Important

This API is not CLS-compliant.

Source represents one source file and manages the parsing and intellisense on this file and keeping things like the drop down combos in sync with the source and so on.

Remarks

A Source object represents the entire source file associated with a particular view. Information about the source file can be obtained from this class. However, the primary functionality of this class is to handle parsing operations on the source in support for IntelliSense operations and source file-specific editing operations such as adding comments to and removing comments from blocks of code and reporting parsing errors.

Notes to Inheritors

The base class supports all of the IntelliSense operations in coordination with methods on the LanguageService class (these are detailed in the Source class's method descriptions). If you:

• support different comment delimiters other than the standard C#/C++ delimiters,

• reformat code,

  and/or

• support advanced functionality for hidden regions (monitoring change of state, ensuring a span is visible, and marker-oriented context menu commands),

you must derive a class from the Source class and instantiate your class in CreateSource(IVsTextLines).

Notes to Callers

This class is instantiated by a call to the CreateSource(IVsTextLines) method. This is done when the CodeWindowManager object is instantiated (the Source object is passed to the CodeWindowManager constructor). A Colorizer object can be instantiated and passed to the Source class's constructor.

Constructors

Source(LanguageService, IVsTextLines, Colorizer)

Initializes a new instance of the Source class.

Properties

ChangeCount	Gets the number of changes made to the source file since it was opened.
ColorState	Gets or sets the IVsTextColorState object that is used in various parsing tasks.
CompletedFirstParse	Gets whether the parser has completed at least once.
CompletionSet	Gets the CompletionSet collection used for this instance of the Source class.
DirtySpan	Gets a range that identifies the changed lines in the source.
HandlesSnapshots
IsClosed	Gets the current state of the source file.

BeginParse()	Begins a full parsing operation either in the foreground or the background.

Close()	Determines whether the source file can be closed.
ColumnToVisiblePosition(Int32, Int32)	Return the column position that the user will see given the current tab size setting. This is the opposite of VisiblePositionToColumn
CommentBlock(TextSpan, String, String)	Called from Comment Selection. Default behavior is to insert block style comments at beginning and end of selection. Override to add custome behavior.
CommentLines(TextSpan, String)	Called from Comment Selection. Default behavior is to insert line style comments at beginning and end of selection. Override to add custome behavior.
CommentSpan(TextSpan)	Comments out the specified span of source.
Completion(IVsTextView, TokenInfo, ParseReason)	Starts an IntelliSense member completion operation.
CreateAuthoringSink(ParseReason, Int32, Int32)	Creates an instance of an AuthoringSink object for use in parsing operations.

CreateErrorTaskItem(TextSpan, MARKERTYPE, String)	Creates a new error task item for the Error List, for the supplied text, marker type, and file name.
CreateErrorTaskItem(TextSpan, String, String, TaskPriority, TaskCategory, MARKERTYPE, TaskErrorCategory)	Creates a new error task item for the Error List, for the supplied text, file name, message, priority, category, marker type, and error type.
CreateMethodData()	Creates a new instance of a MethodData object that handles the IntelliSense method tip mode.
DismissCompletor()	Removes the IntelliSense method tip or completion list from view, whichever was active.
Dispose()	Called in preparation of destroying this Source object.
ExecMarkerCommand(IVsHiddenRegion, Int32)	Executes the specified command on the specified region.
Finalize()	The class destructor, called just before the object is destroyed.
GetColorizer()	Gets the colorizer associated with this Source object.
GetCommentFormat()	Override this method if you want to provide different comment dilimiters. You can turn off commenting by setting Preferences.EnableCommenting to false.
GetDocumentSpan()	Gets the span occupied by the entire source file.
GetExpansionProvider()	Gets an expansion provider in support of code snippets.
GetFilePath()	Gets the file name of the source file.
GetHiddenTextSession()	Gets the hidden region manager if available.
GetLine(Int32)	Gets the text on the specified line.
GetLineCount()	Gets the number of lines in the source file.
GetLineIndexOfPosition(Int32, Int32, Int32)	Gets the line and column for the specified position.
GetLineLength(Int32)	Gets the length of the specified line.
GetMarkerCommandInfo(IVsHiddenRegion, Int32, String[], UInt32[])	Determines which marker commands can be shown on a context menu for the specified hidden region.
GetNewLine(Int32)	Gets the newline character used at the end of the specified line.
GetPairExtents(IVsTextView, Int32, Int32, TextSpan, TextSpan)	Gets the text spans for a matching pair (or triplet) of language elements.
GetPairExtents(IVsTextView, Int32, Int32, TextSpan)	Gets the span between a matching pair of language elements.
GetPositionOfLineIndex(Int32, Int32)	Gets the position corresponding to the given line and character offset location.
GetTaskProvider()	Gets the task provider that manages the error tasks.
GetText()	Gets all of the text of the source file.
GetText(Int32, Int32, Int32, Int32)	Gets the text between the specified locations.
GetText(TextSpan)	Gets the text included in the text span.
GetTextLines()	Gets the IVsTextLines object associated with this Source object.
GetTextUpToLine(Int32)	Gets the text from the source up to and including the given line number.
GetTipText(IVsHiddenRegion, String[])	Gets the text in the given hidden region to be used in a tool tip.

Recolorize(Int32, Int32)	Updates the syntax highlighting on the specified range of lines.
ReformatSpan(EditArray, TextSpan)	This method formats the given span using the given EditArray. The default behavior does nothing. So you need to override this method if you want formatting to work. An empty input span means reformat the entire document. You also need to turn on Preferences.EnableFormatSelection.

RemoveHiddenRegions()	Removes all hidden regions from the current view.
RemoveTask(DocumentTask)	Removes the specified error task from the error Task window.

UncommentLines(TextSpan, String)	Removes line comment characters from the beginning of each line in the given span.
UncommentSpan(TextSpan)	Uncomments the given span of text and returns the span of the uncommented block.
