dwcB

Emacs minor mode for a (sort of) radical keybinding scheme. Currently has default support for Lisp, Python, Org and Helm.

Usage (define dwcB maps with dwcB-configure)

dwcB-configure

• :key
  • A minor mode or major mode name to which the produced dwcB map will associate. Alternatively, a name for a new dwcB map (useful if you want to build map hierarchies using :parent). Omit :key to configure dwcB’s global map.
• :base
  • A base map on which to build the produced dwcB map.
• :parent
  • A parent map from which the produced dwcB map should inherit.
• :gen-binds
  • Bindings in the general namespace (i.e., not necessarily under a prefix key).
• :env-binds
  • Bindings under the major prefix.
• :wnd-binds
  • Bindings under the window prefix.

Describing dwcB maps with :key

Declare a dwcB map with :key. Build this map from prog-mode-map. Using :key this way allows the creation of base maps to be used by more specific dwcB binding configurations.

(dwcB-configure
 :key 'prog-map
 :base prog-mode-map
 :env-binds: `(
               (,dwcB-note-key . comment-dwim)
               )
 )

Declare a dwcB map with :key. Set it to derive from `prog-map’ with :parent. :env-binds prefixes corresponding bindings with the major prefix key (“C-e” by default).

(dwcB-configure
 :key 'lisp-map
 :parent 'prog-map
 :env-binds`(;; Beg/End

Associating modes and maps with :key

Associate the (minor) mode specified by :key with a binding. Use :parent to inherit from newly created `lisp-map’. The following setting will be configured to run when `emacs-lisp-mode’ is turned on.

(dwcB-configure
 :key 'emacs-lisp-mode
 :parent 'lisp-map
 :env-binds `(
              (,dwcB-interpret-key . ielm)
              )
 )
