NAME

Yash - A script to load YAML file inside shell scripts

VERSION

Version 0.2

yash [-f file] [--scalar|--array|--hash|--count] [path]

Print the content of a node (in YAML):

yash [path]

Check if the reached item is a scalar/array/hash:

yash [--scalar|--array|--hash] [path]

Count the size of a list, the number of keys of a hash (returns 1 for a scalar):

yash --count [path]

Print the values of a list or a hash (at least one line for each element, but some elements can take several lines as they are dumped in YAML)

yash --values [path]

Print the keys of a hash (one line per key, in plain text):

yash --keys [path]

Path is the sequence of array indexes or hash keys needed to reach the wanted node. It can be omitted in order to select the root node.

YAML data can come from the standard input or from the file given by the -f option.

See the tests for more examples.

Note: for --keys you should use a while loop instead of a for loop to avoid problems with spaces in values.

yash -f $CONFIG | while read line; do
  print $line
done
