TBCEditor Syntax-Highlighting Editor
A new syntax-highlighting editor has been unleashed upon the Delphi world by Lasse Rautiainen, it’s named TBCEditor, and it is quite full-featured, clean, stable and fast.
The main source code is TBCEditor on github and supports Delphi XE4-XE8, I have made a fork TBCEditorXE on bitbucket which supports XE.
