当我在交互式会话中运行Pexpect时,它可以正常工作,但是如果有彩色文本,则不仅匹配文本,而且还会匹配文本及其ansi颜色。这个正则表达式非常复杂和庞大。有人能建议我如何处理吗。
例如:
不仅查找:
"opendaylight-user@root"
还要查找:
"or '\x1b[1mlogout\x1b[0m' to shutdown 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>".
这只是表达式的一部分。
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()
错误
