naming of labels: Is »()« allowed?

naming of labels: Is »()« allowed?

Dear ConTeXt folks,


in ConTeXt I like how I can choose arbitrary names for label and
reference them. I think some time ago it was possible to also use »()«.
This does not work anymore with

        ConTeXt  ver: 2011.11.25 21:29 MKIV  fmt: 2011.11.25  int: english/english

and the following message is in the log file.

        references      > unknown reference [][(N)]


        \definereferenceformat[eqref][left=(,right=)]
        
        \starttext
        \placeformula[(N)]
        \startformula
        	\Pr\{N = n\} = \Pr\left\{ \min_{1 ≤ k ≤ n} S_k > 0 \right\} = p_n^{(1)}
        \stopformula
        
        Is it working? \eqref[(N)]
        
        \CONTEXT\ \contextmark\ \contextversion
        \stoptext


Thanks,

Paul

\definereferenceformat[eqref][left=(,right=)]

\starttext
\placeformula[(N)]
\startformula
	\Pr\{N = n\} = \Pr\left\{ \min_{1 ≤ k ≤ n} S_k > 0 \right\} = p_n^{(1)}
\stopformula

Is it working? \eqref[(N)]

Hi Paul,

It seems that the left parenthesis causes trouble when giving a label to a reference:

       \definereferenceformat[eqref][left=(,right=)]

       \starttext
       \placeformula[N)]
       \startformula
       	\Pr\{N = n\} = \Pr\left\{ \min_{1 ≤ k ≤ n} S_k > 0 \right\} = p_n^{(1)}
       \stopformula

       This works: \type{\eqref[N)]} gives \eqref[N)].
       
          \starttext
       \placeformula[(N]
       \startformula
       	\Pr\{N = n\} = \Pr\left\{ \min_{1 ≤ k ≤ n} S_k > 0 \right\} = p_n^{(1)}
       \stopformula

       This does not work: \type{\eqref[(N]} gives \eqref[(N].
    
This is not really an issue, since it is not necessary to name a label « (N) » or « (N »…

Best regards: OK

indeed, formula:n-lparent makes more sense then

keep in mind that references are parsed .. think of a comma separated 
list of:

component:::inner
component:::inner
component:inner
special(operation{argument,argument})
special(operation)
special(\operation)
special()
inner{argument}
inner{\argument}
outer::
outer::inner
outer::special(operation{argument,argument})
outer::special(operation{argument,\argument})
outer::special(operation)
outer::special(\operation)
outer::special()
outer::inner{argument}
special(outer::operation)

so, letters, digits and dashes and single colons are quite ok in tags
