How do I use (n)curses in Ruby?

Question

I\'d like to create a progress bar to indicate the status of an a batch job in Ruby.

I\'ve read some tutorials / libraries on using (n)curses,

Answer 1

You might be able to get some implementation ideas from the Ruby/ProgressBar library, which generates text progress bars. I stumbled across it a couple of months back but haven't made any use of it.

Answer 2

On windows, curses works out of the box, ncurses doesn't, and for a progress bar curses should be sufficient. So, use curses instead of ncurses.

Also, both curses and ncurses are wafer-thin wrappers around the c library - that means you don't really need Ruby-specific tutorials.

However, on the site for the PickAxe you can download all the code examples for the book. The file "ex1423.rb" contains a curses demo which plays Pong - that should give you plenty of material to get you going.

Answer 3

Very late answer and sorry for self promotion, but I created library to show progress in terminal.

Answer 4

Personally I think curses is overkill in this case. While the curses lib is nice (and I frequently use it myself) it's a PITA to relearn every time I haven't needed it for 12 months which has to be the sign of a bad interface design.

If for some reason you can't get on with the progress bar lib Joey suggested roll your own and release it under a pretty free licence for instant kudos :)
