I need to make this clear - "betty frustrates me!".
Over the time though, I've learnt to avoid her and I'll tell you how, but first...
Betty is actually a very real person 🤯, according to Wikipedia...
Frances Elizabeth Holberton was an American computer scientist who was one of the six original programmers of the first general-purpose electronic digital computer, ENIAC. The other five ENIAC programmers were Jean Bartik, Ruth Teitelbaum, Kathleen Antonelli, Marlyn Meltzer, and Frances Spence.
But seriously, this isn't the Betty we'll be talking about today.
Betty is a Holberton-style C code checker written in perl.
Now there's some explanation needed for the above sentence, so I'll start with...
Holberton is a computer science school founded in silicon valley (that's all you get 😴)
Also known as linter.
Lint, or a linter, is a static code analysis tool used to flag programming errors, bugs, stylistic errors and suspicious constructs.
This means that Betty does not have to run or compile your C code before she detects potential errors and wrong styles.
It's just another programming language like C.
Hold on! So Betty is basically a program in one language trying to detect errors in another language 🤦🏾♂️
Now that you know Betty, how do you use Betty?
I'm assuming you already have Betty installed. If you don't, checkout the installation guide here
The usage is basically just
FILE... means 1 file or more.
Once you run Betty like this, Betty would enter each file you specified and do a series of checks. Here is a list of the things Betty checks for
Length of each line
Placement of braces
Placement of spaces
Naming of variables, functions, structs...
Length of functions 🤨
Macros & Enums
You can find exhaustive information on Holberton-style code here, so you don't fall a victim of Betty as I did 😂😭
