ysf / anewer Goto Github PK

Hi ! After posting this tweet, @sn0int mentioned anewer tool, which is an awesome, modern replacement for anew.

My feature request is about supporting advisory locks flock(2) on linux. Indeed, when 2 instances of anew/anewer try to write to the same file, both may end up using an outdated hashmap, and then allowing to add duplicate results to the file.

Implementing flock on the opened file would prevent this.

I understand that it may sound overkill, and i don't know if it's easy to implement in rust

@ysf It would be good if it have invert match functionality too which is not in anew.

Of course that can be done with filters before, but it would be easier to be able to specify an option to e.g., ignore changed numbers or timestamp-like data.

I assume simply regexp-changing the string to hash will allow that. It would only need to find nice regular expressions for some common filters.

by default, anew opens file with O_CREAT. despite liking anewer's behavior of failing i file doesn't exist, it would be nice to have a flag -c, --create to be able to ask anewer to create the file if it doesn't exist yet
