did you try the latin modern fonts? they have many composed characters as well as more/better accents

No, I've never tried them... Ok, I found them; where are the typescripts for them? http://dante.ctan.org/CTAN/fonts/ps-type1/lm/tex/ only has latex support files. Does lm support oldstyle numerals by default? Anyway, I have spent soo many hours tweaking cm for my projects I am a bit afraid to switch at the moment; have a huge project due next week... Is there anything quick and dirty I can do till I have time to experiment with lm?

Could not interest anyone in the \=i problem, I guess. Anyway, could someone tell me how ConTeXt defines \=i (so as to always get plain \=\i)? Best Idris On Mon, 24 May 2004 12:42:00 -0600, Idris Samawi Hamid wrote:

Very funky stuff, accents in ConTeXt. You'd have to dig up in enco-acc plus the other enco-* files.

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; =============imacron.tex================== \setupoutput[pdftex] \setupbodyfontenvironment[default][em=italic] \def\SHIFT#1{\dimen0=.00#1ex \multiply\dimen0 by\fontdimen1\font \kern-.0156\dimen0} % compensate for slant/italic in lower accents \def\USHIFT#1{\dimen0=.00#1ex \multiply\dimen0 by\fontdimen1\font \kern.0156\dimen0} % compensate for slant/italic in upper accents \def\IBAR% {\leavevmode\vbox{\offinterlineskip\lineskip0.295ex% %\ialign{##\cr\USHIFT{120}\hbox to .27777em% %% for width of i-box %{\leaders\hrule height .067354ex\hfill}% %\SHIFT{1}\cr\i\cr}}} \ialign{##\cr\USHIFT{120}\hfill\hbox to .21243em% %% for width of i-glyph base {\leaders\hrule height .067354ex\hfill}% \hfill\SHIFT{1}\cr\i\cr}}} \starttext \definecharacter imacron % {\buildtextaccent\textmacron \dotlessi} % original def from enco-def.tex \=i \=I {\em b\=in\=ary} f\=i\high{\txx c}\=i % {\bi b\=in\=ary} % need conditionals for bold and small caps \blank[big] \definecharacter imacron {\IBAR} % new imacron \=i \=I {\em b\=in\=ary} f\=i\high{\txx c}\=i % {\bi b\=in\=ary} \stoptext ================================================================== 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 soooo 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.

ah, we stand you sitting there crying over tex, can we?

Sometimes I want to curse TeX, believe me... Seriously though, I have a real phobia for all that low low-level stuff... 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

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 Am I missing something? Thnx 2 all Idris -- Professor Idris Samawi Hamid Department of Philosophy Colorado State University Fort Collins, CO 80523

Hans Hagen said this at Tue, 1 Jun 2004 21:04:49 +0200:

take a look at font-ini and search for the definition of \em; but since you suffered already a lot:

Hey Hans, I like this one a lot. It's more of what I imaged when you mentioned "fonts" and "parameters". (But I managed something interesting there... need to write it up.) I'd prefer (at least a variant) that does it based on fontstyle as well: \unprotect \definesystemvariable{sx} \def\definestylecollection {\dotripleargument\dodefinestylecollection} \def\dodefinestylecollection[#1][#2][#3][#4]% {\unexpanded\setvalue{#1}{\styleinstance[#1]}% \setvalue{\??sx#1:#2:#3}{#4}} \unexpanded\def\styleinstance[#1]% {\executeifdefined{\??sx#1:\fontstyle:\fontalternative}{\getvalue{\? ?sx#1:\fontstyle:\s!default}}} \protect \definestylecollection[caps][ss][default][\sc] \definestylecollection[caps][ss][bf][\bc] \definestylecollection[caps][ss][bi][\bc] \definestylecollection[caps][ss][bs][\bc]

let me know if this works ok, maybe i can add it to the kernel then

Works fine here. So. Now that we can parameterise font alternatives much more easily, can there be some sort of agreement on other, expanded names for font alternatives that go beyond the ones that cmr offers? I'm currently playing with these names (some grabbed from Hans's draft of Utopia support in type-siz).
