Did u have a chance 2 look at my general solution 4 medium fonts? I would
like to generalize it to bold and small caps but I don't understand how to
set up a conditionals macro that expands in accordance with the
surrounding font. I need sthing like
\ifboldtrue
\IBARA % parameterized for bold fonts
\else
\ifsctrue
\IBARB % parameterized for sc fonts
\else
\IBAR % parameterized for medium fonts
\fi\fi
take a look at font-ini and search for the definition of \em; but since you
suffered already a lot:
\unprotect
\definesystemvariable{sx}
\def\definestylecollection
{\dotripleargument\dodefinestylecollection}
\def\dodefinestylecollection[#1][#2][#3]%
{\unexpanded\setvalue{#1}{\styleinstance[#1]}%
\setvalue{\??sx#1:#2}{#3}}
\unexpanded\def\styleinstance[#1]%
{\executeifdefined{\??sx#1:\fontalternative}{\getvalue{\??sx#1:\s!default}}}
\protect
\definestylecollection[mine][default][sorry]
\definestylecollection[mine][bf][\sl]
\definestylecollection[mine][sl][\tt]
{\bf test \mine test \sl test \mine test \bs oeps \mine oeps}
let me know if this works ok, maybe i can add it to the kernel then

in addition to gb's solution:
Very funky stuff, accents in ConTeXt. You'd have to dig up in
enco-acc plus the other enco-* files.
\=i becomes \imacron
which by default (enco-def) becomes
\definecharacter imacron {\buildtextaccent\textmacron \dotlessi}
which you can study in enco-ini :)
you can play with:
\starttext
% \startencoding[...]
\defineaccent = {idris} {\idris}
\definecharacter idris {sirdi}
% \stopencoding
he \={idris}!
\stoptext

I don't get it; when I run this as given I don't get any accents; I just
get
he sirdi! Am I missing something?
Thnx 2 all

I actually found this last night, digging in the ConTeXt code. U're right:
VERY funky stuff;-)
But it's really nice, since, thnx 2 the way Hans has abstracted things,
the solution for \=i has no effect on \=I or anything else:-)
Anyway, I now have a working proper accent now for \tf and \it;

A word on the parameters: I ran tftopl on cmr12.tfm, made a note of the
QUAD and X-HEIGHT values, as well as the width of the i-box. I opened
\cmr12.pfb in FontLab and made some measurements of the i-glyph and the
macron bar; dividing a given width by the QUAD-value gives the rlative em
values used above (similarly for the lineskip calculation, dividing
heights by X-HEIGHT).
The definition of \IBAR has two possibilities: macron is width of the
i-box, or it's the width of the base of the i-glyph. Upon experimentation,
I found the latter width more aesthetically pleasing, but I have kept the
other as an option (commented). In fact, making the macron the width of
the i-box may make better sense for \sc.
PROBLEM: Now I need to learn more about \TeX conditionals, because this
solution does not work for \bf, \bi, and the like. The height of the
imacron bar needs to be greater for bold fonts. How can I make a set of
three conditionals such that the definition of \IBAR has a different
expansion for
\tf, \it, \sl etc.
\bf, \bi, \bs etc.
\sc
??? That is, when \bf is on, the definition of \IBAR should expand a
conditional that is based on the bold-dependent parameters.
Anyway, for \tf and \it this looks s much better than the plain.tex
imacron; Please try it out! And I'm open to suggestions on tweaking the
parameters to make this look better.
Best
Idris
