[Enhancement] One-liner kangaroo build from standard holochain nix shell

[mattyg]

Just wanted to float the idea of making a kanagroo build a one-line command from your scaffolded app within its nix-shell.

Thanks really love this

I was thinking about this as well... a few points worth considering here:

• If you're only talking about a single build, without code generation, it would not allow cross-platform builds over CI. Also certain things would probably not be feasible with one command (e.g. auto-updating feature)
• If you're talking about scaffolding the kangaroo code, I see a problem in pulling in updates from upstream, which is way more easy when forking the kangaroo and making pull requests from the parent repository

I'm thinking you could just re-generate the kangaroo from the latest source whenever there are updates, but I guess that would mean a lot of unnecessary rust building.

i.e. a script like this:

git clone <kangaroo-repo> ./kangaroo
npm run package
rsync workdir/*.happ ./kangaroo/pouch
rsync ui/dist.zip ./kangaroo/pouch/ui.zip
find ./kangaroo -type f -exec sed -i 's/replace-me/MY-HAPP-NAME/g' {} \;

Although we'd probably want something more complex than just doing a big search and replace -- probably want to move the kangaroo configuration to an external file you can keep in the repo, and then you can easily re-generate the same kangaroo from that configuration file.

But yeah we definitely still need the github actions for building the packages for different platforms. With this idea, those actions would be included of your normal app repo (which could generate the kanagroo & build it in CI).

Hmm interesting, it does sound like a nice idea yes.
