pipe “less” content out, when “less” get content from stdin
Question
In "ipython", we use some_obj??
to get documentation, which uses "less" to show the docs. How can we get the document out of "less", into a text editor? The content is fed from stdin, so pressing "v" gives the error: "can not edit standard input"
Solution
some_obj??
is equivalent the built-in help
function. This is a wrapper around pydoc.help.
import pydoc
doc = pydoc.text.document(some_obj)
print doc
You may save the documentation to a file. Then open in a text editor.
