frontpage of the Wiki, where I'll put the essence of the textual content of Tractatus Blaesicus - rework Tractatus Blaesicus itself to a nice(r) demo - create useful reference docs to the libraries Best, Arie

Fascinating the amount of accessories there are for the RP... JC -- UNSUBSCRIBE: mailto:picolisp@software-lab.de?subject=Unsubscribe

Yes, the examples are a bit meaningless as they are now.

Concerning stdinread: You need an (in NIL ..), because when the script runs, the
*current* input channel is still the script itself (this is the nature of a Lisp
interpreter). So if you write
#!/usr/bin/picolisp /usr/lib/picolisp/lib.l
(in NIL
(println "Type a few lines and end with ctrl+d")
(setq Var (in NIL (till NIL T)))
(prinl Var)
(println "Program is finished!") )
(bye)
and then do
$ { echo abc; echo def; } | ./stdinread
"Type a few lines and end with ctrl+d"
abc
def
"Program is finished!"
Note that starting ./stdinread and then typing works but will not print any
output, because ^D terminates the interpreter.
The other examples are fine, aren't they?

Re: PLEAC last part finished (File Access)
OK. I changed that to an example using redirection of STDIN to a file. 2018-06-16 15:56 GMT+02:00 Arie van Wingerden : > Or do you mean e.g. something line: > ./script ?? > > Thx. > > 2018-06-16 15:38 GMT+02:00 Arie van Wingerden : > >> Hi Alex, >> >> please have a look. >> >> I am still not very sure about the read STDIN until EOF. >> >> I created a small script, but when is EOF of STDIN really signalled??? >> >> Maybe a small example? >> >> Thx, >>Arie >> > >

PLEAC last part finished (File Access)
Hi Alex, please have a look. I am still not very sure about the read STDIN until EOF. I created a small script, but when is EOF of STDIN really signalled??? Maybe a small example? Thx, Arie

?? What is wrong?
You mean this example?
: (make
(find
'((C) (or (sp? C) (nil (link C
(chop "abcd efg")))
-> ("a" "b" "c" "d")
It seems that this works OK?
Please explain!

Ah. OK! Well, I won't bother myself then to dive into the rest.
At least we've saved them from possible extinction :)

Question on PLEAC example
Hi Alex, just started on chapter 7. You give this code as an example. # Read STDIN till EOF : (setq Var (in NIL (till NIL T))) This is a line a peaceful line it is not drunk it drinks no wine # Here I pressed ctrl+d which forces PicoLisp to end As discussed earlier you cannot simulate an EOF from STDIN. So, why then such example. It seems not useful at all... Please comment :) Thx, Arie
Re: picolisp at last ?
JC: wasn't your goal to use PicoLisp 64-bit? ;) I'm actually using a ROCK64 (arm64) daily, and of course run PicoLisp 64-bit on here. In terms of specs, it's **much** better than RPi3, but support is... I also have an RPi2, and can power it from the MacBook but there's always a spinning rainbow in the top left corner of the display (low power). If you're not connecting external USB disks, it should be fine.

The appropriate version of Raspian does have picolisp :) Ok, after dusting off the unit and installing the latest raspbian, I managed to install picolisp, but not the most recent version, for that I need to reconfigure the keymap so that I can type properly with that usb Japanese keyboard :) Once I get the most recent repositories referenced, I'll have 1.7.. Then configure ssh and I'll be able to run the thing directly connected to the router. Pretty exciting :) I'm even wondering if I can't power the thing directly from the MacBookPro's usb port...
