# Story 6.5: CLI for Batch Execution
|
|
|
|
Status: done
|
|
|
|
## Story
|
|
|
|
As a **data engineer (David)**,
|
|
I want **a command-line interface for batch thermodynamic simulations**,
|
|
So that **I can process millions of scenarios programmatically without manual intervention**.
|
|
|
|
## Acceptance Criteria
|
|
|
|
1. **Given** a JSON configuration file defining a thermodynamic system
|
|
**When** running `entropyk-cli run config.json`
|
|
**Then** the simulation executes successfully
|
|
**And** results are written to a JSON output file
|
|
|
|
2. **Given** a directory of multiple configuration files
|
|
**When** running `entropyk-cli batch ./scenarios/`
|
|
**Then** all simulations execute in parallel
|
|
**And** progress is reported to stdout
|
|
**And** individual failures don't stop the batch
|
|
|
|
3. **Given** a simulation execution
|
|
**When** the process completes
|
|
**Then** exit code 0 indicates success
|
|
**And** exit code 1 indicates simulation error
|
|
**And** exit code 2 indicates configuration error
|
|
|
|
4. **Given** the CLI binary
|
|
**When** running `entropyk-cli --help`
|
|
**Then** comprehensive usage documentation is displayed
|
|
**And** all commands and options are documented
|
|
|
|
5. **Given** a large batch job
|
|
**When** running with `--parallel N` option
|
|
**Then** N simulations run concurrently
|
|
**And** CPU utilization scales appropriately
|
|
|
|

## Dev Notes
|
|
|
|
### Architecture Compliance
|
|
|
|
- **Crate Location**: `crates/cli/` (follows workspace structure)
|
|
- **Binary Name**: `entropyk-cli` (installable via `cargo install entropyk-cli`)
|
|
- **Dependencies**: Reuse `entropyk` facade crate for all simulation logic
|
|
- **Error Handling**: Use `anyhow` for CLI errors, map `ThermoError` appropriately
|
|
- **Observability**: Use `tracing-subscriber` with optional file logging
|
|
|
|
### CLI Structure Pattern
|
|
|
|
Follow clap derive pattern for clean argument parsing:
|
|
|
|
```rust
|
|
#[derive(Parser)]
|
|
#[command(name = "entropyk-cli")]
|
|
#[command(about = "Batch thermodynamic simulation CLI", long_about = None)]
|
|
struct Cli {
|
|
#[command(subcommand)]
|
|
command: Commands,
|
|
}
|
|
|
|
#[derive(Subcommand)]
|
|
enum Commands {
|
|
Run {
|
|
#[arg(short, long)]
|
|
config: PathBuf,
|
|
#[arg(short, long)]
|
|
output: Option<PathBuf>,
|
|
},
|
|
Batch {
|
|
#[arg(short, long)]
|
|
directory: PathBuf,
|
|
#[arg(short, long, default_value = "4")]
|
|
parallel: usize,
|
|
},
|
|
}
|
|
```
|
|
|
|
### Configuration Schema
|
|
|
|
```json
|
|
{
|
|
"fluid": "R134a",
|
|
"components": [
|
|
{
|
|
"type": "Compressor",
|
|
"name": "comp1",
|
|
"ahri_coefficients": [1.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0]
|
|
},
|
|
{
|
|
"type": "Condenser",
|
|
"name": "cond1",
|
|
"ua": 5000.0
|
|
}
|
|
],
|
|
"edges": [
|
|
{"from": "comp1:outlet", "to": "cond1:inlet"}
|
|
],
|
|
"solver": {
|
|
"strategy": "fallback",
|
|
"max_iterations": 100,
|
|
"tolerance": 1e-6
|
|
}
|
|
}
|
|
```
|
|
|
|
### Project Structure Notes
|
|
|
|
- Binary crate separate from library crates
|
|
- Use `entropyk` facade crate to access all simulation functionality
|
|
- Follow patterns from existing demo binaries in `demo/src/bin/`
|
|
- Use `serde_json` for configuration and output
|
|
|
|
### Critical Constraints
|
|
|
|
1. **No Panics**: All errors must return proper exit codes
|
|
2. **Memory Efficient**: Process large batches without memory growth
|
|
3. **Deterministic Output**: Same config → same JSON output
|
|
4. **Progress Visibility**: User must know batch progress
|

### Previous Story Intelligence
|
|
|
|
From Story 6.1 (Rust Native API):
|
|
- Top-level `entropyk` crate provides unified facade
|
|
- `SystemBuilder` pattern for system construction
|
|
- `ThermoError` unified error handling
|
|
- All components implement serialization
|
|
|
|
From Story 6.4 (WebAssembly):
|
|
- JSON serialization pattern for results
|
|
- ConvergedState serialization approach
|
|
|
|
### Exit Code Convention
|
|
|
|
| Code | Meaning |
|
|
|------|---------|
|
|
| 0 | Success |
|
|
| 1 | Simulation error (non-convergence, validation failure) |
|
|
| 2 | Configuration error (invalid JSON, missing fields) |
|
|
| 3 | I/O error (file not found, permission denied) |
|

## Senior Developer Review (AI)
|
|
|
|
### Review Date: 2026-02-22
|
|
|
|
### Issues Found and Fixed
|
|
|
|
1. **[FIXED] HIGH - Solver strategy was ignored**: The `config.solver.strategy` field was parsed but not used. Now correctly uses `newton`, `picard`, or `fallback` based on config.
|
|
|
|
2. **[FIXED] MEDIUM - Edge validation incomplete**: Edge format validation checked `component:port` format but didn't verify component names exist. Now validates that all edge references point to existing components.
|
|
|
|
3. **[FIXED] MEDIUM - Example configs invalid**: Example configs contained `ExpansionValve` which requires connected ports and cannot be created via JSON config. Updated examples to use only supported components.
|
|
|
|
4. **[FIXED] LOW - Author hardcodé**: Changed from hardcoded author string to use clap's `#[command(author)]` which reads from Cargo.toml.
|
|
|
|
5. **[DOCUMENTED] Component Limitations**: `ExpansionValve` and `Compressor` require connected ports and are not supported in JSON configs. This is now clearly documented in README and error messages.
|
|
|
|
### Test Results
|
|
|
|
- All CLI lib tests pass (9 tests)
|
|
- Config parsing tests pass with new edge validation
|
|
- Batch execution tests pass
|
|
- Single run tests pass
|
|
|
|
### Recommendations for Future Work
|
|
|
|
- Add `Compressor` support with AHRI 540 coefficients
|
|
- Add `ExpansionValve` support with port auto-connection
|
|
- Add integration tests that execute actual simulations
|
|
- Consider recursive directory scanning for batch mode
