Contributing
============
Before submitting pull requests please make sure your code complies with the following.
Git etiquette
-------------
If you're planning on adding a feature (new function or class) then create your own branch,
```bash
$ git checkout -b my_new_feature
```
and start commiting there to test and work on. We will follow a [trunk-based development model](https://youtu.be/ykZbBD-CmP8). This means we will rapidly merge branches once you have something stable and continue with master branch. So make sure to push something stable instead of being in your feature branch for too long. I will try to address your pull request ASAP.
[![Trunk-based Development](http://img.youtube.com/vi/ykZbBD-CmP8/0.jpg)](https://www.youtube.com/watch?v=ykZbBD-CmP8 "Trunk-based Development")
Coding Style: PEP 8
-------------------
The style for your code must follow the [PEP 8](https://www.python.org/dev/peps/pep-0008/) style guide. It would be helpful to use a linter like [pylint](https://pylint.org) to check whether your code is complying before submitting.
```bash
$ pylint somefile.py
```
Coding Standard
---------------
Please write readable code. Make sure your function names well describes your functions. Always include docstrings that use the [Google coding style](http://google.github.io/styleguide/pyguide.html#381-docstrings). The Google coding style guide is a good document to follow so I recommend reading it.
Metadata
--------
Include metadata if you made a new function or module. Name and email will suffice. Use the variable names `__author__` and `__email__` for modules and comments for functions that you add to someone else's module. For example:
mynewpackage.py:
```python
"""A new package for swmfpy
"""
__all__ = ['funcs', 'to', 'export']
__author__ = 'Rita Hayworth'
__email__ = 'rita@umich.edu'
```
Or for a function:
```python
def my_new_func(some_args):
"""my docstring
"""
# Author: Diane Selwyn
# Email: diane@umich.edu
# function body
```
Dependencies
------------
If your code has dependencies that is large and uncommon (e.g. SpacePy) then please import it in the function and be explicit about the dependencies. For example you may create a function:
```python
def func_with_dependency():
"""Func does this.
Depends on spacepy. Try `pip install -U spacepy`
"""
import spacepy
# Function body
```
Then your functions will be in swmfpy.spacepy which has its own namespace.
Modules
-------
If you want to create a new module make sure what you're trying to do can't just fit in the modules already made.

These are automatically imported.
- `swmfpy.io` Input/Output tools.
- `swmfpy.paramin` PARAM.in editing tools.
- `swmfpy.web` Internet data downloading/uploading tools.
### Extra Modules
These are not automatically imported. Might have extra dependancies.
*None yet.*
<a name=".swmfpy.write_imf_from_omni"></a>
#### write\_imf\_from\_omni
```python
write_imf_from_omni(time_from, time_to, filename='IMF.dat', **kwargs)
```
Writes an IMF.dat file for the geospace model runs for a specific time
period.

- `time_to` _datetime.datetime_ - Time to end omni data retrieval
- `filename` _str_ - The filename for the dat file, defaults to 'IMF.dat'.
**kwargs:
see `swmfpy.io.write_imf_input()` and `swmfpy.web.get_omni_data()`
**Examples**:
Using this function is simple:

# Sometimes this
swmfpy.write_imf_input(*times, filename='run/IMF.dat')
```
<a name=".swmfpy.web"></a>
## swmfpy.web
### Tools to download/upload data on the web
Here are a collection of tools to work with data on the internet. Thus,
this module mostly requires an internet connection. Which on some
supercomputers would be turned off during a job run. In scripts, make sure to
use these to preprocess before submitting jobs.
<a name=".swmfpy.web.get_omni_data"></a>
#### get\_omni\_data
```python
get_omni_data(time_from, time_to, **kwargs)
```
Retrieve omni solar wind data over http.
This will download omni data from https://spdf.gsfc.nasa.gov/pub/data/omni
and put it into a dictionary. If your data is large, then make a csv and
use swmfpy.io.read_omni_data().
**Arguments**:
- `time_from` _datetime.datetime_ - The start time of the solar wind
data that you want to receive.
- `time_to` _datetime.datetime_ - The end time of the solar wind data
you want to receive.
**kwargs:
- `original_colnames` _bool_ - Use the original column names from the
spdf specification. The alternative is
nicer and shorter names. Defaults to
False.
- `resolution` _str_ - (default: 'high') Here you can choose 'high' or
'low' resolution omni data. Some columns appear
in one but not the other.
**Returns**:
- `dict` - This will be a list of *all* columns
available in the omni data set.
**Examples**:
```python
import datetime
import swmfpy.web
storm_start = datetime.datetime(year=2000, month=1, day=1)
storm_end = datetime.datetime(year=2000, month=2, day=15)
data = swmfpy.web.get_omni_data(time_from=storm_start,
time_to=storm_end)
# or for low res
data = swmfpy.web.get_omni_data(time_from=storm_start,
time_to=storm_end,
resolution='low')
```
<a name=".swmfpy.web.download_magnetogram_hmi"></a>
#### download\_magnetogram\_hmi
```python
download_magnetogram_hmi(mag_time, hmi_map='hmi.B_720s', **kwargs)
```
Downloads HMI vector magnetogram fits files.
This will download vector magnetogram FITS files from
Joint Science Operations Center (JSOC) near a certain hour.
This unfortunately depends on sunpy and drms, if you don't have it try,
```bash
pip install -U --user sunpy drms
```
**Arguments**:
- `mag_time` _datetime.datetime_ - Time after which to find
vector magnetograms.
- `hmi_map` _str_ - JSOC prefix for hmi maps. Currently can only do
'hmi.B_720s' and 'hmi.b_synoptic.small'.
**kwargs:
- `download_dir` _str_ - Relative directory to download to.
- `verbose` _bool_ - (default False) print out the files it's downloading.
**Returns**:
- `str` - list of filenames downloaded.
**Raises**:
- `ImportError` - If module `drms` is not found.
- `FileNotFoundError` - If the JSOC doesn't have the magnetograms for that
time.
**Examples**:
```python
from swmfpy.web import download_magnetogram_hmi
import datetime as dt
# I am interested in the hmi vector magnetogram from 2014, 2, 18
time_mag = dt.datetime(2014, 2, 18, 10) # Around hour 10
# Calling it will download
filenames = download_magnetogram_hmi(mag_time=time_mag,
hmi_map='B_720s',
download_dir='mydir/')
# To see my list
print('The magnetograms I downloaded are:', filenames)
# You may call and ignore the file list
download_magnetogram_hmi(mag_time=time_mag,
hmi_map='b_synoptic_small',
download_dir='mydir')
```
<a name=".swmfpy.web.download_magnetogram_adapt"></a>
#### download\_magnetogram\_adapt
```python
download_magnetogram_adapt(time, map_type='fixed', **kwargs)
```
This routine downloads GONG ADAPT magnetograms.
Downloads ADAPT magnetograms from ftp://gong2.nso.edu/adapt/maps/gong/
to a local directory. It will download all maps with the regex file
pattern: adapt4[0,1]3*yyyymmddhh
**Arguments**:
- `time` _datetime.datetime_ - Time in which you want the magnetogram.
- `map_type` _str_ - (default: 'fixed')
Choose either 'fixed' or 'central' for
the map type you want.
**kwargs:
- `download_dir` _str_ - (default is current dir) Relative directory
where you want the maps to be downloaded.
**Returns**:
- `str` - First unzipped filename found.
**Raises**:

is not found on the server.
- `ValueError` - If map_type is not recognized.
(i.e. not 'fixed' or 'central')
- `FileNotFoundError` - If maps were not found.
**Examples**:
```python
import datetime as dt
# Use datetime objects for the time
time_flare = dt.datetime(2018, 2, 12, hour=10)
swmfpy.web.download_magnetogram_adapt(time=time_flare,
map_type='central',
download_dir='./mymaps/')
```
<a name=".swmfpy.io"></a>
## swmfpy.io
### Input/Output tools
Here are tools to read and write files relating to SWMF.
<a name=".swmfpy.io.write_imf_input"></a>
#### write\_imf\_input
```python
write_imf_input(imf_data, filename='IMF.dat', **kwargs)
```
Creates the IMF.dat input file for the SWMF BATS-R-US geospace model.
`imf_data` must be a dictionary of array_like objects with same length
in data. In swmfpy Pythonic versions are always preferred so the 'times'
must be `datetime.datetime` array.
imf_data = dict(times, bx, by, bz, vx, vy, vz, density, temperature)
**Arguments**:
- `imf_data` _dict_ - This dictionary contains the solar wind data.
- `filename` _str_ - (default: 'IMF.dat') Filename to write to.

- `TypeError` - If commands is not a list or tuple. It must be at least a
one element list of strings.
- `AssertionError` - If inputs aren't prepared properly (key names)
**Examples**:
```python
from swmfpy.io import write_imf_input

<a name=".swmfpy.io.read_wdc_ae"></a>
#### read\_wdc\_ae
```python
read_wdc_ae(wdc_filename)
```
Read an auroral electrojet (AE) indeces from Kyoto's World Data Center
text file into a dictionary of lists.
**Arguments**:
- `wdc_filename` _str_ - Filename of wdc data from
http://wdc.kugi.kyoto-u.ac.jp/
**Returns**:
- `dict` - Auroral indeces 'AL', 'AE', 'AO', 'AU'
- `datetime.datetime` - 'times'
- `int` - 'values'
<a name=".swmfpy.io.read_wdc_asy_sym"></a>
#### read\_wdc\_asy\_sym
```python
read_wdc_asy_sym(wdc_filename)
```
Reads a WDC file for ASY/SYM data.
Reads an ASY/SYM file downloaded from
http://wdc.kugi.kyoto-u.ac.jp/aeasy/index.html
and puts it into a dictionary.
**Arguments**:
- `wdc_filename` _str_ - Relative filename (or file handle no.) to read.
**Returns**:
- `dict` - of values. {'[ASY-SYM]-[D-H]': 'times': [], 'values': []}
**Examples**:
```python
indeces = swmfpy.io.read_wdc_asy_sym('wdc.dat')
# Plot data
plt.plot(indeces['SYM-H']['times'],
indeces['SYM-H']['values'],
label='SYM-H [nT]'
)
plt.xlabel('Time [UT]')
```
Important to note if there is bad data it will be filled as None.
<a name=".swmfpy.io.read_gm_log"></a>
#### read\_gm\_log
```python
read_gm_log(filename, colnames=None, dtypes=None, index_time=True)
```
Make a dictionary out of the indeces outputted
from the GM model log.
**Arguments**:
- `filename` _str_ - The relative filename as a string. (or file handle no.)
- `colnames` _[str]_ - (default: None) Supply the name of the columns.
If None it will use second line
of log file.
- `dtypes` _[types]_ - (default: None) Provide types for the columns, if
None then all will be float.
- `index_time` _bool_ - (default: True) Make a column of dt.datetime objects
in dictionary key 'Time [UT]'.
**Returns**:
- `dict` - Dictionary of the log file
**Examples**:
To plot AL and Dst get the log files
```python
geo = swmfpy.io.read_gm_log('run/GM/IO2/geoindex_e20140215-100500.log')
dst = swmfpy.io.read_gm_log('run/GM/IO2/log_e20140215-100500.log')
# Plot AL indeces
plt.plot(geo['times', geo['AL'])
```

### Editing PARAM.in files
These tools are to help script the editing and reading of PARAM.in files.
<a name=".swmfpy.paramin.replace_command"></a>
#### replace\_command
```python
replace_command(parameters, input_file, output_file='PARAM.in')
```
Replace values for the parameters in a PARAM.in file.
Note, if you have repeat commands this will replace all the repeats.
**Arguments**:
- `parameters` _dict_ - Dictionary of strs with format
replace = '#COMMAND': ['value', 'comments', ...]
This is case sensitive.
- `input_file` _str_ - String of PARAM.in file name.
- `output_file` _str_ - (default 'PARAM.in') The output file to write to.
A value of None will not output a file.
**Returns**:
A list of lines of the PARAM.in file that would be outputted.
**Raises**:
- `TypeError` - If a value given couldn't be converted to string.
**Examples**:
```python
change['#SOLARWINDFILE'] = [['T', 'UseSolarWindFile'],
['new_imf.dat', 'NameSolarWindFile']]
# This will overwrite PARAM.in
swmfpy.paramin.replace('PARAM.in.template', change)
