## Overview
6
+
OCaml Matrix SDK providing protocol types and a full HTTP client for the Matrix chat protocol. Uses `requests` for HTTP and `jsont` for JSON encoding/decoding. Also provides an Eio-idiomatic wrapper for structured concurrency.
7
+
8
+
## Current State
9
+
10
+
### matrix_proto Library
11
+
Complete protocol types with jsont codecs and roundtrip tests:
12
+
- `Matrix_id` - User, Room, Event, Device, and Server identifiers with validation
13
+
- `Matrix_event` - Room state and message events with content types
14
+
- `Matrix_sync` - Sync API response types
15
+
16
+

### matrix_eio Library (NEW)
45
+
Eio-idiomatic wrapper providing:
46
+
- **Structured Concurrency**: All operations respect Eio switches for resource cleanup and cancellation
47
+
- **Exception-based Errors**: Operations raise `Eio.Io` exceptions instead of returning Results
48
+
- **Fibre-based Sync**: Sync loop runs in dedicated fibres with proper cancellation support
49
+
- **Eio.Stream Integration**: Push sync events to streams for decoupled event processing
50
+
51
+
Example usage:
52
+
```ocaml
53
+
Eio_main.run (fun env ->
54
+
Eio.Switch.run (fun sw ->
55
+
(* Create and login *)
56
+
let client = Matrix_eio.login_password ~sw ~env
57
+
~homeserver:(Uri.of_string "https://matrix.org")
58
+
~user:"username" ~password:"password" () in
59
+
60
+
(* Send a message *)
61
+
Matrix_eio.Messages.send_text client
62
+
~room_id:(Matrix_proto.Id.Room_id.of_string_exn "!room:server")
63
+
~body:"Hello, Matrix!" ();
64
+
65
+
(* Sync with callbacks *)
66
+
Matrix_eio.Sync.sync_forever ~sw ~clock:(Eio.Stdenv.clock env)
67
+
client
68
+
~on_sync:(fun response ->
69
+
(* Handle sync response *)
70
+
Matrix_eio.Sync.Continue)
71
+
()
72
+
))
73
+
```
74
+
75
+
## Dependencies
76
+
- `jsont` / `jsont.bytesrw` - JSON encoding/decoding
77
+
- `requests` - HTTP client (not cohttp)
78
+

79
+
- `uri` - URI handling

+
- `base64` - Base64 encoding
82
+
- `mirage-crypto` - AES-CBC encryption
83
+
- `mirage-crypto-ec` - Ed25519/X25519 cryptography
84
+
- `mirage-crypto-rng` - Secure random number generation
85
+
- `digestif` - SHA-256 hashing
86
+

87
+
88
+
## TODO
89
+
90
+
### Remaining Features
91
+
- [ ] Integration tests against real homeserver
92
+
- [ ] Secret storage (m.secret_storage.v1)
93
+
- [ ] SQLite/persistent storage implementations (currently in-memory only)
94
+
- [ ] To-device message handling for verification flows
95
+
- [ ] Actual backup upload/download API integration
96
+
- [ ] Send queue HTTP integration (currently provides queue logic only)
97
+
98
+
### Known Limitations & Shortcuts
99
+
100
+
**Verification module:**
101
+
- SAS emoji table has 20 entries (spec requires 64) - needs completion
102
+
- `verify_cross_signing_signature` checks signature existence but doesn't cryptographically verify
103
+
- QR code verification has data structures but no encoding/decoding
104
+
- No to-device message sending for verification protocol flow
105
+
106
+
**Backup module:**
107
+
- Recovery key uses base64 encoding instead of proper base58 (marked in code)
108
+
- `parse_recovered_key` is a stub - needs JSON field extraction
109
+
- Provides encryption/decryption primitives but no server API calls
110
+
- Key backup upload/download requires integration with Client module
111
+
112
+
**Send_queue module:**
113
+
- Provides queue management but no HTTP sending integration
114
+
- Caller must implement `send_fn` to actually send requests
115
+
- Persistence helpers provided but no automatic persistence
116
+
117
+
**Store module:**
118
+
- All three stores (STATE_STORE, CRYPTO_STORE, EVENT_CACHE_STORE) are in-memory only
119
+
- Module types defined for pluggable backends but only memory implementations exist
120
+
- No SQLite or file-based implementations
121
+
122
+
**Timeline module:**
123
+
- LinkedChunk `push_back` has TODO for trimming when over `max_events` limit
124
+
- LRU eviction in Cache removes oldest room but doesn't preserve by access time
125
+
126
+
**Olm module:**
127
+
- Session pickle/unpickle uses simplified JSON format
128
+
- Ratchet implementation follows spec but needs real-world validation
129
+
- No session recovery from corrupted state
130
+
131
+
## Build & Test
132
+
```bash
133
+
cd /workspace/mymatrix/project/ocaml-matrix
134
+
dune build
135
+
dune runtest
136
+
```
137
+
138
+
## Architecture Notes
139
+
- Olm module provides session management for E2EE (X3DH, Double Ratchet, Megolm)
140
+
- UIAA module supports password, recaptcha, email, and dummy authentication flows
141
+
- Timeline module uses LinkedChunk for efficient pagination (based on matrix-rust-sdk pattern)
142
+
- Store module provides pluggable storage with in-memory implementations
143
+
- Verification module supports SAS (emoji/decimal) and QR code verification structures
144
+
- Backup module implements m.megolm_backup.v1.curve25519-aes-sha2 encryption
145
+
- Send_queue module provides offline queueing with dependency tracking and retry logic
146
+
- Protocol types have 39 roundtrip tests; client modules need integration tests
147
+
148
+
## Comparison with matrix-rust-sdk
149
+
The OCaml SDK now covers most major features of matrix-rust-sdk:
150
+
- ✅ Core client operations (auth, sync, rooms, messages)
151
+
- ✅ E2EE primitives (Olm, Megolm, key management)
152
+
- ✅ Cross-signing key structures and verification protocols
153
+
- ✅ Key backup encryption/decryption
154
+
- ✅ Send queue with dependency system
155
+
- ✅ Timeline caching with LinkedChunk
156
+
- ✅ Pluggable storage architecture
157
+
- ⚠️ Verification flows need to-device message integration
158
+
- ⚠️ Backup needs server API integration
159
+
- ⚠️ Storage needs persistent implementations
160
+
- ❌ Sliding sync (MSC3575) - stub only
161
+
- ❌ Secret storage (m.secret_storage.v1)

3

This library provides a Matrix client implementation using Eio idioms:
4
+
5
+
{b Structured Concurrency}: All operations respect Eio switches for
6
+
proper resource cleanup and cancellation.
7
+
8
+
{b Exception-based Errors}: Operations raise [Eio.Io] exceptions instead
9
+
of returning Result types, making code more readable and allowing
10
+
natural error propagation.
11
+
12
+
{b Fibre-based Sync}: The sync loop runs in a dedicated fibre that can
13
+
be cancelled via the controlling switch.

+

{2 Error Handling}
44
+
45
+
All operations can raise [Eio.Io] exceptions. Use [try...with] or
46
+
[Eio.Switch.run] for proper error handling:
47
+
48
+
{[
49
+
try
50

]}
59
+
60
+
{2 Cancellation}
61
+
62
+
Operations can be cancelled by releasing the switch:
63

64
+
{[
65

standardized structure.

11

- {b To-Device Events}: Direct device-to-device messages (for E2EE)
12
+
- {b Account Data}: Per-user configuration (tags, read markers)
13
