Since FF library is for US. How can I get the SMB and HML fators for European markets (UK, France, Germany, etc)?
You can get a pooled European market at Kenneth French's website, you just have to scroll down. These are current.
German factors are here, but I think they might have stopped updating them in 2016: https://www.wiwi.hu-berlin.de/de/professuren/bwl/bb/data/fama-french-factors-germany/fama-french-factors-for-germany
Stefano Marni has a large set of monthly factors, including France, however, they stop in 2013.
Similarly, Tharayan and Christidis offer daily UK factors, they stop in June 2015.
