Hi, I wonder if it's necessary to manually load the MetaPost variables using LoadPageState. Some of them are static and do not require an update on each page, e.g. NOfPages, but many of them might change on each page, e.g. OnOddPage, PageNumber, TextWidth. Forgetting to use LoadPageState easily results in perfectly valid code producing wrong results, which might not be hard to spot. Example:
\setuplayout [width=10cm]
\showframe
\starttext
\startMPcode
fill unitsquare xyscaled (\the\textwidth, 2cm);
\stopMPcode
\startMPcode
fill unitsquare xyscaled (TextWidth, 2cm);
\stopMPcode
\startMPcode
LoadPageState;
fill unitsquare xyscaled (TextWidth, 2cm);
\stopMPcode
\stoptext
I assume it's too inefficient to load the page state automatically
for each graphic. However, loading the page state automatically is
simple:
\startMPinitializations
LoadPageState;
\stopMPinitializations
