This plugin will convert #hashtags references to a link (activity search page) posted within the activity stream

== Description ==

This plugin will convert #hashtags references to a link (activity search page) posted within the activity stream

Works on the same filters as the @atusername mention filter (see Extra Configuration if you want to enable this on blog/comments activity) - this will convert anything with a leading #

Warning: This plugin converts #hashtags prior to database insert/update. Uninstalling this plugin will not remove #hashtags links from the activity content.

Please note: accepted pattern is: `[#]([_0-9a-zA-Z-]+)` - all linked hashtags will have a css a.hashtag - currently does not support unicode.


= Also works with =
* BuddyPress Edit Activity Stream plugin 0.3.0 or greater

== Installation ==

1. Upload the full directory into your wp-content/plugins directory
2. Activate the plugin at the plugin administration page

== Frequently Asked Questions ==

= What pattern is matched? =

The regex looks for /[#]([_0-9a-zA-Z-]+)/ within the content and will proceed to replace anything matching /(^|\s|\b)#myhashtag/

= Can this be enabled with other content? =

Possible - try applying the filter `bp_activity_hashtags_filter`

See extra configuration

= Why convert #hashtags into links before the database save? =

The trick with activity search_terms (which is used for @atmentions) is the ending </a> since BuddyPress's sql for searching is %%term%% so #child would match #children

= What url is used? =

`$bp->root_domain . "/" . $bp->activity->slug . "/". BP_ACTIVITY_HASHTAGS_SLUG ."/myhashtag`

Where you may define the slug in your wp-config.php:

`define( 'BP_ACTIVITY_HASHTAGS_SLUG', 'tag' )`
