        "description": "ipython_ferretmagic\n===================\n\nIPython notebook extension for ferret (a great software for Data Visualisation and Analysis from NOAA/PMEL).\n\nBrowse the demo notebooks from http://nbviewer.ipython.org/github/PBrockmann/ipython_ferretmagic/tree/master/notebooks\n\nCombine ferret and ipython widgets and create interactive notebooks !\n\nTest it with binder.\n[![Binder](https://mybinder.org/badge.svg)](https://mybinder.org/v2/gh/PBrockmann/ipython_ferretmagic/master)\n\nBrowse a basic ferret tutorial using ferretmagic from: https://github.com/PBrockmann/C-CASCADES_notebooks/blob/master/ferretBasics.ipynb\n\n![ScreenShot](./images/ferretmagic_widgets.png)\n\n## Latest news \n\n2018/10/01\n * Compatibility with python 3 with print command and base64 encoding\n * Tested with pyferret==7.43, notebook==5.7.0, jupyter==1.0.0, ipython==5.8.0, ipywidgets==7.4.2\n * Update pip package (now last version is 20181001 https://pypi.org/project/ferretmagic/)\n\n2018/01/18\n * a Docker image is available from https://hub.docker.com/r/pbrockmann/pyferret-7.3/\n * pyferret 7.3 and ferretmagic extension can now be fully tested from binder (http://mybinder.readthedocs.io/en/latest) !\n * Tested with pyferret==7.3, jupyter==4.4.0, ipython==5.5.0, ipywidgets==7.0.5\n\n2017/03/17\n * Tested with pyferret==7.1, jupyter==4.2.0, ipywidgets==6.0.0\n\n2016/10/28\n * Tested with pyferret==7.0, jupyter==4.2.0 and ipython==5.1.0\n * Installation from pip\n\n## Installation\n\nInstall PyFerret following instructions from http://ferret.pmel.noaa.gov/Ferret/documentation/pyferret\nIt will set all directories needed to run pyferret (font, ppl, jnls, datasets, ...).\n\nYou can also install PyFerret as a conda package from https://anaconda.org/conda-forge/pyferret (no datasets distributed).\n\nThen install the ferret magic extension (ferretmagic.py) by typing\n```pip install ferretmagic```\n\n## Usage\n\nIn a Jupyter notebook with kernel python (previously named ipython), load the magics:\n\n    In [2]: %load_ext ferretmagic\n\n### Line magics\n\nThe `%ferret_run` magic enables one-line execution of ferret command in the IPython interpreter or notebook:\n\n```\n    In [3]: for i in [100,500,1000]:\n      ....: \t%ferret_run -s 400,400 'plot sin(i[i=1:%(i)s]*0.1)' % locals()\n```\n\n### Cell magics\n\nMulti-line input can be entered with the `%%ferret` cell magic:\n\n```\nIn [4]: %%ferret\n  ....: use levitus_climatology\n  ....: shade temp[k=1]\t\t\t! comments\n```\n\n* Control size of plot with --size, -s option.\n* Create a local pdf at the same time with --pdf, -p option.\n\n```\nIn [5]: %%ferret -s 400,300 -pdf myfig.pdf\n  ....: shade temp[k=1]\t\t\t\n```\n\n### Passing variables between Python and ferret \n\n* Variables can be pushed from IPython into ferret with `%ferret_putdata`:\n\n```\nIn [18]: %%ferret\n   ....: use levitus_climatology\nIn [19]: %ferret_getdata tempdict = temp\n   ....: Message: tempdict is now available in python as a dictionary containing the variable's metadata and data array.\nIn [20]: print tempdict.keys()\n   ....: ['axis_coords', 'axis_types', 'data_unit', 'axis_units', 'title', 'axis_names', 'missing_value', 'data']\n```\n\n* Variables can be pulled from ferret into IPython with `%ferret_getdata`:\n\n```\nIn [31]: import numpy as np\n   ....: b = {}\n   ....: b['name']='myvar'\n   ....: b['name']='myvar'\n   ....: x=np.linspace(-np.pi*4, np.pi*4, 500)\n   ....: b['data']=np.sin(x)/x\n   ....: b.keys()\nOut[31]: ['data', 'name']\nIn [32]: %ferret_putdata --axis_pos (1,0,2,3,4,5) b\n   ....: Message: b is now available in ferret as myvar\n```\n\nExplore notebook for examples.\n\n## Known issues and limitations\n\n* Note that the pdf file produced by -p,--pdf option is not embedded in the notebook\n* Limitations are the ones exposed from pyferret, the qualifier /pattern is not usable for example.
