setting breakpoints from within python

[Steve Howell]

I am wondering if there is a way to set a pydev breakpoint programatically within python code.  Obviously, I generally set breakpoints through pydev itself, but there are two cases where I'd like to do it programatically.  

The first case is to debug django templates--I want to emulate this snippet, but in pydev:

http://www.djangosnippets.org/snippets/1550/

The second case is where you might have a long running loop and only want to start tracing at the 999th operation or when some condition is met, etc.

A quick Google search didn't turn up anything here, but I suspect there are docs on this somewhere, so if anyone can give me a pointer, it would be much appreciated.

I've been using PyDev for a couple months now--it's very helpful!

Cheers,

Steve

Yes, you can do that using:

import pydevd
pydevd.connected = True
pydevd.settrace()

Note that the pydevd.connected = True must be called only once (if you
don't do it, it'll think it has to connect to the remote debugger...
which is not what you want, unless you're actually using the remote
debugger). Note that you don't have to add pydevd to your pythonpath
(in a debug session it'll be there already without any special
setting).

Cheers,

Fabio
