fontfeatures

[Wolfgang Schuster]

Hi Hans,

what happened with the option to set font features with more  
memorizable names
you mentioned in http://www.ntg.nl/pipermail/ntg-context/2007/028330.html

It would be nice to write \definefontfeature[mine][smallcaps=yes]  
instead
of \definefontfeature[mine][smcp=yes] where you have to know the four  
letter
code for the feature.

Wolfgang

as mapping is already kin dof present, if you add

for k, v in pairs(to_features) do
     to_features[gsub(k," ","")] = v
     k = lower(k)
     to_features[k] = v
     to_features[gsub(k," ","")] = v
end

to font-ott.lua then you can say:

\starttext

% \definefontfeature[smallcaps][smcp=yes,script=latn]
% \definefontfeature[smallcaps][SmallCapitals=yes,script=latn]
% \definefontfeature[smallcaps][Small Capitals=yes,script=latn]
% \definefontfeature[smallcaps][small capitals=yes,script=latn]
\definefontfeature[smallcaps][smallcapitals=yes,script=latn]

\definedfont[cambria*smallcaps] test

\stoptext

of course you need to memorize the huge feature name table

if needed we can add some extra common entries, like smallcaps and 
oldstyle but someone needs to collect them

We should restrict this to one alternative (besides smcp=yes) and
the last variant seems to me like the context way (lowercase keys
without spaces in it).

Why, you can make a table where there normal feature name (Uppercase  
with spaces)
is listed together with the normalized form (lowercase, no spaces) and  
the four
letter form.

Sure, the wiki is a good place for this.

well, your asked for smallcaps and got smallcapitals and remembering the 
  (sometimes long verbose names is no fun either)

we might even want to strip everything except a-z0-9

Terminal Forms #2
Above-Base Substitutions

I know, I did this already in the last version of my simplefonts  
module where I played
with this to enable certain features which are not part of the  
standard fontfeatures.

Example: \setmainfont[Delicious][oldstylefigures=yes]

What have to be removed are: spaces, number sign, hyphen, slash

better is to keep, as in:

for k, v in pairs(to_features) do
     local stripped = gsub(k,"%-"," ")
     to_features[stripped] = v
     local stripped = gsub(k,"[^a-zA-Z0-9]","")
     to_features[stripped] = v
end
for k, v in pairs(to_features) do
     to_features[lower(k)] = v
end

(btw, i uploaded a beta with some of last weeks fixes)
