Wordpress Xojo syntax highlighter?

I’ve looked at a few from links posted on the forums or found in google but they seem either years old or have broken documentation.

Has anyone got a wordpress xojo syntax highlighter recommendation that they are using at the moment that I can use on my blog without much hacking/tweaking required?

Cheers

Maybe @Thom McGrath can offer something or some help?

this is a subclass of textedit:

this is a needed class:

#tag Class
Protected Class KeyWordGroup
	#tag Property, Flags = &h0
		HighLightColor As color
	#tag EndProperty

	#tag Property, Flags = &h0
		Words() As string
	#tag EndProperty


	#tag ViewBehavior
		#tag ViewProperty
			Name="HighLightColor"
			Group="Behavior"
			InitialValue="&c000000"
			Type="color"
		#tag EndViewProperty
		#tag ViewProperty
			Name="Index"
			Visible=true
			Group="ID"
			InitialValue="-2147483648"
			Type="Integer"
		#tag EndViewProperty
		#tag ViewProperty
			Name="Left"
			Visible=true
			Group="Position"
			InitialValue="0"
			Type="Integer"
		#tag EndViewProperty
		#tag ViewProperty
			Name="Name"
			Visible=true
			Group="ID"
			Type="String"
		#tag EndViewProperty
		#tag ViewProperty
			Name="Super"
			Visible=true
			Group="ID"
			Type="String"
		#tag EndViewProperty
		#tag ViewProperty
			Name="Top"
			Visible=true
			Group="Position"
			InitialValue="0"
			Type="Integer"
		#tag EndViewProperty
	#tag EndViewBehavior
End Class
#tag EndClass

to use it, make a new keywordgroup in the open event of the textedit subclass, choose the colors and the words to colorize.

Dim orange As New KeyWordGroup
orange.HighlightColor=&cFF800000
orange.Words = (get array of strings with the words to color in orange)
Dim red As New KeyWordGroup
red.HighlightColor=&cFF000000
red.Words = (get array of strings with the words to color in red)
...
Me.KeyWordGroups=Array(orange,red)
Me.UpdateHighlighting

and in the textchange event :

Me.UpdateHighlighting

don’t remember where I found this snippet, may be an old RB code ?
but it works nice for my sql editor.

I don’t write Wordpress plugins, but the syntax highlighter php code is available on GitHub. Wordpress uses php, so in theory, it could be adapted without much work.

Actually that reminds me, I got a request to add some keywords to the class a while back which I totally forgot about.

Edit: Here’s the link: https://github.com/thommcgrath/XojoSyntaxColorizer

I’m using RBCode from Gary Pettit on BKeeney Briefs. Works fine on the most current version of WordPress https://wordpress.org/plugins/rbcode/

Thanks all! I went with Bob’s recommendation and tweaked it a little so line numbers aren’t copied. Thanks Gary if you stumble across this post.
