There was indeed a conflict between two python distributions installed in my 
system: the distribution from Fedora and Intel python.  This is also related 
to my other thread (Support for xfig graphics).
I removed the intel distribution and now it seems that everything is working 
as it should.

Thank you.

It seems that the problem was indeed a mix-up with different python 
distributions.
Got rid of the Intel python distribution and now the internal conversion of 
Xfig files is working again.

Support for xfig graphics

2022-06-21 Thread Rudi Gaelzer
Running:
Fedora Core 36 on x64 box
KDE Plasma Version: 5.24.5
LyX Version 2.3.6.1 (provided by Fedora repo)

It seems that the support for xfig figures is not working on my system.  See 
the 
attached files.
The Xfig file sets the TeX flag for text.

In the LyX window, the preview fails.  When I try to view the document with 
pdflatex, the following error message appears in the latex log:

! LaTeX Error: File `0_home_rudi_temp_ufrgs_Coulomb_Law.pdftex_t' not found.

Exporting to LaTeX (pdflatex) generates the attached file.  Running on terminal:
rudi@stix|ufrgs>pdflatex tes_xfig01.tex
gives the expected error:
! LaTeX Error: File `Coulomb_Law.pdftex_t' not found.
because the exporter did not generate the Coulomb_Law.pdftex_t file.

That worked.  First, I copied the original .lyx to 
-lyxformat-508.lyx, then ran 
$>/usr/share/lyx/lyx2lyx/lyx2lyx -lyxformat-508.lyx -o .lyx

That successfully converted the original to format 544, which the frontend was 
able to render.
Is it possible that there's a bug in the automagic process?
I'm running the installation from the rpm packages distributed for Fedora core 
35/36.

I thought about doing something similar, but not exactly as you suggested. 
With the totcount package, you register the counters you'll want to keep track 
of with the 
command 
\regtotcounter[auxfile=first.tc]{thm}
It will create the counter thm@totc and set it to zero.  At the end of the run, 
the counter is 
written into first.tc.  I need to inform this file name to the next lecture.
So, inside the InPreamble, I registered all theorem counters.
Two problems resulted:
1. I got a lot of "!Missing number, treated as zero" errors.  
2. If I ignore the errors and finish the processing, the total counters of the 
environs that 
are NOT used in the document are written in first.tc, all set to zero, as 
expected.  
The problem is that the counters that ARE used are again incremented every time 
the file 
is processed until all cross-references are right.
This time, I inserted the \setcounter{defn}{\totvalue{defn}}
command in the *.inc file.

> For the second issue, can you wrap your preamble code in AtBeginDocument{}

That seems to work.  Thanks for pointing out the command.
So, I inserted 
\regtotcounter[auxfile=\currfilebase.tc]{thm}, etc
in the  appropriate places in the *.inc file.  The command \currfilebase comes 
from the 
currfile package.  It just contains the base file name, without the extension.
And then, if I know that in the next lecture the Definition and Exercise 
environs are used, 
inserting in the InPreamble

\AtBeginDocument{\setcounter{defn}{\totvalue{defn}} 
\setcounter{xca}{\totvalue{xca}} }

does the trick.  The counters are set after all the rest of the preamble is 
processed.

Thank you.

Incidentally, in order to create locally the *.aux and *.tc files needed for 
cross-referencing, 
I have to first export the document to LaTeX and then manually run 
pdflatex --draftmode 

Is there a way to instruct Lyx to write certain auxiliary files into the local 
directory, instead 
of in /tmp/lyx_tmpdirxxx?

Problems related to custom AMS theorem module

2021-07-23 Thread Rudi Gaelzer
This question is still related to the recent thread:
https://www.mail-archive.com/lyx-users@lists.lyx.org/msg112228.html[1]


I thought I got it right, but several unexpected problems came up and I'd like 
to have your 
opinion.


What I want to do is the following: I'm preparing a series of lectures that 
will employ 
theorem-like environments.
Several lectures are related to the same subject and so I want the enumeration 
of 
numbered things (equations, figures, theorems, examples, definitions, etc) in 
subsequent 
lectures to continue from the previous ones.


In order to guarantee the correct sequence, I'm loading in the preamble the 
totcount 
package.  For each counter employed in a given lecture, the totcount package  
creates a 
new counter (equation@totc, figure@totc, etc), which contains the last value of 
the 
counter.  
The values of these counters are then written in a specific file (call it 
previous.tc), which 
can be read in the subsequent lecture.  Finally, by using 
\setcounter{}{}
I can guarantee the desired continuation of the enumeration of things.


For the native LaTeX counters (equation, figure, etc), I've been including all 
the necessary 
commands in an ERT with the layout InPreamble.
For the native counters, this works all right because the counters are defined 
with the 
class and class packages, which are read before user-specific definitions 
incuded with the 
InPreamble layout.


However, for the theorem-like environments, the implementation is more 
involved.  The 
problems that are coming up are:


1. Say a given environment like theorem is only introduced from the second 
lecture.  In 
this case, the file previous.tc will not contain the last value of the counter 
thm@totc, 
because there was no theorem in the first lecture.  Hence, I cannot issue a 
\setcounter{thm}{} because in this case the number of the first 
theorem gets 
increased for each LyX/LaTeX compilation.
This complicates the implementation of the custom theorem-bytpe module I've 
been 
tinkering with in my previous thread.  Somehow I need to introduce instructions 
to read 
the previous.tc file and find out if the counter thm was previously employed.  
Only if there 
is a last value of thm@totc that I can \setvalue the counter.  
I'm not sure what will be the best way to implement this.  Several posts I've 
been browsing 
through suggest the use of TeX natives like \newread, \openin \read, etc, and 
then use 
some package (like xstring) that identifies specific strings in each line read. 
 Seems too 
much trouble for me.


2. Then I decided to dumb down my approach.  I will only use \setvalue for 
those counters 
that I know are employed in the previous lecture, as I was doing so far with 
the native 
LaTeX counters.
The problem now is that with the layout InPreamble, those instructions will be 
written 
before the ams-theorem module defines the thm counters.  That is going to give 
errors.
It seems that as of now there is no way to choose the ordering of the 
instructions 
contained in the layout InPreamble inside the document's preamble.  This is 
discussed in 
this thread:
https://www.mail-archive.com/lyx-users@lists.lyx.org/msg100172.html[2]


Therefore, the only solution that I can imagine is to write the necessary 
instructions in the 
user-defined preamble accessible in 
Document Settings -> LaTeX Preamble
This way, I guarantee the correct ordering of the instructions.


Anyway, I just wanted to vent out my frustration that I was not smart enough to 
somehow 
automatize this process.  This is an admittedly very specific problem, and I 
don't know if 
you think this can be of interest to the larger community.

Since I want something quite specific, I created the new environment with the

Re: Customizing counters of theorem environments.

2021-07-21 Thread Rudi Gaelzer
I would like to run by you my solution and ask another question.

I copied the files theorems-ams-bytype.module and theorems-ams-bytype.inc into 
my 
local layouts directory (with new names), then edited them accordingly.  For 
instance, in 
the .inc file, for the Lemma style, inside the Preamble EndPreamble field I 
included the line 
  \renewcommand{\thelem}{\thearea-\arabic{lem}}
\thearea being the prefix to the lemma counter.

Did similar things for the other styles, then reconfigured LyX and voila! My 
customized 
module is accessible (and works as intended).
I just don't know if this solution is sanctioned by you LyX developers...

Now the question I want to ask.
I want to create a new theorem-like environment.  Reading through the 
Customization.lyx 
manual, I understand that the different translations for the names of the 
environs reside 
in the layouttranslations file.  Looking into it, it says that

# This file has been automatically generated by po/lyx_pot.py.
# PLEASE MODIFY ONLY THE LAGUAGES HAVING NO .po FILE! If you want to regenerate
# this file from the translations, run `make ../lib/layouttranslations' in po.
# Python polib library is needed for building the output file.

I confess I did not quite grasp the process. Do I have to create a local 
layouttranslations 
file containing the translations for the new environment name?  Is there a more 
detailed 
guide for this procedure?

Well, it seems that the solution is indeed via \renewtheorem.  However, I had 
to dig deep 
into the installation of AMS theorem to find the proper names of the counters.
So far, I've found \thethm, \thelem, \thedefn, etc.
I did not find a full list of counters, so if someone could point me out where 
I can find such 
a list, I'd be grateful.

Customizing counters of theorem environments.

2021-07-20 Thread Rudi Gaelzer
Hi there.
I'm using the module Theorems (AMS, Numbered by Type).
I would like to change the counters of theorem-like environs, adding a fixed 
string in front 
of the number.  Something like 

Theorem TGA-1
Definition TGA-2
etc

Can I do that the usual way that is done for the standard LaTeX counters?
I mean, in ERT: 
\renewcommand{\theequation}{TGA-\arabic{equation}} 
I that case, I would need to know the names of the counters, but I can't find 
them.

Or is there another way?
Thanks.

Instant preview: different sizes in different situations

2021-03-11 Thread Rudi Gaelzer
Using:
LyX v. 2.3.6.1
OS: Fedora Core 33
TeXLive v. 9

I noticed a weird behaviour for some time already with Instant Preview.
In: Preferences -> Look & Feel -> Display -> Instant preview, 
if I set Preview size 1.2, then during the edition, when a given formula is 
rendered for the first time, the display size is OK.
However, when I restart LyX and resume processing the text, the same formula 
is rendered with a much smaller size... very difficult to read.

If I try to circumvent this problem by setting preview size to, say,  1.5, 
then on the first time the equation becomes huge, although after restart the 
new size is better than with the previous setting.

Has anyone noticed this behaviour as well?  I'd say this is a bug, but, I 
don't know...

Indeed.  It works separately for "[" and for "]".
It also works separately for "[" and for ")", which is not a bad thing per se.

About my idea of browsing through the variable-sized delimiters, should I put 
it

Worked.
Interesting development.  I usually employ variable-sized delimiters, but often 
need to use \big, \Big, ...

Another development that would be handy would be the possibility to browse 
through matched delimiters
   ( ),  [ ],  { },  | |,  ... 
or to change them hierarchically using shortcuts.
This way it would be much easier to work with nested expressions.

LyX + Beamer: continuing previous counters

2020-08-05 Thread Rudi Gaelzer
A question for TeXperts and LyXperts alike.

In these times of coronavirus pandemic, all my teaching materiel is in the 
process 
of being moved to cloud-based venues.  
I'm using LyX/Beamer to prepare my lectures in presentation form, and in the 
course of preparing a number of subsequent lectures, I came across a problem 
related to cross-references that I wish to solve in an automatic way.

Say I prepare a given lecture as a Beamer presentation and number some 
equations/figures/etc for future reference.
I'm using the xr package to reference labels created in other presentations, 
but I 
also want to continue the counters in subsequent lectures.
The problem now poses as the following.  How can I automatically continue the 
counters in the next presentation?

Should I include the different presentations as children of a master LyX file?
I did not try this possibility because I fear it would mess up the individual 
tables 
of contents.

Is there any LaTeX command/package that provides the last value of a counter in 
a 
file, so that I can use it in another tex file?

Indeed.  
I reconfigured LyX with the new configure.py, but then when I loaded the 
Embedded Objects guide it complained about a couple of new modules that are 
not present in 2.3.4.  Moreover, although the rendering no longer complained 
about inkscape, other processing errors ensued, probably due to the missing 
modules.

Anyway, thanks for the tip.  I guess I'll just wait for v. 2.3.5...

Conversion error for Help files

2020-06-03 Thread Rudi Gaelzer
Suddenly, an error is occurring whenever I try to render any one of the Help 
files (User Guide, Embedded Objects, etc) into PDF.
The error is related to conversion of images using inkscape.

This is the first error message:

An error occurred while running:
inkscape --file="2_usr_share_lyx_images_dialog-show-new-inset_graphics.svgz" 
--export-area-drawing --without-gui --export-
pdf="2_usr_share_lyx_images_dialog-show-new-inset_graphics.pdf"

Lots of similar error messages occur and I have to kill the process.

Any idea on what could be generating this error?

Dear Paul.
I just installed you module in LyX as per instructed. Thank you for your
contribution.

I may have some questions about it as I'm testing it.
A first question is: does your module support the \algstore and \algrestore
commands?  I have some algorithms that I'd like to break through different
pages.

If I go to the main page (www.lyx.org) and click Bug Tracker, it opens the
LyX Bug Tracker
page in https://www.lyx.org/trac/wiki/BugTrackerHome
I believe that's the correct place to report bugs, right?
I will have to register first, in this case.

Another detail came up.  I did a simple test with a document containing 3 
short chapters. 

>From the GUI, in Settings -> Child Documents -> Master Document Output -> 
Include only selected children  I can select only some child documents and 
then create the PDF in File -> Export -> PDF (pdflatex).  The exported PDF

However, if I export from command line with

the PDF will invariably contain the whole document.
I can sen the test files if you wish.

lyx --export pdf2 master.lyx

Now, if I want to export only some of the childs to PDF, is there a
standard way to accomplish this?
The only other relevant instruction in the FAQ is related to branches:

lyx -x "command-sequence branch-activate b1; branch-deactivate b2" -E pdf2

As I understand, you are creating the document with Asciidoctor before
converting it to HTML (or ePub), correct?

Thank you for the suggestion, but I would rather stick to LyX/LaTeX for
document creation.

Another feature I would like added to LyXHTML is the possibility to split
the
hypertext in different levels (e.g., chapters) instead of creating a single
large file (order of  MBs).

Configuration of LyXHTML

2019-08-10 Thread Rudi Gaelzer
I have just tested LyXHTML with a complex document (lots of childs, cross-
references, listings, etc) and found that the result is fairly good.
However, all the files that were generated were stored in the same directory 
as the sources.
Is there a way to configure LyXHTML to change the following:
1. Write the files in another directory.
2. Color of the items in TOC.  They are black by default.  Can I change the 
color?
3. Using the "Fancy Colored Boxes" module.  I inserted a Custom Color Box in 
the master document and the configuration of said custom box was rendered at 
the top of the xhtlm page.  That configuration should not have been printed.
4. Also using the "Custom Header/Footerlines" module.  The field titles: "Left 
Header:", "Right Footer:", etc, were also included in the xhtml.  They should 
be invisible.

Any tips?

It does after I made a slight correction.  Notice that in your file the
overlays are actually outside the overlayarea.  You can see it clearly if
you export to LaTeX.

I you then include the onlyenvs inside the overlayarea (see attached), then
the result conforms what I was expecting. The difference between the two
cases is that in the first case, the baseline of the permanent text is
moved upwards as more lines are added to the frame, whereas in the second
case (all onlyenvs inside the overlayarea) the baseline is fixed.  This is
what I wanted.



Thanks for the tip.  I did not try with overlayarea because I was not sure
about the overlay height.  But it seems that setting a total height of 0cm
does the trick.

Beamer help: nested overprints

2019-04-03 Thread Rudi Gaelzer
I have a problem with Beamer that certainly has a very simple solution, but
I'm not able to find it...

In the attached file, there is a single frame.  The first line appears on
all subframes, but the following lines are inside a main overprint
environment.  The second line should appear only on the second slide, the
third line on the third and fourth slides and it should replace the second
line. There is also a fourth line that is overprinted on the third and
fourth lines.

However, the second line does not appear on the PDF, only the remaining
subframes.  My use of a nested overprint inside a parent overprint is wrong?

Thank you.

Superscripts in ABNT keyboard: version 2.3.1

2018-10-15 Thread Rudi Gaelzer
Ever since LyX was upgraded to v. 2.3.1 the rendering of math superscripts
changed.
Using a ABNT (brazilian) keyboard map, which provides accents (acute,
grave, circumflex, cedilla, etc) as dead keys, up to the previous version
(2.3.0), whenever I wanted a superscript in math mode I would use the
circumflex accent key.  That would have the same effect as the key-binding
Alt+M E, both in LyX math mode and in LaTeX.
Now, since v. 2.3.1 was installed, if I want to renderize $a^2$, for
instance, in LyX math, it will display literally a^2.  After exiting math
mode and with instant preview active, the LaTeX rendition will display the
correct format.

Subscripts are still rendered either with Alt+M X  or with "_"
(underscore), as it was always done.

This is not something terribly annoying, but with an ABNT keyboard it is
much faster to employ the single "^" key than pressing the 3 keys Alt + M +
E.

It's not quite like that.  If I run bibtex for each child individually, the 
bbl's are generated 
without a hitch.  The error comes when I bibtex'ed the main file.
Your bibtexall script does not distinguish between the master and children

processes them all, without issuing any message to the console.  Where is the

System: Fedora Linux 24
LyX version: 2.2.2

So, I followed the instructions here: 
https://wiki.lyx.org/BibTeX/Tips#secbib
in order to use chapterbib with LyX.
1) The script bibtexall was downloaded, chmod'ed as executable, and put in a 
directory cited by PATH
2) Went to Tools -> Preferences... -> Output -> LaTeX.  In Bibliography 
Generation: Processor: Custom - Command: bibtexall
3) Created a simple master-child structure (1 master + 2 children).
4) In the master's preamble: \usepackage{chapterbib}
5) Each child file has its own bibliography.

When I process the master with pdflatex, the following BibTeX error message 
appears: 
==
This is BibTeX, Version 0.99d (TeX Live 2016/dev)
Capacity: max_strings=35307, hash_size=35307, hash_prime=30011

A level-1 auxiliary file: 2_home_rudi_temp_lyx_chapbib_c01.aux

3_home_rudi_temp_lyx_chapbib_c02.aux

I'm skipping whatever remains of this command

==

I did not commit any error, LaTeXwise speaking. When I exported everything to 
pdflatex, the following sequence:

pdflatex main
bibtexall
pdflatex main
pdflatex main

produced the expected and correct PDF file.
Below, I'm attaching the files (*.lyx, *.tex, *.bib)
Any ideas?

Re: Rolling lists in Beamer

2016-12-07 Thread Rudi Gaelzer
I see.  Anyhoo, it's good to learn about all possibilities.
Thanks again.

Since we're talking about beamer and you seem a proficient user, another tweak 
I've been struggling to implement is a better control on the positioning of 
objects such as figures or boxes that will remain fixed at a given position 
whereas the remaining of the slide wraps around it.

I've obtained a partial success with the wrap figure float, which call the 
wrapfig pack, but I don't really have a total control on the positioning 
(since it's a "float" after all) and the outcome is less than satisfactory.

Some people report success using the cutwin package, others recommend pgf-tkiz 
for figures and/or textpos for boxes.  I still haven't come around finding 
time to test all possibilities, though. Do you have any suggestion on this 
regard?

Re: Rolling lists in Beamer

2016-12-07 Thread Rudi Gaelzer
Hi Jürgen.
Thank you for your reply.
Your improved rolling list solution is what I was looking for.  I was trying 
to implement the same result using Edit -> Text Style -> Only, but in this 
case the result is different. 

Your "clever" rolling list solution is the implementation of the other 
suggestion from the site.  That one I was able to implement exactly as you 
did.

What I was really interested in were rolling lists that contain nested lists 
with items that themselves are supposed to appear only in certain slides.
I was able to implement that result inserting the "only@" clause in the item 
overlay specification for those particular nested items.  See the attached 
file with my tweaks.

The "clever" implementation is IMHO the most elegant solution, but there are 
some subtle differences in the rolling behavior.  The most evident is that 
with the "clever" rolling list, one has to continue changing slides until the 
only item remaining is the last.  Do you know if there's some "cleverer" way 
to avoid that?

Anyway, thanks again.
As I learn new things about the beamer class the more impressed I become with 
its flexibility.

Rolling lists in Beamer

2016-12-07 Thread Rudi Gaelzer
Has anyone implemented with Lyx-Beamer any of the "rolling lists" discussed 
here(?):
http://tex.stackexchange.com/questions/69609/rolling-bullet-points-in-beamer

I can implement the first example, but with heavy ERTing (see attached).
I'm just wondering if anyone has a more elegant implementation...

I did not compile, just used the binaries released by the updates repo of F23.

LyX 2.2.0-1 on FC23: some math shortcuts not working.

2016-06-11 Thread Rudi Gaelzer
I've just installed on my desktop the 2.2.0-1 version delivered by Fedora 23 
updates repo.
The overall layout is much prettier and I'm eager to test the professed 
support for retina displays when I upgrade LyX on my laptop.

However, I have refrained from installing the upgrade on the laptop because 
when I tested the 2.2.0 version with the desktop I've found out that some 
useful mathematical keyboard shortcuts were no longer working.

For instance: "ALT+M F" did not entered the \frac command; instead it just 
will open the dialog window for math spaces.  "ALT+M (", "ALT+M [" and 
"ALT+M {", instead of creating the respective math delimiters would simply do 
nothing.  Also, exponent generation with the caret "^" works sporadically.

There may be other shortcut problems that I have not detected yet.  Anyway, 
those I mentioned are annoying, because the shortcuts significantly speed-up 
the typing of mathematical expressions.

Have you noticed something similar, or can this be a specific Fedora issue?

I've been doing exactly the same thing, but a tad different.
After the .aux file is generated, I run it through the bibtool app:

$> bibtool -x yourfile.aux -o yourfile.bib

that should generate your tailored bibtex database.
After that, you'll only have to change the \bibliography{...} command inside 
yourfile.tex to
\bibliography{yourfile}

That's been working for me.

Change tracking: no change bar in PDF output

2015-12-31 Thread Rudi Gaelzer
There is a possible bug here:
Using change tracking with PDF output (pdflatex), the \lyxdeleted and \lyxadded 
commands work as supposed (respectively: read, strike out and blue).  However, 
the change bar is not printed at the margin.

Looking at the source, I noticed that LyX uses the xcolor, pdfcolmk and ulem 
pacs to show the changes, when the output is directly piped to a PDF.

OTOH, if I export the doc to (plain) latex, LyX will use the dvipost package.  
Then, with "pplatex " and "dvipdf ", the resulting PDF contains the 
change bar.

Here is the source text, which won't printout the change bar.

Hi, Phillip.  Thanks for replying.

Nope. I'm running LyX 2.1.4.  In Insert -> Custom insets there are only:
"Float link", "lowercase" and "Surname".
That was the first place I looked at...

RevTeX 4.1: \onlinecite

2015-10-13 Thread Rudi Gaelzer
I'm writing a MS using revtex class, V. 4.1.
How do I insert specific commands for the RevTeX class 4.1, such as 
\onlinecite?

I've found this post:
https://www.mail-archive.com/lyx-cvs@lists.lyx.org/msg09818.html
claiming that revtex4-1.layout supports \onlinecite.

Thanks.

Enumitem and multiple columns modules: bad mojo.

2015-05-29 Thread Rudi Gaelzer
I've seen a lot of reports in this list about the interaction of the enumited 
module with other latex classes (such as powerdot) or other modules, most of 
them regarding the Enumerate-Resume option.

Well, now I add my own.  I elaborate several exercise lists for my classes.  
Usually, the problems are printed in 2 columns, but eventually I need to 
switch to single column for a while and then resume the 2 columns.
Enumerate-Resume only works with the sequence 
1 column -- 2 columns
With the reverse (2 columns -- 1 column), the counter is always reset.  See 
the 2 first attached examples.

According to the tests I performed, the counter will only follow the correct 
sequence if I use the series= and resume= options.  However, if I blindly 
enter the Enumerate Option (with Alt+A 1) inside an Multiple Columns inset, an 
error message about a missing number will occur.  Exporting the text to latex, 
I noticed that the reason is because the enumitem option will be copied as a 
\begin{multicols} option (see mul_col_enumited3-lyx_output.tex).

The only workaround I found was entering manually the number of columns before 
(re)starting the list.  The attached mul_col_enumitem7.lyx file is the version 
that works as it should.

Perhaps there's a bug in any of the modules?

Re: Opening beamer with Lyx 2.1

2014-09-04 Thread Rudi Gaelzer
I'm facing the same problem with a beamer presentation created with LyX 2.0 
(\lyxformat 413).
Now, I have version 2.1.1 but I get the same crash message.

 There are some known issues with Beamer conversion, which we hope are 
 solved for 2.1.1. If you want, you can download the lyx2lyx files from 
 git.lyx.org and replace the existing ones, or just compile the 2.1.x 
 branch for yourself. Failing that, 2.1.1 should be out in about two weeks.

Re: Unsupported math environments

2014-06-27 Thread Rudi Gaelzer
Dear Jacob.
Thanks for the reply.
However, I think that the solution suggested by Guy Rutenberg will only work 
for math COMMANDS.  See the attached file, where I define a math macro \pFq in 
order to write the symbol for generalized hypergeometric functions.

What I want and need is a means to implement the math ENVIRONMENTS defined by 
the mathtools package and that are not explicitly supported by LyX.
Specifically for multiline equations.  LyX supports the standard AMS inner and 
outer environments, such as align (outer) and aligned (inner).  However, 
multline is only an outer env in the standard AMSmath.  The mathtools pack 
defines the corresponding inner multlined environment, and it seems that there 
is no way to use it other than ERTing the math input (see attached file).
I guess the same tweak can be applied in order to use the other new 
environments defined by mathtools, such as dcases, rcases, drcases, 
psmallmatrix, bsmallmatrix, etc.

The only other alternative I was able to find was this suggestion by Uwe Stôhr:
http://marc.info/?l=lyx-usersm=117565214529188w=2
which would demand some tweaking with the default spaces of the multline 
environment (see file).

I also tried to create first a tex file with

\[
 \begin{multlined}
  a = \\
  b
 \end{multlined}
\]

and then import it into LyX, but only the first line was used.  So, I guess 
multlined is indeed unsupported.

Dashed lines in array/matrix environment.

2014-04-22 Thread Rudi Gaelzer
The embedded objects manual teaches us that by using the arydshln package
one can create tables with horizontal/vertical dashed lines.

However, I want to do the same in the math environment.  I need to
represent matrices in block-diagonal notation and the use of dashed lines
is one way to distinguish the different parent matrices.

In math mode I can create horizontal dashes within a pmatrix inserting
\hdashline before the first element of a given line in order to put the
dash over it.  However, for the vertical dashes, I had to resort to ERT:
==
(within the ERT):
\[
\left(\begin{array}{c:c}
a  b \\
\hdashline c  d
\end{array}\right)
\]
==
Notice the {c:c} that puts the vert dash between the columns.

It works but it's not wysiwyg... is there no other way to do this within
LyX?
Thanks.

Re: Rendering of LyX's math screen fonts.

 Rudi Gaelzer wrote:
 
  So I ask you LyXperts: is it possible to configure the math mode editor so
  that it uses also mathabx and other different math fonts?  The roadmap to
  LyX 2.1 mentions enhanced support for math font selection (OpenType fonts)
  and support ofr cropped PDF/EPS.  However, AFAIU, these enhancements will
  have an effect on IP and on the exported document.  Seems to me that the
  math editor will still use the same screen fonts.  Or am I wrong?
 
 You are right, the mentioned features do not affect the look of the math 
 editor. However, there are some new symbols in 2.1, mainly from stmaryrd.sty 
 and mathtools.sty. To some extent you can also add some on your own: The 
 screen appearance of math symbols is defined in the file lib/symbols, which 
 contains some very basic documentation for 2.1.
 Basically, there are three kinds of symbol definitions in that file:
 
 1) symbols supported by special insets (like the decorations)
 2) symbols supported by fonts (like the ones from fontmath.ltx)
 3) symbols without any builtin support
 
 Adding symbols of type 1) and 2) requires some programming in LyX, and 2) 
 requires also a true type font containing the symbols in a certain order, 
 but symbols of type 3) can easily be added by users: All lines starting with 
 \def are of this kind. For example, you could define \partialslash like 
 this:
 
 \def\partialslash{\partial\kern-12mu/}
 
 The slash is a bit too short, but maybe there is a longer one already 
 supported by mathed, which you could use instead. Although this looks like a 
 TeX macro definition, it is not used for the output, only for display in 
 LyX. There is basically no documentation how exactly this \def works, you 
 have to use trial and error. You could also make the mathabx package load 
 automatically if this symbol is used (works only for packages in the 
 compiled in feature list of LyX, and mathabx is in there):
 
 \def\partialslash{\partial\kern-12mu/} mathabx
 
 I strongly advise against doing so, because this makes your LyX document 
 depend on your personal installation, and it would not typeset on vanilla 
 installations. This feature is rather for symbols distributed with the 
 official symbols file.
 
 Finally, if you want some symbols to appear officially in LyX, you could add 
 them to bug , but please note that font changing packages like txfonts 
 will not be used.

Thanks a lot for the tips.  I'll try them out as soon as I have some time.

 
 
 Georg
 
 
 PS: It is funny that you also use the math editor for calculations. I used

I only tried them out for very simple cases as well.
Begging the pardon of LyX's developers, you'll find this resource much more 
developed in texmacs, if you're not aware of it:
http://www.texmacs.org/tmweb/home/welcome.en.html
There, you'll find interfaces for several different CAS, such as those you 
mentioned.

 You are right, the mentioned features do not affect the look of the math 
 editor. However, there are some new symbols in 2.1, mainly from stmaryrd.sty 
 and mathtools.sty. To some extent you can also add some on your own: The 
 screen appearance of math symbols is defined in the file lib/symbols, which 
 contains some very basic documentation for 2.1.
 Basically, there are three kinds of symbol definitions in that file:
 
 1) symbols supported by special insets (like the decorations)
 2) symbols supported by fonts (like the ones from fontmath.ltx)
 3) symbols without any builtin support
 
 Adding symbols of type 1) and 2) requires some programming in LyX, and 2) 
 requires also a true type font containing the symbols in a certain order, 
 but symbols of type 3) can easily be added by users: All lines starting with 
 \def are of this kind. For example, you could define \partialslash like 
 this:
 
 \def\partialslash{\partial\kern-12mu/}
 
 The slash is a bit too short, but maybe there is a longer one already 
 supported by mathed, which you could use instead. Although this looks like a 
 TeX macro definition, it is not used for the output, only for display in 
 LyX. There is basically no documentation how exactly this \def works, you 
 have to use trial and error. You could also make the mathabx package load 
 automatically if this symbol is used (works only for packages in the 
 compiled in feature list of LyX, and mathabx is in there):
 
 \def\partialslash{\partial\kern-12mu/} mathabx
 
 I strongly advise against doing so, because this makes your LyX document 
 depend on your personal installation, and it would not typeset on vanilla 
 installations. This feature is rather for symbols distributed with the 
 official symbols file.
 
 Finally, if you want some symbols to appear officially in LyX, you could add 
 them to bug , but please note that font changing packages like txfonts 
 will not be used.

Thanks a lot for the tips.  I'll try them out as soon as I have some time.

Rendering of LyX's math screen fonts.

2013-11-07 Thread Rudi Gaelzer
This is a recurrent problem for me, and I think it's for other as well.

Certainly someone has already discussed this issue in this list (or in the 
devel list), but every time I take some time to browse through them, I cannot 
find it, or perhaps I'm not sufficiently knowledgeable on the internal working 
of LyX to really identify the subject...

Anyway, whenever I'm editing a mathematical equation and have a need for a 
symbol not included in the standard latex and AMStex sets, I have to look for 
it elsewhere. 

A good place to look for new symbols is the 'The Comprehensive LaTeX Symbol 
List'
http://mirror.ctan.org/info/symbols/comprehensive/symbols-a4.pdf
So, if I want the \partialslash symbol, I have to edit the preamble and 
insert \usepackage{mathabx}.  If I want the double square bracket delimiters 
\ldbrack and \rdbrack, I have to \usepackage{txfonts}, and so forth. 
It works fine to generate the exported document in PDF or PS and also with 
Instant Preview.  However, the math equation editor (or math mode) does not 
render non-AMS/latex symbols, but leaves them as ERT's.

That's ok if you are creating a document with LyX, but for those of us that use 
LyX to make mathematical calculations as well, the rendition of all symbols 
goes a long way to facilitate the visualization of the mathematical expression.

So I ask you LyXperts: is it possible to configure the math mode editor so that 
it uses also mathabx and other different math fonts?  The roadmap to LyX 2.1 
mentions enhanced support for math font selection (OpenType fonts) and support 
ofr cropped PDF/EPS.  However, AFAIU, these enhancements will have an effect on 
IP and on the exported document.  Seems to me that the math editor will still

Re: Forward/reverse search and LuaTeX

For me, Forward/Reverse search only works with pdflatex.
For Xelatex I probably should enter with some custom configuration.  If anyone 
knows how to do it, please advise.

Even with pdflatex, reverse search works ok, but for Forward search the 
--unique specification is not obeyed.  Every time I want the jump LyX = PDF, 
a new instance of Okular is launched.

 Automatic setting fails with LuaTeX (for me, at least).
 
 I got reverse search (from pdf to lyx) working by following the manual

 format (pdf6: Luatex/Synctex) and changing the compilation instruction to:
 
 lualatex -synctex=1 $$i
 
 Regular LuaTeX compilation would otherwise fail with an Undefined control
 sequence error on the /synctex line in the preamble.
 
 But I cannot get the forward search (lyx--pdf) working properly. When I
 select Forward search from the pop-up dialog I always get a new okular
 instance. The Okular command in Tools-Preferences-Output-General is
 
 okular --unique $$o#src:$$n $$f
 
 
 Apparently, the unique flag is ignored.

Cross-reference to subeq. within subequations environ

2013-09-04 Thread Rudi Gaelzer
Ok, I know I should've first read the whole AMSmath documentation before asking 
this but... this is faster...

Say I have a bunch of equations within a labeled subequations environment.  
Something like (in LaTeX):

...
\begin{subequations}
\label{eq:eq1}
\begin{equation}
Some math
\end{equation}
Some text
\begin{align}
Some math \\
Some math \\
Some math
\end{align}
\end{subequations}
... \ref{eq:eq1} ...

The equations are all labeled with the same number and with the roman 
subnumbers from a through d.
As long as I'm aware, I can only \ref{} the main label.  I can not make an 
automatic reference to a particular subequation unless I label it as well.
If I don't do it, I have to write the roman subnumber manually.  However, if I 
later on insert another equation within the subequations, I'll have to scan the 
whole document and fix the subnumbers in all cross references...

Does anyone know of a way to automatize this process?  Without having to label 
individual eqs, I mean.  Perhaps there's a package in CTAN that I don't know 
of.  And does LyX support it?

Thanks.

... \ref{eq:eq1} ...

The equations are all labeled with the same number and with the roman 
subnumbers from a through d.
As long as I'm aware, I can only \ref{} the main label.  I can not make an 
automatic reference to a particular subequation unless I label it as well.
If I don't do it, I have to write the roman subnumber manually.  However, if I 
later on insert another equation within the subequations, I'll have to scan the 
whole document and fix the subnumbers in all cross references...

Does anyone know of a way to automatize this process?  Without having to label 
individual eqs, I mean.  Perhaps there's a package in CTAN that I don't know 
of.  And does LyX support it?

Thanks.

Re: Display of Inkscape svg images not working.

2013-05-02 Thread Rudi Gaelzer
Hi, Scott and Paul.
Thanks for the suggestion.  Running lyx on debug mode provided some 
information.  See the dbg file attached. I deleted my ~/.lyx/preferences file, 
reconfigured lyx, closed and opened it again, as usual.  Got the same problem...
I was puzzled because I could not find any error message in any file created in 
the ./tmp/lyx_tmpdir. directories.

What I'm trying to do here is the following: I have a JPEG image which I want 
to edit somehow.  I'm doing this with xfig, Ipe and Inkscape, all of which can 
apply layers over the original image that contain the modifications I want to 
make.  So far, the only vector graphics app that works well with Instant 
Preview is Ipe.

With Inkscape, I initially imported the JPEG figure using the link option, 
which simply creates a link (duh!) to the original JPEG image.  In the debug 
test I'm sending attached, I created a newfile1.lyx text where I first inserted 
the original JPEG and then the Inkscape (*.svg) image.  Instant preview worked 
well with the jpeg, but I got the same blank square for the svg.  It seems that 
lyx was not able to follow the symbolic link contained in the svg file to the 
jpeg image.  Take a look at the last lines of the dbg.

After this test I decided to create another Inkscape svg file, where I inserted 
the jpeg with the embed option.  This time, I was able to view the image on 
lyx.  I guess this is why Ipe works, since it always embed the imported images 
into its *.ipe files...

Anyway, I hope this is useful somehow.
Thanks again.
