Introduce new filter in bp_get_group_description_excerpt() for setting the excerpt_length

[lenasterg]

Setting the length of group description excerpt isn't easy if you want to keep the output format of bp_create_excerpt().
It can be more easier for theme developers, by setting the length using a filter (similar to the bp_activity_excerpt_length filter).

Attached is the suggested filter addition.

New filter bp_group_description_excerpt_length

[boonebgorges]

I'd rather not set a precedent of creating a specific filter for excerpt_length every time we call bp_create_excerpt().

What we can do to make this easier for you is to pass the $group object along to the filter. So then you can do this:

function bbg_custom_group_description_excerpt( $excerpt, $group ) {
    $excerpt = bp_create_excerpt( $group->description, 100 );
}
add_filter( 'bp_get_group_description_length', 'bbg_custom_group_description_excerpt', 10, 2 );

In 7865:

Pass $group object to bp_get_group_description_excerpt filter

This allows theme/plugin authors to more easily customize excerpts.

Fixes #5393

Thanks boonebgorges!

Just a small note to be sure. In your example you mean:

function bbg_custom_group_description_excerpt( $excerpt, $group ) {
    $excerpt = bp_create_excerpt( $group->description, 100 );
    return $excerpt;
}
add_filter( 'bp_get_group_description_excerpt', 'bbg_custom_group_description_excerpt', 10, 2 );

which is working OK with the changes you made in 7865.

P.S.
You are great!!!

Ha, yes, you must return the value. Thanks for pointing it out, and thanks for your contributions!
