Again Üstün Özgür. He is your peace of mind this time “Emacs-friends: an Emacs package to open the current file with other applications” presentation entitled. This presentation, published in the February 1, 2016. Üstün Özgür, continues to tell Emacs. As you know, GNU Emacs; content-aware editing modes, including syntax coloring, for many file types. Complete built-in documentation, including a tutorial for new users. Full Unicode support for nearly all human scripts. Highly customizable, using Emacs Lisp code or a graphical interface. An entire ecosystem of functionality beyond text editing, including a project planner, mail and news reader, debugger interface, calendar, and more. A packaging system for downloading and installing extensions. In 1976, Stallman wrote the first Emacs (“Editor MACroS”), and in 1984, began work on GNU Emacs, to produce a free software alternative to the proprietary Gosling Emacs. GNU Emacs was initially based on Gosling Emacs, but Stallman’s replacement of its Mocklisp interpreter with a true Lisp interpreter required that nearly all of its code be rewritten. This became the first program released by the nascent GNU Project. GNU Emacs is written in C and provides Emacs Lisp, also implemented in C, as an extension language.
