Hi people

Where does Ruby get its initial $LOAD\_PATH?

Where is its startup file? ie. what script loads these:

I believe it’s compiled into the Ruby executable.

$LOADED\_FEATURES gets added to dynamically as you require/load things  
at runtime.

Whatever you typed to get the “\>\>” prompt.

Looking at this huge list of things, I’m not sure what you ran. It’s not  
big  
enough to be rails script/console, but is too big to be plain old irb:

$ irb1.8  
irb(main):001:0\> $LOADED\_FEATURES  
=\> [“irb.rb”, “e2mmap.rb”, “irb/init.rb”, “irb/context.rb”,  
“irb/workspace.rb”, “irb/extend-command.rb”, “irb/ruby-lex.rb”,  
“irb/slex.rb”, “irb/notifier.rb”, “irb/output-method.rb”,  
“irb/ruby-token.rb”, “irb/input-method.rb”, “readline.so”,  
“irb/locale.rb”]  
irb(main):002:0\>

If you try just Ruby by itself, you’ll find nothing is loaded by  
default.

$ ruby1.8 -e ‘p $LOADED\_FEATURES’  
[]

HTH,

Brian.

It WAS irb on my Linux system. I have syntax highlighting and tab  
completion  
turned on though.

default.
