But, it’d still love to hear whether there is a solution on the tex side. \processtokens {[before]} {[between]} {[after]} {[space]} {{one}{two}{three}}

\def\whatever{a,b,c,d}

\getcommacommandsize[\whatever] \scratchcounterone \zerocount \scratchcountertwo \commalistsize

\processcommacommand[\whatever] {\advance\scratchcounterone\plusone \ifnum\scratchcounterone=\scratchcountertwo \space and\space \orelse\ifnum\scratchcounterone>\plusone ,\space \fi \commalistelement}

Thanks.

but ... there's also:

\startlines \commalistsentence[aap,noot,mies] \commalistsentence[aap,noot] \commalistsentence[aap] \commalistsentence[a,b,c] \commalistsentence[a,b,c][{ \& },{ and }] \commalistsentence[a,b,c][+,-] \stoplines

which uses presets like

\setuplabeltext [nl] [and-1={{, }}, and-2={{ en }}] % 1, 2 en 3 \setuplabeltext [en] [and-1={{, }}, and-2={{, }}] % 1, 2, 3 \setuplabeltext [de] [and-1={{, }}, and-2={{ und }}] % 1, 2 und 3 \setuplabeltext [hr] [and-1={{, }}, and-2={{ i }}] % 1, 2 i 3

maybe wikify

I've just checked, \commalistsentence is already on the wiki, but you have to know it exists. (I'll check whether I can link to that page from somewhere.) But there's no (high-level) way to apply certain commands to this list elements, right? Background: My real use case is a bit more complex. I use comma separated lists to store author lists, but the authors themselves are saved in structured variables. So, I'll need to reassemble the different name parts first. So, nothing like \commalistprocessandmakesentence[a,b,c]\commandforfirst\commandforinbetween\commandforlast Probably to specific, right? %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% \startbuffer[test] <?xml version='1.0' standalone='yes?> <document> <title>This is the title</title> <author> <family-name>Doe</family-name> <given-name>John</given-name> </author> <author> <family-name>Smith</family-name> <given-name>Jane</given-name> </author> <p>This is a first sentence</p> </document> \stopbuffer \startxmlsetups xml:setup \xmlsetsetup{\xmldocument}{*}{-} \xmlsetsetup{\xmldocument}{document|p}{xml:*} \stopxmlsetups \xmlregistersetup{xml:setup} \startxmlsetups xml:document \xmlfilter{#1}{/title/command(xml:title)} \xmlfilter{#1}{/author/command(xml:author)} \startdocument \xmlflush{#1} \stopdocument \stopxmlsetups \startxmlsetups xml:title \setupdocument[title={\xmlflush{#1}},author={\AuthorList}] \stopxmlsetups \startxmlsetups xml:author:family-name \xmlflush{#1} \stopxmlsetups \startxmlsetups xml:author:given-name \xmlflush{#1} \stopxmlsetups \startxmlsetups xml:author \defineauthor[\xmlfilter{#1}{/family-name/command(xml:author:family-name)}\xmlfilter{#1}{/given-name/command(xml:author:given-name)}][family-name={\xmlfilter{#1}{/family-name/command(xml:author:family-name)}},given-name={\xmlfilter{#1}{/given-name/command(xml:author:given-name)}}] \addtocommalist {\xmlfilter{#1}{/family-name/command(xml:author:family-name)}\xmlfilter{#1}{/given-name/command(xml:author:given-name)}} \AuthorList \stopxmlsetups \startxmlsetups xml:p \xmlflush{#1}\par \stopxmlsetups \definenamespace [documentauthor] % name of internal varialbles [type=module, name=author, command=yes, % Create \defineauthor style=yes, % Create \useauthorstyleandcolor setup=list, % Create \setupauthor parent=documentauthor, ] \def\AuthorList{} \define[1]\useauthor {\edef\currentauthor{#1}% {\authorparameter{given-name} \space \authorparameter{family-name}}} \startsetups document:start \documentvariable{title}\endgraf \blank[medium] \processcommacommand[\documentvariable{author}]\useauthor \endgraf \stopsetups \xmlprocessbuffer{main}{test}{}
