gno.land/r/nym-moultest123/demo/render

Step 4 of the r/moul/demo walkthrough: Render, the read-only view a realm exposes to gnoweb.

1func Render(path string) string

Render receives whatever follows the : in the URL and routes on it. Three routes are wired here:

Render is a query, not a transaction: no gas, no signature, and it must be deterministic.

1gnokey query vm/qrender -data 'gno.land/r/nym-moultest123/demo/render:greetings/manfred' \
2  -remote https://rpc.gno.land:443

Caveat, kept on purpose. The index route still emits links to /r/moul_basics_004:, the path this code was written against in an older workshop. They do not resolve at this realm's current path. It is a good illustration of the trap: a hardcoded self-link becomes wrong the moment the realm moves, so build links from the request path (see p/moul/realmpath) instead.
