Querying 'if' block statements in Overpass API

[EsbernJakobsen]

Using Overpass Turbo you can add if block statements to query by conditions. For example, if I want all roads that include tunnels, I can query:
way["tunnel"="yes"]["highway"](if: length() > 80)(area); out;

Currently, I don't believe there is any way to do this using the overpassQueryBuilder.
If you add this 'if' block to the selector argument, the 'if' block becomes enveloped in [] in the query string:
way["tunnel"="yes"]["highway"][(if: length() > 80)](area.searchArea););
This causes an error.

Is there currently any functionality to support 'if' block conditions when querying the Overpass API?

Sadly, there has not been implemented such functionality. I would suggest to not use the overpassQueryBuilder in this (and similar cases) but write the query as a string. Sorry.

No worries, if I have time I might have a look at the code and see if I can implement something !
