Regular Expressions modificators?

RouterOS Scripting

There is a text:

OK
^RSSI: 25
^HCSQ: "LTE",59,52,156,28

It is necessary here to catch the presence of a full line “OK”
The regular message does not work out as I need it:

{
:local str "OK\r\n^RSSI: 25\r\n^HCSQ: \"LTE\",59,52,156,28"
:if ($str~"^OK\$" = true) do={
  :put "YES"
} else={
  :put "NO"  
}
}

Is it possible to specify modifiers globally or locally in the ROS syntax? What would the search be line by line?

This is likely your only chance:

$str~"^OK(\r|\n|\r\n|\$)"

The ROS regex engine (whatever it is) doesn’t seem to support any the “(?m)” flag.

Since there are lots of or and it only match the \r\n
This could be used as well

$str~"^OK\r\n"

But it depends on your real input as well.

thanks, “OK” can be anywhere. It is also believed that the modems return the newline as “\r\n”
did this:

~"(^|\n)OK(\$|\r)"

.

But, the case-insensitive modifier is no longer missing(?i)
It’s a shame that things like this are not supported.
