KDL is a small, document language with XML-like node semantics that looks like you’re invoking a bunch of CLI commands. It’s meant to be used both as a serialization format and a configuration language, much like JSON, YAML, or XML. It looks like this:
package {
name my-pkg
version "1.2.3"
dependencies {
// Nodes can have standalone values as well as
// key/value pairs.
lodash "^3.2.1" optional=#true alias=underscore
}
scripts {
// "Raw" and dedented multi-line strings are supported.
message """
hello
world
"""
build #"""
echo "foo"
node -c "console.log('hello, world!');"
echo "foo" > some-file.txt
"""#
}
// `\` breaks up a single node across multiple lines.
the-matrix 1 2 3 \
4 5 6 \
7 8 9
// "Slashdash" comments operate at the node level,
// with just `/-`.
/-this-is-commented {
this entire node {
is gone
}
}
}
