pdsfs - mount an atproto PDS repository as a FUSE filesystem.
2
3
+
a PDS repository[0] contains all data published by a user to
4
+
the atmosphere[1]. it is exportable as a CAR
5
+
(content-addressable archive) file. pdsfs is a tool that
6
+
mounts this CAR file as a readonly-FUSE filesystem, allowing
7
+
quick and easy exploration.
8
9
+
to motivate the need for such a program, we could begin by
10
+
mounting a repository:
11
12
13
+
λ pdsfs oppi.li
14
+
mounted at "mnt"
15
+
hit enter to unmount and exit...
16
+
17
+
18
+
oppi.li is my handle in the atmosphere. the tool does some
19
+
hardwork to determine the location of my PDS repository
20
+
given my handle, but that is not important. lets have a look
21
+
around:
22
+
23
+
24
+
λ ls mnt/
25
+
did:plc:qfpnj4og54vl56wngdriaxug/
26
+
27
+
28
+
the did:plc:stuff is my DID. lets dig deeper:
29
+
30
+
31
+
λ ls mnt/did\:plc\:qfpnj4og54vl56wngdriaxug/
32
+
app.bsky.actor.profile/ place.stream.chat.message/
33
+
app.bsky.actor.status/ place.stream.chat.profile/
34
+
app.bsky.feed.generator/ place.stream.key/
35
+
app.bsky.feed.like/ place.stream.livestream/
36
+
app.bsky.feed.post/ sh.tangled.actor.profile/
37
+
app.bsky.feed.repost/ sh.tangled.feed.reaction/
38
+
app.bsky.graph.block/ sh.tangled.feed.star/
39
+
app.bsky.graph.follow/ sh.tangled.graph.follow/
40
+
app.rocksky.album/ sh.tangled.knot/
41
+
app.rocksky.artist/ sh.tangled.knot.member/
42
+
.
43
+
.
44
+
.
45
+
46
+
47
+
we have some data from the repository now. these are
48
+
"collections". if i want to publish a post to bluesky, i
49
+
would write content to the "app.bsky.feed.post" collection
50
+
in my PDS. this will then be indexed by a bluesky appview
51
+
(bsky.app or zeppelin.social to name a few) and show up
52
+
under my profile there.
53
+
54
+
pdsfs is kind enough to deserialize the data stored (as
55
+
CBOR) in the PDS repository to JSON:
56
+
57
+
58
+
λ cat sh.tangled.repo/3ljidbevrjh22 | jq
59
+
{
60
+
"$type": "sh.tangled.repo",
61
+
"addedAt": "2025-03-03T16:04:13Z",
62
+
"knot": "knot1.tangled.sh",
63
+
"name": "hello-world",
64
+
"owner": "did:plc:3danwc67lo7obz2fmdg6jxcr"
65
+
}
66
+
67
+
68
+
thanks pdsfs!
69
70
+
i publish my music listening habits to my PDS to the
71
+
"app.rocksky.scrobble" collection, because rocksky[4]
72
+
recognizes and indexes this collection. i have wired up my
73
+
personal navidrome instance to write data of this form into
74
+
my PDS everytime i listen to a track. here are my top
75
+
artists in order:
76
77
+
78
+
λ cat app.rocksky.scrobble/* | jq -r '.artist' | sort | uniq -c | sort -nr

all my friends use tangled.sh, which requires them to
139
+
publish their ssh public key to their PDii (PDSes?). perhaps
140
+
i would like to add their keys to my allowed_signers file to
141
+
verify their commit signatures:
142
+
143
+
144
+
λ for dir in ./*/sh.tangled.publicKey;
145
+
do cat $dir/$(ls -r $dir | head -n1) | jq -r '.key';
146
+
done | tee allowed_signers

FUSE is quite liberating in that it allows you to represent
157
+
anything as a filesystem. when applications like ls and cat
158
+
are executed, the system calls to open and read are rerouted
159
+
to your custom fs implementation (pdsfs in this case). the
160
+
custom fs implementation is free to as it pleases, in fact
161
+
the first iteration of pdsfs accessed the network for each
162
+
open/read call to fetch live data from PDii.
