• Count white spaces to the left of a line in a text file using C++

  - by insertable

  Hi all, I am just trying to count the number of white spaces to the LEFT of a line from a text file. I have been using count( line.begin(), line.end(), ' ' ); but obviously that includes ALL white spaces to the left, in between words and to the right. So basically what I'm wanting it to do is once it hits a non-space character stop it from counting the white spaces. Thanks everyone.

• How do you edit tab labels per tab in GVim?

  - by Neil

  How do you edit a tab label, per tab, in GVim? You can do this: set guitablabel=foo But that will set every tab's label to "foo". The documentation seems to suggest using a t:var, like this: let t:guitablabel="foo" But it doesn't do anything. Is there any way to give each different tab a different name?
