Excellent Script works well, how to send pictures .jpg's ... ? is there a way?

I can't get it to work! I'm copying the code from gist and pasting it into a shell file then using chmod u+x on the file but I can't use the iMessage command

I had to comment out line 42 "close window 1". Still working on the sending it to myself portion. My contact info is in my contacts.

Edit: Same as @zbholman.

works like a charm in Sierra. thx.

i keep getting a execution error: Messages got an error: Can’t get buddy id "E166DC77-8136-4C98-B7EC-F153B020E6D0:+15555555555". (-1728)

(replaced phone number with 5s)

@jaredmichaelwilliams did you find a fix?

@jaredmichaelwilliams and possibly @briangonzalez I got this error by using the wrong service. If you're trying to send an SMS, the two lines,

set targetBuddy to buddy targetBuddyPhone of service "SMS"
send targetMessage to targetBuddy

will work, rather than writing

set targetService to 1st service whose service type = "SMS"

before those two lines, which I also got that error for.

All AppleScript solutions I've seen only seem to work with phone numbers that you have existing conversations with and are a contact 😞

Yeah, for the buddy id error, you need to have an existing conversation first!

For the Messages got an error: Can’t get buddy id ... error Is there any way to create a buddy id without manually messaging first?

I tried importing a CSV into Contacts.app, which I thought would work, but... nope.

I just got a bunch of people join a meetup I co-organize and was hoping to not have to message all of the new ones individually before sending reminders.

Here's how to send messages without manually creating a buddy:

#!/bin/sh
if [ "$#" -eq 1 ]; then stdinmsg=$(cat); fi
exec <"$0" || exit; read v; read v; read v; exec /usr/bin/osascript - "$@" "$stdinmsg"; exit

on run {phoneNumber, message}
    activate application "Messages"
    tell application "System Events" to tell process "Messages"
        key code 45 using command down -- press Command + N to start a new window
        keystroke phoneNumber -- input the phone number
        key code 36 -- press Enter to focus on the message area 
        keystroke message -- type some message
        key code 36 -- press Enter to send
    end tell
end run

Thanks for this. Is there a way to do this without having the iMessage window popup and display on the desktop?

I get error "966:967: syntax error: Expected expression, etc. but found unknown token. (-2741)" what does this mean ? thanks

Can you help me send photo through iMessage ? I tried this code but it show "Failed to send" after few minutes of waiting

set theAttachment1 to POSIX file "/path to file/test.png"
send file theAttachment1 to targetBuddy

Is there a way to keystroke a Group chat instead of a phone number?
