示例1: OnTypeChar
public void OnTypeChar(IVsTextView pView, string ch)
{
if (ch == "{")
{
// add a closing "}" if it makes a complete expression or condition where one doesn't exist otherwise
_TextSpan selection;
pView.GetSelectionSpan(out selection);
IVsTextLines buffer;
pView.GetBuffer(out buffer);
string before;
buffer.GetLineText(0, 0, selection.iStartLine, selection.iStartIndex, out before);
int iLastLine, iLastColumn;
buffer.GetLastLineIndex(out iLastLine, out iLastColumn);
string after;
buffer.GetLineText(selection.iEndLine, selection.iEndIndex, iLastLine, iLastColumn, out after);
var existingResult = _grammar.Nodes(new Position(new SourceContext(before + ch + after)));
var expressionHits = existingResult.Rest.GetPaint()
.OfType<Paint<Node>>()
.Where(p => p.Begin.Offset <= before.Length && before.Length <= p.End.Offset && (p.Value is ExpressionNode || p.Value is ConditionNode));
// if a node exists normally, do nothing
if (expressionHits.Count() != 0)
return;
var withCloseResult = _grammar.Nodes(new Position(new SourceContext(before + ch + "}" + after)));

.OfType<Paint<Node>>()
.Where(p => p.Begin.Offset <= before.Length && before.Length <= p.End.Offset && (p.Value is ExpressionNode || p.Value is ConditionNode));
// if a close brace doesn't cause a node to exist, do nothing
if (withCloseHits.Count() == 0)
return;
// add a closing } after the selection, then set the selection back to what it was
