oelint-adv 1.1.0

Advanced bitbake-recipe linter

# oelint-adv
Advanced oelint

## Purpose

Based on the [OpenEmbedded Styleguide](https://www.openembedded.org/wiki/Styleguide) and work done by [oe-stylize-tool](https://github.com/openembedded/meta-openembedded/blob/master/contrib/oe-stylize.py) this module offers a (nearly) complete linter for bitbake-recipes.

The tool does handle includes/requires automatically so you don't have to pass them via CLI.

## Usage

```
python3 oelint_adv -h
usage: oelint_adv [-h] [--suppress SUPPRESS] [--output OUTPUT]
files [files ...]

Advanced OELint - Check bitbake recipes against OECore styleguide

positional arguments:
files File to parse

optional arguments:
-h, --help show this help message and exit
--suppress SUPPRESS Rules to suppress
--output OUTPUT Where to flush the findings (default: stderr)
```

## Output

Will be [file]:[line]:[severity]:[message].

Example:
```
