How to compile DeSmuME on Debian or Ubuntu

(with a mildly condescending tone)

Step 0 (optional)

You can enable fancy optimizations by creating a config.site file. To do this, open your favorite text editor and type:

To remove a submodule you need to:

Delete the relevant section from the .gitmodules file.
Stage the .gitmodules changes git add .gitmodules
Delete the relevant section from .git/config.
Run git rm --cached path_to_submodule (no trailing slash).
Run rm -rf .git/modules/path_to_submodule (no trailing slash).
Commit git commit -m "Removed submodule "
Delete the now untracked submodule files rm -rf path_to_submodule

Hosted PAB setup

This document describes how to prepare hosted PAB deployment from scratch that can operate on Alonzo purple testnet.

The following required to be run on host machine to use PAB with contracts in hosted scenario on testnet (for 2020-11-05 PAB Release):

Cardano node connected to Alonzo testnet
cardano wallet connected to node
chain-index connected to node
PAB executable connected to node, cardano-wallet and chain-index

Note: we are using somewhat more involved setup with a bit custom docker compose, and wallet and chain-index being built from sources, but there is ready to go node+wallet docker solution available

Debugging Plutus

This example illustrates manually passing serialized data from a Plutus validator and then deserializing it. It uses Plutus.Debug.

Instrument the validator

Change traceIfFalse to Plutus.Debug.debugIfFalse with added arguments containing the data to be passed out of the script. Here we change

traceIfFalse "R" $ any (checkScriptOutput addr hsh value) allOutputs

	object Main extends App {
	AvoidLosingGenericType.run()
	AvoidMatchingOnGenericTypeParams.run()
	TypeableExample.run()
	TypeTagExample.run()
	}

	class Funky[A, B](val foo: A, val bar: B) {
	override def toString: String = s"Funky($foo, $bar)"
	}
