2- [ ] stats
3 - [ ] download times per peer
4- [ ] Output formats:
5 - [x] text long
6 - [x] text short
7 - [ ] HTML
8 - [ ] JSON
9- [ ] Convert to Typed Racket
10 - requires: build executable (otherwise too slow)
11- [x] Build executable
12 Implies fix of "collection not found" when executing the built executable
13 outside the source directory:
14
15 collection-path: collection not found
16 collection: "tt"
17 in collection directories:

25- [ ] Support redirects
26 - should permanent redirects update the feed somehow?
27- [ ] Support time ranges (i.e. reading the timeline between given time points)
28- [x] Implement rfc3339->epoch
29- [x] Remove dependency on rfc3339-old
30- [x] remove dependency on http-client
31- [ ] optional text wrap
32- [ ] write
33- [x] caching (use cache by default, unless explicitly asked for update)
34 - [x] value --> cache
35 - [x] value <-- cache
36 requires: d command
37- [ ] timeline limits
38- [ ] feed set operations (perhaps better done externally?)
39- [ ] timeline as a result of a query (feed set op + filter expressions)
40- [ ] named timelines
41- [ ] config files
42- [ ] parse "following" from feed
43 - following = <nick> <uri>
44- [x] parse mentions:
45 - [x] @<source.nick source.url>
46 - [x] @<source.url>
47- [ ] highlight mentions
48- [ ] filter on mentions
49- [ ] highlight hashtags
50- [ ] filter on hashtags
51- [ ] hashtags as channels? initial hashtag special?
52- [ ] query language
53- [ ] console logger colors by level ('error)
54- [ ] file logger ('debug)
55- [-] commands:
56 - [x] r | read
57 - see timeline ops above
58 - [ ] w | write
59 - arg or stdin
60 - nick expand to URI
61 - [ ] q | query
62 - see timeline ops above
63 - see hashtag and channels above
64 - [x] d | download
65 - [x] u | upload
66 - calls user-configured command to upload user's own feed file to their server
67 Looks like a better CLI parser than "racket/cmdline": https://docs.racket-lang.org/natural-cli/
68 But it is no longer necessary now that I've figured out how to chain (command-line ..) calls.
69- [ ] Suport immutable timelines
70 - store individual messages
71 - where?
72 - something like DBM or SQLite - faster
73 - filesystem - transparent, easily published - probably best
74 - [ ] block(chain/tree) of twtxts
75 - distributed twtxt.db
76 - each twtxt.txt is a ledger
77 - peers can verify states of ledgers
78 - peers can publish known nick->url mappings
79 - peers can vote on nick->url mappings
80 - we could break time periods into blocks
81 - how to handle the facts that many(most?) twtxt are unseen by peers
82 - longest X wins?
83- [ ] Peer discovery
84 requires:
85 - parse mentions
86 - parse following
87 rough sketch from late 2019:
88
89 let read file =
90 ...
91 let write file peers =
92 ...
93 let fetch peer =
94 (* Fetch could mean either or both of:
95 * - fetch peer's we-are-twtxt.txt
96 * - fetch peer's twtxt.txt and extract mentioned peer URIs
97 * *)
98 ...
99 let test peers =
100 ...
101 let rec discover peers_old =
102 let peers_all =
103 Set.fold peers_old ~init:peers_old ~f:(fun peers p ->
104 match fetch p with
105 | Error _ ->
106 (* TODO: Should p be moved to down set here? *)
107 log_warning ...;
108 peers
109 | Ok peers_fetched ->
110 Set.union peers peers_fetched
111 )
112 in
113 if Set.empty (Set.diff peers_old peers_all) then
114 peers_all
115 else
116 discover peers_all
117 let rec loop interval peers_old =
118 let peers_all = discover peers_old in
119 let (peers_up, peers_down) = test peers_all in
120 write "peers-all.txt" peers_all;
121 write "peers-up.txt" peers_up;
122 write "peers-down.txt" peers_down;
123 sleep interval;
124 loop interval peers_all
125 let () =
126 loop (Sys.argv.(1)) (read "peers-all.txt")
