amsmath: How can I use the equation numbering and label manually and anywhere?
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ margin-bottom:0;

I want to use the accustomed equation numbering and label manually and anywhere; for example in an array.
With the command newcommand{tagx}[1]{refstepcounter{equation}(theequation)label{#1}}
can I create custom tags tagx or tagx[eq:bar] and reference them as usual eqref{eq:bar}.
But in a tag with an own figure newcommandmytag[2]{begingroup
renewcommand{theequation}{#2}% ändern
(theequation)label{#1} % ausschreiben
endgroup
}
still works mytag[eq:bar1]{***}, but not the referencing eqref{eq:bar1}.
What can I do?
documentclass[12pt]{scrreprt}
usepackage{amsmath, amsfonts, amssymb}
newcommand{tagx}[1]{refstepcounter{equation}(theequation)label{#1}}
newcommandmytag[2]{begingroup
renewcommand{theequation}{#2}% ändern
(theequation)label{#1} % ausschreiben
endgroup

chapter{First Chapter}
An equation for counting:
begin{equation}
a+b=clabel{eq:foo1}
end{equation}
The tag of the equation is eqref{eq:foo1}.
section{Putting a tag in the text}
A normal tag in the text tagx[eq:bar0] and an own tag mytag[eq:bar1]{***} is showing correct.
The referencing of the normal tag in the text eqref{eq:bar0} is correct; but the own tag eqref{eq:bar1} is wrong - here should be "(***)".

The tag of the equation is eqref{eq:foo2}.

why are you usingtheequationinmytag? also shouldn't the argument totagxbe mandatory not optional? If you omit the argument then you will executelabel{}which doesn't really work (and will give errors if done more than once)
– David Carlisle
May 19 at 15:41
@DavidCarlisle I thought it would be better to keep the label name optional. Sotagxgives (1.2) e.g. Andtagx[eq:foo]gives (1.2) and setslabel{eq:foo}. I do not think I have to label all tagx'es there ever will be.
– cis
May 19 at 17:20
in that case you would only want to do thelabelin the case the argument was provided, as it is above if you don't supply the option you end up withlabel{}which is an error.
– David Carlisle
May 19 at 17:22
@DavidCarlisle I changed your solution to% tagx[<label, optional>] % normal tag inline newcommand{tagx}[1]{refstepcounter{equation}(theequation)label{#1}}That is wrong?
– cis
May 19 at 17:38
yes that is wrong as you dolabel{}if the argument is not provided.

Your mytag command doesn't set @currentlabel.

I'm not sure why the “label” argument is optional: you need it, don't you?

Ah, I see: you put both commands together.

@ egreg Is it possible, to make the label-name ('eq:bar1' e.g.) an optional argument too?

why are you using
theequationinmytag? also shouldn't the argument totagxbe mandatory not optional? If you omit the argument then you will executelabel{}which doesn't really work (and will give errors if done more than once)– David Carlisle
May 19 at 15:41
@DavidCarlisle I thought it would be better to keep the label name optional. So
tagxgives (1.2) e.g. Andtagx[eq:foo]gives (1.2) and setslabel{eq:foo}. I do not think I have to label all tagx'es there ever will be.– cis
May 19 at 17:20
in that case you would only want to do the
labelin the case the argument was provided, as it is above if you don't supply the option you end up withlabel{}which is an error.– David Carlisle
May 19 at 17:22
@DavidCarlisle I changed your solution to
% tagx[<label, optional>] % normal tag inline newcommand{tagx}[1]{refstepcounter{equation}(theequation)label{#1}}That is wrong?– cis
May 19 at 17:38
yes that is wrong as you do
label{}if the argument is not provided.– David Carlisle
