MPC_FORMAT and mpc ls | mpc add

[nmeum]

I would like to change the format used by mpc to also include the '%position%' format specifier when performing mpc playlist in order to be able to use mpc play <position>. This can be achieved by setting the MPC_FORMAT environment variable to something along the lines %position%: [[[%artist% - ]&[%title%]]|[%file%]].

Unfortunately, doing so breaks the mpc ls | mpc add combination as mpc ls will also pickup this format. If MPC_FORMAT is unset a different default format seems to be used for mpc playlist and mpc ls.

I would suggest one of the following solutions:

1. Always ignoring MPC_FORMAT in mpc ls
2. Allowing the specification of custom format string on a per-subcommand basis (e.g. MPC_FORMAT_LS, MPC_FORMAT_PLAYLIST, MPC_FORMAT_CUR, …)
3. Making mpc ls default to format %file% when standard out is not a tty.

mpc ls|mpc add is not a supported use case. There is never a good reason to do that.

Ok I get it. mpc ls|mpc add can simply be replaced by mpc add / but what about mpc search artist foo | mpc add?
