Re: [titan-dev] Regular expression escaping in configuration file

[Elemér Lelik <elemer.lelik@xxxxxxxxxxxx>]

Hi Harald,

Please try to double-escape (e.g. as in '\\$') the symbols in question; the config file is parsed in several layers.
Please let me know if it works(or does not) .

Best regards
Elemer

Subject: [titan-dev] Regular expression escaping in configuration file

Hi!

I'm using Eclipse Titan 6.2.0 and am currently playing with the TELNETasp TestPort.  This port requires the user to specify the prompt on the telnet server for use with "buffered" mode.  This works fine for a fixed prompt situation.  For variable prompts (such as those that change with context of where you are in the navigation of a MIB), one can specify regular expressions, e.g. using "REGEX_PROMPTn" variables.

However, as soon as want to use the '\' escaping character to include symbols like () or # in the prompt, the Titan test executor complains:

Parse error in configuration file `sysinfo/Test.cfg': in line 15, at or before token `\$': Invalid escape sequence in string literal.

Can somebody explain to me what is the correct method to escape in regex's spcified in the config file?
