I wrote two almost identical files in plain tex and context. When I
generated the synctex file and ran `mtxrun --script synctex --list
x.synctex` I got this:
```
$ mtxrun --script synctex --list context.synctex
mtx-synctex | begin page: 1
mtx-synctex | end page: 1
$ mtxrun --script synctex --list tex.synctex
mtx-synctex | begin page: 1
mtx-synctex | [ 72 82 92 82] : 1 :
/home/nawordar/tests/tex/hello/./tex.tex
mtx-synctex | end page: 1
```
It looks like context generates an incomplete synctext file.
I can't say ... what is missing? Can you figure out what makes Zathura
unhappy?
The context synctex files are definitely less verbose because (1) we
avoid clutter, (2) omit auto-generated content like pagenumbers and so,
(3) collapse ranges (which we can do because we know what we're dealing
with), (4) don't compress (because it makes no sense), (5) ignore
styles, (6) also handle xml, etc. There have been some changes between
synctex 1 and 2 but I don['t keep track of that. Actually, if a 'call
some command' approach would have been chosen we could have better
readable files (in our case lua or so).

calling "mtxrun --script synctex ..." which not only removes the
dependency of a library (the dependency on mtxrun is ok as one has
context anyway) but also permits room for improvement (apart from not
being tricked by latex specific heuristics in the library)
But that would need a change in Zathura wouldn't it?
sure, so unlikely to happen soon (i have no influence on that)
(but it would have been a better approach anyway, not being dependent on
libraries that that depend on specific synctex versions in tex as well
as heuristics; basically now one needs a version of the editor/viewer
that matches a tex engine); one doesn't hard code a pdf viewer in an
editor either (btw, the script approach permits two way sync, so in
texshop one can go from pdf to source and source to pdf)
here with
\starttext

\stoptext
i get
