Does word under cursor match pattern?

Does word under cursor match pattern?

[Paulo J. Matos]

Hi,

I am trying to know if a word under the cursor matched a pattern
([Bb]-?[0-9]+). My idea was:
- Select region with word under cursor
- Transform region into string
- Apply regexp on string

This has one problem: I can't seem to find a function to transform a
region into a string. On the other hand maybe I can work with the region
directly.

Any tips on how to do this?

Cheers,

This is a job for looking-at.

You can use e.g. (thing-at-point 'word). This would return the string
with properties and such, if you want that.
