Hi list, I'm looking for help on doing something VERY un-smalltalkish with Pharo... let me explain. I am working on several variants of this way of controlling external programs with Emacs:
http://angg.twu.net/LATEX/2021emacsconf.pdf The slides - link above - are the best way to understand how it works, but there's mode info here: http://angg.twu.net/emacsconf2021.html The method above only works with programs that have REPLs that can be run in terminals, but I have some variants of it that let me send commands - single-line or multi-line - to external programs that only have GUIs. In one of these variant the external program listens to the signals SIGUSR1s and SIGUSR2s, and initially what it does when it receives these signals is: on SIGUSR1: print the contents of the file /tmp/bridge-data on SIGUSR2: eval the contents of the file /tmp/bridge-data The action of SIGUSR2 can be used to redefine the action fo SIGUSR1. There is a demo for Tcl here: http://angg.twu.net/IMAGES/2021-emacs-tcl-bridge.png http://angg.twu.net/e/tcl.e.html#2021-emacs-tcl-bridge How can I implement something similar in Pharo? I mean, how do I make it react to SIGUSR1s by printing - in any sense - the contents of /tmp/bridge-data, and react to SIGUSR2s by eval-ing the contents of /tmp/bridge-data? Thanks in advance! =) Eduardo Ochs http://angg.twu.net/#eev
