[Java-readline-devel] run on linux -- hung gnu readline, modified getline

[Robert A. <ra...@pp...>]

I have had problems with using the gnu readline with jython under linux 
systems.  It would work fine except when the window was resized and then 
everything would hang and I would have to exit with Control-C causing a 
JavaVM panic in native code type of exit.  This is with various linux 
distributions though all of them were gcc 2.9X based.

Because of this problem and the distribution incompatibility of gnu readline 
with jython, I tried getline.  The compile went ok but testing and usage 
revealed the arrow keys would print out 'A','D',... This was under KDE 
Konsole terminal.  From experimentation and debugging if I made the following 
changes,
 modified src/native/Makefile: add unix symbol
  CFLAGS=-fPIC -DPOSIX -Dunix
  CC = gcc -g

 modified src/native/getline.c: add c=='O' option
	      case '\033':				/* ansi arrow keys */
		c = gl_getc();
		if (c == '['||c=='O') {

then it worked fine.  I am not too familiar with unix terminal i/o.  Do these 
seem like reasonable changes for getline or any hint as to what might be 
going on?

thanks,
