I'm new to VimScript and trying to learn how to construct patterns.

Is there a Vim plugin like RegExr.com for testing patterns?

There is a very simple way, for which you do not need any plugin. Open a file with some content, turn on :set incsearch and/or :set hlsearch and try it out interactively with Vim.

That's how you learn best, using the tools that you have available.


The trace provide you a preview of the substitution and privide a good help to learn regular expression patterns.
