DSN can be provided via `--dsn` flag or `DSN` env var (from `.env` file).
**Modes:**
- **Interactive (default)**: select tables with fzf
- **Batch (`--filter` or `--all`)**: generate matching tables with confirmation
| Flag | Default | Description |
|----------|------------------------|--------------------------------------------------|
| `--dsn` | *(from DSN env)* | MySQL/MariaDB DSN, e.g. `user:pass@tcp(localhost:3306)/dbname` |
| `--filter` | `(ps_|b2b_).*` | Regex matching table names to generate |
| `--filter` | *(interactive)* | Regex matching table names to generate (triggers batch mode) |
| `--all` | *(interactive)* | Generate all tables matching filter (shows confirmation) |
| `--out` | `./app/model/dbmodel` | Output directory for generated files |
| `--pkg` | `dbmodel` | Go package name for generated files |

### Generate All Tables
### Batch Mode (--filter)
Use `--all` to generate all tables matching the filter:
Use `--filter` to generate all tables matching a regex pattern:
```bash
gormcol-gen --dsn "user:pass@tcp(localhost:3306)/mydb" --all
gormcol --dsn "user:pass@tcp(localhost:3306)/mydb" --filter "ps_product.*"
```
### Generate All Tables (--all)
Use `--all` to generate all tables matching the default filter `(ps_|b2b_).*`:
```bash
gormcol --dsn "user:pass@tcp(localhost:3306)/mydb" --all

./gormcol --dsn "user:pass@tcp(localhost:3306)/mydb" --filter "ps_.*" --out ./internal/model --pkg model
```
This connects to the database, generates a `.go` model file for each matching table, and appends `<Model>Cols` variables with typed `gormcol.Field` descriptors to each file.
