regex - Match first word at the beginning of a line (Vim)

Question

Example:

# Objects:
math =
  root: Math.sqrt
  square: square
  cube: (x) -> x * square x

# Splats:
race = (winner, runnners...) ->
  print winner, runners

I want to match cube and race (variables/objects that store functions).

I realized I can't use ^w because it won't match the words with a space behind, like cube.

What regex should I use in this case?

Answer 1

with your current example, this pattern would find those text:

/zsS+zes*[:=]s*(

it matches text, which followed by any number of spaces and a : or = then any number of spaces, then a (. I hope this is what you are looking for.

I used S+ instead of w because I don't kown if char like -, # etc. also could be used as variable name.
