Backslash is printed when escaping double quotes in cmd

[Franklin88]

Test configuration:
{
"name": "Test escaping characters",
"cmd": "echo "Hello"; echo 'world'; "
}

Output:
$ echo "Hello"; echo 'world';
"Hello"
world

Expected:
$ echo "Hello"; echo 'world';
Hello
world

Notes:
Same result using unicode \u0022 => {"cmd": "echo \u0022Hello\u0022; echo 'world'; "}

Environment:
MacOS 10.10.5
Shuttle v1.2.7
iTerm2 Build 3.0.8
Terminal.app 2.5.3 (343.7)

What are you wanting to accomplish? It seems that its working as expected.
If I manually type in terminal echo \"Hello\" I get the expected output of "Hello"
I get this because I'm escaping the double quotes and they print.

If I manually type in terminal echo "Hello" I get the expected output of Hello
I get this because I'm Not escaping the double quotes so they don't print

Probably I'm not fully understanding how escaping works. Let me give you a real life example.
I want to run the following command: ps -ef | grep java | awk '{print "Pid: "$2, $8, $9, $10}'

If I insert this in the shuttle.json config file I have to escape the double quotes of the print part otherwise it breaks the config file, so my cmd looks like this: "cmd": "ps -ef | grep java | awk '{print \"Pid: \"$2, $8, $9, $10}'"

But when I execute this through shuttle it runs it with the backslashes breaking the actual command:

$ ps -ef | grep java | awk '{print \"Pid: \"$2, $8, $9, $10}'
awk: syntax error at source line 1
 context is
        {print >>>  \ <<< "Pid: \"$2, $8, $9, $10}
awk: illegal statement at source line 1

What am I doing wrong?

Btw, if I apply the same to the name tag it works like I would expect:

Name tag is configured as follows:
"name": "ps -ef | grep java | awk '{print \"Pid: \"$2, $8, $9, $10}'"

And in the menu it shows up without the backslashes:

ps -ef | grep java | awk '{print "Pid: "$2, $8, $9, $10}'

@Franklin88 Awesome, Thanks for the real world examples. I'll look into a solution.

@Franklin88 Seems that we have a bug with the way double quotes are escaped.
I'll have a fix for v1.2.8

Great! Thx

Not sure if this is the same issue or not, but I'm having an issue with wanting to use a backslash in my command and it not working. I try running it from the menu, and nothing happens (as soon as I remove the backslash, it works fine). It's the one right after "Mobile":

        {
            "name": "Run local site",
            "cmd": "cd /Users/myusername/Library/Mobile\\ Documents/com~apple~CloudDocs/Sites/mysitename && commandhere"
        }

I tried it with and without the double backslash, and neither works.

@WorldWideWebb I have confirmed that the bug is causing this issue as well. I'll try to have 1.2.8 for the weekend.

Anything new on this bug?

It's resolved on my dev system. Doing some more testing before I release. I can send you what I have if you want to test. Currently on Gitter if you want to chat there.
