c - Can you capitalize a pasted token in a macro? -


In C macros, is it possible to capitalize a paste-in token? For example, I currently have the following macros: 

  #define test (name, keyword) \ test_ ## name: test _ ## keyword ## _keyword

I will do this as follows: 

  exam (test1, test1)

which will be as follows: 

  test_test1: TEST_TEST1_KEYWORD

Now, instead of typing the same name twice (with all lower case letters once and then with all upper case letters), there is no way That I do any of the following Is power, and either change the token in all uppercase letters or all lowercase letters? 

  test (test1) or test (test1)

thanks, Ryan

As far as I know, it can be done on tokens only to make 'Sterefove' or copy in the only operation C preprocessor (at least ISO / ANSI standard). I am also unaware of any GCC or MSVC extension that will let you do what you want to do.

However, people are coming up with magical (or awful) things in clever (or strange) macros, so I will not be surprised if I wonder.

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....
