making a class in irb

[Sidney Reilley]

Ruby noob here! Using irb to learn.
created a sample class with 2 instance vars.
tried to access the vars. NO JOY!
Forgot to include the attr_reader.
Is there a way to amend/update a class in the irb?
Or do I have to re-type the entire class over again?
TIA ...

Best to use a different environment.

- install the filewatcher gem
- create a test file named app.rb with proper ruby headers at the top
- create an alias in your .bash_profile like this:

kk='filewatcher "/users/sidney/app.rb" "clear; ruby /users/sidney/app.rb"'

in the terminal, type kk, and it will be running. When you edit the file and save it, it will run in the terminal. This is a much better option than irb.

Good stuff! Thx for heads up for this useful solution.
