GNU ls columns

[mahkoh]

You've been asking about how to calculate the columns.

First you'll have to calculate the the widths of strings which isn't easy when you have unicode file names: here

Then you'll have to get the width of the terminal: here (tested only on linux)

Then you'll have to calculate the actual widths of the columns the way GNU ls does it: here (this is very similar to the way GNU ls does it)

This code is from my own ls implementation which I'm too lazy to continue. If you want you can use it under the MIT license.

Yay, thanks for this. I relicenced exa to MIT because that seemed to be the main one round these here parts, so there's now no issue of code sharing.

I'm going to take a look at your code and probably steal some of it because I can't bend my mind about the way that ls calculates the rows and columns.

Started working on this today in the grid-view branch.
