 |
|
Portage's new hook ability has meant a lot of bashrc files are now flying around. Obviously, it becomes pretty impossible to merge all these great ideas into a single bashrc, let alone apply updates if there's a new version or a bug fix.
This script is a bashrc file that allows you to break your bashrc into multiple files, and set the order in which the hooks are applied.
The bashrc files are stored in /etc/portage/bashrc.scripts and a symlink to it is made in /etc/portage/bashrc.d. I use symlinks so that you can enable and disable scripts as you want, as well as order them without having to rename the original modules.
I also provide a script (hook_handler) to allow you to install and uninstall these hooks easily.
So, if you have a bashrc, the first step is to make a /etc/portage/bashrc.scripts directory and move your bashrc into it, giving it an appopriate name (I'll use "mybashrc" as an example. Then put the following script into /etc/portage/bashrc, replacing anything that was there before.
Then you can either use the second script to install your old bashrc file like this:
| Code: | | hook_handler -I mybashrc |
or make the symlink yourself like:
| Code: | | ln -s /etc/portage/bashrc.scripts/mybashrc /etc/portage/bashrc.d/10-mybashrc |
Here's the replacement bashrc script:
| Code: | pre_pkg_setup() {
#echo In hook pre_pkg_setup
for portage_module in `ls /etc/portage/bashrc.d/`
do
#echo Loading ... $portage_module
pre_pkg_setup() { echo -n .; }
source /etc/portage/bashrc.d/$portage_module
pre_pkg_setup
#echo Finished ... $portage_module
done
#echo Finished hook pre_pkg_setup
}
post_pkg_setup() {
#echo In hook post_pkg_setup
for portage_module in `ls /etc/portage/bashrc.d/`
do
#echo Loading ... $portage_module
post_pkg_setup() { echo -n .; }
source /etc/portage/bashrc.d/$portage_module

#echo Finished ... $portage_module

#echo Finished hook post_pkg_setup
}
pre_pkg_nofetch() {
#echo In hook pre_pkg_nofetch

And here's the hook handler script. You'll need to save it to a file and make it executable with "chmod u+x hook_handler".
| Code: | #!/bin/sh
scripts_dir="/etc/portage/bashrc.scripts"
links_dir="/etc/portage/bashrc.d"
available_handlers=
installed_handlers=
install_handler=
install_handler_value=50
uninstall_handler=
while getopts aiI:U name
do
case $name in
a) available_handlers=1;;
i) installed_handlers=1;;
I) install_handler=1
install_handler_value="$OPTARG";;
U) uninstall_handler=1;;
?) printf "Usage: %s: [-aiIU]\n" $0
printf " -a : List all available hook handlers\n" $0
printf " -i : List all installed hook handlers\n"
printf " -I[level] <handler> : Install <handler> at level [level]. Level defaults to 50\n"
printf " -U <handler> : Uninstall the specified handler\n"
exit 2;;
esac
done
if [ ! -z "$available_handlers" ]; then
ls /etc/portage/bashrc.scripts/ | grep -v '^.*~$'
fi
if [ ! -z "$installed_handlers" ]; then
ls /etc/portage/bashrc.d/ | grep -v '^.*~$'
fi
if [ ! -z "$install_handler" ]; then
shift $(($OPTIND - 1))
module=${1}
if [[ -z "${module}" && ! -z "${install_handler_value}" ]]; then
module="${install_handler_value}"
install_handler_value=50
fi
if [[ -f ${scripts_dir}/${module} ]]; then
echo Installing handler ${module} at level ${install_handler_value}
ln -s ${scripts_dir}/${module} ${links_dir}/${install_handler_value}-${module}
else
echo $module does not exist
fi
fi
if [ ! -z "$uninstall_handler" ]; then
shift $(($OPTIND - 1))
module=${1}
if [[ -f ${links_dir}/${module} ]]; then
echo Uninstalling handler ${module}
rm ${links_dir}/${module}
else
echo $module is not installed
