Cyr to Lat Enhanced

About this plugin

Questions

How can I define my own substitutions?

You can modify or extend the transliteration table by using the ctl_table filter.

Add this code to your theme’s functions.php file:

function my_cyr_to_lat_table( $ctl_table ) {
    $ctl_table['Ъ'] = 'U';
    $ctl_table['ъ'] = 'u';
    return $ctl_table;
}
add_filter( 'ctl_table', 'my_cyr_to_lat_table' );

How can I adjust the background batch size?

By default, the plugin processes slugs in batches to avoid timeouts.
On slower or low-memory servers, you may want to reduce the batch size.

Add this code to your theme’s functions.php file:

function my_ctl_batch_size( $size, $context ) {
    // Apply the same batch size for posts and terms.
    return 100;
}
add_filter( 'ctl_enhanced_batch_size', 'my_ctl_batch_size', 10, 2 );

Can I modify the generated slugs after transliteration?

Yes. You can adjust the final slug value after transliteration and normalization
by using the ctl_enhanced_sanitized_title filter.

Add this code to your theme’s functions.php file:

function my_ctl_modify_slug( $slug, $source, $context ) {
    // Example: append a suffix to all generated slugs.
    return $slug . '-custom';
}
add_filter( 'ctl_enhanced_sanitized_title', 'my_ctl_modify_slug', 10, 3 );

Can I modify media file names after transliteration?

Yes. You can adjust media file names after transliteration and normalization
by using the ctl_enhanced_sanitized_file_name filter.

Add this code to your theme’s functions.php file:

function my_ctl_modify_filename( $filename, $source ) {
    // Example: prepend a prefix to all media file names.
    return 'media-' . $filename;
}
add_filter( 'ctl_enhanced_sanitized_file_name', 'my_ctl_modify_filename', 10, 2 );

What is the difference between Cyr to Lat Enhanced, cyr2lat and Transliterator?

Cyr to Lat Enhanced is a continuation of the original cyr2lat / cyr3lat lineage.
Its purpose is strictly limited to transliteration of post slugs, term slugs and media file names.

The original cyr2lat plugin by Sergey Biryukov introduced a simple and effective way to generate Latin slugs from Cyrillic titles.
Cyr to Lat Enhanced preserves this philosophy while modernizing the codebase, improving reliability and ensuring compatibility with current WordPress versions.

Transliterator is a separate plugin with a different scope and goals.
It is designed for advanced and complex use cases, including:
– transliteration of post content and front-end text
– bidirectional conversion (Latin and Cyrillic)
– extended language rules and exclusions
– fine-grained control over when and where transliteration is applied

Because these plugins solve different problems, they are intentionally separated.
Cyr to Lat Enhanced focuses on clean URLs and file names with zero configuration.
Transliterator focuses on full-language processing and advanced multilingual setups.

Users should choose the plugin that best matches their needs:
– use Cyr to Lat Enhanced for simple, automatic slug and filename transliteration
– use Transliterator when full content-level transliteration is required
