Question

Is it possible to provide some parameter when recording a macro in vim via prompt or some other ways?

Edit:
I have such code:

foo
bar

And I would like to surround each with ruby block:

expect do
  foo
end.to raise_error(CustomClass)

expect do
  foo
end.to raise_error(OtherCustomClass)

So, it is easy to create a macro that will result with:
expect do
foo
end.to raise_error()

expect do
  foo
end.to raise_error()

But it will be nice to have prompt that will be used to set raise_error method parameter. In each use of macro this parameter will be different.

While I agree with everyone else that if you need this feature, you’re probably going about things inefficiently, it is possible to insert a variable text string into a document as part of a macro. The trick is to store the text you want to use in your macro in a register.

1. yank some text into a named register, for example "xyw to yank a word into the x register
2. record your macro, qq, when you want to place the variable text, put it, for example "xp to put the text in the x register into the document where the cursor is
3. now, when you play your q macro, @q, it will use whatever is currently in the x register, so you can yank different text into the x register, play your q macro, and the newly yanked text will be used.
