;; Ivy integration with the excellent program, clipmenu.
|
|
||||||
;;
|
|
||||||
;; clipmenu is a simple clipboard manager xsel. Usually clipmenu integrates with
|
|
||||||
;; dmenu. This Emacs module integrates with ivy. Launch this when you want to
|
|
||||||
;; select a clip.
|
|
||||||
;;
|
|
||||||
;; The following environment variables allow you to customize clipmenu's
|
|
||||||
;; behavior:
|
|
||||||
;;
|
|
||||||
;; - CM_DIR: specify the base directory to store the cache dir in
|
|
||||||
;; (default: $XDG_RUNTIME_DIR, $TMPDIR, or /tmp)
|
|
||||||
;; - CM_HISTLENGTH: specify the number of lines to show in ivy. (default: 8)
|
|
||||||
;;
|
|
||||||
;; Other variables for customizing clipmenu are defined herein.
|
|
||||||
;;
|
|
||||||
;; For more information, see `clipmenu --help`.

;; Ivy integration with the clipboard manager, clipmenu. Essentially, clipmenu
|
||||||
|
;; turns your system clipboard into a list.
|
||||||
|
;;
|
||||||
|
;; To use this module, you must first install clipmenu and ensure that the
|
||||||
|
;; clipmenud daemon is running. Refer to the installation instructions at
|
||||||
|
;; github.com/cdown/clipmenu for those details.
|
||||||
|
;;
|
||||||
|
;; This module intentionally does not define any keybindings since I'd prefer
|
||||||
|
;; not to presume my users' preferences. Personally, I use EXWM as my window
|
||||||
|
;; manager, so I call `exwm-input-set-key' and map it to `ivy-clipmenu/copy'.
|
||||||
|
;;
|
||||||
|
;; Usually clipmenu integrates with rofi or dmenu. This Emacs module integrates
|
||||||
|
;; with ivy. Launch this when you want to select a clip.
|
||||||
|
;;
|
||||||
|
;; Clipmenu itself supports a variety of environment variables that allow you to
|
||||||
|
;; customize its behavior. These variables are respected herein. If you'd
|
||||||
|
;; prefer to customize clipmenu's behavior from within Emacs, refer to the
|
||||||
|
;; variables defined in this module.
|
||||||
|
;;
|
||||||
|
;; For more information:
|
||||||
|
;; - See `clipmenu --help`.
