Want to copy log without escape


The following fragment is a example of test case log emitted by Katalon Studio 5.10.0 on Windows 7. I copy&pasted the lines out of the Log Viewer.

In there you can find a lot of escape sequences, for example e[34m, e[0;39m, e[39m2. These escape sequences are annoying. They make the pasted text hard to read.

In the Katalon Studio GUI, in the log view pane, I found a button titled “Copy text with escape”:

I would rather like to have a button “Copy text without escape

Unable to verify element property value
Reducing log level for the LogViewer

This issue annoys me a lot when I make a post into this Forum with log information attached.

Please fix this A.S.A.P.


A temporary workaround in the meantime is to delete all text matching the regex \u001b\[[\d;]*[A-HJKSTfimnsu].


In the version 5.10.1, I do not see the escape sequences such as e[34m , e[0;39m , e[39m2 any longer.

@Katalon team

Have you changed the code already?


Yes if you are on macOS. There is another issue and we have to temporarily disable colored logs.
