commit b7f4afe86c36c36a751cb9dd31daa69051eec506
Author: Rohit Patnaik <quanticle@quanticle.net>
Commit: Ihor Radchenko <yantar92@gmail.com>
lisp/ox-md.el: Add top level header setting
* lisp/ox-md.el (defcustom org-md-toplevel-hlevel): Define the customizable
variable that defines the top level heading to use when exporting to
markdown.
(org-export-define-derived-backend): Read the value of the new
`org-md-toplevel-hlevel' variable into the `:options-alist' for this backend
(org-md--build-toc): Use the newly defined top-level heading setting to
control
the heading level for the "Table of Contents" text.
(org-md-headline): Use the newly defined top-level heading setting as an
offset
to the heading level calculated by `org-export-get-relative-level'.
This patch adds a new setting: `org-md-toplevel-hlevel' that controls which
Markdown heading level is used for top level headings. This change makes
markdown export more like HTML export, which has a
`org-html-toplevel-hlevel'
variable which does the same thing for HTML export.
