It's cool but needs more information.

RodrigoEspinosa commented 8 years ago

It should be parsing the same information from node-exif but I'll take a look ;)

kud commented 8 years ago

Haha ;) okay.

oeuillot commented 8 years ago

Hello, We can integrate your cli command in the project. The package.json has a "bin" property to do that !

RodrigoEspinosa commented 8 years ago

@oeuillot Sounds good to me!

oeuillot commented 8 years ago

Ok I can integrate (copy) your code directly ?

RodrigoEspinosa commented 8 years ago

Sure you can :smiley: !

But... Maybe there is a better way to keep things synchronised. Like add it to the dependencies (haven't tried this but circular dependencies shouldn't be an issue anymore) or as a git submodule.

I'm fine by copying. Just wanted to mentioned another idea.

oeuillot commented 8 years ago

CLI has too many dependencies: i am worry about adding "commander" as dependency. I propose to continue to distinguish the lib and the cli.

RodrigoEspinosa commented 8 years ago

I think that's a good call :D

Libraries like commander or chalk have purpose on command line interfaces or related subjects. Given that node-exif works as an API I wouldn't see the point in adding them neither.

Idea: What if you point out the command line interface on the README for people who would like to try it and close this issue?

oeuillot commented 8 years ago

Good idea, I will add a link to the README !
