This will allow people using spacemacs-base to have finer control over what additional packages they install on top of base. The proposed split is as follows spacemacs-editing: - aggressive-indent - avy - bracketed-paste - clean-aindent-mode - eval-sexp-fu - expand-region - hexl - hungry-delete - iedit - lorem-ipsum - move-text - neotree - pcre2el - smartparens spacemacs-editing-visual-packages: - adaptive-wrap - auto-highlight-symbol - highlight-indentation - highlight-numbers - highlight-parentheses - hl-anything - indent-guide - linum-relative - rainbow-delimiters - volatile-highlights spacemacs-evil-packages: - evil-anzu - evil-args - evil-exchange - evil-iedit-state - evil-indent-plus - evil-jumper - evil-lisp-state - evil-mc - evil-nerd-commenter - evil-matchit - evil-numbers - evil-search-highlight-persist - evil-terminal-cursor-changer - evil-tutor - evil-unimpaired spacemacs-language-packages: - define-word - google-translate spacemacs-ui-packages: - ace-link - ace-window - buffer-move - centered-cursor - desktop - doc-view - flx-ido - info+ - open-junk-file - window-numbering spacemacs-ui-visual-packages: - fancy-battery - golden-ratio - leuven-theme - neotree - smooth-scrolling - spaceline - vi-tilde-fringe - zoom-frm

;;; Change Log:
|
|
;;
|
|
;; 2011/01/04 dadams
|
|
;; Removed autoload cookies from non-interactive functions.
|
|
;; 2010/01/12 dadams
|
|
;; 1-window-frames-on, multi-window-frames-on:
|
|
;; save-excursion + set-buffer -> with-current-buffer.
|
|
;; 2008/04/05 dadams
|
|
;; get-a-frame: Define without using member-if.
|
|
;; 2005/10/31 dadams
|
|
;; read-frame: Swapped default and init values in call to completing-read.
|
|
;; 2004/11/26 dadams
|
|
;; Added frame-geom-spec-numeric and frame-geom-value-numeric.
|
|
;; 2004/03/19 dadams
|
|
;; read-frame: 1) if default is a frame, use its name,
|
|
;; 2) use frame-name-history, not minibuffer-history,
|
|
;; and use make-frame-names-alist, not frame-alist,
|
|
;; in completing-read
|
|
;; 1996/02/14 dadams
|
|
;; Added: window-coords, distance.
