Re: mac osx pdf point-and-click [was: mac osx emacs lilypond-mode]

[Sean Reed]

hi arjan,

this is my first real contribution to furthering knowledge on the list!
i've gotten the point-and-click to work on macos 10.3.9 with ly 2.5.23, 
but with a couple of ticks which you (or maybe han-wen or others?) 
could help me iron out.

the solution was to do everything in xwindows with x11 and not from the 
terminal.app (which you perhaps already knew?)

here's what i did:
1) i installed firefox from FINK to be run from an xterm in apple's x11.

2) i added the following lines to the prefs.js file in 
~HOME/.mozilla/firefox/vgftrus6.default/, with the full path to the 
lilypond-pdfpc-helper (not given on the lilypond website 
documentation):

user_pref("network.protocol-handler.app.textedit", 
"/sw/bin/lilypond-pdfpc-helper");
user_pref("network.protocol-handler.warn-external.textedit", false);

3) i installed Xpdf using FINK

4) i added the following line to the xpdfrc file in /sw/etc/; again 
note the full path:

urlCommand     "/sw/bin/firefox -remote 'openURL(%s)'"

5) i modified the editor search in the lilypond-pdfpc-helper binary in 
/sw/bin/ to read (again note the full path):

if ly_pc_editor == None:
        if  re.search ("emacs", editor):
		ly_pc_editor = '/sw/bin/emacsclient --no-wait +%(line)s:%(column)s 
%(file)s'

6) i then start apple's x11, and start /sw/bin/emacs from an xterm 
(this is one point where you may be able to help me: i can't figure out 
where to set the commands for the xterm so that i can just type "emacs" 
and have it automatically prepend the /sw/bin/)

7) you have to start the emacs server with M-x server-start

8) in a new xterm i then select emacs as the EDITOR using: export 
EDITOR="/sw/bin/emacs" (this is the next point you may be able to help 
me with. when i just enter "export" i see that, for example, the SHELL 
is set to bash etc., but no default for EDITOR. i can't seem to find 
the file to enter the EDITOR default, which is apparently, for example, 
the .profile file for the Terminal.app. I added export 
EDITOR="/sw/bin/emacs" to the bashrc file, but this didn't seem 
alleviate having to do it by hand in the xterm).

9) then i start firefox in a new xterm with /sw/bin/firefox

10) in another new xterm i start /sw/bin/xpdf

11) i load a pdf file made with ly2.5.23 into xpdf.

12) clicking on a note or other object now opens the corresponding 
lilypond file and takes me to A spot in the script. (it doesn't call 
emacs to the front though).

This final point is the tick, and may be where han-wen or somebody 
could add some advice. It takes me to the line and number as stated in 
the textedit:// hyperlink, but this is not the corresponding code for 
the given object. it is generally a line or two down. I checked to see 
if it had anything to do with lines which have been commented out, but 
it doesn't seem to. i'm wondering if it is different with a single 
voice lilypond file, but as yet have only tried it with multiple voice 
files.

In the hope that this may help you out a bit, and that we can find the 
last step in the chain to the correct position in the lilypond file!!

Best,
Sean

ps: my autoload still doesn't work for lilypond files in emacs, even in 
the xwindows environment. i'll keep trying to figure that out.
