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).
