Title Case

I saw this the other day

--- Code: ---using System;
using System.Collections.Generic;

public static class ClipboardFusionHelper
{
    public static string ProcessText(string text)
    {
        //Words that will not be capitalized; add words to this list as required
        string[] exceptionsArray = { "a", "an", "and", "any", "at", "from", "into", "of", "on", "or", "the", "to", };
     
        List<string> exceptions = new List<string>(exceptionsArray);
     
        //Break the input text into a list of capitalized (not upper case) words
        text = System.Threading.Thread.CurrentThread.CurrentCulture.TextInfo.ToTitleCase(text.ToLower());
        List<string> words = new List<string>(text.Split(new char[] { ' ' }));

        //Always leave the first word capitalized, regardless of what it is
        text = words[0];
        words.RemoveAt(0);
       
        //Check each remaining word against the list, and append it to the new text
        foreach (string s in words)
        {
            if (exceptions.Contains(s.ToLower()))
               text += " " + s.ToLower();   
            else
               text += " " + s;
        }

        return text;
    }
}
--- End code ---

I thought I'd like to translate it to MS & add it to a button.

I can grab & split a filename, I can see how I could use the str selection to alter the words I want in lower case to lower case ... but I'm wondering if I need something like a regex version of
--- Code: ---<str> StrReplace(<str> input, <str> find, <str> with );
--- End code ---

Maybe I just haven't figured out the ordering of commands to modify the arrays yet but I'd really like something that would give me a [a-z] -> [A-Z] function :P

Any advice Mathias?

AlanJB:
Hi Ulf.

Can you not use combinations of StrToUpper() and StrSub()?

Mathias (Author):
I think it should be possible

Would be very similar I think..
Except I do not know what ToTitleCase(..) does ?  You have to recreate that in script I think.
But should not be to hard. String manipulation is supported.. 
And as Alan say.. StrToUpper and StrSub would be something to use..

If you try to write something, then leave a post if you get stuck I might be able to help out

Ulfhednar:
Thanks for the replies.  :)

I am using StrToUpper and StrSub .  The trouble probably is my finding the right approach.

This was a way I'd looked at word capitalization, but a regex gives me all the instances quicker.

--- Code: --- ...
@var $arrN = StrSplit( $NameA, " ");
@var $Words = $arrN[1];
@var $Char1 = StrSub($Words, 0, 1);
@var $arrN1 = StrToUpper($Char1);
...

--- End code ---

Via regex I can have the number of instances output, hence my search for a regex replace function.
Using StrRegExpFind & a simple \s[a-z] gives me all the lower case words, I should in theory be able to take each instance ($1 $2 etc) & handle it with the StrToUpper - but that doesn't seem to be possible (tho it may be just me not getting the <str> &/or <arr> code right!) so I wondered if there might be a StrRegExpReplace function... 
Can I pass the instances found by StrRegExpFind to the StrToUpper  function?  :-\ 

The exception list should be straight forward enough - I can just run them one by one, would be nice if I could pass the exception array as in the C# above tho!   The C# seems to require a lot less steps to achieve the result.

My plan was

* acquire the selected file name(s)
* select the words ignoring 1st word
* all words to lower case
* capitalize all words
* find words in the exception list & make them lower case
* write the new title case string to the filename.
I don't know if I'm misunderstanding you Mathias ref  - ToTitleCase - could just be how the author has labelled the process the code invokes & displays on the GUI as opposed to a specific C# function....?

The idea was to take a title eg
ANT-MAN AND THE WASP  | ant-man and the wasp | Ant-Man And The Wasp
& convert it to Title Case = Ant-Man and the Wasp
(Altho I think in this case it may need to be Ant-Man and The Wasp...  ::) :P)

This process obviously applies to many titles where simply using Camel-Case doesn't look pretty/over-emphasizes secondary prepositions etc.
I liked the idea so thought it might be fun (!) to try to recall how to script with MS   ::)  ;D

Mathias (Author):
Here is a function in MultiScript that does TitleCase. kind of..

--- Code: ---@var $exceptionsArray[] = { "a", "an", "and", "any", "at", "from", "into", "of", "on", "or", "the", "to", };

function TitleCase($name)
{
   return  _TitleCase($name, " ");
}

function _TitleCase($name , $splitchar)
{

  @var $result = "";
  @var $parts = StrSplit($name , $splitchar); // space and - will split string
 
  @var $cnt = arrayCount( $parts );
  for( $n = 0; $n < $cnt ; $n++ )
  {
    @var $textPart = $parts[ $n ];
    // To Lower
    $textPart = StrToLower( $textPart );
 
    if( StrFind( $textPart , "-", 0 ) > 0)
    {
      // Becuse of recursive bug, $n is is overwriten
      $oldN = $n;
      $textPart = _TitleCase($textPart , "-");
      $n = $oldN;
    }

    if( arrayFind( $exceptionsArray, $textPart ) == -1)
    {
    // Uppser case on first
    $textPart[0] = StrToUpper( $textPart[0] );
    }

    if( StrLen( $result ) > 0 )
$result += $splitchar;

    $result += $textPart;
  }
  return $result;
}
@var $newText = TitleCase("ANT-MAN AND THE WASP");

--- End code ---

Hmm Found a bug with calling recusrive ( same function calling it self.)  variables are overwwitten.. so there is a workaround in the code for that..
