<!-- GETTING STARTED -->
## Getting Started

### Installation

To install, use your favorite package manager and do the equivalent of:

```sh
pip install versification-utils
```

<!-- USAGE EXAMPLES -->
### Usage

`versification-utils` provides three main functions: `detect`, `remap_verses`, and `to_vref`.

#### Detecting Versification

The `detect` function analyzes a list of verse references and returns the versification system that best fits the references. The function returns a string with the name of the versification system (or a list of versification schemas, if there was a tie).

```python
from versification_utils import detect

detect(["JHN 3:16", "JHN 3:17", "JHN 3:18"])
# ['eng', 'rsc', 'rso', 'vul', 'org', 'lxx', 'unk']
```

The schemas are abbreviated as follows:
- `eng`: English (Protestant)
- `rsc`: Russian (Synodal)
- `rso`: Russian (Orthodox)
- `vul`: Vulgate
- `org`: Original (Hebrew/Greek)
- `lxx`: Septuagint
- `unk`: Unknown

In this case, the verse references were insufficient to rule out any possibilities. But if we add more references, we can narrow down possibilities:

```python
detect(["PSA 22:31", "PSA 23:6"])
# 'eng'

detect(["PSA 22:32", "PSA 23:6"])
# 'org'
```

Only the `eng` versification system ends Psalms 22 with v. 31 and 23 with v. 6. So the first example returns `'eng'`, while the second example returns `'org'`. Technically, the diagnostics only examine the the last verse number of each chapter right now. This may change in future, so the `detect` function expects a list of USFM verse references. You should just pass in all the references you have (which would make for a convoluted example here).

#### Remapping Verses

If you know the versification schema your references follow, you can use the `remap_verses` function to convert them to another schema. This function takes a dictionary of verses that map the reference to the verse text, and returns a new dictionary with modified (remapped) references.

```python
from versification_utils import remap_verses

verses = {
    "PSA 22:31": "The last verse of Psalm 22",
    "PSA 23:6": "The last verse of Psalm 23"
}

from_schema = "eng"
to_schema = "org"
new_verses = remap_verses(verses, from_schema, to_schema)
# {'PSA 22:32': 'The last verse of Psalm 22', 'PSA 23:6': 'The last verse of Psalm 23'}

from_schema = "eng"
to_schema = "lxx"
new_verses = remap_verses(verses, "eng", "lxx")
# {'PSA 21:32': 'The last verse of Psalm 22', 'PSA 22:6': 'The last verse of Psalm 23'}
```

**Note:** In the second example, the LXX chapters are offset by one.

#### Exporting a Vref File

If you have a dictionary of verses, you can export them to a vref file using the `to_vref` function. This function takes a target `filename`, dictionary of `verses` (like the `remap_verses` function), and the `versification` schema of the verses. If the verses are not in `org` versification, `to_vref` will remap them to `org` before exporting.

```python
from versification_utils import to_vref

verses = {
    "PSA 22:31": "The last verse of Psalm 22",
    "PSA 23:6": "The last verse of Psalm 23"
}

to_vref("eng-my_translation.vref", verses, "eng")
# The vref file "./eng-my_translation.vref" will be created
```
