Annotation of loncom/html/adm/help/tex/Authoring_HTML_vs_Tex.tex, revision 1.4

1.1       bowersj2    1: \label{Authoring_HTML_vs_Tex}
                      2: LON-CAPA renders resources in several formats, including on the web in
                      3: HTML and in LaTeX for renderings designed to be printed.
                      4: 
                      5: When creating problems, it is possible to use LaTeX directly by using
                      6: the <m> tag\index{m tag}\index{tag, <m>} (see
1.3       felicia     7: \ref{Authoring_Output_Tags}). Anything between the <m> tag in a resource
1.1       bowersj2    8: will be interpreted as .tex.
                      9: 
                     10: However, this should be used as a last resort for when you wish to do
                     11: something that is impossible to do in HTML. LON-CAPA will convert to
                     12: and from LaTeX and HTML whenever necessary, and it is much easier (and
                     13: therefore more likely to work) to convert HTML to LaTeX then to go the
1.2       www        14: other direction, because HTML is so much simpler than LaTeX. 
1.1       bowersj2   15: 
                     16: Thus, given the choice of 
                     17: 
                     18: \texttt{H<sub>2</sub>O}
                     19: 
                     20: or 
                     21: 
1.4     ! bisitz     22: \texttt{$<$m$>$\$ H\textbackslash{}subscript\{2\}O \$$<$/m$>$}
1.1       bowersj2   23: 
                     24: it is better to use the HMTL version.
                     25: 
                     26: A necessarily-incomplete list of capabilities: LON-CAPA can convert
                     27: HTML tables in LaTeX tables, images into LaTeX images, LaTeX symbols
                     28: into HTML, and LaTeX math into HTML (though it does not usually look
                     29: as good as LaTeX).
                     30: 
                     31: If you really wish to have the web rendering and the LaTeX rendering
                     32: do something different, perhaps because the automatically generated
                     33: LaTeX->HTML conversion did not do what you wanted, you can surround
                     34: your LaTeX with <tex> </tex>\index{tex tag}\index{tag, <tex>} tags,
                     35: and your HTML version with <web> </web>\index{web tag}\index{tag,
                     36: <web>} tags. The stuff placed between the <tex> tags will only show on
                     37: the LaTeX rendering of the resource, and the stuff placed between the
1.2       www        38: <web> tags will only show on the HTML web rendering of the resource.
