vim set ex range to current paragraph without visual/mark etc

Question

I'm wanting to apply a command to the currect paragraph but I'd like to automate it so I don't need to visually select/mark the paragraph before-hand.

I want something like

:{,}s/this isn't/important/g  

to specify the range to apply 's' (in this case) to.

Eventually I'm wanting to using range-accepting-commands to reformat a paragraph.

Does anyone know how to do this? Is there a better approach that I'm missing?

Answer 1

:'{,'}s/this isn't/important/g

See:

:h '{
