컬러 텍스트로 터미널에 pexpect 스크립트를 실행하는 방법

Question

Pexpect는 대화 형 세션에서 실행할 때 제대로 작동하지만 색상이있는 텍스트가 텍스트에만 일치하지 않으면 ansi 색상과 함께 텍스트가 일치합니다. 이를위한 정규식은 매우 복잡하고 크다. 누군가가 나에게이 작업 방법을 제안 할 수 있습니까? 예를 들어

는 :

"opendaylight 사용자 @ 루트"

이 찾고 : 단지에 대한

대신 찾고

'또는'\ x1b [1mlogout \ x1b [0m '종료 OpenDaylight. \ r \ r \ n \ r \ n \ x1b. \ r \ r \ n
\ r \ n \ x1b [36mopendaylight-user \ x1b [0m \ x1b [1m @ \ x1b [0m \ x1b [34mroot \ x1b [0m> ".

이것은 표현식의 일부일뿐입니다.

import pexpect 
import os 
def ex1(): 
     os.chdir("opendaylight/distribution-karaf-0.3.4-Lithium-SR4/bin/") 
     child=pexpect.spawn("./karaf clean",cwd="/home/ubuntu/opendaylight/distribution-karaf-0.3.4-Lithium-SR4/bin/") 
     child.expect("opendaylight-user@root>") 
     print child.before 
ex1()

Answer 1

내가 expect_exact를 사용하여 대답을 얻었다() 기대보다는(). expect()는 정규식과 일치하지만 expect_exact는 문자열과 일치합니다.

import pexpect 
    import os 
    def ex1(): 
     os.chdir("opendaylight/distribution-karaf-0.3.4-Lithium-SR4/bin/") 
     child=pexpect.spawn("./karaf clean",cwd="/home/ubuntu/opendaylight/distribution-karaf-0.3.4-Lithium-SR4/bin/") 
     child.expect_exact("\x1b[36mopendaylight-user\x1b[0m\x1b[1m@\x1b[0m\x1b[34mroot\x1b[0m>") 
     print child.before 
    ex1()
