> Grapheme-to-Phoneme transductions that preserve input and output indices!

This library is for handling arbitrary transductions between input and output segments while preserving indices.

## Background

The initial version of this package was developed by [Patrick Littell](https://github.com/littell) and was developed in order to allow for g2p from community orthographies to IPA and back again in [ReadAlong-Studio](https://github.com/dhdaines/ReadAlong-Studio). We decided to then pull out the g2p mechanism from [Convertextract](https://github.com/roedoejet/convertextract) which allows transducer relations to be declared in CSV files, and turn it into its own library - here it is!

## Install

The best thing to do is install with pip `pip install g2p`. 

Otherwise, clone the repo and pip install it locally.

```sh
$ git clone https://github.com/roedoejet/g2p.git
$ cd g2p
$ pip install -e .
```

## Usage

In order to initialize a `Transducer`, you must first create a `Mapping` object.

### Mapping

You can create mappings either by initializing them directly with a list:

```python
from g2p.mappings import Mapping

mappings = Mapping([{"in": 'a', "out": 'b'}])

```

Alternatively, you can add a CSV file to g2p/mappings/langs/`<YourLang>`/`<YourLookupTable>`

```python
from g2p.mappings import Mapping

mappings = Mapping(language={"lang": "<YourLang>", "table": "<YourLookupTable>"})

```

### Transducer

Initialize a `Transducer` with a `Mapping` object. Calling the `Transducer` then produces the output. In order to preserve the indices, pass index=True when calling the `Transducer`.

```python
from g2p.mappings import Mapping
from g2p.transducer import Transducer

mappings = Mapping([{"in": 'a', "out": 'b'}])
transducer = Transducer(mappings)
transducer('a')
# 'b'
transducer('a', index=True)
# ('b', <g2p.transducer.indices.Indices object>)

```

To make sense of the `Indices` object that is produced, you can either call it, and produce a list of each character. Doing that for the above produces `[((0, 'a'), (0, 'b'))]` - a list of relation tuples where each relation tuple is comprised of an input and output. Each input tuple and output tuple is in turn comprised of an index and a corresponding character. You can also call `output()` and `input()` to see the plain text output and input respectively.

## Studio

You can also run the `g2p Studio` which is a web interface for creating custom lookup tables to be used with g2p. To run the `g2p Studio` either visit ***** or run it locally using `python run_studio.py`. 

You can also import the app directly from the package:

```python
from g2p import app

app.run(host='0.0.0.0', port=5000, debug=True)
```
