Creates a new TextChangeEventArgs object.

Gets the new offset where the specified offset moves after this document change.

Creates TextChangeEventArgs for the reverse change.

Allows for low-level line tracking.

The methods on this interface are called by the TextDocument's LineManager immediately after the document has changed, *while* the DocumentLineTree is updating. Thus, the DocumentLineTree may be in an invalid state when these methods are called. This interface should only be used to update per-line data structures like the HeightTree. Line trackers must not cause any events to be raised during an update to prevent other code from seeing the invalid state. Line trackers may be called while the TextDocument has taken a lock. You must be careful not to dead-lock inside ILineTracker callbacks.

Is called immediately before a document line is removed.

Is called immediately before a document line changes length. This method will be called whenever the line is changed, even when the length stays as it is. The method might be called multiple times for a single line because a replacement is internally handled as removal followed by insertion.

Is called immediately after a line was inserted.

The new line The existing line before the new line

Indicates that there were changes to the document that the line tracker was not notified of. The document is in a consistent state (but the line trackers aren't), and line trackers should throw away their data and rebuild the document.

Notifies the line tracker that a document change (a single change, not a change group) has completed. This method gets called after the change has been performed, but before the event is raised.

The TextAnchor class references an offset (a position between two characters). It automatically updates the offset when text is inserted/removed in front of the anchor.

Use the property to get the offset from a text anchor. Use the method to create an anchor from an offset. The document will automatically update all text anchors; and because it uses weak references to do so, the garbage collector can simply collect the anchor object when you don't need it anymore. Moreover, the document is able to efficiently update a large number of anchors without having to look at each anchor object individually. Updating the offsets of all anchors usually only takes time logarithmic to the number of anchors. Retrieving the property also runs in O(lg N). Usage:

TextAnchor anchor = document.CreateAnchor(offset);
            ChangeMyDocument();
            int newOffset = anchor.Offset;

Gets the text location of this anchor.

Thrown when trying to get the Offset from a deleted anchor.

Gets the offset of the text anchor.

Thrown when trying to get the Offset from a deleted anchor.

Controls how the anchor moves.

Anchor movement is ambiguous if text is inserted exactly at the anchor's location. Does the anchor stay before the inserted text, or does it move after it? The property will be used to determine which of these two options the anchor will choose. The default value is .

Specifies whether the anchor survives deletion of the text containing it. false: The anchor is deleted when the a selection that includes the anchor is deleted. true: The anchor is not deleted.

Gets whether the anchor was deleted.

When a piece of text containing an anchor is removed, then that anchor will be deleted. First, the property is set to true on all deleted anchors, then the events are raised. You cannot retrieve the offset from an anchor that has been deleted. This deletion behavior might be useful when using anchors for building a bookmark feature, but in other cases you want to still be able to use the anchor. For those cases, set = true.

Occurs after the anchor was deleted.

Due to the 'weak reference' nature of text anchors, you will receive the Deleted event only while your code holds a reference to the TextAnchor object.

Gets the line number of the anchor.

Thrown when trying to get the Offset from a deleted anchor.

Gets the column number of this anchor.

Thrown when trying to get the Offset from a deleted anchor.

Defines how a text anchor moves.

When text is inserted at the anchor position, the type of the insertion determines where the caret moves to. For normal insertions, the anchor will move after the inserted text.

Behaves like a start marker - when text is inserted at the anchor position, the anchor will stay before the inserted text.

Behave like an end marker - when text is inserted at the anchor position, the anchor will move after the inserted text.

A read-only view on a (potentially mutable) text source. The IDocument interface derives from this interface.

The search character Start index of the area to search. Length of the area to search. The last index where the search term was found; or -1 if no occurrence was found. The search proceeds backwards from (startIndex+count) to startIndex. This is different than the meaning of the parameters on string.LastIndexOf!

Gets the index of the last occurrence of the specified search text in this text source.

The search text Start index of the area to search. Length of the area to search. String comparison to use. The last index where the search term was found; or -1 if no occurrence was found. The search proceeds backwards from (startIndex+count) to startIndex. This is different than the meaning of the parameters on string.LastIndexOf!

Represents a version identifier for a text source.

Versions can be used to efficiently detect whether a document has changed and needs reparsing; or even to implement incremental parsers. It is a separate class from ITextSource to allow the GC to collect the text source while the version checkpoint is still in use.

Gets whether this checkpoint belongs to the same document as the other checkpoint.

Returns false when given null.

Compares the age of this checkpoint to the other checkpoint.

This method is thread-safe. Raised if 'other' belongs to a different document than this version. -1 if this version is older than . 0 if this version instance represents the same version as . 1 if this version is newer than .

Gets the changes from this checkpoint to the other checkpoint. If 'other' is older than this checkpoint, reverse changes are calculated.

Usually returns , but if line was deleted due to the "\r\n" merge, returns the previous line.

Gets the location of the next new line character, or SimpleSegment.Invalid if none is found.

Static helper methods for working with text.

Finds the next new line character starting at offset.

The text source to search in. The starting offset for the search. The string representing the new line that was found, or null if no new line was found. The position of the first new line starting at or after , or -1 if no new line was found.

Gets whether the specified string is a newline sequence.

Normalizes all new lines in to be .

Gets the newline sequence used in the document at the specified line.

Gets all whitespace (' ' and '\t', but no newlines) before offset.

The text source. The offset where the whitespace ends. The segment containing the whitespace.

Gets the leading whitespace segment on the document line.

Gets the trailing whitespace segment on the document line.

Gets a single indentation segment starting at - at most one tab or spaces.

The text source. The offset where the indentation segment starts. The size of an indentation unit. See . The indentation segment. If there is no indentation character at the specified , an empty segment is returned.

Gets whether the character is whitespace, part of an identifier, or line terminator.

Gets the next caret position.

The text source. The start offset inside the text source. The search direction (forwards or backwards). The mode for caret positioning. The offset of the next caret position, or -1 if there is no further caret position in the text source. This method is NOT equivalent to the actual caret movement when using VisualLine.GetNextCaretPosition. In real caret movement, there are additional caret stops at line starts and ends. This method treats linefeeds as simple whitespace.

Contains predefined offset change mapping types.

Normal replace. Anchors in front of the replaced region will stay in front, anchors after the replaced region will stay after. Anchors in the middle of the removed region will be deleted. If they survive deletion, they move depending on their AnchorMovementType.

This is the default implementation of DocumentChangeEventArgs when OffsetChangeMap is null, so using this option usually works without creating an OffsetChangeMap instance. This is equivalent to an OffsetChangeMap with a single entry describing the replace operation.

First the old text is removed, then the new text is inserted. Anchors immediately in front (or after) the replaced region may move to the other side of the insertion, depending on the AnchorMovementType.

This is implemented as an OffsetChangeMap with two entries: the removal, and the insertion.

The text is replaced character-by-character. Anchors keep their position inside the replaced text. Anchors after the replaced region will move accordingly if the replacement text has a different length than the replaced text. If the new text is shorter than the old text, anchors inside the old text that would end up behind the replacement text will be moved so that they point to the end of the replacement text.

On the OffsetChangeMap level, growing text is implemented by replacing the last character in the replaced text with itself and the additional text segment. A simple insertion of the additional text would have the undesired effect of moving anchors immediately after the replaced text into the replacement text if they used AnchorMovementStyle.BeforeInsertion. Shrinking text is implemented by removing the text segment that's too long; but in a special mode that causes anchors to always survive irrespective of their setting. If the text keeps its old size, this is implemented as OffsetChangeMap.Empty.

Like 'Normal', but anchors with = Default will stay in front of the insertion instead of being moved behind it.

Creates a new RopeTextSource.

Returns a clone of the rope used for this text source.

RopeTextSource only publishes a copy of the contained rope to ensure that the underlying rope cannot be modified.

Represents a simple segment (Offset,Length pair) that is not automatically updated on document changes.

Gets the overlapping portion of the segments. Returns SimpleSegment.Invalid if the segments don't overlap.

Gets the inorder successor of the node.

Gets the inorder predecessor of the node.

A tree of TextAnchorNodes.

Swaps the anchors stored in the two nodes.

Finds the node at the specified offset. After the method has run, offset is relative to the beginning of the returned node.

This class is the main class of the text model. Basically, it is a with events.

Thread safety: However, there is a single method that is thread-safe: (and its overloads).

Verifies that the current thread is the documents owner thread. Throws an if the wrong thread accesses the TextDocument.

The TextDocument class is not thread-safe. A document instance expects to have a single owner thread and will throw an when accessed from another thread. It is possible to change the owner thread using the method.

Transfers ownership of the document to another thread. This method can be used to load a file into a TextDocument on a background thread and then transfer ownership to the UI thread for displaying the document.

The owner can be set to null, which means that no thread can access the document. But, if the document has no owner thread, any thread may take ownership by calling .

Create an empty text document.

Create a new text document with the specified initial text.

Retrieves the text for a portion of the document.

Gets/Sets the text of the whole document.

This event is called after a group of changes is completed.

Is raised when one of the properties , , , changes.

Is raised before the document changes.

Here is the order in which events are raised during a document update: BeginUpdate() Start of change group (on undo stack) event is raised Insert() / Remove() / Replace() event is raised The document is changed TextAnchor.Deleted event is raised if anchors were in the deleted text portion event is raised EndUpdate() event is raised event is raised (for the Text, TextLength, LineCount properties, in that order) End of change group (on undo stack) event is raised If the insert/remove/replace methods are called without a call to BeginUpdate(), they will call BeginUpdate() and EndUpdate() to ensure no change happens outside of UpdateStarted/UpdateFinished. There can be multiple document changes between the BeginUpdate() and EndUpdate() calls. In this case, the events associated with EndUpdate will be raised only once after the whole document update is done. The listens to the UpdateStarted and UpdateFinished events to group all changes into a single undo step.

Is raised after the document has changed.

Creates a snapshot of the current text.

This method returns an immutable snapshot of the document, and may be safely called even when the document's owner thread is concurrently modifying the document. This special thread-safety guarantee is valid only for TextDocument.CreateSnapshot(), not necessarily for other classes implementing ITextSource.CreateSnapshot().

Creates a snapshot of a part of the current text.

Gets if an update is running.

Immediately calls , and returns an IDisposable that calls .

Begins a group of document changes. Some events are suspended until EndUpdate is called, and the will group all changes into a single action. Calling BeginUpdate several times increments a counter, only after the appropriate number of EndUpdate calls the events resume their work.

Replaces text.

The starting offset of the text to be replaced. The length of the text to be replaced. The new text. The offsetChangeMappingType determines how offsets inside the old text are mapped to the new text. This affects how the anchors and segments inside the replaced region behave.

Replaces text.

The starting offset of the text to be replaced. The length of the text to be replaced. The new text. The offsetChangeMap determines how offsets inside the old text are mapped to the new text. This affects how the anchors and segments inside the replaced region behave. If you pass null (the default when using one of the other overloads), the offsets are changed as in OffsetChangeMappingType.Normal mode. If you pass OffsetChangeMap.Empty, then everything will stay in its old place (OffsetChangeMappingType.CharacterReplace mode). The offsetChangeMap must be a valid 'explanation' for the document change. See . Passing an OffsetChangeMap to the Replace method will automatically freeze it to ensure the thread safety of the resulting DocumentChangeEventArgs instance.

Use segment.Contains(offset, 0) to detect whether a segment (end inclusive) contains offset; use segment.Contains(offset, 1) to detect whether a segment (end exclusive) contains offset.

Gets whether fully contains the specified segment.

A segment that can be put into a .

A can be stand-alone or part of a . If the segment is stored inside a TextSegmentCollection, its Offset and Length will be updated by that collection. When the document changes, the offsets of all text segments in the TextSegmentCollection will be adjusted accordingly. Start offsets move like AnchorMovementType.AfterInsertion, end offsets move like AnchorMovementType.BeforeInsertion (i.e. the segment will always stay as small as possible). If a document change causes a segment to be deleted completely, it will be reduced to length 0, but segments are never automatically removed from the collection. Segments with length 0 will never expand due to document changes, and they move as AfterInsertion. Thread-safety: a TextSegmentCollection that is connected to a may only be used on that document's owner thread. A disconnected TextSegmentCollection is safe for concurrent reads, but concurrent access is not safe when there are writes. Keep in mind that reading the Offset properties of a text segment inside the collection is a read access on the collection; and setting an Offset property of a text segment is a write access on the collection.

Setting this property to another value will acquire mouse capture and activate the mouse selection mode. If mouse capture cannot be acquired, MouseSelectionMode will stay unchanged. Currently, the setter only supports the values None, Normal and Rectangular.

Code that updates only the caret but not the selection can cause confusion when keys like 'Delete' delete the (possibly invisible) selected text and not the text around the caret. So we'll ensure that the caret is inside the selection. (when the caret is not in the selection, we'll clear the selection) This method is invoked using the Dispatcher so that code may temporarily violate this rule (e.g. most 'extend selection' methods work by first setting the caret, then the selection), it's sufficient to fix it after any event handlers have run.

Temporarily allows positioning the caret outside the selection. Dispose the returned IDisposable to revert the allowance.

The text area only forces the caret to be inside the selection when other events have finished running (using the dispatcher), so you don't have to use this method for temporarily positioning the caret in event handlers. This method is only necessary if you want to run the WPF dispatcher, e.g. if you perform a drag'n'drop operation.

Highlights the specified document line.

The line to highlight. A line object that represents the highlighted sections.

Enforces a highlighting state update (triggering the HighlightingStateChanged event if necessary) for all lines up to (and inclusive) the specified line number.

Notification when the highlighter detects that the highlighting state at the beginning of the specified lines has changed. fromLineNumber and toLineNumber are both inclusive; the common case of a single-line change is represented by fromLineNumber == toLineNumber. During highlighting, the highlighting of line X will cause this event to be raised for line X+1 if the highlighting state at the end of line X has changed from its previous state. This event may also be raised outside of the highlighting process to signalize that changes to external data (not the document text; but e.g. semantic information) require a re-highlighting of the specified lines.

For implementers: there is the requirement that, during highlighting, if there was no state changed reported for the beginning of line X, and there were no document changes between the start of line X and the start of line Y (with Y > X), then this event must not be raised for any line between X and Y (inclusive). Equal input state + unchanged line = Equal output state. See the comment in the HighlightingColorizer.OnHighlightStateChanged implementation for details about the requirements for a correct custom IHighlighter. Outside of the highlighting process, this event can be raised without such restrictions.

A kind of List<T>, but more efficient for random insertions/removal. Also has cheap Clone() and SubRope() implementations.

This class is not thread-safe: multiple concurrent write operations or writes concurrent to reads have undefined behavior. Concurrent reads, however, are safe. However, clones of a rope are safe to use on other threads even though they share data with the original rope.

Creates a new rope representing the empty string.

input is null.

Creates a rope from a part of the array. This operation runs in O(N).

input is null.

Creates a new rope that lazily initalizes its content.

The length of the rope that will be lazily loaded. The callback that provides the content for this rope. will be called exactly once when the content of this rope is first requested. It must return a rope with the specified length. Because the initializer function is not called when a rope is cloned, and such clones may be used on another threads, it is possible for the initializer callback to occur on any thread. Any modifications inside the rope will also cause the content to be initialized. However, insertions at the beginning and the end, as well as inserting this rope into another or using the method, allows constructions of larger ropes where parts are lazily loaded. However, even methods like Concat may sometimes cause the initializer function to be called, e.g. when two short ropes are concatenated.

Clones the rope. This operation runs in linear time to the number of rope nodes touched since the last clone was created. If you count the per-node cost to the operation modifying the rope (doing this doesn't increase the complexity of the modification operations); the remainder of Clone() runs in O(1).

Creates a new rope and initializes it with a part of this rope. Runs in O(lg N) plus a per-node cost as if this.Clone() was called.

offset or length is outside the valid range. This method counts as a read access and may be called concurrently to other read accesses.

Concatenates two ropes. The input ropes are not modified. Runs in O(lg N + lg M).

This method counts as a read access and may be called concurrently to other read accesses.

Concatenates multiple ropes. The input ropes are not modified.

This method counts as a read access and may be called concurrently to other read accesses.

Gets/Sets a single character. Runs in O(lg N) for random access. Sequential read-only access benefits from a special optimization and runs in amortized O(1).

Creates a string from the rope. Runs in O(N).

A string consisting of all elements in the rope as comma-separated list in {}. As a special case, Rope<char> will return its contents as string without any additional separators or braces, so it can be used like StringBuilder.ToString(). This method counts as a read access and may be called concurrently to other read accesses.

Balances this node and recomputes the 'height' field. This method assumes that the children of this node are already balanced and have an up-to-date 'height' value.

Copies from the array to this node.

Copies from this node to the array.

Splits this leaf node at offset and returns a new node with the part of the text after offset.

Gets the root node of the subtree from a lazily evaluated function node. Such nodes are always marked as shared. GetContentNode() will return either a Concat or Leaf node, never another FunctionNode.

TextReader implementation that reads text from a rope.

Creates a new RopeTextReader. Internally, this method creates a Clone of the rope; so the text reader will always read through the old version of the rope if it is modified.

Represents a string with a segment. Similar to System.ArraySegment<T>, but for strings instead of arrays.

Creates a new StringSegment.

Gets the string used for this segment.

Gets the start offset of the segment with the text.

Gets the length of the segment.
