What is difference between Emacs and XEmacs?
XEmacs was a branch version of Emacs that is no longer actively developed. XEmacs was first called Lucid Emacs, and was initially derived from a prerelease version of Emacs 19. Terms such as “Emacsen” and “(X)Emacs” are not wrong, but they are not very clear, so it is better to write “Emacs and XEmacs.”
What language is Emacs built over?
GNU Emacs is written in C and provides Emacs Lisp, also implemented in C, as an extension language. Version 13, the first public release, was made on March 20, 1985. The first widely distributed version of GNU Emacs was version 15.34, released later in 1985.
Who invented Emacs?
Richard Stallman
GNU Emacs is a free software text editor. It was created by GNU Project founder Richard Stallman.
What happened to XEmacs?
The domain still exists and according to whois was last updated in September 2015. The XEmacs Sourceforge page is still around, but appears to have received its last set of updates in 2009. Obviously a lot of links to the bug tracker, mailing list hosts etc are dead as they’re point to subdomains of xemacs.org.
What’s the difference between XEmacs and GNU Emacs?
Historically, XEmacs was for a long time (from the Lucid days in the late 1980s to GNU Emacs’s catch-up in the mid-200s) about one major version ahead of GNU Emacs in terms of features. XEmacs tended to be quicker at adopting new features and was more liberal in accepting outside code.
Why is XEmacs considered to be free software?
XEmacs is GNU software because it’s a modified version of a GNU program. And it is GNU software because the FSF is the copyright holder for most of it, and therefore the legal responsibility for protecting its free status falls on us whether we want it or not. This is why the term “GNU XEmacs” is legitimate.
Which is better Emacs or XEmacs for Lisp?
Both Emacsen support the Quail family of input methods (implemented in LISP) for many languages. As of XEmacs 21.4, although XEmacs supports preloaded Lisp using “unexec”, it is considered obsolete. XEmacs 21.4 uses a much more portable technique to “dump” and “preload” Lisp.
When was the last major revision of GNU Emacs?
The previous major revision occurred on January 1, 2001, by me. GNU Emacs has improved a fair amount, but the irreconcilable differences between the projects continue, with no resolution in sight.
