7
-
**✅ COMPLETED ITEMS (Phase 1-4 Complete)**:
8
-
- Items 1-12 from original TODO list have been implemented
9
-
- Core JSON handling, method support, vendor extensions, and utilities are functional
10
-
- Apple Mail color flag support, size-based filtering, request builders, and analytics are working
7
+
The library has undergone a significant architectural change, moving from a complex GADT-based DSL to a simpler ADT-based approach with abstract types and constructor functions.

12
-
**🔄 REMAINING WORK**: Despite significant progress, **extensive manual JSON parsing still exists** in all example binaries. The analysis below identifies 38+ missing functions needed for complete elimination.
9
+
**Previous Architecture (REMOVED)**:
10
+
- `jmap-dsl` module with GADT-based method chaining
11
+
- Complex type-level programming with `@>` operators
12
+
- Automatic method execution and response deserialization
13
+
14
+
**New Architecture (IMPLEMENTED)**:
15
+
- ADT-based method construction with `Jmap_method` module
16
+
- Type-safe response parsing with `Jmap_response` module
17
+
- High-level request building with `Jmap_request` module
18
+
- Constructor functions with optional arguments and sensible defaults
19
+
- Abstract types for better encapsulation

### 13. **Method-Specific Request Builders**
25
+
### 1. **Core ADT Infrastructure**
26
+
- [x] Removed `jmap-dsl` module completely
27
+
- [x] Created `Jmap_method` module with:
28
+
- Abstract type `t` for methods
29
+
- Constructor functions for all JMAP methods
30
+
- Optional arguments with sensible defaults
31
+
- Internal JSON serialization
32
+
- Basic jmap-sigs METHOD_ARGS integration
33
+
- [x] Created `Jmap_response` module with:
34
+
- Abstract type `t` for responses
35
+
- Pattern matching support via `response_type`
36
+
- Typed accessor modules for each method
37
+
- Safe extraction functions with Result types
38
+
- Full jmap-sigs METHOD_RESPONSE signature compliance
39
+
- [x] Created `Jmap_request` module with:
40
+
- Type-safe request building
41
+
- Method management and call ID generation
42
+
- Result reference support
43
+
- Wire protocol conversion
19
44
20
-
**Problem**: All 10 examples still manually construct method-specific JSON using `Assoc` patterns.
45
+
### 2. **Method Constructors Implemented**
46
+
- [x] Core/echo
47
+
- [x] Email/query, Email/get, Email/set, Email/changes, Email/copy, Email/import, Email/parse
48
+
- [x] Mailbox/query, Mailbox/get, Mailbox/set, Mailbox/changes
49
+
- [x] Thread/get, Thread/changes
50
+
- [x] Identity/get, Identity/set, Identity/changes
51
+
- [x] EmailSubmission/set, EmailSubmission/query, EmailSubmission/get, EmailSubmission/changes
52
+
- [x] VacationResponse/get, VacationResponse/set
53
+
- [x] SearchSnippet/get
21
54
22
-
**Required Functions**:
55
+
### 3. **Response Parsers Implemented**
56
+
- [x] All method response types with typed accessors
57
+
- [x] Error response handling
58
+
- [x] Pattern matching support for response type discrimination
59
+
60
+
### 4. **jmap-sigs Integration & Code Quality (NEW)**
61
+
- [x] Fixed all build warnings by implementing missing parser cases
62
+
- [x] Removed unused opens and cleaned up code structure
63
+
- [x] Applied jmap-sigs METHOD_RESPONSE signature to all response modules
64
+
- [x] Simplified interface files using signature includes
65
+
- [x] Consistent error handling with Jmap_error.error throughout
66
+
- [x] ~29% reduction in jmap_response.mli interface size (364 → 259 lines)
67
+
- [x] Clean builds with no warnings: `opam exec -- dune build @check`
68
+
- [x] Documentation builds successfully: `opam exec -- dune build @doc`

## **📋 Remaining Work**
73
+
74
+
### Priority 1: **Complete Object Serialization/Deserialization**
75
+
76
+
While the ADT infrastructure is in place, the actual JMAP objects (Email, Mailbox, Thread, etc.) still need complete JSON serialization:
77
+
78
+
#### **Email Object**
23
79
```ocaml
24
-
(* High-level method request builders *)
25
80
module Jmap_email : sig
26
-
module Query : sig
27
-
val to_json : Query_args.t -> Yojson.Safe.t
28
-
end
29
-
30
-
module Get : sig
31
-
val to_json : Get_args.t -> Yojson.Safe.t
81
+
module Email : sig
82
+
type t (* Already exists *)
83
+
val of_json : Yojson.Safe.t -> (t, string) result (* TODO *)
84
+
val to_json : t -> Yojson.Safe.t (* TODO *)
85
+
val to_json_with_properties : properties:string list -> t -> Yojson.Safe.t (* TODO *)
32
86
end
33
87
end
88
+
```
34
89
90
+
#### **Mailbox Object**
91
+
```ocaml
92
+
module Jmap_mailbox : sig
93
+
type t (* Already exists *)
94
+
val of_json : Yojson.Safe.t -> (t, string) result (* TODO *)
95
+
val to_json : t -> Yojson.Safe.t (* TODO *)
96
+
end
97
+
```
98
+
99
+
#### **Thread Object**
100
+
```ocaml
35
101
module Jmap_thread : sig
36
-
module Query : sig
37
-
val to_json : Query_args.t -> Yojson.Safe.t
38
-
end
39
-
40
-
module Get : sig
41
-
val to_json : Get_args.t -> Yojson.Safe.t
42
-
end
102
+
type t (* Already exists *)
103
+
val of_json : Yojson.Safe.t -> (t, string) result (* TODO *)
104
+
val to_json : t -> Yojson.Safe.t (* TODO *)
43
105
end
44
-
45
-
(* Similar patterns for Mailbox, Submission, Identity, VacationResponse *)
46
106
```
47
107
48
-
**Impact**: Eliminates ~40-50 lines per example. **Critical for all 10 examples.**
49
-
50
-
---
51
-
52
-
### 14. **Result Reference Management**
53
-
54
-
**Problem**: All examples manually construct result reference JSON with hardcoded paths.
55
-
56
-
**Required Functions**:
108
+
#### **Identity Object**
57
109
```ocaml
58
-
(* In jmap/jmap_protocol.ml *)
59
-
module Result_reference : sig
60
-
type t
61
-
62
-
val create : method_call_id:string -> method_name:string -> path:string -> t
63
-
val to_json : t -> Yojson.Safe.t
64
-
val ids_reference : method_call_id:string -> t (* shorthand for /ids path *)
65
-
val list_reference : method_call_id:string -> t (* shorthand for /list path *)
110
+
module Jmap_identity : sig
111
+
type t (* Already exists *)
112
+
val of_json : Yojson.Safe.t -> (t, string) result (* TODO *)
113
+
val to_json : t -> Yojson.Safe.t (* TODO *)
66
114
end
67
115
```
68
116
69
-
**Impact**: Eliminates ~10 lines per example. **Affects all 10 examples.**
70
-
71
-
---
72
-
73
-
### 15. **Method Response Parsers**
74
-
75
-
**Problem**: All examples use `Yojson.Safe.Util` for extensive response parsing.
76
-
77
-
**Required Functions**:
117
+
#### **EmailSubmission Object**
78
118
```ocaml
79
-
(* Response parsing for all method types *)
80
-
module Jmap_email : sig
81
-
module Query : sig
82
-
module Response : sig
83
-
val from_json : Yojson.Safe.t -> (t, Error.t) result
84
-
val ids : t -> string list
85
-
val total : t -> int option
86
-
end
87
-
end
88
-
89
-
module Get : sig
90
-
module Response : sig
91
-
val from_json : Yojson.Safe.t -> (t, Error.t) result
92
-
val emails : t -> Email.t list
93
-
val not_found : t -> string list
94
-
end
119
+
module Jmap_submission : sig
120
+
module EmailSubmission : sig
121
+
type t (* Already exists *)
122
+
val of_json : Yojson.Safe.t -> (t, string) result (* TODO *)
123
+
val to_json : t -> Yojson.Safe.t (* TODO *)
95
124
end
96
125
end
126
+
```
97
127
98
-
(* Similar for Thread, Mailbox, Submission, Identity, VacationResponse *)
128
+
#### **VacationResponse Object**
129
+
```ocaml
130
+
module Jmap_vacation : sig
131
+
type t (* Already exists *)
132
+
val of_json : Yojson.Safe.t -> (t, string) result (* TODO *)
133
+
val to_json : t -> Yojson.Safe.t (* TODO *)
134
+
end
99
135
```
100
136
101
-
**Impact**: Eliminates ~20-30 lines per example. **Affects all 10 examples.**
102
-
103

105
-
### 16. **Object Type Parsers**
139
+
### Priority 2: **Filter and Comparator Serialization**
106
140
107
-
**Problem**: Extensive manual parsing of JMAP object types using `member` and `to_*` functions.
141
+
Complete the serialization for query filters and sorting:
108
142
109
-
**Required Functions**:
110
143
```ocaml
111
-
(* Object parsing - the most critical missing piece *)
112
-
module Jmap_email_types : sig
113

val to_json : t -> Yojson.Safe.t (* Partial - needs completion *)
147
+
val of_json : Yojson.Safe.t -> (t, string) result (* TODO *)
152
148
end
153
-
```
154
149
155
-
**Impact**: Eliminates ~30-40 lines per example. **Most critical missing functionality.**
150
+
module Jmap.Methods.Comparator : sig
151
+
type t (* Already exists *)
152
+
val to_json : t -> Yojson.Safe.t (* TODO *)
153
+

### 17. **Attachment and Body Part Parsers**
159
+
### Priority 3: **Patch Operations**
160
160
161
-
**Problem**: Manual parsing of attachment lists and body structures in `query_large_attachments.ml`.
161
+
For /set methods, implement patch operations:
162
162
163
-
**Required Functions**:
164
163
```ocaml
165
-
module Jmap_email_types : sig
166
-
module Attachment : sig
167
-
val from_json : Yojson.Safe.t -> (t, Error.t) result
168
-
val list_from_json : Yojson.Safe.t -> (t list, Error.t) result
169
-
val name : t -> string option
170
-
val size : t -> int option
171
-
val content_type : t -> string option
172
-
end
173
-
174
-
module BodyPart : sig
175
-
val from_json : Yojson.Safe.t -> (t, Error.t) result
176
-
val attachments : t -> Attachment.t list
177
-
end
164
+
module Email_patch : sig
165
+
type t
166
+
val create : unit -> t
167
+
val set_keywords : t -> keywords:Keywords.t -> t
168
+
val add_keyword : t -> keyword:string -> t
169
+
val remove_keyword : t -> keyword:string -> t
170
+
val set_mailbox_ids : t -> mailbox_ids:string list -> t
171
+
val to_json : t -> Yojson.Safe.t
178
172
end
173
+
174
+
(* Similar for Mailbox_patch, Identity_patch, etc. *)
179
175
```
180
176
181
-
**Impact**: Eliminates ~20 lines in attachment-related examples.
182

185
-
### 18. **High-Level Client Interface**
179
+
### Priority 4: **Set Error Handling**
186
180
187
-
**Problem**: All examples manually orchestrate request building, sending, and response parsing.
181
+
Complete error types for /set operations:
188
182
189
-
**Required Functions**:
190
183
```ocaml
191
-
(* In jmap-unix/jmap_unix.ml - high-level client interface *)
192
-
module Client : sig
193
-
type t
194
-
195
-
val query_emails : t -> account_id:string -> filter:Email_filter.t ->
196
-
?sort:Email_sort.t list -> ?limit:int -> unit ->
197
-
(Email.t list * int option) Error.result
198
-
199
-
val get_emails : t -> account_id:string -> ids:string list ->
200
-
?properties:string list -> unit ->
201
-
Email.t list Error.result
202
-
203
-
val query_and_get_emails : t -> account_id:string -> filter:Email_filter.t ->
204
-
?sort:Email_sort.t list -> ?limit:int ->
205
-
?properties:string list -> unit ->
206
-
(Email.t list * int option) Error.result
207
-
208
-
(* Similar high-level functions for threads, submissions, etc. *)
184
+
module Set_error : sig
185
+
type t = {
186
+
error_type : [`InvalidProperties | `NotFound | `OverQuota | `TooLarge | `Other of string];
187
+
description : string option;
188
+
properties : string list option;
189
+
}
190
+
val of_json : Yojson.Safe.t -> (t, string) result
191
+
val to_json : t -> Yojson.Safe.t
209
192
end
210
193
```
211
194
212
-
**Impact**: Could reduce examples from ~300 lines to ~50-100 lines each.
195
+
---
213
196
214
-
---
197
+
### Priority 5: **Update Examples**
215
198
216
-
## **Implementation Analysis**
199
+
Update all example binaries to use the new ADT-based API:
217
200
218
-
### **Current Status After Phase 1-4**:
219
-
- ✅ Core infrastructure is solid (types, basic JSON, method builders)
220
-
- ✅ Request building framework exists
221
-
- ✅ Response processing utilities exist
222
-
- ✅ Vendor extensions (Apple Mail) implemented
223
-
- ✅ Analytics and filtering utilities added
201
+
- [ ] Update `bin/jmap_email_search.ml`
202
+
- [ ] Update `bin/jmap_mailbox_explorer.ml`
203
+
- [ ] Update `bin/jmap_thread_analyzer.ml`
204
+
- [ ] Update `bin/jmap_identity_monitor.ml`
205
+
- [ ] Update `bin/jmap_flag_manager.ml`
206
+
- [ ] Update `bin/jmap_email_composer.ml`
207
+
- [ ] Update `bin/jmap_blob_downloader.ml`
208
+
- [ ] Update `bin/jmap_push_listener.ml`
209
+
- [ ] Update `bin/jmap_vacation_manager.ml`
210
+
- [ ] Update all `bin/examples/*.ml` files
224
211
225
-
### **Remaining Work (Phase 5)**:
226
-
The examples still contain **extensive manual JSON parsing** because:
212
+
---
227
213
228
-
1. **Method-specific builders** (items 13-14) are not fully integrated
229
-
2. **Response parsing** (item 15) exists in core but not exposed at method level
230
-
3. **Object type parsers** (item 16) are the most critical missing piece - these handle the bulk of manual JSON parsing
231
-
4. **High-level client interface** (item 18) would provide the biggest developer experience improvement
214
+
### Priority 6: **Testing**
232
215
233
-
### **Critical Path for Complete Elimination**:
216
+
Create comprehensive tests for the new ADT-based API:
234
217
235
-
**Priority 1: Object Type Parsers (Item 16)**
236
-
- `Email.from_json`, `Thread.from_json`, etc. - eliminates ~30 lines per example
237
-
- This is the **single most impactful missing functionality**
218
+
- [ ] Method constructor tests
219
+
- [ ] Response parser tests
220
+
- [ ] Request builder tests
221
+
- [ ] Round-trip serialization tests
222
+
- [ ] Error handling tests
238
223
239
-
**Priority 2: Method Response Integration (Item 15)**
240
-
- Connect existing response parsers to method-specific interfaces
241
-
- Eliminates ~20 lines per example
224
+
---
242
225
243
-
**Priority 3: Request Builder Integration (Items 13-14)**
244
-
- Connect existing request builders to method-specific interfaces
245
-
- Eliminates ~40 lines per example
226
+
## **Implementation Strategy**
246
227
247
-
**Priority 4: High-Level Client (Item 18)**
248
-
- Combines everything into developer-friendly API
249
-
- Could eliminate ~150+ lines per example
228
+
### Phase 1: **Object Serialization** (Highest Priority)
229
+
Focus on implementing `of_json`/`to_json` for all JMAP objects. This will eliminate the most manual JSON handling in examples.
250
230
251
-
## **Updated Success Metrics**
231
+
### Phase 2: **Complete ADT Integration**
232
+
Ensure all filters, comparators, and patch operations work seamlessly with the ADT approach.
252
233
253
-
- **Current**: Examples average ~300 lines with ~70% still manual JSON handling
254
-
- **After Phase 5**: Examples should average ~100-150 lines with 0% manual JSON handling
255
-
- **Type Safety**: All JMAP operations use library types instead of raw JSON
256
-
- **Developer Experience**: Simple function calls instead of multi-step JSON orchestration
234
+
### Phase 3: **Example Migration**
235
+
Update all examples to demonstrate the new API, showing best practices and common patterns.
257
236
258
-
## **Next Steps**
237
+
### Phase 4: **Documentation**
238
+
- Update module documentation with examples
239
+
- Create a migration guide from DSL to ADT
240
+
- Write a comprehensive README showing the new approach
259
241
260
-
The **object type parsers** (Item 16) should be the immediate focus, as they will eliminate the most manual JSON handling with the least implementation effort. The infrastructure is in place - what's missing is connecting the parsers to the high-level interfaces used by the examples.
242
+
### Phase 5: **Testing & Validation**
243
+
- Implement comprehensive test suite
244
+
- Validate against real JMAP servers
245
+
- Performance benchmarking

## Implementation Priority
249
+
## **Benefits of New Architecture**
265
250
266
-
1. **Phase 1**: Items 1-3 (JSON handling) - Eliminates most manual JSON usage
267
-
2. **Phase 2**: Items 4-7 (Method support) - Enables all JMAP methods
268
-
3. **Phase 3**: Items 8-9 (Extensions) - Adds vendor support and advanced filtering
269
-
4. **Phase 4**: Items 10-12 (Utilities) - Improves developer experience
251
+
1. **Simpler API**: Constructor functions are more intuitive than DSL operators
252
+
2. **Better IDE Support**: Autocomplete works better with regular functions
253
+
3. **Easier Debugging**: No complex type-level computations to trace through
254
+
4. **More Flexible**: Users can build requests in any order or pattern they prefer
255
+
5. **Maintainable**: Straightforward code that's easier to extend and modify
270
256
271
-
## Success Metrics
257
+
---
272
258
273
-
- **Before**: Examples average ~300 lines with ~60% manual JSON handling
274
-
- **After**: Examples should average ~180 lines with 0% manual JSON handling
275
-
- **Type Safety**: All JMAP operations use library types instead of raw JSON
276
-
- **Vendor Support**: Apple Mail and other vendor extensions properly supported
259
+
## **Migration Guide Summary**
277
260
278
-
## Testing Strategy
261
+
**Old DSL Approach**:
262
+
```ocaml
263
+
let request =
264
+
email_query ~account_id ~filter () @>
265
+
email_get ~account_id ~ids:[] () @>
266
+
done_
267
+
```
279
268
280
-
For each improvement:
281
-
1. Update the relevant example binary to use the new functionality
282
-
2. Verify the binary compiles and produces identical JMAP output
283
-
3. Add unit tests for the new library functions
284
-
4. Update documentation with the new capabilities
269
+
**New ADT Approach**:
270
+
```ocaml
271
+
let request =
272
+
Jmap_request.create ~using:[...] ()
273
+
|> Jmap_request.add_method
274
+
(Jmap_method.email_query ~account_id ~filter ())
275
+
|> Jmap_request.add_method_with_ref
276
+
(Jmap_method.email_get ~account_id ())
277
+
~reference:("#call-1", "/ids")
278
+
```
285
279
286
-
This TODO list provides a roadmap for transforming the JMAP library from a type-safe foundation into a fully-featured, developer-friendly JMAP client library.
280
+
The new approach is more verbose but significantly clearer and more flexible.

(** Type-safe JMAP method chaining DSL.

-
3
-
This library provides a type-safe way to chain JMAP method calls
4

with automatic response deserialization. Inspired by Ctypes, it uses
5
-
GADTs to track method signatures and response types at compile time.
6

The design separates method definition from execution, allowing for
8
-
flexible composition while maintaining type safety.

(** Type-safe JMAP method representation and construction.

3
+
This module provides abstract types for JMAP methods with constructor functions
4
+
that use optional arguments and sensible defaults. It demonstrates the use of
5
+
jmap-sigs METHOD_ARGS signatures for consistent method argument handling.
6
+
7
+
Each method constructor returns an opaque method value that can be serialized
8
+
to JSON for wire protocol transmission. The module maintains RFC compliance
9
+
while providing a clean, type-safe OCaml interface.

This module provides a high-level interface for building JMAP requests
4

The module supports both single-method requests and complex multi-method
8

requests with automatic method call ID management and result reference
9

support.

This module provides abstract types for JMAP method responses with

It supports pattern matching on different response types and provides

manual JSON parsing.
