G’Day,
Having a first go at converting TEI XML to ConTeXt.
Steep learning curve, but easier (for me) than XSLT, and first results were
amazing. Using http://www.pragma-ade.com/general/manuals/xml-mkiv.pdf as a
guide.
Currently stuck on converting an ISO format date (eg. 1908-01-10) into
something more readable (eg. 10 January 1908) in the output. I presume I
should create a function (?luacode) that can take any ISO value and output the
readable form. The following works but seems to me inefficient.
Grateful for any pointers.

Here is my MWE:
\startbuffer[demo]
<TEI>
<text>
<body>
<div type="letter">
<opener>
<date when-iso="1908-01-10" type="divDate">10.I.08</date>
</opener>
<closer>
<date when-iso="1908-03-19" type="secondDate">19 Mar '08</date>
</closer>
</div>
</body>
</text>
</TEI>
\stopbuffer
\startxmlsetups xml:initialize
\xmlsetsetup{#1}{date}{xml:date}
\stopxmlsetups
\xmlregistersetup{xml:initialize}
\startxmlsetups xml:date
\xmldoifelse {#1}{.[@type='divDate']} {
\def\docdate{\ctxlua{
local tyear = string.sub('\xmlatt{#1}{when-iso}',1,4)
local tmonth = string.sub('\xmlatt{#1}{when-iso}',6,7)
local tday = string.sub('\xmlatt{#1}{when-iso}',9,10)
context.date{d = tday, m = tmonth, y = tyear}
}}
\docdate[day,month,year] = Document Date \par
} {
\def\docdate{\ctxlua{
local tyear = string.sub('\xmlatt{#1}{when-iso}',1,4)
local tmonth = string.sub('\xmlatt{#1}{when-iso}',6,7)
local tday = string.sub('\xmlatt{#1}{when-iso}',9,10)
context.date{d = tday, m = tmonth, y = tyear}
}}
\docdate[day,month,year] = Event Date\par
}
\stopxmlsetups
\starttext
\xmlprocessbuffer{main}{demo}{}
\stoptext
Can be wikified ...
\startluacode
function xml.finalizers.tex.MyDate(e,what,how)
local t = string.split(e[1].at[what],"-")
context.date(
{ y = t[1], m = t[2], d = t[3] },
{ how }
)
end
\stopluacode
\startxmlsetups xml:date
\xmldoifelse {#1}{.[@type='divDate']} {
\xmlfilter{#1}{./MyDate("when-iso","day,month,year")}\
Document Date \par
} {
\xmlfilter{#1}{./MyDate("when-iso","day,month,year")}\
Event Date\par
}
\stopxmlsetups
I couldn’t get this to work.
Had to change it to:
\startluacode
function xml.finalizers.tex.MyDate(e,what,how)
local ee = e[1].at[what]
local t = (string.split(ee,"-"))
context.date(
{ y = t[1], m = t[2], d = t[3] },
{ how }
)
end
\stopluacode
You mean the () around the split? weird. Anyway, there's also a time
splitter (dedicated to Alan who needed one):
print(os.time(utilities.parsers.totime("2019-03-05 12:12:12")))
print(os.time(utilities.parsers.totime("2019/03/05 12:12:12")))
print(os.time(utilities.parsers.totime("05-03-2019 12:12:12")))
print(os.time(utilities.parsers.totime("05/03/2019 12:12:12")))
inspect(utilities.parsers.totime("2019-03-05 12:12:12"))
inspect(utilities.parsers.totime("2019/03/05 12:12:12"))
inspect(utilities.parsers.totime("05-03-2019 12:12:12"))
inspect(utilities.parsers.totime("05/03/2019 12:12:12"))
