Hi all,
I can't find a way to insert code into the last argument of
\DeclareFontShape in a .fd-file directly from a fontinst driver file.
From the manuals (fontinst.pdf& fntguide.pdf):
\installfont {<font-name>} {<metrics-list>} {<etx-list>}
{<encoding>} {<family>} {<series>} {<shape>}
{<size>}
\DeclareFontShape {<encoding>} {<family>} {<series>} {<shape>}
{<loading-info>} {<loading-settings>}
Tokens inside \installfont...{<size>} will end up in
\DeclareFontShape...{<loading-info>}. I want to have one token in
{<loading-settings>}, preferably without using `sed'. Any hint, or am
I missing the obvious?
No, you're not missing anything. Fontinst has an interface for putting
custom loading-settings in the \DeclareFontFamily declaration (last argument
of \installfamily), but not for putting such in individual \DeclareFontShape
declarations. Indeed, \fd_shape (which is responsible for generating the
\DeclareFontShape declarations) has this sixth argument hardwired to being
empty.
I can see two reasons for this:
1. Nobody has (yet) reported an actual use-case for this feature, instead
being content with using the \DeclareFontFamily loading settings (and even
that is rare).
2. The per-shape storage of FD data in fontinst uses full expansion, so
passing arbitrary code that way is not entirely straightforward (but
certainly doable).
It's not too hard to implement---easiest would be to have a variant macro
\fd_shape_with_loadspec to be used instead of \fd_shape---but I don't see an
obvious user level interface for specifying the extra information
(\installfont already has a ton of arguments).
Do you have a use-case in mind, or was it just a matter of exploring all
options? In the former case, I would be interested to hear about it.
