I would like to build high quality OCaml bindings to the Zulip REST API,
2
+
documented at https://zulip.com/api/rest. As another reference, the Python
3
+
`zulip` library from pip is well maintained.
4
+
5
+
My target is to use the OCaml EIO direct-style library, with an idiomatic as
6
+
possible API that implements it. For JSON parsing, using the jsonm library is
7
+
right. For HTTPS, use cohttp-eio with the tls-eio library.

# OCaml Zulip Library Design
10
+
11
+
Based on analysis of:
12
+
- Zulip REST API documentation: https://zulip.com/api/rest
13
+
- Python zulip library: https://github.com/zulip/python-zulip-api
14
+
- Zulip error handling: https://zulip.com/api/rest-error-handling
15
+
- Zulip send message API: https://zulip.com/api/send-message
16
+
17
+
## Overview
18
+
The library follows OCaml best practices with abstract types (`type t`) per module, comprehensive constructors/accessors, and proper pretty printers. Each core concept gets its own module with a clean interface.
19
+
20
+
## Module Structure
21
+
22
+
### Authentication (`Zulip.Auth`)
23
+
```ocaml
24
+
type t (* abstract *)
25
+
26
+
val create : server_url:string -> email:string -> api_key:string -> t
27
+
val from_zuliprc : ?path:string -> unit -> (t, Error.t) result
28
+
val server_url : t -> string
29
+
val email : t -> string
30
+
val to_basic_auth_header : t -> string
31
+
val pp : Format.formatter -> t -> unit
32
+
```
33
+
34
+

43
+
| Other of string
44
+
45
+
type t (* abstract *)
46
+
47
+
val create : code:code -> msg:string -> ?extra:(string * Jsonm.value) list -> unit -> t

## EIO Bot Framework Extension
232
+
233
+
Based on analysis of the Python bot framework at:
234
+
- https://github.com/zulip/python-zulip-api/blob/main/zulip_bots/zulip_bots/lib.py
235
+
- https://github.com/zulip/python-zulip-api/blob/main/zulip_botserver/zulip_botserver/server.py
236
+
237
+
### Bot Handler (`Zulip.Bot`)
238
+
```ocaml
239
+
module Storage : sig
240
+
type t (* abstract *)
241
+
242
+
val create : Client.t -> t

275
+
val identity : t -> Identity.t
276
+
val storage : t -> Storage.t
277
+
val handle_message : t -> Jsonm.value -> unit
278
+
val send_reply : t -> original_message:Jsonm.value -> content:string -> unit
279
+
val send_message : t -> Message.t -> unit
280
+
```
281
+
282
+
### Bot Server (`Zulip.Bot_server`)
283
+
```ocaml
284
+
module Config : sig
285
+
type bot_config = {
286
+
email : string;
287
+
api_key : string;
288
+
token : string; (* webhook token *)
289
+

290
+

291
+
}
292

val from_file : string -> (t, Error.t) result
297
+
val from_env : string -> (t, Error.t) result
298
+
val host : t -> string
299
+
val port : t -> int
300
+
val bot_configs : t -> bot_config list
301
+
end
302
+
303
+
type t (* abstract *)
304
+
305
+
val create : #Eio.Env.t -> Config.t -> (t, Error.t) result
306
+
307
+
val run : t -> unit
308
+
(* Starts the server using EIO structured concurrency *)
309
+
310
+
val with_server : #Eio.Env.t -> Config.t -> (t -> 'a) -> ('a, Error.t) result
311
+
(* Resource-safe server management *)
312
+
```
313
+
314
+
### Bot Registry (`Zulip.Bot_registry`)
315
+
```ocaml
316
+
type bot_module = {
317
+
name : string;
318
+
handler : Bot.handler;
319
+
create_instance : Client.t -> Bot.t;
320
+
}
321
+
322
+
type t (* abstract *)
323
+
324
+
val create : unit -> t
325
+
val register : t -> bot_module -> unit
326
+
val get_handler : t -> email:string -> Bot.t option
327
+
val list_bots : t -> string list
328
+
329

331
+
val load_from_directory : string -> (bot_module list, Error.t) result
332
+
```
333
+
334
+
### Webhook Handler (`Zulip.Webhook`)
335
+
```ocaml
336
+
type webhook_event = {
337
+
bot_email : string;
338
+
token : string;
339
+
message : Jsonm.value;
340
+
trigger : [`Direct_message | `Mention];
341
+
}
342
+
343
+
type response = {
344
+
content : string option;
345
+
message_type : Message_type.t option;
346
+
to_ : string list option;
347
+
topic : string option;
348
+
}
349
+
350
+
val parse_webhook : string -> (webhook_event, Error.t) result
351
+
val handle_webhook : Bot_registry.t -> webhook_event -> (response option, Error.t) result
352
+
```
353
+
354
+
### Structured Concurrency Design
355
+
356
+
The EIO-based server uses structured concurrency to manage multiple bots safely:
357
+
358
+
```ocaml
359
+
(* Example server implementation using EIO *)
360
+
let run_server env config =
361
+
let registry = Bot_registry.create () in
362
+
363
+
(* Load and register all configured bots concurrently *)
364
+
Eio.Switch.run @@ fun sw ->
365
+
366
+
(* Start each bot in its own fiber *)
367
+
List.iter (fun bot_config ->
368
+
Eio.Fiber.fork ~sw (fun () ->
369
+
let auth = Auth.create
370
+
~server_url:bot_config.server_url
371
+
~email:bot_config.email
372
+
~api_key:bot_config.api_key in
373
+
374
+
Client.with_client env auth @@ fun client ->
375
+
376
+
(* Load bot module *)
377
+
match Bot_registry.load_from_file bot_config.module_name with
378
+
| Ok bot_module ->
379
+
let bot = bot_module.create_instance client in
380
+
Bot_registry.register registry bot_module;
381
+
382
+
(* Keep bot alive and handle events *)
383
+
Event_loop.run client bot
384
+
| Error e ->
385
+
Printf.eprintf "Failed to load bot %s: %s\n"
386
+
bot_config.email (Error.message e)
387
+
)
388
+
) (Config.bot_configs config);
389
+
390
+
(* Start HTTP server for webhooks *)
391
+
let server_addr = `Tcp (Eio.Net.Ipaddr.V4.loopback, Config.port config) in
392
+
Eio.Net.run_server env#net server_addr ~on_error:raise @@ fun flow _addr ->
393
+
394
+
(* Handle each webhook request concurrently *)
395
+
Eio.Switch.run @@ fun req_sw ->
396
+
Eio.Fiber.fork ~sw:req_sw (fun () ->
397
+
handle_http_request registry flow
398
+
)
399
+
```
400
+
401
+
### Event Loop (`Zulip.Event_loop`)
402
+
```ocaml
403
+
type t (* abstract *)
404
+
405
+
val create : Client.t -> Bot.t -> t
406
+
407
+
val run : Client.t -> Bot.t -> unit
408
+
(* Runs the event loop using real-time events API *)
409
+
410
+
val run_webhook_mode : Client.t -> Bot.t -> unit
411
+
(* Runs in webhook mode, waiting for HTTP callbacks *)
412
+
413
+
(* For advanced use cases *)
414
+
val with_event_loop :
415
+
Client.t ->
416
+
Bot.t ->
417
+
(Event_queue.t -> unit) ->
418
+
unit
419
+
```
420
+
421
+
## Key EIO Advantages
422
+
423
+
1. **Structured Concurrency**: Each bot runs in its own fiber with proper cleanup
424
+
2. **Resource Safety**: Automatic cleanup of connections, event queues, and HTTP servers
425
+
3. **Backpressure**: Natural flow control through EIO's cooperative scheduling
426
+
4. **Error Isolation**: Bot failures don't crash the entire server
427
+
5. **Graceful Shutdown**: Structured teardown of all resources
428
+
429
+
## Design Principles
430
+
431
+
1. **Abstract Types**: Each major concept has its own module with abstract `type t`
432
+
2. **Constructors**: Clear `create` functions with optional parameters
433
+
3. **Accessors**: All fields accessible via dedicated functions
434
+
4. **Pretty Printing**: Every type has a `pp` function for debugging
435
+
5. **JSON Conversion**: Bidirectional JSON conversion where appropriate
436
+
6. **Error Handling**: Consistent `(_, Error.t) result` return types
437
+
438
+
## Authentication Strategy
439
+
440
+
- Support zuliprc files and direct credential passing
441
+
- Abstract `Auth.t` prevents credential leakage
442
+
- HTTP Basic Auth with proper encoding
443
+
444
+
## EIO Integration
445
+
446
+
- All operations use EIO's direct-style async
447
+
- Resource-safe client management with `with_client`
448
+
- Proper cleanup of connections and event queues
449
+
450
+
## Example Usage
451
+
452

## Package Dependencies
514
+
515
+
- `eio` - Effects-based I/O
516
+
- `cohttp-eio` - HTTP client with EIO support
517
+
- `tls-eio` - TLS support for HTTPS
518
+
- `jsonm` - Streaming JSON codec
519
+
- `uri` - URI parsing and manipulation

+
- `base64` - Base64 encoding for authentication
521
+
522
+
## Sources and References
523
+
524
+
This design is based on comprehensive analysis of:
525
+
526
+
1. **Zulip REST API Documentation**:
527
+
- Main API: https://zulip.com/api/rest
528
+
- Error Handling: https://zulip.com/api/rest-error-handling
529
+
- Send Message: https://zulip.com/api/send-message
530
+
531
+
2. **Python Zulip Library**:
532
+
- Main repository: https://github.com/zulip/python-zulip-api
533
+
- Bot framework: https://github.com/zulip/python-zulip-api/blob/main/zulip_bots/zulip_bots/lib.py
534
+
- Bot server: https://github.com/zulip/python-zulip-api/blob/main/zulip_botserver/zulip_botserver/server.py
535
+
536
+
The design adapts these Python patterns to idiomatic OCaml with abstract types, proper error handling, and EIO's structured concurrency for robust, type-safe Zulip integration.
