示例1: CreateElisionBufferWithoutIndentation
public static IElisionBuffer CreateElisionBufferWithoutIndentation(
this IProjectionBufferFactoryService factoryService,
IEditorOptions editorOptions,
IContentType contentType,
IEnumerable<SnapshotSpan> exposedSpans)
{
var spans = new NormalizedSnapshotSpanCollection(exposedSpans);
if (spans.Count > 0)
{
// BUG(6335): We have to make sure that the spans refer to the current snapshot of
// the buffer.
var buffer = spans.First().Snapshot.TextBuffer;
var currentSnapshot = buffer.CurrentSnapshot;
spans = new NormalizedSnapshotSpanCollection(
spans.Select(s => s.TranslateTo(currentSnapshot, SpanTrackingMode.EdgeExclusive)));
}
contentType = contentType ?? factoryService.ProjectionContentType;
var elisionBuffer = factoryService.CreateElisionBuffer(
null, spans, ElisionBufferOptions.None, contentType);
if (spans.Count > 0)
{
var snapshot = spans.First().Snapshot;
var buffer = snapshot.TextBuffer;
// We need to figure out the shorted indentation level of the exposed lines. We'll
// then remove that indentation from all lines.
var indentationColumn = DetermineIndentationColumn(editorOptions, spans);
var spansToElide = new List<Span>();
foreach (var span in spans)
{
var startLineNumber = snapshot.GetLineNumberFromPosition(span.Start);
var endLineNumber = snapshot.GetLineNumberFromPosition(span.End);
for (var lineNumber = startLineNumber; lineNumber <= endLineNumber; lineNumber++)
{
var line = snapshot.GetLineFromLineNumber(lineNumber);
var lineOffsetOfColumn = line.GetLineOffsetFromColumn(indentationColumn, editorOptions);
spansToElide.Add(Span.FromBounds(line.Start, line.Start + lineOffsetOfColumn));
}
}
elisionBuffer.ElideSpans(new NormalizedSpanCollection(spansToElide));
}
return elisionBuffer;
}示例2: CoalesceSpans
internal static NormalizedSnapshotSpanCollection CoalesceSpans(NormalizedSnapshotSpanCollection normalizedSpans)
{
var snapshot = normalizedSpans.First().Snapshot;
// Coalesce the spans if there are a lot of them.
if (normalizedSpans.Count > CoalesceDifferenceCount)
{
// Spans are normalized. So to find the whole span we just go from the
// start of the first span to the end of the last span.
normalizedSpans = new NormalizedSnapshotSpanCollection(snapshot.GetSpanFromBounds(
normalizedSpans.First().Start,
normalizedSpans.Last().End));
}
return normalizedSpans;
