\externalfigure doesn't find mps file in subdirectory
\externalfigure won't find a metapost eps file in a subdirectory, if the mps has the numerical (.1) extension. Here's a minimal example (test.tex): \setupexternalfigures[directory={fig}] \starttext \externalfigure[simple.1] \stoptext where fig/simple.1 is from a simple .mp file that fills a 1-cm box (see below). The resulting test.pdf shows the gray box name : simple.1 file : simple.1 state: unknown Only this combination of circumstances triggers the problem. Giving the full path ("\externalfigure[fig/simple.1]") works fine, as does renaming the file to simple.mps (within the fig/ directory), as does using instead simple-1.pdf (made with mptopdf). Thus, I have several workarounds, but it might be useful to figure out what is not working. I've noticed this problem on and off for a while now, but only now made a minimal example. (Is the path-searching code trying to append extensions and directory prefixes at the same time, and thus not finding the file?) This is with MkIV 2013.05.28 from vanilla TL2013. For completeness, here's simple.1, although any file will show the problem equally well: %!PS %%BoundingBox: 0 0 29 29 %%HiResBoundingBox: 0 0 28.34645 28.34645 %%Creator: MetaPost 1.803 %%CreationDate: 2013.08.04:0841 %%Pages: 1 %%BeginProlog %%EndProlog %%Page: 1 1 0 0 0 setrgbcolor newpath 0 0 moveto 28.34645 0 lineto 28.34645 28.34645 lineto 0 28.34645 lineto closepath fill showpage %%EOF -Sanjoy

Here's the debugging info after enabling the graphics.locating tracker (which I learned about at the very useful page http://wiki.contextgarden.net/Command/externalfigure): graphics > inclusion > forcing format '1' graphics > inclusion > 'simple.1' cannot be resolved graphics > inclusion > './simple.1' cannot be resolved graphics > inclusion > '../simple.1' cannot be resolved graphics > inclusion > '../../simple.1' cannot be resolved graphics > inclusion > 'fig/simple.1' resolved to 'fig/simple.1' graphics > inclusion > format '1' is not supported -Sanjoy
Hi Sanjoy, Sorry for the late reply; I had to dig around in grph-inc.lua, and I'm a bit rusty at source-diving. Yep, that’s a problem all right. A bug, even: when you put `simple.1` in the same directory as the `.tex` file, it is correctly identified as MetaPost; when you put the exact same file in a subdirectory like `./fig`, you get the problem you describe. No clue why. Until Hans fixes this, you can force ConTeXt to treat a file as MetaPost, JPEG, etc. by passing the `method=` paramater to `\externalfigure`. For MetaPost, write `method=mps`; I don’t know why the MetaPost code is not `mp`. (Perhaps that could be made a synonym?) Complete example below. I hope this workaround helps? Good luck with your work! Cheers, Sietse % test.tex \setupexternalfigures[directory={fig}] \enabletrackers[graphics.locating] \starttext \externalfigure[simple.1][width=10cm, method=mps] \stoptext % fig/simple.1 %!PS %%BoundingBox: 0 0 29 29 %%HiResBoundingBox: 0 0 28.34645 28.34645 %%Creator: MetaPost 1.803 %%CreationDate: 2013.08.04:0841 %%Pages: 1 %%BeginProlog %%EndProlog %%Page: 1 1 0 0 0 setrgbcolor newpath 0 0 moveto 28.34645 0 lineto 28.34645 28.34645 lineto 0 28.34645 lineto closepath fill showpage %%EOF

you can test with this (line 767 in grph-inc): askedformat = format -- new per 2013-08-05 elseif trace_figures then report_inclusion("unknown format %a",askedformat) end
Cheers, Sietse

That fixes the problem, hooray! \o/ Cheers, Sietse
Hans, Sietse, Thank you very much: method=mps works, as does Hans's lua code. Best, -Sanjoy
