Send Message

$ qslack send --help
Usage: qslack send [OPTIONS] MESSAGE

  Send message to the channel

Options:
  -m, --mention            If use this flag, mention default mention
                           user/groups

  -c, --channel-name TEXT  Channel name to send message, use default channel
                           in config if not passed

  --help                   Show this message and exit.

You can send message by using qslack send command.

$ qslack send hi
Error occured in sending message!
{'ok': False, 'error': 'invalid_auth', 'warning': 'missing_charset', 'response_metadata': {'warnings': ['missing_charset']}}

If the token is incorrect, the above error may occur.

qslack send hi
Error occured in sending message!
{'ok': False, 'error': 'not_in_channel', 'warning': 'missing_charset', 'response_metadata': {'warnings': ['missing_charset']}}

• Bot must be added to the channel to send a message. If not, may result in errors such as 'not_in_channel' or 'channel_not_found'.
• If an error occurs, it is related to the slack API, so if you enter the token incorrectly or miss the permission setting, you should set the token properly and add the missing permission.

Send a message based on command results

qslack cond --help
Usage: qslack cond [OPTIONS] COMMAND

  Run command and send message based on whether success command

Options:
  -s, --success TEXT  Message sent if command success
  -f, --fail TEXT     Message sent if command failed
  -m, --mention       If use this flag, mention default mention users
  --help              Show this message and exit.

• The command above is to send a message based on the results of the command. If exit code is 0, send the message of success argument and if not, send the message of failure argument.
• If you have not set up a message, do not send a message.

$ qslack cond pwd -s hi -f hello
/Users/psj8252/quick-slack
Command success
Sending message is done.

For example, if the pwd command is successful, sends a message 'hi'.

qslack cond 'bash -c "exit 1"' -f good
Command exit with 1
Sending message is done.

In the above case, send the message 'good' because the exit code failed to 1.

  -b, --backgroud        Run this command backgroud
  --help                 Show this message and exit.

  -n, --interaval FLOAT  seconds to wait between checking liveness
  --help                 Show this message and exit.

$ qslack ifend 18103 "end end"
