Ruby and 3270 terminal emulation

Hi all,

Are there any 3270 screen scraping libraries out there for Ruby? And
do you have any suggestions on how to write one?

Dan

Some time ago when I needed to support 3270, I ended up using s3270 from ht=
tp://x3270.bgp.nu/ -- this provides a scripting access to 3270 protocol. Yo=
u send 3270 requests to its standard input and it spits info and screen dum=
ps to the standard output. In my TSC-ACT project at http://sourcef...
projects/tsc-act I have 3270 integration via s3270, however there's no offi=
cial release yet (no easy installation and documentation yet). You can see =
an example of how I interact with s3270 via IO::popen() in here: http://tsc=
-act.svn.sourceforge.net/viewvc/tsc-act/trunk/lib/tsc/session/s3270-stream.=
rb?revision=3D17&view=3Dmarkup

Please contact me off-list if you are interested in more details.

Gennady.

If your emulator is Attachmate Extra, it has a built in
macro language that can read the screen and type in
data. This language can be invoked from Ruby or from
the DOS-prompt with the command "ebrun".

Back in my mainframe days, I used the HLLAPI (aka WHLLPAI, aka
HLLAPI32) interface of the terminal emulators to interact with the
mainframe. Worked beautifully...

If you're interested, I'm willing to extract the low-level code from
my old projects.
