caws 0.2.0

configure AWS responsibly using profile names.

caws

configure AWS responsibly using profile names and environment vars.

rather than changing your AWS SDK credentials with aws configure, AWS suggests
setting the ENV var AWS_DEFAULT_PROFILE to a [profile] in your ~/.aws/credentials.
when set, this ENV var will over-ride the profile set with aws configure.

caws will write to an rc file setting AWS_DEFAULT_PROFILE to the given profile name.
if you do not have the rc file caws will create it for you.

you'll need to add . .cawsrc to your RC file (using bash: .bashrc or .bash_profile)

add new profiles using $ aws configure --profile newname

one benefit of using AWS_DEFAULT_PROFILE method instead of aws configure is the
ability to add which AWS profile you're currently using to your command prompt.

dependencies

python3
aws cli

usage

change AWS_DEFAULT_PROFILE to profilename
$ caws profilename

change AWS_DEFAULT_PROFILE to profilename and also update ~/.aws/credentials and ~/.aws/config
$ caws profilename --withcreds

show help and exit
$ caws -h

example bash usage

because python cannot source files on the parent process, caws has the unfortunate inability to update the ENV var it is updating.
therefore, a thin bash helper function can be used to run caws in the background:

kaws() {
 eval "caws $1 > /dev/null"
 . ~/.cawsrc  
}

example PS1 with colored path parts!

function color_path() {
    ROYGBIV=('\e[31m' '\e[38;5;208m' '\e[93m' '\e[92m' '\e[36m' '\e[94m' '\e[95m' '\e[97m' '\e[93m' '\e[38;5;208m' '\e[91m' '\e[95m' '\e[96m' '\e[34m' '\e[92m')
    explode_path=$(pwd)
    exploded=$(echo $explode_path | tr "/" "\n")
    final=""
    sep="/"
    x=0 
    for part in $exploded
    do  
        final+="${ROYGBIV[$x]}$sep$part\e[0m"
        x=$(expr $x + 1)
    done
    printf $final
}
parse_git_branch() {
    local b=$(git symbolic-ref HEAD 2> /dev/null)
    if [ "${b#refs/heads/}" != "" ]
    then
        printf " \e[38;5;208m(${b#refs/heads/})\e[0m"
    fi
