Modes
Often you'd like to publish different versions of a document, say a presentation and a handout or a student's and a teacher's version.
ConTeXt supports such filtering with its modes:
ConTeXt is a great TeX macro package. \startmode[handout] % The following text will only appear in the handout It’s based on PlainTeX like the better known LaTeX. \stopmode
\startnotmode[print] Here's a link to my homepage: \url[...] \stopnotmode
...mode and ...notmode let you filter your content sufficient in most cases. You can also give several modes like \startmode[handout,print].
Modes are also a convenient way to comment out sections (typical: "obsolete" mode).
You can typeset the different modes like:
texexec myfile --mode=handout --result=handout.pdf
You don't need the --result, but otherwise you'd get the same filename for both modes.
Modes are extremely powerful when applied to text. However, they can be applied to configuration problems as well. A user wanted to generate different versions of the same file with different fonts:
\startmode[palatino] \usetypescript[adobekb][8r] \usetypescript[palatino][8r] \setupbodyfont[palatino,12pt] \stopmode \startmode[times] \usetypescript[adobekb][8r] \usetypescript[postscript][8r] \setupbodyfont[postscript,12pt] \stopmode \starttext \input knuth \showfontstrip \stoptext
And run with one of the following:
texexec --pdf --mode=palatino filename texexec --pdf --mode=times filename
