perl - What is the most efficient way to override an attribute in lots of my Moose based sub classes? -


I'm using it to be used to be a subclass and then you type field_name_space Or overwrite certain attributes like attribute_name_space .

However, now I have so many forms that extend the HTML :: FormHandler or its DBIC based version and therefore these super-bound properties have been repeated many times.

I tried to put them in a role but got an error which is not supported in roles + attr notation is sufficiently reasonable.

What is the best way to destroy this repetition? I thought maybe that is a subclass but then I have to do this twice for HTML :: FormHandler and HTML :: FormHandler :: Model :: DBIC , plus I believe That's the general thought that instead of subclassing is better received with better roles.

Update: I thought it would be a good idea to give an example. This is what I am currently doing - and it includes code repeat as you can see that a form uses a different parental class, so I did not create an original class to put the attribute override in. can. I have to make two- and also add redundancy too 

  package MyApp :: Form :: Foo; # This form does not interfere with DBIC 'HTML :: form handler'; '+ Html_prefix' = & gt; (Default => 1); Is' + fields_trats = = & gt; (Default = & gt; sub [[MyApp :: Form :: Trait :: Field ']}); '+ Field_name_space' = & gt; (Default = & gt; 'MyApp :: Form :: Field'); '+ Widget_name_space' = & gt; (Default = & gt; sub [[MyApp :: Form :: Widget ']}); '+ Widget_wrapper' = & gt; (Default = & gt; 'none'); ... package MyApp :: Form :: Bar; # This form uses the DBIC object 'HTML :: FormHalller :: Model :: DBIC'; '+ Html_prefix' = & gt; (Default => 1); Is' + fields_trats = = & gt; (Default = & gt; sub [[MyApp :: Form :: Trait :: Field ']}); '+ Field_name_space' = & gt; (Default = & gt; 'MyApp :: Form :: Field'); '+ Widget_name_space' = & gt; (Default = & gt; sub [[MyApp :: Form :: Widget ']}); '+ Widget_wrapper' = & gt; (Default = & gt; 'none'); ... package MyApp :: Form :: Baz; # This form also uses the DBIC object 'HTML :: FormHalller :: Model :: DBIC'; '+ Html_prefix' = & gt; (Default => 1); Is' + fields_trats = = & gt; (Default = & gt; sub [[MyApp :: Form :: Trait :: Field ']}); '+ Field_name_space' = & gt; (Default = & gt; 'MyApp :: Form :: Field'); '+ Widget_name_space' = & gt; (Default = & gt; sub [[MyApp :: Form :: Widget ']}); '+ Widget_wrapper' = & gt; (Default = & gt; 'none');    
 
  HTML :: FormHandler :: DBIC  In order to help in this situation, in a mousal characteristic, you can inherit from your base class, and in your form using the DBIC model, you get the  formhanger :: travelfor :: model :: dbic With '

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....
