可听错误 - 用于Python日志记录模块的自定义非阻塞文本到语音处理程序

我正在构建一个基于Raspberry Pi的无屏幕长期艺术装置。 Text-to-Speech on the Raspberry pi的一个常见应用是人们配置他们的Pis在启动时说出他们的IP地址以简化SSH。

我已经爱上了日志记录模块。永远不再评论无数的印刷陈述让我的心发光。对于我的情况,有一个说出错误消息的日志记录处理程序是理想的。我目前使用的StreamHandler和FileHandler非常适合开发和问题后诊断,但对于原位问题解决却很糟糕。此外,有一些令人愉快的SciFi关于我的机器人在向我大喊大叫错误。

I found an example of a custom handler for SMS-based error logging,并尝试通过电子发言实现我自己。它说话,但整个节目在第一个口语句末结束时停止。

我正在寻找有关如何实现不阻止程序执行的流处理程序的建议。 我破坏的自定义处理程序:

import logging
import os

#based on SMSHandler http://pantburk.info/?blog=77

def speak(stringToSay):
    '''say whatver it is told to say, squleching annoying warnings'''
    stringToSay = "'"+stringToSay+"'"
#English female voice, emphasis on capitals (-k), speaking slowly (-s) using direct text:-
#the 2>/dev/null' is there because any calls to the rPi audio card result in a dozen warnings.
#  see: http://raspberrypi.stackexchange.com/questions/3412/errors-with-espeak
    os.system('espeak  -ven+f3 -k5 -s150 '+stringToSay+' 2>/dev/null')

class TALKHandler(logging.Handler): # Inherit from logging.Handler
        def __init__(self):
                # run the regular Handler __init__
                logging.Handler.__init__(self)
        def emit(self, record):
                # record.message is the log message
                speak(record.message)

正在记录的程序的代码段

logging.handlers.TALKHandler = speechHandler.TALKHandler
# create the handler object
talkingHandler = logging.handlers.TALKHandler()
# Configure the handler to only send SMS for critical errors
talkingHandler.setLevel(logging.CRITICAL)
# and finally we add the handler to the logging object
logger.addHandler(talkingHandler)

ipAddress = [(s.connect(('8.8.8.8', 80)), s.getsockname()[0], s.close()) for s in [socket.socket(socket.AF_INET, socket.SOCK_DGRAM)]][0][1]
ipAddress = " ".join(ipAddress)
ipAddress = ipAddress.replace(".","dot")
logger.critical("Current IP Address is " + ipAddress  )

我知道这是在很久以前就被问过了 - 我在发布时错过了它并偶然发现了它。以下适用于我:

import logging
import subprocess
import sys

class TalkHandler(logging.Handler):
    def emit(self, record):
        msg = self.format(record)
        cmd = ['espeak', '-ven+f3', '-s150', msg]
        p = subprocess.Popen(cmd, stdout=subprocess.PIPE,
                             stderr=subprocess.STDOUT)
        p.communicate()

def configure_logging():
    h = TalkHandler()
    root = logging.getLogger()
    root.addHandler(h)
    root.setLevel(logging.DEBUG)

def main():
    logging.info('Hello')
    logging.debug('Goodbye')

if __name__ == '__main__':
    configure_logging()
    sys.exit(main())

当我跑步时,我听到“你好”,然后说“再见”。
