There are two relevant document class options:

* "fleqn" (flush left equation), which aligns the equation to the left. 
Used by itself, though, it leaves the equation number on the right.


* "leqno" (left equation number), which puts the equation number on the 
left. Used by itself, it centers the equation still.


BUT, if you use BOTH options, then you get what you want.

How to do it in LyX? Look at Document> Settings> Document Class. The 
"Custom" field allows you to enter class options. In your case, you 
could enter "fleqn,leqno". Any class options can be entered here.


However, LyX also has native support for this under Document> Settings> 
Math Options. The Formula Numbering Side option is self-explanatory. You 
would want "Left". This adds "leqno" behind the scenes. The other one is 
the Indent Formulas checkbox. The tooltip explains what it does: It 
indents instead of centering equations. So you can check that. If you 
leave it at "Default", then it just adds "fleqn"; you can also, however, 
control the indent here by selecting "Custom" and entering a length 
(which gets set as the \mathindent).


This is all in the Math manual, under Help.

Re: older lyx file will not open

[Ivan Werning]

Solved!

Thanks so much Stephan! This was it.

I installed Python by way of...
 xcode-select --install
and I now have Python 3.9.6

I'm sorry I didn't notice the previously reported Ventura issue, as I only
ran into this problem when I was trying to convert a file. Newer files were
loading. So I didn't search for Ventura issues in the forum.

LyX rocks and this mail list rocks. Thanks again Stephan.

Hi Ivan,

did you upgrade macOS and what was your previous version?

Most of the time users did an upgrade from macOS 12.3 or earlier. The upgrade 
process removes one crucial utility (python) from the system and replaces it by 
a new one which asks the users for download and install of the newer version. 
One has to notice it, interpret is and agree with.

See the ticket in LyX’s bug tracker: https://www.lyx.org/trac/ticket/12523

To check for this you may open a Terminal session and type the command
python3 -V

Either you get a version info or you’ll be asked to download and install the 
real software. This is required to keep LyX working.

BR,
Stephan

1. Somewhat.  When I go "full screen" from half-width, I restore
correctly.  When I go "full screen" from full width, it returns to
something like half width (not the previous full width).  This is observed
with BetterTouchTool running.  If I quit it, then both approaches appear to
restore correctly.
2. macOS 12.5
3. Version 2.4.0-alpha3
(February 14, 2021)

Qt Version (run-time): 5.12.9
Qt Version (compile-time): 5.12.9
Python detected: python3 -tt

Hope this helps,

older lyx file will not open

[Ivan Werning]

Hi

Help! I'm having trouble with an important older LyX file not opening in
LyX.

I'm a long time LyX user here. I am having trouble with an old file from
2014 that was created by LyX 2.1. I'm on a 2017 intel mac running OS 13.0.1
(Ventura).

When I try to open it in 2.3.6.2 I get filename.lyx  is from an older
version of LyX and the lyx2lyx script failed to convert it.

#LyX 2.1 created this file. For more info see http://www.lyx.org/
\lyxformat 474
\begin_document
\begin_header
\textclass article


I tried downloading earlier versions of Lyx to no avail. I completely
failed with 2.1.5.  Here when I run LyX I am asked to reconfigure. I do,
but I'm not sure it works.

The error messages I get are different:

The module basic has been requested by

this document but has not been found in the list of

available modules. If you recently installed it, you

probably need to reconfigure LyX.


Hit OK then...


The module theorems-ams has been requested by

this document but has not been found in the list of

available modules. If you recently installed it, you

probably need to reconfigure LyX.


The module natbib has been requested by

this document but has not been found in the list of

available modules. If you recently installed it, you

probably need to reconfigure LyX.


And it finally opens the file with a Parse error box complaining "Layout
`Proposition' was not found."


At this point I have the file fully open, but it will not compile. Nor do I
know what to do with it to take it to a newer version. I get no Export
options and I tried copy pasting into the newer LyX and that did not work
(I get again "[filname] is from an older version of LyX and the lyx2lyx
script failed to convert it.")


Any help would be much appreciated! Thanks.

Do you know of programs that do store undo information, BTW?


My submission: vim.


Good to know, thanks.

Can you reproduce this bug?

[Scott Kostyshak]

Dear all,

Can you reproduce this bug on your system?

  https://www.lyx.org/trac/ticket/12435

It's helpful to know the type of systems on which it can be reproduced.
Specifically, it will be helpful to figure out whether the bug only
surfaces on certain operating systems, and only with certain
configurations.

Here is the recipe to reproduce the bug:

  1. Maximize (non-fullscreen) the window
  2. Enter Full screen mode
  3. Exit Full screen.

After step 3, does the LyX window return to the state after step (1)?
i.e., is the window maximized?

If you try to reproduce it, please state:

1. Can you reproduce the bug?
2. Your operating system and version number (version number is
   especially helpful for macOS users).
3. Copy/paste the info from Help > About.


Here's my own responses to the 3 questions:

1. No. (the window is correctly restored as maximized after 3 for me).
2. Ubuntu 22.04.
3. Pasted info is below:
  
   Version 2.4.0dev
   (Sunday, December 4, 2022)
   
   Built from git commit hash abd69b06
   Qt Version (run-time): 5.15.3 on platform xcb
   Qt Version (compile-time): 5.15.3
   Python detected: python3 -tt

Thanks!

Re: Copying and pasting equations from LyX into other packages?

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.

Copying and pasting equations from LyX into other packages?

[oliver.bond]

Hello,

 

Does LyX have an option to copy and paste a piece of LaTeX code in raw
format, i.e. removing any trace of macros that were used to generate the
code?

 

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:

 



 

I would like to be able to use a command to copy and paste the LaTeX code
