Wish Simple CharSequence

To Mr Erel,
I wish you add a new command to B4A to get a simple CharSequence, instead of typing a long code using Append & Pop
such as this function:

A simple CharSequence:
'To Make a simple CharSequence:
'Message="Color1/txt1/Color2/txt2/Color3/txt3...."
'  Example : <code>
'Dim msg As string
'msg="black/Hello Mr. /red/Antoine /green/*EGO*/gray/ How are you?"
'Msgbox(CS(msg),"Title")
'  Equals to :
'Dim msg As CSBuilder
'msg.Initialize.Append("Hello Mr. ").Color(Colors.Red).Append("Antoine ").Pop. _
'Color(Colors.Green).Bold.Append("EGO").Pop.Pop.color(Colors.gray).Append _
'(" How are you?").PopAll
'Msgbox(msg,"Title")
'</code>
'If Color is ommitted so it is Black
'If text is written like *txt* so it is Bold
'If text starts with {} so a new line is add, Example:<code>
'Message="red/Dear sir/blue/{}Hope we meet tomorrow./green/{}*Thanks*"
'Message="/Dear sir//{}Hope we meet tomorrow.//*{}Thanks*"
'</code>
Sub CS (Message As String) As CSBuilder
    Dim msg As CSBuilder
    msg.Initialize
    '-------------------
    If Not (Message.Contains("/")) Then
        msg.Append(Message).PopAll
        Return  msg
    End If
    '--------------------
    Dim L,i As Int
    Dim P() As String' Parts of string
    Dim A As String
    
    P=Regex.Split("/",Message)
    L=P.Length 'How many parts
    Log("L="&L)
    Dim C(L) As Int 'Color of the part
    If L Mod 2 <>0 Then L=L-1' If L is odd we ommit the last Part
    
    For i=0 To L-1
        If i Mod 2=0 Then '--------------------
            'even number
            Select P(i).ToLowerCase'same color numbers as DOS
                'Case "black","0","":C(i)=Colors.DarkGray
                Case "blue","1":C(i)=Colors.blue
                Case "green","2":C(i)=Colors.green
                Case "cyan","3":C(i)=Colors.Cyan
                Case "red","4":C(i)=Colors.red
                Case "magenta","5":C(i)=Colors.Magenta
                Case "yellow","6":C(i)=Colors.yellow
                Case "white","7":C(i)=Colors.white
                Case "gray","8":C(i)=Colors.gray
                Case Else
                    C(i)=Colors.DarkGray
            End Select
        Else '--------------------
            'Odd Number
            If p(i).StartsWith("{}") Then 'add a new line
                msg.Append(CRLF)
                P(i)=P(i).SubString(2)
            End If
            
            If p(i).StartsWith("*") And P(i).EndsWith("*") Then ' Bold text must be like: *txt*
                P(i)=P(i).Replace("*","")
                If p(i).StartsWith("{}") Then 'add a new line when text is *{}txt* instead of {}*txt*
                    msg.Append(CRLF)
                    P(i)=P(i).SubString(2)
                End If
                msg.Color(C(i-1)).Bold.Append(P(i)).Pop.Pop
            Else
                msg.Color(C(i-1)).Append(P(i)).Pop
            End If
        End If '--------------------
    Next
    msg.append("").PopAll
    Return msg
End Sub

I wish it would be built-in, as a new command in B4A, so we can use it anytime.
Besides, Mr. Erel can develop the command better than I do.
Using Append & Pop is really tiring when we have many spans.
This command uses (Message As String) so you can anytime have a colored message without turning the message into CSBuilder.

Most of time we don't need more than a colored message!

Hi Antoine

You should have posted it under 'Code Snippets' section of Forum.
Erel do not need to do anything here. We all can use your code to minimize the code for this scenario.
Thanks for it.

Regards,

Anand
