LuaTeX-Plain and OTF/TTF Fonts

Dear Group,  

Thank you for your time. I'm starting out with TeX/ConTeXt, but
want to arrive via LuaTeX (`luatex-plain.tex/fmt`). Managed to
build, move and use `luatex-plain`. Have the same problem under
MacOSX & Win7 (here is the Win-specific decription -- `%CTX%` is
my ConTeXt root):

Placed some fonts under `%CTX%\tex\texmf-fonts\otf\minion\` &
`%CTX%\tex\texmf-fonts\otf\myriad`. Executed, the following
commands, recognising there might be redundancy, but not sure):

    mtxrun --script fonts --update --force
    mtxrun --script fonts --update --simple
    mtxrun --script fonts --update
    mtxrun --script fonts --list --pattern=minion

Result:

    minionpro             minionprobold      MinionPro-Bold.otf
    minionprobold         minionprobold      MinionPro-Bold.otf
    minionproboldit       minionproboldit    MinionPro-BoldIt.otf
    minionprobolditalic   minionproboldit    MinionPro-BoldIt.otf
    minionproit           minionproit        MinionPro-It.otf
    minionproitalic       minionproit        MinionPro-It.otf
    minionpronormal       minionproit        MinionPro-It.otf
    minionproregular      minionproregular   MinionPro-Regular.otf


`hello.tex` - luatex-plain test file:

    %[luatex-plain] Hello
    %
    font\T =minionproregular at 12pt\T
    Hello world.
    \bye

Executed:

    luatex-plain hello.tex

Result:

    fonts : font with asked name 'minionproregular'  
      is not found using lookup 'name'
    fonts : unknown font 'minionproregular', loading aborted
    ! Font \ch=minionproregular at 12pt not loadable:  
      metric data not found or bad.

Looked in `%CTX%\tex\texmf-cache\luatex-cache\generic\fonts\data`
at the file `luatex-font-names.lua`. The fonts were listed. Then
deleted the `luatex-font-names.luc` file, added the full paths
to the fonts in front of all the file names in the `.lua` file.

Running `luatex-plain hello.tex` again, works now as expected (it
seems to recreate the `luatex-font-names.luc` automatically).

Setting `OSFONTDIR` before font update and/or before running
`luatex-plain`, have no observable effect.

So, I do have a manual fix/solution. But is there an easier way?

Thanks in advance,

I assume you made a plain format with:

   mtxrun --script plain --make

Then, does this work:

   mtxrun --script plain luatex-test

okay?

Hi Hans,

No, I made it with `luatex --ini luatex-plain.fmt` and copied
the resulting `.fmt` file. But, I executed the first command
just now, just to be sure, and then ran the next command:
`mtxrun --script plain luatex-test`. Result:

\write18 enabled.
...
tex/texmf-cache/luatex-cache/generic/fonts/data/luatex-fonts-names.luc)(load 
luc
: 
c:/ctx/tex/texmf-cache/luatex-cache/generic/fonts/otf/lmroman10-bold.luc)<unkn
own font in database, run: mtxrun --script fonts --reload --simple>
! LuaTeX error 
...ntext/tex/generic/context/luatex/luatex-fonts-merged.lua:6213:
 attempt to index field 'known' (a nil value).
<to be read again>
\par
l.33

?R<enter>

After `R`, it did produced `luatex-test.pdf`. Not sure if it
looks the way it should ... couple of overfull boxes, narrow
third page.

Either way, I updated the fonts again as above, checked that
it recreated the `luatex-fonts-names.lua` file like before.
If I delete the old `luatex-fonts-names.luc`, the next run of
`luatex-plain hello.tex` produces the same result. Added the
paths to the fonts in `luatex-fonts-names.lua` (minion &
myriad), ran `luatex-plain hello.tex` again ... and all is fine.

Further experimentation: Copied the "Source Sans Pro" fonts to
a subdirectory alongside the `minion` and `myriad` directories,
(`%CTX%\tex\texmf-fonts\otf\sourcesans`), and again updated the
fonts database(s). Upon inspection of `luatex-fonts-names.lua`,
the Source Sans fonts and files are listed, but they *did* have
the path prefixed to the font file names, and consequently, I
could use them without modifying `luatex-fonts-names.lua`.

Thank you for your reply. I'm convinced this is no bug, just my
inexperience at play. This is not a crippling problem. I can
tackle The TeXbook now.

Regards,
Aíre Funvake.
