Is it possible with Bukkit to add a function to detect if a player looks a monster or another player?

Use pcursor() with entities_in_radius() for long-range targets, player_interact_entity event for close targets (player triggered), or, if you really want, iterate through the line-of-sight vector so you can look straight at a mob instead of the block they're on. CommandHelper could do these things for you, but you can do them for yourself. There's no shortcut in Bukkit last I checked.

entity_line_of_sight() and entity_can_see() were added in build #2404.

having a built in line of sight function would be handy, as i gave it a go a while ago and was having some trouble with the maths involved. Didn't stick at it for long though.
something like entities_in_view(loc,yaw,pitch,radius,maxdistance,nonobscured)
probably better to split that into a few different functions though.
Understandably low priority though, as i know it's possible to do this myself.

Thank you for your answers
But the method with pcursor() and entities_in_radius() is not enough precise for me and I need a range longer than it is possible with player_interact_entity, I will try to do this myself with the line-of-sight vector.
I had seen that there was a getLineOfSight function in Bukkit
