I didn't check one by one, but calling directly the ping template with all the parameters will work while calling ping with a template which transclusion provide the same string, so "Amqui|Ariel1024|…" won't work. So, maybe it's the vertical bar "|" which is not interpreted as a parameter separator in this case and the whole string is passed as a single parameter.

Or, maybe the last user name came with end of line, as part of template transclusion, and this will kill the mw.title.new/1 function. Igal (User:IKhitron) 2017-09-24 18:41 GMT+03:00 mathieu stumpf guntz <psychoslave(a)culture-libre.org>rg>: I'm trying to solve the problem exposed here:https://meta.wikimedia.org/wiki/User_talk:Psychoslave#Templa te:Participants (in French) In a nutshell, the goal is to be able to ping a group of user on meta. so ideally, you just type something like {{ping|my_group}} But as ping and the underlying "Module:Reply_to" are expecting one user per argument my current idea is to make something like {{ping|{{:/some_group/members} }}} so instead of {{ping|Amqui|Ariel1024|Aryamanarora|Benoît_Prieur|Daniel_ Kinzler_(WMDE)|Delarouvraie|Epantaleo|Ernest-Mtl| GastelEtzwane|JackPotte|Jberkel|Jitrixis|Kimdime|LA2|LaMèreV eille|Lydia_Pintscher_(WMDE)|Lyokoï|M0tty|Malaysiaboy| Marcmiquel|Micru|Nattes_à_chat|Nemo_bis|Noé|Otourly| Pamputt|psychoslave|Rich_Farmbrough|Rodelar|Satdeep_ Gill|Sebleouf|Shavtay|Stalinjeet|S_The_Singer|TAKASUGI_ Shinji|TaronjaSatsuma|Thibaut120094|Thiemo_Mättig_(WMDE)|tpt|Trizek_(WMF)| VIGNERON|Vive_la_Rosière|Xabier_Cañas|Xenophôn}} I can just write {{ping|{{:Wiktionary/Tremendous Wiktionary User Group/affiliates}}}} for example but even if I put verbatim in a template: Amqui|Ariel1024|Aryamanarora|Benoît_Prieur|Daniel_Kinzler_(W MDE)|Delarouvraie|Epantaleo|Ernest-Mtl|GastelEtzwane|JackPot te|Jberkel|Jitrixis|Kimdime| LA2|LaMèreVeille|Lydia_ Pintscher_(WMDE)|Lyokoï|M0tty|Malaysiaboy|Marcmiquel|Micru| Nattes_à_chat|Nemo_bis|Noé|Otourly|Pamputt|psychoslave| Rich_Farmbrough|Rodelar|Satdeep_Gill|Sebleouf|Shavtay| Stalinjeet|S_The_Singer|TAKASUGI_Shinji|TaronjaSatsuma |Thibaut120094|Thiemo_Mättig_(WMDE)|tpt|Trizek_(WMF)| VIGNERON|Vive_la_Rosière|Xabier_Cañas|Xenophôn in the page and call ping with this template as argumement, it will end up with a "Error in Template:Reply to: Input contains forbidden characters." This message is generated by the module Reply_to but I can't change it since it's protected. So I'm looking for a way to bypass whatever generate this error, or more broadly any idea to resolve the exposed problem. _______________________________________________ Wikitech-l mailing listWikitech-l@lists.wikimedia.orghttps://lists.wikimedia.org/mailman/listinfo/wikitech-l _______________________________________________ Wikitech-l mailing listWikitech-l@lists.wikimedia.orghttps://lists.wikimedia.org/mailman/listinfo/wikitech-l

Why not just make a template containing <includeonly>{{ping|first user|second user|third user|...}}</includeonly> Your issue is almost certainly that the pipes aren't being tokenized as argument separators when they come from a transcluded template. (Its the same reason that {{!}} works in tables, except in reverse). Alternatively, {{ping|{{subst::Wiktionary/Tremendous Wiktionary User Group/affiliates}}}} would probably work.

Le 24/09/2017 à 19:31, bawolff a écrit : I encounter a similar problem in an other template I'm trying to write. Indeed, `subst` works as expected, but I would like to keep the call as is. So that when saving, the list won't be expanded, but will stay dynamic. So using the same example, something like {{ping|{{param::Wiktionary/Tremendous Wiktionary User Group/affiliates}}}} Is there already a way to do that.

The other option I see is that the called template or module called should directly return the whole call. Actually, with a frame:expandTemplate or frame:preprocess it does work for the case I was asking this question.
