bash script to set value inside gopass using vim as editor (this is a little hack, some special chars can break it)

gset.sh

#!/bin/bash

# usage: gset.sh <GOPASS_KEY_PATH> <IDENTIFIER> <VALUE>  
#    set a unique value on an item
#    for password use '-o' as key

GOPASS_KEY=$1
IDENT=$(echo "$2" | sed 's_/_\\\\/_g')
VALUE=$(echo "$3" | sed 's_/_\\\\/_g')

if [[ "$IDENT" = "-o" ]] ;then
    export EDITOR="vim '+:1,1 s/.*/$VALUE/' +:wq"
else
    # if identifier is found, edit it, else add it at the end 
    export EDITOR='vim "+if search('\'$2': .*'\'') | s/.*/'$IDENT': '$VALUE'/ | else | \$s/\$/\\r'$IDENT':\ '$VALUE'/ | endif" +:wq'
fi
gopass edit $GOPASS_KEY
