;;; --------------------------------------------------------------------------
;;; Commentary:
;;
;; The functions and macros defined in this file are used by pel_keys.el to
;; create specialized key bindings and to manipulate customization groups.
;; To have a name show up in which-key 'menu', a named function is required,
;; otherwise all we see is 'prefix' which is not meaningful.
;; The macros in this file help simplify/reduce the lines of code used to
;; create the key bindings for functions that open the customization groups
;; PEL configuration and for Emacs groups.
;;
;; The following lists the functions ('-'), and macros ('@') provided
;; and their calling hierarchy:
;;
;; @ `pel--cfg-emacs'
;; @ `pel--cfg-ext-pkg'
;; @ `pel--cfg'
;; - `pel-prefixed'
;; @ `pel--cfg-pkg'
;; - `pel--customize-groups'
;; - `pel--customize-group'
;; - `pel--group-isin-libfile'
;; - `pel--isa-custom-group-p'
;; - `pel--multi-file-customization-p'

======= ======================== ============================================
N value Content Method
======= ======================== ============================================
none Mode-specific PDF Open local PDF
1 Mode-specific PDF Open local PDF with PDF reader
-1 Mode-specific PDF Open GitHub raw PDF with default web browser
>= 2 Language/Syntax/Ref PDF Open local PDF
<= -2 Language/Syntax/Ref PDF Open GitHub raw PDF with default web browser
======= ======================== ============================================
The local PDF is opened according to the value selected by the
`pel-open-pdf-method' user-option; which defaults to the local
PDF viewer.
The sign of the numeric value identifies whether the local PDF
file or the corresponding GitHub hosted raw PDF file is opened.
However, if the user-option variable `pel-flip-help-pdf-arg' is
set, it's the other way around: the GitHub remote file is opened
by default.
To open the web file, the function uses Emacs default browse
mechanism specified by the user-option variable
`browse-url-browser-function' unless the user-option variable
`pel-browser-used' forces the use of a specific browser.
If your system default browser can not render PDF files directly
and downloads them, then you can force the use of the Firefox
browser (which renders PDF) by setting `pel-browser-used' to
`firefox'.
Using a browser that is capable of direct rendering of PDF
produces a much better user experience: you will be able to
quickly navigate through PEL documentation inside the browser.
The `pel-help-pdf' function determines the requested PDF topic by the key
sequence that led to the execution of the command. These key sequences
normally end with the F1 key."
