Description

This layer adds support for rebox2 package which is a minor-mode allowing to easily add ASCII text boxes to a buffer.

A nice video demonstration by the package author can be found here.

Features

Auto-wrap correctly in comments,
Auto-fill correctly in comments,
Boxes auto-adapt as text is inserted or deleted,
S-return to continue a comment on the next line,
Kill/yank within the box,
Apparently works well with ancient filladpt-mode (see authors video).

Install

Layer

To use this configuration layer, add it to your ~/.spacemacs. You will need to add rebox to the existing dotspacemacs-configuration-layers list in this file.

Configuration

Styles cycling

Box styles are identified by numbers, it is possible to cycle through a list of styles using SPC x b n. This list can be customized by setting the variable rebox-style-loop.

(setq rebox-style-loop '(71 72 73))

Text mode

As text mode usage could surprise some users (e.g., when they enter M-q to fill a paragraph) rebox is not enabled by default in text-mode. To enable it you need to set the layer variable rebox-enable-in-text-mode to t.

(setq-default dotspacemacs-configuration-layers '(
    (rebox :variables rebox-enable-in-text-mode t)))

Style Templates

Standard packaged templates

Comments

These templates are single line comments styles. A # is used here for illustration; however, it will work equally well if the comment character is different (e.g., lisp's ; comment character).

  #box-style 10

  # box style 11

  # box style 12 #
