Re: Long array -> multiple columns?

in reply to Long array -> multiple columns?

There is a common Un*x tool called column that can do this job, and if you're familiar with the Un*x directory listing command ls, then you're probably familiar with the multiple-column output that it produces.

I just looked at the C source code to this utility, and it's an ugly mess. Small and efficient, possibly, but not particularly literate. It looks like someone thought that a robo-indenting tool made code readable, because everything is indented consistently but there's nary a comment to explain how it works.

This is something I thought I had seen on CPAN, but I guess Text::Table is a bit different in purpose.

One advantage of ls's method (and presumably column's) is that it resizes the columns to fit what will be placed in them and takes into account the width of the terminal.
