EmacsとかLispとか可視化とか

Emacsのフラットデザインっぽくする(FlatUI)

Emacsのテーマは今までsolarizedを使ってきましたが、

定番すぎたのでもうちょい自分らしく変えようと思い、

フラットデザインをとりいててみました。

テーマ

john2x/flatui-theme.el · GitHub

M-x list-packegesでは入ります。

以下をinit.elに記述(自分はファイル分割してます)

;;;カラースキーム
(color-theme-initialize)
(load-theme 'flatui t)

モードライン

気分屋なのでたまにテーマを変更します。

その際いちいち設定しなおすのが面倒なので

face-attributeを使ってテーマと連動する形で変わるようになってます。

↓をベースに、なるべく編集状況によってずれが生じないようにしてます。

Amit's Thoughts: Emacs: custom mode line

その他マイナーモードで表示しないものを簡単に指定できるようにしてます。

タブ

自分はタブが欲しい派なのでtabbar.elを使っています。

こちらはモードラインの色(つまりさらにたどってテーマの色)と連動します。

ポイントはinitの際、モードラインより後に読み込みするようにすることです。

(同様にモードラインはテーマより後に読み込みます)

(require 'tabbar)

;; タブ上でマウスホイール操作無効
(tabbar-mwheel-mode -1)
;; グループ化しない
(setq tabbar-buffer-groups-function nil)

(setq tabbar-use-images nil)
;; 左に表示されるボタンを無効化
(dolist (btn '(tabbar-buffer-home-button
               tabbar-scroll-left-button
               tabbar-scroll-right-button))

                 (cons "" nil))))

                                   buf)))
                             (buffer-list)))))
    ;; Always include the current buffer.

うん、結構気に入ってます。

しかしやっぱり暗い背景がすきなので現在のテーマをベースに自作テーマ作成中です←
