I've got this simple task but I'm trying to perfect it as best I
can to learn something in the process.
I have Linux terminal ASCII codes for coloring terminal output.
string red(string) { /* ... */ }
"Hello world".red => "\033[31mHello World\033[0m"
which translates to "[red]Hello World[reset to normal text]".
I have to do some slight trickery so I can chain them. But it all
works fine. __The function is the same__ no matter what kind of
color, bold, etc attribute I want. The only difference is the
tag/prefix string.
So I have a table (or enum):
enum colors{
reset = "\033[0m",
red = "\033[31m",
bold = "\033[1m" //...
}
Absolute perfection would be some way to add a single line to
that enum (or table) and magically get a new function. I add
"blue" with its prefix code to the enum and immediately I can do:
"hello world".blue
Add yellow = "\033..." and I can do:
"hello world".bold.yellow
It's an interesting problem. Right now, I made a generic version
that accepts the prefix code string directly called "color()" and
red() translates to a call to color with the red string. blue()
does the same. And so on. But it's still plenty of boiler plate.
I do that so I don't have 80+ functions all a half-page
long--which would be a nightmare to verify.
It's surely nothing mission critical. But I wonder if I can
distill this simple problem down further, I may be able to learn
some tricks for later problems.
Thanks.
