Any way to send text with newlines with signal-cli?

[garryadkins]

I'd like to be able to send messages with newline characters in them. The formatting would make them easier to read.

Is there any way to do this? Passing \n doesn't seem to work.

Thanks!

If typing a message on the command line, press Enter inside an un-closed quote:

signal-cli send +1234567890 -m 'multi  <Press Enter here>
line message'

In bash it's also possible to put \n chars inside the $'string's:

signal-cli send +1234567890 -m $'multi\nline'

Any help on doing this on Windows?

Do not seem to get it to work with the above in a powershell nor cmd.
A '^' to simulate the Enter press inside an un-closed quote won't work either, nor do the options in #105.
The '\n' is simply sent in plain text within the message, or "Failed to send message: No valid characters found." is returned.

I got this to work in Linux by passing ~ to the script and in python changing that to a carriage return. It works perfectly for me now on a Raspberry Pi. I could NOT seem to pass it a newline, it just always sent \n no matter how I massaged it. That's why I used ~ instead. Not sure what language you're using but here's teh relevant code I use in python. #Now we split on ~ so we can create newline chars in string. #For some reason we can't seem to parse \n properly # incoming_msg[0] is the text of the message. #Here we split it and recombine to add newlines if they exist. message_text_raw=str(incoming_msg[0]).split('~') for i in message_text_raw: message_text_w_newline= message_text_w_newline + "\n" + i # Add a newline and the current date and time #message_text_w_newline= message_text_w_newline + "\n\n**********\nSent:\n" + datetime.now().strftime('%H:%M:%S\n%m-%d-%Y') message_text_w_newline= message_text_w_newline + "\n\n**********\nSent:\n" + datetime.now().strftime('%m-%d-%Y\n%H:%M:%S') incoming_msg[0]=message_text_w_newline Hope this helps.

Thanks for the swift reply.

Yes using python as well.

That still does not do the job though...

What is the incoming_msg datatype and how are you sending the message? I only receive the message before the newline character, so in the below example i receive: This is

I am calling:

from datetime import datetime

now = datetime.now() # current date and time

incoming_msg = 'Also~part~of~the~test'
message_text_raw=str(incoming_msg).split('~')

message_text_w_newline = str('This is \n a test')
for i in message_text_raw:
message_text_w_newline= message_text_w_newline + "\n" + i

`# Add a newline and the current date and time`

message_text_w_newline= message_text_w_newline + "\n\n**********\nSent:\n" + now.strftime('%m-%d-%Y\n%H:%M:%S')

incoming_msg=message_text_w_newline

I then call some functions to compile the command (" ".join etc.) and print the command:

cli_arg = signal-cli -u +xxxxxxxx send +xxxxxxxx -m "This is
a test
Also
part
of
the
test
`**********` `Sent:` `08-15-2021` `20:45:51"`
feedback = subprocess.Popen(cli_arg,shell=True, stdout=subprocess.PIPE)

I am receiving the message from a MQTT broker. The incoming_message is an object with several different things like topic, payload, qos and retain flags. payload is the actual message I'm interested in. The incoming message is a comma delimited list of things, so I split it into an array based on the comma: It is cast to a str (see the code below) message_text_raw contains a long string with ~ chars instead of newlines. They are converted to \n and placed into the string message_text_w_newline. This is what I pass to signal_cli Here's the example code: #Incoming message should have *"message to send", phone1, phone2, *etc. #We split this message into a list so we can append to the signal_msg above incoming_msg=*str*(msg.payload).split(',') #Now we split on ~ so we can create newline chars in string. #For some reason we can't seem to parse \n properly *# incoming_msg[0] is the text of the message.* #Here we split it and recombine to add newlines if they exist. message_text_raw=str(incoming_msg[0]).split('~') for i in message_text_raw: message_text_w_newline= message_text_w_newline + "\n" + i I run the signal command line (again this is unix, not sure if this will work in windows) # Run as a subprocess so we can fork and continue subprocess.Popen(signal_msg) signal_msg just has the command line parms to signal_cli #This is a test message known to work. (signal sender ends with 6666 and the recipient ends with 7777) # This just sends the message "test" #signal_msg = ["/usr/local/bin/signal-cli", "-u","+12225556666", "send", "-m", "test", "+12225557777"] You would obviously replace "test" with the string that you create. Here's what one of the messages sent by this method looks like: Door Battery Report Kitchen: 100% Front: 65% Pool: 6% 2nd Guest: 73% ********** Sent: 08-14-2021 17:59:59 And the received message looks like this before parsing: topic/signal_message=Door Battery Report~~Kitchen: 100%:~Front: 65%~Pool: 6%~2nd Guest:73%,+12225557777 This string is parsed and replaced ~ with \n as you can see in the message above. Door Battery Report~~Kitchen: 100%:~Front: 65%~Pool: 6%~2nd Guest:73%
