** Configuration Examples
*** Example 1
#+BEGIN_SRC elisp
(require 'string-inflection)
;; C-q C-u is the key bindings similar to 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))
(t
;; default
(string-inflection-ruby-style-cycle))))
#+END_SRC
*** Example 2
#+BEGIN_SRC elisp
(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 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
We will change as follows each type =C-q C-u= Place the cursor in the =emacs_lisp=.
In the case of =string-inflection-ruby-style-cycle=
: emacs_lisp => 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
The =string-inflection-all-cycle=, conversion often. However,
conversion occurs even when there is no need to lower-camelcase.
Therefore so difficult to use, is not recommended
** Function that can be used alone
