What is crul?

crul took mocking back from webmockr and made it a property of the client itself

crul is the R6-based HTTP client underneath much of rOpenSci's package stack, covering synchronous requests, three flavours of async, pagination and retries. Its 1.6.0 release in July 2025 changed where test mocking lives: each client — HttpClient, Async, AsyncVaried — now takes a mocking parameter at initialisation or per method, and the standalone mock() function is deprecated. Mocking used to be something webmockr switched on from outside; it is now a setting on the client.

What is torchvision?

R's torchvision is porting PyTorch's vision stack one task at a time — instance segmentation just landed.

torchvision for R has moved past being a thin tensor-transform helper into a task-complete vision library. The last three releases added dataset loaders by the dozen, then face detection and recognition, and now Mask R-CNN for instance segmentation. The 0.9.0 release also splits the COCO detection loader from a new segmentation loader, cutting memory use roughly in half for detection-only work.

crul took mocking back from webmockr and made it a property of the client itself

◆ Current state

crul is the R6-based HTTP client underneath much of rOpenSci's package stack, covering synchronous requests, three flavours of async, pagination and retries. Its 1.6.0 release in July 2025 changed where test mocking lives: each client — HttpClient, Async, AsyncVaried — now takes a mocking parameter at initialisation or per method, and the standalone mock() function is deprecated. Mocking used to be something webmockr switched on from outside; it is now a setting on the client.

◆ Where it's heading

The async surface has been the growth area for years — retries reached Async, AsyncVaried, AsyncQueue and HttpRequest in 1.4, AsyncQueue gained the response accessors in 1.2, and 1.5.0 wired async requests up to webmockr. The 1.6.0 change reverses that direction of dependency, and it landed within a minute of webmockr's own release severing its tie to vcr. Read together, the rOpenSci HTTP stack is being deliberately untangled so each package can be used without the others.

◆ Prediction

With mock() deprecated rather than removed, the next major release is the likely point of deletion. Expect the remaining work to follow the same decoupling theme rather than adding request features.

R's torchvision is porting PyTorch's vision stack one task at a time — instance segmentation just landed.

◆ Current state

torchvision for R has moved past being a thin tensor-transform helper into a task-complete vision library. The last three releases added dataset loaders by the dozen, then face detection and recognition, and now Mask R-CNN for instance segmentation. The 0.9.0 release also splits the COCO detection loader from a new segmentation loader, cutting memory use roughly in half for detection-only work.

◆ Where it's heading

The pattern is a deliberate walk through PyTorch's torchvision feature matrix: datasets first, then model architectures, then the visualization and transform utilities that make each task usable end to end. Each release breaks a little API to align R naming with upstream PyTorch conventions — `$categories` became `$classes`, `coco_classes()` now matches the 90-class sparse PyTorch layout. Community contributors are doing most of the volume, with maintainers arbitrating the API shape.

◆ Prediction

Expect the next release to fill in the remaining segmentation and detection model families and continue aligning class and label handling with upstream PyTorch, given that every release so far has paired new models with a matching dataset loader.

Frequently asked questions

What is the difference between crul and torchvision?

They serve adjacent needs but don't currently overlap on shipped themes. crul and torchvision are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band). See the at-a-glance table above for a side-by-side breakdown of velocity, recent sparks, and editorial themes.

Is crul better than torchvision?

Sparkpulse doesn't pick a winner — we score release velocity, not feature parity. crul and torchvision are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band).
