[Qgis-developer] Multiple replacements in a string

[Neumann, Andreas]

Hi all, Hi Nyall, 

Came across https://twitter.com/northroadgeo/status/770490090724491265
demoing the replacements of multiple values at once through a nice GUI
where you can define a replacement map.  

I wonder if we couldn't have a more powerful replacement function like
this in the QGIS expressions as well, something like: 

replace(string, replacement_map) where replacement_map would be a
dictionary such as defined in the above tweet, e.g. 

replace(streetname,{'Road'->'Rd','Lane'->'Ln','Highway'->'Hwy'}) 

That way we could use it everywhere we want (not just in the labeling
part) and it would be much easier to write than having to nest multiple
replace() statements. 

Would this be achievable for QGIS 3.0? 

Thanks for your feedback, 

Andreas
