如何在ruby中使用gsub regex

Question

I want to remove some part of string from using ruby regex:

value = localhost:8393/foobar/1 test:foobartest I want to remove "test" from my string [localhost:8393/foobar/1 test:foobartest] and rest of the value so that output should look like:

localhost:8393/foobar/1

How to do this in ruby? Can you share some sample code to achieve this?

Appreciated your help in advance! Thanks!

Answer 1

I would do something like this:

value = 'localhost:8393/foobar/1 test:foobartest'

value.split.first
#=> "localhost:8393/foobar/1"

Or if you want to use an regexp:

value.sub(/ test.*/, '')
"localhost:8393/foobar/1"
