Named arguments

This applies to certain APIs, such as mp.command_native() (with tables that have string keys) in Lua scripting, or mpv_command_node() (with MPV_FORMAT_NODE_MAP) in the C libmpv client API.

The name of the command is provided with a name string field. The name of each command is defined in each command description in the List of Input Commands. --input-cmdlist also lists them. See the subprocess command for an example.

Some commands do not support named arguments (e.g. run command). You need to use APIs that pass arguments as arrays.

Named arguments are not supported in the "flat" input.conf syntax, which means you cannot use them for key bindings in input.conf at all.

Property expansion is disabled by default for these APIs. This can be changed with the expand-properties prefix. See Input Command Prefixes.
