i am not talking about dbus-launch but any program out there that could make use of this technique. that program may not even have been written. all we can assume pretty much is that the output will be sh or csh compatible. > >and for that reason i don't want to play games with regexps but am > >hoping there is a way to come up with a more reliable solution. > How else, if not with regexps? the only way that will be 100% reliable is to implement a full posix compatible parser. this of course is way to much for fish, however, this parser would not need to be part of fish. it could be an external program. all that is really needed is a a way to change a fish environment using an sh script. perhaps this can be done by running the script in plain sh, and then examining the resulting environment within that sh process, and copy the changes over to the fish environment. sh-eval: #!/bin/sh eval $* fish -c set #--- the above wrapped into a function that does the equivalent of: making a snapshot of the environment. run sh-eval comparing the previously saved environment with the output produced by the script. setting the changed variables in the outer environment. unless i miss something, this should cover most cases while avoiding the need to parse sh syntax. greetings, martin. -- cooperative communication with sTeam - caudium, pike, roxen and unix offering: programming, training and administration - anywhere in the world -- pike programmer travelling and working in europe open-steam.org unix system- bahai.or.at iaeste.(tuwien.ac|or).at administrator (caudium|gotpike).org is.schon.org Martin Bähr http://www.iaeste.or.at/~mbaehr/ ------------------------------------------------------------------------- Take Surveys.
