I would like to use Blender's interactive help functionality for my custom operators, i.e. RMB an operator's button and choosing Online Manual or Online Python Reference to link to my own manual and code documentation.

So, is there a way to set custom links for a custom operator's help options?

There are two functions that takes you to the docs:

# Blender docs

# Blender Python docs

It seems that they take their parameters from the property as follows:

doc_id = data.identifier + property_name

where the property has been created in this manner:

col.row().prop(data, property_name)

Those functions search the _manual_map for this doc_id. The manual_map contains by default the blender_default_map which is (prefix, manual_mapping ).

The prefix is simply 'https://blender.org/manual' while manual_mapping is dict you give it the something+doc_id (in this case bpy.ops) and you get the rest of the url
(url = prefix + manual_mapping[doc_id])

So to add you manual you create your addon_map:

import bpy

prefix = "https://myaddon.org/manual/"
my_manual_mapping =(
    ("bpy.ops.myaddon.*", "page_one"),
    ("bpy.ops.myaddon.something.*", "page_one/page_two.html")

def my_map():

  ret = (prefix, my_manual_mapping)
  return ret


bpy.ops.wm.doc_view_manual(doc_id="") will now take you to your site.

(Note: I have this in my addon: bl_idname = "myaddon.simple_operator")

There doesn't appear to be a way for us to include custom links on an individual operator basis.

There is a "mapping" table that exists in rna_wiki_reference.py that links internal naming to url creation which always uses "blender.org/manual".

For the python reference, WM_OT_doc_view in wm.py (line 988) uses "blender.org/documentation/blender_python_api" in it's calculation of a url.

Without our addon details existing in either location, we don't have access to those features. I don't know of any plans to extend that to addon developers.

If all your addon operators are in their own custom panel you could create an operator that opens a url to your own site and have an extra "help" button that links to your web page.

For now the only supported way to include links is in our addons bl_info. The two links we can use are wiki_url and tracker_url which are used in the preferences for the "Documentation" and "Report a Bug" buttons shown with the addons info.

bl_info = {
    "wiki_url": "http://myaddon.com",
    "tracker_url": "http://mybugreports.com",

enter image description here
