Formatters

Formatters are used to output dataset content in specific formats. The AnyDataset-Text package provides two formatters:

  • CSVFormatter - Outputs the content as a CSV file (field delimited)
  • FixedSizeColumnFormatter - Outputs the content with columns defined by length

CSVFormatter​

The CSVFormatter class allows you to output dataset content as a CSV file with customizable delimiter, quote character, and quoting behavior.

Basic Usage​

Using CSVFormatter
<?php
$iterator = $anydataset->getIterator();
$formatter = new \ByJG\AnyDataset\Text\Formatter\CSVFormatter($iterator);
$csvContent = $formatter->toText();

Customization Options​

$formatter = new \ByJG\AnyDataset\Text\Formatter\CSVFormatter($iterator);

// Set the delimiter character (default: ,)
$formatter->setDelimiter(';');

// Set the quote character (default: ")
$formatter->setQuote("'");

// Set the quoting behavior
$formatter->setApplyQuote(\ByJG\AnyDataset\Text\Formatter\CSVFormatter::APPLY_QUOTE_ALWAYS);

// Control whether to output header row (default: true)
$formatter->setOutputHeader(false);

// Get the formatted text
$csvContent = $formatter->toText();

Quoting Behaviors​

The CSVFormatter supports several quoting behaviors:

  • CSVFormatter::APPLY_QUOTE_ALWAYS - Apply quotes to all fields
  • CSVFormatter::APPLY_QUOTE_WHEN_REQUIRED - Apply quotes only when required (default)
  • CSVFormatter::APPLY_QUOTE_ALL_STRINGS - Apply quotes to all string fields
  • CSVFormatter::NEVER_APPLY_QUOTE - Never apply quotes

FixedSizeColumnFormatter​

The FixedSizeColumnFormatter class allows you to output dataset content with fixed-width columns based on field definitions.

Basic Usage​

Using FixedSizeColumnFormatter
<?php
$fieldDefinition = [
    new \ByJG\AnyDataset\Text\Definition\FixedTextDefinition('id', 0, 3, \ByJG\AnyDataset\Text\Definition\TextTypeEnum::NUMBER),
    new \ByJG\AnyDataset\Text\Definition\FixedTextDefinition('name', 3, 7, \ByJG\AnyDataset\Text\Definition\TextTypeEnum::STRING),
    // ... more field definitions
];

$iterator = $anydataset->getIterator();
$formatter = new \ByJG\AnyDataset\Text\Formatter\FixedSizeColumnFormatter($iterator, $fieldDefinition);
$formattedContent = $formatter->toText();

Customization Options​

$formatter = new \ByJG\AnyDataset\Text\Formatter\FixedSizeColumnFormatter($iterator, $fieldDefinition);

// Set the padding character for number fields (default: 0)
$formatter->setPadNumber('0');

// Set the padding character for string fields (default: space)
$formatter->setPadString(' ');

// Get the formatted text
$formattedContent = $formatter->toText();
