@dolist

From TinyMUX

Description

COMMAND: @dolist[/<switch>] [<delimiter>] <list>=<action>

list is a list of strings, which can be object numbers, attributes, or arbitrary words. action is a command to perform once for each item in list, replacing the special symbol ## with the corresponding item from list, and the symbol #@ with the position in the list, starting with one. By default, @dolist considers each item in list to be separated with spaces. If you specify the /delimit switch, then each item is considered to be separated by delimiter. delimiter must be a single character.

If present, switch can be any of:

/space - (Default) List elements are separated by spaces.

/delimit - List elements are separated by delimiter.

/notify - Queues a '@notify' after all commands in the list.

This command is particularly handy with lcon() and lexits().

Examples

@dolist [lcon(here)] = "[name(##)](##)

@dolist [lcon(here)] = @switch [get(##/last)]=*1990*,"[name(##)]

@va me = va vb vc

@do list [get(me/va)] = @emit [get(me/##)]

@dolist Frodo Bilbo Gandalf = page ## = HELP!!!! I've fallen into a pit.

@dolist/delimit , {Frodo, Bilbo Baggins, Gandalf} = page ## = HELP!!!!

@wait me="This is a semaphore.

@dolist/notify lnum(3)=say ##

> You say, "This is a semaphore."

> You say, "0"

> You say, "1"
