automate build

[aleeusgr]

currently we do cd plutus-apps git checkout nix-shell cd <name> cabal update cabal run

our goal is to get an executable by running nix-build

Later use nix to build docker container

I need to update provide tag --sha256: in project.cabal like so: https://github.com/SIDANWhatever/plutus-cborhex-automation/blob/dca7e78bad6d62838582acf5c3bb40e0d2c2898b/example-validator/cabal.project#L78

you can get tags by using nix-prefetch-github

testing with ghc8104, 924(default), 904

Same error, 8104 builds for a rather long time.

1. in default.nix set compiler-nix-name = "ghc8107";
2. in example-validator.cabal set cabal-version: 3.6

error: https://github.com/input-output-hk/haskell.nix/issues/1767

[aleeusgr]

more tests: nix-shell builds for me. It was building empty shell, run nix-shell default.nix | shell.nix however inside nix-shell, cabal run fails on Win32

[aleeusgr]

Idea: change tag on cardano-wallet | its dependencies

testing:

source-repository-package 
  2     type: git
  1     location: https://github.com/input-output-hk/cardano-wallet
104     --sha256: 4KsuOyNO8XEMIvqiA0LdLZAJX8OFVizuxETGfayZHDQ=
