Sample

B4X:
Sub Process_Globals
    'These global variables will be declared once when the application starts.
    'These variables can be accessed from all modules.
    Dim linker As Linker
End Sub

Sub Globals
    'These global variables will be redeclared each time the activity is created.
    'These variables can only be accessed from this module.
    Dim tv As Label
End Sub

Sub Activity_Create(FirstTime As Boolean)
    'Do not forget to load the layout file created with the visual designer. For example:
    'Activity.LoadLayout("Layout1")
    tv.Initialize("tv")
    Activity.AddView(tv,0,0,100%x,100%y)
    tv.Text= "This is a text for test purpose only , you can't use it in commercial projects without permission"
    linker.Initialize("linker",tv)
    linker.addStrings(Array As String("only","permission"))
    Dim prof As LinkProfile
    prof.Initialize("purpose",Colors.Red,False)
    linker.addProfiles(Array As LinkProfile(prof))

Hi @somed3v3loper and thank you for this library.
But why this new library if in CSBuilder you have already this:


B4X:
Sub Activity_Create(FirstTime As Boolean)
   Activity.LoadLayout("1")
   Dim cs As CSBuilder
   cs.Initialize.Size(30).Append("Some ").Append(CreateClickableWord("words"))
   cs.Append(" are ").Append(CreateClickableWord("clickable")).Append(".").PopAll
   Label1.Text = cs
   cs.EnableClickEvents(Label1)
End Sub

Sub CreateClickableWord(Text As String) As CSBuilder
   Dim cs As CSBuilder
   Return cs.Initialize.Underline.Color(0xFF00D0FF).Clickable("word", Text).Append(Text).PopAll
End Sub

Sub Word_Click (Tag As Object)
   Log($"You have clicked on word: ${Tag}"$)
End Sub

I may well be missing something here but I believe the difference is that this new library can handle existing text and does not need to create it.
