Re: [hylafax-users] * Hylafax 4.1.8 - Regular Expression Problems *



You're mis-understanding regular expressions.

If we have:
ModemGroup:             "outnow:ttyUSB[0,2-5]"
Works, but doesn't send out on ttyUSB1 which is expected.



This regex will match ttyUSB0000, ttyUSB20, and ttyUSB522343234.

If we have:
ModemGroup: "outnow:ttyUSB[0,1,2-5]"
It sends out on ALL lines...it seems like it is matching both the first and
the second number.


Which is why when you include the "1" you match ttyUSB10, ttyUSB10, ttyUSB11, and ttyUSB12. If this is matching ttyUSB9 then I would guess there is a bug in hylafax. To match ttyUSB1 and not ttyUSB10 you need to put "outnow:ttyUSB[0-5]$". The dollar sign means thats the end of the string.

I have checked to see if regex is the problem by doing the following:
[root@roadrunner etc]# ls config.ttyUSB[0-8] config.ttyUSB0  config.ttyUSB2
config.ttyUSB4  config.ttyUSB6  config.ttyUSB8
config.ttyUSB1  config.ttyUSB3  config.ttyUSB5  config.ttyUSB7

And this gives me the result I need...


And thats not a regex. Thats file globbing in you sheel. Regex will match substrings, while file globbing only matches complete strings. If it was a regex you'd also match config.ttyUSB02342, config.ttyUSB12, config.ttyUSB8232423, etc.

HylaFAX scheduler on roadrunner.ext.maynegroup.com: Running Modem ttyUSB1 (Outgoing1): Running and idle Modem ttyUSB2 (Outgoing2): Running and idle Modem ttyUSB3 (Outgoing3): Running and idle Modem ttyUSB4 (Outgoing4): Running and idle Modem ttyUSB5 (Outgoing5): Waiting for modem to come ready Modem ttyUSB0 (Outgoing0): Running and idle Modem ttyUSB6 (Incoming0): Running and idle Modem ttyUSB7 (Incoming1): Running and idle Modem ttyUSB8 (Incoming2): Running and idle Modem ttyUSB9 (Incoming3): Running and idle Modem ttyUSB10 (Incoming4): Running and idle Modem ttyUSB11 (Incoming5): Running and idle Modem ttyUSB12 (Incoming6): Running and idle

Any ideas?

I can't test modemgroup regex's here so I can't add more than that explaination.
