Line information for [`ruamel.yaml`](https://pypi.org/project/ruamel.yaml/).

## Quick Start

### Using an Alternative Constructor

Instead of:

```python
with open(yaml_path, encoding="utf-8") as fh:
    yaml = ruamel.yaml.YAML(typ="rt").load("".join(fh))
```

change the import:

```python
with open(yaml_path, encoding="utf-8") as fh:
    yaml = ruamel_yaml_line_info.YAML(typ="rt").load("".join(fh))
```

and voila!

### Example

Consider the following YAML:

```yaml
foo: bar
block: >
  this is not
  a multiline
  block
single_quote: 'single'
double_quote: "double"
```

then we can get line and column information with

```python
>>> with open(yaml_path, encoding="utf-8") as fh:
    yaml = ruamel_yaml_line_info.YAML(typ="rt").load("".join(fh))
>>> print(yaml["foo"].lc)
LineCol(0, 5)
>>> print(yaml["block"].lc)
LineCol(1, 7)
>>> print(yaml["single_quote"].lc)
LineCol(5, 14)
>>> print(yaml["double_quote"].lc)
LineCol(6, 14)
```

where the first value in `LineCol` is the 0-based line, and the second value in `LineCol` is the 0-based column.

See the test for more exapmles.

### Patching an existing YAML object

If you already have a `ruamel.yaml.YAML` instance, you can add line
numbers with:

```python
with open(yaml_path, encoding="utf-8") as fh:
    yaml = ruamel.yaml.YAML(typ="rt").load("".join(fh))
    yaml = ruamel_yaml_line_info.YAML.with_line_numbers(yaml=yaml)
```

## Recommended Installation

Install the Python package and dependency management tool [`poetry`](https://python-poetry.org/docs/#installation) using official documentation.
You must have Python 3.11 or greater available on your system path, which could be managed by [`mamba`](https://mamba.readthedocs.io/en/latest/installation/mamba-installation.html), [`pyenv`](https://github.com/pyenv/pyenv), or another package manager. 
Finally, install the dependencies of the project with:

```console
poetry install
```

To check successful installation, run:

```console
python -c "import ruamel_yaml_line_info"
```

## Installing with Conda

Install the environment manager [`mamba`](https://mamba.readthedocs.io/en/latest/installation/mamba-installation.html) using official documentation.
Create and activate a conda environment with Python 3.11 or greater:

```console
mamba create -c conda-forge -n ruamel_yaml_line_info ruamel-yaml-line-info python=3.11
mamba activate ruamel_yaml_line_info
```

Alternatively, install into an existing conda environment:

```console
mamba install -n <ENVIRONMENT> -c conda-forge ruamel-yaml-line-info
```

To check successful installation, run:

```console
python -c "import ruamel_yaml_line_info"
```
