open-source handler is designed to help with editing local sources
when reading a document. To that effect, you can use a bookmark with the
org-protocol-project-alist maps URLs to local file names,
by stripping URL parameters from the end and replacing the
:working-suffix. For example, assuming you own a local copy of
https://orgmode.org/worg/ contents at /home/user/worg, you can
org-protocol-project-alist to the following
(setq org-protocol-project-alist '(("Worg" :base-url "https://orgmode.org/worg/" :working-directory "/home/user/worg/" :online-suffix ".html" :working-suffix ".org")))
If you are now browsing https://orgmode.org/worg/org-contrib/org-protocol.html and find a typo or have an idea about how to enhance the documentation, simply click the bookmark and start editing.
However, such mapping may not yield the desired results. Suppose you
maintain an online store located at http://example.com/. The local
sources reside in /home/user/example/. It is common practice to serve
all products in such a store through one file and rewrite URLs that do not
match an existing file on the server. That way, a request to
http://example.com/print/posters.html might be rewritten on the server
to something like
open-source handler probably cannot find a file named
/home/user/example/print/posters.html.php and fails.
Such an entry in
org-protocol-project-alist may hold an additional
:rewrites. This property is a list of cons cells, each of
which maps a regular expression to a path relative to the
Now map the URL to the path /home/user/example/products.php by adding
:rewrites rules like this:
(setq org-protocol-project-alist '(("example.com" :base-url "http://example.com/" :working-directory "/home/user/example/" :online-suffix ".php" :working-suffix ".php" :rewrites (("example.com/print/" . "products.php") ("example.com/$" . "index.php")))))
Since ‘example.com/$’ is used as a regular expression, it maps http://example.com/, https://example.com, http://www.example.com/ and similar to /home/user/example/index.php.
:rewrites rules are searched as a last resort if and only if no
existing file name is matched.
Two functions can help you filling
org-protocol-create-for-org. The latter is of use if you're editing
an Org file that is part of a publishing project.
