You can do this yourself, providing you have enough rep. Which if this is you then you do.

Retag all the questions from ast to abstract-syntax-tree Then propose a new synonym to convert all further questions tagged ast are automatically converted to abstract-syntax-tree.


AS Roger has pointed out, a Diamond Moderator will be able to merge these tags for you as there are a fair few questions to be re-tagged.

  • There are 50 [ast] and 46 [abstract-syntax-tree]. Manual merges are discouraged for that many. Diamond moderators can rename these tags with a single click and no noise on the homepage. However, we can use synonyms for that now, and they can merge after it's voted in.

  • @Roger - Didn't realise they are discouraged. Each time I have asked it has been a case of DIY. Commented Oct 23, 2010 at 10:45
  • @Barry: For low numbers, but I can't recall anyone saying about 50 is close to low enough in normal circumstances.

  • @Roger - Fair enough. I seem to remember re-tagging about 25-30 or so a while back. Now I'm pretty sure I wasted my time :-) Cheers Commented Oct 23, 2010 at 10:49
  • @Barry: Thanks for that effort anyway! If you have 2k, you can vote for the synonym, which seems to be how things will play out more often from here on out.

  • Gah, you include the update and I remove my downvote to have someone add another... but anyway, see meta.stackexchange.com/questions/38987/…

    All: I've manually retagged probably a dozen tags since joining SO. Early in SO's life, there were often only a handful and doing it manually seemed... OK. 20 is about the point where I lose patience; there's 50+ "ast" tags. Glad to hear somebody might do it en masse, which is the reason for the polite "retag-request".
