# Jekyll Processor
## Purpose
Builds Jekyll static sites by running `jekyll build` in directories containing
a `_config.yml` file.
## How It Works
Discovers `_config.yml` files in the project (excluding common build tool
directories). For each one, runs `jekyll build` in that directory.
## Source Files
- Input: `**/_config.yml`
- Output: none (creator)
## Configuration
```toml
[processor.jekyll]
args = []
dep_inputs = []
```
| `args` | string[] | `[]` | Extra arguments passed to jekyll build |
| `dep_inputs` | string[] | `[]` | Extra files whose changes trigger rebuilds |
## Batch support
Runs as a single whole-project operation (e.g., `cargo build`, `npm install`).
## Clean behavior
This processor is a Creator — `rsconstruct clean outputs` removes its declared `output_dirs` recursively (the build tool produces an unknown set of files inside, so directory-level deletion is the only option). After all per-product cleans complete, the orchestrator removes any parent directories that are now empty. Pass `--no-empty-dirs` to keep them. See [Clean behavior](../processors.md#clean-behavior) and [`rsconstruct clean`](../commands.md#rsconstruct-clean).
