Yowsup: Send breakLine through yowsup-cli

[Pedro-H-Fialho]

Tried using n, /n, n on message but didn't work.

Any suggestion?

Ive done it by replacing
def setBody(self, body):
self.body = body

with

def setBody(self, body):
self.body = body.replace("###","n")

in yowsup/layers/protocol_messages/protocolentities/message_text.py
so every ### in the message text will get replaced with n
i think it would also be prossible to do
.replace("n","n")
which replaced every n in the message text with a NewLine

thanks @dedmen. I fix using
def setBody(self, body):
self.body = body.replace("n","n")

No response when i change the file. i can make what ever i want.
setBody in "yowsup/layers/protocol_messages/protocolentities/message_text.py"

You don't need to modify yowsup's code. When sending a message, use:

mymessage.replace("n", "n")

thats not working anymore, any solution?

Looking too

My solution is not in setBody but in getBody :

# yowsup/layers/protocol_messages/protocolentities/message_text.py

def getBody(self):
    return self.body.replace("\n","\n")

The setBody will receive body as byte string if you replace then it will convert the object to str and it will be rejected.

I confirm that this dedmen code still works!

def setBody(self, body):
self.body = body.replace("###","n")

remove /usr/local/bin/yowsup-cli and recompile

#

not work,
self.body = body.replace("n","n")

Need to use double slash \n in setBody. but in the cli demo just use one slash. example as below

edit file yowsup/layers/protocol_messages/protocolentities/message_text.py

def setBody(self, body):
    #self.body = body
    self.body = body.replace("\\n","\n")

sudo python setup.py install

./yowsup-cli demos -y -d -c whatsapp_config.txt
/L
/message send 6012XXXXX "Testing 123\nThis text printed in new line\n and this as well"

@azizasm : it's works, thank you 👍✨

I encountered the same problem when using the cli on Bash.
I think the problem is Python argument parser will _escape_ the backslash passed in new line (n).
You can check a related Stackoverflow question:
https://stackoverflow.com/questions/34145686/handling-argparse-escaped-character-as-option

So an alternative solution, _without_ modifying the source code is to enclose the message in dollar sign and single quotes like so:
yowsup-cli demos --login [PHONE:PASSWORD] --send [DESTINATION] $'First Line\nSecond Line'

Notice that the message is enclosed in $'......', dollar sign then single quote. This will send a _literal_ new line character versus the default _escaped_ new line character.

A good fix may be to decode the string passed to the argument parser? Something like:
bytes(myStringWithEscapedNewLine, "utf-8").decode("unicode_escape")
