  6. Shell command/script for cleaning out /usr/portage/distfiles

    in General Discussion

    Posted

    Does anyone have a shell command or script that will delete *.tar.foo files out of /usr/portage/distfiles with the exception of those that relate to currently merged packages?

     

    Such a command would be fantastic for recovering storage space while at the same time avoiding the repeated downloading of existing packages (for example, when a USE flag is changed).

     

    eclean -d distfiles

    Does the job for me.

  7. how to write bash completion modules

    in General Discussion

    Posted

    I would like to learn to write bash completion modules. The available documentation is poor. So i would like to get help writing completion for cpupower. I already have completion for first argument working. Next i would like to get completion for -g <governor> working. Please reply if you can help me :-).

     

    Here is what i have already:

    /usr/share/bash-completion/completions/cpupower

     

    _cpupower() {
    # pointer to current and prev completion word
    local cur prev
    # completion options
    local opts

    # array storing the possible completions
    COMPREPLY=()

    # define cur and prev
    cur="${COMP_WORDS[COMP_CWORD]}"
    prev="${COMP_WORDS[COMP_CWORD-1]}"

    opts="frequency-info frequency-set idle-info idle-set set info monitor help"

    COMPREPLY=( $(compgen -W "${opts}" -- ${cur}) )
}

complete -F _cpupower cpupower

  8. Evdev ebuild that supports wheel emulation for new trackpoints with clickpad

    in General Discussion

    Posted

    this isn't covered by synaptics?  https://wiki.gentoo.org/wiki/Synaptics <--- eh?

    Evdev has option "EmulateWheelButton" to emulate mouse wheel when middle button is pressed. It doesn't work on new thinkpads where trackpoint buttons are integrated to touchpad because synaptics and evdev are two different drivers and can't communicate.

     

    Here is the related bug report:

    https://bugs.freedesktop.org/show_bug.cgi?id=70780

     

    Picture of new thinkpad trackpoint:

    I got it fixed with:

    src_configure(){
        python_foreach_impl cmake-utils_src_configure
}

     

    But now it fails like this:

  11. Could NOT find PythonLibs (missing: PYTHON_LIBRARIES PYTHON_INCLUDE_DIRS)

    in Portage Help

    Posted

    I'm trying to write ebuild for screencloud[1]. I have already dependencies solved and with source the configuration succeeds:

     

    Found PythonLibs: /usr/lib64/libpython2.7.so (found version "2.7.8")

     

    While emerging the ebuild i get this error:

     

    CMake Error at /usr/share/cmake/Modules/FindPackageHandleStandardArgs.cmake:136 (message):
  Could NOT find PythonLibs (missing: PYTHON_LIBRARIES PYTHON_INCLUDE_DIRS)

  /usr/share/cmake/Modules/FindPythonLibs.cmake:210 (FIND_PACKAGE_HANDLE_STANDARD_ARGS)
  CMakeLists.txt:222 (find_package)

     

    Here is the current ebuild:

  17. smdev guide (eudev alternative)

    in General Discussion

    Posted

    Smdev

    Smdev is simple device manager. It's alternative to udev, eudev and mdev. I maintain smdev ebuilds on my overlay[1]. I have working keyboard, mouse, touchpad, trackpoint, sound, graphics, wifi, hotplug and module autoloading with the default config and initscript that comes with the ebuild.

     

    [1] https://github.com/causes-/causelay/blob/master/sys-fs/smdev/smdev-0.2.2.ebuild

     

    Migrate guide from eudev

    Here is migrate guide away from eudev.

     

    First you need to disable udev and gudev use flags.

    /etc/portage/make.conf

    USE="$USE -udev -gudev"

     

    Then enable keyboard, mouse and synaptics INPUT_DEVICES instead of evdev.

    /etc/portage/make.conf

    INPUT_DEVICES="keyboard mouse synaptics"

     

    Rebuild world.

    # emerge -uavDN @world

    # emerge -av --depclean

     

    Configure X.Org to use keyboard/kbd, mouse and synaptics instead of evdev. Use "InputDevice" instead of "InputClass".

    /etc/X11/xorg.conf.d/30-keyboard.conf

    Section "InputDevice"
            Identifier "keyboard0"
            Driver "kbd"
            option "AutoServerLayout" "on"
            Option "XkbLayout" "fi"
    EndSection
     

    /etc/X11/xorg.conf.d/40-touchpad.conf
    Section "InputDevice"
            Identifier "touchpad0"
            Driver "synaptics"
            option "AutoServerLayout" "on"

            Option "HorizTwoFingerScroll" "1"
            Option "VertTwoFingerScroll" "1"

            Option "SoftButtonAreas" "65% 0 0 20% 45% 60% 0 20%"
            Option "AreaTopEdge" "20%"
    EndSection
     

    /etc/X11/xorg.conf.d/50-mouse.conf
    Section "InputDevice"
            identifier "Mouse0"
            driver "mouse"
            option "AutoServerLayout" "on"
            option "device" "/dev/input/mice"
    EndSection

     

    Add smdev to sysinit runlevel.

    rc-update del udev sysinit
    rc-update del udev-mount sysinit
    rc-update del udev-postmount boot
    rc-update add smdev sysinit

     

    Now you are ready to reboot.
