Since yoshi does a good job of ignoring lines that do not have yoshi commands, one can use the same file for a bash scrip. copy the foollowing and save the file as "viewtext" then set the executable bits. This will display the Yoshi command file in a text display, then chose to run yoshi Default or not depending on the cancel button.

DIR="$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )"
cd "$DIR"
yoshi viewtext > /tmp/yoshout

while IFS='' read -r line || [[ -n "$line" ]]; do
    var1=$(echo $line | cut -f1 -d=)
    var2=$(echo $line | cut -f2 -d=)
    eval $var1='$var2'
done < "/tmp/yoshout"

if [ "$test" == "yes" ]; then
# skip over yoshi commands

*.title = Welcome to Yoshi
#*.look = no-border
#*.look = Bordered
#*.look = Floating
#*.look = Modal
#*.x = 50

Interesting. You're relying on the fact that bash is a fairly primitive interpreter that works strictly line-by-line, unlike, say, the yab interpreter, which checks the entire program for errors before it is run. This opens up a lot of possibilities. I must think about this.
