mod_autoindex string pluggability

[Sven Dowideit]

Hello Everyone,

I'm scratching an itch to make mod_autoindex output what I want, and
would love to know what, if anything would make the changes merge-able.

In its simplest form, I'd like apache to be able to give me an index in
JSON format - previously, I've parsed the html in javascript, but
somehow I think I can do better.

While I was reading the code (today) it occurred to me that there are a
lot of if statements throughout, which could be eliminated by moving
(obscuring) the output strings to a switchable container (right now I'm
using arrays of strings for my simplicity - I don't know this codebase
any better than you know me :)

so here is the kind of thing I started to do (partial diff, its all
really kind of dull - I've extracted the HTML/XHTML strings into another
similarly replaceable array):


#define STRING_INDEX_START   0
#define STRING_INDEX_END     1

const char *table_index_string[] = {
  "  <table>\n   <tr>",
  "</table>\n"
};

const char *table_index_string_stylesheet[] = {
  "  <table id=\"indexlist\">\n   <tr class=\"indexhead\">",
  "</table>\n"
};

const char *fancy_index_string[] = {
  "<pre>",
  "</pre>\n"
};

const char *default_index_string[] = {
  "<ul>",
  "</ul>\n"
};

/* set the default string set (choose alternatives based on user conf
options) */
const char **index_string = default_index_string;
