#+TITLE:    :editor word-wrap
#+SUBTITLE: Soft-wrapping with language-aware indent
#+CREATED:  August 25, 2019
#+SINCE:    21.12.0 (#1709)

* Description :unfold:
This module adds a minor-mode [[fn:][+word-wrap-mode]], which intelligently wraps long
lines in the buffer without modifying the buffer content.

** Activation
Word wrapping is not enabled by default.

Wrapping can be toggled in the current buffer with ~M-x +word-wrap-mode~. The
default doom bindings bind this to [[kbd:][SPC t w]] for ~evil~ users.

To enable wrapping in a specific mode, add it to the appropriate hook in your
~config.el~:
#+begin_src emacs-lisp
;; enable word-wrap in C/C++/ObjC/Java
(add-hook 'c-mode-common-hook #'+word-wrap-mode)
#+end_src

To customize the behaviour in a specific mode:
#+begin_src emacs-lisp
;; use a single indent in json-mode
(add-hook! 'json-mode-hook
  (setq-local +word-wrap-extra-indent 'single)
  (+word-wrap-mode +1))
#+end_src

To turn on word wrapping (almost) everywhere:
#+begin_src emacs-lisp
;; enable word-wrap (almost) everywhere
(+global-word-wrap-mode +1)
#+end_src

To disable global word-wrapping in a specific mode:
#+begin_src emacs-lisp
;; disable global word-wrap in emacs-lisp-mode
(add-to-list '+word-wrap-disabled-modes 'emacs-lisp-mode)
#+end_src

** Settings
Wrapped lines will be indented to match the preceding line. In code buffers,
lines which are not inside a string or comment will have extra indentation as
determined by ~+word-wrap-extra-indent~. The default is to increase the indent
by twice the major-mode indent.

The ~+word-wrap-extra-indent~ variable supports the following values:
- ~double~: indent by twice the major-mode indentation
- ~single~: indent by the major-mode indentation
- a positive integer: indent by this fixed amount
- a negative integer: dedent by this fixed amount
- ~nil~: no extra indent

This module also includes a global minor-mode ~+global-word-wrap-mode~ to
automatically enable wrapping in most buffers. Wrapping will not be enabled in
buffers whose major mode is marked "special", or are listed in
~+word-wrap-disabled-modes~.

The ~+word-wrap-text-modes~ variable lists modes which shouldn't have any extra
indentation, regardless of the ~+word-wrap-extra-indent~ setting. This is useful
for modes which are primarily text, such as ~text-mode~ and ~markdown-mode~.

The ~+word-wrap-visual-modes~ variable lists modes which should only enable
~visual-line-mode~ and not provide any prefix indentation. This is useful for
modes like ~org-mode~ which handle prefix indentation themselves.
