# frozen_string_literal: true
# Fetch a string from a URL (should only be used with 'small' remote files).
#
# This function should only be used with trusted/internal sources.
# This is especially important if using it in conjunction with `inline_template`
# or `inline_epp`.
# The current implementation is also very basic. No thought has gone into timeouts,
# support for redirects, CA paths etc.
Puppet::Functions.create_function(:'extlib::read_url') do
# @param url The URL to read from
# @return Returns the contents of the url as a string
# @example Calling the function
# extlib::read_url('https://example.com/sometemplate.epp')
