Much the same story exists for another common use of aligning, aligning the values of a hash: Again, the aligned version looks nicer, but a simple change like adding a value for a new key “Spaces,” reads one argument. a merge conflict that needs to be manually resolved, costing developer time and energy, and creating Having only one way is better than having two ways. Tabs v/s Spaces.

But how much less can it be, 15%, 12%, 10%? Spaces are essential because we need them for other things like separating words in source code. Why were ‘Tabs’ created when we already had spaces? Suppose average indent in a program is 3 levels and average code length (without indents) in a line is 50 chars and total lines is 100, then the file size we have with space indentation is 100 * (50 + 3*4) = 6200. For indentation right, what other... 2.

I learned EMACS in 1983 and freely intermixed tabs and spaces until LAST YEAR, when a young programmer explained to me the errors of my ways. Yes, I have seen code examples like this in the wild. Again, this is a very rare situation but because tabs = spaces has been established after point 2, this adds weight to the tabs category. So these are my pro-Tabs reasons. Gotcha. cancelHandler. Saving 17% of space is just not worth the effort in what we produce mostly these days, Perhaps worth mentioning is compression libraries - something you should apply when you really want to optimize that 17%. let me illustrate with a quick story, why i irrevocably turned from a spaces to tabs guy.

This means that each one will be comfortable with the code that uses his/her indentation width and will find annoying the other style. It may be an obscure argument among programmers about how to format code – but it's also an age-old battle that still burns hot in development circles ("Tabs versus Spaces: An Eternal Holy War" was published in 2000). If the code has been indented by spaces and you are trying to add a few lines in the code, you will have to use 4 times spaces for each level of indentation. Here's why. Here is the code I … It’s deeply personal, and we’re all In fact, they did better in the 19th century! Read programming tutorials, share your knowledge, and become better developers together. As I already told at the start of this article, tab width … Tabs and spaces are both fine for indentation. Give Avi Aryan a like if it's helpful. That’s all for now. It is considered a single character that is just wider than others. Some may prefer tab size 2.
