Custom post type permalink structure with hyphen instead of slash

custom-cpt-permalink-rewrite.php

<?php

// Add filter for creating a custom post link
add_filter( 'post_type_link', 'nstrm_changepost_link_slug', 10, 3 );
function nstrm_changepost_link_slug( $post_link, $post, $leavename ) {

	if ( 'post-type-name' != $post->post_type || 'publish' != $post->post_status ) {
		return $post_link;
	}

	$post_link = str_replace( '/text-/', '/text-', $post_link );

	return $post_link;
}

// Custom rewrite to use the custom post link
add_action( 'generate_rewrite_rules', 'nstrm_add_rewrite_rules' );
function nstrm_add_rewrite_rules($wp_rewrite) {

	$cpt_rule  = array(
		'text-(.+)?' => 'index.php?post_type=post-type-name&post-type-name=' . $wp_rewrite->preg_index( 1 ),
	);
	$wp_rewrite->rules = $cpt_rule + $wp_rewrite->rules;
}
?>

Ah good addition, thanks!

Didn't test it, but i like the add_rewrite_rule function for custom rewrite rules:
https://developer.wordpress.org/reference/functions/add_rewrite_rule/

<?php

add_action( 'init', function() {
	add_rewrite_rule(
		'text-(.+)?',
		array(
			'post_type'      => 'post-type-name',
			'post-type-name' => '$matches[1]',
		),
		'top'
	);
} );
