I am working with music notation software called lilypond. It is able to
compile text-like notation markup language of it's own, into various formats,
among them png file.
Another command which comes with lilypond is it's companion
lilypond-book, which will compile any document containing <lilypond> tag,
and put in that place code snippet like this one:
<p>
<a href="10/lily-9f8f7b5d.ly">
<img align="middle" border="0" src="10/lily-9f8f7b5d.png"
alt="[image of music]">
</a>
</p>
So my wish, as a huge fan of VIM is to use it's filtering capabilities and
automate this kind of job, so for example when I'm in a document like this
one:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title>html-with-notation</title>
</head>
<body>
This is some text, before including lilypond notation file
And here is the melody:
<lilypondfile>andantino.ly</lilypondfile>/* <-- TAG THAT WILL BE RECOGNIZED BY LILYPOND-BOOK */
Enjoy!
</body>
</html>
..I would like to replace that <lilypond> tag, with the generated output
from lilypond-book command. But it's not that simple, because lilypond-book
does not write to a stdout but to a file, called stdin.html. (it names it
like that automatically, recognizing that the input is comming from there)
So while running this:
:.!lilypond-book -f html - 2>/dev/null
// ( with errors redirected to `/dev/null` to prevent polluting my buffer with messages being output.)
I don't get back nothing, which of course is expected, as all of the output has gone to a file.
How would I now read back that stdin.html file after all processing is done
from the part of lilypond-book, into that current line I am on, in my vim
buffer? All in one go, of course, without doing manually :r stdin.html.
Also as a bonus, would it be possible before reading that stdin.html into a buffer, process it with pandoc to convert it into a markdown first, in cases when I am working on markdown files?
