Hi Alan,

A few weeks ago Steffen Wolfrum and myself reported the issue to Richard Koch who did some research and discovered the origin of the problem. He has written again the part of the code related to synctex and ConTeXt and will issue a new version where the problem is fixed.

In the meanwhile you can use a previous version of TeXShop (I use version 77 and I can send you a Dropbox link to download it, of you wish) where the syncing between the PDF result and the ConTeXt source works fine.

Best regards: OK

http://pages.uoregon.edu/koch/texshop/changes_3.html it's not clear to me why a newer parser lib would fail on an older synctex format (whatever the change is) .. sumatra pdf works (last updates ayear ago) works ok

synctex fails with lualatex on windows too. And it fails with with the luatex version 1.06 (which is now in miktex) but not with 1.04 (texlive).

I compared the synctex files of both and the problem is that the link to the main tex file is missing at the start.

The synctex files refers to a lot positions in input 0 but the file list starts with

Input:1:D:/MiKTeX2.9/tex/latex/base/article.cls

I added before this line

Input:0:G:/Z-Test/./test-utf8.tex

and then synchronization worked again. Imho this is a luatex bug.

(the texlive synctex starts with number 1 and not 0 Input:1:G:/Z-Test/./test-utf8.tex) i noticed this 0 /1 iusue too but it was ok in old viewers so mayeb that changed .. fwiw, nothing changed in luatex where we just take the syntex code as-is ... actually in sumatra starting at 1 is the only thing that works

what i did notice (quick test on linux) is that the error that pops up reports a missing source file and shows only the path part which looks like a biug in the parser to me there is not much documentation about the synctex file; actually, if an editor would call out to an external program to resolve the location in the file that would be more robust and easier to maintain, given the one-call-per-document there is not that much gain in using a library in the viewer; it would be easier to update and keep in sync with tex too as now one depends on updating a viewer Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------

I don't think that the 0/1 issue is a problem in itself -- but I think that the change of the numbering system introduced the real bug: That the line

Input:0:G:/Z-Test/./test-utf8.tex

is missing in the synctex file. ok, we have a fix for that (but it doesn't explain why context generated files make texshop unhappy)

Well I don't have a mac and texshop. And I don't have a viewer with the newest synctex parser (sumatra is from 2016).

But the synctex output of context is wrong in certain places. E.g. when I compile this:

\starttext

\input knuth

\stoptext

then the synctex file contains no reference to knuth.tex:

SyncTeX Version:1 Input:1:G:/Z-Test/test-utf8.tex Output:pdf

and synchronization fails in sumatra for me too. \ReadFile doesn't work either.

(I made this test with a context updated today).

Oh. Is the context problem due to the luatex bug I reported?

It looked different to me ;-) In the luatex bug the main file was missing but here inputs are ignored. for sure there was bug in luatex that skipped the very first entry (the main file);

Well not for me. As I wrote: \starttext \input knuth \stoptext doesn't add a reference to knuth.tex on my system.

Thanks Luigi for the link, but unfortunately the version 3.89 of TeXShop does not work for me (even with the magic line %!TEX useOldSyncParser put at the begining of the source file), while version 3.77 does the sync stuff as expected, even by opening an \input source file. I have put here https://www.dropbox.com/sh/68gfmzci1g67y5d/AABxdQ9sZsCiR9k6se_4zX0ga?dl=0 example files which can be tested with various versions of TeXShop. I don’t have versions between 3.78 and 3.87, but my experience shows that the syncing works between the resulting PDF file of a source file typeset with ConTeXt version 2017.11.15 22:08 and TeXShop version 3.77, while the syncing does not work with versions 3.88 and 3.89.
