user-defined functions (yet again)
I am fairly new to LyX. I have been disappointed to find that simple commands
defined via \newcommand and \DeclareMathOperator in the preamble (for example,
\newcommand{\sinc}{sinc}) appear as evil red text onscreen. In fact, they
look exactly the same as undefined (illegal!) commands. I got the impression
from the LyX manuals and user comments that LyX was pretty good at interpreting
and rendering user-defined commands. Have I misunderstood something, or am I
doing something wrong, or is there something wrong with my LyX installation?
(I realize there are several other threads with similar questions, but none of
them have a clear answer to this as far as I can tell.)
I am using LyX 1.6.7 on windows xp sp3.

RE: user-defined functions (yet again)
Thanks for the response Julien. I am starting to use math macros. But a
limitation of them is that I have to create them in LyX; they aren't
automatically generated when I import LaTeX files I have written by hand
(which I have a lot of!), and the result is a bunch of ugly formulas. One
of the main reasons I'm trying LyX is that it was claimed to be more
compatible with raw LaTeX than Scientific Word, which I have used for years.
I believe LyX will import your \newcommands and convert them to math
macros if the \newcommands appear after \begin{document}
Regarding the use of the preamble, section 15.2 Self-Defined Functions of
the math manual says that you can use the \DeclareMathOperator in the
preamble to define your own named functions such that the result is the
same ... as with a predefined function, which I took to mean it would look
onscreen like a predefined function. But then there is the footnote which
says self-defined functions are displayed in red, predefined ones in
black. If that means all LyX does is show the command name as ERT, then in
my opinion that is a somewhat weak (and somewhat misleading) feature.
That's a good point. I would recommend to send a message to the LyX
documentation team.
As a general note: LyX is free software and isn't backed up by any
company. Considering this, sometimes I find that what was accomplished
with LyX is quite amazing. However sometimes I find it is lacking a lot.
The great thing, though, is that it can be made better with such great
feedback like you already started to provide. And better yet you could
provide a patch which would properly import \newcommands from the
preamble of your .tex file into a .lyx doc.
First I was only a LyX user and then I started contributing to the
project when I saw that something was lacking. I would advise you the
same if you can, it will make LyX better and you can use it to import
your .tex files properly.
Cheers,
Julien
Thanks. I confirmed that \newcommand does work if it's within the document
environment, but not in the preamble (which seems odd to me, since the preamble
seems to be a pretty reasonable place to define commands). Also, it only works
if you import it, not if you enter it in manually from within LyX (again, not
something I expected, but perhaps understandable). Since LyX can handle
\newcommand, it shouldn't be hard to get \DeclareMathOperator to display nicely
also.
I am indeed impressed with what LyX can do, which is why I believe it can be
even better. I would love to contribute -- I actually had started planning out
something very similar to LyX about a decade ago -- but unfortunately I don't
have much spare time now. Maybe someday!
