Commented Unassigned: Autocomplete bugs with underscore [34165]

2manyQuestions — Mon, 17 Jun 2013 19:32:26 GMT

Hello,

the Autocompletion seems to bug for words that contain an underscore. If I have the following list:

test
test_2
testvar

and I enter "testv" then the Autocompletion list gets closed because no entry is found (AutoHide is enabled).

I allready checked Lexing.WordChars, here the underscore char is included correctly. Also AutoComplete.FillUpCharacters only contains ".([" and AutoComplete.StopCharacters doesn't contain any value, so it should work, right? Also AutoComplete.IsCaseSensitive is set to false.

The strange thing is that it sometimes does work, but I couldn't find out any regularity under which circumstances this happens.

Hi,

this works great, thank you very much! Never thought of changing the sorting order, very nice trick.

I had a very similar problem, and it comes down to sorting order.

You need to sort the auto complete list, using ordinal sorting rules, as that is what Scintilla uses. In the case above you need to order them in the auto complete list as:

test
textvar
test_2

If you are adding them manually/from some other source you could do:

editor.AutoComplete.List.Sort(new AutoCompleteSort());

where AutoCompleteSort is the following (note this is doing a case-insensitive sort as well):

/// <summary>
/// Custom comparer to use when sorting the AutoComplete list
/// </summary>
private class AutoCompleteSort : IComparer<string>
{
#region IComparer<string> Members

public int Compare(string x, string y)
{
return String.Compare(x, y, StringComparison.OrdinalIgnoreCase);
}

#endregion
}

Reopened Feature: Request: .ScrollToLine [25115]

Are you able to programming a new method Scrolling.ScrollToLine(n).
-Needs to Zero out the X value of horizontal scroll bar
-Needs to Set the line to equal the very TopLine of the Visible lines in the textbox
-Should really take the caret with it

Point 2 is not offered by any current scrolling capabiliteis and then .ScrollBy is hard to reverse calculate.

Reopened Issue: A problem with searches by ScintillaNet.FindReplace.Find(Range r, Regex findExpression, bool searchUp) and non-ASCII encodings [26168]

jacobslusser — Fri, 14 Jun 2013 07:32:04 GMT

A range returned by call of ScintillaNet.FindReplace.Find(Range r, Regex findExpression, bool searchUp) for UTF-8 or Unicode encodings is invalid.

I made changes in the function and fixed the problem.
Please review my code and commit it to the main source.

---------------------------------------------------------------
```
public Range Find(Range r, Regex findExpression, bool searchUp)
{
// Single line and Multi Line in RegExp doesn't really effect
// whether or not a match will include newline characters. This
// means we can't do a line by line search. We have to search
// the entire range because it could potentially match the
// entire range.

string text = r.Text;
Match m = findExpression.Match(text);

if (!m.Success)
return null;

if (searchUp)
{
// Since we can't search backwards with RegExp we
// have to search the entire string and return the
// last match. Not the most efficient way of doing
// things but it works.
Range range = null;
while (m.Success)
{
int start = r.Start + Scintilla.Encoding.GetByteCount( text.Substring( 0, m.Index ) );
int end = Scintilla.Encoding.GetByteCount( text.Substring( m.Index, m.Length ) );

range = new Range(start, start + end, Scintilla);
m = m.NextMatch();
}

return range;
} else {
int start = r.Start + Scintilla.Encoding.GetByteCount( text.Substring( 0, m.Index ) );
int end = Scintilla.Encoding.GetByteCount( text.Substring( m.Index, m.Length ) );

return new Range( start, start + end, Scintilla );
}
}
```
