What is dialr?

The R phone-number package stopped only parsing numbers and started asking them where they are.

dialr wraps Google's libphonenumber through rJava, giving R a phone vector class that parses, validates and formats international numbers. It has been quiet since August 2022, when the last release removed a pathology where Java would freeze after enough invalid inputs. The package covers parsing, validation, formatting, and the metadata lookups added in 0.3.0.

What is tidyprompt?

An R prompting framework hands its provider plumbing to ellmer and inherits MCP tools

tidyprompt composes LLM prompts out of stackable 'prompt wraps' — answer_as_json(), answer_as_category(), answer_using_tools() — and validates what comes back. Its recent history is one decision: stop maintaining a provider layer. llm_provider_ellmer() arrived experimental, then became the path through which structured output, tool calling and streaming are done natively. The newest release adds dataframe and numeric extraction wraps and lets send_prompt() take an ellmer chat object directly.

The R phone-number package stopped only parsing numbers and started asking them where they are.

◆ Current state

dialr wraps Google's libphonenumber through rJava, giving R a phone vector class that parses, validates and formats international numbers. It has been quiet since August 2022, when the last release removed a pathology where Java would freeze after enough invalid inputs. The package covers parsing, validation, formatting, and the metadata lookups added in 0.3.0.

◆ Where it's heading

Two forces shape the history. One is expansion into what libphonenumber knows beyond the number itself — carrier, geocode, timezone — which happened once, in 2019, and has not been extended since. The other is the ongoing cost of being a Java wrapper inside an R tidyverse: rJava initialisation moved so the :: form works, phone vectors reclassified when tibble 3.0.0 changed how it treats list-based classes, and repeated performance work to make crossing the Java boundary tolerable. The maintainer has floated moving the phone class onto vctrs but has not.

◆ Prediction

The vctrs migration is the one change the maintainer has explicitly signalled, and the hard-deprecated one-shot functions were slated for removal in the next major release; three years of silence make neither imminent.

An R prompting framework hands its provider plumbing to ellmer and inherits MCP tools

◆ Current state

tidyprompt composes LLM prompts out of stackable 'prompt wraps' — answer_as_json(), answer_as_category(), answer_using_tools() — and validates what comes back. Its recent history is one decision: stop maintaining a provider layer. llm_provider_ellmer() arrived experimental, then became the path through which structured output, tool calling and streaming are done natively. The newest release adds dataframe and numeric extraction wraps and lets send_prompt() take an ellmer chat object directly.

◆ Where it's heading

Two lines run together. One is catalogue growth — every release adds a wrap for another answer shape. The other is consolidation onto ellmer, and that is where the leverage is: because ellmer tool definitions are what mcptools::mcp_tools() returns, tidyprompt gained access to Model Context Protocol servers without writing an MCP client. Its own Gemini provider is already marked superseded. Note the feed's stamps lie — 0.1.0, 0.2.0 and 0.3.0 were all published within two hours of each other in reverse version order.

◆ Prediction

The remaining first-party providers are the obvious next thing to fold in: the Gemini one is already superseded, and the Ollama and OpenAI providers carry the same duplicated plumbing. Expect the wrap catalogue to keep growing on top of an increasingly ellmer-only base.
