Examples

basic

echo '{{flowers}} are {{color}}' | coin -a 'flowers:roses' -a 'color:red'

# roses are red

The same result can be produced by using multiple coin calls:

echo '{{flowers}} are {{color}}' | coin -a 'flowers:roses' | coin -a 'color:red'

In some contextes curly brackets might might be reserved or not available for other reasons. This can be mitigated by using different placeholder indicators:

echo '<<flowers>> are <<color>>' | coin -o '<<' -c '>>' -a 'flowers:roses' -a 'color:red'

file arguments

echo -n "cornflowers" > /tmp/flowers.txt
echo -n "blue" > /tmp/color.txt
echo '{{flowers}} are {{color}}' | coin -a 'flowers:@/tmp/flowers.txt' -a 'color:@/tmp/color.txt'

# cornflowers are blue

data file

echo -e "flowers: daffodills\ncolor: yellow" > /tmp/data.yaml
echo '{{flowers}} are {{color}}' | coin -d /tmp/data.yaml

# daffodills are yellow
