Text Editors
EmEditor
EmEditor remains my favorite text editor, not just one of, but the no. 1 for me. Unfortunately it lives only on Windows.
CotEditor
Two days ago (2/23/23) I found CotEditor. I had briefly tried it and uninstalled it because I didn't look hard enough to find out it has much better Regex 正規表式 support than Sublime Text. It recognizes, drum rolls please, \p{Han}
for Chinese characters!
Sublime Text
I make do with Sublime Text on MacOS but its interface seems lame especially for Regex 正規表式 search and replace. CotEditor has made this obsolete.
UltraEdit for Mac
I am coveting this famous Windows editor for its functionality of find & replace in multiple files in a directory recursively, lamentably missing in CotEditor. It is unfortunately expensive at $150 for a perpetual license.
