```

#### Defaults

- Filetypes: `{ "yaml", "json" }`
- Method: `diagnostics`
- Command: `cfn-lint`
- Args: `{ "--format", "parseable" }`

#### Notes

- Once a supported file type is opened null-ls will try and determine if the file looks like an AWS Cloudformation template.
- A file will be considered an AWS Cloudformation template if it contains a "Resources" or "AWSTemplateFormatVersion" key.
- To prevent cfn-lint running on all YAML and JSON files that contain a "Resources" key.
- The file must contain at least one AWS Cloudformation Resource Type, e.g "Type": "AWS::S3::Bucket"
- This check will run only once when entering the buffer.
- This means if "Resources" or "AWSTemplateFormatVersion" is added to a file after this check is run, the cfn-lint diagnostics will not be generated.
- To fix this you must restart Neovim.

### [checkmake](https://github.com/mrtazz/checkmake)

#### Usage

```lua

```

#### Defaults

- Filetypes: `{ "java" }`
- Method: `diagnostics_on_save`
- Command: `checkstyle`
- Args: `{ "-f", "sarif", "$ROOT" }`

#### Notes

- Checkstyle only offers a jar file as download. It is recommended to put an executable wrapper script in
your path.
Example wrapper script:
```bash
#!/usr/bin/env bash
java -jar path/to/checkstyle.jar "$@"
```
- Checkstyle needs a mandatory `-c` argument. Use `extra_args` to add yours. `extra_args` can also be a
function to build more sophisticated logic.

- Method: `diagnostics_on_save`
- Command: `clazy-standalone`
- Args: `{ "--ignore-included-files", "--header-filter=$ROOT/.*", "$FILENAME" }`

#### Notes

- `clazy` needs a compilation database (`compile_commands.json`) to work. By default `clazy` will search for a compilation database in all parent folders of the input file.
- If the compilation database is not in a parent folder, the `-p` option can be used to point to the corresponding folder (e.g. the projects build directory):
```lua
local sources = {
    null_ls.builtins.diagnostics.clazy.with({
        extra_args = { "-p=$ROOT/build" },
    }),
}
```
- Alternatively, `compile_commands.json` can be linked into the project's root directory. For more information see https://clang.llvm.org/docs/HowToSetupToolingForLLVM.html
- `clazy` will be run only when files are saved to disk, so that `compile_commands.json` can be used.
