Suppose that you have a bunch of theorems, propositions, definitions and lemmas, like

Definition 1. A group is said to be …
Lemma 2. Let … Then …
Proof 2. […]
Theorem 3. If … then …
Proof 3. […]

What I would like to do is to have a command like \allResults (or several like \allTheorems, \allDefs, \allLemmas) that returns at the end of the document the statements (without proofs) of the definitions, theorems, lemmas (in the correct order), like this:

Definition 1. A group is said to be …
Lemma 2. Let … Then …
Theorem 3. If … then …

What I tried is to follow the answers to this question. I didn't understand egreg's first code. I liked Andrew's code very much, but I wasn't able to change it for my situation.

Therefore I tried egreg's second code, by creating \allprops and \alltheoremes, but I got errors (see below), as if I created twice something... When I only create \allprops (without \alltheoremes), it works well.

I get errors like 

LaTeX error: "kernel/command-already-defined"
!
! Control sequence \vedran_restatable:n already defined.

My question is: how is it possible to create commands like \allResults (or several like \allTheorems, \allDefs, \allLemmas), either by changing my code, or by using a new and better idea (e.g. egreg's or Andrew's answers here)?

Thank you very much!

    You have copied the definitions of \vedran_restatable more than once

  • @ChristianHupfer : thank you for your comment! Does it mean that I can't use some kind of "restatable" to solve my problem (since I have several environments Theorem, Definition, Proposition, Lemma, to deal with)?

  • Basically, as is setup by egreg you need a ....restatable macro for each theorem type. This can be done in loop, most likely, but requires more work to do. (I am short of time, right now)

The reason is that (as it is defined right now) there must be an individual \vedran_...restatable macro for each of the theorem-like environment.

I am short of time right now, but I'll try to provide a more sophisticated approach for more than just two environments.

  • Thank you very much! It will be very useful, I think. However, we get here first all the theorems, and then all the propositions. Do you know if it is possible to create some kind of \allResults which gives the theorems and propositions in the same order as in the original section?
