Hi all,

I am having a similar problem with a related package--xyling (it
relies on xypic, just has some extra macros for linguistic trees).

OS 10.6.8
LyX 2.1.2

File attached. When I hit ps2pdf to preview, the file just does not
appear, although LyX thinks it's successfully made a PDF. I can create
a pdf from a minimal file using Postscript, but something is wrong
with the PS2PDF script. Unfortunately, I cannot generate a PDF from my
more complex file using Postscript--that one also reports successful
file creation, but not PS or PDF appears.

Oh, and there is no cx folder in /var/folders on my system.

This is a temporary directory and the name is random. You can see the
start of in in the preference pane. The cx etc. referred to the path
in Dough's email post.

For normal preview operation you don't need to know it. The menu item
Document - LaTeX Log knows where to look for the log file. The View
Complete Log button does the same.

The preview problem of Dough is the inline display of code snippets
and the log of this is not that easily found.

XeTeX and LuaTeX both have command definition conflicts for xyling,
but I've had problems generating PDFs with the simplest files using
these methods since about 2.1 (both return an error about the \sups
command being already defined). Not using \sups in the test file, as
you can see.

The xyling_fail.lyx document works for me. The xetex_fail.lyx leads to
the \sups problem too. It goes away when removing \usepackage{tipa}
from the preamble. After this it compiles if one adds the missing
closing brace of the \newcommand{\rul} … definition.

Stephan,

Yes! going to document settings, fonts, and then unclicking “Use non-Tex

Now with that option unchecked, I cannot typeset my document using
command-R. I guess I can use other ways to view my output, though.
Do you know why command-R doesn’t work? Is there a way to fix that?

Dough,

in case of a Non-TeX fonts document Command-R is using the XeTeX compiler to
create the PDF.
Some content of the document makes it requiring this compiler. Without the
option checked
LyX uses the normal pdflatex compiler and e.g. some special foreign
characters or math symbols
are a problem here.

Before my update I did not encounter this, so something must be different
now!

This I cannot answer, sorry. But you're right - there must be the problem.
You've talking about your update to 10.9 Mavericks? Perhaps a python problem
indeed.
You may check the protocols inside the directory

/var/folders/cx/8z8j7c710t9gcfvtljxkvjkcgn/T/lyx_tmpdir.KZwQoCf15278/lyx_tmpbuf3

 Stephan, 
 
 Yes! going to document settings, fonts, and then unclicking “Use non-Tex 
 fonts…” solves the problem with displaying my diagram. Thank you. 
 Now with that option unchecked, I cannot typeset my document using command-R. 
 I guess I can use other ways to view my output, though. 
 Do you know why command-R doesn’t work? Is there a way to fix that? 

Dough,

in case of a Non-TeX fonts document Command-R is using the XeTeX compiler to 
create the PDF.
Some content of the document makes it requiring this compiler. Without the 
option checked
LyX uses the normal pdflatex compiler and e.g. some special foreign characters 
or math symbols
are a problem here.

 Before my update I did not encounter this, so something must be different now!

This I cannot answer, sorry. But you're right - there must be the problem.
You've talking about your update to 10.9 Mavericks? Perhaps a python problem 
indeed.
You may check the protocols inside the directory 

 /var/folders/cx/8z8j7c710t9gcfvtljxkvjkcgn/T/lyx_tmpdir.KZwQoCf15278/lyx_tmpbuf3


You have to look inside the directory you can see in the message window.
The interesting file is named like lyxpreviewZ33063.log or similar.

 Hi Dough,
 
 note the difference in the two calls: the 2nd one has an additional switch 
 --latex=xelatex.
 This may be caused by the XeTeX/LuaTeX setting in the document settings. 
 Perhaps you can live
 without it?

Dear Stephan, 

Sure. On my screen I see 
   X\ar[r] Y
Instead of 
X - Y
Normally, when I am editing my diagram I see my xypic code and when I place the 
cursor outside the editing area, the diagram converts from code to a picture. 
Now, I see my code, but I do not see the picture when I place the cursor 
outside the editing area. 
Does this help?

Normally, when I am editing my diagram I see my xypic code and when I place the

Now, I see my code, but I do not see the picture when I place the cursor

2014-10-14 Thread Lauen, Douglas L

Stephan,

Yes! going to document settings, fonts, and then unclicking “Use non-Tex 
fonts…” solves the problem with displaying my diagram. Thank you.
Now with that option unchecked, I cannot typeset my document using command-R. I 
guess I can use other ways to view my output, though.
Do you know why command-R doesn’t work? Is there a way to fix that?
Before my update I did not encounter this, so something must be different now!

Dear Stephan,

Sure. On my screen I see

Normally, when I am editing my diagram I see my xypic code and when I place the

Now, I see my code, but I do not see the picture when I place the cursor

Stephan,

Yes! going to document settings, fonts, and then unclicking “Use non-Tex 
fonts…” solves the problem with displaying my diagram. Thank you.
Now with that option unchecked, I cannot typeset my document using command-R. I 
guess I can use other ways to view my output, though.
Do you know why command-R doesn’t work? Is there a way to fix that?
Before my update I did not encounter this, so something must be different now!

Dear Stephan,

Sure. On my screen I see
X\ar[r] Y
Instead of
 X -> Y
Normally, when I am editing my diagram I see my xypic code and when I place the 
cursor outside the editing area, the diagram converts from code to a picture. 
Now, I see my code, but I do not see the picture when I place the cursor 
outside the editing area.
Does this help?

Sorry, no it doesn't help.  A minimal example is a complete LyX file.
See here: http://wiki.lyx.org/FAQ/MinimalExample

Thanks!
Doug

Hello! My xypic diagrams are not previewing in LyX. I can see the matrix with 
the code, but no nice WYSIWYG picture with nodes and arrows. The file compiles 
fine and the diagrams look good in the pdf. I have gone into preferences, 
look, display, display graphics is checked. TexLive is telling me that the 
preview Latex package is installed. I reinstalled preview and xypic packages 
anyway and that did not help. Other equations (e.g. \beta ) display fine. I 
would appreciate any advice or short term workarounds. Thanks! Doug

Hi Dough,

note the difference in the two calls: the 2nd one has an additional switch 
"--latex=xelatex".
This may be caused by the XeTeX/LuaTeX setting in the document settings. 
Perhaps you can live
without it?

Stephan,

Yes! going to document settings, fonts, and then unclicking “Use non-Tex 
fonts…” solves the problem with displaying my diagram. Thank you.
Now with that option unchecked, I cannot typeset my document using command-R. I 
guess I can use other ways to view my output, though.
Do you know why command-R doesn’t work? Is there a way to fix that?
Before my update I did not encounter this, so something must be different now!

It looks like python fails to process something…

Stephan,
My apologies. Here are two lyx files.
The one titled displays.lyx displays my diagram. The other one does not.

Doug,

that's better. But I have to say: both are working on my system -
a Mac with LyX-2.1.2 on OS X 10.8.6. I've noticed I have to click
somewhere sometimes to trigger the display of the preview snippet.

The two examples are different only regarding the \use_non_tex_fonts
and the \font_roman setting in the preferences.

What you can do to check for errors converting is to open the message
pane and enable the graphics conversion message. There you should see
the problem if one exists.
