This is similar to the question posed at http://ww.wp.xz.cn/support/topic/plugin-docs-to-wordpress-id-love-to-use-this-for-pages-rather-than-posts and the answer is the same, with a slight twist.
You can extend the Docs to WordPress plugin using the pre_docs_to_wp_insert filter. The plugin would look like this:
<?php
/*
Plugin Name: Docs to WP auto publish
*/
add_filter( 'pre_docs_to_wp_insert', 'docs_to_wp_auto_publish' );
function docs_to_wp_auto_publish( $post_array = array() ) {
$post_array[ 'post_status' ] = 'publish';
return $post_array;
}
I haven’t tested this, but it should do the trick.
