Updates: Status: Accepted Labels: Type-Defect Priority-Low Component-Contrib Usability Comment #4 on issue 343 by gwern0: XMonad.Prompt.RunOrRaise doesnt always detect an already running program http://code.google.com/p/xmonad/issues/detail?id=343 OK, I think I sort of see the problem. You specified you are using the Prompt module, right, not the raw WindowGo/runOrRaise code. The Prompt module has a line like
isApp :: String -> Query Bool isApp "firefox" = className =? "Firefox-bin" <||> className =? "Firefox"
Your Firefoxes, though, say
WM_CLASS(STRING) = "Navigator", "Shiretoko"
Looking at the prompt, it runs
open :: String -> X () open path = io (isNormalFile path) >>= \b -> if b then spawn $ "xdg-open \"" ++ path ++ "\"" else uncurry runOrRaise . getTarget $ path
Now 'firefox' maps to no filepath or directory, so we fall through to the else. 'getTarget' runs on the argument 'firefox', and it is defined as:
getTarget x = (x,isApp x)
As we saw, 'isApp' is defined incorrectly, so it will fail and return Query False, which will make 'runOrRaise' shrug and just execute whatever program is named 'firefox'. Firefox however is smart enough to know it's already running, and will just open a new window or tab, rather than a whole new browser. So, that's what's wrong. The solution probably involves something like 'raiseBrowser' and the 'raiseVar' code in WindowGo & ShellPrompt, but I'll let Justin decide what is the best solution. (The obvious quick hack is to make isApp accept Navigator and Shiretoko as strings matching apps. But the whole isApp idea is bad.) -- You received this message because you are listed in the owner or CC fields of this issue, or because you starred this issue.
