I'm having problems with an environment definition. Using the xparse and
etoolbox packages, I have created the environment syriacpoem in my .sty
file. It is defined as
%%%%%%
\DeclareDocumentEnvironment{syriacpoem}{so}{%
\ifbool{...@kashpoem}{\begin{syrjust}}{}%
\begin{syriac}%
\ifstrequal{#2}{estr}{\estrfont}{}%
\ifstrequal{#2}{serto}{\sertofont}{}%
\ifstrequal{#2}{madnha}{\madnhafont}{}%
\ifstrequal{#2}{east}{\madnhafont}{}%
\ifstrequal{#2}{estrangelo}{\estrfont}{}%
\ifstrequal{#2}{estrangela}{\estrfont}{}%
\IfBooleanTF #1 {\begin{traditionalpoem*}}{\begin{traditionalpoem}}}{%
\IfBooleanTF #1
{\end{traditionalpoem*}}{\end{traditionalpoem}}\end{syriac}%
\ifbool{...@kashpoem}{\end{syrjust}}{}}
%%%%%%
The boolean x...@kashpoem is true if word-stretching justification is
required. The environment syrjust provides that justification using a
version of Jonathan Kew and Fr Michael Gilmary's implementation with
interchartoks shown on this list. The syriac environment is from
polyglossia, ensuring RTL and a Syriac font, and it is followed by
optional font switches for other Syriac fonts. Then either the starred
or unstarred version of bidipoem's traditionalpoem environment is turned
on depending on the presence or absence of a star in the document
command. The end of environment closes all these nested environments in
order.
This new environment works as expected in normal tests. However, as I
came to document it, I wanted to give an example in a framed float in my
package documentation. However, the new environment breaks inside the
float. My framed box uses the fancybox package and is defined as
%%%%%%
\newenvironment{example}[1]%
{\begin{figure}[h]\begin{center}\begin{Sbox}\begin{minipage}{#1}}%
{\end{minipage}\end{Sbox}\ovalbox{\TheSbox}\end{center}\end{figure}}
%%%%%%
Obviously, something in the environment is upsetting my example box. If
I replace my syriacpoem environment with the nested environments it
calls, it works perfectly. So, there's nothing wrong with what the
environment does, just in how it does it. The lengthy section of the log
dealing with this is below. Can anyone suggest how to fix this?
Thanks,
Gareth.

A number should have been here; I inserted `0'.

look up `weird error' in the index to The TeXbook.)
