# fallow config

> Show the resolved fallow config and which file was loaded. Mirrors eslint --print-config and dprint output-resolved-config.

Print the resolved configuration and the path of the config file that was loaded. Useful for debugging "why isn't my config being applied?" especially in monorepos where multiple `.fallowrc.json` files may be in play.

```bash theme={null}
fallow config
```

By default, prints the loaded config path on the first line followed by the JSON-serialized config (with `extends` resolved):

```text title="$ fallow config" theme={null}
loaded config: /repo/.fallowrc.json
{
  "entry": ["src/main.ts"],
  "ignorePatterns": ["dist/**"],
  "duplicates": {
    "ignoreImports": true
  },
  ...
}
```

## Options

| Flag     | Description                                                                               |
| :------- | :---------------------------------------------------------------------------------------- |
| `--path` | Print only the config file path, one line, no JSON. Easier to consume from shell scripts. |

The global `--config <path>` flag is honored: if you pass it, that path is loaded directly instead of walking the directory tree.

## Exit codes

| Code | Meaning                                                         |
| :--- | :-------------------------------------------------------------- |
| `0`  | A config file was found and loaded                              |
| `2`  | Error (failed to parse, explicit `--config` path missing, etc.) |
| `3`  | No config file was found; defaults are in effect                |

## Examples

### Verify which config the LSP/CLI picked up

In a monorepo, when running fallow from inside a sub-package:

```bash theme={null}
cd packages/app
fallow config --path
# /repo/.fallowrc.json   (root config inherited — sub-package has none of its own)
```

If a sub-package has its own config, that path is printed instead (first-match-wins).

### Use an explicit config file

```bash theme={null}
fallow --config ./my-config.json config
```

### Pipe to jq for further inspection

```bash theme={null}
fallow config | tail -n +2 | jq '.duplicates'
```

The first line (`loaded config: ...`) is on stdout above the JSON, so `tail -n +2` skips it.

### Detect "no config" in scripts

```bash theme={null}
if ! fallow config --path > /tmp/fallow-cfg-path 2>/dev/null; then
  echo "no fallow config found, will use defaults"
fi
```
