Question

I am trying to write some python code using tornado. Here is my code.

import sys
import tornado.ioloop
import tornado.web
import constants

class student():
    name = ""

class MainHandler(tornado.web.RequestHandler):
    def get(self):
        loader = tornado.template.Loader(".")
        print "MainiiiHandler"
        self.write(loader.load("base.html").generate(pics=constants.pics))

application = tornado.web.Application([
    (r"/", MainHandler),
])

if __name__ == "__main__":
    application.listen(8888)
    tornado.ioloop.IOLoop.instance().start()

So when i visit 127.0.0.1:8888, it should print MainiiiHandler in terminal. When i run python code with ‘python test.py’, it turns out actually like this. But when i run with :make in vim, it won’t print MainiiiHandler. Because i really like the make function in vim, so can you help me solve this problem.

Answer 1

Check how

makeprg is python %

is written.

:set makeprg="python %"

does NOT work for me (echoes an empty string)
while

:set makeprg=python\ %

actually DOES work.

(if it doesn’t help) This is what :h make shows:

The program given with the ‘makeprg’ option is started (default “make”) with the optional [arguments] and the output is saved in the errorfile (for Unix it is also echoed on the screen).

If your system is not Unix, I suppose you have to supply the code that will print the contents of errorfile for you (don’t know for sure as I tested it only under Linux).
