--save-dev also copy "dependencies" into "devDependencies" about ied

[zhuangya]

i only expected to save debug of coures

Yeah, had a look into it. This is actually not a bug, but more or less the intended behaviour, which might be confusing.... and I'm open to changes here..

• ied install installs all dependencies and devDependencies from package.json
• ied install some-package installs only some-package
• ied install some-package --save installs only some-package and saves it under dependencies
• ied install some-package --save-dev installs only some-package and saves it under devDependencies
• ied install --save installs all dependencies and devDependencies from package.json and saves them under dependencies
• ied install --save-dev installs all dependencies and devDependencies from package.json and saves them under devDependencies

etc.

Confusing cases:

• ied install --save-dev some-package installs all dependencies and devDependencies from package.json and saves them under devDependencies, some-package is being ignored and is not being installed

etc.

To put it in a nutshell the order matters. ied install debug --save-dev does what you would expect.

maybe the option order should matter, or should not

but can you write this in document?

it's pretty confusing to many people i think

Can we make the behaviour of the basic commands as similar to npms behaviour as possible?

If you need a rationalisation, mine is that ied [command] [--modifier] [subject(s)] makes it more obvious that the modifier (e.g. --save-dev) is upon the command (e.g. install). Basically, it should be this way for the same reason you don't ied [subject(s)] [command] (e.g. ied debug install).

It's confusing that option order should matter, most reasonably friendly CLI tooling doesn't require this. These cases should be interchangeable:

• ied install --save foo
• ied install foo --save

The --save option is "tied" to the install command, not the argument foo. At least, that's how I'm used to thinking about the UX of CLI tooling.

This has been fixed.
