Are there any plans to include support for Visual Studio 2005's 'Code Snippet' Technology within SyntaxEditor?

Yes, that is on our TODO list. Thanks for the suggestion though!

Derek,
If you don't want to wait until the feature is implemented, the latest release of Syntax Editor includes all the features you need to implement this on your own. The KeyTyping event can be used to trap the 'tab' key used to expand and CodeSnippet, and custom SpanIndicators can be used to mark the individual fields.

The KeyTyping event can be used to trap the 'tab' key used to expand and CodeSnippet, and custom SpanIndicators can be used to mark the individual fields.
I don't understand. I'm not sure how the SpanIndicator could help me ..I'd need to create a field with a visual border and stuff and make it tabbable ...which doesn't seem possible. I cannot find any useful documentation on the SpanIndicator class either other than the member list, which is useless.
You create a custom SpanIndicator class that is used to draw the highlighted background and border. You'll have to handle tab navigation yourself by trapping the Tab key in the KeyTyping event.
You'll need Three SpanIndicators to copy VS 2005:
1) Active Field with colored background and black border
2) Non-active Field with colored background and no border
3) Secondary instances of Active Field with no background and dashed border
Within the KeyTyping event, you'll need to determine if you're currently inside one of your SpanIndicators. If so, you need to cancel the Tab key operation and move the caret to the next SpanIndicator for an active field. You'll also need to trap the Esc key to cancel the CodeSnippet mode.
This process wasn't easy to implement (took me about 12 hours to design and test), but does work. If you're new to SyntaxEditor, you may want to wait on this feature until you're more familiar with the tool (or until it's part of the SyntaxEditor product).

Alright. I'm still confused on how to user the SpanIndicator. Is there a sample or tutorial of it somewhere that I can look at to get a feel for how it works?
It's an abstract class, so I've tried inheriting it and it still doesn't like to work. I cannot find any sample usage code of it anywhere, so I'm really stumped.

There are some samples on span indicator implementation in this forum. Use the forum search to find them.
The sample app shows how to instantiate some pre-packaged ones like when you click in the indicator margin.

I'll keep trying ..but the documentation for it is still pretty poor. I think it could really use some actual documentation in the future. A lot of SyntaxEditor has very weak documentation that makes it very hard to get into..
There doesn't seem to be a way to give a border color to the HighlightingStyle method of SpanIndicator. Any suggestions? So far I've got an Inherited SpanIndicator that just highlights the right portion of code. =/
Right for that you'd have to override the DrawMarks method and just draw a rectangle around the bounds.

Yeah, that's what I'm trying ...this is what I've got, but it doesn't seem to do the trick.

Alright, making some progress. The Constructor needed the following..
IndicatorMarks.Adornments;
However the problem is that the bounds are too big. Let me try some deflating and stuff.. I'm still not sure if this will work right, but I hope it will.
Hrnm. Well, leaving the bounds at the default size doesn't work. The bottom line is cut off. The rectangle area simply isn't big enough. Any suggestions there?
Nevermind. I got it. I just had to pass each parameter of the rectangle. I was thinking it would be more complex than that. Alright, this should get me started. Thanks a lot for your help, I'll keep trying and post back if I have any more big problems.

Yes this is what I consider to be a longstanding bug with GDI. The bounds we pass are the correct bounds. If you call Graphics.FillRectangle and pass the bounds, they fill correctly. However if you call Graphics.DrawRectangle and pass the bounds, it draws the left/top lines correctly but moves the right/bottom lines out one pixel. I have no idea why Microsoft implemented things that way.
So we always end up doing what you found and doing something like:It's silly that that is necessary but that's how Microsoft chose to make things work.
So we always end up doing what you found and doing something like:
g.DrawRectangle(bounds.Left, bounds.Top, bounds.Width - 1, bounds.Height - 1);Actipro Software Support
So can I enforce an Indicator on text that is not selected? Ideally, I'd like to be able to 'expand' a segment of code and then tell it what to highlight. Is that possible?
You should probably override this property... By default it is false. You probably want it true for your situation.

protected internal virtual bool ExpandOnBoundaries {
get {
return false;
}
}Actipro Software Support
Woah, yeah. Thanks. That will help a lot.
Alright. This is what I've got so far. I've got three different methods for the "Trigger" event. -.- -- I've got it to do the highlighting, but I'm still very confused about how the Tokens work. I want it to not re-highlight something if the $ is deleted and then re-added, and I want it to track it properly...

I'm sorry... not really following what you are trying to accomplish. Can you summarize?
Actipro Software Support
Certainly ---
Just a review of how the snippets work to make sure we're on the same page -- forgive me if this is moot.
I've got a class called "CodeSnippetDeclaration", which represents a literal declaration within a code snippet. The object of a declaration is that it is a variable that, when the snippet is pasted, the cursor is placed within and you can tab between the various declarations. Declarations are defined with a $[A-Z]$ syntax.
Declarations is a Generic Collection List<CodeSnippetDeclaration>.
What I am trying to do is, in the 'code' view, when a user types a "$" symbol, it will populate the intellisense window with a list of the current declarations for the code snippet (this is a code snippet DESIGNER tool). Which I have semi-successfully done in the code above, as you can see. I'm not really happy with it, but it works okay.
When they select one of the valid declarations, and end it with a "$", it will encapsulate that declaration in a HighlightingIndicator.
My problem is this -- it does do the above functionality, but it has many bugs
1. It cannot seem to highlight the declaration if the first "$" is the first character on a line
2. HighlightIndicators can easily 'overlap' each other. If the user tries it. For instance
$literal$$literal, while not what the user would want to type in, is still valid text, and
if inputted, it screws up the highlighting. I want to try and safeguard against this.
3. When I open a snippet from a file, I want the highlighting to resume, so I need to be able
to iterate the document and find all of the declarations and highlight them.

Question... instead of using span indicators to highlight declarations, can you just make a lexical pattern with the custom highlighting within the XML language definition itself? That way the lexical parser will identify tokens that are declarations for you.
Actipro Software Support
But I need the window to be in the C# or VB.NET language, so a lexical pattern wouldn't work. I can't seperate things with the <script> tag like in the examples either. I'm not sure how one would go about that. Furthermore, I need to be able to tab between the different highlighted fields.
This is what I'm trying, but it's not working. I've been looking at the Regular Expressions Documentation and it isn't helping much ...I'm still very confused.just using the lexical parser -- I just want to highlight things between $ and $. How can this be accomplished? It isn't seeming to respond to anything I put in for "PatternValue".

Well $ is a reserved character so as the documentation says, you can escape reseved regex characters by putting a backslash before them like: \$
I've seen Boyd's implementation of snippets and he intercepts the KeyTyping event so that when snippets are active, instead of allowing characters to be typed, he starts an undo group and uses Document.UndoableInsert to insert the typed character in any indicator for the declaration that the selection is currently in. He also is using span indicators to track the declarations and highlight them.
For finding other instances of declarations when you open a file, use the regular expression find capabilities in the Document.FindReplace object model.

I'm sorry, but the \$ doesn't work.
<RegexPatternGroup TokenKey="DeclarationToken" Style="HighlightIndicatorStyle" PatternValue="@? \$(_ | {AlphaMacro})({WordMacro})*\$" />
is my syntax. Replacing the \$ with & works fine using & and &, but when I use \$, it does not work at all.

is my syntax. Replacing the \$ with & works fine using & and &, but when I use \$, it does not work at all.
I pasted your exact line in the C# sample language def at the beginning of the DefaultState pattern groups and changed the highlighting style to one of the styles defined above (since yours wasn't defined in our C# def). When I type $a$ in the document, it highlights as expected.
Actipro Software Support
Can you provide an idea as to when we should see snippets? We were going to code it ourselves but it would be nice to have it supported directly instead.
Not sure, but I would imagine it would be one of the next major features to be implemented since we have a clearer idea of how it should work.
