Description: |
It might be expensive to build a log message: log::log debug "XML of node $Node is '[$node asXml]'" An extensive xml representation is build for log purposes and thrown away if not logged. It is proposed to add a command logsubst, to do variable and command expansion only in the log case: log::logsubst debug {XML of node $Node is '[$node asXml]'} The substitution is done within the log command only if debug log level is set. Implementation starting with commit [ec9cf4bb6f] in branch [rfe-19607f927b-logeval]. A practical usage is tclws (where the upper examples come from). The following commit introduces this optimisation and includes an emulator for older tcllib log packages: | |||
