Detailed Description

Content object implementation for representing flat text.

TextContent instances are immutable

Definition at line 35 of file TextContent.php.

Constructor & Destructor Documentation

◆ __construct()

TextContent::__construct (   $text,
  $model_id = CONTENT_MODEL_TEXT 
)
Parameters
string$text
string$model_id
Exceptions
MWException

Reimplemented in JsonContent, JavaScriptContent, and CssContent.

Definition at line 42 of file TextContent.php.

References AbstractContent\$model_id, and wfWarn().

Member Function Documentation

◆ convert()

TextContent::convert (   $toModel,
  $lossy = '' 
)

This implementation provides lossless conversion between content models based on TextContent.

Parameters
string$toModelThe desired content model, use the CONTENT_MODEL_XXX flags.
string$lossyFlag, set to "lossy" to allow lossy conversion. If lossy conversion is not allowed, full round-trip conversion is expected to work without losing information.
Returns
Content|bool A content object with the content model $toModel, or false if that conversion is not supported.

Content::convert()

Reimplemented from AbstractContent.

◆ copy()

TextContent::copy ( )
Note
Mutable subclasses MUST override this to return a copy!
Returns
Content $this

Implements Content.

Reimplemented in RevisionTestModifyableContent.

Definition at line 64 of file TextContent.php.

◆ diff()

TextContent::diff ( Content  $that,
Language  $lang = null 
)

Diff this content object with another content object.

Since
1.21
Parameters
Content$thatThe other content object to compare this content object to.
Language$langThe language object to use for text segmentation. If not given, $wgContentLang is used.
Returns
Diff A diff representing the changes that would have to be made to this content object to make it equal to $that.

Definition at line 198 of file TextContent.php.

References $lang, $wgContLang, AbstractContent\checkModelID(), Content\getModel(), Content\getNativeData(), getNativeData(), and global.

◆ fillParserOutput()

TextContent::fillParserOutput ( Title  $title,
  $revId,
ParserOptions  $options,
  $generateHtml,
ParserOutput $output 
)
protected

Fills the provided ParserOutput object with information derived from the content.

Unless $generateHtml was false, this includes an HTML representation of the content provided by getHtml().

For content models listed in $wgTextModelsToParse, this method will call the MediaWiki wikitext parser on the text to extract any (wikitext) links, magic words, etc.

Subclasses may override this to provide custom content processing. For custom HTML generation alone, it is sufficient to override getHtml().

Parameters
Title$titleContext title for parsing
int$revIdRevision ID (for {{REVISIONID}})
ParserOptions$optionsParser options
bool$generateHtmlWhether or not to generate HTML
ParserOutput&$outputThe output object to fill (reference).

Reimplemented from AbstractContent.

Reimplemented in WikitextContent, JsonContent, and GadgetDefinitionContent.

References $html, $options, $output, $wgParser, $wgTextModelsToParse, getHtml(), AbstractContent\getModel(), getNativeData(), global, and ParserOutput\setText().

◆ getHighlightHtml()

TextContent::getHighlightHtml ( )
protected

Generates an HTML version of the content, for display.

This default implementation returns an HTML-escaped version of the raw text content.

Note
The functionality of this method should really be implemented in getHtml(), and subclasses should override getHtml() if needed. getHighlightHtml() is kept around for backward compatibility with extensions that already override it.
Deprecated:
since 1.24. Use getHtml() instead. In particular, subclasses overriding getHighlightHtml() should override getHtml() instead.
Returns
string An HTML representation of the content

Definition at line 290 of file TextContent.php.

References getNativeData().

◆ getHtml()

TextContent::getHtml ( )
protected

Generates an HTML version of the content, for display.

Used by fillParserOutput() to provide HTML for the ParserOutput object.

Subclasses may override this to provide a custom HTML rendering. If further information is to be derived from the content (such as categories), the fillParserOutput() method can be overridden instead.

For backwards-compatibility, this default implementation just calls getHighlightHtml().

Returns
string An HTML representation of the content

Reimplemented in WikitextContent, CssContent, and JavaScriptContent.

◆ getNativeData()

◆ getSize()

TextContent::getSize ( )

Returns the text's size in bytes.

Returns
int

Implements Content.

Definition at line 85 of file TextContent.php.

References getNativeData().

◆ getTextForSearchIndex()

TextContent::getTextForSearchIndex ( )

Returns the text represented by this Content object, as a string.

Returns
string The raw text.

Implements Content.

Definition at line 128 of file TextContent.php.

References getNativeData().

◆ getTextForSummary()

TextContent::getTextForSummary (   $maxLength = 250)

Returns a textual representation of the content suitable for use in edit summaries and log messages.

Since
1.21
Parameters
int$maxLengthMaximum length of the summary text.
Returns
string The summary text.

Implements Content.

Reimplemented in WikitextContent.

Definition at line 68 of file TextContent.php.

References $wgContLang, getNativeData(), and global.

◆ getWikitextForTransclusion()

TextContent::getWikitextForTransclusion ( )

Returns attempts to convert this content object to wikitext, and then returns the text string.

The conversion may be lossy.

Note
this allows any text-based content to be transcluded as if it was wikitext.
Returns
string|bool The raw text, or false if the conversion failed.

Implements Content.

Definition at line 140 of file TextContent.php.

References CONTENT_MODEL_WIKITEXT, and convert().

◆ isCountable()

TextContent::isCountable (   $hasLinks = null)

Returns true if this content is not a redirect, and $wgArticleCountMethod is "any".

Parameters
bool | null$hasLinksIf it is known whether this content contains links, provide this information here, to avoid redundant parsing to find out.
Returns
bool

Implements Content.

Definition at line 100 of file TextContent.php.

References $wgArticleCountMethod, global, and AbstractContent\isRedirect().

◆ normalizeLineEndings()

static TextContent::normalizeLineEndings (   $text)
static

Do a "\\r\\n" -> "\\n" and "\\r" -> "\\n" transformation as well as trim trailing whitespace.

This was formerly part of Parser::preSaveTransform, but for non-wikitext content models they probably still want to normalize line endings without all of the other PST changes.

Since
1.28
Parameters
string$text
Returns
string

Definition at line 163 of file TextContent.php.

Referenced by JsonContent\preSaveTransform(), and preSaveTransform().

◆ preSaveTransform()

TextContent::preSaveTransform ( Title  $title,
User  $user,
ParserOptions  $popts 
)

Returns a Content object with pre-save transformations applied.

At a minimum, subclasses should make sure to call TextContent::normalizeLineEndings() either directly or part of Parser::preSaveTransform().

Parameters
Title$title
User$user
ParserOptions$popts
Returns
Content
