Spawn NOENT on windows

[pflannery]

Because node on windows needs to specify the .cmd extension when were using spawn then commands like chainy install common fail with spawn NOENT during lines like this

if we parsed all chainy-plugin-exec command lines (windows only) with a regexp that extends the first word to include .cmd then maybe we can work around with minimal fuss.

@balupton something similar to this?

command = command.replace(/^([\\\/.:\w\-]+)/ig, "$&.cmd");

[pflannery]

then something like this would go here

if (process.platform === 'win32') {
    value = value.replace(/^([\\\/.:\w\-]+)/ig, "$&.cmd");
}

doing this get chainy install common working on my windows instance.

Yeah, we should use bevry/safeps for this, it'll handle it automatically.

[balupton]

actually, exec plugin already uses safeps... so we need to find out why safeps wasn't fixing this for us...
https://github.com/chainy-plugins/exec/blob/master/lib/exec.js#L4

perhaps it's because we are giving it one string instead of an array

[balupton]

this is where it should work:

doh I didnt see your last two comments until now. It maybe because of the opts.safe not being true in the exec plugin?

I made a pr but it looks like it should handle it just not triggering ?
bevry/safeps#5

Looking deeper I see opts.safe is set to true by default.

The real reason is because the exec path provided by chainy-cli is using absolute path which is avoided by safeps here
