Is this something you will add because this new logging api also messes up using lou_allround. It already has a way to know the input and output buffers but now has extra spam.

However in the meantime you can redirect the logging output to a file with a command like: lou_translate -b en-us-g2.ctb 2>./output.log Or if you do not want any storing of the logging output you could write it to /dev/null lou_translate -b en-us-g2.ctb 2>/dev/null Michael Whapples On 24/06/2014 11:33, Ken Perry wrote: I was trying to do some testing and the lou_translate command spams with output and it did not use to do this. It shows the in buff, out buff, and it shows a message saying translating. You used to be able to turn these messages on in lou_allround but not in lou_translate. This makes it hard to test on large files if it spams you with all kinds of output. It used to translate a file silently and quickly. Is there a reason this has been changed? ken
