# Changelog



All notable changes to this project will be documented in this file.



The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),

and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).



## [0.3.0] - 2025-12-11



### Added



- **PTC-Lisp DSL**: Introduced a Lisp-based DSL as a first-class language for LLM interactions, with full parser and evaluator support.

- **Enhanced Evaluations**: Improved testing infrastructure with `Mix` tasks for multi-model evaluations, detailed markdown reporting, and `ModelRegistry`.

- **Clojure Compliance**: Added integration with Babashka to verify PTC-Lisp semantics against real Clojure, ensuring strict alignment.

- **LLM-Friendly Semantics**: Extended the language with flexible key access (string/keyword interoperability) and type coercions to better handle LLM-generated output.

- **Language Extensions**: Added support for set literals, function parameter destructuring, and property-based testing for safety.



### Fixed



- **Workflow Improvements**: Hardened GitHub workflows for PM and Code Review with better prompting and safety checks.

- **Semantic Fixes**: Aligned `update-vals`, `sort-by`, and destructuring behaviors strictly with Clojure specifications.

- **Documentation**: Comprehensive updates to guides, README, and API docs to reflect the new Lisp DSL and migration paths.



## [0.2.0] - 2025-12-05



### Added



- Introspection operations (`keys`, `typeof`) for exploring data structure

- New operations: `sort_by`, `min_by`, `max_by` for better data manipulation

- `PtcRunner.Json.format_error/1` for LLM-friendly error messages

- Explore mode for schema discovery (see demo app)



## [0.1.0] - 2025-12-03



Initial release of PtcRunner - a BEAM-native Elixir library for Programmatic Tool Calling (PTC).



### Features



- JSON-based DSL for safe program execution

- Sandboxed interpreter with configurable timeout and memory limits

- Built-in operations: arithmetic, comparison, collection, string, and logic

- Tool registry for user-defined functions

- JSON Schema generation for LLM structured output

- Comprehensive validation with helpful error messages
