txbut - I should'a made clear I have no mandate to install a whole new library.
Does it contain a snippet like this?
def row_to_pipes(row, widths)
widths = widths.dup
return ' ' + row.map{|c|
case c
when Fixnum
c.to_s.rjust(widths.shift)
else
c.to_s.ljust(widths.shift)
end
}.join(' | ') + ' '
end
def table_to_pipes(table)
widths = (0 ... table.first.length).map do |x|
table.sort_by{|q| q[x].to_s.length }.last[x].to_s.length
end
table.map{|r| row_to_pipes(r, widths) }.join("\n")
end
test 'array to pipes' do
assert_equal ' a | b | c ', row_to_pipes(%w(a b c), [1, 2, 1])
end
test 'table to pipes' do
assert_equal " a | bb | c \n d | 2 | f ",
table_to_pipes([%w(a bb c), ['d', 2, 'f']])
end
Understand I would never write code this sloppy in production. Really! I'm just
letting it out here so if anyone can think of a way to refactor it and DRY it
up, we could make a little good-code experiment out of it.
It provides the effect I'm after:
puts table_to_pipes( [['__concept__', '__frobs', '__zones'],
[ 'Unruly Pygmy', 6, 10001 ],
[ 'Renonymize', 4, 9999 ],
[ 'Opramatic', 4, 10001 ],
[ 'El Pollo Psycho', 4, 10002 ],
[ 'Mouse Guard', 4, 10003 ],
[ 'layuhponit', 4, 10004 ]] )
__concept__ | __frobs | __zones
Unruly Pygmy | 6 | 10001
Renonymize | 4 | 9999
Opramatic | 4 | 10001
El Pollo Psycho | 4 | 10002
Mouse Guard | 4 | 10003
layuhponit | 4 | 10004
