Hi, after upgrading to 2.1.4, all math is now displayed with the "elbow"

Here is the display I expected:

But the attached is what I see (on the same UserGuide.lyx document). As
you can see every bit of math has the four markers around it, which is
distracting.

Is this configurable somehow?

You may want to try pdflatex instead of luatex, or if you need luatex

If you are willing to try LyX, I would recommend testing Change tracking

Is a list of math macros very different from a list of ERT insets?
Will both contain cryptic code?


Every math-macro has a unique name (as it defines a macro which is later
used by this name), while an ERT inset can contain arbitrary
LaTeX code, usually just calling already defined macros.


Right. So this is about a collection of macro names. Same approach
would be useful with Sweave/knitr chunks, using their labels (and
numbering, especially when labels are missing) in the Outliner.

Yes if we implement lists of custom insets then it would be easy to make 
an inset argument behave like a caption from the outliner point of view

As Lyx provides more user-friend space to write the science, I would

File/Import/latex(plain), but the error occurred while running. As I am
very new in Lyx, I could not understand the information given here
. Please let me know there
is any simple way to do so.

Best regards,
Nader Mahmoudi



Dear Nader,


After having looked at the files it seems that creating a dedicated 
layout is the only option. The class ozu-thesis.cls is based on the 
report class so we can start from there. See the attached file 
ozu-thesis.layout which would be your starting point and which just 
loads the layout for the report class.


To use it you need to create a lyx file and select a local format file 
under "Class". See the attached example lyx file which needs to be saved 
in the same directory as ozu-thesis.layout, ozu-thesis.cls and the other 
files.


At this point it only has the features from the report class. You can 
then extend it with the features from ozu-thesis.cls in two ways:


* Use ERT to directly input LaTeX commands (this is quickly cumbersome 
for environments that you are going to use often but will allow you to 
move forward).


* You can progressively define the missing environments in the "Local 
format" pane after reading the "Customization" guide and the many 
examples located in the "layouts" dir of your lyx installation.


Try to compare the "view source" pane with the example tex file if you 
encounter problems.


Hopefully, once you are done, you can send us the final state of your 
layout so that others will benefit from your work.



Best,
Guillaume

IBus incompatibility

[Guillaume Munch]

There is currently a serious incompatibility between LyX and IBus (the
default input method in Ubuntu and Fedora) that causes various problems:

 * The keyboard starts outputting the wrong keys

 * LyX completely and definitely stops responding

 * When using arrow keys or page up/down, the movement continues for a
long while after the key has been released.

If you have experienced these bugs and use Linux, then you may be a
victim of this incompatibility. The main trigger is a heavy system load
so it happen more often to users with long documents with which LyX is slow.

I have just found the reason to these bugs so I wanted to share the
workarounds:

 * Disable IBus just for LyX (if you don't need a special input method):
   Run LyX with the command line:
 XMODIFIERS= lyx
   or equivalently (in Ubuntu) adapt /usr/share/applications/lyx.desktop
   as follows:
 Exec=env XMODIFIERS= lyx %F

or:

 * Set IBus to synchronous system-wide (keeps IBus in LyX, but does not
   solve the third issue and causes problems with the hangul input
   method):
   Add the following line to .xsessionrc (create if needed):
 export IBUS_ENABLE_SYNC_MODE=1

[-- Type: text/plain, Encoding:  --]



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..


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.)




A better solution would be to only need to go over half the inset to 
select it, as suggested in http://www.lyx.org/trac/ticket/9748

I do like the idea of a PassOptionToPackage tag.

Some options like \zoomfactor even want to be output before the document

Then, in any equation you want to flag, just type \mytag in the equation

you leave the LyX portion of the macro empty, LyX will expand the macro

Test 2

When using LyX, the fact that you have generated or not a blank line
is basically hidden. As far as I know, the only way to detect it is
looking at the LateX Source panel.
Hence my question is: Is there a workaround to know where I placed a
blank line?
Is it possible that Lyx shows a special character, or something
similar, to let you know where you put a blank line (I mean something
like the carriage return in WORD, that can be visible or it can be
hidden)?

Currently I have installed Ubuntu 16.04 LTS - and am facing a very strange
an annoying problem: I have difficulties to select longer or even shortes
pieces of text with the keyboard or mouse.

If I am trying to select some text, the selection captures only short
passages and fails after some words or paragraphs, regardless of whether I
am selecting with the mouse or with keyboard shortcuts. ALl other programmes
(text editor, Libre Office etc.) are working correctly and I can select text
withput any problems.

I am facing this problem with at least 4 computers, all of them have
installed Ubuntu 16.04 LTS and LyX 2.1.4. I am running another machine with
Debian 8.x and have no problems at all. Of course I have tried different
keyboards and mice, I have also reinstalled Lyx and TexLive and I have
deleted my old Lyx configuration files.

I would very much appreciate all hints and tips to solve this problem.

Why should they be better than Ctrl-A or Shift-end?

I really think that the shifted and non shifted functions should
coincide.



To clarify what I mean: Mario's idea is suitable for flat formulae,
whereas the current behaviour is more suitable for formulae with lots of
nested insets in the shape of trees. Ctrl+A is not enough for moving and
selecting in the latter. But you have a point with shift+end providing
the same functionality as shift+ctrl+right, I had never tried it.

Hi Mario,

What I have not been able to understand is which function I should bind
to ctrl+right so that this combination drives me from A to B or from C
to D instead of from everywhere to E


I agree ctrl+arrows could do better. The attached patch implements your
suggestion.

Pro: I find this behaviour more useful. It could be made better by
skipping strings of characters that constitute "words", but I am not
sure how to define this notion properly in mathed. (Jean-Marc speaks of
using the rel/bin/op categories to find a criterion, let's think about it.)

Con: it is a bit unintuitive that ctrl+arrow behaves differently from
ctrl+shift+arrows. But I believe that the current behaviour of
ctrl+shift+arrows is fine and should be kept.



Incidentally, I also do not like very much the fact that if in A then
shift+right selects all the A-B portion of the formula: in my view, this
should be the behavior of
ctrl+shift+right, whereas shift+right should select only the very next
character (that is, the numerator if I am in A).


Selections in LyX correspond to meaningful objects, not portions of
LaTeX code such as \frac{1} in your example. So what you propose for
shift+right does not make sense to LyX.

As for ctrl+shift+arrows, I find them useful to select entire insets
quickly.

Movement:
   left/right arrow move one character (where entering or exiting an inset,
such as going into/out of a subscript, counts as a "character" for movement
purposes);
   ctrl-left/right jumps the adjacent "grouping", where "grouping" is the
subtree at the current node if we were to diagram the math inset as a tree;
   home/end jumps to the start or end of the entire inset;
   ctrl-home/end jumps to the start or end of the buffer (document).

Selection: shift+any navigation combination selects everything from the
current cursor position to where the unshifted key combination would take you.


As I wrote, this is not entirely possible.



I don't know if Guillaume's patch would fix this or not. Right now, there do
not seem to be any LyX functions (LFUNs) that relate to this notion of a
"grouping" or syntactic tree node.


My patch assigns the behaviour you describe for ctrl+arrows to word-* 
movement lfuns.



Internally (meaning in the C++ code),
something like that seems to exist from what Jean-Marc wrote.


Jean-Marc suggested to skip bigger chunks delimited by their category 
(reation, operator...). This would make sense for both ctrl+arrows and 
ctrl+shift+arrows. This does not exist yet and we can give it a try once 
Jean-Marc commits his patch that defines these categories, which I 
encourage him to do.

Yes, something would have to be done about this: a combo box, or an

insets, not specific to beamer-flex.





There is an enhancement request for this sort of thing: a combo box,
like for layouts, that could be put on the toolbars.


But still, you would need to
1. put the cursor outside the inset
2. use the mouse to enter a new frame

whereas currently, starting a new frame from within a frame is a one-
keystroke action.


I agree. I was imagining a new lfun that splits a text inset into two,
at the location of the cursor, similar to the current environment-split
for environments. One use is to create a new inset after the current
one.



Also, these flex insets cannot be reordered by the outliner, and
reordering frames is a crucial function at least for me.


I am not worried about this one. One advantage of flex insets is that
they are easier to select as a whole and also in sequence, making
copy-paste an appropriate tool. (In contrast, the outliner does not let
us move several frames at once.)



IMHO the flex idea sounds neat in theory, but in practice has too many
shortcomings (which all, arguably, can be solved).



I think the new lfun is the only one to be really urgent.

Although I can find a workaround, but I am frustrated due to complex

It does not work if the cursor is at the separator. But it works if you 
place the cursor at the end of the last list item and press Alt+P Shift 
Enter.


Another way to introduce a separator is usually to press Enter enough 
times, but the Frame's KeepEmpty property interferes with it.

I've started a similar approach (based on experience with my

Here's beamer-flex.layout, beamer-flex.module and an example document
(the original conference template).

The goal is to replace the various Frame, Block and Columns styles with
corresponding flex insets all the while inheriting the original layout
for all the rest. These are now found in Insert > Custom insets. I have
already used it successfully to prepare a few talks and found that flex
insets let me focus on the contents.

In addition, the module can be used on top of the original beamer.layout
to have both methods at the same time, for instance for converting a
beamer presentation into the new layout.

I have additional tweaks such as making the frame title automatically
match the subsection title, but I did not include it in the attached.

I am interested in any feedback that you may have.

Have you accidentally  encrypted this files? If so, I doubt someone is able to

This are definitely no text files.




To add to Kornel's questions, have you checked the "compressed" option
in the document menu for these files recently? The files would look end
up looking like this (but your files are not recognised as compressed
files here).

What is your operating system? An infection by a ransomware is not to be

Thanks a lot.


The goal is to replace the various Frame, Block and Columns styles with

for all the rest. These are now found in Insert > Custom insets. I have
already used it successfully to prepare a few talks and found that flex
insets let me focus on the contents.



In addition, the module can be used on top of the original beamer.layout
to have both methods at the same time, for instance for converting a
beamer presentation into the new layout.


I simply kept the old Styles in beamer-flex - however your approach is
cleaner for creating new documents.


Yes, I also wanted not to clog the interface, and with the module it is
easy to have both.



There is an years-old feature request to allow auto-converting of Style to
FlexInset via an ObsoletedBy keyword.
It was, however deemed too exotic as this might easier be implemented via a
lyx2lyx routine. (However, the latter cannot be used with a local install
without changing lyx versions :-(


I am sceptical about the lyx2lyx approach because you have to join
adjacent paragraphs. It would seem easier to deal
with with an ObsoletedBy tag to me. But being able to convert
automatically is not that important I find.

If the template comes with a custom class file, then you need a custom

Hi Bernt!

I replied to the general list because I think that your message will
meet a wider audience there.

Le 06/07/2016 13:39, Bernt Lie a écrit :

Hi LyX!

I have a question on the LyX user interface, then some
wishes/questions. (I used FrameMaker 1989-1991, LaTeX/emacs
1992-1994, and Scientific WorkPlace 1994-now.)

*Question*: I use Windows 10 on a Dell XPS 13 inch laptop (owned by
employer). I also own a MS Surface Pro 4 privately.

·Both the Dell and the Surface Pro are **high resolution** laptops.

·The menus/icons in LyX are so small that they are **almost**
unreadable.

·Is there a way to switch to a “large icon/text” mode for the user
interface?


LyX 2.2 on Windows is compatible with Hi-DPI screens. To change the size
of icons you can do that from the contextual menu of the tool bars
(right click).



*Question/Wishes*: I like your (partial) support for /literal
programming/. I used Mathematica ca. 1990-1992, and Maple 1992-2000 –
these have some Notebook features. I have also used Scientific
WorkPlace (first Maple, and then MuPad from 1994-now). I also used
Framemaker 1989-1991, which had some built-in symbolic computation
support. Nowadays, there is more interest in “Freeware” in academia.

·I’m moving into Python etc. + Jupyter (Jupyter notebooks support a
large number of languages, starting with Julia, Python and R, and
expanding).

·Any chance of LyX to allow **import** of Jupyter notebooks? Here,
I’m referring to “static” import?

·Any chance of LyX supporting **live** Jupyter notebooks?


No clue about this one.



*Questions/Wishes:* One of the things I really liked with
FrameMaker, was a good built-in /drawing tool/, which allowed me to
insert math into drawings. The drawing tools were not fancy, but
coverend what I needed. Today, I use MS Visio. I essentially use the
same features as in FrameMaker Draw, but with the addition of Layers.
I make physics/engineering type drawings, e.g. velocity profiles in
pipes, tanks with liquid levels, mixers, etc.


I highly recommend Inkscape with the textext plugin. I hope it is
available on Windows. Textext lets you write latex into your drawing.
Then LyX lets you incorporate the resulting svg and converts it into pdf
flawlessly.


*Final comments*: I tested LyX some 10 years ago, but switched back
to SWP due to its efficient math editor. Some things I hope work
better in LyX are:



(i) smooth scrolling of math, figures, tables,


What do you meant with this?


(ii) easier use of specialized classes/styles for conferences and
journals,


Possible, but still painful depending on how far the class is from a
standard one.


(iii) better support of color, minipages, etc,


LyX has that, but I do not know how it compares. But also, the custom
layout mechanism would let you define your own style and insets, so it
is possible to invest into LyX and adapt it to your own way of doing things.


(iv) better support of program listing, large tables, insertion of
pdf files from other sources, etc.


LyX has all that.

Guillaume

No, it is not. It is possible we will see in in the 2.2.x series.


Robert,

Be careful what you wish for. Even if/when LyX finally has ePub
export, the question is "what quality ePub?" Will it be like the HTML
and Xhtml exports, having all sorts of extraneous CSS styles to do
silly stuff, deprecated stuff like , and the like?
Just because something outputs something they call ePub, and it's
decipherable by Calibre's ebook-viewer,  doesn't make it the kind of
ePub you can convert and sell on Amazon, or the kind of ePub that won't
make your readers crazy with anger.

Since about 2008 LyX native format has become more and more "XML like"
without being either valid or well formed XML. If they just made LyX
into valid and well formed XML, creating our own converter, with Python
and Python's XML parser, will become a one person project. And such a
converter will by its very nature be semantic, it won't do stupid stuff
like  having paragraphs all have either "indented" or "unindented"
classes. That's a job for CSS, not for different types of paragraphs.
Converting LyX native format to a valid and well formed XML would make
export to ***ALL*** formats, those known and those yet to be discovered,
easy. And the converters would exist completely outside of LyX and
therefore would be small and modular.





Hi Steve,

There is a lot of wishes in your message. But I must warn, if you
ever happen to find this one person for the task, that their time is
better used within the project than outside of it. You can have a look
at the example of eLyXer, which has decided to go on its own. It still
has not caught up with the 2.2 format. Also, implementing things twice
is costly, and for what benefit? I do not see what edge a language like
Python has for this problem.

The problem rather seems to be finding this one person. So, any volunteer?

Hi all,

The second edition of my book "Manager's Guide to Technical
Troubleshooting" will ship as a 3.5" x 5.5" PDF instead of printed
paper. As you can imagine, for any reasonable facimile of decent
reading, I must embed the fonts used. However, most fonts that are
"free" to insert in a document are not free to insert in a document
that is distributed, because in that case you're giving away the font's
source, not just its appearance.


Professional font licences usually allow the distribution of the
necessary subset of the font along with documents, as XeTeX does. Also,
the SIL Open Font license states: "The requirement for fonts to remain
under this license does not apply to any document created using the Font
Software". I am surprised that other open-source font licences do not
appear to include similar exceptions.



As far as I know, the Liberation fonts don't have this problem, but
then again, they're not especially readable. What other fonts are
completely free to give away embedded inside a document you sell?



Adobe's free fonts are of the highest quality and are under the SIL Open
Source license. I eagerly await the release of the italics of Adobe's
Source Serif Pro. If not for this issue, I would recommend that you have 
a look.


There are forums on the internet where people who love to argue about

If you use \mathbb{1} in LyX, this produces the desired output
after loading a font package such as stix. Now, this does not look so
good in the LyX window currently. Then, what you can do is define a LyX
macro that outputs \mathbb{1}, but displays like \bf{1} insie LyX, for

larger.  I am using LyX 2.2.0, with Qt 4.8.7, which is standard on
debian testing.



I recommend compiling LyX 2.2.0 with Qt 5.6. The latter knows about
high-dpi monitors, and it uses the system settings to select the
appropriate magnification.

I just type \coloneqq in a math inset in LyX 2.2.2 and LyX recognized it
(but pdflatex bombed on it with the same error you saw). So I went to
Document > Settings > Math Options and changed "mathtools" from  "Load
automatically" to "Load always", and the document compiled. Maybe LyX
lost the ability to recognized that \coloneqq requires mathtools (or one
of a few other packages)?



This bug was in master, before being fixed at 338cef2a9. It seems that 
unfortunately 8603655 was backported without the fix. The solution is to 
backport 338cef2a9 (attached--Richard?). You can fix your local 
installation by replacing the symbols file with the attached.

Subject: [PATCH] Fix regression of 88603655

The XHTML entries were added in the wrong field, if they are given we need
extra xhtml requires. The order is inconsistent, there are discussions on the
list about that but for now I'll use the existing order to fix the export tests.

The format of the lib/symbols file does not support "" for empty strings.
One would have to use x for fields that are not set (this is a hack), but
actually we know how to fill the extra field.

(cherry-pick of commit 338cef2a)

Re: Fragility

Le 18/11/2016 à 12:36, F M Salter a écrit :

I would like to raise a question for everyone about what I am
describing as fragility in LyX.

I use Lyx as a method of recording my own thinking on various
subjects including mathematical analyses, a tool to annotate material
(usually academic papers which can not be annotated directly) and to
prepare papers for publication.  I feel that the fragility I am
detecting may be increasing and would then be attributibe directly to
LyX.  However, I am increasingly using more advanced techniques and
these may be the cause of the events which am noting rather than with
LyX itself.




Dear Frank,

My recommendation is to take the time to help with the detailed
recording of the bugs you experience, like you have begun to do, on the
bug tracker at http://www.lyx.org/trac/wiki/BugTrackerHome. I have the
same experience that with more advanced use, one sees more bugs. This is
surely because lyx allows many different uses, including ones not
thought about in advance by developers. Sometimes bugs also appear
with new releases. Surely, with everybody using lyx differently, it is
hard to get proper testing before a release. I started reporting bugs a
few years ago, and many have been fixed since. Patience pays off.

What I can't get used to is what happens when I am inside a (big)
formula. Namely, if I use ctrl+arrow I go to to the end (or beginning,
depending the arrow) of the formula, which is the same that I get using
the Home/End keys.
On the contrary, with ctrl+arrow I would like to be driven to the
end/beginning of current logical element, that is the same place where
the cursor would be if I hit shift+arrow.

So, my question is: can it be changed?
I tried to change some setting in keyboard shortcuts, but without luck.
Maybe I could not figure out the right one.


It cannot be changed with the current code. However, if you manage to
describe what should be done, we can take advantage (or will in next
major release) of the symbol category: binary operation (+ - * etc),
binary relation (< > = etc), operators (\lim \cos etc), open ( ( [ {
etc), close and a couple other categories.

If you come up with a scheme, we can try to use it for Ctrl-Right and
friends.



The new behaviour for Ctrl(+Shift)+Arrows suggested by this discussion
is now in master (981f065b). For now it skips "words" of symbols that
have the same mathclass. But, if somebody comes up with a better scheme,
it should be easy to improve it.

Hello Patrick, try adding "Provides mathrsfs 1" to the local format.

Re: No implication symbol

I just encountered something goofy, and I'm not sure if it's a LyX bug
or something odd about what's installed on my system. When I try to
compile the attached document (LyX 2.2.2, Linux Mint 18.1, TeXLive) I'm
told that \implies is an undefined control sequence. Looking at the
source window, LyX is not loading any math-related packages. If I go
into document settings and change amsmath from "load automatically" to
"load always", things work.

To be honest, I'm not sure what LaTeX packages provide \implies. If in
fact it's not in base LaTeX, shouldn't LyX recognize that it requires
amsmath?

I don't recall encountering this before, so I'm guessing that I'm
missing a TeXLive package, but I have no idea which.

This is fixed for 2.2.3, see http://www.lyx.org/trac/ticket/10467

Insert > Frame options ?

AFAICT, if you choose beamer(flex inserts) for document, then there is
no
menu item "(Insert > Frame options)".  This only appears if you choose
"beamer" for document.


You need to use the flex insets with the beamer document class.
(Unfortunately, there is no way at present to enforce this requirement.)

Richard


So if I use beamer-flex.inc from Guillaume Munch <g...@lyx.org>, then if I try
to insert a frame using insert > custom insets > Frame, there is no way to
then set frame options.  This can only be done using the lyx standard way of
inserting a frame: choosing Frame from environment dropdown list, which will
then activate the "Insert > Frame options" option.  Do I understand
correctly?


Strange. Here it works correctly if I use only beamer-flex.layout. The
version of beamer-flex.inc you point to correctly defines Argument 3 :
"Frame Options". Has the behaviour changed between 2.2 and 2.3?

Hello, it is a good idea to automatically reload background files. This is
not so simple, though, because the change notification can happen at random
times and it is not clear that the code is ready for this. I have an idea
to make it work, but this will need to wait that I am back from holidays.
It is best to open a ticket for now.
