I'm working with the readline module, and I'm trying to set a key combination to process the current command line by calling a known function, *and* enter the command line.
Something along the lines of: * execute function spam() in some context where it can access the current command line as a string * enter the command line Function spam() may or may not modify the command line. Here is what I have got so far: I can discard the current line and call a function: readline.parse_and_bind(r'"\C-p": "%cspam()\n"' % 0x15) # ^U binds ctrl-P to the key combinations `ctrl-U spam() Enter`, which clears the command line before entering spam(). If I leave out the ctrl-U, I'll get a SyntaxError or other exception, e.g. command line `x = 123` gets transformed into `x = 123spam()`. This is not suitable: readline.parse_and_bind(r'"\C-p": "; spam()\n"') because it changes the command line. It's okay for spam() itself to modify the command line, but the key binding should not. I tried to do this: readline.parse_and_bind(r'"\C-p": "\nspam()\n"') but it gives me a segmentation fault, which is a little less helpful than I had expected. This Stackoverflow question suggests that what I want is not possible in vanilla Python: http://stackoverflow.com/questions/11680356 but I'm a stubborn guy and I have not given up yet. Any suggestions? (P.S. I'm aware of IPython, I want to get this working in the standard CPython interpreter.) -- Steven -- http://mail.python.org/mailman/listinfo/python-list
