Compatibility with Flask

[MagnusOxlund]

I've been trying to use watch with Flask, but the output doesn't appear in the terminal until after the Flask application has terminated.

from watchpoints import watch
from flask import Flask

app = Flask('app')

x = None
watch(x)

@app.route('/')
def change_x():
	global x
	x = "Something"		# no output until after app.run terminates
	print("manual print")	# prints immediately
	return x

app.run('0.0.0.0', 500, debug=True, use_reloader=True)

Is there a way to output immediately?

Ah, that's actually a bug for watchpoints. watchpoints does not deal with global variables well. Also I'll have to be honest that this library has not been actively maintained. Personally I loved this black magic library but not there are not a lot of active users to make maintenance worthy.

I'm surprised to hear that. I can't imagine a better way to monitor variables that are involved in a complex interaction. Personally, I'm dealing with cached quasi-global proxy objects and hooks or signals being accessed by external modules I'm still getting to know. It can take quite a while to track down issues.

I only just discovered your project yesterday. Hopefully it will garner more attention and catch on.
