Hy list,


I would like to append to a ruby script a tarball and a license file.

Both are in the form:

# data........................................
# data........................................
# data........................................

How would you convert the tarball binary data?


The licence text should be centred in a 55 char space.




If I split the license text lines and then gsub(/\n/, '\n') them=20
i have a bad output:

[55 char]
# use pieces of it
# in new free programs; and that you know you can do


=2D----------------
x =3D 0
y =3D 54
lines =3D []

loop {
i =3D f[x..y]
break if i.nil?()
lines.push(("# " + i))
x +=3D 54
y +=3D 54
}

lines.each{|i| puts i }
=2D--------------


Tnx.

tar = "i6\253m\251e" # in: binary content
b64 = [tar].pack('m') # out: Base64 encoded string
p b64 #-> "aTarball\n"

If you split on /\n/, the newline will disappear so it's
not now available to gsub.


What about this ?

# make some input data
licin = <<EOL
LIC ............A
LIC ............B
LIC ............C
EOL

licout = licin.map {|line| '# ' << line}
puts licout

# LIC ............A
# LIC ............B
# LIC ............C

excellent!

I dont split on "\n".

I need to center the license text in a TextEdit Window, this widget
is 55 char large.
I split the file in lines of 55 char:

x =3D 0
y =3D 54
lines =3D []

loop {
i =3D f[x..y]
break if i.nil?()
lines.push(("# " + i))
x +=3D 55
y +=3D 55
}

lines.each{|i| puts i }


The problem 1 (tab related) is in centred input:
in:
[ tab space ] Gnu Gpl [ tab space ]| <- 70 char
|
out:
[ tab space ] Gnu Gpl [ tab ]| <- 55 char

So the output text is right aligned.
How can i center the text in a 55 char space?


The problem 2 (\n related) is in carriage return:
in:
bla bla bla ...................................bl
a
out:
bla bla bla ...
bl
a

Should i delete all "\n" that not follow a '.'?

No.
I think you should reformat gpl.txt in a text editor
so that it's exactly the way you want it to look.
Then display your new file in the widget ??

Otherwise you will be writing a text formatter

I've once written this String#reformat. It might help you. I
added a test to the script.

very, very, good!

*I changed paragraphs.join("\n\n") to paragraphs.join("\n#\n") and

Use the prefix: paragraphs.join("\n#{prefix}\n")
