perl-Text-Aligner

Module to align text

Text::Aligner exports a single function, align(), which is used to justify strings to various alignment styles. The alignment specification is the first argument, followed by any number of scalars which are subject to alignment. The operation depends on context. In list context, a list of the justified scalars is returned. In scalar context, the justified arguments are joined into a single string with newlines appended. The original arguments remain unchanged. In void context, in-place justification is attempted. In this case, all arguments must be lvalues. Align() also does one level of scalar dereferencing. That is, whenever one of the arguments is a scalar reference, the scalar pointed to is aligned instead. Other references are simply stringified. An undefined argument is interpreted as an empty string without complaint. Alignment respects colorizing escape sequences a la Term::ANSIColor which means it knows that these sequences don't take up space on the screen.
