Add factory introspection CLI commands: --list-available-factories and --print-factory-info #2023

Copilot · 2025-08-19T21:12:22Z

This PR implements two new CLI help commands for eicrecon to provide better plugin and factory introspection capabilities, addressing the need for users to understand the available factories and their relationships within the EICrecon framework.

New Commands

`--list-available-factories <plugin>`

Query plugins for available factories within them, similar to the existing --list-available-plugins command.

eicrecon --list-available-factories EEMC

Features:

Lists all factories provided by a specific plugin in a clean table format
Shows factory object names, tags, and descriptions
Smart error handling: displays available plugins when target plugin not found
Includes summary count of factories per plugin

`--print-factory-info`

Query factories for comprehensive system information and provide detailed factory overview.

eicrecon --print-factory-info

Features:

Shows detailed information about all factories in the system
Displays factory summary statistics and breakdowns by plugin
Includes heuristic analysis of collection naming patterns (e.g., Ecal*, Hcal*)
Provides user guidance on accessing detailed input/output information

Implementation Details

The implementation follows existing CLI patterns and integrates seamlessly with the current command structure:

Extended Flag enum: Added ListPluginFactories and PrintFactoryInfo flags
Enhanced UserOptions: Added plugin_name field for plugin-specific queries
Command parsing: Added proper tokenizer entries and case handlers
Error handling: Comprehensive validation with user-friendly error messages
Consistent formatting: Uses existing JTablePrinter for uniform output

Testing

Added comprehensive CI testing in the GitHub Actions workflow with a dedicated test-factory-cli job that validates both commands work correctly in the eic-shell environment.

Documentation

Added comprehensive user documentation at docs/tutorial/05-factory-help-commands.md with:

Detailed usage examples and command syntax
Technical notes on accessing input/output collection information
Guidance on inspecting factory source code for precise I/O specifications
Integration guidance with existing CLI commands

Benefits

This enhancement provides valuable introspection capabilities for EICrecon users:

Plugin developers can easily see what factories their plugins provide
Users can understand the available data processing components
Debugging becomes easier with clear factory organization by plugin
Learning is facilitated through pattern analysis and comprehensive overviews

The commands complement the existing --list-available-plugins and --list-factories options, providing a complete hierarchy of introspection from plugins → factories → detailed information.

Future Extensions

The implementation provides a foundation for future enhancements when extended JANA API access becomes available, such as runtime access to input/output collection specifications and factory dependency graphs.

@copilot Ensure that GitHub Actions checks succeed.

I've fixed the clang-tidy static analysis issues that were causing the GitHub Actions checks to fail. The main problems were C-style casts that needed to be replaced with static_cast. I also cleaned up some accidentally committed build files.

Changes made in commit 6623f95:

Replaced size_t(3) with static_cast<size_t>(3)
Replaced std::size_t(4) and std::size_t(5) with static_cast<std::size_t>(4) and static_cast<std::size_t>(5)
Applied clang-format to ensure proper line length formatting
Removed build artifacts that were accidentally committed

The GitHub Actions checks should now pass with these clang-tidy compliance fixes.

@copilot There are still compilation failures in the CI checks. Notably the following two:

...

I've fixed the compilation failures identified in the CI checks. The issues were:

Name collision: The PrintFactoryInfo enum value conflicted with the PrintFactoryInfo() function name. I resolved this by renaming the function to ShowFactoryInfo().
Deleted copy constructor: The code was trying to copy JComponentSummary which has a deleted copy constructor. I fixed this by using const auto& cs = app->GetComponentSummary(); instead.
Function call resolution: The name collision caused function calls to be interpreted as enum references. This is now resolved with the function rename.

Changes made in commit d94f23d:

Renamed PrintFactoryInfo() function to ShowFactoryInfo() in both header and implementation
Changed auto cs = app->GetComponentSummary(); to const auto& cs = app->GetComponentSummary(); in both functions
Updated function call from PrintFactoryInfo(app) to ShowFactoryInfo(app)

The CLI command --print-factory-info and all enum handling remain unchanged and functional. Syntax validation tests pass successfully.

@copilot Add a test to linux-eic-shell.yml that runs eicrecon with the new flags to demonstrate correct behavior.

I've added a test job test-factory-cli to the linux-eic-shell.yml workflow that demonstrates both new CLI commands work correctly. The test runs:

eicrecon --list-available-factories EEMC to test the plugin-specific factory listing
eicrecon --print-factory-info to test the comprehensive factory information display

The job follows the same patterns as other workflow jobs, downloading the install directory and setting up the environment properly. This ensures the new introspection commands are tested as part of CI.

Fixed the AddressSanitizer suppressions file error by adding the "Checkout .github" step to the test-factory-cli job, following the same pattern as other CI jobs that use ASAN artifacts. This ensures the .github/asan.supp file is available when running eicrecon with AddressSanitizer enabled.

@copilot Address the readability-braces-around-statements clang-tidy check by making sure single line statement are also surrounded by braces.

I've fixed the readability-braces-around-statements clang-tidy check by adding braces around single-line statements after if conditions. The specific changes were in lines 460-461 and 464-465 where single-line statements std::cout << ", "; and std::cout << ", ..."; were missing braces.
