# URL-encode a string

|

# Encodes a string using RFC 2396 URL-encoding (%-escaped).
|
|
# See: https://www.ietf.org/rfc/rfc2396.txt
|
|
#
|
|
# By default, reserved characters and unreserved "mark" characters are
|
|
# not escaped by this function. This allows the common usage of passing
|
|
# an entire URL in, and encoding just special characters in it, with
|
|
# the expectation that reserved and mark characters are used appropriately.
|
|
# The -r and -m options turn on escaping of the reserved and mark characters,
|
|
# respectively, which allows arbitrary strings to be fully escaped for
|
|
# embedding inside URLs, where reserved characters might be misinterpreted.
|
|
#
|
|
# Prints the encoded string on stdout.
|
|
# Returns nonzero if encoding failed.
|
|
#
|
|
# Usage:
|
|
# omz_urlencode [-r] [-m] [-P] <string>
|
|
#
|
|
# -r causes reserved characters (;/?:@&=+$,) to be escaped
|
|
#
|
|
# -m causes "mark" characters (_.!~*''()-) to be escaped
|
|
#
|
|
# -P causes spaces to be encoded as '%20' instead of '+'
