Maximum recursion depth exceed for "learn.aiml" examples

[mertyildiran]

Hey @cdwfs , thanks for this great library!

I'm facing with a problem while trying to use these learn.aiml files with your library. Mitsuku: http://www.square-bear.co.uk/aiml/learn.zip ALICE: http://alicebot.wikidot.com/learn-aiml

It's trapping in to an infinite loop, how can I solve that? This is the error.log from the beginning to KeyboardInterrupt.

stderr:

KeyboardInterrupt

With these usage attempts both of them has same problem:

import aiml

kernel = aiml.Kernel()
kernel.learn("learn.aiml")
print kernel.respond("Learn the sun is hot")

import aiml

kernel = aiml.Kernel()
sessionId = 12345
kernel.getSessionData(sessionId)
kernel.learn("learn.aiml")
print kernel.respond("Learn the sun is hot")

Hi Mehmet -- glad you like pyaiml! Unfortunately I really haven't been actively maintaining the module for many many years. I'll do my best to investigate this issue when I have a chance, but at this point your guess may be as good as mine.

OK I will try to fix then. If I will be successful, I will send a pull request for this issue. Thanks for the reply. :+1:

hey friend i have developed support for learn tag i don't know how to make pull request can i share code here

[mertyildiran]

@athuldevin please read Creating a pull request from a fork.

[athuldevin]

https://github.com/athuldevin/learn

the complete pyaiml files and learn.aiml is available here i have made changes to parser and kernel from pyaiml 0.9.0 changes made

ability to save bot predicates which set dynamically and restore also added learn tag changed previous learn to load added eval tag

problem if bot learn something to brain there is a problem in debugging output, not in response

also developed support for javascript tag but not included in this kernel because it require one additional package , if you like i will share
