command_cond

A simple mpv script that help you run different commands under different conditions.

This script can be used to enhance the input.conf, and can also be used with InputEvent.

Inspired by InputEvent, and using a lot of its code.

Installation

1. Put command_cond.lua into ~~/scripts
2. OPTIONAL: Set the configuration files location in ~~/script-opts/command_cond.conf file

   configs=~~/input.conf
   

3. Configure the commands to be run by the script, synax is just like input.conf but note the run condition in the comment.See configuration for more detail.

Options

configs=~~/input.conf,~~/script-opts/xxxx.conf

The setting in ~~/script-opts/command_cond.conf is used to specify where the script reads conditions and commands from.

Default value is ~~/input.conf, but it is recommended using a separate file for the configuration.

Configuration

synax

<event_name> <command> #|[cond]

The event_name is the name of an event, it is a word without spaces and you can name it whatever you want.

Note: event_name is case-sensitive

The cond is a conditional statement with the same syntax as the profile-cond in Conditional auto profiles in mpv.

The command will be run only when the conditions are met.If cond is blank, it means the command will be executed unconditionally

Priority

When an event is triggered, the script runs the first command in that event that satisfies the condition, checking whether the condition is satisfied in the order from top to bottom in the configuration file.

Commands

This command will trigger the an event with the name event_name:

script-message-to command_cond <event_name>

Example

Jump to the next file at the end of the file

In the default setting of mpv, hitting the right arrow key → will seek forward 5 seconds.When at the end of the file, I want to hit → to play the next file.

1. in command_cond configuration file:

   next playlist-next #|pause and time_remaining < 10
   next seek 5        #|
   

2. in input.conf:

   RIGHT script-message-to command_cond next
   

When pressing the right arrow key, the script will first check if the conditions of the first command are met. The condition for the first command is that the player is paused and the remaining playback time of the file is less than 10 seconds.

When at the end of the file and paused, the condition of the first command is satisfied, so the first command playlist-next is run, and mpv jump to next file.

When not in the above state, the condition of the first command is not met and the script checks the condition of the next command. The condition of the second command is blank, then it is run unconditionally, so the second command seek 5 is executed.
