This page describes some of the internal workings of PmWiki by explaining how some of the functions in pmwiki.php work. For a more brief list/overview on functions useful to for instance cookbook writers, see Cookbook:Functions.

FmtPageName($fmt, $pagename)

Returns $fmt, with $variable and $[internationalisation] substitutions performed, under the assumption that the current page is pagename. See PmWiki.Variables for an (incomplete) list of available variables, PmWiki.Internationalizations for internationalisation.

This is one of the major functions in PmWiki, see PmWiki.FmtPageName for
lots of details.

Markup($name, $when, $pattern, $replace)

Adds a new markup to the conversion table. Described in greater detail at PmWiki.CustomMarkup.

This function is used to insert translation rules into the PmWiki’s
translation engine. The arguments to Markup() are all strings, where:

$name
The string names the rule that is inserted. If a rule of the same name already exists, then this rule is ignored.
$when
This string is used to control when a rule is to be applied relative to other rules. A specification of “<xyz” says to apply this rule prior to the rule named “xyz”, while “>xyz” says to apply this rule after the rule “xyz”. See CustomMarkup for more details on the order of rules.
$pattern
This string is a regular expression that is used by the translation engine to look for occurences of this rule in the markup source.
$replace
This string will replace the matched text when a match occurs.

MarkupToHTML($pagename, $str)

Converts the string $str containing PmWiki markup into the corresponding HTML code, assuming the current page is $pagename.

Also see: Cookbook:Functions#MarkupToHTML

mkdirp($dir)

The function mkdirp($dir) creates a directory, $dir, if it doesn’t
already exist, including any parent directories that might be needed. For
each directory created, it checks that the permissions on the directory are
sufficient to allow PmWiki scripts to read and write files in that
directory. This includes checking for restrictions imposed by PHP’s
safe_mode setting. If mkdirp() is unable to successfully create a
read/write directory, mkdirp() aborts with an error message telling the
administrator the steps to take to either create $dir manually or give
PmWiki sufficient permissions to be able to do it.

MakeLink($pagename, $target, $txt, $suffix, $fmt)

The function MakeLink($pagename, $target, $txt, $suffix, $fmt) returns a ???. It’s arguments are as follows:

 $pagename is the source page
 $target is where the link should go
 $txt is the value to use for ‘$LinkText’ in the output 
 $suffix is any suffix string to be added to $txt
 $fmt is a format string to use

If $txt is NULL or not specified, then it is automatically computed from $target.

If $fmt is NULL or not specified, then MakeLink uses the default
format as specified by the type of link. For page links this
means the $LinkPageExistsFmt and $LinkPageCreateFmt variables,
for intermap-style links it comes from either the $IMapLinkFmt
array or from $UrlLinkFmt. Inside of the formatting strings,
$LinkUrl is replaced by the resolved url for the link, $LinkText
is replaced with the appropriate text, and $LinkAlt is replaced
by any “title” (alternate text) information associated with the
link.
