5.8 Point and click

Point and click lets you find notes in the input by clicking on them in the Xdvi window. This makes it easier to find input that causes some error in the sheet music.

To use it, you need the following software:

Xdvi must be configured to find the TeX fonts and music fonts. Refer to the Xdvi documentation for more information.

To use point-and-click, add one of these lines to the top of your .ly file:

     #(ly:set-point-and-click 'line)

When viewing, Control-Mousebutton 1 will take you to the originating spot in the .ly file. Control-Mousebutton 2 will show all clickable boxes.

If you correct large files with point-and-click, be sure to start correcting at the end of the file. When you start at the top, and insert one line, all following locations will be off by a line.

For using point-and-click with Emacs, add the following In your Emacs startup file (usually ~/.emacs):

     (server-start)

Make sure that the environment variable XEDITOR is set to

     emacsclient --no-wait +%l %f

If you use XEmacs instead of Emacs, you use (gnuserve-start) in your .emacs, and set XEDITOR to gnuclient -q +%l %f.

For using Vim, set XEDITOR to gvim --remote +%l %f, or use this argument with Xdvi's -editor option.

For using NEdit, set XEDITOR to nc -noask +%l %f, or use this argument with Xdvi's -editor option.

If can also make your editor jump to the exact location of the note you clicked. This is only supported on Emacs and VIM. Users of Emacs version 20 must apply the patch emacsclient.patch. Users of version 21 must apply server.el.patch (version 21.2 and earlier). At the top of the ly file, replace the set-point-and-click line with the following line:

     #(ly:set-point-and-click 'line-column)

and set XEDITOR to emacsclient --no-wait +%l:%c %f. Vim users can set XEDITOR to gvim --remote +:%l:norm%c| %f.
