Reading and Writing to Tempfile

ruby-talk

Hello,

I'm having a hard time getting tempfile to work correctly for me. I
have a couple of questions

Isn't it possible to open a tempfile, write to it, close it then later
open it again write to it and close it?
I don't seem to be able to do that. Every time I write to the file it
only or over writes what is in the file.

require 'tempfile'

temp = Tempfile.new("stuff")
name = temp.path
temp.puts "I was here"
temp.close

# here I'd like to reopen the file and write another line

#later
temp.open
str = temp.gets # I was here

temp.close(true)

What am I doing wrong?

Any help is good, thank you.

Check the documentation on IO (I know, I know...the class is "File" but all the important documentation is under "IO"). Specifically, you want to set the mode on the file to "a" instead of just "w" when you open it.
