History

Stefan Kangas afde53cd81 Improve substitute-command-keys performance The previous conversion of describe_vector from C to Lisp for the keymap and char table case lead to an unacceptable performance hit. Moving back to the C version, as we do here, makes this function around 50 times faster. The Lisp version of `substitute-command-keys' was benchmarked using the form `(documentation 'dired-mode)', which now takes less than 8 ms on my machine. This is around 16 times slower than the previous C version. Thanks to Stefan Monnier for helpful pointers on benchmarking. * src/keymap.c (Fhelp__describe_vector): New defun to expose describe_vector to Lisp for keymaps and char tables. (syms_of_keymap): New defsubr for Fhelp__describe_vector. * lisp/help.el (describe-map): Use above defun instead of Lisp version. (help--describe-vector): Remove defun; keep it commented out for now.		2020-10-18 17:25:23 +02:00

README

This directory contains source code for the parts of Emacs that are
written in Emacs Lisp.  *.el files are Emacs Lisp source, and the
corresponding *.elc files are byte-compiled versions.  Byte-compiled
files are architecture-independent.

The term subdirectory contains Lisp files that customize Emacs for
certain terminal types.  When Emacs starts, it checks the TERM
environment variable to get the terminal type and loads
'term/${TERM}.el' if it exists.

The other subdirectories hold Lisp packages grouped by their general
purpose.
