Semikolon verdoppeln

[dero]

Hey,

bin jahrelanger FHEM-Nutzer, aber eins habe ich immernoch nicht kapiert: Was ist der genaue Grund, warum man Semikolons verdoppeln muss?

Danke!

Multiple FHEM commands are separated by semicolon (. In order to use semicolon in perl code or shell programs, they have to be escaped by the double semicolon (;. See the Notes section of the notify chapter on command parameters and escape rules.
E.g. the following first command switches Lamp1 off at 07:00 and Lamp2 immediately (at the point of definition), the second one switches both lamps off at 07:00.
define lampoff at 07:00 set Lamp1 off; set Lamp2 off
define lampoff at 07:00 set Lamp1 off;; set Lamp2 off
For every further indirection you need to double the semicolons:, e.g. to switch on every day 2 devices at 7:00 for 10 minutes you have to write:
define onAt at 07:00 set Lamp1 on;;set Lamp2 on;; define offAt at +00:10 set Lamp1 off;;;;set Lamp2 off
Don't dispair, the previous example can also be written as
define onAt at 07:00 set Lamp1,Lamp2 on-for-timer 600

Ja, aber ist das eine Perl-Spezialität oder liegt es an FHEM?

Also ist FHEM wohl die Antwort auf Deine Frage. FHEM ist in Perl geschrieben, also ein "level" höher.
