3 a9fc4552 2022-02-17 op amused is a music player. It doesn't have any amazing functionalities
4 213aea73 2022-02-17 op built-in, on the contrary: it's quite minimal (a fancy word to say that
5 213aea73 2022-02-17 op does very little.) It composes well, or aims to do so, with other tools
6 213aea73 2022-02-17 op thought.
7 a9fc4552 2022-02-17 op
8 bbf64a33 2022-02-17 op The main feature is that audio decoding runs in a sandboxed process
9 bbf64a33 2022-02-17 op under `pledge("stdio recvfd audio")`. Oh, by the way, amused targets
10 213aea73 2022-02-17 op OpenBSD only: it relies its make infrastructure to build, uses various
11 213aea73 2022-02-17 op cool stuff from its libc and can output only to sndio.
12 a9fc4552 2022-02-17 op
13 213aea73 2022-02-17 op (I *think* it's possible to compile it on other UNIX-like systems too by
14 213aea73 2022-02-17 op providing shims for some non-portable functions -- hello libbsd -- and
15 213aea73 2022-02-17 op assuming that sndio is available. And that you bundle a copy of imsg.c
16 213aea73 2022-02-17 op too)

19 a9fc4552 2022-02-17 op ## building
20 a9fc4552 2022-02-17 op
21 59b6f826 2022-02-17 op $ make
22 a9fc4552 2022-02-17 op
23 a9fc4552 2022-02-17 op it needs the following packages from ports:
24 a9fc4552 2022-02-17 op
25 a9fc4552 2022-02-17 op - flac
26 0ea0da1e 2022-02-23 op - libmpg123
27 a9fc4552 2022-02-17 op - libvorbis
28 a9fc4552 2022-02-17 op - opusfile
29 a9fc4552 2022-02-17 op
30 a9fc4552 2022-02-17 op Release tarballs installs into `/usr/local/`, git checkouts installs
31 a9fc4552 2022-02-17 op into `~/bin` (idea and implementation stolen from got, thanks stsp!)
32 a9fc4552 2022-02-17 op
33 a9fc4552 2022-02-17 op
34 a9fc4552 2022-02-17 op ## usage
35 a9fc4552 2022-02-17 op
36 a9fc4552 2022-02-17 op The fine man page has all nitty gritty details, but the TL;DR is
37 a9fc4552 2022-02-17 op
38 a9fc4552 2022-02-17 op - enqueue music with `amused add files...`
39 a9fc4552 2022-02-17 op - control the playback with `amused play|pause|toggle|stop` etc
40 a9fc4552 2022-02-17 op
41 213aea73 2022-02-17 op amused tries to be usable in composition with other more familiar tools
42 213aea73 2022-02-17 op instead of providing everything itself. For instance, there isn't a
43 213aea73 2022-02-17 op command to remove an item from the playlist, or shuffle it; instead,
44 213aea73 2022-02-17 op standard UNIX tools can be used:
45 a9fc4552 2022-02-17 op
46 da045d77 2022-02-17 op $ amused show | grep -vi kobayashi | amused load
47 da045d77 2022-02-17 op $ amused show | sort -R | amused load
48 da045d77 2022-02-17 op $ amused show | sort | uniq | amused load
49 da045d77 2022-02-17 op
50 da045d77 2022-02-17 op It also doesn't provide any means to manage a music collection. It
51 da045d77 2022-02-17 op plays nice with find(1) however:
52 da045d77 2022-02-17 op
53 a9fc4552 2022-02-17 op find . -type f -iname \*.opus -exec amused add {} +
54 a9fc4552 2022-02-17 op
55 ee6b8af7 2022-02-17 op Well, for these kinds of things I wrote a wrapper around find called
56 da045d77 2022-02-17 op walk that provides 80% of what I do with find in 20% of the characters:
57 a9fc4552 2022-02-17 op
58 da045d77 2022-02-17 op walk \*.opus amused add
59 a9fc4552 2022-02-17 op
60 213aea73 2022-02-17 op but you got the idea (walk lives in my
