* Is there a way to spawn processes from the XWin login shell? @ 2013-03-23 0:02 Thiago Padilha 2013-03-27 15:52 ` Thiago Padilha 0 siblings, 1 reply; 4+ messages in thread From: Thiago Padilha @ 2013-03-23 0:02 UTC (permalink / raw) To: cygwin-xfree XWin uses a login shell to configure its environment when it starts up, and processes spawned from the tray icon inherit XWin environment so they don't have to be spawned from login shells. Is there a way to achieve the same effect without using a tray icon? For example, can I have a desktop shortcut that launches a terminal emulator with a simple interactive(non-login) shell and still have it inherit the currently running XWin environment like it was started from the tray icon? -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://x.cygwin.com/docs/ FAQ: http://x.cygwin.com/docs/faq/ ^ permalink raw reply [flat|nested] 4+ messages in thread

Still, the only way to start processes inheriting from the login shell seems to be by using the tray icon. It would be nice to have a startxwin flag that did that, eg: startxwin -command 'urxvtc -e zsh' # instead of starting a new xwin instance, this would send a command to be spawned by the running login shell which would have the same effect as select a .XWinrc menu entry with the following 'urxvtc -e zsh' On Fri, Mar 22, 2013 at 9:02 PM, Thiago Padilha <tpadilha84@gmail.com> wrote: > XWin uses a login shell to configure its environment when it starts > up, and processes spawned from the tray icon inherit XWin environment > so they don't have to be spawned from login shells.

To inherit implies that it is a child of XWin, so no. However, you can create a process with an identical login environment by requesting the shell to create a login environment.

The login environment is nothing to do with startxwin. You are requesting zsh to create the login environment with the '-l' flag. -- Jon TURNEY Volunteer Cygwin/X X Server maintainer -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://x.cygwin.com/docs/ FAQ: http://x.cygwin.com/docs/faq/ ^ permalink raw reply [flat|nested] 4+ messages in thread

It would have been simpler if I asked: 'can I make XWin start child processes without using the tray icon?' :) The reason I was trying to do that is because my zsh login scripts set things that only make sense once in a traditional XServer lifetime(setxkbmap,xmodmap,ssh-agent), not to mention xmodmap complains the second time it is ran. I managed to refactor the scripts so they can be run many times in the same x-server so everything is fine now. In any case, you should consider implementing a flag to XWin.exe so it can spawn processes in an already running instance of XWin.exe, as this would bring XWin more close to the spirit of traditional X window managers where a login environment is only created once per session. Anyway, thanks for your help Jon On Wed, Mar 27, 2013 at 1:41 PM, Jon TURNEY <jon.turney@dronecode.org.uk> wrote: > On 23/03/2013 00:02, Thiago Padilha wrote: >> XWin uses a login shell to configure its environment when it starts >> up, and processes spawned from the tray icon inherit XWin environment >> so they don't have to be spawned from login shells.
