Hi Diego, I think the following butlast/last trick was given by Jed Carty a few hours ago. It looks quite verbose because the outer list is essentially duplicated, but I think it handles your three issues.
<$list filter="[is[current]fields[]regexp[-url]butlast[]]" variable="fieldname"> <$list filter="[<fieldname>splitbefore[-]removesuffix[-]]" variable="fieldprint"> <$text text=<<fieldprint>>/> : <$link to=<<fieldprint>>><$view field=<<fieldname>>/></$link>, </$list> </$list> <$list filter="[is[current]fields[]regexp[-url]last[]]" variable="fieldname"> <$list filter="[<fieldname>splitbefore[-]removesuffix[-]]" variable="fieldprint"> <$text text=<<fieldprint>>/> : <$link to=<<fieldprint>>><$view field=<<fieldname>>/></$link>. </$list> </$list> Best, X. -- Xavier Cazin On Fri, Dec 1, 2017 at 9:29 PM, Diego Mesa <diego...@gmail.com> wrote: > After reading/searching/experimenting I got: > > <$list filter="[is[current]fields[]regexp[-url]]" variable="fieldname"> > <$list filter="[<fieldname>split:before[-]]" variable="fieldprint"> > <$text text=<<fieldprint>>/>: <$view field=<<fieldname>> /> <br/> > </$list> > </$list> > > There is still some confusion about the use of << vs < when referencing > variables, and why I don't have to wrap <fieldname> with [<fieldname>] > before giving it to split. > > Remaining issues: > > - actually making those render as URLs > - If I replace the <br/> with a comma to get them all on one line, I'm > left with a trailing comma > - If I instead try to generate external links as: [[<$text > text=<<fieldprint>>/>|<$view field=<<fieldname>> />]] it doesn't work. > > There is still some residual confusion about using nested lists as nested > for loop analogs, and how to actually use the variables in the "loops". > > > On Friday, December 1, 2017 at 2:04:41 PM UTC-6, Diego Mesa wrote: >> >> Hey all, >> >> I am trying to display a header for all posts tagged PoI that does, among >> other things, display any urls I've placed in its fields.
