Specifying font style variant with \definefontfamily

Specifying font style variant with \definefontfamily

[Pavneet Arora]

I'm still a bit at a loss on how one goes about correctly specifying the 
variants in \definefontfamily using the default form given in the wiki.  
Usually adding "* Light", etc. is sufficient (see commented line using 
Junction font).

(As an aside, is it also possible to combine \sc\bf?  I haven't been 
able to figure that out).

My application is using the (free) Andada font family, and I need to 
point the smallcaps style to the correct font 
(https://www.fontsquirrel.com/fonts/andada).

In the following MWE I tried the following without success:

1.  [sc=* SC Regular]
2.  [sc=Andada SC Regular]
3.  [sc=* SC-Regular]
4.  [sc=Andada SC-Regular]

All give the following (or similar) error to stdout:

...ext/tex/texmf-context/tex/context/base/mkiv/font-sel.lua:121: attempt to index local 'file' (a nil value)
stack traceback:
  ...ext/tex/texmf-context/tex/context/base/mkiv/font-sel.lua:121: in function 'selectfont_savefile'
  ...ext/tex/texmf-context/tex/context/base/mkiv/font-sel.lua:151: in function <...ext/tex/texmf-context/tex/context/base/mkiv/font-sel.lua:142>
  ...ext/tex/texmf-context/tex/context/base/mkiv/font-sel.lua:526: in function 'registerfiles'
  ...ext/tex/texmf-context/tex/context/base/mkiv/font-sel.lua:567: in function 'action1'
  [string "local function scan1()..."]:55: in function <[string "local function scan1()..."]:42>

 1     \definefontfamily[mainface][rm][Latin Modern]
 2 >>  \definefontfamily[mainface][rm][Andada][sc=Andada SC Regular]


I end up finally settling on the form using the explicit file: 
[sc=file:AndadaSC-Regular.otf], which does work.

But I really would like to understand how the first form as given in the 
wiki should be used properly?  What patterns should I be looking for?

An output of 'strings' on the font .otf file yields:

    "... with Reserved Font Name 'Andada'Andada SCRegular"
    "AndadaSC-Regular"

advTHANKSance.

There was a bug in the code but I fixed it.
