index issues

index issues

[Henning Hraban Ramm]

Hello again,

still struggling with indexes.

(1)
\setupregister’s before and after go around the indicator.
e.g. \setupregister[][indicator=no,after={XX}]
never shows that XX, since after is only used after the indicator, while before also works without.

I was hoping for a hook at the end of a section (to add \testcolumn, \blank etc. to work around no.2). Is there any?


(2)
Page/column breaking is odd in that the preferred breaking point seems to be one entry too early, i.e. the last entry of one letter end up in the next column and the previous column is one line too short.
It doesn’t change with balance=yes/no.

E.g.

p.1
A   A
A   A
A
A   B
A   B
A   B
A      <<<< !?

p.2
B   C
B   C
B   C
    C
C   
C   D
C   D


(3)
(How) can I otherwise influence page/column breaking? E.g.
- always keep multi line entries together
- break before or after some entry


(4)
Is it possible to combine entries from \index and \startregister[index]?

If I use \start/stopregister and have the same index entry within the range or on the same page, I get duplicate pages or page ranges, like 10-12 from \startregister and additionally 11, 12-13 from \index entries, makes at the moment 10-12, 11, 12-13 instead of just 10-13.



I’ll prepare MWEs, but maybe you can answer some of these without?

Thank you in advance,

Hraban

Hello Hraban!

Without MWE try \showinjector
<https://wiki.contextgarden.net/Command/showinjector> and \setinjector
<https://wiki.contextgarden.net/Command/setinjector>.

Jano, Duncan, thank you!

Injectors were mentioned recently, of course I forgout about them... Will try.

Best, Hraban

It doesn’t work for me:

lua error       > lua error on line 24 in file inhalt/99anhang.tex:

registered function call [421]: ...-06/tex/texmf-context/tex/context/base/mkiv/typo-inj.lua:63: attempt to index a nil value (field '?')
stack traceback:
	...-06/tex/texmf-context/tex/context/base/mkiv/typo-inj.lua:63: in function <...-06/tex/texmf-context/tex/context/base/mkiv/typo-inj.lua:57>
	(...tail calls...)

23     \setinjector[Person][10][{\column}]
24 >>  \showinjector[Person]


Regardless what I try as parameter of \showinjector (e.g. register, index, my own registers, one or a list) and where (in the environment or before \placeregister), I always get this error.

Bug?

I don't think \showinjector needs an argument. My MWE when I was looking at
this has just \showinjector after the register definition but before the
\setinjector[...] commands.

Docs say otherwise.
Without argument, I don’t get an error, but also nothing happens.

If one of the \index{D...} lines is commented in the following example, the last D entry goes into the second column, the columns get balanced, and the second line of the last K entry is broken to the next page.
If you uncomment that line, it looks as intended (no balancing, full left column).
What’s wrong? Can I influence this e.g. with penalties?

(Screenshots were too big...)

index issues

[Henning Hraban Ramm]

(1)
If I get the same index entry two or more times on a page, sometimes with processor formatting, sometimes not, how can I control which version takes precedence?

Actual use case: index entries from footnotes should be italics, while those from the main text stay upright.
Now, if there is an entry from the main text, the entry from the footnote doesn’t matter. Is it possible to control that?
I wouldn’t like to sort out the cases manually and remove the entries from the footnotes – there are 981 footnotes in this book, and there are 15 pages of index entries.

I’m using a macro (I suppose you’ll remember; I left out the Lua table lookup for unified entries):

\defineprocessor[kursiv][style=italicface]

\define[1]\nIndex{\doifmodeelse{*footnote}{%
  \expanded{\index[kursiv->]{#1}}}%
}{%
  \expanded{\index{#1}}}%
}}


(2)
Can I avoid linebreaking of page ranges in \placeindex?

E.g. in

Knuth, Don   23, 35-
  37, 40

I’d like to keep 35–37 together (break before 35).
