VSCodeVim delete all occurrences containing a pattern

Question

I would like to delete some prefix from all words in document using VSCodeVim plugin. For example:

var someVarOne, someVarTwo, someVarThree;

delete prefix 'some' and get:

var VarOne, VarTwo, VarThree;

Thanks in advance!

Answer 1

Try:

%s/some\(Var\w*\)/\1/g

• \(...\) defines a group
• \w* one or more word chars
• \1 replaced with the first group (whatever matched by Var\w*)

Answer 2

Assuming your var are camelCase as you showed and that only the "some" word is known (i.e., "Var" might change) try this regex:

some(([A-Z][a-z]*)+)

and replace with \1

regex demo.

Works on

var someVarOne, someVarTwo, someVarThree, someOtherVar, someVar, someThing;

var some;

producing:

var VarOne, VarTwo, VarThree, OtherVar, Var, Thing;

var some;

Answer 3

Since the substitution methods have already been mentioned, you could try this simple method:

1. Visually select the word to be replaced (here it's "some") using the v key.
2. Place multiple cursors at all places where the word "some" has occurred by Ctrl+Shift+L or Cmd+Shift+L keys.
3. Delete the visually selected parts using d key which stands for delete
