New in Version 15.7
New Regular Expression Engine
You can now selectOnigmo as the regular expression engine in addition toBoost.Regex. IfOnigmo is selected as the regular expression engine, you can use character types such asp{Han},p{Hangul},p{Hebrew}, etc. To find more details about theOnigmo regular expression syntax, please viewhttps://github.com/k-takata/Onigmo/blob/master/doc/RE and Unicode Propertieshttps://github.com/k-takata/Onigmo/blob/master/doc/UnicodeProps.txt.
Test results
WhileFind,Replace, andFilter tasks using some regular expressions are much faster usingOnigmo compared toBoost.Regex,Boost.Regex becomes faster with some other regular expressions. Since the development is still in progress, the test results might be changed in the future.
