#
|
|
# This function is the common guts of the gen-applied-string /
|
|
# gen-unapplied-string / set-patch-format dance of several backends.
|
|
#
|
|
# Parameters:
|
|
# $1 - name of an array parameter to be the argument to gen-applied-string
|
|
# (patches in reverse order)
|
|
# $2 - name of a parameter to store the applied-string in
|
|
# $3 - name of an array parameter to be the argument to gen-unapplied-string
|
|
# (patches in order)
|
|
# $4 - name of a parameter to store the unapplied-string in
|
|
# $5 - context argument for use in zstyle getters
|
|
# $6 - name of a parameter to store a patch-format format string in
|
|
# $7 - name of an assoc parameter with extra $hook_com key-value pairs for the
|
|
# set-patch-format hook invocation, or '' for none
|
|
# $8 - name of a function that sets $reply to extra arguments for the patch-format zformat call, or '' for none
|
|
#
|
|
# The expanded patch-format string is returned in $REPLY.
|
|
#
|
|
# Output:
|
|
# - $hook_com is overwritten and the keys 'applied', 'applied-n',
|
|
# 'unapplied', 'unapplied-n', 'all-n' are set.
