crates csv anonymizer app

csv-anonymizer-app

Active contributors: Douwe de Vries

Purpose

csv-anonymizer-app is the lightweight CLI binary and smoke harness for the shared Rust core. It is not the Tauri desktop app UI; it exists to exercise csv-anonymizer-core from a command-line entry point.

Directory layout

Path	Role
crates/csv-anonymizer-app/src/cli.rs	CLI action enum, argument parsing, command execution, and help text.
crates/csv-anonymizer-app/src/main.rs	Process entry point that prints help/version or runs a parsed action.
crates/csv-anonymizer-app/Cargo.toml	Binary crate metadata and path dependency on csv-anonymizer-core.

Key abstractions

• CliAction describes supported actions: help, version, analyze, smoke anonymize, and anonymize.
• parse_cli_args handles platform-specific startup noise, flags, positional arguments, and column parsing.
• run_cli creates AnonymizerService and calls shared core APIs.
• --smoke-anonymize analyzes input, auto-selects sensitive columns with should_auto_select_column, previews samples, then writes output with force: true.
• The binary name is csv-anonymizer, configured in the crate Cargo.toml.

How it works

    participant Shell as CLI process

    Runner-->>Shell: stdout or error

Loading

The CLI intentionally keeps behavior thin. Analysis prints row count and per-column detector output. Anonymization passes selected column indexes directly to the core. The smoke path proves that analysis, preview, auto-selection, and output writing work together without going through Tauri or React.

Integration points

• csv-anonymizer-core provides all domain behavior.
• Root scripts such as node scripts/rust-smoke.mjs can use the CLI smoke path.
• Release tooling references this crate for smoke validation and legacy native macOS packaging paths.
• Workspace checks include this crate through cargo test --workspace, cargo check --workspace, and cargo clippy --workspace --all-targets.

Entry points for modification

• Change supported CLI commands or flags in crates/csv-anonymizer-app/src/cli.rs.
• Change process-level error handling or entry behavior in crates/csv-anonymizer-app/src/main.rs.
• Change binary metadata or dependencies in crates/csv-anonymizer-app/Cargo.toml.
• Prefer adding shared behavior to csv-anonymizer-core instead of duplicating it in the CLI.
