Wow.  That's quite the shell script.

Try replacing read with sed 1q in your shell
definitions.  You're in uncharted territory.
Read and acme don't get along very well
about reading multibyte UTF sequences.
Acme currently assumes that it doesn't have to deal
with programs that read from data 1 byte at a time,
like read does.

I hope it can be made more simple. Keep in mind it's my first attempt
at programming acme from rc :-) (having no experience with the acme
interface, doing the same in C seemed even more scary to me). The hope
was that it might be used as an example, to built upon... (oh well :-)

Last night I played with it at home, and when it was obvious that
the selection was made correctly, I looked at the reading part,
tried cat and then sed 1q and it worked.
Thanks for the hint, and for explaining the problem!

[9fans] finding acme window id from shell script?

[Axel Belinfante]

Another question about programming acme from rc:
Can a shell script (or other program) find
out from which acme window it was invoked
(other than looking for a 'known' filename
 in/mnt/acme/index)?

In the manual I only found acme's ID command,
which I cannot use from within the shell script
(or is there a way?), and reading the ctl file,
but I assume that refers to e.g. /mnt/acme/<nr>/ctl
and to read that I already need to know <nr>.
Currently I just look for a 'fixed' filename in
/mnt/acme/index, which works ok; I'm just wondering
whether there is a more 'direct' way.

Thanks,
Axel.

[9fans] 'euro symbol' special in acme interface?

[Axel Belinfante]

Today I tried to update the coffeelist script I mentioned sometime
before, such that the 'field name' 'payable' is replaced by the euro
sign (made using 'compose' e$ ).
However, when I read that substring from acme, so, when reading from the
data file after making the selection with a regexp, I seem to get
the empty string. Making the selection seems to work OK;
using mouse button 3 on the string I use to make the selection
(prefixed with a :) works ok.
Anything obvious that I may have missed?
