Package does not hold state. They are compartamentalized to make it easier for others to use. Realms hold state, they exist as the "smart contract".
First make sure Go and Git are installed.
Clone the repo and install everything.
git clone https://github.com/gnolang/gno
cd gno && make install
Make sure the installation worked
gnokey --help
When you import, you can import "Go" libraries using a shim called "std".
Use the "Gno" extension, but make sure gofumpt is installed:
go install mvdan.cc/gofumpt@latest
Run tests with gno, from the root directory of gno while working in the packages folder examples/gno.land/p/demo:
gno test --verbose examples/gno.land/p/demo/microblog
gno test --verbose examples/gno.land/p/demo/microblog 2>&1 | grep panic
Since fmt.Print does not exist, use println() and if you need formatting use println(ufmt.Sprintf(...)).
Create an instance (a realm), that will hold state and render.
Create a new folder in examples/gno.land/r/demo/. Write code, with public functions that will be available.
gnokey generate
gnokey add --recover zkey
# enter password
# enter bip39 mnemonic from gnokey generate
you should now have an address.
enter the addresses into genesis_balances.txt.
note: remove gno.land/testdir to reset local instance.
cd gno.land
make build
./build/gnoland
check if address exist
gnokey list
check if funds exist
/build/gnokey query --remote localhost:26657 auth/accounts/<address>
??
cd gno.land
./build/gnoweb
pkgpath is where to deploy the package.
pkgdir is where the source code actually is.
gnokey maketx addpkg --pkgpath "gno.land/p/demo/microblog" --pkgdir "examples/gno.land/p/demo/microblog" --deposit 100000000ugnot --gas-fee 1000000ugnot --gas-wanted 2000000 --broadcast --chainid dev --remote localhost:26657 zkey
gnokey maketx addpkg --pkgpath "gno.land/r/demo/microblog" --pkgdir "examples/gno.land/r/demo/microblog" --deposit 100000000ugnot --gas-fee 1000000ugnot --gas-wanted 2000000 --broadcast --chainid dev --remote localhost:26657 zkey
--arg lists the arguments in order.
gnokey maketx call --pkgpath "gno.land/r/demo/microblog" --func "NewPost" --args "hello, world" --gas-fee "1000000ugnot" --gas-wanted "2000000" --broadcast --chainid dev --remote localhost:26657 zkey
You specify a URL for your realm, like /r/demo/microblog, but what is actually seen as a "path" in your realm is only part after a colon, e.g. http://localhost:8888/r/demo/microblog:test123 has the path test123.
go run ./gnovm/cmd/gno precompile --verbose ./examples && go run ./gnovm/cmd/gno build --verbose ./examples
?? why doesn't ^ work??
?? how do I update an realm/package without creating a new pkgpath?
?? where is the data stored when I run things locally?
?? how do I setup a faucet?
?? what is the gas-fee and gas-wanted?
?? why when I make a gnokey maketx call with a new key does it give an unknown address error, is it because there are no funds for that key?
