No

I'm using mt branch of menu-cache but this bug is present in v. 3 too.

I have Icewm and Xfce here. 'Applications' directory in pcmanfm displays properly the apps according with the environment I boot into but it fails to acknowledge the NotShowIn key. So desktop files I have that have 'NotShowIn=XFCE;' still show up in the Applications directory of pcmanfm in Xfce.

    It works for me. The issue may be that you haven't set the environment variable XDG_CURRENT_DESKTOP to some appropriate value ("XFCE" in your case) before you start pcmanfm. If you don't have it set then both ShowOnlyIn and NotShowIn values will be ignored. If you have it set to wrong value then that value will be checked in ShowOnlyIn and NotShowIn instead of what you want. Check it, please.
    Thank you very much.

    $ env|grep -i desktop
    XDG_SESSION_PATH=/org/freedesktop/DisplayManager/Session0
    XDG_SEAT_PATH=/org/freedesktop/DisplayManager/Seat0
    DESKTOP_SESSION=xfce

    So maybe it should check DESKTOP_SESSION variable (that's the way it works here)?

    Andriy, are you going to work on this? (asking because of the 'Works For Me' resolution)
    Here's for IceWM in Fedora:
    $ env|grep -i desktop
    XDG_SESSION_PATH=/org/freedesktop/DisplayManager/Session0
    XDG_SEAT_PATH=/org/freedesktop/DisplayManager/Seat0
    DESKTOP_SESSION=icewm

    So the way the desktop session is setup here is with the DESKTOP_SESSION variable.
    Just want to know because for me it looks like a menu-cache issue but if you say the bug is somewhere else then I report there.

    The problem isn't the desktop session. menu-cache works with OnlyShowIn but fails with NotShowIn.

    OnlyShowIn=XFCE highlighted: http://ompldr.org/vZ2M3dw

    NotShowIn=XFCE failed: http://ompldr.org/vZ2M3eg

    I'm no programmer but I looked for 'ShowIn' in the menu-cache code and I saw some stuff that looks like pretty old as was only for GNOME.

    Note that the XDG specification says that OnlyShowIn and NotShowIn should be never specified in the same file. If you have them both then NotShowIn will be ignored. Unfortunately, that's unavoidable due to specification:
    http://standards.freedesktop.org/desktop-entry-spec/latest/ar01s05.html

    Your assumption that DESKTOP_SESSION variable should be honored by applications that use menu is wrong. That variable is user-specific and specifies which selection was made in display manager. Just read available documentation on that variable usage. To make assumption based on that is completely wrong (it may contain values 'default', 'gnome+openbox' and so on) and PITA.

    Moreover, decision what desktop environment is used, isn't in menu-cache but in application. You may open a bug for lxpanel or pcmanfm but I believe both will be rejected for reason that I explain below. Since we have LXDE standard-compliant, we use XDG specifications here. XDG standard specifies variables that are prefixed with XDG_ and the variable which defines the desktop environment is de-facto XDG_CURRENT_DESKTOP. If that variable isn't set then applications assume the desktop is unspecified. Pcmanfm ignores both OnlyShowIn and NotShowIn in that case, and lxpanel shows all items that are available either in GNOME, KDE, XFCE, or LXDE - i.e. you should add all of them into NotShowIn to remove from menu of lxpanel in such case.

    So I think you should just correctly set XDG_CURRENT_DESKTOP variable (case isn't ignored so you should have it exactly as in OnlyShowIn or NotShowIn lines, i.e. "XFCE") and you'll get your desired result.

    I hope that explanation helps.
    Thank you.
