I want to enumerate Dave-Letterman Style with the last listed first as in enumerating top ten items and having them listed in 10 9 8 7 6 5 4 3 2 1. Is the etaremune package the only way to go?

Edit: I realized my question is vague and incomplete.

Does any package have the ability to change the order of appearance of a collection of entries. Consider a long already-typed list. I may want one of two things,

  1. Changing the order of appearance of items. Say it is typed as 1) Apples, 2)Oranges 3)Pears and I want it to appear as 1)Pears, 2)Apples, 3)oranges. Of course I could cut/paste the original text, but what if the table is long/etc ...

  2. Changing the way enumeration shows up as in 1,2,3 vs 3,2,1.

Also, what if a table of items breaks across a page. If all items are on one page then switching the enumeration from 1,2,3 to 3,2,1 would be easy. But if the list breaks across a page then many times it is better to count in reverse. And the question is how do you do this automatically.

    Any specific reason not to use etaremune? – Joseph Wright Aug 25 '13 at 15:59

    Another alternative would be revnum, but in neither case do we have a reason not to use the package. – wasteofspace Aug 25 '13 at 16:02
  • @JosephWright I thought there would be an option to enumerate. But, to the main point, eventually I want a list of items that gets split across a page to be automatically done in reverse, and otherwise to be numbered in the usual way. – Maesumi Aug 25 '13 at 16:33

    If you don't want to use etaremune, try http://tex.stackexchange.com/a/110263/34355 – Dan Aug 26 '13 at 18:32
  • It seems to me that you're asking two very different questions here: 1) change the order of the items in a list (not the numbering, but the actual text of the items), and 2) detecting if a page break occurs within a numbered list, and in that case use etaremune or similar instead of enumerate. Do you want one new environment that can do both things? If not, I think I would edit this question to be about just one of the issues, and create a new question about the other. – Torbjørn T.

  • I'm duping here as otherwise the problem is unclear anyway! – Joseph Wright Sep 08 '13 at 16:06
  • @TorbjørnT. Yes, I think I'd better rewrite this question. It became tangled. I guess reordering a text is somewhat similar to using bibtex, but inside the main body of a document. And changing from enumerate to etaremune at page breaks is totally a separate issue. – Maesumi Sep 09 '13 at 16:22
