Dear all, after installing the latest beta I tried to compile my old sources, but the metapost pass called from within a pdfetex run stopped with the error message: ! Equation cannot be performed (numeric=boolean). <to be read again> ; l.24 spotcolors := true ; Looking at the mpgraph file I see the following line: if unknown context_spec : input mp-spec ; fi ; and in my version of mp-spec spotcolors is declared to be boolean. Indeed, when I run 'mpost filename-mpgraph' I get no error message and all mp-* files are included. Any hint on where context_spec et al are set? Groet Johannes -- Johannes Hüsing There is something fascinating about science. One gets hannes@ruhrau.de such wholesale returns of conjecture from such a trifling investment of fact. Mark Twain

Dear all,

! Equation cannot be performed (numeric=boolean). <to be read again> ; l.24 spotcolors := true ;

Looking at the mpgraph file I see the following line:

if unknown context_spec : input mp-spec ; fi ;

and in my version of mp-spec spotcolors is declared to be boolean. Indeed, when I run 'mpost filename-mpgraph' I get no error message and all mp-* files are included.

Any hint on where context_spec et al are set?

(1) from now on, context's mp files are under /metapost/context/base, so remove any file in the parent path (2) did you make the metafun format (normally texexec --make --alone does the job) (3) looks like a mismatch between context (more recent) and older mp code [btw, spot colors are discussed in the new color manual] Hans ------------------------------------------------------------------------- Hans Hagen | PRAGMA ADE | pragma@wxs.nl Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: +31 (0)38 477 53 69 | fax: +31 (0)38 477 53 74 | www.pragma-ade.com ------------------------------------------------------------------------- information: http://www.pragma-ade.com/roadmap.pdf documentation: http://www.pragma-ade.com/showcase.pdf -------------------------------------------------------------------------

I have read that much, but after unzipping this archive (cont-tmf.zip with an MD% sum of 9c35ee4da8259cd231717a0ca321d472) the files are in metapost/context, but not in metapost/context/base. Shall I create the directory and move the files manually?

(2) did you make the metafun format (normally texexec --make --alone does the job)

Yes.

...

(3) looks like a mismatch between context (more recent) and older mp code

I must admit that I installed the new cont-tmf.zip over the old one without uninstalling the old first. But there is no mp code that wasn't overwritten.

not needed, as long as you don't get duplicates

strange then, was a new metafun format generated?
