ElectricCommander includes a general-purpose postprocessor named "postp" that uses regular expression patterns to detect interesting lines in a step log. Postp is already configured with patterns to handle many common cases such as error messages and warnings from gcc, gmake, cl, junit, and cppunit, or any error message containing the string "error." Postp is easy to use by simply setting the postprocessor for a step to "postp." Postp also supports several useful command-line options.
For a full description of the postprocessor with detailed instructions and examples, see ElectricCommander online help, the "Postprocessors" help topic.
