Implement context manager integration that detects API errors indicating context length exceeded, then automatically shrinks message history and retries the request. Add new messages API functions (remove_range, get_object, replace_at) and a new R_ERROR_CONTEXT_TOO_LONG error code to support this functionality.
Add use_tools() helper that reads R_USE_TOOLS environment variable to
conditionally include tools descriptions in chat JSON output, defaulting
to true when unset or unrecognized.
Implement full AppImage packaging support including AppRun entry point, .desktop launcher, icon asset, and recursive shared library collection via collect_so_files.sh. The Makefile build target now generates a portable Linux executable by assembling the directory structure, copying the binary to AppImage/usr/bin/r, running the dependency collector, and invoking appimagetool to produce a self-contained AppImage binary. Also update .gitignore to exclude the AppImage build directory and add shell scripts to the ignore list.
The diff adds a tip about creating bash files for environment variables and symlinking them for easy access, along with new configuration sections for OpenAI (using gpt-4o-mini) and Grok (using grok-2 with strict mode disabled) API setups in the README documentation.
The fix changes the glob pattern from a literal dot to a wildcard asterisk when the target directory is ".", enabling recursive matching of files in subdirectories during the build process.
The change adds a conditional check in `tool_function_directory_rglob` that converts a target_dir of "." to "*", enabling the recursive glob to match files in nested subdirectories rather than only the current directory's immediate contents.
Replace hardcoded global API URL variables with getter functions that check the R_BASE_URL environment variable, falling back to the static defaults. Introduce a joinpath utility in utils.h to safely concatenate a base URL with a path segment, handling trailing slashes and leading path slashes. Remove conditional compilation blocks for RD and OLLAMA backends, consolidating all API URL logic into the new get_completions_api_url and get_models_api_url functions. Update all call sites in openai.h to use the new getter functions instead of direct global variable access.
- Remove the initial commit placeholder progress message from Makefile
- Add `!tools` command to REPL that prints available tools descriptions
- Include tools.h header and integrate tools_descriptions() function
- Switch default RD backend from DeepInfra/Llama to Anthropic/Claude models
- Update advanced_model and fast_model to claude-3-5-haiku-20241022
- Change completions_api_url to Anthropic API endpoint
- Enable verbose mode by default (is_verbose = true)
- Update README to reflect new Claude/Ollama focus and remove old download links
Introduce a new `file_version_history` table to the SQLite schema and implement the `db_store_file_version` function that reads a file's current content and inserts a version record before overwriting it. The `tool_function_write_file` now calls this backup function prior to opening the file for writing, ensuring every write operation creates a recoverable snapshot.
Add build_mingw target using x86_64-w64-mingw32-gcc cross-compiler with
dedicated MinGW flags and publish step. Introduce Dockerfile with Ubuntu
base image installing all required build dependencies (gcc, make, readline,
ncurses, curl, openssl, json-c, sqlite3, python3-dev). Add compose.yml for
convenient Docker-based development shell with mounted working directory.
Extend Makefile with docker, docker_make, docker_run, run_mingw targets and
suppress error output on publish commands for build and build_free targets.
Introduce conditional compilation via OLLAMA preprocessor flag to switch between OpenAI and Ollama API endpoints, model names, and URLs. Add `build_free` and `run_free` Makefile targets for the Ollama variant. Enhance REPL with `!models` command to list available models, improve error handling in `openai_process_chat_message`, and fix history line addition logic.
