Hi Bernard,
I looked over your patch and it looks good. I took out your "Wish List"
section from the Literate.lyx, since I don't really think it belongs there.
Here is the slightly modified patch (attached). I also took the liberty of
creating a ChangeLog entry for this work to make it easier on whoever ends
up committing this change.
I am quoting your wish list here. You wrote:

Yes, it's great! Thanks, Edmar.

This is not really necessary. The "File->Build Program" menu item
does what you want.
You can also set up your lyxrc in such a way that the "Build Program" menu
item is bound to a button in the toolbar. Look at the Extended.lyx for
more info, but I do this:
\begin_toolbar
\layouts
\add layout Scrap
\add layout LaTeX
\add layout LyX-Code
\separator
\add buffer-view
\add buffer-typeset
\add build-program
[...]
Since I have my \build_command set to "build-script" (which is a one-line
shell script: ``notangle -Rbuild-script $1 | sh'') I can just press the
"Build Program" button on the toolbar.

Yes, this would be nice but difficult. I got around this problem in
one of my projects by embedding a perl script which created a Makefile.
The <<build-script>> section then did something like this:
notangle -RMakeMake.pl mysource.nw | perl > Makefile
make
It's a bit of a hack, but I actually found that writing the Makefile in
terms of this embedded perl program was useful in the expository parts
of the Literate Program.

This too would be nice but I think it's outside the scope of LyX or
noweb.
You can pull your tangled code into any variety of syntax-sensitive
editors afterwards.

These are good points. Perhaps you can create another Literate.lyx
patch (after the current one is accepted).

It's not quite that simple, but I've now done this.
You need to use lyx to --export the noweb file (which currently
requires an X server be running for lyx), then you notangle and compile
the noweb file.
Can one of you fine LyX developers go ahead and commit this attached
patch? It works quite well for me and I use the Literate Programming
stuff all the time.
You will have to ``cvs add'' the lib/build-listerrors shell script (which
is in the tiny attached gzipped tar archive).
Thanks!
