Hello,
I tried to modify Russ' script below to be usable on p9p. I came up with
------------------------------------
#!/usr/local/plan9/bin/rc
if(! ~ $#* 1) {
echo 'usage: Run title' >[1=2]
exit 1
}
id=`{awk -v 'pat='$1 '$6 ~ pat {print $1}' <{9p read acme/index}}
if(~ $#id 0) {
echo 'no match for pattern' >[1=2]
exit 2
}
if(! ~ $#id 1) {
echo 'ambiguous pattern' >[1=2]
exit 3
}
if(~ `{wc -w <{9p read acme/$id/rdsel}} 0) {
echo 'no command selected' >[1=2]
exit 4
}
#exec cat <{9p read acme/$id/rdsel}
exec /usr/local/plan9/bin/rc <{9p read acme/$id/rdsel}
------------------------------------
but the last line doesn't really do what I want, yielding the error:
Run: exit 1
rc: /dev/fd/5:2: token EOF: syntax error
can anybody help me with what is wrong?
The commented-out line with cat prints correctly what I have
selected in the other window (see the description of the original
script), e.g.
awk '{print $2}'
Thank you!

Post by Rudolf Sykora1) I usually have a special window in which I have many commands. I
then select the one needed and chord it to the appropriate window
(i.e. I don't use the whole contents of a window).
2) sometimes I have more such windows.
This is an interesting usage model. I've never seen it before.
The power of acme is that you can extend it with external
programs. The script below implements this usage; I called it Run.
You can type and select your command in one window, with a name matching
pattern, and then in the other window's tag execute >Run pattern.
Run finds the window with a title matching pattern, pulls out the
selected text, and runs it through rc.
See http://swtch.com/~rsc/acme-Run.png for an illustration.
