I am having some trouble understanding how to implement a new
environment in an existing .layout file. The documentation covers the
principle, but not the detail, especially about how to enable other
environments (like lists) *inside* the one I am implementing, and how to
get LyX to prompt for any arguments required in my environment.
I have defined and tested the environment in LaTeX, and I then add to
the .layout file:
Style Foo
LatexType Environment
LatexName foo
ParSep 0.5
Font
Size Small
> Series Normal
EndFont
Preamble
\newenvironment{foo}
{\begin{quotation}\small\raggedright\noindent\ignorespaces}
> {\par\end{quotation}}
EndPreamble
End
When I open a .lyx file, the entry for a Foo is there in the menu, and I
can add a few words and paragraphs and it correctly exports:
\begin{foo}
a few words
and paragraphs\end{foo}
All well so far.
But an environment should be able to contain all kinds of other
environment, like lists. If I try to add an itemized list between the
two paragraphs above, the exported LaTeX shows that LyX has terminated
the foo environment prematurely, inserted the list *outside* the
environment, and then created a new instance of the foo environment to
hold the second paragraph:
> \begin{foo}
> a few words\end{panel}
> \begin{itemize}
> \item blort\end{itemize}
> \begin{panel}
> and paragraphs\end{foo}
How do I tell LyX that lists (for example; and much other stuff) is
permitted inside a Foo environment? Is there a setting or switch that
tells LyX to allow nested environments globally, or does it have to be
done on an environment by environment basis?
Bonus question: I will eventually want to extend the environment to add
a box and shaded background, allowing the user to specify width and
color in mandatory arguments to the Foo environment. Writing the LaTeX
definition for the Preamble is easy; but how do I tell LyX that the
environment has two arguments? I can see that an Inset affords the
option to add tokens or values, but I can't see how to make one
compulsory, so that it pops up the moment you add a Foo from the menu.
Final plea: I have been unable to find a formal list of all the keywords
for a .layout file, with their syntax and application. Does such a list
exist yet?
