User defined extensions

This section needs code review. I'm not sure if the functionality described here makes sense anymore. In particular, the ability to run code before and after we pick a certain environment is already available as part of Python virtual environments and so, chances are that we remove the entire functionality.

You may find useful to run something before and/or something after you load [these] scripts [provided by this package] into your terminal session.

This way, you can define defaults for environment variables before scripts run. You can also adjust keyboard configurations and other preferences after all scripts run.

Actions before loading scripts

Simply create a file named $HOME/.bashrc-scripts/head and it will be executed before [these] scripts [provided by this package] run.

This is an example which may be useful if you visit several customers:

#!/bin/bash

function nmcli_connected_wifi {
  nmcli -t -f active,ssid dev wifi | grep -F yes: | cut -d: -f2
}

#--
# Define environment variable WORKSPACE
# In case I'm connected to "my customer" access point, I'd rather defined it as
# a folder which contains "my customer's" stuff. Otherwise, I simply left undefined.
#--
case "$(nmcli_connected_wifi)" in
  "CUSTOMER_A") export WORKSPACE=$HOME/Documents/customers/CustomerA/
                ;;
  "CUSTOMER_B") export WORKSPACE=$HOME/Documents/customers/CustomerB/
                ;;
  *)            export WORKSPACE=$HOME/workspace
                ;;
esac

Actions after loading scripts

Simply create a file named $HOME/.bashrc-scripts/tail, as the example below shows:

#!/bin/bash

#--
# Select preferences in case a VPN connection is active.
#--
if [[ $( nmcli -t -f device,type,state,connection dev | grep -F tun:connected:tun0 ) ]] ;then
  echo "VPN is active"
fi

#--
# Configure keyboard, depending on which one is connected.

if [[ $( lsusb | grep -F 17f6:0905 | grep -F Unicomp ) ]] ;then
  carpalx_hyena_us
elif [[ $( lsusb | grep -F feed:6060 ) ]] ;then
  carpalx_hyena_us
else
  carpalx_hyena_gb
fi
