Changing the zoom level forces a redrawing of previews. I've made a 
shortcut for


command-sequence buffer-zoom-in; buffer-zoom-out

which leaves the zoom level as it was but forces a document-wide 
redrawing of previews.

You need to add \usepackage[utf8]{inputenc} to the latex preamble so that
LyX will
know what is the correct encoding.

Attached is a .tex file that  I successfully imported to LyX (I think), the
text is taken
from here <https://zh.wikipedia.org/wiki/%E6%98%A5%E7%AF%80>.

See the following for encoding info of the original TeX file which is
being imported into LyX:

werner@X10DAi:~$ encguess test.tex
test.texUTF-8
werner@X10DAi:~$ uchardet test.tex
UTF-8
werner@X10DAi:~$ file -i test.tex

I don't know what do you mean by saying this. I just do the import via
File->Import->LaTeX (Plain).

Instead of copy a LaTeX code try to import it via
File->Import->LaTeX (Plain).
Then the equations should appear in a new LyX file,
and you can copy them from there.

If I understand your question, you should open the following menu:

Tools --> Preferences. Then in the window Lyx: Prefrences you have to 
open the menu: Look & Feel --> Display.

Hello,

Hello,

This functionality does not exist yet, but indeed it would be doable 
(either pasting, or transforming an expression in place).


I would like to be able to use a command to copy and paste the LaTeX 
code for the equation /as it is formatted/, so that any traces of the 
macros in the source code are removed in doing so.  I use LyX all the 
time for my mathematical typesetting work and I have found macros to be 
extremely useful, but the downside of this is that the equations cannot 
be pasted into other software without some way of defining the macros or 
creating preambles in those packages. The other software packages I have 
in mind are ones that have a plugin to support LaTeX but aren’t designed 
with it in mind (e.g. GeoGebra, Blender, InkScape etc.).


Are there any plans to implement such a feature (and how much would it 
cost to implement such a feature if not)?


There are no current plans for that, that I know of. Indeed, paying 
someone to do it may help to materialize it sooner. I suggest that you 
create a ticket on www.lyx.org/trac. I will forward it to the developers 
list to try to find someone willing to implement it.

For an example of what I mean, I have a piece of documentation in LyX where
the code is given by 

 

0=\dfrac{\partial^{2}\inTheSolid{\dimensionless A}}{\partial\dimensionless
x^{2}}+\dfrac{\partial^{2}\inTheSolid{\dimensionless
A}}{\partial\dimensionless y^{2}}

 

where inTheSolid and dimensionless are both macros (which themselves depend
on other macros) created so that the text looks like this:

Please see attached for how I use vphantom—it's not pretty in LyX, but it
works well in the final PDF.

with a new document, containing two copies of your example. The first
copy is pasted into an ERT box (so that I can see what you are
shooting
for). The second has most of your example, but not the nested
brackets,
typed into a multiline math environment. The first line of the
multiline
formula is selected, so that I can put a left bracket in front of it.

The second screenshot shows the delimiter insertion dialog. Note
that I
unchecked the "keep matched" box below the left pane, then selected a
left bracket in the left pane and "(None)" in the right pane.

The third screenshot shows the formula after I click "Insert" in the
delimiter dialog. There is a large left bracket at the start of the
first line and "phantom" bracked (dotted line) at the end of the
first
line. To insert other brackets, do similar things, selecting the
content
of the bracketed area and where appropriate selecting none on the
left
and a closing bracket on the right.


Paul,

Thanks for picking up the thread!  If you provide the LyX file for 
shot3, I’ll demonstrate what I meant about vphantom.


Thanks again,

Thanks for the reply.  I can't see how to do this.  Inserting
Delimiters seems to insist on inserting a pair of delimiters - I don't
see any way to just get \left[ for example.

To accomplish this, I prefer to use the Insert Delimiters capability (the
subject of an adjacent thread).  Using "none" will let you give the
appearance of matched delimiters that vertically scale to contain the
contents.  The "Swap & Reverse" button is meant as a convenience to control
delimiter insertion in this manner.  Finally, if you have lines that vary
in vertical extent, a vertical phantom (\vphantom) with the proper contents
will ensure consistent delimiter sizes.

Hope this helps,

Large delimiters, multiline equations

2021-01-22 Thread Neal Becker

I have an equation that has to be split (to fit into beamer
presentation).  It has large delimiters that span the lines.  Does lyx
have any facility to help with this?  I did get a useable result, but
only with a lot of ERT.  Lyx seems not helpful here, is there any way
other than ERT to get "\Biggl. ... \Biggr]"?  Or "\right."?

Here is what I wanted:

\begin{multline*}

\mathbf{X}_{N_{C}\times S\times
A}=\left[\left[\left[\sum_{n}m1_{p+cL_{c}+nS}m2_{p+cL_{c}+(n+\tau)S}^{*}\right.\right.\right.,\\

The breqn package seems like a noble if not perfect effort. Someone

how to put the bits of ERT before and after the equation to get it set

worthwhile to put an example on the wiki.
It couldn't hurt, particularly if the example showed how to break within

causing things to look even worse, even though I added two “aligned” lines to the
referenced code block. (If you look at the code you’ll see the obvious places to add

How do LyX-ers handle this? Is there “LyX” solution to breaking long equations?
I’m OK with some ad hoc solution for now, or some ERT if it works.

line break, \\, in the LaTeX output). If that doesn't achieve what you want,
perhaps you could post a minimal example and a specification of what the output
should look like.

Paul

Thanks, Paul. I’m on a Mac so of course Control-Enter has no meaning. Usually this
translates to Mac-speak as Command-Enter. When I do Command-Enter in my equation,
which is unfortunately inside a align environment, it instead adds a row to the
matrix that represents the align environment. Ditto for Shift-Command-Enter. These
two commands in LyX are mapped as Insert -> Formatting -> Ragged Line Break and
Justified Line Break, respectively but invoking the menu commands with the cursor in
my equation has exactly the same effect: adding a row to the align matrix (above the
row where the cursor is.) When (Shift-)Command-Enter is done to a non-align display
equation a similar thing happens except now the non-align equation is converted to an
align equation with a blank new row _below_ the original equation.

Right now I guess I would be pretty happy with merely a way to make
Command-shift (Control-shift) do what is expected which is apparently break the
equation instead of creating a new row.

Jerry

Jerry,

I just created an align environment with two equations, the left side of the
first being ridiculously long. When I put the cursor somewhere toward the
middle of the left side of the long equation and inserted a break (using
Ctrl-Enter -- I'll get to the Mac part in a minute), it broke the equation and
inserted a new row. So

(x+x+x+x+...+x) =1
y =2

(where the right column contained the equal signs and integers) became

(x+x+x+...
+x+x+x+x) =1
y =2

where the right column is empty in the first row. See the attached minimal
example. Is this not what you want?

Regarding the key mapping, if you can find an unused key combo that you have a chance of
remembering, you can map it to "newline-insert newline" using Tools > Preferences...

Paul,

I’ve attached an example showing a few things, mainly that
Command-(Control-)-Enter works with your equation and the equation from Section
18 of the Math manual but not with my equation.

Jerry

Jerry,

As explained in my reply to your prior message, the breaking in the
wrong place issue is apparently caused by the use of balanced [] around
the chubby part of the formula.

Regarding the rest, I also get a bunch of (apparently harmless) LaTeX
errors/warnings when I compile it. As to why the version you liked
failed to be transferable to its intended destination, I have no idea
about that. Although I have the breqn package installed, I have never
used it, so I don't know with what other packages (or standard LaTeX
things) it might be incompatible. The change I made in the previous file
also works here, and (since it is vanilla LaTeX and does not use the
dmath environment) should be portable.

Paul:

Thanks. The effect appears to work by adding another row to the matrix and
filling it with the partial equation. In your example the new row is on top. If
the long equation is moved to the RHS the new row is below.

I tried adding horizontal space to the second line of your broken equation but
Latex seems to ignore it: when I click outside the math box and the equation is
rendered, it is rendered without the horizontal space even though it was
visible while in math editing mode.

About Mac key mappings: According to the status line in the document window,
when I hit Command-Shift, it displays “(newline-insert newline;) and then icons
for “Command” and “new line” which is an arrow thingy. So I’m going to assume
that the key mapping is correct but that there is another problem, meaning…

…See my attached example. Attempting to break the line before the second
exponential (1) doesn’t break the line, (2) adds a matrix row above, and (3)
steals the = from the now-third row and puts it on the second row.

The failure to break with Command-Enter does not seem to be a function of t

One thing I've been known to do is to put in a lot of intermediate
steps, so each equation is short.

How to break long equations with LyX

2020-06-19 Thread list_email

I have tried mightily to get LyX to break long equations. I’ve studied multiple 
pages at stackexchange, both LaTeX and LyX, and can’t seem to get anything to 
work.

I have had luck in the past with the second large block of code at this page:

https://stackoverflow.com/questions/2904807/lyx-breaking-long-formula-lines

but today I have some problems with it.

First, it doesn’t work if the \text command appears inside my own LaTeX code 
that appears between \begin{dmath} and \end{dmath} or if I try to use the trick 
twice in the same document. (That’s a tentative analysis of the problem.) 
Specifically, LyX runs at 100% CPU eventually gives me a chance to abort and 
then follows up with this additional message: "The external program pdflatex 
finished with an error. It is recommended you fix the cause of the external 
program's error (check the logs)."

Plus, I now want to to apply the line breaking to a line within an aligned 
environment (Insert -> Math -> Aligned Environment in the menu system.) This is 
causing things to look even worse, even though I added two “aligned” lines to 
the referenced code block. (If you look at the code you’ll see the obvious 
places to add the lines.)

How do LyX-ers handle this? Is there “LyX” solution to breaking long equations? 
I’m OK with some ad hoc solution for now, or some ERT if it works.

I've never used the breqn package, but with ordinary and AMS math

break it (inserting a line break, \\, in the LaTeX output). If that
doesn't achieve what you want, perhaps you could post a minimal example

Jerry,

I regret that I don't have any good guidance to satisfy your desire to
automatically break equations.  One benefit to LaTeX is the aesthetic as a
result of the underlying algorithms, but I know of no automatic algorithms
to universally break equations well.  I suspect this is the case because
each component in the equation has distinct meaning and how the equation is
broken and aligned can help the reader interpret it (e.g., breaking at
"logical" places).

As such, the two approaches I take are to either use multiline or aligned
equations (with the "right-hand side" indented with a manual \quad).  This
has produced equations I'm usually happy with.  Multiline is a bit more
"automatic," but it can produce equations that aren't totally satisfying
(e.g., 6b in this paper
<https://www.osti.gov/biblio/1542798-monte-carlo-importance-splitting-analytic-benchmark>
).

Sorry I can't offer a good and direct answer, but I hope these thoughts
help.

Equations - Preview Issue

2019-01-01 Thread Baris Erkus

Hello,

I am using Istanbul Tech. Univ thesis class. Attached are the MWEs, the 
layout file and the ITU thesis class file.

Some equations are not previewed and there is no apparent reason. All 
other equations are previewed nicely.

I have tried the article class, which works fine. So I believe it is 
related to ITU thesis class file. Still it is funny only one or two 
equations are not previewed.

Did anybody experienced similar issue with other classes?

Thanks and happy 2019 to all...

Test, whether this "ø" in your source is really
00F8LATIN SMALL LETTER O WITH STROKE
or some other similar looking symbol which may be missing in the text font
used for the instant preview.

You don't have to close LyX if you save under a new file name or? At 
least I don't have to in order to see the effect.

I don't know. But since this behaviour seems like a bug, I'll forward it 
to the developers. Here is a short summary:


Steps to reproduce:
1. Open the attached file.
2. Set Preview to "On".

Actual result:
- The ø is omitted in the preview but not in the output.

Expected result:
- It is not omitted in both

Thanks. I think I have narrowed down the problem to "Default output set to "

Can you confirm that the problem goes away if you use the "Default" 
output format? (To force LyX to regenerate the preview you can just save the

With \text{}, space is automatically handled. With \mathrm{}, I need to use the

There is a problem with \text{} if I use Instant preview *on*...: if I include character

The generated PDF file *includes* the symbol "ø", but ... it does not show up

Presumably, this is a problem with other non-English ASCII characters, too?

I cannot reproduce the problem. The ø in the attached file shows with instant

This is on Windows 10 Pro 64bit version 17134.345. ("latest version"

recently pulled "October 2018 Update".)

Here is my "template_test.lyx" file, which contains displayed math with \text{} 
containing letter "ø". This letter is not displayed wieh I have enabled 
"instant preview". It does show up when preview in LyX is turned off. In any 
way, it shows up in the generated PDF file.

Still, it annoys me that it doesn't show up when I turn on "instant preview".

Any clues? I use the latest version of Windows 10 (v 1803) 64 bit, LyX 2.3.1 64

Hm... I opened a new document of the template, and in this new template, the 
preview works. But it does not work in another document from the same template, 
where I'm in the process of inserting text from an OCR scanned paper copy of a 
document I wrote 30 years ago... (using Adobe Acrobat for OCR).

This is weird. Maybe some junk from the imported, scanned document? I'll test 
some more.

Hi David, it appears that this is a limitation of ulem.sty (which is
inherited by LyX's track changes feature). See:
http://www.lyx.org/trac/ticket/9678

I've checked with ulem's author and he said he would consider extending
the support for display math (it appears to be a tricky issue). I just
pinged him again (now a year later), so we'll see what he says.

As for the short run, I don't know of a workaround.

Best,

Lyx Change tracking show changes in output not working with displayed equations

2016-05-30 Thread David Halpern

Hi,

I would like to print a hardcopy changes in output (deleted and added).
If what I deleted does not contain a displayed equation, I can export the
contents of my lyx file to a pdf file, and then print it out. However, if I
delete a displayed equation, then an error message appears during the
export to a pdf phase. I've also exported a lyx file to a plain latex file,
with the changes in output on. In this case, again I get similar errors.
With the changes in output off, latex does not generate errors.
Is this a limitation of "tracking changes" or an error?
Let me know how to get around this problem.
Thanks.

Hi everybody there,

I'm  writing maths with Lyx and I know how to change the color of a
equation by first highlighting it and then rightclicking and choosing and
then picking text style in the menu that pops up, and then personal style.
But what I would like to do now y to change the colour or a part of the
equation to highlight the part I want the reader to look at. When I
highlight the part and rightclick on it, the menu doesn't pop up. I have
search in the forum but I didn't find any solution. Can anybody give me a
hand? Thanks in advance. Manuel.

By the way, I'm writing slides using the one of the Beamer styles. And I'm
using standard 2.1.5 release for Windows 7. Just in case this piece of info
is relevant.

I agree that selecting stuff in a formula can be quite tricky.
However, there is one important reason speaking against more padding:

If you press the space bar inside mathed, this has the effect of an
"escape"¹ but it does *not* insert whitespace. This is easily overlooked
already with the current display, adding a padding makes it even harder
to detect if the formula is followed by whitespace or directly by text. 

(There are use-cases for both: "$x$-axis" or a formula followed by
punctuation as well as formulas in the middle of a sentence requiring
whitespace around.)

¹ Leave the current box (in the main box you leave the formula).

Note that our padding is AFAIK done in absolute pixel size. Using a

padding at edges of equations

2015-09-20 Thread Jack Sankey

Hello!

Is there any way to change the padding (i.e. the number of pixels) on the
sides of equations?

The reason I ask is when I'm trying to select part of an equation I often
need single-pixel mouse precision to avoid grabbing everything. Adding a
pixel or two of buffer on the edge would be pretty helpful. This is also
true for things like "the stuff inside a square root" though adding pixels
there might make things ugly..

An added (read: not important) bonus to adding a few pixels on the sides
would be the equations look nicer when the background doesn't match that of
the page.

Cheers,
Jack
