I am trying to piece together a simple literate programming system that takes HTML as input and spews out source files. The program that "tangles" code fragments in the HTML into source text will be in XSLT.
Org mode is almost but not quite perfect for generating the HTML I'd like. I'm writing to ask if I'm overlooking features that are close to what I want to do, or advice about whether it makes sense to extend org this way and, if so, what work is entailed. (I'm aware of the existing literate programming features in org but they are pretty far from what I'm looking for, I think.) Right now, I can write something like this: #+BEGIN_SRC C printf ("hello world\n"); #+END_SRC and, via HTML export, get: <pre class="src src-C">printf("hello world\n"); </pre> What I'd really like is the ability to do this: #+BEGIN_SRC C name="Say goodnight, Gracey." printf ("Goodnight, Gracey\n"); #+END_SRC #+BEGIN_SRC C name="main routine" file="burns.c" #include <stdio.h> int main (int argc, char * argv[]) { //{{say goodnight, gracey}} return 0; } #+END_SRC and get: <i>Say goodnight, Gracey.</i>: <pre class="src src-C" id="say_goodnight_gracey"> printf ("Goodnight Gracey\n"); </pre> <i>main routine</i>: <pre class="src src-C" id="main_routine" file="burns.c"> #include <stdio.h> int main (int argc, char * argv[]) { <a href="#say_goodnight_gracey"><i>//{say goodnight, gracey}}</i></a> return 0; } </pre> You can probably see how if I could get those mangled "id" attributes in there, along with the hyperlinks, it's pretty easy to tangle the result to produce a source file like: #include <stdio.h> int main (int argc, char * argv[]) { printf ("Goodnight, Gracey\n"); return 0; } Any suggestions on what I would need to do to get code blocks like this? The precise details of the particular HTML mark-up are a little bit flexible. Huge "bonus points" if I can specify arbitrary attributes (not just "id" and "file") *and* introduce spans with a specific "id" in code. Like: #+BEGIN_SRC C id="print something" params="thing rest" printf (/*{thing}*/, /*{rest}*/); #+END_SRC for <pre ... id="print_something" params="thing rest"> printf (<span ... name="thing">/*thing*/</span>, ...); </pre> and #+BEGIN_SRC id="main routine" ... ... int main (int argc, char * argv[]) { //{{print something}thing={"argc is %d\n"}rest={argc}} return 0; } #+END_SRC for the obvious HTML expansion, all to ultimately generate (through the XSLT code): ... int main (...) { printf ("argc is %d\n", argc); ... } Thanks, -t
