jinja : attribute support for join, map and sort by CISC · Pull Request #18883 · ggml-org/llama.cpp

CISC · 2026-01-16T20:33:42Z

Adds attribute support (int for arrays and str for objects), for join, map and sort filters.

Adds support for negative array index and default in value->at().

-                throw not_implemented_exception("array attribute join not implemented");
-            }
+            value val_delim = args.get_kwarg_or_pos("d",         1);
+            value attribute = args.get_kwarg_or_pos("attribute", 2);


both map, sort, join can have attribute, probably we can find a way to abstract out the attribute handling?

Maybe, but didn't immediately see how since they are applied differently.

+            value val_case    = args.get_kwarg_or_pos("case_sensitive", 2);
+            value attribute   = args.get_kwarg_or_pos("attribute",      3);
+            // FIXME: sorting is case sensitive
+            //const bool case_sensitive = val_case->as_bool(); // undefined == false


maybe throw not_implemented_exception if case_sensitive is set?

It's the other way around, case_sensitive=False is default, but we are always case sensitive ATM.

+        }
+        return val_arr[index];
+    }
+    virtual value & at(int64_t index) {


I'm not quite sure why I placed the at(...) inside value_t in the first place, probably better to place them inside value_array_t and value_object_t respectively - let's have a look in a follow-up PR

ngxson · 2026-01-16T21:32:25Z

+                        val_a = a->at(attr_name);
+                        val_b = b->at(attr_name);
+                    } else {
+                        throw raised_exception("sort: unsupported object attribute comparison");


maybe also log the type of a and b in the message, so that it's easier to debug in the future

I didn't want to add std::format here since it's not used anywhere else.

I mean you can just use string concat +, we already doing that in multiple places. Not the best, but it makes debugging much easier.

I think I spaced out a little, thinking I needed to format values or something. :)

I'll fix it in the next PR which will touch this code anyway.

Merging now, let's address open suggestions if applicable in follow-ups.

* support negative array index and default value * attribute support (int and str) for join, map and sort * add tests * update CODEOWNERS * improve fixme sorting comment

This broke tool-calling for Qwen3-Coder and any other model whose chat template uses the 'in' test. Added test_is_in supporting array, string, and object containment checks, mirroring the existing 'in' operator logic in runtime.cpp. Includes test cases for all three containment types plus reject/select filter usage.

For vision models (e.g. LFM2.5-VL-1.6B and Qwen/Qwen3-VL-4B-Instruct) `llama-mtmd-cli` produces identical output to HF implementation. However `llama-server` doesn't. I traced it down to extra newline inserted after `<__media__>`. This happens in `to_json_oaicompat`, that treats media markers as text and joins all parts with `\n` separator. PR introduces new type `media_marker` and uses it for media markers. Extra logic is added to prevent insertion of newlines before and after media markers. With this change number of input tokens is identical to HF implementation and as a result the output is also identical. I explored other ways to address the issue * remove completely `\n` between text parts in `to_json_oaicompat` * merge text messages in server-common.cpp before sending them to `to_json_oaicompat` Please propose alternative ways of fixing this issue.
