Dear list
I need to typeset a book for kids wich contains texts where each letter is assigned a fixed color, for example:
A - - > red; B - - > blue; ... Z - - > green.
What would be the best way to do this? TIA. There's more ways to do this but here is one:
(1) make a file: colorfont.lfg: return { name = "coloralphabet", colorschemes = { default = { [1] = { "a", "e" }, [2] = { "i", "o", "u" }, }, whatever = { [1] = { "65:90" }, [2] = { }, [3] = { }, [4] = { "97:122" }, } } } There is some more possible but this wil do ... (2) You define a font with these goodies attached: \setupbodyfont[plex,10pt] \definefontfeature [MyFeaturesA] [default] [goodies={colorfont},colorscheme=default,liga=no] \definefontfeature [MyFeaturesB] [default] [goodies={colorfont},colorscheme=whatever,liga=no] \definefont[MyFontA][Serif*MyFeaturesA] \definefont[MyFontB][Serif*MyFeaturesB] (3) and use it this way: \starttext \setfontcolorscheme[1] {\MyFontA \samplefile{tufte}}\par \setfontcolorscheme[2] {\MyFontA \samplefile{tufte}}\par \setfontcolorscheme[3] {\MyFontA \samplefile{tufte}}\par \page \setfontcolorscheme[1] {\MyFontB \samplefile{tufte}}\par \setfontcolorscheme[2] {\MyFontB \samplefile{tufte}}\par \setfontcolorscheme[3] {\MyFontB \samplefile{tufte}}\par \stoptext Now, this is pretty (more than a decade) old functionality from early days of mkiv/luatex when it was used for some tracing (by Idris) and it still works (surprise). Today I would definitely use more recent trickery. If there is real demand for this I can have a look at it, after all it's "kind of fun" (as is most of font stuff).
