strip doesn't take a character set?

[Xeno Campanoli]

I wanna do something like newstr = str.strip(/\D/)

I know I could do newstr = str.sub(/^\D*/,'').sub(/\D*$/,''), but is there any
better way?

I wanna do something like newstr = str.strip(/\D/)

I know I could do newstr = str.sub(/^\D*/,'').sub(/\D*$/,''), but is there any
better way?

Maybe

newstr = str.sub /\A\D*(.*?)\D*\z/, '\\1'
newstr = str[/\A\D*(.*?)\D*\z/, 1]

Kind regards

I wanna do something like newstr =3D str.strip(/\D/)

I know I could do newstr =3D str.sub(/^\D*/,'').sub(/\D*$/,''), but is th= ere any
better way?

Maybe

str.sub(/^\D*(.*)\D*$/, '\1')

Use #slice / #[]:

irb(main):006:0> s = "aaa111bbb222ccc"
=> "aaa111bbb222ccc"
irb(main):007:0> s[/\A\D*(.*)\D*\z/, 1]
=> "111bbb222ccc"

=> "111bbb222ccc"

Oops, gotta be non-greedy:

irb(main):001:0> s = "aaa111bbb222ccc"
=> "aaa111bbb222ccc"
irb(main):002:0> s[/\A\D*(.*?)\D*\z/, 1]
=> "111bbb222"

Maybe

newstr = str.sub /\A\D*(.*?)\D*\z/, '\\1'
newstr = str[/\A\D*(.*?)\D*\z/, 1]

And a final tweak to account for \n:
newstr = str.sub /\A\D*(.*?)\D*\z/m, '\\1'
newstr = str[/\A\D*(.*?)\D*\z/m, 1]
