How to get the number of lines of a paragraph?

How to get the number of lines of a paragraph?

[Wei-Wei Guo]

Dear all,

I need to draw underlines under a paragraph. The number of underlines is
determined by the number of lines of the paragraph. For example:

If the paragraph have one line:

   text of paragraph, blur blur.
   ----------------------------------------------------------

If the paragraph have two lines:

   text of paragraph, blur blur blur blur blur blur blur blur
   ----------------------------------------------------------
   blur blur blur blur blur blur blur blur.
   ----------------------------------------------------------


Another question: How can I set the header of the pages of contents?

Thanks!

Best wishes,
Wei-Wei

It is not what I want. First, the underline is too close to the text. I need
to be able to manipulate the distance between the underline and the text.
Second, the underline of the last line has the same length with the last
line of the text. The underlines should be all the same length.

I don't mean the head of contents. I mean the header of the page, which is
the opposite concept to footer. It seems the head of the contents is not
treated as chapter. I tried \getmarking, but it doesn't work.

Hi,

May be this can help you.

You can control the distances by setting up the params of
"currentpicture shifted" and linespace.

Re: How to get the number of lines of a paragraph?

[Wei-Wei Guo]

It works, thanks!

Can \startunderline be put into a table or a tabulate? I want to implement
thing like this:

   \startbuffer[chinesetitle]
     \startunderline
     基于成本的钉耙强度与应用——东方视角分析
     \stopunderline
   \stopbuffer

   \startbuffer[englishtitle]
     \startunderline
     Cost Based Rake Strength and Application: An Oriental View
     \stopunderline
   \stopbuffer

   \starttabulate[|l|l|]
   \NC 中文论文题目： \NC \getbuffer[chinesetitle] \NC \NR
   \NC 英文论文题目： \NC \getbuffer[englishtitle] \NC \NR
   \stoptabulate

Of cause, the codes do not work. Is there any alternative way?


Best wishes,
Wei-Wei

You don't need this, \definetextbackground creates start/stopunderline  
itself.

location=paragraph

The context term is headertext and \title is used for the header,
try \getmarking[title].

Re: How to get the number of lines of a paragraph?

[Wei-Wei Guo]

Hi Wolfgang,

I tried many ways, but could not make the following effect:

   Title Head: Here is text, blur blur blur blur blur blur
               -------------------------------------------
               blur blur blur blur
               -------------------------------------------

I tried \starttabulate, \starttable, \setupTABLE, and \definedescription
with \underline{} and \startunderline.

- Tabulate will get error.
- Table do not show underline.
- Natural table displays the underline with only half length as the text
   line's. And the vertical positions are also not right.
- Description seems more promising, but the head will be about one line
   height higher than the text with underline (I use location=left).

Could you help me with it?


Wei-Wei

You can need a p column in table/tabulate.

The wrong position of the line is a bug, make a bug report and use Li  
Yanruis
fix for the moment.

\definetextbackground
   [underline]
   [location=paragraph,
    alternative=1,
    background=,
    frame=off]

\starttext

\starttabulate
\NC Title Head \EQ \underline{Here is text, \dorecurse{20}{blur }} \NC 
\NR
\stoptabulate

\stoptext

Thanks! The p solves my problem.
