Hi all, Five years ago I requested an instant preview option for ERT in: http://www.lyx.org/trac/ticket/1723
Uwe just marked this as wontfix, and I disagree with that decision. Uwe wrote: >>> A general preview for ERT is impossible because there are countless LaTeX >>> packages available. Yes, but any extra packages should be specified in the preamble. Since there are many ERT for which a preview is possible, shouldn't LyX give users the option? >>> LyX is designed that you don't need to learn LaTeX and to avoid LaTeX >>> errors. But when you use ERT certain LaTeX-packages have to be installed >>> that are not available on every PC. This would lead to LaTeX errors. Sure the preamble and ERT give users the possibility to require unsupported packages and break stuff. But this seems like an argument against ERT in general. What does this have to do with an instant preview? >>> Another goal of LyX is to give the user a visual feedback how his document >>> will look, but not how it will look _exactly_. This is our WYSIWYM >>> philosophy. http://en.wikipedia.org/wiki/WYSIWYM. If I use ERT to generate some exotic figure, I'll want to see how it looks without rendering my entire document. I don't see how this violates WYSIWYM. Both JMarc and Jurgen seem to think this feature could be useful. I'd like to see some clearer justification, or reopen the ticket. What do others think? Thanks! -Ben
