+ enable lexical-scope everywhere (lexical-binding = t): ~5-10% faster
startup; ~5-20% general boost
+ reduce consing, function calls & garbage collection by preferring
cl-loop & dolist over lambda closures (for mapc[ar], add-hook, and
various cl-lib filter/map/reduce functions) -- where possible
+ prefer functions with dedicated opcodes, like assq (see byte-defop's
in bytecomp.el for more)
+ prefer pcase & cond (faster) over cl-case
+ general refactor for code readability
+ ensure naming & style conventions are adhered to
+ appease byte-compiler by marking unused variables with underscore
+ defer minor mode activation to after-init, emacs-startup or
window-setup hooks; a customization opportunity for users + ensures
custom functionality won't interfere with startup.
linum-mode *really* slows down buffers when they're displayed in more
than one window. This lag isn't present in nlinum. nlinum isn't perfect
either but... lesser of two evils.
This includes advisors and an ESC hook to mitigate the issue of
disappearing nlinum line numbers.
If Emacs wasn't built with X, Cocoa or NS display support (as is the
case for evm emacs-25.1-travis build), the fringe library is missing and
throws errors.
Uniquify's effect is invisible except in places where buffer-name is
used (like in switch-buffer), where it can be very helpful to
distinguish between clashing buffers.
