simple code

hi

#!/usr/bin/ruby -w
re=Regexp.new('\s+[A-Z]')
puts " {| class=\"wikitable\"
|-
Table -- put your title here
|-"
while line = gets
md=re.match(line)
if md =~ nil
else
puts md
end
end

I input the text as


COM - Commercial
EDU - Educational
GOV - Povernment
NET - Network
MIL - Military
ORG - Non-profit organisations



and I get the result as

{| class="wikitable"
|-
Table -- put your title here
|-
nil
C
E
G
N
M
O
nil


How do I prevent the nil appearing?
How do I access each matchdata with the postmatchdata on each line?

while line = gets
md=re.match(line)
if md =~ nil

Try "if md.nil?" instead.

else
puts md

puts md, md.post_match

 

[7stud --]

Try "if md.nil?" instead.

if md
#do stuff

puts md, md.post_match

puts line




Try this:

re=Regexp.new('^\s+[A-Z]') #match start of line only
...
...
while line = gets
md=re.match(line)

if md
puts line
end

end

re = /\s+[A-Z]/

puts ' {| class="wikitable"

while line = gets
puts line if line =~ re
