PDF-Editor Links in Windows

[Thomas Wilmot]

Hello everyone,

I just thought I should once again draw some attention to the PDF 
Document-Text Editor hyperlink bug which exists at least in Microsoft 
Windows.

There is a post archived here: 
http://lists.gnu.org/archive/html/bug-lilypond/2013-04/msg00055.html in 
which Phil concludes that this is in fact a bug, as the Windows installer 
does not create a functioning environment.

I posted a while back about the same issue here: 
http://lilypond.1069038.n5.nabble.com/PDF-Links-in-Windows-td181761.html

I ran into it again today, but seem to have made new progress!

I was again trying to follow the guidelines at this page: 
https://msdn.microsoft.com/en-us/library/aa767914(v=vs.85).aspx

I tried simply making a text file with .REG extension, then double-clicking 
to merge with the registry, but it didn't work.  When I dug in with the 
Registry Editor, the Guile scheme was there, presumably from the initial 
installation.

Anyway, after messing around with the registry for a while, I finally got 
the [editor] application I requested to open!

This means that all the links in the hyperlink chain are working but the 
last!

1.  The PDF viewer is recognizing and sending out the URI request properly.
2.  Internet Explorer is translating the URI, as described on the MSDN page.
3.  The registry is calling the editor application (or whatever application 
I tell it to)
4.  The Editor Application is receiving the message from MSIE and appearing 
when called for even though the slashes are the wrong way!
5.  The last step is the editor actually understanding the URI and handling 
it correctly.

All the people who have this working seem to be using Vim, Emacs, or some 
other crazy editor!
I just want any simple text editor to be able to understand the URI. I would 
personally like Frescobaldi to understand it (which is probably something I 
should go contact them about), but given that LilyPad is the text editor 
which is included with LilyPond, it would make sense for it to be fully 
functional out of the box, including the hyperlinking between the original 
and Gold standard PDF reader from the creators of the format (Acrobat 
Reader) and the LilyPond-included text editor!

It seems that some Unicode support has been gained by LilyPad since I last 
used it which is great! (hence the lilypad-ascii.exe version), though I 
think this hyperlinking is a much more basic feature! (At least for an 
English speaker :P)

I have attached a screenshot of the error message given by LilyPad for not 
knowing what to do with the URI.

Thanks,
     Thomas
