This package shortens major mode names by using a set of user-defined rules.

The package is available via MELPA, so you can just type M-x package-install RET cyphejor RET.

If you would like to install the package manually, download or clone it and put on Emacs' load-path. Then you can require it in your init file like this:

(require 'cyphejor)

First, you need to set the value of the variable cyphejor-rules. This variable contains rules that are used to generate new names for major modes from their symbol names, that is, values of the major-mode variable.

cyphejor-rules should be a list. Every element of the list should have the following form:

(string replacement &rest parameters)

where string is a word in the major mode's symbol name, replacement is a string to be used instead of that word, parameters is a list that may contain the following keywords:

• :prefix—put the component at the beginning of the resulting string
• :postfix—put the component at the end of resulting string

The following keywords influence the algorithm in general:

• :downcase—replace words that are not matched explicitly with their first letter downcased

• :upcase—replace words that are not matched explicitly with their first letter upcased

If nothing is specified, a word will be used unchanged, separated from other words with spaces if necessary.

Example of a setup:

(setq
 cyphejor-rules
 '(:upcase
   ("bookmark"    "→")
   ("buffer"      "β")
   ("diff"        "Δ")
   ("dired"       "δ")
   ("emacs"       "ε")
   ("inferior"    "i" :prefix)
   ("interaction" "i" :prefix)
   ("interactive" "i" :prefix)
   ("lisp"        "λ" :postfix)
   ("menu"        "▤" :postfix)
   ("mode"        "")
   ("package"     "↓")
   ("python"      "π")
   ("shell"       "sh" :postfix)
   ("text"        "ξ")
   ("wdired"      "↯δ")))

cyphejor-mode can be enabled like this:

(cyphejor-mode 1)

You can access the customization interface via M-x customize-group cyphejor RET.
