# E-scripts on Python.
#
# Note 1: use the eev command (defined in eev.el) and the
# ee alias (in my .zshrc) to execute parts of this file.
# Executing this file as a whole makes no sense.
# An introduction to eev can be found here:
#
#   (find-eev-quick-intro)
#   http://angg.twu.net/eev-intros/find-eev-quick-intro.html
#
# Note 2: be VERY careful and make sure you understand what
# you're doing.
#
# Note 3: If you use a shell other than zsh things like |&
# and the for loops may not work.
#
# Note 4: I always run as root.
#
# Note 5: some parts are too old and don't work anymore. Some
# never worked.
#
# Note 6: the definitions for the find-xxxfile commands are on my
# .emacs.
#
# Note 7: if you see a strange command check my .zshrc -- it may
# be defined there as a function or an alias.
#
# Note 8: the sections without dates are always older than the
# sections with dates.

Stephanie, vou te passar as anotacoes por aqui pra mais gente (Hugo,
por exemplo =) ) ter noção do que a gente está começando a
fazer...

Você instalou o Python(x,y) baixando isso aqui, né?
http://www.mirrorservice.org/sites/pythonxy.com/Python(x,y)-2.7.5.0.exe

E a gente tá tentando aprender a fazer computação
simbólica nele... quando eu rodo "isympy" no Linux as mensagens
são estas:

  IPython console for SymPy 0.7.1.rc1 (Python 2.7.3-32-bit) (ground types: python)
  These commands were executed:
  >>> from __future__ import division
  >>> from sympy import *
  >>> x, y, z, t = symbols('x y z t')
  >>> k, m, n = symbols('k m n', integer=True)
  >>> f, g, h = symbols('f g h', cls=Function)
  Documentation can be found at http://www.sympy.org
  In [1]: 

e aí a gente pode dar expressões como

  (1 - x) * 2

e o interpretador responde:

  -2*x + 2

porque ele trata isto como uma expressão (um polinômio)...
Estamos dando uma olhada neste tutorial e nestas páginas de referência,

  http://docs.sympy.org/0.7.2/tutorial.html
  http://docs.sympy.org/0.7.2/modules/core.html
  http://docs.sympy.org/0.7.2/modules/polys/reference.html

mas ainda não descobrimos um modo do Python pra Windows já
começar rodando os comandos que carregam o sympy e definem x, y, z,
t, etc como "expressões"...

.. usa o scipy.io para abrir o wav

se quiser uma lib mais porreta, tem a pysndobj e pyo

<edrx> can anyone recommend me an audio library for python in which
       I can play sounds and use the repl at the same time? for
       example, one in which I can read the value of
       nowplaying1.currentTime, and in which changing that value
       would make the player skip to another position...

<edrx> alguem pode me recomendar alguma biblioteca pra python na
       qual eu consiga tocar arquivos de audio e rodar a repl ao
       mesmo tempo?
<edrx> o que eu queria fazer era o seguinte: deem uma olhada em
       http://angg.twu.net/html5-audio.html - os links do final
       tocam um arquivo mp3 a partir de um certo ponto... e o
       player de audio roda em paralelo com o javascript console e
       com a parte do browser que interpreta cliques e outros
       eventos na pagina html renderizada...

<edrx> isto talvez seja uma pergunta boba, mas la vai...
<edrx> meu arquivo /tmp/in.wav parece ser um arquivo WAV todo
       certinho... acabei de cria-lo com ffmpeg a partir de um mp3,
       e "file /tmp/in.wav" diz isto:
<edrx>  /tmp/in.wav: RIFF (little-endian) data, WAVE audio,
       Microsoft PCM, 16 bit, stereo 44100 Hz
<edrx> mas ai' eu rodo isto...
<edrx> import scipy
<edrx> wavfile = "/tmp/in.wav"
<edrx> from scipy.io import wavfile as w
<edrx> amostras = w.read(wavfile)[1]
<edrx> e ganho:
<edrx>  /usr/lib/python2.7/dist-packages/scipy/io/wavfile.py:31:
       WavFileWarning: Unfamiliar format bytes
<edrx>   warnings.warn("Unfamiliar format bytes", WavFileWarning)
<edrx> e quando eu tento examinar o "amostras" ganho isto:
<edrx>  NameError: name 'amostras' is not defined
<edrx> (obs: se eu desconectar do canal e' so' porque o meu cliente
       de irc ta' mal configurado, nao porque eu desisti...)

<edrx> hi, I just downloaded the pip source from
       <https://github.com/pypa/pip> because I wanted to have a
       local copy of the docs, but I can't figure out how to
       compile it... I was expecting to be able to do something
       like "make docs", but it seems that it uses other tools...
       any hints?

Something that would output what it got from FB in a raw-ish form -
JSON? - would be ideal. Any hints welcome, as I am trying to write a
set of scripts for caching texts posted to FB that I may want to
access quickly later... the code that converts URLs to local file
names is ready - the URLs above are associated to files with these
names,

I would recommend that you chuck the obsolete os.popen() permanently and
learn the subprocess module: you will be much happier. Setting bufsize=0
(which is the default) should give you unbuffered output from the process.

NOTE: Debian testing (bullseye) has removed the "python" package and
the '/usr/bin/python' symlink due to the deprecation of Python 2. No
packaged scripts should depend on the existence of '/usr/bin/python':
if they do, that is a bug that should be reported to Debian. You can
use the 'python-is-python3' or 'python-is-python2' packages to restore
an appropriate '/usr/bin/python' symlink for third-party or legacy
scripts.
