Examples

Welcome to the ngs wiki!

In this wiki we will assemble simple examples and Q&A, about some of the most valuable NGS features. They are not in any particular order, or logic, but rather some useful things as we develop the language and the feature set.

List all top level functions in NGS

ngs -pi 'globals().filterv(Fun)'

Match all occurrences of regular expression

Get all certificates from a certificate chain

certs = read(fileName) ~~ /-----BEGIN CERTIFICATE-----.*?-----END CERTIFICATE-----/ms

Parse openssl output (subject), convert to a Hash

subject = (`echo ${cert} | openssl x509 -subject -noout` - Sfx("\n") - Pfx("subject= /")).split("/").map(split(X, "=")).Hash()

• - Sfx("\n") removes newline at the end
• - Pfx("subject= /") removes undesired prefix of the string
• .split("/") splits the line by /, resulting an array of strings
• .map(split(X, "=")) splits each string in the array, resulting an array of the form [["k1", "v1"], ["k2, "v2"]]
• .Hash() converts array of the form [["k1", "v1"], ["k2, "v2"]] to a Hash
