problem with def

problem with def

[John Culleton]

In plain pdftex I can define a string thus:
\def\booktitle{My Book Title}

and then reuse it later as
\rightline{\bf\booktitle}
 But in Context when I use
\rightaligned{\bf\booktitle}

it errors on the tag \booktitle

I tried \the\booktitle but that didn't work either.

This definitely should work, so you should post a minimal
example (are you defining \booktitle inside a group?)

This should not work.

Best wishes,
Taco

When I put together an example in a single file it works. In my 
more extended example the fonts are defined in fonts.tex, the
value of the string is defined in macros.tex and the usage is 
defined in half.tex. There is a \startstandardmakeup 
\stopstandardmakeup. Here is my master file:
----------------------------------%Example book.tex file for novel.

\input macros.tex
\input fonts.tex
\starttext
\startfrontmatter
\startstandardmakeup
\input half.tex
\input title.tex
\input copy.tex
%\input ded.tex
%\input ack.tex
%\input content.tex
\stopstandardmakeup
\stopfrontmatter
\startbodytext
\input body.tex
\stopbodytext
\startbackmatter
\stopbackmatter
\stoptext
---------------------------------
 
Since I can't come up with a brief example of the problem I will 
start commenting things out, moving things from file to file and 
see what happens.

This feature is a nice to have and not a got to have. I can always 
just retype the title wherever it occurs. But it is a head scratcher.

no problem here with last current

\def\booktitle{My Book Title}
\showframe
\starttext
then reuse it later as
\rightline{\bf\booktitle}
 But in Context when I use
\rightaligned{\bf\booktitle}
\stoptext

Hi Luigi,

Are you sure? If I compile exactly the lines above, I don't get the intended righ aligned title: it seems that one needs a blank line before \rightalign, that is:

\def\booktitle{My Book Title}
\showframe
\starttext
then reuse it later as

\rightline{\bf\booktitle}

But in Context when I use

\rightaligned{\bf\booktitle}
\stoptext

Best regards: OK

Yes, can be.  I meant  "no errors" not "it looks ok"

I suggest to use ConTeXt’s \setvariables

\setvariables[book][title=My Book Title]

\starttext
\rightaligned{\bf\getvariable{book}{title}}
\stoptext
