## Test cases

Both parser and serializer are tested [on more than 1000 example files.](https://github.com/laszlokorte/renewex/tree/main/test/fixtures/valid_files)

### Running tests

All test:
```sh
mix test
```

Only fast tests:
```sh
mix test --exclude slow
```

## Example Usage

```example.ex
# Read rnw file
{:ok, file_content} = File.read("example.rnw")

# Parse file content
{:ok, %Renewex.Document{} = document} = Renewex.parse_document(file_content)

# Inspect document:
IO.puts(document.version)
IO.puts(document.root)
IO.puts(Enum.count(document.refs))

# Do some work with `document`
# ...

# serialize document back into string
{:ok, serialized} = Renewex.serialize_document(document)

# Write rnw file
File.write("modified.rnw", serialized)
```
