Detailed Description

Highlighting-file based keyword completion for the editor.

This model offers completion of language-specific keywords based on information taken from the kate syntax files. It queries the highlighting engine to get the correct context for a given cursor position, then suggests all keyword items from the XML file for the active language.

Member Function Documentation

◆ completionInvoked()

void KateKeywordCompletionModel::completionInvoked	(	KTextEditor::View *	view,
		const KTextEditor::Range &	range,
		InvocationType	invocationType )

overridevirtual

This function is responsible to generating / updating the list of current completions.

The default implementation does nothing.

When implementing this function, remember to call setRowCount() (or implement rowCount()), and to generate the appropriate change notifications (for instance by calling QAbstractItemModel::reset()).

Parameters

view	The view to generate completions for
range	The range of text to generate completions for
invocationType	How the code completion was triggered

Reimplemented from KTextEditor::CodeCompletionModel.

Definition at line 24 of file katekeywordcompletion.cpp.

◆ completionRange()

KTextEditor::Range KateKeywordCompletionModel::completionRange	(	KTextEditor::View *	view,
		const KTextEditor::Cursor &	position )

overridevirtual

This function returns the completion range that will be used for the current completion.

This range will be used for filtering the completion list and will get replaced when executing the completion

The default implementation will work for most languages that don't have special chars in identifiers. Since 5.83 the default implementation takes into account the wordCompletionRemoveTail configuration option, if that option is enabled the whole word the cursor is inside is replaced with the completion, however if it's disabled only the text on the left of the cursor will be replaced with the completion.

Parameters

view	The view to generate completions for
position	Current cursor position

Returns: the completion range

Reimplemented from KTextEditor::CodeCompletionModelControllerInterface.

Definition at line 83 of file katekeywordcompletion.cpp.

◆ data()

QVariant KateKeywordCompletionModel::data	(	const QModelIndex &	index,
		int	role ) const

overridevirtual

Implements QAbstractItemModel.

Definition at line 130 of file katekeywordcompletion.cpp.

◆ index()

QModelIndex KateKeywordCompletionModel::index	(	int	row,
		int	column,
		const QModelIndex &	parent = QModelIndex() ) const

overridevirtual

Reimplemented from QAbstractItemModel::index().

The default implementation returns a standard QModelIndex as long as the row and column are valid.

Reimplemented from KTextEditor::CodeCompletionModel.

Definition at line 45 of file katekeywordcompletion.cpp.

◆ matchingItem()

KTextEditor::CodeCompletionModelControllerInterface::MatchReaction KateKeywordCompletionModel::matchingItem ( const QModelIndex & matched )

overridevirtual

Called whenever an item in the completion-list perfectly matches the current filter text.

Parameters

matched The index that is matched

Returns: Whether the completion-list should be hidden on this event. The default-implementation always returns HideListIfAutomaticInvocation

Reimplemented from KTextEditor::CodeCompletionModelControllerInterface.

Definition at line 161 of file katekeywordcompletion.cpp.

◆ parent()

QModelIndex KateKeywordCompletionModel::parent ( const QModelIndex & index ) const

overridevirtual

Reimplemented from QAbstractItemModel::parent().

The default implementation returns an invalid QModelIndex for all items. This is appropriate for non-hierarchical / flat lists of completions.

Reimplemented from KTextEditor::CodeCompletionModel.

Definition at line 36 of file katekeywordcompletion.cpp.

◆ rowCount()

int KateKeywordCompletionModel::rowCount ( const QModelIndex & parent = QModelIndex() ) const

overridevirtual

Reimplemented from QAbstractItemModel::rowCount().

The default implementation returns the value set by setRowCount() for invalid (toplevel) indices, and 0 for all other indices. This is appropriate for non-hierarchical / flat lists of completions

Reimplemented from KTextEditor::CodeCompletionModel.

Definition at line 64 of file katekeywordcompletion.cpp.

◆ shouldAbortCompletion()

bool KateKeywordCompletionModel::shouldAbortCompletion	(	KTextEditor::View *	view,
		const KTextEditor::Range &	range,
		const QString &	currentCompletion )

overridevirtual

This function decides if the completion should be aborted.

Called after every change to the range (eg. when user entered text)

The default implementation will return true when any special character was entered, or when the range is empty.

Parameters

view	The view to generate completions for
range	The completion range
currentCompletion	The text typed so far

Returns: true, if the completion should be aborted, otherwise false

Reimplemented from KTextEditor::CodeCompletionModelControllerInterface.

Definition at line 99 of file katekeywordcompletion.cpp.

◆ shouldHideItemsWithEqualNames()

bool KateKeywordCompletionModel::shouldHideItemsWithEqualNames ( ) const

overridevirtual

When multiple completion models are used at the same time, it may happen that multiple models add items with the same name to the list.

This option allows to hide items from this completion model when another model with higher priority contains items with the same name.

Returns: Whether items of this completion model should be hidden if another completion model has items with the same name

Reimplemented from KTextEditor::CodeCompletionModelControllerInterface.

Definition at line 125 of file katekeywordcompletion.cpp.

◆ shouldStartCompletion()

bool KateKeywordCompletionModel::shouldStartCompletion	(	KTextEditor::View *	view,
		const QString &	insertedText,
		bool	userInsertion,
		const KTextEditor::Cursor &	position )

overridevirtual

This function decides if the automatic completion should be started when the user entered some text.

The default implementation will return true if the last character in insertedText is a letter, a number, '.', '_' or '>'

Parameters

view	The view to generate completions for
insertedText	The text that was inserted by the user
userInsertion	Whether the text was inserted by the user using typing. If false, it may have been inserted for example by code-completion.
position	Current cursor position

Returns: true, if the completion should be started, otherwise false

Reimplemented from KTextEditor::CodeCompletionModelControllerInterface.
