Lexem with Regular Expressions

[Marty Honea]

I'm having a hard time getting Lexems to work with Regular Expressions.

 

I am trying to color code a formula. I need to be able to color code tokens even if they aren't surrounded by a blank space.

 

In the following Formula, How do I write the lexem to set the color of the tokens Inv StartToEcl and Prior?

 

if ( CurrentDate = CaseStart,
    Abandonment[Inv,StartToECL],
    AbdnCurrentDol[Prior]
)

 

I'm able to color CurrentDate, as it has white space on either side of it. CaseStart, isn't found though.

 

if I use \W or \w or \b, I get the entire line color coded. I only want the token itself colored. How can I accomplish this?

 

lx.Add(new Lexem
                {
                    StartText = @"\WPrior\W",
                    IsRegex = true,
                    ContainsEndText = false,
                    IsMultiline = false,
                    LexemType = EditTokenType.Keyword,
                    FormatName = "KeywordFormat"
                });

Ok, I've found the Regular Expression that should work.

 

According to this link

http://help.syncfusion.com/ug/windows%20forms/edit/default.htm#!documents/4251languageelements.htm

 

Lookbacks and Lookforwards are what I was missing.

 

So I created the Regex (?<=\W)Inv+(?=\W)|Inv

This works, in a way. It finds Inv in the formula. But it also highlights the entire row instead of just the match I'm looking for.

 

How can I make it only highlight the match?

For anyone else who's searching this forum with this issue, I've created an Incident with SyncFusion and gotten confirmation that this is indeed broken. They'll be correcting it in a future release.
