[NTG-context] proposed convention for variation switching [wasRE:inheriting ...

===== Original Message From "Adam Lindsay" =====

I don't have time to really delve into the implementation details, but it looks like the difference is that ConTeXt isn't so responsive with user- defined alternatives with more than two characters. Compare the stripped down version with your own. Your \scsb has been changed to \SB, effectively.

Hmm, I was a little worried at first about >2-char switches at first, till I noticed that type-siz.tex uses some four-letter switches as well, e.g. ============line-575============== \definebodyfont [12pt] [mm] [mrbf=xcmb12, exbf=cmex10 at 12pt, mibf=cmmib10 at 12pt, sybf=cmbsy10 at 12pt] ===================================== So I assumed that such a scheme would work. My suggestion: Either a) the \*a(b)(c) etc mechanism needs modification to accomodate >2-char switches, or b) an official 2-char switching convention for dealing with semibold and the standard five variants of small caps in ConTeXt is needed. Ideally users should not have to define switches for these standard variants anyway. Here is an idea (further discussion needed): a) Let's assume no change to the ConTeXt internals to accomodate >2-char switches. b) There are twelve basic style variants in a professional modern serif font (math, greek, etc excluded): six for lower case and six for small caps. On this basis, here is my suggestion for an official ConTeXt convention for professional fonts: %% lowercase % medium \tf % semibold \sb % bold \bf % italic \it % semibold italic \st % bold italic \bi %% small caps % medium \TF % semibold \SB % bold \BF % italic \IT % semibold italic \ST % bold italic \BI The small caps versions are identical to the lowercase versions, with the difference that the small caps versions use caps. This serves as a mnemonic device. We also need some long-winded control sequences: \definestyle [semiboldroman,semibold] [\sb][] \definestyle [semibolditalic] [\st][] \definestyle [smallcapssemibold,semiboldsmallcaps] [\SB][] \definestyle [smallcapsbold,boldsmallcaps] [\BF][] \definestyle [smallcapsitalic,italicsmallcaps] [\IT][] \definestyle [smallcapssemibolditalic,semibolditalicsmallcaps][\ST][] \definestyle [smallcapsbolditalic,bolditalicsmallcaps] [\BI][] An identical or similar analysis may work for sans-serif, but I have to check...
