elyxer was last updated at the time LyX 2.1.n was the stable release,
hence it fails with features in the lyx file format that are more recent.

I was able to fix some/most issues by adapting the settings:

In Tools>Settings>File Handling>Converter I set up a converter

from: LyX 2.1.x
to:   HTML (elyxer)
converter: elyxer --nofooter --html --directory $$r $$i $$o

Now, file>export>HTML (elyxer) uses the route LyX > LyX 2.1.x > HTML

Have a look which characer in the document is responsible (evt. deleting 
or commenting part by part).
It may also be an unprintable character that somehow crept in.

If it is something like Greek or some other non-latin character, you should
switch to a font with wider coverage than LatinModern. Which one depends on
the side conditions like used packages or math content, personal taste,
type/audience of the document, ... Debian provides a wide range of free fonts.

Instead of modifying the existing layout, I recommend writing an additional
one that builds on it. This way, changes/fixes to the original will not be
masked by your local version.

I have e.g. in "~/.lyx/layouts/gm-lists.module" the code below.

However, the "Child Document" dialogue seems to be LyX-native
it allows to select the Include Type, has "Browse" and Edit buttons

I am working on Linux and use the "evince" document viewer to view the
PDF on-screen. The viewer supports printing and the print dialogue offers
the choice of several printers which includes the virtual printer "print
to file". It also provides for the selection of the pages to print, so it is
all just point and click for me.

Alternatively, LyX supports Insert>File>External Material>PDF pages.

It should work with "includeonly" if you have a Master document that includes
the existing documents source(s) + the new appendix.
After a first run which includes all sources (to get the references right),
you may exclude the main document and re-compile.

However, I would rather print the last 50 pages of the combined document to
a file and upload this.

In any case, you may have to add some advanced LaTeX code to restart the
page numbers etc. or live with the appendix document starting at 801.

I think this is the better approach. Besides beeing more general, it
saves us from having to decide which "documentclass" the "no class"
should get or if we should raise an error with any attempt to compile
this "no class"-document.
A "don't warn about different documentcalss" button in the

Sorry for not beeing clear: I see the advantages of the quote inset and do
not want to replace them.

Instead my suggestion is to let the quote inset write literal characters
instead of macros or ligatures whenever possible.

Working with the exported LaTeX file may be a good idea, one layer less that
may confuse things.

If you have an old LyX version lying around, you may also try this. Evt.
also export to LaTeX with the old version and re-import into current LyX.

It may be due to a lyx2lyx problem, some mistake when converting the
document from an old lyx format to the current one.

Keep the original file, and from a copy remove parts until it compiles.

I see: 

* The Unicode literals are used in the LaTeX source when
  
  - input uses Unicode literals (with either system key-combinations or
custom LyX keybindings) and

  - Document>Settings>Language>input encoding is set to one of the Unicode
encodings or "pass-through".

  or with "non-TeX" fonts.

* the "quote inset" still uses the LaTeX ligatures instead of Unicode with
  8-bit TeX fonts. 
  
  This was sensible with "input encoding" defaulting to latin1 (or some
  other language dependent 8-bit encoding) where the literal charater "“"
  would have become "\textdblquote" in the LaTeX source.
  As the new default "input encoding" is utf8, this reason no longer holds.

Could you file an enhancement request ticket at bugs.lyx.org?

With Unicode (utf8) encoding, there should be no need for \texorpdfstring, as
the typographical quotes are used in the latex source:

 >> \section{“Test”}

(This is one of the reasons why utf8 is the new default encoding in LyX 2.4.)

Which keys or key-combinations do you use to insert the quote signs?

By default, the »"«-key, inserts an "outer" „smart-quote inset“ which is
converted to a typographical quote according to the document language's
conventions (configurable in Document>Settings>Language).

The default binding for "inner" „smart quotes“ is Alt-". Alternatively, you
can use the Menu Insert>Special Character>Inner Quotation Mark.

The ` and ' keys, in contrast default to inserting ASCII GRAVE ACCENT
and APOSTROPHE respectively. Most LaTeX fonts show them in the shape of
typographical curly single quotes but most fonts used in web browsers show
them in the "neutral" shape.

> Also, when exporting to html, all quotes are properly converted, 

Probabely, the external converter implements a "smart quotes" feature.

I suppose with "xhtml" you mean the native "LyXHTML" export route?

There is no plan to add such a smartquotes feature to the LyXHTML export,
rather users should input typographical quotes either as literal characters
or "quote insets".

You may consider binding the '-key or the `-key to "quote-insert inner"
(with Tools>Preferences>Editing>Shortcuts),
use Alt-" or your systems keybindings for the literal curly quote Unicode
characters.

This is because in older versions of the inputenc package, the literal
characters were not supported.

You may try to copy the file "unicodesymbols" from the LyX library directory
(here /usr/local/src/lyx/lib/) to your personal lyx directory (here ~/.lyx/)
and comment out the lines

#0x201c "\\textquotedblleft"   "" "" # LEFT DOUBLE QUOTATION MARK

More probabely, one updated package (embrac, one of its dependencies or some

which generates the error. Looking at the first line(s) of the LaTeX log

Also, while the preamble line

wise to include it to clearly mark the intended encoding.

It is a problem in LyX, which loads the "esint" package for the double
integral automatically.

You can fix this in your document in Document>Settings>Math Options:
select "do not load" for the esint package.

This limitation is lifted in LuaTeX, so compiling with LuaTeX instead of
pdfTeX is a possible solution.

In principle, LuaTeX works fine with traditional TeX fonts and LuX supports
this well. 

However, some 3rd party packages check for the TeX engine
(pdftex/xetex/luatex) and assume Unicode-encoded "non-TeX fonts" are used
with the latter two. This may lead to errors in complex documents.

You can open the /tmp/ directory from the full log dialogue window:

 * in the error popup click: !show full log" button
 
 * in the full log click "open temporary directory" button
 
This should open the dir in a standard file browser.

Yes. 

This also happens if you close and re-open the file (or, if this fails LyX).

You may try the "enumitem" module and customize the lists, but it is
possible that this will not help because of a clash with the beamer list
redefinitions.

Then, changing your lists to not use so many levels or using simple
paragraphs on excessively nested parts is the only way out that I know of.

With this setting, you change the language declaration, i.e. you tell LyX
which language's conventions to use when processing the document. This
influences hyphenation, auto-generated text parts and spell-checking but
does not traslate the literal text.

Sometimes, even more changes occure, e.g. changing

It may help to have a look a the "enumitem" module that enhances enumeration
environments. 

The appended gm-lists.module requires and uses enumitem to define
additional list types. It is a bit dated, though.

You may try with another "engine", LuaTeX is known to be the slowest option.


Another idea is to split the document and "include" (not "input") the
parts. For the work on some part only compile this part with
"\includeonly". This keeps cross-references kind of up-to-date when
compiling the complete document every now and then.  A bit complex
but it helped me a lot when working on a specific chapter of the thesis.
(Read about the details in a LaTeX documentation.)

This mechanism was invented exactly for combating long compilation times
during the editing of large documents in the early LaTeX years where
computers were small and slow.

The *font* must not be confused with the LaTeX *input*
encoding (encoding of the *.tex source file).

The font encoding uses special names, valid values are "T1", "OT1", ...
(see `texdoc fontenc`). 

The encoding for Unicode-fonts (with Xe/LuaTeX and the "fontspec" package is
"TU" (earlier versions used "EU1" and "EU2"). But this is not used by LyX.

However, this setting is a legacy from the LyX change of the legacy OT1
encoding to the still old T1 and should be best left unchanged. 

You may set the font encoding in special cases per document with

Does this document use "non-TeX fonts"? Then the "default_fontenc" setting

Commercial mathematical fonts matching Times are available from
Micropress with TeX support by the package tmmath: https://ctan.org/pkg/tmmath

The "newtx" package (https://ctan.org/pkg/newtx) is not just a workaround
but the recommended free maths font package to match Times text fonts.

Alternatively, you can use the "STIX fonts"¹ (either for both, text and maths
oder in combination with Times as text font.

With XeTeX/LuaTeX, you can use non-TeX fonts and unicode-math with, e.g.
TeX Gyre or STIX¹
https://ctan.org/pkg/tex-gyre-math-termes
https://ctan.org/pkg/stix2-otf

*Mathematicl* font setup is conceptually and functionally different from
*text* mode fonts.  Unless your document contains Greek text parts or

Actually, I just created and maintain the "substitutefont" package. It is
intended to combine matching 8-bit fonts for different scripts, because
quite often font developers for, say, Greek miss advanced Latin features
(letter ß or ð, say) while fonts for Latin have only basic or no Greek or
Cyrillic support.

You are right, Artemisia is not a lookalike.

  GFS Artemisia is a relatively modern font, designed as a ‘general

https://www.ctan.org/pkg/gfs, https://www.ctan.org/pkg/psgreek).

Again, you can also use XeTeX/LuaTeX with any Unicode (non-TeX) font that

You can get a rich choice of mathematical symbols/characters matching

For text, you can use the Times lookalike "Artemisia" from the Greek Font

The LaTeX tool for adapting a math formula to bold text style is switching to
the math version "bold" *before* the formula.
http://ctan.math.washington.edu/tex-archive/macros/latex2e/contrib/isomath/isomath.html#math-font-selection

The switch is valid until another \mathversion command or the end of the
current group (e.g. a section command argument):

\documentclass[]{article}
\begin{document}

\section{$\mathrm{H_20}$ \mathversion{bold} $\mathrm{H_20}$}

back to normal math version $\mathrm{H_20}$
switch to bold math version \mathversion{bold} 
test $\mathrm{H_20}$

\end{document}

Some symbols don't exist in a bold version, so it may become a strange mix
of bold and normal characters, though.


There are packages that allow to define a default command for each section,
so you can automate the math version switch. If you are using the
KOMA-Script document classes, see their documentation for details.

Hope this helps,

Now, if you change in the code preview the "viewport" (second drop-down list
on the left) from [Current Paragraph] to [Complete Source] or [Preamble
only], you will be able to see the LyX-written LaTeX preamble.

With Document>Settings>Fonts as

Roman:  Palatino
SansDefault
TT  Default
Math:   Automatic

I get the preamble:

\documentclass[english]{article}
\usepackage{mathpazo}
\usepackage[T1]{fontenc}
\usepackage[latin9]{inputenc}
\usepackage{babel}

i.e. there is no need for

> \usepackage{mathpazo}

in the custom LaTeX preamble (Document>Settings>LaTeX Preamble).

>> You can also try with setting Fonts>Mathematics: Times Roman New TX
> I tried this, but \lambda is not shown


Now found the difference: You put \lambda in \mathrm.

Unfortunately, support for upright Greek letters in mathematics is
limited in traditional TeX. Standard TeX and most mathematical packages
use either italic Greek characters or a text font without Greek letters
with \mathrm. This is why you get an italic lambda with LatinModern or
Times but a wrong (text) character with Palatino.

For background and details, see
http://mirrors.ctan.org/macros/latex/contrib/isomath/isomath.html#oml-font-encoding

Do you really want an *upright* Lambda? This would indicate a
constant value or a physical unit (see, e.g.
http://old.iupac.org/standing/idcns/italic-roman_dec99.pdf).

If you put only the "max" and the unit into \mathrm, everything should be
fine (except for the missing space between value and unit).

Otherwise, see
http://mirrors.ctan.org/macros/latex/contrib/isomath/isomath.html#how-to-get-upright-small-greek-letters
for options to get upright Greek in 8-bit LaTeX maths or use non-TeX fonts
with Xe/LuaTeX.

Mathptmx is used for Times Roman by default. It is a stop-gap measure
combining several fonts for maths.

Better support is gained with newmathtx: select

The \epsilon vs. \varepsilon problem is also solved when selecting the

We could offer conversion between ERT and Math insets.

The .sty file is a document style -- either a very very old
document class (for latex 2.09)
or a "package" (extension for another document class).

The .tex file is most likely a template document.

The .bib file is a bibliographic database

The .pdf is a documentation or the result of "LaTeXing" the template .tex.


For LyX, you may need a new "layout" or "module". This depends on the
content of the template .tex file: if the line starting with

   \documentclass
   
lists a standard document class (or one already supported by LyX) you have
luck and can simply try to import the .tex file into LyX.

No. This would go against the intended use of the

@+  To be used for mathematical variables where style variations

An Unicode-compatible option would be to underline emphasized text with
compose-characters, but I don't know whether this would be regarded a good
idea by the developers.

I could rather imagine export to a minimalistic markup format like
reStructuredText or MarkDown.

This is the Python module with the conversion functions for 2.2 <-> 2.3.

.pyc files are pre-compiled "object code" files. You don't need them, they are

lyx2lyx/lyx2lyx is the conversion script that should be called (e.g. with

a symlink to usr/local/src/lyx23/lib/lyx2lyx/lyx2lyx in my PATH, so that

Standard and backport Debian lyx packages assume that only one version of
LyX should be installed ont the system. They do not use a version suffix for
configuration data and user directory.


I use a debian packaged lyx for productive work and a home-compiled one (with
version suffix) for development.

It seems there is some installed package/program that depends on the
non-backport version of a library while lyx-backported depends on the newer,
backported version of this library. This may be solved by upgrading more
packages to the backported version.

I use aptitude to check and resolve such conflicts.

Here, if I chose Alt-feh, the generated HTML has no PNGs included (see

Fine, so this seems to work fine at least. I wonder why the PNG should
differ... Do you use custom fonts?

LyXHTML export works fine here as well and Firefox shows the dots at the
right hight and above the variables. (Display may be different in
browsers that have missing or deficient MathML support.)

Both;) It also depends on the symbol under the dot.

Does it look better in the PDF output of the same document?

How do you produce the HTML? elyxer or LyXHTML?

Why do you use PNGs? Nowadays most browsers support maths.

This is about Polyglossia and system fonts, so one may try this but it may

While Polyglossia is known for a lot of false positives when checking
character support, it is not to blame here. Polyglossia tests for script
support in the used fonts, relying on often missing information in the
font metadata and gives errors (not just warnings).
The "There is no … in font …" warnings are from TeX.

The problem is that currently, in LyX's Unicode translation file we use the
Latin transcription for Greek:

In the Latin transcription, "s" stands for "\textautosigma", which
depending on the next characters is printed as "sigma" or "finalsigma".
This is fine if you type Greek text using Latin characters but bad if in
a document you write a single literal "σ" and in the PDF you get a single
"ς". Therefore, LyX uses the "never-to-become-finalsigma" transcript "sv"
with the "LGR ligature break character" "v" (cf.
https://www.lyx.org/trac/ticket/4966):

 0x03c3 "\\textgreek{sv}" "textgreek" 
"force=iso8859-7;cp437;cp437de;cp865,mathalpha" "\\sigma" "" # GREEK SMALL 
LETTER SIGMA

That "v" is missing in Libertine LGR is a bug in this font. May be they call
it a feature, because the effect of a missing character is almost the same
as a "ligature break" character: it prevents ligating (fine) but
* it also triggers a warning
* there is a/no ligature break in the text if you copy-paste from the PDF.

LyX turns warnings about missing characters into errors for good reason.
Unfortunately this can give rise to false positives in rare cases.

We had a similar problem with Unicode fonts lacking the ligature break
character (u200C, ZWNJ). However, we cannot tell LyX to ignore missing
"v" characters (which stand for ZWNJ in the LGR font encoding but are
printable characters normally).

The proper solution is to use the LaTeX internal character representation
(LICR) in the Unicode translation file:

 0x03c3 "\\textgreek{\\textsigma}""textgreek" 
"force=iso8859-7,mathalpha" "\\sigma" "" # GREEK SMALL LETTER SIGMA

A patch is ready since some years but hold back because Greek LICR macros
were a new feature at this time. I believe it is time to apply the patch
now. It works stable on my local installation and fixes the problem + some
others.

This depends: If you use literal Greek characters in the LaTeX source, there
is no warning.

A simple workaround in LyX is to set the LaTeX input encoding to UTF-8:

 Document>Settings>Language>Encoding>Other: Unicode (utf8)
 
("Language default" does not work, because we force-convert sigma to
override inputenc's "iso8859-7.def" replacing it with "autosigma".

This will not solve the warning issue (the font itself is the same).
Nevertheless, it may be a good idea to update the font call once we can
safely expect users to have the new interface or after a test in the LaTeX
configuration.

I could reproduce:

LinLibertineT-osf-lgr is a font in LGR (logal GReek) encoding, so the
problem seems to be in a Greek text part.

The v is defined as a "ligature break" (\textcompwordmark in LaTeX)
in the LGR font encoding. It is, e.g. used to prevent sigma (σ) becoming a
final sigma (ς) at the end of a word.

It is missing in Libertine LGR. 
As the ligature break is an invisible character, it may be there is no
problem with you file. Just check Greek parts -- maybe combined with the
method proposed by Scott.

I used to have this problem with de-1901 (german) vs. de-1996 (ngerman) but

Still suffer from a related problem when copying a formula from an English

In addition, you can try to open lyx from a command line (x-terminal window)
and see if there is a more specific error message from lyx2lyx.

It is also possible to run lyx2lyx from the command line and configure it

with the complete path):

The view in PDF depends on the selected fonts rather than export route. I
get identic results with PDF (pdflatex) and PDF (ps2pdf).

You may experiment with different fonts, as well as checking the result of
drag-and-drop from the PDF. Here, it is
 ab'c de`f  with PDF(pdflatex) and ab' de`f with PDF(ps2pdf).

This is a feature of LaTeX fonts: the ASCII quote and backtick are mapped

Here, I get the "typographical" quotes u2019 and u2018 in a teletype

In case using Unicode fonts is not an option, you may also try the
"listings" package (Insert>Program listing) with the options

  upquote=true
  basicstyle=\ttfamily

in Document>Settings>Program listings. In a minimal document, you may
need to add \usepackage{textcomp} to the LaTeX preamble.


A a last ressort, you can use the macro \textasciigrave (instead of
\char18) in raw LaTeX (ERT).

Unfortunately not (at least not easily).

Let's look for workarounds:

xunicode is only added for phonetic symbols with Unicode fonts ("tipa"
emulation via Insert->Special characters->Phonetic symbols): you may
consider inserting phonetic symbols as literal Unicode characters instead.

Usually, loading a package twice means the second call is just ignored. Only
if there are different package options, this fails. 
Are you using options? What is the error message?

Does your document class try include/require "tipa" functionality?
Otherwise, it should not require xunicode with an up to date fontspec package.

I know that amsmath re-defines \dots to be context sensitive. It may be
that \numberwithin{equation}{section} interferes with this re-definition in
some way (in the version used by you) and the bug is solved in current

You may try to use \ldots instead of \dots or to update your TeX installation.

Yes. Different latex "flavours" accept different graphics formats:

`pdflatex` accepts PDF, JPEG, PNG, ... but no EPS

What is the original format of the picture 17ubar_pub?

If it is PDF or PNG, then try to export to "LaTeX (pdflatex)" and compile

The screenshot and it does not help. I don't have any idea about Mageia6.

But if reconfigure does not make "biber" appear, biber is not installed---at
least not in at a place where LyX can find it.

You may try in a terminal the commands `biber --help`
and `which biber` to see whether it works and where it is installed (if it
is).
  
Ultimatively, you should look for help with someone knowing Mageia and TeX

Making "biber" available in Mageia6 is not the task of LyX developers.
Maybe it is alredy available but not installed as LyX dependency, maybe it
is missing. Ask the distribution packagers or file a bug to Mageia6.

After installing "biber", you must make LyX aware of this: open LyX and run

You stumbled about a bug in LyX. 

In ERT, it prevents you from input of characters that required conversion by
LyX for LaTeX export (fine). 

Unfortunately, LyX is overly cautious here, e.g. with the "latex input
encoding" (Document>Language>Encoding) set to utf8, there should be no
restriction --- but I can only input latin1 characters, not the rest of
Unicode.

The LaTeX macro \delta (as any other Greek letter name) generates the
mathematical symbol. It is a "math mode command", i.e. it only works if
LaTeX is in "math mode" (inbetween $ $ or an equation.

In LyX, you could use Ctrl-L: $\delta$, but the better way is using mathed,
as you did here:

I agree that the errors are not right. They don't show up normally.

Maybe you inserted a literal Unicode delta δ into the "math square" or
you have some unusual document settings and/or incomplete LaTeX installation.
Hard to tell without a minimal example.

You may try again, evt. also with Alt-M G  or with the "Greek" math toolbar.


If you want Greek *text*, don't use math mode but
literal Greek unicode characters in text mode.

With XeTeX/LuaTeX, you need to set a font that contains Greek letters.

With pdfTeX, you need to install Greek language support. 
If the text language is set to Greek and TeX fonts are used, you can also
use the ASCII transliteration provided by Babel instead of literal Greek
characters.

I can reproduce both: (lyx 2.2.2 on Debian, XFCE, no clipboard manager)

Sometimes, select and middle-paste works, sometimes not!

* Short text parts without special markup work.
  Paragraph breaks work, too.
  ERT works.
  Layout list works.
  
* Footnotes in the selection -- fail
  Selection in a heading -- fail
  Line with Newline inset or Space inset -- fail

No error in the terminal, nor in xsession-errors.

This is true, because the older lyx version cannot reliably handle
features added in a new lyx version.

Exception: the last maintenance release of a major release can open files
from the next major release.

OTOH, you can export files to older LyX formats with File>Export...


Advanced users can also just install a new lyx2lyx script for the old lyx.

Probably, this is overwritten by babel. You may try with ERT in the

a) You can edit a *.cls (LaTeX document class) file with any text editor.

   You need to make sure the content stays valid LaTeX code, though.
   You may need to consult a LaTeX book or online documentation, e.g.,
   the starter "clsguide.pdf" that comes with every LaTeX distribution.

b) The cls file cannot be compiled directly, only documents using it can be
   compiled (this holds for both, LaTeX and LyX documents).
   
   To test your *.cls file, create a small LaTeX document and compile this
   "by hand".
   
c) LyX adds a layer, the *.layout file that is an interface between the
   definitions in the *.cls file and what you want to see in LyX.
   See Help>Customization for details.
   
Hope that gets you started. In case of problems, please ask giving a
*minimal* example and the error message.

It is a known limitation of most LaTeX mathbb fonts to only support
uppercase Latin letters.

Exceptions include STIX fonts, some Unicode math fonts
and the packages fourier, fouriernc, and mathbbol.
The "symbols.pdf" document may also help
try 
  texdoc symbols

  \DeclareUTFcharacter[\UTFencname]{x00C5}{\AA}
  \DeclareUTFcomposite[\UTFencname]{x00C5}{\r}{A}

It seems to be still in LyX but depends on the external program latex2rtf:

configure.py contains the code:

checkProg('a LaTeX -> RTF converter', ['latex2rtf -p -S -o $$o $$i',

This depends, it may be the layout (if the failure is specific to all

Thanks.

I see some differences comparing your custom keuchusten layout and the
current standard ones:

* version: 35  vs. 63

* in keuchusten:Standard
 
   ParbreakIsNewline 1

  missing in standard:Standard
  
I suggest, in order to be up-to-date to mimic a standard book layout and
instead of


  # basic definitions, adopted from stdclass.inc -
  # however, that include calls too many other inc's
  # we won't need.

and

  # the same, now from stdlayouts.inc - we could as
  # well CopyStyle from Quotation, but then we'd have
  # to live with an element in the dropdown menu we
  # don't need. hence, for the sake of perfection,
  # we go on foot.

use the same method as in handling stdsections --- delete unwanted style with
NoStyle.

After converting your custom layout this way, you may try again with LyX 2.2.
(There is a way to instal different lyx versions side-by-side...)
