evincelyxviewers
I am running LyX 2.0.2 in Ubuntu 12.04 and using the default PDF viewer Evince.
I want to setup SyncTeX to go back and forth between the document and the source, at the right position in the text.
I found this in the LyX website, but it doesn't give the Evince viewer.
http://wiki.lyx.org/LyX/SyncTeX
Does anybody know how to set it up?
I combined some of the links mentioned here, you will find the links in the source comments. This code supports:
C-c C-v)C-Mouse-1, that is Ctrl + "Left Click" in Evince); SyncTeX basics
; un-urlify and urlify-escape-only should be improved to handle all special characters, not only spaces.
; The fix for spaces is based on the first comment on http://emacswiki.org/emacs/AUCTeX#toc20
(defun un-urlify (fname-or-url)
"Transform file:///absolute/path from Gnome into /absolute/path with very limited support for special characters"
(if (string= (substring fname-or-url 0 8) "file:///")

Too long for a comment:
Importing the downloaded file into a non-UTF8 editor (like TeXnicCenter 1.0), reveals:
The first character could be the cause of the problem - called a Byte Order Mark. Even importing this into LyX 2.0.4 adds the following into the preamble (Document > Settings > LaTeX Preamble):
which you'll have to remove. Either remove this from the file first before importing, or attempt an update of your version from 2.0.2 to 2.0.4 and remove it after importing.

It seems there's no easy way to do this, yet.
Modifying Scripts
evincetoevince-synctex. (To be sure that this file will be started because/usr/bin/evincewill be found first inPATH.)Open this file (
evince-synctex) and replace the second line (starting withEDITORCMD) toIn file
evince_backward_search, replace the linecmd = re.sub("%f",input_file,self.editor)withBe sure that this text aligns with the text of the lines afterwards. (That change is needed because it seems that LyX can't handle filenames starting with "file://".)
Move all three files (
evince-synctex,evince_backward_search,evince_forward_search) to/usr/local/bin(needs root rights). (That's the place where user scripts should be stored.)Extra for Evince 3.4.0 (= Ubuntu 12.04)
In file
evince_forward_search, replace the last line (starting withwindow.SyncView() withSetting up LyX
