Re: [NTG-context] Semi-verbatim - preserve whitespace - don't escape characters
2007/12/7, [EMAIL PROTECTED] [EMAIL PROTECTED]: Hi. I'm working on a document processor that has multiple backends for different output formats (XHTML, nroff, plain text, ConTeXt). The processor uses s-expression syntax with commands such as: (para this is a paragraph) The various backends then convert this statement in their own way (using p/p tags in XHTML, for example). There is one command that allows rendering of external files based on whatever backend is selected: (render file) The XHTML backend includes file, escaping all 'illegal' characters such as , , etc. The ConTeXt backend reads the file and also escapes characters, placing their TeX equivalent in the output - $\}$, $\backslash$ etc. Both backends place the contents of file directly in the output, they don't, for example, use the object tags in XHTML, or any ConTeXt file inclusion directives. This is desirable for many reasons that are out of scope for this post... The problem I am having is that one may do this: (para-verbatim (render file)) The para-verbatim tag is meant to preserve whitespace in the output. For example, this becomes: precontents of file/pre in the XHTML output. Unfortunately, I've hit a wall when it comes to the ConTeXt equivalent: The ConTeXt backend reads in file and prints it to the output, escaping all reserved TeX characters, as mentioned earlier, but unfortunately there doesn't seem to be the equivalent of: \preservewhitespace contents of file \stoppreservingwhitespace \starttyping is too heavy handed in that it also escapes characters rather than just preserving whitespace (they've already been escaped by my document processor, as mentioned earlier). What I need is a directive that says preserve whitespace but does not escape reserved TeX characters. Does any such thing exist in ConTeXt? Unfortunately, I'm inexperienced with TeX so I don't know how feasible this is. \startlines verbatin text \stoplines Wolfgang ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : https://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___

I know but setup keys are the best way to change the layout of
environemnts and keep the document clean. Using a converter is no
answer why you should't you this mechanism and write the styyle change
in the document and not in preamble.
\startlines

As Dexter? already mentioned, he writes the escaped commands in the
document \undefinedmacro will end up as \tex{undefinedmacro} or
\type{\undefinedmacro} in the output file.
