The following transformation steps should be implemented as soon as possible, as they would be particularly useful to start experimenting with the initial releases of Web2Cit-Core and Web2Cit-Server:
It is worth noting that in the meantime, as a workaround, one may use a Split transformation followed by a Join transformation, as suggested by @Kerry_Raymond. However, Split transformation does not support regular expressions.
Regarding Replace transformation, how do we distinguish pattern and replacement parameters in the config value while T305903 is not supported?
We may use a syntax similar to sed substitution: /pattern/replacement/flags. We should note syntax is sed-like, but it is NOT sed.
This would be used as String.prototype.replace(/pattern/flags, replacement), with /pattern/flags as regular expression and replacement as string.
Special replacement patterns would be supported as indicated in https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/replace#specifying_a_string_as_the_replacement.
A simpler pattern/replacement syntax may be supported for simpler replacements, with both pattern and replacement interpreted as strings.
Special replacement patterns would be supported
It should also be noted that, as a result, literal $ characters should be escaped in replacement parameter as $$.
Replace transformation inplemented in Web2Cit-Core with 230f83c6.
Pending documentation update in https://meta.wikimedia.org/wiki/Web2Cit/Docs/Templates#Replace_transformation_(proposed).
Pending w2c-core library update in Web2Cit-Server and deploy.
