This extension is used to allow adding modules in `nwbfile.acquisition`, similarly to how `nwbfile.processing` allows adding modules.

More specifically, this allows creating a module that has `TimeSeries` and `DynamicTable` objects, then users can add this module.

This is in alpha development stages. Please use with discretion.

[TOC]

## Requirement

The requirements and additional development requirements can be seen in [`pyproject.toml`](pyproject.toml) file.

Here are the minimum requirements:

- `python >=3.8`
- `pynwb>=1.5.0,<3`
- `hdmf>=3.4.7,<4`

## Installation

### Via `pip`

```bash
pip install ndx-acquisition-module
```

### Via `git`

```bash
pip install git+https://gitlab.com/fleischmann-lab/ndx/ndx-acquisition-module
```

## Usage

### Main usage

```python
from ndx_acquisition_module import AcquisitionModule

mod = AcquisitionModule(name="raw_mod", description="raw acq module")

# Add data objects to created AcquisitionModule
mod.add(time_series)  # add time series
mod.add(dynamic_table)  # add dynamic table

# Add AcquisitionModule to nwbfile.acquisition
nwbfile.add_acquisition(mod)
```

### Full example

```python
from datetime import datetime

import numpy as np
from dateutil import tz
from hdmf.common import DynamicTable, VectorData
from ndx_acquisition_module import AcquisitionModule

from pynwb import NWBHDF5IO, NWBFile, TimeSeries

# Create an example NWBFile
nwbfile = NWBFile(
  session_description="test session description",
  identifier="unique_identifier",
  session_start_time=datetime(2012, 2, 21, tzinfo=tz.gettz("US/Pacific")),
)

# Create time series
ts = TimeSeries(
  name="choice_series",
  description="raw choice series",
  data=np.random.randint(4, size=100),
  timestamps=(np.arange(100).astype("float") + 2) / 30,
  unit="-",
)

# Create dynamic table
tbl = DynamicTable(
  name="lookup_table",
  description="lookup table for `choice_series`",
  columns=[
    VectorData(
      name="lookup_id", description="ID to look up", data=[0, 1, 2, 3]
    ),
    VectorData(
      name="lookup_name",
      description="name of ID",
      data=["water", "earth", "fire", "air"],
    ),
  ],
)

# Create AcquisitionModule to store these objects
mod = AcquisitionModule(name="raw_mod", description="raw acq module")

# Add data objects to created AcquisitionModule
mod.add(ts)  # add time series
mod.add(tbl)  # add dynamic table

# Add AcquisitionModule to nwbfile.acquisition
nwbfile.add_acquisition(mod)

# Write the file to disk
filename = "test.nwb"
with NWBHDF5IO(path=filename, mode="w") as io:
  io.write(nwbfile)

```

### API usage notes

#### With package installed

Currently to use `mod.get(<object_name>)` or `mod[<object_name>]`, users would also need to install this package.

```bash
pip install git+https://gitlab.com/fleischmann-lab/ndx/ndx-acquisition-module
```

And import, using `NWBHDF5IO(..., load_namespaces=True)` would not be enough.

```python
# new file completely
from pynwb import  NWBHDF5IO
from ndx_acquisition_module import AcquisitionModule
nwb = NWBHDF5IO('test.nwb', mode='r').read() # notice `load_namepsaces` is not needed

print(nwb.acquisition['raw_mod'])
```

which outputs:

```text
raw_mod ndx_acquisition_module.AcquisitionModule at 0x139742592581104
Fields:
  data_interfaces: {
    choice_series <class 'pynwb.base.TimeSeries'>,
    lookup_table <class 'hdmf.common.table.DynamicTable'>
  }
```

To access:

```python
nwb.acquisition['raw_mod']['lookup_table']
nwb.acquisition['raw_mod']['choice_series']
```

#### Without package installed

Otherwise, if `ndx-acquisition-module` is not installed, accessing the inside objects have to be done based on types:

```python
# new file completely
from pynwb import  NWBHDF5IO
nwb = NWBHDF5IO('test.nwb', mode='r', load_namespaces=True).read() # notice `load_namepsaces` is NEEDED

print(nwb.acquisition['raw_mod'])
```

which outputs:

```text
raw_mod abc.AcquisitionModule at 0x140252603705728
Fields:
  description: raw acq module
  dynamic_tables: {
    lookup_table <class 'hdmf.common.table.DynamicTable'>
  }
  nwb_data_interfaces: {
    choice_series <class 'pynwb.base.TimeSeries'>
  }
```

To access:

```python
nwb.acquisition['raw_mod'].dynamic_tables['lookup_table']
nwb.acquisition['raw_mod'].nwb_data_interfaces['choice_series']
```

## TODOs

- [ ] Figure out how to allow consistent access even if package is not installed, so that using `load_namespaces=True` is sufficient.
- [ ] Edit `sphinx` deploy stage
- [x] Publish on `pypi`
- [ ] Publish on `conda`
