Yes, this is the common problem. I tried to explain it in the article, perhaps
it got a bit too short:

   For Debian, however, I had to install libncurses5, and set a symbolic link
   (for reasons I don't really understand):

  $ sudo apt-get install libncurses5
  $ (cd /lib/x86_64-linux-gnu; sudo ln -s libncursesw.so.5.9 libncurses.so)

   It seems that other Linux distributions need similar actions. Good luck!

So it is important that you set the symbolic link!

(For some reasons, the default "libncurses.so" is NOT a shared object library
which can be called from C programs, but a text file with some kind of pointer
or link in it)

If you are only interested in a boolean result, but don't need the values
of '@A' and '@B', you could of course simply do

   (sub? Varstring ...)

Re: Vip Editor

[David Bloom]

Thank you Alex for another exciting utility as well as more example code to
learn from.  I'm having some difficulty installing vip and I hope someone
can help me out.  Using a 64-bit Netrunner (based off of Manjaro based off
Arch) install, a fresh 16-12 picolisp installation, and ncurses installed I
get:

$ sudo pacman -Ss curses|grep installed
core/ncurses 6.0+20161203-1 [installed]
multilib/lib32-ncurses 6.0-2 [installed]

$ vip testo.l
[/usr/local/bin/vip:10] !? (265391 $10060141011 $10060141013
$10060141015)
[DLL] /usr/lib/libncurses.so: file too short
? ^
-> (265391 $10060141011 $10060141013 $10060141015)
?

What does it mean that mean the file is too short?  Thanks and happy new
year!

Kind regards,
David

Re: pil64 on Android/Termux

[Erik Gustafson]

False alarm. A bit of research showed I needed to force a fresh install of
Termux to get access to 64-bit packages, even though the app was already up
to date.

pil64 is a go!

Re: pil64 on Android/Termux

[Erik Gustafson]

Hi Alex,

It is very easy. Just install the Termux App, then do

   $ apt update
   $ apt install picolisp


Hmm, that leaves me with pil32.

   : (version)
   16.12.22 C
   -> (16 12 22)

   : *CPU
   -> NIL

I've been using pil32 for awhile now, so I did

   $ apt purge picolisp
   $ apt update
   $ apt install picolisp

to make sure it wasn't just upgrading the existing install, but got the
same results.

Device is a Nexus 5x, which has a 64-bit ARMv8 processor.

Thoughts?

That's not necessary.

Re: matching a simple string variable

[Erik Gustafson]

Hi Joe,

Also note that it's fairly easy to pull in regex functionality, should you
need it.

See http://rosettacode.org/wiki/Regular_expressions#PicoLisp for an example
(pil64).

pil64 on Android/Termux

[Erik Gustafson]

Hi Alex,

What's the current process to get pil64 running on Android/Termux? I tried
the method from the original announcement (wget, dpkg, etc) with more
recent versions of PL to no avail.

Thanks in advance,
Erik

BTW, better is perhaps

   (match (cons '@A (conc (chop Varstring) '(@B))) ...

because 'append' unnecessarily copies the list just built by 'chop'.
'conc' avoids that garbage. Not critical though ;)
