To summarize the latest improvements and modifications to the `:export'
attribute...
The attribute supports one or more elements separated by a space. Each
element can be any of the following signs: "*" (export only the
content), "-" (do not export), "=" (export the rest normally), "=*"
(export the rest, but only the content), "=-" (do not export the rest).
Additionally, backend names can be given explicitly, alone or
accompanied by the "*" or "-" signs, that is (where "backend" equals the
name of the backend):
backend: export normally for that backend and its derived backends;
backend-: do not export for that backend or its derived backends.
backend*: export only the content for that backend and its derived
backends.
Some examples with valid combinations:
@foo[:export *]{lorem ipsum}
==> export only the content
@foo[:export -]{lorem ipsum}
==> do not export
@foo[:export latex-]{lorem ipsum}
==> do not export to LaTeX
@foo[:export latex- html* =]{lorem ipsum}
==> do not export to LaTeX, export only the content to html and export the
rest normally.
@foo[:export latex =*]{lorem ipsum}
==> export normally to LaTeX but export only the content to the rest
@foo[:export latex =-]{lorem ipsum}
==> export normally to LaTeX and not export to the rest
And below is a complete example based on a possible use case that Max
had exposed:
