## Summary:

  # Logos (logos.el)

  This package provides a simple approach to setting up a "focus mode"
  for Emacs.  It uses the `page-delimiter` (typically the `^L`
  character) or the `outline-regexp` together with some commands to move
  between pages whether narrowing is in effect or not.  It also provides
  some optional stylistic tweaks which come into effect when the
  buffer-local `logos-focus-mode` is enabled.  The manual shows how to
  extend the code to achieve the desired result.

Version 1.2.0 on 2024-09-03
═══════════════════════════

  This version introduces minor refinements to an already stable
  package.


The `logos-update-fringe-in-buffers' works with `enable-theme-functions'
────────────────────────────────────────────────────────────────────────

  It is possible to hide the fringes when `logos-focus-mode' is enabled
  by setting the user option `logos-hide-fringe' to a non-nil value. To
  make sure that the proper colours are applied when the theme changes,
  users must also set up the `logos-update-fringe-in-buffers' to run
  after the theme is loaded.

  In versions of Emacs before 29 there was no standard way to do this
  (my themes (Modus, Ef, Standard) have always had the relevant "post
  load" hook). With Emacs 29, users can now use the
  `enable-theme-functions' to make this work with all themes:

  ┌────
  │ (add-hook 'enable-theme-functions #'logos-update-fringe-in-buffers)
  └────


New `logos-hide-header-line' user option for `logos-focus-mode'
───────────────────────────────────────────────────────────────

  Users can now optionally hide the header-line when `logos-focus-mode'
  is enabled in the current buffer. This is done by setting
  `logos-hide-header-line' to a non-nil value and then enabling the
  mode.

  [ Remember to read the manual for all such options. ]


Documented how to conditionally toggle `org-indent-mode'
────────────────────────────────────────────────────────

  The `logos-focus-mode' operates in the current buffer to make the
  changes that are needed for a more "focused" editing experience. Here
  we extend it to work with Org's virtual indentation.

  It disables `org-indent-mode' when `logos-focus-mode' is enabled and
  restores it when `logos-focus-mode' is disabled.  The
  `logos-set-mode-arg' function takes care of the technicalities.

  ┌────
  │ (defun my-logos-org-indent ()
  │   (when logos-focus-mode
  │     (logos-set-mode-arg 'org-indent-mode -1)))
  │ 
  │ (add-hook 'logos-focus-mode-hook #'my-logos-org-indent)
  └────


Documented how to toggle the menu-bar, tool-bar, tab-bar, and tab-line
──────────────────────────────────────────────────────────────────────

  Continuing from above, the following code block below shows how to
  disable the `menu-bar-mode', `tool-bar-mode', `tab-bar-mode', and
  `tab-line-mode' when `logos-focus-mode' is enabled. If the given mode
  is already disabled, the corresponding function does nothing.
  Otherwise, it toggles the mode off/on when `logos-focus-mode' is
  enabled/disabled.

  ┌────
  │ (defun my-logos-hide-menu-bar ()
  │   (when logos-focus-mode
  │     (logos-set-mode-arg 'menu-bar-mode -1)))
  │ 
  │ (add-hook 'logos-focus-mode-hook #'my-logos-hide-menu-bar)
  │ 
  │ ;; Assuming the `tool-bar-mode' is enabled by default...
  │ (defun my-logos-hide-tool-bar ()
  │   (when logos-focus-mode
  │     (logos-set-mode-arg 'tool-bar-mode -1)))
  │ 
  │ (add-hook 'logos-focus-mode-hook #'my-logos-hide-tool-bar)
  │ 
  │ ;; Assuming the `tab-bar-mode' is enabled by default...
  │ (defun my-logos-hide-tab-bar ()
  │   (when logos-focus-mode
  │     (logos-set-mode-arg 'tab-bar-mode -1)))
  │ 
  │ (add-hook 'logos-focus-mode-hook #'my-logos-hide-tab-bar)
  │ 
  │ ;; Assuming the `tab-line-mode' is enabled by default...
  │ (defun my-logos-hide-tab-line ()
  │   (when logos-focus-mode
  │     (logos-set-mode-arg 'tab-line-mode -1)))
  │ 
  │ (add-hook 'logos-focus-mode-hook #'my-logos-hide-tab-line)

Fixed a malformed `cond'

  This was affecting the `logos-narrow-dwim' function in some cases.
