block with different formatting per line?

block with different formatting per line?

[Ingo Hohmann]

Hi,

is it possible to define a block, where lines are automatically 
formatted differently?
For example:
first line in caps,
second in bold,
others normal.

Is this possible? And how?


Kind regards,

Ingo

If you mean input lines, then yes.  But if you mean output lines, then I don't know.  It seems a well-defined task, but a hard task judging by how the line-breaking algorithm is described by Knuth.  I'll leave that question to experts.

Here's a way to process the input lines.  If there's a counter that counts the line number, there would be another way; but I couldn't find out that there was a counter.  There may be better ways anyway.

\define\FirstLine{\let\myLine\SecondLine\sc}
\define\SecondLine{\let\myLine\OtherLine\bf}
\define\OtherLine{\tf}
\definelines[doMyLines][command=\myLine]
\def\startMyLines{\let\myLine\FirstLine\startdoMyLines}
\def\stopMyLines{\stopdoMyLines}

\starttext

\startMyLines
First line in caps,
Second in bold,
Others normal.
Others normal.
Others normal.
\stopMyLines

And again:

\startMyLines
First line in caps,
Second in bold,
Others normal.
Others normal.
Others normal.
\stopMyLines

\stoptext

Yes, that's exactly what I meant, and you even answered my next 
question, too.

Thank you!

As I said that works, but while trying to understand this, I found that 
the documentation for \definelines doesn't mention the "command=" 
option. On the other hand it does mention "align=" and this doesn't 
work. Neither does \setuplines.

I always get "undefined control sequence".

\definelines[doFirstBoldRight][command=\myLine]
\setupdoFirstBoldRight[align=flushleft]

OR

\definelines[doFirstBoldRight][align=flushleft,command=\myLine]

gives the same error.

Do you have any idea what I am doing wrong?


Thank you in advance,

Ingo

Make a complete example.

BTW: I suggest to use my Lua example from the other thread.

I thought I could get away without it, because it's practically the 
answer to my question, just with alignment.
For some reason, now that I started from scratch to show the example, it 
works.

\define\FirstLine{\let\myLine\SecondLine\sc}
\define\SecondLine{\let\myLine\OtherLine\bf}
\define\OtherLine{\tf}

% this align here didn't work
\definelines[doMyLines][align=flushright,command=\myLine]

% and this setup doesn't
%\setupdoMyLines[align=flushright]

\def\startMyLines{\let\myLine\FirstLine\startdoMyLines}
\def\stopMyLines{\stopdoMyLines}

\definelines[right][align=flushright]

% I get an error here, too.
%\setupright[align=flushright]

\starttext

\startright
test
\stopright

\startMyLines
First line in caps,
Second in bold,
Others normal.
Others normal.
Others normal.
\stopMyLines

\stoptext

> BTW: I suggest to use my Lua example from the other thread.

When I looked at it first, it was in the middle of the night. And it 
looked a bit over the moon for me. Now I think I can grab it, and it 
looks _very_ powerfull.


Thank you.

My #1 "Wish List" item for ConTeXt is /allowing/ "stylesheets" at the 
paragraph level. That would allow closer correspondence with what 
CSS/CSS3, Scribus, ODT, EPUB3 &al do and make it much easier to write 
transformation scripts whether XSLT, lua code, Perl code or whatever 
favorite tool one wishes to use.

I envision something like (psuedo code):

\setupstylesheet[myparagraphstyle]
   [font=AccanthisADF,
   fontsize=12pt,
   fontstyle=italic,
   alignment=justified,
   frame=no,
   color=blue,
   width=\textwidth,
   &c ....
   ]

\starttext

   \startparagraph[style=mystylesheet]
     \input tufte
   \stopparagraph

   \input knuth

\stoptext

The output would have the tufte quote formatted according to my 
stylesheet and knuth in whatever the global style is.

The style parameter in the start/stop paragraph would, of course, be 
/optional/ so existing documents would be unchanged from current 
behavior but allow the introduction of paragraph styles.

A few of these values can be set for certain paragraphs with the new \defineparagraph command.

framedtext already does most of this (except that it makes the paragraphs 
unbreakable across pages). I don't remember if backgrounds has all the 
relevant keys.

Here's a way to process the input lines.  If there's a counter that counts the line number, there would be another way; but I couldn't find out that there was a counter.  There may be better ways anyway.

\define\FirstLine{\let\myLine\SecondLine\sc}
\define\SecondLine{\let\myLine\OtherLine\bf}
\define\OtherLine{\tf}
\definelines[doMyLines][command=\myLine]
\def\startMyLines{\let\myLine\FirstLine\startdoMyLines}

As I said that works, but while trying to understand this, I found that the documentation for \definelines doesn't mention the "command=" option. On the other hand it does mention "align=" and this doesn't work. Neither does \setuplines.

I figured it out from the source, spac-lin.mkiv.  One might see there that the "align" key does not seem to be processed; it s a relic from a previous version of ConTeXt, I suppose.  Many macros have a "command" key, which usually seems to be a method for customizing the basic unit, in this case a line.  (The source is written in a certain style that makes it possible often to figure things out, even when the wiki is not up-to-date.  I say "possible" but not always easy.  And there's always this maillist.)
