Limit Query Plugin

limit is a plugin to limit a query to the first or last set of results. We also provide a query prefix '<n' to inline the same behavior in the list command. They are analagous to piping results:

$ beet [list|ls] [QUERY] | [head|tail] -n n

There are two provided interfaces:

1. beet lslimit [--head n | --tail n] [QUERY] returns the head or tail of a query

  1. beet [list|ls] [QUERY] '<n' returns the head of a query

There are two differences in behavior:

  1. The query prefix does not support tail.

2. The query prefix could appear anywhere in the query but will only have the same behavior as the lslimit command and piping to head when it appears last.

Performance for the query previx is much worse due to the current singleton-based implementation.

So why does the query prefix exist? Because it composes with any other query-based API or plugin (see Queries). For example, you can use the query prefix in smartplaylist (see Smart Playlist Plugin) to limit the number of tracks in a smart playlist for applications like most played and recently added.

Configuration

Enable the limit plugin in your configuration (see Using Plugins).

Examples

First 10 tracks

$ beet ls | head -n 10 $ beet lslimit –head 10 $ beet ls ‘<10’

Last 10 tracks

$ beet ls | tail -n 10 $ beet lslimit –tail 10

100 mostly recently released tracks

$ beet lslimit –head 100 year- month- day- $ beet ls year- month- day- ‘<100’ $ beet lslimit –tail 100 year+ month+ day+
