And why? LyX isn't WYSIWYG, so as long as the work area is readable,
why worry about its typography?

If you use non-TeX fonts, you must compile with luatex and lualatex
instead of xelatex. Check your LyX preferences for compiling.

Just so we're all on the same page, you know your attachment contains
no string "noto", right?

Not only that, but on my computer using LyX 2.3.6.1 on an up-to-date
Void Linux, your document works perfectly. But you knew that already.

In order to use Noto fonts, I took your document in LyX and did the
following:

1) On Document>Settings>Fonts I checked "Use non-TeX fonts.

2) Document>Settings>Fonts>Roman I chose Noto Serif [GOOG]

3) Document>Settings>Fonts>Sans Serif I chose Noto Sans [GOOG]

4) Document>Settings>Fonts>Typewriter I chose Noto Sans Mono [GOOG]

5) Document>View [PDF (LuaTeX)] to compile and view the result.

I've attached my doc with Noto fonts.

Maybe you'll get lucky and my file will compile. Try it.

>I tried to report a bug after 5 years of having used your bug tracker
>for the last time and I found that:

Bug trackers are where bug reports go to die. On a lot of projects I
tried using their bug tracker, and the bug never got addressed because
putting in the bug tracker is like sweeping it under the table.

Half of the 50 free softwares I use have bug trackers, and they're all
different. I'm expected to learn and remember 25 different bug tracker
interfaces. I can't accuse LyX of this because I never submitted a LyX
problem to a bug tracker.

Bug trackers ALWAYS ask questions that are n/a for the problem being
reported, and occasionally you find one that *demands* an answer before
letting you go on.

When I was the Vimoutliner maintainer, we fixed problems that came in
on the mailing list, right away. Either we helped the user get it right,
or if it was a bug we fixed it and released. Everyone was happy. The
point could be made that our application was rather simple, but a) We
had only two developers, both very part time, and b) Maybe that's the
point: If the software's too complicated to handle on the mailing list,
maybe it's just too complicated.

One time I put on the mailing list a way to make the first new
paragraph non-indented, the rest indented, in HTML, so in the HTML
export they didn't need to do that mickey-mouse technique of two
different paragraph styles, one for the first paragraph and the other
for the rest. By the way, my solution was about 5 lines of CSS. Did
anyone thank me? No. They said "put it on the bug tracker." I said "I'm
not familiar with the bug tracker, can one of you do it?" The response
I got was that I was a lazy free-rider.

Bug trackers really do suck.

Sure you can. Reduce it down to your own MWE, and then replace the

Hi Neal,

I gave up on Computer Modern fonts years ago, because they're so thin
as to be difficult for a poorly sighted person to read quickly. Whether
"use non-tex fonts" is checked or not (it might be worse one way or
another, but it's not good either way). I now use exclusively (for
normal purposes):

* TeX Gyre Schola for normal serif fonts.

* TeX Gyre Heros for normal sans-serif fonts.

* TeX Gyre Cursor for monospaced fonts.

These fonts are readable, at a glance, on paper or on screen. They look
good, at least to me. All you do is install them from CTAN, check "use
non-tex fonts", and compile with LuaTeX and LuaLaTeX.

Once in a while I use Ubuntu Condensed when needing condensed fonts.

Note that if it's to be read exclusively on a screen (HTML or ePub), I
don't specify fonts, so that the user's preferences rule.

Your first step is to copy the document and reduce it to an MWE. An MWE
is the tiniest possible document that still reproduces the symptom.
Armed with the MWE, you can either troubleshoot it yourself or actually

How to reduce code lineheight in LaTeX Beamer

[Steve Litt]

Hi all,

I'm using Beamer straight with LaTeX (no LyX). There's too much space
between lines of code, so it makes the code hard to read and also
pushes other content down too far. The following is a frame from my
presentation:

\begin{frame} [fragile]
\frametitle{How to Design BNF}
\begin{semiverbatim}
wholefile ::= chunk | wholefile chunk
chunk ::= paratext multinewline
multinewline ::= NL NL | multinewline NL
\end{semiverbatim}
\end{frame}

How can I reduce the space between lines of this code?

Thanks,

Start by using grep on your LyX file. This might give you some ideas

LXQT is wonderful! I suggest that even though LXQT has a nice menu

Is your video card an nVidea? In the Linux world, friends don't let
friends use nVidea. Because of their ultra-paranoid secrecy on their
interfaces, the Free Software world has a very hard time making drivers
for their cards, and my experience is that their proprietary drivers are
intermittent and defective also. If you don't believe me, search the
web. If you have an nVidea graphics card, a simple change to Debian's
nVidea graphics drivers could be causing this, and good luck finding
the magic sauce to fix this intermittent.

If this is a laptop, you can't replace the video card, so your best bet
is to join MANY Linux User Group (LUG) mailing lists, and see if people
can help you find this year's secret sauce configuration for your
particular nVidea video interface.

If it's a desktop, I recommend buying yourself a nice Radeon or Intel
video card to replace your nVidea card or supplant your Mobo hosted
nVidea graphic interface, and then use the bios to turn off the
built-in. Either way, once you've gotten rid of your nVidea graphic
hardware, uninstall all the nVidea graphic software and drivers.

If switching out of nVidea doesn't fix the problem, that's fine, you've
improved your computer anyway, and you'll have ruled out a huge chunk
or X crash causes. I know this will be responded to by tens of people
saying their nVidea video interfaces work just fine. This is true, but
when nVidea graphic interfaces cause problems, they take days to
troubleshoot.

If you don't currently have an nVidea graphic interface, please
disregard this post.

I HIGHLY recommend Openbox. I've been using it for almost a decade and
it's perfect. A very similar window manager is ctwm, which I also
recommend. With either, I recommend using dmenu as your main program
launcher.

My personal opinion is it's much better to install texlive from the TUG
website rather than from your distro, because you can get everything
related to texlive at the TUG website. And whatever you do, never, EVER
install texlive from both TUG and your distro.

Hi Rich,

The fact that you're using double sided printing indicates to me that
your expected output format is paper. If the binding is at all stiff,
0.9" seems like too short an inside margin to me. 11pt is nice, but it
makes for some problems for those whose vision isn't correctable to
20/20. For those reasons I use 12pt or 14pt, but of course if you
expect your readership to be primarily young, 11pt is good. 11pt
would save a lot of printing cost compared to 12pt. I'm glad you didn't
choose 10pt.

I presume your choice of page size is done based on what book sizes can
be done for what price.

Bringing out a new book is always exciting.

Hi Rich,

I've done some research on this topic. Generally speaking, each line
should be a little less than 70 characters. If they get much longer,
the reader has a hard time going to the proper next line. If they get
much shorter, you get increases hyphenation and funky inter-word
spacing.

Beyond that, a lot of readability hinges on where the reader will be
reading. Paper? PDF on full sized monitor? PDF on mobile device? ePub?
Combination of preceding?

By the way Rich, if it ends up that you need a custom size, let's say 5
inches high and 3 inches wide to fit a mobile device, I can help you
with that, as I'm already doing it. My method works for the standard
book document class; you can translate it into KOMA, which I believe is
your document class of choice.

No problem. In your window manager or desktop or whatever, link an

Re: Ask for support for a small diploma work

[Steve Litt]

I'm a little confused about what's being asked, but if the goal is to
generate diplomas for people, Inkscape is a MUCH better alternative
than LyX. You put tokens in the diploma SVG file, run a simple
shellscript or Python or whatever to convert those tokens to the
current graduate from a list of graduates, and crank them out. Easy
Peazy, and with Inkscape you can align everything exactly how you want
it. I can't begin to imagine how horrible this job would be with LyX.

I can't understand why you want Inkscape in the equation at all. Your
best data is in your LyX/Beamer file(s), so why not just use that for
whatever you want?

The SVG standard has no provision for multiple pages. Inkscape has
added XML elements to simulate multiple pages, but it's pretty
squirelly. Please understand I'm a huge fan of Inkscape, recommending
it over LyX for flyers and the like. All the graphics on

Inkscape.

Forgetting what technology is to be used, what is it you want to

One man's opinion: When I use Beamer, I don't use LyX. From my
perspective, LyX adds more complication than convenience or capability.

I love LyX for long text documents, but for slide presentations,
letters, resumes and flyers, I think there are better ways to do things.

If this thing is really a poster rather than a multipage document, and
especially if it has pictures and text specifically placed in certain
places, I recommend Inkscape instead of LyX.

Hi Tim,

Either this is due to a slow computer or Klyx is slow.

A slow computer can be caused by a hardware problem, including bad
spots on your disk or a mostly full disk, or by resources gobbled by
other software. I can tell you that in my experience, KDE is a resource
hog. Also, most browsers are resource hogs, especially if they have a
lot of tabs open.

Slow Klyx can be caused by slow LyX or by the KlyX implementation being
slow.

The easiest test you can make is to save and archive a file that
exhibits this symptom, power your computer off, then power it on, and
before running anything else, open your saved file with Klyx. Leave the
archived version alone. Either the symptom gets less severe or it
doesn't. If it does, send us the output of:

lscpu
vmstat
df -h
lsof | wc -l

Those will help determine whether you're just too underpowered for KDE.

If the symptom is unchanged after powering off, install plain old LyX,
open the saved (not archived) file in LyX, and see whether performance
is noticibly better. If so, sounds like KlyX is a problem.

Just for fun, temporarily try using LXDE instead of KDE, and let us
know if it makes a big difference.

Bad idea. https://graphcom.com/type-1-fonts-discontinued-in-2023

Yeah, Adobe says somebody else will take over T1, and maybe that
will come to pass, but most people are going away from T1 now. No
matter what look you want, there will probably be non-T1 fonts to
achieve the look you want.

I'm going to get a lot of static about this, but in any serious
documents I place a compile shellscript in the directory and use that
to compile the LyX document and display it in *my* PDF viewer. So each
doc has its own compilation method, and when there are problems, LyX is
almost completely ruled out as a root cause. It's either something I
did or an unfortunate CTAN change.

Over time, as things evolve, usually for the better, I can alter my
compile script to take advantage of the changes. With my compile
shellscript, I can do a reconfigure every time with configure.py. I
name my shellscript something like jj so when it's time to recompile my
book I simply do ./jj  . After all, I'm already in the book's directory.

You can, and I suggest you try it just in case it works, but my
experience tells me that out of stack errors are caused by bad LaTeX
authoring, not a correct LaTeX file that just happens to need a little
more stack.

I know how to fix this. Archive what you currently have, copy it to
mwe.lyx, then start subtracting stuff until only the essentials of the
requirements to produce the error remain. Archive that file as mwe.lyx.
Then, with some experimentation, the root cause should stick out like a
sore thumb, and once you find it, you can fix it either by fixing the
root cause in the originally archived document, or by slowly building
up the fixed mwe until it becomes obvious how to fix the original file.

Even if this doesn't work for you, asking questions about mwe.lyx would
*greatly* increase the likelihood of somebody accurately answering your
questions.

I run into this hassle all the time. It's frustrating and time
consuming, but if you follow the process, fixing it isn't rocket
science.

Several years ago I de-installed the distro-provided TeXLive and used
only TUG provided TeXLive (with tlmgr), and I've been very happy ever

It's pretty easy to install several versions of LyX on the same
computer. I'd see if I could convert it using a LyX older than 2.4.0
Beta2, and if I can, then I'd try to convert the converted file to
2.4.0 Beta2. Obviously I'd back up the original file and back up at
each successful stage.

hvextern

[Steve Litt]

Hi all,

I just found out today that Herbert Voss has recently (starting about a
year ago) created software, called hvextern, that takes a separate
source code file, and turns it into an image file for inclusion in your
document. Here's a quote from https://ctan.org/pkg/hvextern?lang=en :

"This package allows to write METAPOST, TEX, ConTEXt, LATEX, LuaTEX,
LuaLATEX, XETEX, XELATEX, Lua, Perl, or Python source code into an
external file, run that file via shell-escape to create PDF, PNG, or
text output, and include that output automatically into the main LATEX
document."

This means that as the source code changes, you just rerun hvextern and
recompile your LaTeX document. I see no reason why this can't be used
in LyX too. If you're a technical author like I am, this just might be
a pretty big deal.

If you want a several-page detailed description of hvexern and its use
and capabilities, you can see Herbert's article at
https://tug.org/TUGboat/tb43-3/tb135voss-extern.pdf . It was included in
in TUGboat volume 43, #3.

All I'm saying is if the MWE doesn't reproduce the symptom, it's not a

Either your MWE failed to isolate the root cause, or there are two
(probably clashing or interacting) root causes and you only got one of
them. 

Just start with a copy of the whole document and subtract little by
little until something you subtract causes the symptom to disappear.
Then put that piece back in and leave that piece permanently in and
subtract other things little by little until the symptom again toggles,
and once again put it back in permanently. Continue until there's
nothing left to subtract.

I usually just have a shellscript to export to PDF or LaTeX, and if
LaTeX, compile it. Also deal with images needing conversion. Within that
shellscript I can set any directories I want to. I enjoy this method
because I know exactly every step of the conversion process.

:-)

Rereading, I see I didn't express myself clearly.

I found the answer to my badly expressed question. On the 
Document=>Document_settings=>Document_class window there's a checkbox
called "Use Refstyle (Not Prettyref) for cross reference". It was
checked. I unchecked it, the document compiled, and I couldn't find any
differences in the PDF, so I worked around the problem.

Everyone, if you have "Use Refstyle (Not Prettyref) for cross
reference" checked on the Document Class window, be on the lookout for
trouble if you have later TeXLive installations. I recently upgraded
from 2021 to 2023 a week or so ago, and I'm pretty sure that's why the
symptom appeared at about the same time.

My book isn't compiling, having something to do with refstyle

[Steve Litt]

One of my books, which a couple weeks ago compiled just fine, now
errors out as follows:'

Argument of \eqref has an extra }.

By MWEing the created TeX file and running LuaLaTeX on it, I found that
the problem disappears when I commented out \input refstyle , except
that *then* other problems happened. I found nothing about refstyle in
any of my document settings, nor in my layout file. Looking at my LyX
file in Vim, I found the following line:

\use_refstyle 1

So in the editor I changed the 1 to 0, saved and ran LyX again. This
time I got an error on almost every \ref, or at least about 10 of them.

So here are my questions:

1) Did something change about the refstyle package in the last few
weeks?

2) Did LyX make a change that affected how the refstyle package works?

3) Within the LyX user interface, where can I see the configuration
that affects the usage of the refstyle package?

Thanks,

Hi Tom,

Could you please attach a small, 2 slide example sliver of your

Exactly! You change the margins, and therefore the size of the text

This is true. I've used \paperheight and \paperwidth in some of my LyX

probably a better way to go.

Does long paper really require a change of doctype? I think you can do
what you need by putting the following two lines in your
Docuument=>settings=>Latex_preamble:


\pageheight=14in %Paper height
\pagewidth=8.5in  %Paper width


The preceding works as long as you compile with luatex, which is the
best way to compile anyway. I don't know about the AMS document type,
but my best guess would be it would accommodate the preceding.
Naturally you'd need to change all the margins in LyX, but that's easy.

If worst comes to worst, you could create a new document type,
based on whatever new document type you are moving to, in a layout
file, and just create new paragraph/subparagraphs environments.

Re: Fonts for LyX

Thanks Eckhard,

OK, so I downloaded the four fonts:

[slitt@mydesk VES]$ ls -l
total 484
-rw-r--r-- 1 slitt slitt  90264 Mar 28 23:17 CMRV11-Italic.otf
-rw-r--r-- 1 slitt slitt 139244 Apr  1 13:36 CMRV11-Regular.otf
-rw-r--r-- 1 slitt slitt  82044 Apr  1 13:35 CMRV11-Semibold-Italic.otf
-rw-r--r-- 1 slitt slitt 174576 Apr  1 13:35 CMRV11-Semibold.otf
[slitt@mydesk VES]$

Some questions:

1. Where do I put these four files so they're visible to my (CTAN
installed) TeXLive system yet not intermingled with TeXLive provided
fonts?

2. How do I install them? I assume I run texhash, but what else?

Thanks,

Can pdfTeX even make a .dvi? I thought pdfTeX skips the .dvi step and
goes right to PDF.

Anyway, stuff like this is why I use shellscripts to compile my LyX
files. I think they're called "batch files" or "powerscripts" in
Windows. Compiling with shellscripts, I'm not beholden to  LyX' current
settings, and it's a lot easier to debug a shellscript.

Re: Insert an empty line in beamer

>Any idea how to insert a (real) empty line in the editor?

I'm confused as to what you're trying to accomplish, and have no idea
what a "real" empty line is. I also don't know what LyX does to Beamer
(I use Beamer directly, without LyX), and I have no idea how the
Beamer macro package changes the behavior of normal LaTeX macros.

But I do know this about LaTeX: The following produces the phrase
"First line" directly over the phrase "Second line".

=
~\\[0ex]First line\\[1ex]Second line
=

The purpose of the ~\\[0ex] is so the next two lines aren't subject to
the paragraph's indenting. The distance between the lines can be
adjusted by modifying the 1ex. You can create a character style to
express the command above, and use that character so you wouldn't
need to use ERT. 

>What I do now is I insert an empty line with an ERT box.

If you're satisfied with the spacing your ERT box presents, it would be
almost trivial to create a character style that puts a box at the end
of the line.

Of course the later font load might screw up other things, and would
certainly need to be done before things start getting written to the
dvi or pdf.

The older I get, the more I wonder if LaTeX is really better than Plain
TeX. LaTeX has all sorts of conflicting packages, its Document Classes
are never exactly what I want, and in fact the two times I started a
book with anything but the Book Document Class (which I was forced to
modify heavily every time to get what I needed), all sorts of conflicts
popped up. 

It's true that LaTeX has zillions of packages that make hard things
easy, but those packages also require more layers of abstraction and
often cause conflicts.

Like LaTeX, Plain TeX can be used both as a markup language and a
Turing Complete language. Markup is easier with Plain TeX, and Plain
TeX is much more easily exported from styles-based XML, making it a
great component for a write once/deploy everywhere tool.

The hairiest thing I ever did in LaTeX was in my book "The Key to
Everyday Excellence", a teaching-fiction book in which the plot skipped
around in time so much that I set up LaTeX to write, in the page header,
the date on which the current page was taking place. Ha, little did I
know that ten years later it would be a hip thing to confuse the reader
or viewer as to whether something was current or back-story, and if the
latter, when.

Anyway, when I learn more Plain TeX, I'll be trying the date-in-header
trick in Plain TeX too.

I'm not suggesting LyX switch to outputting Plain TeX. It's about 25
years too late for a decision like that. I'm just saying it doesn't
surprise me that there's a question of changing when fonts are defined.

Type1 fonts now obsolete

[Steve Litt]

Hi all,

You probably know this already, but in January 2023 Adobe software
stopped supporting Type1 fonts. This means that any documents
containing Type1 fonts cannot be accurately depicted on the latest Adobe
software. This pretty much means Type1 fonts shouldn't be used.

Now I'll need to audit all my books, some of which were written in the
20th century, to make sure they don't use Type1 fonts, and if they do,
change to the closest possible Opentype or Truetype fonts.

I don't know if this would work, but just for fun try using luatex and
lualatex to compile. I think you specify luatex in one of the LyX
config windows. Luatex and lualatex enable you to do a lot more with
fonts than the other compilers.

I'm a huge fan of LuaLaTeX but it does have one disadvantage: It takes
(subjectively) about twice as long to compile a LaTeX document to PDF.

Most people don't care whether the occasional LyX=>PDF takes 30 second
or 50 seconds because they do this so rarely, but in my case my book
fulfillment process compiles the doc for every eBook emailed out. 

Because of this extra time, I haven't hurried to make *all* my books
compile with LuaLaTeX. Note that my finding is subjective and
anecdotal, so more info is needed.

LyX is great for writing books and other long documents, but I'd
personally recommend an outliner for making an outline. If you know Vim
and want simple, you can use VimOutliner. If you want the Cadillac of
the industry, you can use the Leo outliner.

By the way, when I write a book, I outline it in VimOutliner, and when
the outline's done, I run it through a simple program that turns the
outline headings into LyX headings, and the outline body text to
Standard paragraphs.

Re: MWE: two issues need resolving

[Steve Litt]

I'm taking the unusual step of top-posting because my comments pertain
to the entirety of Rich's post...

Rich, this was not a quality MWE. The map's PDF had a hard-coded path
that needed to be erased. Your bibliographies failed because you didn't
include ../jabrefdb.bib, or at least it didn't exist on my computer.
Given that your complaints didn't seem to involve your bibliography, it
would have made our lives easier if you'd removed your bibliography
reference, and also if your MWE operated from files in one directory,
and you tested to make sure only the asked-about problems were in the
MWE.

After taking the time to remove hard coded paths, get rid of your
bibliography entry (because no ../jabrefdb.bib), and set your
bibliography back to Bibtex(Basic), it compiled on my LyX Version
2.3.6.1, and by clicking your map image and checking the "scale
graphics" box and putting a number in the field to its right, I was
able to scale the map, on the resulting compiled PDF, to any size I
wanted to, including 75%, which didn't page feed.

If your LyX version is later than 2.3.6.1 then maybe the version change
accounts for your image scaling trouble. Otherwise, go back and make
your MWE a real MWE and keep narrowing it down until you find the root
cause.

Yes. A great place would be

I'll of course run it by all of you before modifying this wiki, but I
think references to old-timers and senile old buggers should be

posting is just a special case of interleave posting. Bottom posting is
compatible with interleave posting, whereas top posting destroys
interleave posting. I'll try to have the text, for the project's
approval, in a month.

The preceding sentence sounds great in theory, but in practice how do you

You know, the LyX project should have a prominent and obvious document stating 
the
following:

* Be nice, pleasant and helpful

* Interleave post

* Trim all irrelevant quoted context

* Before emailing:

* Do at least 15 minutes research
* Try to make a Minimum Working Example

Naturally, the whole concept of a MWE and instructions how to make one should 
also
be explained, probably as a link to "Try to make a Minimum Working Example". You
might even add that about 2/3 of the problems get solved without help if the 
person
makes a real MWE.

Also, interleave posting and context trimming should be explained.

Yeah, I was going to mention the top posting thing too. And if a person wants 
to use
Tikz in LaTeX to include geometric figures in their LyX documents and therefore 
asks
questions on the LyX list, only a wannabe list cop would object.

Absolutely true!

For more on making email communication easier and more straightforward, 
everybody
who speaks English should read the following document:

http://www.catb.org/~esr/faqs/smart-questions.html

Also, the LyX list was the list I remember that introduced itself to the MWE, 
the
minimal example necessary to produce the symptom. Using an MWE makes the cause
obvious to those in the know, and if your life is like mine, by the time you've
created the MWE, the root cause is obvious to you so you needn't post the 
question
at all.

I can add some things:

* Don't top-post in a group discussion: It breaks relationships between 
questions
and answers.

* Instead, interleave post, where you answer each question directly below the
question. This way all know which question the answer is answering.

* If you simply must top post in a group discussion, instead of using pronouns,
reproduce exactly what you're talking about. Those who top-post "I agree, and
furthermore the foo should come earlier" leave the ambiguities: 1) With whom 
does he
agree and about what, and 2) The foo should come earlier than what?

* When you email a lot of questions, anticipate top posters, and number your
questions so the top poster can at least use those numbers to link the answer 
to the
question.

* Nothing I've said here implies you shouldn't follow the usual and customary
business email standard of top posting in order to preserve every assertion and
cover everybody's ass.

* Whether you top post or not, remove all context quotes not relevant to what 
you're
saying. This makes your meaning much clearer, and removes the task of reading
through hundreds or thousands of moot words. The #1 argument FOR top-posting in
mailinng lists is people don't want to go through hundreds or thousands of words
just to get to what you say. This is a valid argument, but if you remove 
unneeded
context quotes this argument ceases to be a problem.

* For free software centric mailing lists, for gosh sakes use plain text, not 
html.

* Make sure your email client does quoting in a way that different peoples'
contributions are identified by indents or color or whatever their email client
does. There's nothing like reading an email with same-level quoting, in which it
looks like the poster is arguing with himself and you can't tell who said what.

By the way, most of what I mention above applies to any group discussion: email,
forums, slack, stackoverflow, or others.

ERT does (or did) indeed stand for Evil Red Text. ERT is the method for 
inserting
raw LaTeX into a LyX document. In 2001, when I first joined the LyX list and 
began
using LyX to write books, ERT was widely used, and eerybody referred to it 
as
ERT. Evil because it's usually not really the best way to do things. Red, 
because at
the time (and I think still) it was red within the LyX screen on which you type.
Text, because whatever text you put in would be interpreted as LaTeX.

LyX has progressed amazingly in the past 2 decades, so ERT is less necessary 
now.
ERT has a different and more descriptive name now, but I don't know what it is,
because about the only place I use ERT is in the frontmatter in order to get the
front cover graphic aligned correctly, and to guarantee a few pagefeeds. 
Because I
use it so little, I rarely talk about it. I never thought of it before, but I 
still
use the 20 year old phrase "ERT" instead of its modern name. I'm sorry for the
confusion.

If one prefers not to put it in ERT, a character style can be made that inserts
\degree, but ignores the actual text typed in. I did this with the book title 
for my
"Mental Model Construction Best Practices" book, because until the book was
completed I kept changing the working title and didn't know what the title would
ultimately be. Everywhere the ultimate title should appear, I typed  and 
applied
the ChartitleInBody character style I'd defined. Every time I changed the book
title, I just changed the LaTeX for that char style, and every reference to the
title in the book changed. The same can be done with \degree, if this is 
prefereable
to ERT.

Hi Pierig,

If you're saying you want every line of the first paragraph of a dialog between 
two
people to start with a hyphen or dash, I don't think that's possible in LaTeX 
or CSS
or pretty much anything.

So, are you really looking for the following?:

 - Steve said, "My skateboard went down a sewer, so I fished it out with a rope 
 - and coathanger. It took an hour, but it was better than climbing into the
 - sewer, because there was a dead, rotting aligator down there and about a
 - thousand rats feasting on it."

 "Pretty gross, replied Pierig. When my skateboard fell down the sewer, I just 
took 
 off the sewer cap and retrieved it. It only took me ten minutes. But there was
 no wildlife in the sewer."

 With a far off look in his eye, Steve said, "I remember the good old days when 
   
sewers didn't have rotting carcasses in them. Those were the days, when you 
could
get your skateboard just by climbing in!"

Is the preceding what you meant, because if it is, I can't think of one piece of
software that will do the preceding for you. If the preceding is *not* what you
meant, please give us a sample so we're all on the same page. By the way, my 
mail
client gives me very little control over indentation, so please ignore the
indentation and concentrate on where the dash/hyphens go.

Thanks,

I think you're going to be quite pleased with making your own text types 
(LyX-speak
"environments") instead of hijacking environments meant for other purposes. 
You're
moving from two to three, but if your books are anything like mine, now that 
you can
make your own types, you'll want more of them. Just as a for instance, you have
dialog and thoughts, but what about narration? What about narration of stories 
and
back stories? When you can make your own environments, the world is your oyster.

I congratulate you on choosing Book class. It works with everything, and it's 
very
adaptable. 7 of my 9 books use Book class, and I'd never again use Koma or 
Memoir.

I'm confused about the preceding. Are you intending to insert ERT code "/item"

I suggest you find the LaTeX source for the Book document class standard 
paragraph.
I don't remember where it is, but other people do. Modify as needed for each of 
your
desired environments.

Having the first and last whatever different from the middle ones might require
three different paragraph styles. I think LyX has a "next style" property you 
can
put in the LyX part of the environment definition, so that pretty much makes
everything except the last whatever automatic.

Here's a doc I wrote 13 years ago discussing making your own layout file:

http://troubleshooters.com/linux/lyx/surefire_layout.htm


Also read http://www.troubleshooters.com/lpm/200210/200210.htm . It's almost 20
years old, but it has ways to modify existing LaTeX environments without 
rewriting
them from scratch. Combined with CopyStyle, this just might simplify your task.

If you ever need to make your own list environments, see
http://troubleshooters.com/linux/lyx/ownlists.htm

Actually, you might want to acquaint yourself with my whole LyX subsite,
http://troubleshooters.com/linux/lyx/ , which links to quite a few LyX 
documents.

Hi Wolfgang,

What El wrote is a shellscript. Shellscripts can't be used on Windows unless you
have Linux For Windows or Windows Posix or whatever. "realpath" is an actual
shellscript command that resolves the true path/filename regardless of symlinks.

So basically, for every directory name listed on the "for" line, delete the real
filenamename associated with the first occurence of the list item that occurs 
first
on the executable path.

I'm personally not a fan of mass deletion inside a shellscript. If it were me, 
I'd
substitute the line currently saying rm -rf $(realpath $(which $i)) with:

echo $(realpath $(which $i))

That should give you a list of the true filenames to delete. I'd then check 
each one
before deleting it manually.

Also, if these are just executables and you installed them via a package from 
your
distribution, the executables will "come back" the next time you get an update 
for
the particular version. But I don't know your situation.

Hi Wolfgang,

This is not responsive to your question, but in the past I tried Memoir once and
Koma once for books. My findings were that they conflicted with things and 
weren't
worth the hassle just for a snazzier look and feel you can probably make 
yourself
anyway.

Nowadays I use a layout file, based on the Book document class, for every book. 
I
can get pretty much any look I want.

Or, how's this for a novel idea: How about discussing bugs on the

it and many voices can effortlessly narrow it down. This will weed out
the "defective user" caused bugs, and will produce a pinpoint accurate

I can't speak for Windows, but in Linux I use shellscripts to compile
all my books, and it works perfectly. I just run the shellscript and it
runs lualatex, and watermarks my PDF. It could just as easily run a
postprocessor. If I wanted to make it "one click", I'd just assign it
an icon on my desktop. 

I hear Windows has Powerscript now.

If manpower's so short and it's moving so slowly, perhaps we should just
fix things post-conversion. I have about 3 hours a week to devote to it,
and I'm pretty conversant with the xml.etree.ElementTree XML parser for
Python. It sounds like you know what should go in an HTML/ePub
document. If we get a couple more people with Python and document
expertise, we could fix this, as long as the LyX->HTML export remains
well-formed XML.

I bet maybe four of us could get this done in 3 months, no C++ required.

Ixnay on bugtrackers. I'm not going to learn 30 different bugtrackers,
when they consistently ask the wrong questions and aren't responded to

I don't use bugtrackers. They're all different, requiring learning
each one, they ask the wrong questions, and in most cases bugtrackers
are where problems go to die.

On April 10 2022 I took an hour or so creating CSS that reproduced LyX'
standard of not indenting the first paragraph after a heading, and
posted it on the list, asking that somebody forward it to the
developer's list. I posted the complete CSS. I solved the problem and
all I got for my trouble was criticism. Screw it.

Yeahh, this is one of the reasons I don't use LyX for ePub. Last
time I looked, LyX exports used the deprecated and now with HTML5
eliminated  inside a div specially made to contain
one . What could *possibly* go wrong?

If I had to eliminate these redundant  things, I'd do it
with a postprocessor that corrects LyX' complexifications. It's not
easy, but you can use Python with the "import xml.etree.ElementTree as
ET" library. You'd analyze every DOM element, and for every 
whose only purpose is to encase one , get rid of the div after
reading metadata from that  and any  silliness, applying
the information to attributes of the  itself.

Seriously, LyX has failed to export common sense XMLized HTML for 14
years now, and I doubt they ever will. Best you can hope for is to
either switch to another authoring program, or repair LyX' mistakes
post-export. I think trying to repair this stuff from within your LyX
document is walking the highway to heartache.

Also, the good thing about the XML-parsing Python post-processor
approach is that, as time goes on, you can fix any problems newly
discovered and/or newly added by LyX: You're in control as long as they
continue to export well-formed XML HTML, which of course isn't a
for-sure thing.

You're speaking my language tush!

It's been years since I looked at any kind of LyX HTML export, but if
it's what you're saying now, I might revisit the situation.

I think what you're asking for is best handled by a post-processor that
modifies the exported well-formed XML HTML5. Easy and fast with a
Python program that:

* Replaces existing doctype with 

* Gets rid of that silly  line.
  HTML specs say that the UTF-8 line belongs in the ". Like you said, the language line
  belongs in  or whatever language you want.

* Replaces the exporter's CSS stylesheet with your own. I don't think
  you want to mess with your LyX styles in your layout file because you
  WANT your PDF styles to look very different from your HTML styles.

This is all accomplished with a very easy to write Python program that
will postprocess the exported file in a half a second. If the exported
file is *really* well formed XML, you can check it with my
xmlchecker.py shown at
http://troubleshooters.com/web/validating.htm#xmlchecker .

That can't be right. Python 2 has been deprecated for years. I'm sure
LyX gives you the choice to use Python 3.

Hi Joe,

If for some reason the answers you've received don't fit your needs,
please remember you can always put special text tokens in your LyX
file, then run a Python3 program of your own device to make necessary
insertions, changes and deletions to produce what you want.

For instance, in your text you could have a vvvQUESTIONSvvv and a
^^^QUESTIONS^^^ bookend your questions, and a >>>CORRECT<<< at the
beginning of each correct answer. The Python program would remove the
tokens after reading them, and put the answer section where it belongs,
with the correct answer(s) having a different character style.

I did this in the past, and it worked. Obviously an all-LyX solution is
better, but one nice thing about LyX is its native format is still
reasonably parsable so if nothing else works, writing such a program is
always a way to get what you need. Basically, it just adds one more
short step to the compile process.

First, if the forms will be OCR'ed, you'd better have the right font
and spacing. Otherwise, it's pretty easy...

Your layout file defines environments and commands. Commands are the
basis of character styles, and can be used for other things too.

So invent a stylename (environment or command) for each appearance you
see on whatever form you're imitating, and then do a little trial and
error with the styles until yours looks exactly like the sample.

I haven't discussed the nuts and bolts of custom layout grammar. If you
need that, give me back a shout.

Re: License Agreement Entitlement Query

[Steve Litt]

I wouldn't suggest replying to these guys. They're trying to put the LyX

think the GPL2 is clear enough for me to stake my business on, but if
they have questions, they can hire a lawyer.

Or, if they don't like the project not acting as their lawyer, they can
start using a proprietary substitute, and REALLY start paying lawyers.

Like I said, I spent an hour getting that code just right. I did the

could have forwarded my email. 

I don't have time to learn the quirks of every project's bugtracker,
type in information that's not relevant, and hope somebody looks at it.
At a lot of projects, the bugtracker is where requests go to die
(Bluefish, you listening?).

If I could change one thing about FOSS it would be to get rid of
bugtrackers and work directly with the user. That's what we did at
VimOutliner, and bugs got solved and requests got implemented very
quickly.

Making first paragraphs not indented in exported HTML

[Steve Litt via lyx-users]

Hi all,

In the past, some exporters have implemented the custom of not
indenting the first of several successive paragraphs by using a
different class of paragraph for the first of a series of paragraphs.
This way of doing things makes more work for the person writing the
export, and more work for the person converting the export to
acceptable ePub, because those special classes will need to be backed
out or otherwise specially handled.

Not indenting the first of a series of paragraphs is easily
accomplished by the following two lines of CSS:

p::first-letter{margin-left: 3em;}
:not(p) + p::first-letter{margin-left:0.0001em;} 

Let CSS decide which is the first of several consecutive paragraphs,
and let CSS define what to do with that paragraph. Make it easy on
everybody.

I took an hour to figure this out. Could somebody please take 3 minutes
to forward it to the developer's list and also the person who is
writing the HTML export?

Thanks,

I'm on tons and tons of FOSS mailing lists. From my perspective, the
LyX list is one of the most welcoming to users new and old, and has one
of the most constructive attitudes of all mailing lists. In my
opinion, this list is so welcoming that there's little remaining low
hanging fruit remaining to make the list even more welcoming, so I
still think enabling non-subscribers to post is unnecessary and has
downsides.


If we want to grow LyX usage and membership, and I'm not necessarily
saying we should, I think the way to do it is to grow the world's
impression of LyX beyond its perceived niche of scholarly thesis
production. As long as we speak only of PDF output, LyX is
spectacularly suitable for any consistent document beyond five a4 or
letter pages. When used with its defaults, *IT'S JUST EASY*. With
creative custom layouts, it can do almost anything. One of my fiction
books, which jumps all around in time, has the current date of the plot
printed in the header. Don't try this with Libreoffice.

Somebody could make a list of all types of possible long documents.
Legal documents. Books, articles. Specifications. Make a flowchart of
which document class to start out with.

Like every other free software project, LyX is underdocumented. The
lowest hanging fruit you have is to make a single index for all the
documents available under LyX' help menu. Every time I go there to look
something up, I spend 25 minutes going from document to document
looking for the subject. I'm sure I'm not alone. Armed with this index,
the project could credibly claim to have some of the FOSS world's best
documentation. Make the documentation good enough, and newbies will
quickly become evangelists. But wait: There's more...

I never learned to use LyX modules, and have always simply made complex
and detailed local layout files. Others should not follow in my
footsteps, because, from what I've heard, modules are a much easier way
to add specific document capabilities than layout files. There should
be a help=>modules, split into descriptions of how to use every
project-curated module, and how to make your own.

I can see value in a publicity campaign, beamed to the general populace
rather than current LyX users, explaining what fingerpainting is, why
it's bad, why styles-based authoring is good, what styles-based
authoring looks like in general, and how easy it is to do in LyX.

In this section I've merely scratched the surface of ways LyX could
become an everyday tool for millions of people. Just doing a few of
these things would go beyond making LyX welcoming --- they'd make LyX
extremely attractive for the general population.

I'd suggest you put it back the way it was. I'm on 30+ FOSS mailing
lists, and can't police everything to see that it goes through. If some
AI algorithm somewhere decides I'm spam because of my email provider
or whatever, I'm just writing into the wind, wasting a lot of time.

The following simple Python3 program checks to make sure the file that

Or, the LyX project could fulfill their goal of making LyX' native
format an XML dialect, and then any developer could convert a LyX doc
to any other format quite easily.

The trouble is, in the early 00's, the LyX project decided to make the
LyX native format an XML dialect, which greatly increased the
difficulty of parsing a LyX file, but did not carry through in making
LyX files well formed XML. If they'd carried through with making it
XML, converting it to anything else would be relatively simple. As of
now, it's the worst of both worlds: Difficult parsing because of some
XMLisms, but not parsable by an XML parser because it's not well formed
XML.

One more thing. In my opinion LyX' HTML export suffers not from
technical deficiencies, but from deficiencies of specification. Please,
don't do us the "favor" of adding appearances to the HTML. Instead,
just pass the styles through as-is, and let people like Ken Kopelson
and me handle conversion of style to appearance, which is done simply
with CSS. When you pass appearances instead of styles into the HTML,
you're doing extra work, and sabotaging us.

And please make the output well-formed XML as well as HTML5. HTML5 can,
but doesn't have to be, well formed XML. It's a couple orders of
magnitude easier to deal with if the exported HTML has all opening tags
accompanied by closing tags, and for tags that both open and close
( for instance), be sure to put the trailing slash.

Also, please either give the output file an XML DTD/schema that defines
HTML characters like  , or else just output their numeric
equivalents, eg.  . Ken Kopelson, do you agree with this
paragraph?

If you want to go the extra mile in making things easier for people
writing LyXHTML to ePub converters, a nice but by no means necessary
favor you could do us is to output a CSS file listing all the styles in
the document, and perhaps giving some best-guess appearances for each.
Or else make them all big and red, so the self-published author can
easily specify each later on. But please, please, PLEASE, do not throw
in an all-possible-styles CSS file that bloats up our books and is
extremely difficult to deal with. I'd rather personally write an XML
parser that looks at the XHTML5 file and outputs the CSS.

All previous attempts have considered the exported HTML to be the final
file for reading. This is clearly false: It's an intermediate file, and
as such, should be very easy to parse (do the slight extra work to make
it well-formed XML), and pass ONLY styles into it, no appearances.

And this thing where standard paragraph environment translated to two
different , one for the first line and one for all the rest so that
the first line isn't indented, please don't. This is easily done in CSS,
and even if it weren't, we converter makers could easily write a
converter program to change it to two different , AT THE VERY LAST
PASS before outputting the file intended for the reader.

And please, don't throw in all sorts of extraneous  elements like
previous attempts have done. If fifteen consecutive paragraphs are in
the, let's say for example, "story" environment, just begin each
paragraph of the output with  instead of putting them
all in a . I've seen past LyXHTML go several levels
deep in unnecessary  elements. Life shouldn't be that difficult.

Once again, all past attempts at LyXHTML have unnecessarily bitten off
way more than they could chew. Just pass us the styles, and we'll take
care of the style to appearance translation, *at the right time*!

Not in LyX, from the command prompt. It will tell you which child

LyX is great software by a great project. Great projects can be very bad
in certain respects, and that doesn't prevent them from being great
projects. As you read my response to your question, please keep in mind
that I'm very grateful to LyX for being the tool that created at least
8 of the books I currently offer. My responses merely point out how
LyX could be much better in the area of exports. Here are, my answers
are enumerated below.

1) The converter must be semantic. It must keep styles as styles til
   the very end, not prematurely convert to appearance. The LyX native
   format is hostile to that goal, and since 2007 the LyX devs have
   shown little interest in that goal.

2) File conversion software has no business being written in C++ plus
   Qt. Python, Lua, Ruby, Perl or *maybe* simple C are the right way to
   go, at least for version 1. If performance became a problem, and I
   doubt it would, it could be rewritten in C. Years ago I stopped
   using both C++ and Java because, in my opinion, they both suck.

3) Simplicity is an asset. Conceptually all that need be done is create
   Xhtml5 tags with the same names as the environments and insets. But
   that's not what I've seen from the LyX (X)HTML exports in the past
   decade. Simplicity is an asset: The conversion software should be
   separate and distinct from LyX, with a very thin interface.

  3.1: Content in semantic Xhtml5 can be converted to anything.

4) If I had time to help the LyX devs, I'd have time to singlehandedly
   create a Markdown=>Xhtml=>ePub and Markdown=>Xhtml=>PlainTeX=>PDF
   software stack. The QOwnNotes software is already a great typing
   front end for Markdown, which is why I chose Markdown. With the
   Markdown based converter done, I could turn around and easily create
   an Asciidoc version.

5) I could have, offered to, and would have written the converter for
   the LyX project, if only they had followed through with their mid
   00's plan of making LyX an XML dialect. They refused to do so.

Bottom line, in my opinion, the LyX project is the wrong project to
build the LyX to ePub (or to (X)HTML) converter. Alex Fernandez was
right about that when he built eLyXer, and IMHO eLyXer was better than
the native LyX converter at that time, but eLyXer was only half
semantic.

If the LyX project can export to some completely semantic XML, I'll be
glad to join the team who does the conversion from there.

Tragically, you've just uncovered the main problem. As long as LyX is
considered a front end to *LaTeX*, there will never be a good, robust
LyX=>ePub. Only when LyX is considered a front end to *everything*
will semantic ePub, as well as conversions to formats we haven't yet
dreamed of, be possible.

If it's DocBook *xml* as opposed to sgml, and if the DocBook XML is
merely a representation of the environments and insets of LyX, that's a
perfect point of demarkation between LyX and (HTML | ePub | other).
You'd probably use Pandoc for DocBook=>ePub, I'd probably write my own,
but either way, it could work if DocBook *XML* and styles are kept as
styles.

Re: EPUB converter

[Steve Litt via lyx-users]

Hi Ken,

I suggest you put it out. The LyX project has a 15 year history of
outputting pidgeon HTML incapable of building a *semantic* ePub,
claiming what they've done is good enough, and treating with hostility
my observations that they're prematurely converting style to appearance.

The LyX project is the wrong project to do LyX=>ePub; ePub isn't in
their DNA, and until I'm shown otherwise, I'm treating any LyX=>ePub
capabilities from the LyX project as vaporware.

Where can I download your converter with instructions?

Thanks,

SteveT

I wish I'd known about -userdir 21 years ago when I started using LyX.
Thanks for telling me now.
