Configuration Examples
Example 1
(require 'string-inflection)
;; C-q C-u is similar to the keybinding used by Vz Editor.
(global-unset-key (kbd "C-q"))
(global-set-key (kbd "C-q C-u") 'my-string-inflection-cycle-auto)
(defun my-string-inflection-cycle-auto ()
"switching by major-mode"
(interactive)
(cond
;; for emacs-lisp-mode
((eq major-mode 'emacs-lisp-mode)
(string-inflection-all-cycle))
;; for python
((eq major-mode 'python-mode)
(string-inflection-python-style-cycle))
;; for java
((eq major-mode 'java-mode)
(string-inflection-java-style-cycle))
;; for elixir
((eq major-mode 'elixir-mode)
(string-inflection-elixir-style-cycle))
(t
;; default
(string-inflection-ruby-style-cycle))))
Example 2
(require 'string-inflection)
;; default
(global-set-key (kbd "C-c C-u") 'string-inflection-all-cycle)
;; for ruby
(add-hook 'ruby-mode-hook
'(lambda ()
(local-set-key (kbd "C-c C-u") 'string-inflection-ruby-style-cycle)))
;; for elixir
(add-hook 'elixir-mode-hook
'(lambda ()
(local-set-key (kbd "C-c C-u") 'string-inflection-elixir-style-cycle)))
;; for java
(add-hook 'java-mode-hook
'(lambda ()
(local-set-key (kbd "C-c C-u") 'string-inflection-java-style-cycle)))
;; for python
(add-hook 'python-mode-hook
'(lambda ()
(local-set-key (kbd "C-c C-u") 'string-inflection-python-style-cycle)))
How to Use
For each of the following, place the cursor at emacs_lisp
and type C-q C-u
, the results will be as follows:
In the case of string-inflection-ruby-style-cycle
emacs_lisp => EMACS_LISP => EmacsLisp => emacs_lisp
In the case of string-inflection-elixir-style-cycle
emacs_lisp => EmacsLisp => emacs_lisp
In the case of string-inflection-python-style-cycle
emacs_lisp => EMACS_LISP => EmacsLisp => emacs_lisp
In the case of string-inflection-java-style-cycle
emacsLisp => EMACS_LISP => EmacsLisp => emacsLisp
In the case of string-inflection-all-cycle
emacs_lisp => EMACS_LISP => EmacsLisp => emacsLisp => emacs-lisp => Emacs_Lisp => emacs_lisp
It is recommended that the major mode functions are used instead of string-inflection-all-cycle
.

Region usage
You can also use this library to convert a region’s casing.
For that, simply select a region and perform M-x string-inflection-kebab-case
(or any such other function).
