# General rules: all replacing is in-line. Respect unsupported values, comments
|
|
# and as many spacing as possible.
|
|
|
|
# The concept of keyword (kw) here is a key, normaly in its own line, whose
|
|
# boolean representation is its own existence.
|
|
|
|
# A $re is a regular expression. In most functions here, regular expressions
|
|
# are converted to simple separators, by using gst_replace_regexp_to_separator.
|
|
# This makes it easier to convert a parse table into a replace table.
|
|
|
|
# Every final replacing function to be used by a table must handle one key
|
|
# at a time, but may replace several values from there.
|
|
#
|
|
# Return 0 for success, and -1 for failure.
|
|
#
|
|
# Most of these functions have a parsing counterpart. The convention is
|
|
# that parse becomes replace and split becomes join:
|
|
# gst_parse_split_first_str -> gst_replace_join_first_str
|
|
|
|
# Additional abstraction: replace table entries can have
|
|
# arrays inside. The replace proc will be ran with every
|
|
# combination that the arrays provide. Ex:
|
|
# ["user", \&gst_replace_foo, [0, 1], [2, 3] ] will replace
|
|
# using all possibilities in the combinatory of [0, 1]x[2, 3].
|
|
# Check RedHat 7.2's network replace table for further
|
|
# enlightenment.
