Weird background colors in autogenerated index

Weird background colors in autogenerated index

[Jan Tosovsky]

[-- Attachment #1: Type: text/plain, Size: 397 bytes --]

Dear All,

since LuaTeXt 0.81 my back-of-the-book index (register) is generated with
strange background colors. The index title is typeset in yellowish
background and the left column of the last index page has a blue background,
see the attachment.

I've thought I reported it, but it is still there even in 0.95. It was fine
in the version 0.80.

Could this be somehow eliminated?

Thanks, Jan

I've published both the ConTeXt source and the final PDF here:

Jan,

here you have the minimal sample:

  \showgrid
  \starttext
  a\index{b}
  \completeindex
  \stoptext

Comment the first line and colors background colors will disappear.

Don’t know whether it is a bug or not, but this is only related to
\showgrid.

I hope it helps,

Pablo

indeed, it's tracing related (no bug)

a good catch, Pablo, thanks.

> indeed, it's tracing related (no bug)

My idea is to have a single PDF source to showcase some ConTeXt features, where displaying the grid is handy, yet allow disabling the grid on demand. 

So any visible \showgrid related issues, which cannot be switched off together with the grid layer, are unacceptable ;-)

Is there any chance to improve this a bit?

Thanks, Jan

well, with tracing one gets what's provided .. after all it's tracing, 
so 'unacceptable' is a kind of unacceptable demand

> Is there any chance to improve this a bit?

currently not but you can influence the grid a bit:

   \showgrid[reset,...]

options can be seen with

   context --extra=setups grid

You're lucky that it's only a few lines to add 'columns' options (so in 
some upcoming beta you have to mess with 'reset' and whatever else).

I am completely lost. I found page-grd.mkiv, but I have no idea what to tweak here.

By simple putting \showgrid[reset] at the beginning of the document no grid is shown, but those colored areas are present.

I am giving it up.

Jan

You can’t disable the backgrounds with the current beta but in one of 
the coming betas
you can use the "reset" key to disable the grid visualizers and enable 
afterwards only
the grid lines.

Ah, thanks for clarification. No problem.
