From ed8781f011f87021389b4d1dcc8cd2e9f7e15f5b Mon Sep 17 00:00:00 2001 From: Luke Hinds Date: Mon, 25 Nov 2024 11:08:08 +0000 Subject: [PATCH 1/5] Modular Prompt System MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * Add prompts/default.yaml with built-in system prompts * Implement PromptConfig for managing prompts configuration * Add support for loading prompts from YAML files * Support overriding prompts via CLI, env vars, and config * Add comprehensive test coverage for prompts functionality * Move ConfigurationError to separate exceptions module * Update CLI to display number of loaded prompts The modular prompts system allows users to: * Use default stacklok prompts from prompts/default.yaml * Override with custom prompts via --prompts flag * Define prompts inline in config.yaml * Set prompts via CODEGATE_PROMPTS_FILE env var Tests: ✅ 44 passing (78% coverage) --- config.yaml.example | 28 ++--- prompts/default.yaml | 70 +++++++++++ src/codegate/__init__.py | 23 ++-- src/codegate/cli.py | 44 ++++++- src/codegate/config.py | 62 +++++++--- src/codegate/exceptions.py | 8 ++ src/codegate/prompts.py | 72 ++++++++++++ tests/data/demo-prompts.yaml | 6 + tests/data/invalid_prompts.yaml | 5 + tests/test_cli.py | 50 +++++--- tests/test_cli_prompts.py | 73 ++++++++++++ tests/test_prompts.py | 198 ++++++++++++++++++++++++++++++++ 12 files changed, 583 insertions(+), 56 deletions(-) create mode 100644 prompts/default.yaml create mode 100644 src/codegate/exceptions.py create mode 100644 src/codegate/prompts.py create mode 100644 tests/data/demo-prompts.yaml create mode 100644 tests/data/invalid_prompts.yaml create mode 100644 tests/test_cli_prompts.py create mode 100644 tests/test_prompts.py diff --git a/config.yaml.example b/config.yaml.example index 8936cfbd..dcf3db30 100644 --- a/config.yaml.example +++ b/config.yaml.example @@ -1,17 +1,19 @@ -# Codegate Example Configuration +# Example configuration file +# Copy this file to config.yaml and modify as needed -# Network settings -port: 8989 # Port to listen on (1-65535) -host: "localhost" # Host to bind to (use localhost for all interfaces) +# Server configuration +port: 8989 +host: "localhost" # Logging configuration -log_level: "INFO" # One of: ERROR, WARNING, INFO, DEBUG -log_format: "JSON" # One of: JSON, TEXT +log_level: "INFO" # ERROR, WARNING, INFO, DEBUG +log_format: "JSON" # JSON, TEXT -# Note: This configuration can be overridden by: -# 1.
