I wrote a tool to perform X. It was rejected by a journal as not novel. I wrote to the editor saying there is currently no tool to do X. They acknowledged this.
When the issue I was rejected from came out, it contained another tool which did X. I have not tried to republish my paper, but it is on the internet and has been posted to forums.
A) Should the editor have mentioned in my rejection that they were just about to publish a similar paper? This may have changed what I did (ie publish elsewhere)
The other paper said "there is currently no tool to do X". The author almost certainly didn't know about my tool/site.
B) Should the editor have suggested the paper cite my tool/website? Or at least not allowed the authors to say "there is no tool to do X"?
C) What should I do? Just give up on my paper?
