Sorry if this is not the appropriate place for this. It has been a little while.

I have been experiencing the same problem. It seems to me that this IS a bug,
and while what has been proposed (use \underline instead of \underbar) works,
and is valuable input/information, it is a workaround to the bug, not a fix. The
bug still exists. At least, this is how I am reading the problem.

Any news on someone actually addressing the bug?

It's not exactly a bug in LyX, more like a quirk of LaTeX not (yet) addressed
by LyX.  See, for instance,
http://newsgroups.derkeiler.com/Archive/Comp/comp.text.tex/2009-11/msg00659.html.

That post led me to a LyX math-macro that defines a new command (I used 
\ubar but the name is arbitrary) that does the trick:

\begin_layout Standard
\begin_inset FormulaMacro
\renewcommand{\ubar}[1]{\underbar{\ensuremath{#1}}}
\end_inset

With this macro defined in the document body, you just type \ubar rather 
than \underbar in a math inset.  It seems to work with a variety of math
symbols, not just Greek letters.

I don't know any way to provide this in a module, though.  You can put the 
code in the preamble, but then LyX won't recognize it as a math macro.  So 
AFAIK your options are:

1.  insert the LaTeX code

\global\long\def\ubar#1{\underbar{\ensuremath{#1}}}

in the preamble (this can be done with a module), and in math insets type

\ubar\{

(which will generate an inset surrounded by braces), type your stuff in the
inset, and live with the fact that LyX does not display the underbar (but 
LaTeX will);

2.  create a document containing the macro definition in the body and save
it as a LyX template; or

3.  create a child document with the macro in it, and include the child in 
any document where you're going to feel an urge to use underbars.

This is bug #4565; I've amended the ticket to suggest the ensuremath fix.  
We'll see what happens.

Re: Is this a bug?? \underbar{\alpha} crashes...

[Erez Yerushalmi]

Let me add to this email that I'm using window-XP, Lyx 1.6.5.

Dear All,

I wonder if this is a bug??

When I use the \underbar I get an error message.  See them below.

In math box, I type
x
\underbar{x}
\underbar{\alpha}

What I get is the following.
First, x is italics.
Second, OK, x comes with underbar, *but* pdf is not italic.   Strange.
Third, crashes with the following errors:

$x$ $\underbar{x}$ $\underbar{\alpha}

$

I've inserted a begin-math/end-math symbol since I think

you left one out. Proceed, with fingers crossed.



and


$x$ $\underbar{x}$ $\underbar{\alpha}

$

I've deleted a group-closing symbol because it seems to be

spurious, as in `$x}$'. But perhaps the } is legitimate and

you forgot something else, as in `\hbox{$x}'. In such cases

the way to recover is to insert both the forgotten and the

deleted material, e.g., by typing `I$}'.

Am I missing something

Thanks a lot,  Erez

You don't need the braces, just press Spacebar to finish a command. For 
more info about formulas, have a look at the Math manual that you find 
in the Help menu of LyX.

This is correct. Variables are italic in math. That's the common

You need to use \underline instead of \underbar. You can alternatively 
use the corresponding math toolbar button to achieve this.

Re: Is this a bug?? \underbar{\alpha} crashes...

Hi Uwe

Thanks to your points!
Yes, I'm now using \underline,  instead, and problem solved!  :-)

*However*, Yes, I usually do number 1 and 2 like you said. I just used them
as an example of progression towards the bug.

So, the *problem* arises when I'm in math mode, and I type as usual:
 \underbar space, \alpha space, and I get my equation.  All seems fine.

However, when I PDF it, LyX *crashes*.

See LyX attachment like you asked for.

It doesn't crash here, I only get a LaTeX error. The reason is that \underbar is a text command and 
thus cannot handle Greek characters and other math constructs. You must use \underline.

However, when I PDF it, LyX *crashes*.

See LyX attachment like you asked for.
I'm using XP, Lyx 1.6.5

Yes, I'm now using \underline,  instead, and problem solved!  :-)


So, the *problem* arises when I'm in math mode, and I type as usual:
  \underbar space, \alpha space, and I get my equation.  All seems fine.

However, when I PDF it, LyX *crashes*.


It doesn't crash here, I only get a LaTeX error. The reason is that \underbar is a text command and 
thus cannot handle Greek characters and other math constructs. You must use \underline.
