Why does this Ruby statement throw an exception? (Arrays/Bools) -


I'm not a Ruby man, I just play one on television. I have to modify some old chron job to pull some Jason down and turn into objects.

Here is the code 

  raw_json = Net :: HTTP.get (URI parsing ("URL is removed to protect innocent")) Tags = ActiveSupport: JSON .decode (raw_json) tags.count

detects tag.count 5 correctly, but that line is immediately the reason for the crash: 

  5 # Counts right! Rack abortion! Undefined method for false `count ': FalseClass

What is the dealerio?

What is the content of raw_json ? What seems to be happening is that returning ActiveSupport :: JSON # decode (hence the undefined method is false for 'fault': FalseClass ). I think that JSON # decode returns false if only given empty string, which means that HTTP # get is returning an empty string raw_json < Check / code> and see what is expected in it.

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
