How to run a ruby command?

[lixiangnlp]

Hi, I am a new one for Ruby. I have installed the pragmatic_segmenter with the command "sudo gem install pragmatic_segmenter". And could you give my a example rb file to run the tool for text? Because I met the following error when I use the command as your usage in the irb environment.

NameError: uninitialized constant PragmaticSegmenter
from (irb):2
from /usr/bin/irb:12:in `

'

Hi @lixiangnlp

After you open IRB, you first need to type the following command:
require 'pragmatic_segmenter'

Also, if you have an rb file that you want to run, you would need to include require 'pragmatic_segmenter' at the top of the file.

If you still have trouble getting it to work please let me know.
