Add a function to tell the weather of today to slack bot (made by python)

What to do in this article

If you ask the bot "What's the weather today?", I will tell you the weather today as follows.

Mounting method

The implementation is very easy, I will use the command created by the following person and return the result from the bot. [Code to quote]

curl -s https://weather.yahoo.co.jp/weather/jp/40/8210/40133/8100001.html | tr '\n' ' ' | sed -e 's/<[^>]*>//g' | grep -oE ' - [0-9].*tomorrow' | tr ' ' '\n' | grep -v ^$ | head -47 | tr '\n' '\t' | awk '{sub("time", "\ntime ");sub("weather", "\nweather ");sub("Temperature (℃)", "\nTemperature (℃)");sub("Humidity (%)", "\nHumidity (%)");sub("Precipitation (mm/h）", "\nPrecipitation (mm/h）");print}'

One line to get and display the weather forecast with Linux command

We will add functions to the python bot created below [Add conversation function to slack bot (made by python) using Recruit's Talk API](http://qiita.com/takahirono7/items/197375db24a03cbcd591#%E3%81%93%E3%81%AE%E8 % A8% 98% E4% BA% 8B% E3% 81% A7% E3% 82% 84% E3% 82% 8B% E3% 81% 93% E3% 81% A8)

File structure and directory

Create a new directory and file with a star. Take the route from my_mention.py to hit the modular confirm_weather.py

slackbot         #A directory that organizes programs. Any name is fine
├─ run.py        #Start the bot by running this program
├─ slackbot_settings.py   #File to write settings related to bot
└─ plugins                #Add bot functionality to this directory
   ├─ __init__.py         #A file to indicate the module. Sky is fine
   └─ my_mention.py       #Features each file. Any name is fine
★   └─ scripts           #script storage directory
★   　　　　├─ confirm_weather.py     #Script to get the weather information this time
★   　　　　├─ confirm_today_weather.sh     #A script that contains the curl command
★   　　　　├─__init__.py

The current my_mention.py should look like this:

# coding: utf-8

from slackbot.bot import respond_to     # @botname:Decoder that reacts with
from slackbot.bot import listen_to      #Decoder that responds to in-channel remarks
from slackbot.bot import default_reply  #Decoder that reacts when there is no corresponding response

# @respond_to('string')Message to bot
#string can be a regular expression "r'string'」
# @listen_to('string')Posts other than to bots in the channel
#                           @botname:Note that it does not react
#React when mentioning to others
#Regular expression possible
# @default_reply()          DEFAULT_Same function as REPLY
#If you specify a regular expression, it will not hit other decoders,
#Reacts when matching a regular expression
#... But is it an error if I specify a regular expression?

# message.reply('string')   @Speaker name:Send message with string
# message.send('string')Send string
# message.react('icon_emoji')Reaction to the speaker's message(stamp)To do
#In the string':'I don't need
@respond_to('Mention')
def mention_func(message):
    message.reply('What do you do when you say mention to me') #Mention

@listen_to('Listen')
def listen_func(message):
    message.send('Someone seems to have posted with listen')      #Just a post
    message.reply('You?')                           #Mention

import pya3rt
@default_reply()
def send_message(message):
    apikey = "XXXXXXXXXXXXXXXXXXXXXXX"
    client = pya3rt.TalkClient(apikey)
    reply_message = client.talk(message.body['text'])
#Since json is returned in the following format, take out the reply part
# {'status': 0, 'message': 'ok', 'results': [{'perplexity': 1.2802554542585969, 'reply': 'I'm not sure'}]}
    message.reply(reply_message['results'][0]['reply'] + "Pome" )

I will add the following code here

from plugins.scripts.confirm_weather import ConfirmWeather
#A function that tells you the weather today
@respond_to('(^.*today.*weather.*)')
def confirm_today_weather(message, something):
    weather_class = ConfirmWeather()
    weather_class.return_today_weather(message)

It's okay to write the code in my_mention.py, but it will be long, so I will specialize the function that my_mention.py has for post-reservation registration and module calling. The actual confirmation code is described in confirm_weather.py and confirm_today_weather.sh under scripts.

confirm_weather.py

import json
import subprocess
import os


class ConfirmWeather():

    def __init__(self):
    pass

    def return_today_weather(self, message):
#Get the path where this script is located
        script_dir = os.path.abspath(os.path.dirname(__file__))
        cmd = os.path.join(script_dir, "confirm_today_weather.sh")
#Store the execution result of the shell script placed in the same directory in a variable
        weather_info = subprocess.check_output(cmd)
        print(weather_info.decode('utf-8'))
#POST to slack
        message.send("I'll tell you the weather today")
        message.send(weather_info)

The following points are important: The execution result of the shell script in the same directory is stored in a variable using the check_output method of the subprocess module.

#Store the execution result of the shell script placed in the same directory in a variable
        weather_info = subprocess.check_output(cmd)

confirm_today_weather.sh The one-liner command quoted at the beginning is stored in the same directory as a shell script file as shown below.

-Give execution permission with chmod 755 -Modularize __init__.py in the same directory Don't forget

curl -s https://weather.yahoo.co.jp/weather/jp/40/8210/40133/8100001.html | tr '\n' ' ' | sed -e 's/<[^>]*>//g' | grep -oE ' - [0-9].*tomorrow' | tr ' ' '\n' | grep -v ^$ | head -47 | tr '\n' '\t' | awk '{sub("time", "\ntime ");sub("weather", "\nweather ");sub("Temperature (℃)", "\nTemperature (℃)");sub("Humidity (%)", "\nHumidity (%)");sub("Precipitation (mm/h）", "\nPrecipitation (mm/h）");print}'

Run the bot with python run.py, what's the weather today? If you talk to the bot, the result at the beginning will come back.
