Hi all,
experimenting with context.labeltext...
My question is how can I tweak the context.labeltext(text) command at the lua-side to make ConTeXt to typeset the labeltext starting with an uppercase letter? e.g. if "text" contains "january" to display "January"?
KR
Willi

You can access constants and variables with “interfaces.constants” and “interfaces.variables”:
\starttext
\startluacode
context.labeltext("%s",interfaces.variables.january)
\stopluacode
\stoptext

Hello Wolfgang,
thanks for your reply.
I see that I was not quite clear with my explanation.
The situation is the following:
in a function which runs over the months of the year at a certain moment I need to insert at the ConTeXt side the monthname. However the monthname returned by the following statement is all lowercase, which is ok for the translation of the labeltext. In the document however I need the labeltext in with a starting uppercase letter. The question is therefor how to achieve this uppercase first letter
\startluacode
function monthtable(month)
local direct = true
local nofdays = converters.nofdays(os.date("%Y"),month,direct)
direct = false
local d = os.date("%B",os.time({year=os.date("%Y"),month= month,day=1}))
context.bTABLE({setups="table:month"})
context.bTR({align="middle"})
context.bTD()
context.labeltext(d)
-- context.labeltext("%s",interfaces.variables.january)
context.eTD()
context.eTR()
for i = 1, 31 do
context.bTR()
context.bTD()
if i < nofdays +1 then
context(i)
else
context()
end
context.eTD()
context.eTR()
end
context.eTABLE()
end
\stopluacode
\def\maandtabel#1{\ctxlua{monthtable(#1)}}
\starttext
\maandtabel{2)
\stoptext
Kind regards
Willi

???
The first letter in the month name you get from Lua is uppercase as you can see in the output from your example.
To make the first letter uppercase at the TeX side you can use “context.Word(...)”.

And if text is foo you want Foo ?
In char-ini.lua, among others, there is
function characters.upper(str)
local new, n = { }, 0
for u in utfvalues(str) do
n = n + 1
new[n] = ucchars[u]
end
return concat(new)
end
The idea is to take the first character from characters.upper(str),
and all but not first from str
and then join them using concat.

Hi Luigi,
hm, did not know this one. Still I can not see that this is going to fit in my situation. I refer to may other mail I sent a minute ago. - The thing is, that the document I am building should be multilingual and therefore I need at the lua-end the lowercase text which should be made first-letter-uppercase at the moment it is typeset.
Thanks
Willi

In the first email you talked about a generic label. Uppercase /lower
case are unicode sensitive; as Wolfgang already wrote
string.lower(..) and string.upper(..) can help , but they depend on
the current locale which can confuse things.
So it's better to look at char-ini.lua .

unicode.utf8.lower()/upper() are a better choice for non-ASCII text.
(I still believe the default string manipulation functions should be
Unicode aware by default, and the 8-bit ones should be an alternative,
not the other way around).

ConTeXt provides also characters.upper()/lower().

you can just rename/remap them if needed; swapping stock lua and unicode
functions would render regular lua manuals/tutorials useless and also
make lua 8-bit dirty
(local lower = utf.lower at the top of a file is enough to get what you
want)
