Sending a region to another X application

Sending a region to another X application

[H. Dieter Wilhelm]

Hello (),

I've written a major mode (https://code.google.com/p/ansys-mode/) for an
obscure programming language (APDL
http://www.ansys.com/Support/Training+Center/Courses/Introduction+to+ANSYS+Mechanical+APDL)
which is used to automate finite element simulations.

At the moment the user is "copy and pasting" code snippets from an Emacs
buffer to the TCL/TK application's "command" text field.  The Emacs mode
would be more helpful if one could directly "send" code fragments with a
key binding to the application.

I've no experience with GUI programming and the only idea I've got from
internet investigations, so far, is to utilise an external C program for
sending the data over the X server with the help of libraries like Xlib
or XCB, but there seems to be little documentation.  Do you have a
better idea or is this the easiest way to go?

Dieter,

This is more of a general programming question than an emacs one, so you 
might want to target me off list if you have follow-up questions. Having 
some experience with TCL, I know that often a command shell is just a 
TCL shell with functions defined for the commands you execute. If you 
have such a situation, you can extend that shell with some code that can 
accept commands from a network connection, pipe, or even via the X 
clipboard. If you have created a major mode in emacs, you know enough to 
know that you can talk to these communication channels from emacs lisp 
without too much work. Extending the TCL shell is your major task.

As for using X-Window, I've not heard of such a thing done for 
inter-application communication, but I suppose it is possible. You want 
to generate X events for the keystrokes. It would take some work, so 
think books when you are looking for documentation. Maybe some open 
source GUI testing program could give you some pointers. I wouldn't 
choose to go this route, however.

Search these words: serialization in emacs lisp
and you will find some libraries/packages that can handle this for you.
