Update JS files for the libraries

[Shekharrajak]

Developers can update the js files using these command in the repo:

rake library_name:update

e.g. rake highcharts:update

To update all the JS files : rake update_all

But how user will update it (who have installed the gem from the source or using gem install) ?

Probably we can have CLI and using command daur-view update_js library_name user can update the particular js . I like the way Thor gem works. But there is some other good Command Line Interface Gems as well.

I think we should use ARGV because the gem is less likely to get CLI intensive in future. WDYT?

ping! @Shekharrajak I would like to take up this issue

[Shekharrajak]

@rohitner , sorry for late response! Yes , we didn't think much about CLI in daru-view. But to update the js files, calling method don't look a good choice to me. I am not sure about it. Can you light more on your idea?

@zverok , what do you think?

[Shekharrajak]

@rohitner , meanwhile you can open PR with your idea.

[rohitner]

We can also make use of optparse module like that being done by the gem colorls (although Thor has advantages like seperate parsers for different commands). I think OptionParse class will be most appropriate at this point.

I am not sure what do you mean, can you please elaborate?

[rohitner]

I mean to say that using pre-installed modules like optparse are enough for supporting a few command line arguments rather than adding third-party dependencies like Thor.
