Bundling GTK3 apps

Use this to bundle a simple GTK app:

#!/bin/bash

function make_dirs {
  mkdir -p "${1}"/"${1}.AppDir" || echo ""
}

function extract_rpms {
  FILES=$(find ../ -name *rpm)
  for FILE in $FILES ; do
    rpm2cpio "${FILE}" | cpio -i --make-directories
  done
}

function copy_desktop {
  find . -name *desktop -exec cp {} . \;
}

function make_apprun_skel {
cat > ./AppRun <<\EOF
#!/bin/sh
HERE=$(dirname $(readlink -f "${0}"))
echo "${HERE}"
export PATH="${HERE}/usr/bin/":$PATH
export LD_LIBRARY_PATH="${HERE}/usr/lib/":$LD_LIBRARY_PATH
cd "${HERE}/usr"
EOF
chmod a+x ./AppRun
}

function patch_usr {
  find . -type f -exec sed -i -e 's|/usr|././|g' {} \;
}

function get_assistant {
  wget -c "https://downloads.sourceforge.net/project/portable/64bit/AppImageAssistant%200.9.3-64bit"
  chmod a+x ./AppImageAssistant*
}

function make_appdir {
  ./AppImageAssistant* "${1}.AppDir" "${1}.AppImage"
}

APPNAME=Transmission
make_dirs "${APPNAME}"
cd "${APPNAME}"
wget -c -r -l1 -np "http://dl.fedoraproject.org/pub/epel/beta/7/x86_64/" -A transmission-*.rpm -P download
find ./download/ -name *qt* -exec rm {} \;
cd "${APPNAME}.AppDir"
extract_rpms
patch_usr
copy_desktop
make_apprun_skel
echo "./bin/transmission-gtk $@" >> AppRun
cd -
get_assistant
make_appdir "${APPNAME}"

The following is likely outdated.

Pitivi uses the following AppRun script to run a bundle consisting of Pitivi and the entire GTK stack:
