This may be the first message on the mailing list? It is a message mostly composed of questions: I have ifeffit and atoms running just fine on MacOS X, thanks to Francois' hard work figuring some things out and Matt's quick port of ifeffit. 1. Does anyone have Athena running? 2. Is anyone able to run ifeffit from Terminal.app, as opposed to running it from an xterm? When I try this, I get an error message, "PGPLOT /xw: cannot connect to X server". When I do ps -aux | grep pgp I see a process charlesb 3239 0.0 0.1 67316 672 std- S 0:00.04 /sw/pgplot/pgxwin_server -display :0.0 so clearly I need to something to tell terminal.app about the pgplot server? Anyone have advice on this? I just don't know where to look beyond this point. Why do I care about this distinction? (1) Terminal.app supports cut/copy/paste, (2) terminal.app is scriptable, which means that you can define define macros, or use script menu to put in common command blocks. In principle, this means that you could use Applescript studio to control ifeffit from a mac-native gui. 3. Has anyone run ifeffit using aquaterm? I'm very heartened by the recent rapid progress and hope that it can continue.
