[Lazarus] How to bundle HTML help to package?

[Vojtěch Čihák]

Hello,
 
I'd like to ask how to bundle offline HTML help to *.lpk package, to make key [F1] work.
 
I've created some units as a part of project and documentation (using FPDoc).
 
I created package, copied units and xml documentation there. I renamed xml headers (package name) and created html using console:
$ fpdoc --format=html ..... 
 
I set the path in Package dialog -> Options -> IDE Integration -> FPDoc settings / Search path to "docs".
 
Directory structure is:
 
$(PkgOutDir) ... pas, inc, lpk, lrs files
$(PkgOutDir)/docs ... xml files
$(PkgOutDir)/docs/html ... html files
 
When I start a new  project and I place component from my package there (project must be saved):
 
- when I hover identifier, Lazarus displays correct hint with desription, OK
- when I open FPDoc editor, it works too, when I place carret in Source Editor on identifier, OK
- when I press F1, Lazarus shows dialog: No help found for line 36, column 35 of /media/disk/v1/Projects/Test/packagehelp/unit1.pas
 
When I try to press F1 for other identifiers, it works. Example: TForm opens default web browser with online help: http://lazarus-ccr.sourceforge.net/docs/lcl/forms/tform.html
 
What should I do? 
 
Thanks.
