VIsual select to a specific character

I am working in vim. I have a piece text that looks like :

one = 24
two = 52
three = 56
four = 74

Is there a way to use visual select to yank and paste up to the equal to sign in each line ? I want an operation that leaves me with the following result :

one = 24
two = 52
three = 56
four = 74

one = 
two = 
three =
four =

My current solution is to copy the whole thing, then jump to the one = 24 line in what I copied and then record this macro : 0f=ld$j to @w and then repeat it three times with 3@w. Is there a way to do this using visual select and yank and paste ?

From anywhere on each line:

0vf=
  • '0' starts your selection at the beginning of the line, so it's unneeded (but harmless) if the cursor's there already
  • 'v' enters Visual mode
  • 'f=' selects up to and including the first '=' on the line.

You could use a mapping like this

vnoremap ,s y:let @"=system('sed -nE "s/=.*/=/p"',@")<cr>

When selecting now some lines in in visual mode, type ,s. This will put the desired modification into the " register and you can paste them now using p wherever you want.

How about 

:global /=/ copy $ | substitute /=\zs.*//

We use global to select the original lines, then copy them to the end $ and remove the parts after = with substitute.

I tend to use :substitute for these things

" First I yank and paste, in normal mode
yapP

" Then I transform
gv   " to reselect, while in normal mode
:s/=.*/=/   " that will actual display :'<,'>s/.....

The actual reselection part may need a little work depending on where the cleared snippet shall appear. May be something like yapo<esc>p:'[,']s/=.*/=/ + enter

You can visually select the lines to apply normal commands to them with :norm.

Thus, you could do:

ggVG:norm f=ld$
