Add Support for Telde Format Char to Trim

In the Firefly Project

WizardOfOz.Witch.Types.TextFormat Class

1. Add the following two members:

public static char CharToIndicateTrim = '~';
bool _trimResult = false; 

2. Add the following chars to the constructor:

ImeMode _imeMode = ImeMode.NoControl;
TextFormat(string format)
{
    if (string.IsNullOrEmpty(format))
    {
        _ignoreFormat = true;
        _dataLength = int.MaxValue;

        return;
    }
    if (format.Length == 1 && format[0] == CharToIndicateTrim)
    {
        _ignoreFormat = true;
        _dataLength = int.MaxValue;
        _trimResult = true;
        return;
    }

    FormatStructure<TextFormatHelper> structure = new FormatStructure<TextFormatHelper>();
    _formater = new StructureBridgeToFormater(structure);
    bool hassimpleSingleItem = false;
    FormatReader fr = new FormatReader(format); 

3. Later in that constructor add the following code to the default part of the switch statement that starts on line 150 in our version of the code:

case 'H':
    _hebrew = true;
    break;
case 'K':
    if (char.IsNumber(fr.PeekChar()))
    {
        var x = fr.ReadNumber();
        _imeMode = TranslateImeMode(x);
        break;
    }
    else
        goto default;
default:
    if (c == CharToIndicateTrim)
    {
        _trimResult = true;
    }
    else
    {
        structure.AddConstant(c, fr.ReadNumber());
        _hasNoConstants = false;
    }
    break; 

4. Replace the ToText method which receive two parameters implementation

public Text ToText(Text source, TextFormatHelper helper)
{
-   if (_ignoreFormat)
-       return source;
-   return _formater.ToText(source, helper);
    var result = source;
    if (!_ignoreFormat)
    {
        result = _formater.ToText(source, helper);
    }
    if (_trimResult && result != null)
        result = result.Trim();
    return result;
} 

WizardOfOz.Witch.Types.NumericFormatClass

1. Add the following member to the class

bool _autoSkip = false;
bool _allowNegative = false;
bool _commaSeperated = false;
bool _leftJustified = false;
bool _trim = false;
char _fillerChar = ' ';
char _zeroValueFillerChar = (char)0; 

2. in the constructor add the following code to the default part of the switch statement that starts on line 117 in our version of the code:

switch (c)
{
    case 'L':
        _leftJustified = true;
        break;
    case 'A':
        _autoSkip = true;
        break;
    case 'N':
        _allowNegative = true;
        break;
    case 'C':
        _commaSeperated = true;
        break;
    default:
        if (c == TextFormat.CharToIndicateTrim)
        {
            _trim = true;
            break;
        }
        else
            return false;
} 

3. In the ToStringClass Constructor add at the end:

    ...
    PrepareOriginalNumber();

    if (_fillerChar != (char)0) Result = "".PadLeft(Result.Length, _fillerChar);
    if (_parent._trim)
        Result = Result.Trim();
} 

Firefly.Box.Data.Advanced.TypedColumnBase class

Add the following code to the GetDisplayTextProvider method

internal DisplayTextProvider<dataType> GetDisplayTextProvider(string format, bool useInputRange)
{
    if (string.IsNullOrEmpty(format))
        format = _formatString;
    if (format!=null&& format.Length == 1 && format[0] == TextFormat.CharToIndicateTrim)
        format = _formatString + format;
    if (_prevDisplayTextProvider == null || !(_lastFormat == format && _lastUseInputRange == useInputRange))
    {
        _prevDisplayTextProvider = _CreateDisplayTextProvider(format, useInputRange ? _range : string.Empty, _nullDisplayText ?? string.Empty);
        _lastFormat = format;
        _lastUseInputRange = useInputRange;
    }
    return _prevDisplayTextProvider;

             
}
