/*
** If zTarget is an interwiki link, return a pointer to a URL for that
** link target in memory obtained from fossil_malloc().  If zTarget is
** not a valid interwiki link, return NULL.
**
** An interwiki link target is of the form:
**
**       Code:PageName
**
** "Code" is a brief code that describes the intended target wiki.
** The code must be ASCII alpha-numeric.  No symbols or non-ascii
** characters are allows.  Case is ignored for the code.
** Codes are assigned by "intermap:*" entries in the CONFIG table.
** The link is only valid if there exists an entry in the CONFIG table
** that matches "intermap:Code".
**
** Each value of each intermap:Code entry in the CONFIG table is a JSON
** object with the following fields:
**
**    {
**      "base":  Base URL for the remote site.
**      "hash":  Append this to "base" for Hash targets.
**      "wiki":  Append this to "base" for Wiki targets.
**    }
**
** If the remote wiki is Fossil, then the correct value for "hash" 
** is "/info/" and the correct value for "wiki" is "/wiki?name=".
** If (for example) Wikipedia is the remote, then "hash" should be
** omitted and the correct value for "wiki" is "/wiki/".  
**
** PageName is link name of the target wiki.  Several different forms
** of PageName are recognized.
**
**    Path       If PageName is empty or begins with a "/" character, then
**               it is a pathname that is appended to "base".
**
**    Hash       If PageName is a hexadecimal string of 4 or more
**               characters, then PageName is appended to "hash" which
**               is then appended to "base".
**
**    Wiki       If PageName does not start with "/" and it is
**               not a hexadecimal string of 4 or more characters, then
**               PageName is appended to "wiki" and that combination is
**               appended to "base".
**
** See https://en.wikipedia.org/wiki/Interwiki_links for further information

## Interwiki Tag Map

  @ Include letters for each type of document for which unsafe HTML should
  @ be allowed.  For example, to allow unsafe HTML only for checked-in files,
  @ make this setting be just "<b>b</b>".  To allow unsafe HTML anywhere except
  @ in forum posts, make this setting be "<b>btw</b>".  The default is an
  @ empty string which means that Fossil never allows Markdown documents
  @ to generate unsafe HTML.
  @ (Property: "safe-html")</p>
  @ <hr />
  @ The current interwiki tag map is as follows:
  interwiki_append_map_table(cgi_output_blob());
  @ <p>Visit <a href="./intermap">%R/intermap</a> for details or to
  @ modify the interwiki tag map.
  @ <hr />
  onoff_attribute("Use HTML as wiki markup language",
    "wiki-use-html", "wiki-use-html", 0, 0);
  @ <p>Use HTML as the wiki markup language. Wiki links will still be parsed
  @ but all other wiki formatting will be ignored.</p>
  @ <p><strong>CAUTION:</strong> when
  @ enabling, <i>all</i> HTML tags and attributes are accepted in the wiki.

      is not a bullet or enumeration list item is rendered indented.
      Only a single level of indentation is supported by wiki.
      Use HTML for deeper indentation.

  5.  <b>Hyperlinks.</b>
      Text within square brackets <nowiki>("[...]")</nowiki> becomes a
      hyperlink. The target can be a wiki page name, the artifact ID of
      a check-in or ticket, the name of an image, a URL, or an
      [#intermap|interwiki link] of the form 
      "<i>Tag</i><b>:</b><i>PageName</i>".
      By default, the target is displayed as the text of the hyperlink.
      But you can specify alternative text after the target name
      separated by a "|" character.
      You can also link to internal anchor names using 
      <nowiki>[#anchor-name],</nowiki> providing you have added the necessary 
      "&lt;a name='anchor-name'&gt;&lt;/a&gt;" tag to your wiki page.

  7.  <b>Special Markup.</b>
      The &lt;nowiki&gt; tag disables all wiki formatting rules through
      the matching &lt;/nowiki&gt; element. The &lt;verbatim&gt; tag works
      like &lt;pre&gt; with the addition that it also disables all wiki
      and HTML markup through the matching &lt;/verbatim&gt;.

  *  (2.12.1): Fix client-side vulnerabilities discovered by Max Justicz.
  *  Security fix in the "[/help?cmd=git|fossil git export]" command.
     The same fix is also backported to version 2.10.1 and 2.11.1.

# Interwiki Links

Interwiki links are a short-hand notation for links that target
external wikis or websites.  For example, the following two
hyperlinks mean the same thing (assuming an appropriate [intermap](#intermap)
configuration):

  * [](wikipedia:Interwiki_links)
  * [](https://en.wikipedia.org/wiki/Interwiki_links)

Another example:  The Fossil Forum is hosted in a separate repository
from the Fossil source code.  This page is part of the
source code repository.  Interwiki links can be used to more easily
refer to the forum repository:

  * [](forum:d5508c3bf44c6393df09c)
  * [](https://fossil-scm.org/forum/info/d5508c3bf44c6393df09c)

## Advantages Over Full URL Targets

  *  Interwiki links are easier to write.  There is less typing,
     and fewer opportunities to make mistakes.

  *  Interwiki links are easier to read.  With well-chosen
     intermap tags, the links are easier to understand.

  *  Interwiki links continue to work after a domain change on the
     target.  If the target of a link moves to a different domain,
     an interwiki link will continue to work, if the intermap is adjusted,
     but a hard-coded link will be permanently broken.

  *  Interwiki links allow clones to use a different target domain from the
     original repository.

## Details

Fossil supports interwiki links in both the 
[Fossil Wiki](/wiki_rules) and [Markdown](/md_rules) markup
styles. An interwiki link consists of a tag followed a colon
and the link target:

> <i>Tag</i><b>:</b><i>PageName</i>

The Tag must consist of ASCII alphanumeric characters only - no
punctuation or whitespace or characters greater than U+007A.
The PageName is the link notation on the target wiki.
Three different classes of PageNames are recognized by Fossil:

  1.  <b>Path Links</b> &rarr; the PageName is begins with the "/" character
      or is an empty string.

  2.  <b>Hash Links</b> &rarr; the PageName is a hexadecimal number with
      at least four digits.

  3.  <b>Wiki Links</b> &rarr; An PageName that is not a Path or Hash.

The Intermap defines a base URL for each Tag.  Path links are appended
directly to the URL contained in the Intermap.  The Intermap can define
additional text to put in between the base URL and the PageName for
Hash and Wiki links, respectively.

<a name="intermap"></a>
## Intermap

The intermap defines a mapping from interwiki Tags to full URLs.  The
Intermap can be viewed and managed using the [fossil interwiki][iwiki]
command or the [/intermap][imap] webpages.

[iwiki]: /help?cmd=interwiki
[imap]: /help?cmd=/intermap

Each intermap entry stores, at a minimum, the base URL for the remote
wiki.  The intermap entry might also store additional path text that
is used for Hash and Wiki links.  If only the base URL is provided,
then the intermap will only allow Path style interwiki links.  The
Hash and Wiki style interwiki links are only allowed if the necessary
extensions for provided in the intermap.


## Disadvantages and Limitations

  *  Configuration is required.  The intermap must be set up correctly
     before interwiki links will work.  This contrasts with ordinary
     links that just work without any configuration.  Cloning a repository
     copies the intermap, but normal syncs to not keep the intermap in
     sync.  Use the "[fossil config pull interwiki][fcfg]" command to
     synchronize the intermap.

  *  The is no backlink tracking.  For ordinary intrawiki links, Fossil keeps
     track of both the source and target, and when displaying targets it
     commonly shows links to that target.  For example, if you mention a
     check-in as part of a comment of another check-in, that new check-in
     shows up in the "References" section of the target check-in.
     ([example](31af805348690958).  In other words, Fossil tracks not just
     "_source&rarr;target_", but it also tracks "_target&rarr;source_".
     But backtracking do not work for interwiki links, since the Fossil
     running on the target has no way of knowing scanning the source and
     hence has no way of knowing that it is a target of a link from the source.

[fcfg]: /help?cmd=config

## Intermap Storage Details

The intermap is stored in the CONFIG table of the repository database,
in entries with names of the form "<tt>interwiki:</tt><i>Tag</i>".  The
value for each such entry is a JSON string that defines the base URL
and extensions for Hash and Wiki links.
