  • $text - Text to process
  • $re - Regular expression that matches tag expressions to remove
  • \%map - Reference to a hash to contain the removed blocks

Return value: $text with blocks removed

used to extract from $text comment type tags like <!DOCTYPE blah>

WARNING: if you want to take out <!-- comments --> you will need to re-write all the takeOuts to use a different placeholder

ObjectMethod *putBackProtected (\$text,\%map,$callback) -> $text

Return value: $text with blocks added back

  • \$text - reference to text to process
  • \%map - map placeholders to blocks removed by takeOutBlocks

StaticMethod getReferenceRE ($web,$topic,%options) -> $re

  • $web, $topic - specify the topic being referred to, or web if $topic is undef.
  • %options - the following options are available
    • interweb - if true, then fully web-qualified references are required.
    • grep - if true, generate a GNU-grep compatible RE instead of the default Perl RE.
    • url - if set, generates an expression that will match a TWiki URL that points to the web/topic, instead of the default which matches topic links in plain text.
Generate a regular expression that can be used to match references to the specified web/topic. Note that the resultant RE will only match fully qualified (i.e. with web specifier) topic names and topic names that are wikiwords in text. Works for spaced-out wikiwords for topic names.

The RE returned is designed to be used with s///

  • args string containing name of form field

In addition to the name of a field args can be appended with a commas followed by a string format (\d+)([,\s*]\.\.\.)?). This supports the formatted search function $formfield and is used to shorten the returned string or a hyphenated string.

StaticMethod *protectFormFieldValue ($value,$attrs) -> $html

Given the value of a form field, and a set of attributes that control how to display that value, protect the value from further processing.

The protected value is determined from the value of the field after:

  • newlines are replaced with <br> or the value of $attrs->{newline}
  • processing through breakName if $attrs->{break} is defined
  • escaping of $vars if $attrs->{protectdollar} is defined
  • | is replaced with &#124; or the value of $attrs->{bar} if defined

Package =TWiki::Render

This module provides most of the actual HTML rendering code in TWiki.

On this page:

ClassMethod new ($session)

Creates a new renderer with initial state from preference values (NEWTOPICBGCOLOR, NEWTOPICFONTCOLOR NEWTOPICLINKSYMBOL LINKTOOLTIPINFO)

ObjectMethod renderParent ($web,$topic,$meta,$params) -> $text

Render parent meta-data

ObjectMethod renderMoved ($web,$topic,$meta,$params) -> $text

Render moved meta-data

ObjectMethod *renderFormField ($web,$topic,$meta,$params) -> $text

Render meta-data for a single formfield

ObjectMethod makeAnchorName ($anchorName,$compatibilityMode) -> $anchorName

  • $anchorName -
  • $compatibilityMode -

Build a valid HTML anchor name

ObjectMethod internalLink ($theWeb,$theTopic,$theLinkText,$theAnchor,$doLink,$doKeepWeb) -> $html

Generate a link.

SMELL: why can topic be spaced out? is this to support auto squishing of Spaced Topic Naming? and lowercase Spaced Topic Naming

  • $theWeb - the web containing the topic
  • $theTopic - the topic to be lunk
  • $theLinkText - text to use for the link
  • $theAnchor - the link anchor, if any
  • $doLinkToMissingPages - boolean: false means suppress link for non-existing pages
  • $doKeepWeb - boolean: true to keep web prefix (for non existing Web.TOPIC)

Called by _handleWikiWord and _handleSquareBracketedLink and by Func::internalLink

Calls _renderWikiWord, which in turn will use Plurals.pm to match fold plurals to equivalency with their singular form

SMELL: why is this available to Func?

ObjectMethod renderFORMFIELD (%params,$topic,$web) -> $html

Returns the fully rendered expansion of a tag.

ObjectMethod *getRenderedVersion ($text,$theWeb,$theTopic) -> $html

The main rendering function.

StaticMethod *verbatimCallBack

Callback for use with putBackBlocks that replaces < and > by their HTML entities &lt; and &gt;

ObjectMethod TML2PlainText ($text,$web,$topic,$opts) -> $plainText

Clean up TWiki text for display as plain text without pushing it through the full rendering pipeline. Intended for generation of topic and change summaries. Adds nop tags to prevent TWiki subsequent rendering; nops get removed at the very end.

Defuses TML.

$opts:

  • showvar - shows %VAR% names if not expanded
  • expandvar - expands %VARS%
  • nohead - strips ---+ headings at the top of the text
  • showmeta - does not filter meta-data

ObjectMethod *protectPlainText ($text) -> $tml

Protect plain text from expansions that would normally be done duing rendering, such as wikiwords. Topic summaries, for example, have to be protected this way.

ObjectMethod *makeTopicSummary ($theText,$theTopic,$theWeb,$theFlags) -> $tml

Makes a plain text summary of the given topic by simply trimming a bit off the top. Truncates to $TMTRUNC chars or, if a number is specified in $theFlags, to that length.

ObjectMethod *takeOutProtected (\$text,$re,\%map) -> $text

  • $text - Text to process
  • $re - Regular expression that matches tag expressions to remove
  • \%map - Reference to a hash to contain the removed blocks

Return value: $text with blocks removed

used to extract from $text comment type tags like <!DOCTYPE blah>

WARNING: if you want to take out <!-- comments --> you will need to re-write all the takeOuts to use a different placeholder

ObjectMethod *putBackProtected (\$text,\%map,$tag,$newtag,$callBack) -> $text

Return value: $text with blocks added back

  • \$text - reference to text to process
  • \%map - map placeholders to blocks removed by takeOutBlocks

Reverses the actions of takeOutProtected.

ObjectMethod takeOutBlocks (\$text,$tag,\%map) -> $text

  • $text - Text to process
  • $tag - XHTML-style tag.
  • \%map - Reference to a hash to contain the removed blocks

Return value: $text with blocks removed

Searches through $text and extracts blocks delimited by a tag, appending each onto the end of the @buffer and replacing with a token string which is not affected by TWiki rendering. The text after these substitutions is returned.

Parameters to the open tag are recorded.

This is different to takeOutProtected, because it requires tags to be on their own line. it also supports a callback for post- processing the data before re-insertion.

ObjectMethod putBackBlocks (\$text,\%map,$tag,$newtag,$callBack) -> $text

Return value: $text with blocks added back

  • \$text - reference to text to process
  • \%map - map placeholders to blocks removed by takeOutBlocks
  • $tag - Tag name processed by takeOutBlocks
  • $newtag - Tag name to use in output, in place of $tag. If undefined, uses $tag.
  • $callback - Reference to function to call on each block being inserted (optional)

Reverses the actions of takeOutBlocks.

Each replaced block is processed by the callback (if there is one) before re-insertion.

Parameters to the outermost cut block are replaced into the open tag, even if that tag is changed. This allows things like <verbatim class=''> to be mapped to <pre class=''>

Cool, eh what? Jolly good show.

And if you set $newtag to '', we replace the taken out block with the valuse itself

  • which i'm using to stop the rendering process, but then at the end put in the html directly (for tag. ---++ ObjectMethod *renderRevisionInfo* ($web,$topic,$meta,$rev,$format) -> $string Obtain and render revision info for a topic. * =$web= - the web of the topic * =$topic= - the topic * =$meta= if specified, get rev info from here.

If =$tml= is not set, all HTML will be removed. In non-tml, lines are truncated to 70 characters. Differences are shown using + and - to indicate added and removed text. ---++ ObjectMethod *forEachLine* ($text,\&fn,\%options) -> $newText Iterate over each line, calling =\&fn= on each. \%options may contain: * =pre= => true, will call fn for each line in pre blocks * =verbatim= => true, will call fn for each line in verbatim blocks * =noautolink= => true, will call fn for each line in =noautolink= blocks The spec of \&fn is sub fn( \$line, \%options ) -> $newLine; the %options hash passed into this function is passed down to the sub, and the keys =in_pre=, =in_verbatim= and =in_noautolink= are set boolean TRUE if the line is from one (or more) of those block types. The return result replaces $line in $newText. ---++ StaticMethod *replaceTopicReferences* ($text,\%options) -> $text Callback designed for use with forEachLine, to replace topic references. \%options contains: * =oldWeb= => Web of reference to replace * =oldTopic= => Topic of reference to replace * =spacedTopic= => RE matching spaced out oldTopic * =newWeb= => Web of new reference * =newTopic= => Topic of new reference * =inWeb= => the web which the text we are presently processing resides in * =fullPaths= => optional, if set forces all links to full web.topic form For a usage example see TWiki::UI::Manage.pm ---++ StaticMethod *replaceWebReferences* ($text,\%options) -> $text Callback designed for use with forEachLine, to replace web references. \%options contains: * =oldWeb= => Web of reference to replace * =newWeb= => Web of new reference For a usage example see TWiki::UI::Manage.pm ---++ ObjectMethod *replaceWebInternalReferences* (\$text,\%meta,$oldWeb,$oldTopic) Change within-web wikiwords in $$text and $meta to full web.topic syntax. \%options must include topics => list of topics that must have references to them changed to include the web specifier. ---++ StaticMethod *renderFormFieldArg* ($meta,$args) -> $text Parse the arguments to a $formfield specification and extract the relevant formfield from the given meta data. ---++ StaticMethod *breakName* ($text,$args) -> $text * =$text= - text to "break" * =$args= - string of format (\d+)([,\s*]\.\.\.)?) Hyphenates $text every $1 characters, or if $2 is "..." then shortens to $1 characters and appends "..." (making the final string $1+3 characters long) _Moved from Search.pm because it was obviously unhappy there, as it is a rendering function_
