beet write seems to have no effect

[gcoter]

Problem

Running this command in verbose (-vv) mode:

$ beet -vv write -f

Doesn't seem to actually update my files tag. For instance, in the logs I see this:

Antonio Vivaldi - Die vier Jahreszeiten - Violinkonzerte op.8 : Der Winter I - Allegro non molto
  bpm: 137 -> 137.011138916
Sending event: write
Sending event: after_write
Sending event: database_change

But if I check the bpm in the track and in the library fields:

$ beet info Antonio Vivaldi Der Winter | grep bpm
                 bpm: 137
$ beet info -l Antonio Vivaldi Der Winter | grep bpm
                 bpm: 137.011138916

You can see that they are not the same. I would expect beet write to update my file tags so that they correspond to what is in the database. Here it looks like it doesn't actually write something. Is there something I misunderstood?

Hello! The problem here is one of representations: the on-disk format uses an integer, and beets internally uses a floating-point number. So unfortunately the number must be rounded when writing to the tag.

See also #762.

Hi @sampsyo, thank you for your quick answer! I saw a PR which seems to solve this problem: #3508

However, it looks very recent and it doesn't seem to be included in the last released version of beets. Should I install beets from the master branch?

Seems worth a shot!

It worked! Thanks for your help 🙂
