About pydollar
--------------
`pydollar <https://github.com/bjodah/pydollar>`_ is a `Python <https://www.python.org>`_ module
which enables a non-native syntax for the dollar sign ``$`` in Python code. It allows you to
follow the DRY-principle (don't repeat yourself) more stricly when writing python code:

Take for example a file called ``mymodule.py``:

.. code:: python

   from sympy import Symbol

   def my_func():
       alpha, beta, gamma, delta, epsilon = symbs = map(Symbol, $)
       return symbs

we could then import from it by first intalling an import hook:

.. code:: python

   >>> import pydollar
   >>> pydollar.install_import_hook()
   >>> from mymodule import my_func
   >>> from sympy import init_printing
   >>> init_printing()
   >>> my_func()
   (α, β, γ, δ, ε)

    
Motivation
----------
f-strings were a great additon to Python 3.6, the ``$`` syntax follows it in spirit,
it simply allows you to write succinct code.

If ``$`` syntax (or more importantly, the functionality it provides) becomes official syntax
there would be a real-world benefit to widely used codebases, e.g. SymPy:

https://github.com/sympy/sympy/blob/sympy-1.0/sympy/core/symbol.py#L587


Installation
------------
Simplest way to install pydollar is to use ``pip``::
  
   $ python3 -m pip install --user pydollar

you can skip the ``--user`` flag if you have got root permissions.
