# Tests of array options in the options engine (options_array_* in options.c
|
|
# and the array handling in cmd-set-option.c / cmd-show-options.c).
|
|
#
|
|
# Array options are keyed by string, with numeric-looking keys kept compatible
|
|
# with the old numeric forms. This exercises: setting a whole array from a
|
|
# separator-delimited string; per-key set with option[key]; -a append (which
|
|
# lands at the next free numeric key); show ordering by numeric keys first in
|
|
# ascending order followed by string keys in strcmp order; preservation of gaps;
|
|
# per-key unset with -u; show -v of a single key and of a missing key; and
|
|
# per-option separators (user-keys splits only on comma, update-environment on
|
|
# space or comma).
|
|
#
|
|
# update-environment (session), status-format (session), user-keys (server)
|
|
# and command-alias (server) are used as representative array options.
|
|
#
|
|
# options-scope.sh covers scoping/inheritance and options-values.sh covers
|
|
# value validation.
