As it says in the title, I'm looking for multiple excerpt lengths in WordPress.
I understand you can do this in functions.php:
function twentyten_excerpt_length( $length )
add_filter( 'excerpt_length', 'twentyten_excerpt_length' );
What I want to know is how you can have multiple of these each returning different numerical values so I can get short excerpts for sidebar loops, longer excerpts for featured loops, and the longest excerpt for the main article.
Something like using these in the templates:
<?php the_excerpt('length-short') ?>
<?php the_excerpt('length-medium') ?>
<?php the_excerpt('length-long') ?>
