show 1.1.1

Debug print statements, done right. E.g. show(x)

from show import *

x = 12
nums = list(range(4))

show(x, nums)

yields:

x: 12  nums: [0, 1, 2, 3]

Output is self-labeled, so you don’t spend time doing that yourself.

Debug Printing

Logging, assertions, unit tests, and interactive debuggers are all great tools. But sometimes you just need to print values as a program runs to see what’s going on. Every language has features to print text, but they’re rarely customized for printing debugging information. show is. It provides a simple, DRY mechanism to “show what’s going on.”

Sometimes programs print so that users can see things, and sometimes they print so that develpopers can. show() is for developers, helping rapidly print the current state of variables in ways that easily indentify what value is being printed, without a lot of wasted effort. It replaces the craptastic repetitiveness of:

print "x: {0}".format(x)

with:

show(x)

If you’d like to see where the data is being produced,:

show.set(where=True)

will turn on location reporting. This can also be set on call-by-call basis.

You can also easily distinguish your debugging information from all of the normal program output. For example:

show.say.set(style='green')

Will print all of your debugging information in, you guessed it, green.

For this and much more, see the full documentation at Read the Docs.

Note

There are known issues about running this on Python 2.6 and 3.5, and on Windows.
