should show

  • services and attached actions

now says nothing

I think its not even connected properly

Implementation Specification for Issue #7: Improve hero_proc list

Objective

Enhance the hero_proc list command to display comprehensive information about services and their attached actions, including:

  • Service names
  • Current running state (not just a symbol)
  • Attached actions per service
  • CPU/memory usage statistics when running
  • Service dependencies and dependency relationships
  • Connection health status

The command should provide users with a clear overview of the entire service ecosystem in a single view.

Current State

The hero_proc list command currently:

  • Calls service.list RPC to get service names
  • Calls service.status for each service individually
  • Outputs a simple 3-column text format: STATUS_SYMBOL SERVICE_NAME STATE (pid)
  • Does not show: attached actions, CPU/memory usage, dependencies, or action counts

Root Cause Analysis

The list command is incomplete because:

  1. Missing Data Retrieval: Only calls service.status, should also call service.list_full, service.stats
  2. No Actions Display: ServiceSpec has actions: Vec<String> but never retrieved
  3. No Resource Metrics: ServiceStats available via service.stats but never fetched
  4. No Dependency Visualization: DependencyDef available but never displayed
  5. Uncertain Connection Status: Silently fails with "unknown" state

Requirements

The enhanced hero_proc list must display:

  1. Service Identification - Name, class, context
  2. Status Information - State with symbol, PID, restart count
  3. Actions - Count and names of attached actions (with "+N more" if many)
  4. Resource Usage - Memory usage (e.g., "42.3 MiB"), CPU percentage (e.g., "12.5%")
  5. Dependencies - Indicator showing dependency relationships
  6. Connection Health - Clear error messages if connection fails

Implementation Plan

The implementation consists of 7 steps:

  1. Step 1: Enhance Data Structures - Create internal ListServiceRow struct and helper formatting functions
  2. Step 2: Rewrite cmd_list Function - Replace simple list with enhanced data fetching and formatting
  3. Step 3: Add Formatting Helper Functions - Implement utility functions for consistent data presentation
  4. Step 4: Implement Column Alignment - Calculate column widths and format output rows
  5. Step 5: Add Error Handling - Improve error messages for connection issues
  6. Step 6: Update Command Line Arguments - Add optional format/filter/sort flags
  7. Step 7: Write Tests - Add comprehensive integration tests

Files to Modify

  • crates/hero_proc/src/cli/commands.rs - Rewrite cmd_list function
  • crates/hero_proc/src/cli/formatting.rs - Extend formatting system
  • crates/hero_proc/src/cli/args.rs - Add output format flags (optional)
  • tests/integration/tests/commands/list_status.rs - Add tests

Acceptance Criteria

✓ Services display name, state, PID, actions, memory, CPU, dependencies
✓ All columns properly aligned and readable
✓ Shows "—" for unavailable metrics (stopped services)
✓ Shows "+N more" for services with many actions
✓ Clear error message when server not running
✓ List command completes in < 2 seconds for typical setup
✓ No regressions in existing tests

Notes

  • Use service.list_full once instead of N service.get calls
  • Consider parallel service.stats calls for performance
  • Use binary format (KiB, MiB, GiB) for memory
  • Add --with-deps flag for full dependency tree view

Ready for review. Please confirm the approach and we'll proceed with implementation.

## Implementation Specification for Issue #7: Improve hero_proc list ### Objective Enhance the `hero_proc list` command to display comprehensive information about services and their attached actions, including: - Service names - Current running state (not just a symbol) - Attached actions per service - CPU/memory usage statistics when running - Service dependencies and dependency relationships - Connection health status The command should provide users with a clear overview of the entire service ecosystem in a single view. ### Current State The `hero_proc list` command currently: - Calls `service.list` RPC to get service names - Calls `service.status` for each service individually - Outputs a simple 3-column text format: `STATUS_SYMBOL SERVICE_NAME STATE (pid)` - **Does not show**: attached actions, CPU/memory usage, dependencies, or action counts ### Root Cause Analysis The list command is incomplete because: 1. **Missing Data Retrieval**: Only calls `service.status`, should also call `service.list_full`, `service.stats` 2. **No Actions Display**: ServiceSpec has `actions: Vec<String>` but never retrieved 3. **No Resource Metrics**: ServiceStats available via `service.stats` but never fetched 4. **No Dependency Visualization**: DependencyDef available but never displayed 5. **Uncertain Connection Status**: Silently fails with "unknown" state ### Requirements The enhanced `hero_proc list` must display: 1. **Service Identification** - Name, class, context 2. **Status Information** - State with symbol, PID, restart count 3. **Actions** - Count and names of attached actions (with "+N more" if many) 4. **Resource Usage** - Memory usage (e.g., "42.3 MiB"), CPU percentage (e.g., "12.5%") 5. **Dependencies** - Indicator showing dependency relationships 6. **Connection Health** - Clear error messages if connection fails ### Implementation Plan The implementation consists of 7 steps: 1. **Step 1: Enhance Data Structures** - Create internal `ListServiceRow` struct and helper formatting functions 2. **Step 2: Rewrite cmd_list Function** - Replace simple list with enhanced data fetching and formatting 3. **Step 3: Add Formatting Helper Functions** - Implement utility functions for consistent data presentation 4. **Step 4: Implement Column Alignment** - Calculate column widths and format output rows 5. **Step 5: Add Error Handling** - Improve error messages for connection issues 6. **Step 6: Update Command Line Arguments** - Add optional format/filter/sort flags 7. **Step 7: Write Tests** - Add comprehensive integration tests ### Files to Modify - `crates/hero_proc/src/cli/commands.rs` - Rewrite cmd_list function - `crates/hero_proc/src/cli/formatting.rs` - Extend formatting system - `crates/hero_proc/src/cli/args.rs` - Add output format flags (optional) - `tests/integration/tests/commands/list_status.rs` - Add tests ### Acceptance Criteria ✓ Services display name, state, PID, actions, memory, CPU, dependencies ✓ All columns properly aligned and readable ✓ Shows "—" for unavailable metrics (stopped services) ✓ Shows "+N more" for services with many actions ✓ Clear error message when server not running ✓ List command completes in < 2 seconds for typical setup ✓ No regressions in existing tests ### Notes - Use `service.list_full` once instead of N `service.get` calls - Consider parallel `service.stats` calls for performance - Use binary format (KiB, MiB, GiB) for memory - Add `--with-deps` flag for full dependency tree view --- **Ready for review.** Please confirm the approach and we'll proceed with implementation.

Test Results

Summary

  • Total Tests: 93
  • Passed: 90
  • Failed: 3
  • Skipped: 0
  • Duration: ~3 seconds

Test Status

✅ Compilation: SUCCESS
❌ Test Execution: 3 FAILURES

Failed Tests

  1. commands::config_ops::tests::test_config_diff_help - Command not implemented
  2. commands::config_ops::tests::test_config_import_help - Command not implemented
  3. commands::system_commands::tests::test_reload_help - Command not implemented

Test Breakdown

  • Library tests (hero_proc_lib): 84 passed
  • Integration tests: 4 passed
  • CLI integration tests: 86 passed, 3 failed

Root Cause Analysis

The failing tests are attempting to verify help text for CLI commands that don't exist in the current codebase:

  • config import / config diff: The ConfigCommand enum in crates/hero_proc/src/cli/args.rs only includes Validate and Export variants, but tests expect Import and Diff commands.
  • reload: There is no Reload variant in the top-level Commands enum.

These appear to be tests for planned/incomplete features that reference CLI subcommands that have not yet been implemented.

Action Items

Either:

  1. Remove tests for unimplemented commands, OR
  2. Implement the missing CLI subcommands (config import, config diff, and reload)
## Test Results ### Summary - **Total Tests**: 93 - **Passed**: 90 - **Failed**: 3 - **Skipped**: 0 - **Duration**: ~3 seconds ### Test Status ✅ **Compilation**: SUCCESS ❌ **Test Execution**: 3 FAILURES ### Failed Tests 1. `commands::config_ops::tests::test_config_diff_help` - Command not implemented 2. `commands::config_ops::tests::test_config_import_help` - Command not implemented 3. `commands::system_commands::tests::test_reload_help` - Command not implemented ### Test Breakdown - Library tests (hero_proc_lib): 84 passed - Integration tests: 4 passed - CLI integration tests: 86 passed, 3 failed ### Root Cause Analysis The failing tests are attempting to verify help text for CLI commands that don't exist in the current codebase: - **`config import` / `config diff`**: The `ConfigCommand` enum in `crates/hero_proc/src/cli/args.rs` only includes `Validate` and `Export` variants, but tests expect `Import` and `Diff` commands. - **`reload`**: There is no `Reload` variant in the top-level `Commands` enum.
