Database module and command key

Database module and command key

[Wolfgang Schuster]

Hi Hans,

why has the meaning of the command key changed in MkIV?


In MkII you can define a command which has as many argument as entries in the list.

% engine=pdftex

\usemodule[database]

\starttext

\define[3]\TestCommand{\ruledhbox{#1:#2:#3}}

\defineseparatedlist[test][command=\TestCommand]

\starttest
1,2,3
\stoptest

\stoptext


In MkIV the argument of the command key is applied to each entry in the list
and you can’t grab all entries with a single command.

\usemodule[database]

\starttext

\define[1]\TestCommand{\ruledhbox{#1}}

\defineseparatedlist[test][command=\TestCommand]

\starttest
1,2,3
4,5,6
\stoptest

\stoptext

Wolfgang

Probably because it went unnoticed (I'm not using it myself). You can 
patch this:

                             if j == 1 then
                                 context(command)
                             end
