EmEditor v15.7.0 released!

Today, we are releasing EmEditor v15.7.0.

Updates from v15.6.1 include:

New General Features

  • You can now select Onigmo as the regular expression engine in addition to Boost.Regex. If Onigmo is selected as the regular expression engine, you can use character types such as \p{Han}, \p{Hangul}, \p{Hebrew}, etc. To find more details about the Onigmo regular expression syntax, please view https://github.com/k-takata/Onigmo/blob/master/doc/RE and Unicode Properties https://github.com/k-takata/Onigmo/blob/master/doc/UnicodeProps.txt.
  • This version allows you to search and replace CR and LF separately.
  • If you try to search for a string containing \r (CR) while the Treat CR and LF separately option is disabled, the prompt message “The search string contains CR. Do you want to enable the Treat CR and LF Separately option?” will appear now.
  • If the last line of the document is empty, regular expressions will not match the last line anymore.

New Options

  • The Default Regular Expression Engine drop-down list box was added to the Search tab of the Customize dialog box.
  • The Customize button was replaced with Advanced button in the Find/Replace dialog boxes. In the Advanced dialog box, more search options are included now.
  • The Advanced button was added to the Find toolbar.
  • The Show the Start window when the Down key is pressed on a new document check box was added to the Customize Start Window dialog box.
