Re: CGI interface to lilypond
For an individual person, lilypond-book can already process html
files, so there is nothing extra needed.
Thank you.
I think I didn't explain myself very well.
My goal is to embed the lilypond source in HTML source. Something like this
html
head
titleExample/title
/head
body
This is my new song: img
src=localorpublic/cgi-bin/lilypondmagic.cgi?\relative c { \clef bass
c d e c }
/body
/html
My understanding from
http://lilypond.org/doc/v2.12/Documentation/user/lilypond-program/HTML#HTML
is that lilypond-book by itself does not work like this and it not
support this - a wrapper CGI application is required.
To prove how this can work with LaTeX (and a CGI wrapper called
mathtex), load this into your browser.
html
head
titleExample/title
/head
body
This is my new theorem: img
src=http://www.forkosh.dreamhost.com/mathtex.cgi?\sqrt{x^2}=x;
/body
/html
If you want to have it for a multi-user situation like a wiki,
then search for lilypond wiki or mediawiki or similar terms on
the mailist; it has been discussed before.
This is slightly off-topic, but for everyone's benefit, this is what I
know about the MediaWiki situation.
An unsecure extension is available here
http://www.mediawiki.org/wiki/Extension:LilyPond
This works fine for private (intranet) wikis and for public wikis that
are not notable enough to be subject to DoS attacks.
For bigger, public wikis (notably Wikipedia), someone has implemented
a secure, generic framework that renders music and other stuff
http://wikisophia.org/wiki/Wikitex
http://modtex.org
My understanding is that development is almost done, but the project
is currently on a hiatus.
Thanks

If you are writing the html yourself, then why do you want a cgi
call? You get the desired output by running lilypond-book with
the [verbose] option.
It doesn't make any sense to regenerate the output every time
somebody looks at the webpage.

If you don't want a multi-user situation, then I don't see the
point of a cgi script...?

Yes, which is why I suggested that you look into safe mode.

Re: CGI interface to lilypond
If you are writing the html yourself, then why do you want a cgi call? I'm not necessarily writing the html myself. A CGI interface is useful for the same use cases that mathtex enables with LaTeX. It doesn't make any sense to regenerate the output every time somebody looks at the webpage. Images are not regenerated, they are generated once and then cached. For more details, see http://www.forkosh.dreamhost.com/source_mathtex.html Anyway, I take it that no such CGI interface exists then. I'll let you know of any developments on my side, thanks for now.

are serious security issues involved -- it is not impossible to
mitigate the risks, but be prepared for an amount of work.
There has been some discussion about developing safer and easier
ways of doing these things, but so far nobody has been seriously
interested. (I define seriously interested as willing to spend
over 20 hours working on it, not counting time on emails)
If you're seriously interested in such things, then please search
the mailist for lilypond server and safe mode; you should be
able to get an idea of what's involved.

Hi there,
I am new to lilypond.
I am wondering if there exists an interface like mathtex, for lilypond.
For those who don't know mathtex, it's a way of embedding rendered TeX
images directly and easily in an HTML page (and therefore in wikis, in
blogs etc), through a relatively simple CGI service.
So, in your web page, you can just type your formula like this
img
src=http://www.forkosh.dreamhost.com/mathtex.cgi?x=\frac{-b\pm\sqrt{b^2-4ac}}{2a};
and voila, the image is rendered and embedded. (You would of course
prefer to build the service locally and use that, instead of using a
publicly available service, but that's the idea.)
I think it's quite clever and neat. You can read the whole story here
http://www.forkosh.dreamhost.com/source_mathtex.html
My understanding is that it should not be difficult to implement
something like this for lilypond. Perhaps through lilypond-book and
latex, or maybe just via lilypond directly.
I am keen to develop this (or at least give it a try), but first I
would like to make sure that I wouldn't be reinventing the wheel.
Any other input from you guys would also be welcome, of course.
Thank you, and anyway thanks for this superlative tool.
