68 1. Documentation and usage
69 --------------------------
73 http://docs.sympy.org/
75 You can generate everything at the above site in your local copy of SymPy by:
79 $ epiphany _build/html/index.html
81 If you don't want to read that, here is a short usage:
83 From this directory, start python and:
84 >>> from sympy import Symbol, cos
87 >>> print e.series(x, 0, 10)
88 1 + (1/2)*x**2 + (5/24)*x**4 + (61/720)*x**6 + (277/8064)*x**8 + O(x**10)
90 SymPy also comes with a console that is a simple wrapper around the
91 classic python console (or ipython when available) that loads the
92 sympy namespace and executes some common commands for you.
98 from this directory if SymPy is not installed or simply
102 if SymPy is installed somewhere in your PATH.
108 to execute tests, run
112 in the current directory. You need to have py.test installed.
115 4. How to install py.test
116 -------------------------
118 If you use Debian, just install the python-codespeak-lib. Otherwise:
120 Execute in your home directory:
122 svn co http://codespeak.net/svn/py/dist py-dist
124 This will create a "py-dist" directory in you home dir. Add this line to
127 eval `python ~/py-dist/py/env.py`
129 Now you can call "py.test" from anywhere.
134 To clean everything (thus getting the same tree as in the svn):
142 SymPy was started by Ondrej Certik in 2005, he wrote some code during the
143 summer, then he wrote some more code during the summer 2006. In February 2007,
144 Fabian Seoane joined the project and helped fixed many things, contributed
145 documentation and made it alive again. 5 students (Mateusz Paprocki, Brian
146 Jorgensen, Jason Gedge, Robert Schwarz and Chris Wu) improved SymPy incredibly
147 during the summer 2007 as part of the Google Summer of Code. Pearu Peterson
148 joined the development during the summer 2007 and he has made SymPy much more
149 competitive by rewriting the core from scratch, that has made it from 10x to
150 100x faster. Jurjen N.E. Bos has contributed pretty printing and other patches.
151 Fredrik Johansson has wrote mpmath and contributed a lot of patches. Kirill
152 Smelkov has joined the development in autumn 2007 and has improved the overall
153 quality of SymPy a lot and is currently one of the most active developers.
