Hi, Line numbering does not respect the parameters given with \startlinenumbering. For example: \definelinenumbering [test] \starttext \startlinenumbering[test][color=blue,align=flushright,distance=0.5em] \input knuth \stoplinenumbering \page \setuplinenumbering [test][color=blue,align=flushright,distance=0.5em] \startlinenumbering[test] \input knuth \stoplinenumbering \stoptext Aditya

I think that the state at the end of the page flush is used, rather than the state at the beginning of line numbering. An example illustrating this: \definelinenumbering [test] \starttext \startlinenumbering[test][color=blue,align=flushright,distance=0.5em] \input knuth \stoplinenumbering \setuplinenumbering [test][color=blue,align=flushright,distance=0.5em] \startlinenumbering[test] \input knuth \stoplinenumbering \setuplinenumbering [test][color=red,align=flushright,distance=0.5em] \stoptext (Both snippets have red line numbers!)

Hi,
Line numbering does not respect the parameters given with \startlinenumbering. For example:
Line numbering is a delayed operation. As they are handled when the page is constructed the settings of that moment apply. In practice only the start key is handled when you pass settings to \start.... (the only reason for having the second argument is number start/restart etc). If you want different renderings, the best is to define a specific instance of line numbering. Maybe a future version will be more clever.

A little background: In the initial version of the vim module, I used to do line numbering manually (each line started with \NL macro, which expanded to a number in an appropriate style depending on whether line numbering was enabled or not. When I rewrote the module to use the filter module, I also rewrote the line numbering mechanism to use ConTeXt's inbuilt line numbering macros, but I cannot get them to work. Consider the following example. I want to define an environment, which, amongst other things does line numbering. I want the user to control the style and color of line numbering, so I define keys numberstyle and numbercolor, which are then passed on to the line numbering macros. The most obvious implementation of this does not work. \definenamespace [whatever] [ type=module, name=whatever, command=yes, setup=yes, parent=whatever, ] \appendtoks \definelinenumbering [\currentwhatever] [ color=\whateverparameter{numbercolor}, style=\whateverparameter{numberstyle}, ]% \setvalue{start\currentwhatever}{\dostartwhatever[\currentwhatever]}% \setvalue{stop\currentwhatever}{\dostopwhatever}% \to\everydefinewhatever % For illustration. The actual macro is more complicated. \def\dostartwhatever[#1]% {\startlinenumbering[#1]} \def\dostopwhatever {\stoplinenumbering} %%%% \definewhatever[testing][numbercolor=red,numberstyle=bold] \starttext \starttesting \input knuth \stoptesting \stoptext When I run it, the line number is not styled. Any idea on what I can do differently? Aditya

You assume \definelinenumbering has a second argument for the settings but this isn’t the case and you need \setuplinenumbering to set them. Wolfgang

D'oh.

I also needed to change \setvalue to \setevalue in the example, and add an \expanded to get it to work. \definenamespace [whatever] [ type=module, name=whatever, command=yes, setup=yes, parent=whatever, ] \appendtoks \definelinenumbering [\currentwhatever]% \expanded{\setuplinenumbering [\currentwhatever] [ color=\whateverparameter{numbercolor}, style=\whateverparameter{numberstyle}, ]}% \setevalue{start\currentwhatever}{\dostartwhatever[\currentwhatever]}% \setevalue{stop\currentwhatever}{\dostopwhatever}% \to\everydefinewhatever % For illustration.

In MkIV \setuevalue is better the \setevalue and \normalunexpanded is faster than \expanded. The problem in your approach is that you can only set the style and color value with \definewhatever where I think it’s better to use \setupwhatever. \unprotect \installnamespace {whatever} \installcommandhandler \????whatever {whatever} \????whatever \appendtoks \definelinenumbering[\currentwhatever]% \to \everydefinewhatever \appendtoks \setuevalue{\e!start\currentwhatever}{\whatever_start[\currentwhatever]}% \setuevalue{\e!stop\currentwhatever }{\whatever_stop }% \to \everydefinewhatever \appendtoks \normalexpanded{\setuplinenumbering [\currentwhatever] [\c!color=\whateverparameter\c!numbercolor, \c!style=\whateverparameter\c!numberstyle]}% \to \everysetupwhatever \unexpanded\def\whatever_start[#1]% {\begingroup \edef\currentwhatever{#1}% \startlinenumbering[\currentwhatever]} \unexpanded\def\whatever_stop {\stoplinenumbering \endgroup} \protect \definewhatever[testing][numbercolor=red,numberstyle=bold] \setupwhatever [testing][numbercolor=blue] \starttext \starttesting \input knuth \stoptesting \stoptext Wolfgang

Thanks for both the tips! Aditya
