Constructor & Destructor Documentation

LineEditor()

LineEditor::LineEditor	(	StringRef	ProgName,
		StringRef	HistoryPath = "",
		FILE *	In = stdin,
		FILE *	Out = stdout,
		FILE *	Err = stderr
	)

Create a LineEditor object.

Parameters

ProgName	The name of the current program. Used to form a default prompt.
HistoryPath	Path to the file in which to store history data, if possible.
In	The input stream used by the editor.
Out	The output stream used by the editor.

Member Function Documentation

getCompletionAction()

LineEditor::CompletionAction LineEditor::getCompletionAction	(	StringRef	Buffer,
		size_t	Pos
	)		const

Use the current completer to produce a CompletionAction for the given completion request.

If the current completer is a list completer, this will return an AK_Insert CompletionAction if each completion has a common prefix, or an AK_ShowCompletions CompletionAction otherwise.

Parameters

Buffer	The string to complete
Pos	The zero-based cursor position in the StringRef

setCompleter()

template<typename T >

void llvm::LineEditor::setCompleter ( T  Comp )

inline

Set the completer for this LineEditor.

A completer is a function object which takes arguments of type StringRef (the string to complete) and size_t (the zero-based cursor position in the StringRef) and returns a CompletionAction.

Definition at line 84 of file LineEditor.h.

setListCompleter()

template<typename T >

void llvm::LineEditor::setListCompleter ( T  Comp )

inline

Set the completer for this LineEditor to the given list completer.

A list completer is a function object which takes arguments of type StringRef (the string to complete) and size_t (the zero-based cursor position in the StringRef) and returns a std::vector<Completion>.
