Consecutive numbering and labels in tcolorbox
Those days I write a book, and I use framed boxes tcolorbox
. Have a look:

As you can see, I would like to use these frames only for theorems, propositions, lemmas, corollaries and axioms (and not for the definitions). Also I would like to keep the choice to write some of them (for instance, a theorem) without these frames.
My questions are:
- How can we have consecutive numbering in the whole text?
- Ase you can see, we face a problem with labels in the reference of theorems etc. How can we solve it?

- The tcbtheorem environments allow you to use counters from other tcbtheorems as well as existing LaTeX counters. It will be easier to define the standard LaTeX theorems first (all sharing the same counter), and then define the tcbtheorems (using that same counter).
- The problem is that a label for a tcbtheorem environment needs to be passed as an option to that environment in order for it to work correctly. This is not standard LaTeX behaviour (you would have noticed that labelling and referencing your definition environment would have worked without a hitch).

FYI There was a rogue makeatletter

Works perfect, thank you. But, why makeatletter is a rogue?

It wasn't doing anything. In general makeatletter should only be used 'temporarily', being following shortly by makeatother.

The key is the tcolorbox options use counter=<another counter>
and use counter from= <counter from another tcolorbox>

Thank you very much for your comment. It works nice, but I have one more question. How do we refer to a non framed definition or proposition etc? Normally with "label{}"?

@Chris Do you mean a definition created by anewtheorem
or by anewtcbtheorem
?
– Hafid Boukhoulda

From newtheorem :)

@Chrislabel{mylabel}
thenref{mylabel}
where mylabel can be replaced with something like def:commutative ring

Let $R$ a commutative ring with $1_R$ ...
end{defin}
% tcbtheorem labelling

Let $R$ a commutative ring with $1_R$ ...
end{myprop}
From the Proposition ref{prop:maximal} and definition ref{first_def}ldots
end{document}
Output:
As an aside, I would recommend using the cleveref
package which can easily be set-up with the each tcbtheorem so as to produce a named reference instead of just a number e.g. 'proposition 1.1.2' vs '1.1.2'. That way you don't have to worry about whether you're referencing a theorem, or a definition, or a proposition etc. each time.
FYI There was a rogue makeatletter
in your code.

Works perfect, thank you. But, why makeatletter is a rogue?

It wasn't doing anything. In general makeatletter should only be used 'temporarily', being following shortly by makeatother.
