I saw lot's of different posts/answers to put the proof at the end, but none of them fully convince me. Indeed, I'd like to have the following:

  1. a way to put the proofs in different sections: some proofs may stay on place, some proofs may go to appendix in section A, some may to to appendix in section B... Ideally, creating a new "kind" of proof to put it somewhere else should be easy.
  2. with a way to link automatically the proof and the theorem: at the end of the theorem, I'd like a sentence like See \autoref{proof:myproof} page XX, and at the end of the proof I'd like a sentece like See \autoref{thm:mytheorem} page XX (with links enabled of course), and moving a proof from one "kind" to another should be easy as well.
  3. I want to be able to treat lemma and theorems together, I don't want to treat them as two different objects and push them at two different places
  4. I want to be able to give them a name, and use \autoref{lem:mylemma} to refer to them (with link of course) across the document
  5. they should behave "nicely" with counters from reals theorems/proofs. Indeed, some people in the team may still use the commands given by \newtheorem defined with amsthm/thmtools, and I don't want to disturb them, and therefore a "custom" theorem-proof-at-the-end after a "real" theorem should have a number next to the one of the theorem. Usually, I like my lemma and theorem to share the same counter that derives from the section one.
  6. I use a lot the synctex functions that let me go from a point to the PDF to the corresponding line in my .tex, and reversely, that goes from a line in my .tex to the corresponding line in my .pdf, so I would love to be able to use synctex on the proofs as well. If it's not possible when the proof is at the end, at least I'd like to be able to use synctex when I'm writting the proof, i.e. when it is not yet pushed in the appendix. But a synctex that works all the time would be awesome!
  7. Eventually, an option to be able to restate the theorem in the appendix before the proof would be interesting.

Let me know if you have a nice solution! I'm trying to adapt a method based on tcbox, but it's a bit hard to make synctex work with it. Also, if you propose a solution, could you please indicate if some items are not respected?

Thanks a lot!

MWE: I started with this code. It works pretty well, but as it it's not trivial to create new "proof kind" easily. I started from How to place all proofs automatically in appendix?

Update: I decided to create a real library out of this project. I'm now uploading it on CTAN, but meanwhile you can find the whole project here https://github.com/leo-colisson/proofAtTheEnd/

The syntax is now an environment, which is clearer I think. To use it in your project, first download it:

cd <your project>
repopratend="https://raw.githubusercontent.com/leo-colisson/proofAtTheEnd"
wget ${repopratend}/master/proofAtTheEnd.sty
wget ${repopratend}/master/xparse.sty

load it in your project:

\usepackage{proofAtTheEnd}

and use it with:

\begin{theoremEnd}{thm}[Yes I can have a title]
  \label{thm:ilikelabels}
  Creating a new theorem is easy
\end{theoremEnd}
\begin{proofEnd}
  You want a proof? Here is it!
\end{proofEnd}

And put where you want to write the proofs the code

\printProofs

You can do much more with it, see the documentation here : https://github.com/leo-colisson/proofAtTheEnd/ !


First version:

After spending quite a long time to find a nice solution, I came up to do my own "mini-library". The code is not really a one line solution, but it's really customizable, easy to change, it does not involve complex latex code, but it works greatly! I manage to solve all the tasks above, even more (I added the possibility to add text in the appendix appart from theorem, restate theorem before the main theorem...), and it's super easy to use! The only "problem" is that when you click on a proof in appendix, you are redirected to an input file that is created by the script instead of staying in the main file... But you can with one word write the proof both in appendix and in the main paper (where synctex works), which is practical when you write the proof ;-) If you would like to have something that is not present here, let me know!

But pictures are better than words: enter image description here

And the code to produce a theorem looks like (change thm into the name of the environment you want to use, like lemma...):

\theoremProofEnd{thm}[Yes I can have a title]{\label{thm:ilikelabels}
  If $1+1=2$, then $2 = 1+1$.
}{
  Come on, you can do it!
}

and to print the proofs, you just write wherever you want

\printProofs

Now, you can also add styles to the theorem to have more power. For example, if you want to restate the theorem in the appendix, and put it in another section of the appendix (you will create another "category" or theorems), you just need to write

\theoremProofEnd[restate, category=myimportanttheorems]{thm}[Quantum Yao's XOR Lemma]{
  The Yao's XOR Lemma for one-rounds protocols with quantum adversary holds.
}{
  If you have the proof, let me know!
}

And to load the "important theorems" in another section:

\section{Proofs that are important}
\printProofs[myimportanttheorems]

You can easily change the defaults, or even define you own style using something like:

\pgfkeys{/prAtEnd/custom defaults/.style={
     category=greattheorem
   }
 }

You can also add comments only in appendix (or use option both if you want the comment in both the appendix and the main text) with

\textInAppendix{See, I am a simple text in appendix only.}

Finally, you can also restate a theorem before, by using:

\section{Section with restate before theorem}
\theoremProofEndRestateBefore{thm}[Title]{laterrestatable}{
  This theorem has been introduced before the real definition.
}

\section{Section with late theorems}
\theoremProofEnd[restated before]{thm}{laterrestatable}{
  To state a theorem before the initial definition, use theoremProofEndRestateBefore where you first want to state the theorem, with a unique name in the second mandatory argument, and when you want to insert the theorem for the second time, use the usual theoremProofEnd command with the same unique name as before in place of the theorem definition.
}

The list of options for theorems are (you can add no in front of most options to negate them):

  • category=mystupidtheorems to change the group of the theorem (each group can be included in a different place)
  • proof here: if you want the proof to be written in the main text
  • proof end: if you want the proof in the appendix
  • restate: if you want to restate the theorem in the appendix
  • link to proof: to add a link after the theorem to the proof
  • both: (only with \textInAppendix) to put a text also in the main body
  • default: options by defaults
  • custom defaults: to overwrite the defaults
  • normal: theorem without proof in the appendix
  • debug: alias for proof here, useful to have a copy of the proof in the main paper to use synctex to navigate between paper and proof easily.
  • stared: Just displays 'Proof' in the appendix, with a link to the theorem
  • no link to theorem: Just displays 'Proof' in the appendix, with no link to the theorem
  • text link: Text used in the link to the proof, defaults to See \hyperref[proof:prAtEnd\thecounterAllProofEnd]{proof} on page~\pageref{proof:prAtEnd\thecounterAllProofEnd}
  • text proof: Text used in the title of the proof, defaults to {Proof of \string\autoref{thm:prAtEnd\thecounterAllProofEnd}}

Enjoy!
