definitions:: 'cuecat' is a barcode reader
'expect' is a scripting language that lets you
automate
actions with interactive programs such as
'ftp'
or 'telnet'.
what i am trying to do::
1 translate cuecat data(done via larry wall's perl script- don't
have URL).
2 write data to an interactive program.
this last is giving me fits. possible ways::
write data to file. slurp up file with an expect script. this
script needs to be constantly running- logging in to the
system i use is a pain otherwise. i do not yet know how
to slurp the data with expect.
pipe or write data to said expect script directly from the perl
script instead of writing the data first to a file. i do not know
how to do that kind of inter-process communication.
use the (an?) expect module for perl- i know of one,
but the syntax looks darn right scary to me and i already
have a sense of expect- so i'd rather not learn the perl
version :P. However, learning the perl version removes
the need for inter-process communications. as long as i can
preprocess the keyboard (or cuecat) input, then send it to the
interactive program (telnet session) i should be fine.
the questions are::
1) has anyone had experience with this kind of project?
2) which of the above would be the most likely path for
me to follow?
3) any alternate methods?
thanks,
willy :)
