suppress_repeat_messages - Control how duplicate messages in output streams are handled
Synopsis
host% gridlabd -D suppress_repeat_messages=0|1|TRUE|FALSE host% gridlabd --define suppress_repeat_messages=0|1|TRUE|FALSE #set suppress_repeat_messages=0|1|TRUE|FALSE
Description
Some situations during simulations can result is some messages being repeated many times and clogging up output buffers. When suppress_repeat_messages is set, messages that are similar (not necessarily identical) are suppressed and only a single message is output followed by a message indicated how many time it was repeated.
By default suppress_repeat_messages is enabled.
