Nested Macros

[abdulshafy]

Hello all,
What I need to do is to define some macro in a template in terms of another macro which is defined inside the hosts linked to that template.

Ex.

In template:
{$LANIF} ⇒ 10.{$BN}.1.1

In a host linked to the template:
{$BN} ⇒ 55

I'm not able to do that! and the only thing that works is to define macros to resolve to a static value.
Any help will be much appreciated.

Still looking for an answer!

This question has recently been brought up internally and we have decided that recursive user macros like the ones you mentioned will not be supported.

[abdulshafy]

Oh it would be very useful! as it would, dramatically, facilitate configuration!, is there any workaround?

[asaveljevs]

Unfortunately, there does not seem to be. One of the reasons why we have decided against is that recursive user macros might slow the frontend significantly.

A better trade-off would be limiting the depth of recursion levels, may be to 1, thus avoiding significant performance degradation.

But why?
Grafana supports nested macros. Why you decided to not support this? This just cuts down all the flexibility this functionality could provide.
