Re: Cannot block the swapping of Apple and Control keys (OS 10.6, LyX 2.0.2)

Re: install not finding classes in miktek

Furthermore, I just uninstalled lyx and miktex and reinstalled from the bundled 
installer. 
Same problem. 

Any clues at all???

error: cannot view file

Hi,

When trying to view a document in pdf I get:

...
Error: Cannot view file
----------------------------------------
File does not exist: 
/var/tmp/lyx_tmpdir.J57590/lyx_tmpbuf2/xxxxxxx.pdf
...

A process called pdfetex is started but just hits 100% cpu usage and 
nothing happens. I tried changing the tmp directory, reinstalled lyx, 
reinstalled tetex, deleted the .lyx directory in /home, but nothing works. 
The same thing happens when exporting to pdf or dvi.

Has anyone an idea how to solve this?

Thanks,
Marco

I discovered that it has something to do with the Table Of Contents. When 
removed it works again, inserting it and it doesn't.

Thank you, The Management.

Re: install not finding classes in miktek

OK, so now I reinstalled everything not in Program Files, thinking perhaps the 
UAC in Vista was causing the problem. I noticed as it was installing that:
checking for an HTML previewer...
+checking for "firefox"...  no
checking for a Postscript previewer...
+checking for "ghostview"...  no

this seems strange since these are installed on my system...WUWT?

checking for an OpenDocument/OpenOffice viewer...
+checking for "oowriter"...  no
why not check for libreoffice?

opening lyx...fingers crossed...

YAY....my classes are there!! thank god for small favors!!!!

Trouble with Egyptian Hieroglyphs

Hi

In the past I've happily used the CTAN Poor Man's Hieroglyphs package
from within LyX to produce very acceptable Egyptian Hieroglyphs.

The thing worked by simply putting into the preamble:
\usepackage{hieroglf}

Then you could use TeX macros such as \pmglyph{\HA}... and surround this
if you wished in
\cartouche{ ... }

But

With more recent versions of LyX (e.g. 1.6.4.2 on a Mac and 1.6.5 on
Linux) this seems to be broken,

I get the error messages:
command \cedover unavailable in encoding T1
command \uunderer unavailable in encoding T1

Any ideas how I should proceed?

The way I got into this originally was to copy the LaTeX file:
hieroglf-trypmhg.tex to a local directory
then import that into LyX.
That worked on earlier versions and after cleaning up the TeX a bit I
was able to use that as a template.
The import produces the same errors re encoding listed above.
When I look at the file hieroglf.sty I see that the uunder is defined as:

\DeclareTextCommand{\uunder}{OT1}[1]%
  {{\o <at> lign{\relax#1\crcr\hidewidth\sh <at> ft{29}%
    \vbox to.2ex{\hbox{\char21}\vss}\hidewidth}}}

There is a similar command for cedover. As you can see, they use the
encoding OT1.

How can I set LyX to use OT1 encoding (or is that undesirable)?

You can set the font encoding (called "latex encoding" by LyX) in the
settings:

 1.6.x only allows global setting under Utils>Preferences
 2.x   also allows per-document configuration

Generally, T1 encoding is preferable because it also supports accented
characters (like ü) which in OT1 encoding is built of 2 parts so that
copy/paste and search in a PDF (or PS) file do not work as expected.

Mark that with the use of the T1 font encoding, the Computer Modern fonts
are replaced by the (bitmap!) European Modern fonts unless you select a
different font (e.g. Latin Modern) for your document.

As a physicist, I'd say math import is the most problematic part of the
Word-LyX interaction now and most needed.

(But you realize that even without math, there are users that would like to
see the tool.)

Absolutely - I am working in biological sciences, and one can convince
some Journals to accept submission in LaTeX, but one can not convince
co-authors to use LyX ............

For me, scenarios 2 and 3 are the most important, and 2 would require
roundtrip conversion *with preservation of change tracking and
comments* would be *very* important! In addition, highlioghting should
also be maintained.

Agreed here - Section <-> Heading 1 and so on, formating of individual
words (referred as semantic formatting) has to be maintained (italics
for species names *very* important.

See above.

Agreed.

Also agreed - could be to image, from whatever source, and the
original one could be maintained in a special comment field behind, so
that on re-import this could be used? In Word, the LaTeX code could
even be edited.

Essential I would say.
Problem might be to maintain BiBeX.

Very imortant - see above.

Same here - testing, commenting: definitely available.

This could become an essential tool to further the adaptation of LyX.
