Re: Bug? Reading math mode formulas
Hello,
Tanks to Jean-Pierre for the solution he gave me. Note that since it
is not possible to insert directly 8bits characters in math mode, one
have to use \acute, \grave... commands if one wants to use accentuated
characters (to get é you have to type "\acute e"). See Jean-Pierre's
examples below.

Just do it:
M-m m \frac M-m m abc... gives
\begin_inset Formula \( \frac{\textrm{abc}}{\textrm{eff}} \)
\end_inset
(I've replaced g by f to show that the ligature works).
If you want an accented character, you may have it
\begin_inset Formula \( \frac{\textrm{abc}}{\acute{\textrm{e}}\textrm{ff}} \)
\end_inset
but as you can see, this is quite different of the result obtained with
\begin_inset Formula \( \frac{\textrm{abc}}{\testac } \)
\end_inset
once
\newcommand{\testac}{\mbox{éff}}
is defined in the preamble.
If you are a typographic addict, you will make a difference between a math accent
on letter e and a real é letter...

Hello,
How was this equation entered? From LyX or via reLyX?
I added Alejandro as Cc: to have his view on the question, since I do
not see the problem. For reference, the equation was
\begin_inset Formula \( \frac{\mbox {\textrm {abc}}}{\mbox {\textrm {efg}}} \)
\end_inset
which seems fine to me, and lyx says:
Line ~30: Math parse error: Expected {. Maybe you forgot to enclose an argument in {}

Math Panic, expect problems!
So, Alejandro, is that a bug, or a formula that LyX is not supposed to

I inserted a math display box, then "\mbox" then "{" (LyX inserted the closing

typed some characters. I saved the file and spaces where inserted
between \textrm and the accolade. This extra space makes LyX unable
to read properly the formula.
Use of \mbox in math mode, which is often used in plain LateX, should be
IMHO avoided in LyX because mathed does not
change from math to text mode and back as LaTeX does.
In the given example, the roman text sould be typed in in the so called
« math text mode »
Using a \newcommand offers a workaround when \mbox is really needed, as
it has been pointed out recently.

Use of \mbox in math mode, which is often used in plain LateX, should be
IMHO avoided in LyX because mathed does not
change from math to text mode and back as LaTeX does.
In the given example, the roman text sould be typed in in the so called
« math text mode »
Using a \newcommand offers a workaround when \mbox is really needed, as
it has been pointed out recently.

You mean I don't need to insert a mbox and that inserting textrm
directly would be suffisant ?

Just do it:
M-m m \frac M-m m abc... gives
\begin_inset Formula \( \frac{\textrm{abc}}{\textrm{eff}} \)
\end_inset
(I've replaced g by f to show that the ligature works).
If you want an accented character, you may have it
\begin_inset Formula \( \frac{\textrm{abc}}{\acute{\textrm{e}}\textrm{ff}} \)
\end_inset
but as you can see, this is quite different of the result obtained with
\begin_inset Formula \( \frac{\textrm{abc}}{\testac } \)
\end_inset
once
\newcommand{\testac}{\mbox{éff}}
is defined in the preamble.
If you are a typographic addict, you will make a difference between a math accent
on letter e and a real é letter...

Since it was inserted from LyX, Mathed should be able to read it or at least to prevent the problem, so it's a bug. But since there are better ways to insert this kind of expressions, as pointed out by other users, this bug has no priority for the current version. Greets, Alejandro
