#974 has been merged. Is this PR still relevant? |
|
it can be but I know some other contributors opened other versions of that |
|
I will revisit |

bool is not needed, != nil is enough.

add a MustGet(pkgPath string) grc20.IGRC20 that panics if not found.

this check is unnecessary, protected by Register.

you can now use uassert if you want more concise tests :)

To support registering several tokens from the same contract.

forked your PR here -> #2516 |

Closing in favor of #2516 |
This is a contract that allows to get a GRC20 user interface from a realm pkg path
It's an example of the registry pattern that allows to dynamically access realms interfaces
Caveat: this depends on #974 being fixed, if this would be merged now, it would steal ownership of the foo20 token object and make it unusable
