Hello,
I am reporting a bug in the core export engine of Org 10.0-pre where the
`#+TITLE` directive is parsed correctly but subsequently dropped by
`org-export-get-environment`. This causes export backends (such as HTML) to
generate an empty `<title>‎</title>` tag and completely omit the
document title from the output.
Steps to reproduce:
1. Start Emacs without configurations: `emacs -Q`
2. Create a file named `test.org` with the exact following content:
#+TITLE: TEST FILE
* header
lorem ipsum dolor sit amet
3. Parse the buffer using `M-: (org-element-parse-buffer)`. The AST
correctly identifies the title:
(keyword (:standard-properties [...] :key "TITLE" :value "TEST FILE"))
4. Evaluate the export environment: `M-: (plist-get
(org-export-get-environment) :title)`
Expected result:
The evaluation should return the parsed title list, e.g., `("TEST FILE")`.
Actual result:
The evaluation returns `nil`. The core framework fails to pass the title to
the export environment.
I would appreciate your feedback on this regression in the export framework.
Regards,
Kaan I. Yesilyurt
