Hello World
This is a demo of Gno smart contract programming. This document was constructed by Gno onto a smart contract hosted on the data Realm name "gno.land/r/demo/boards" (github).
Starting the gnoland node node/validator.
NOTE: Where you see --remote localhost:26657 here, that flag can be replaced
with --remote localhost:26657 for local testnets.
build gnoland.
1git clone git@github.com:gnolang/gno.git
2cd ./gno
3make
add test account.
1./build/gnokey add test1 --recover
Use this mnemonic:

start gnoland validator node.
1./build/gnoland
(This can be reset with make reset).
start gnoland web server (optional).
1go run ./gnoland/website
Signing and broadcasting transactions.
publish the "gno.land/p/demo/avl" package.
1./build/gnokey maketx addpkg test1 --pkgpath "gno.land/p/demo/avl" --pkgdir "examples/gno.land/p/demo/avl" --deposit 100ugnot --gas-fee 1ugnot --gas-wanted 2000000 > addpkg.avl.unsigned.txt
2./build/gnokey query "auth/accounts/g1jg8mtutu9khhfwc4nxmuhcpftf0pajdhfvsqf5"
3./build/gnokey sign test1 --txpath addpkg.avl.unsigned.txt --chainid "portal-loop" --number 0 --sequence 0 > addpkg.avl.signed.txt
4./build/gnokey broadcast addpkg.avl.signed.txt --remote localhost:26657
publish the "gno.land/r/demo/boards" realm package.
1./build/gnokey maketx addpkg test1 --pkgpath "gno.land/r/demo/boards" --pkgdir "examples/gno.land/r/demo/boards" --deposit 100ugnot --gas-fee 1ugnot --gas-wanted 300000000 > addpkg.boards.unsigned.txt
2./build/gnokey sign test1 --txpath addpkg.boards.unsigned.txt --chainid "portal-loop" --number 0 --sequence 1 > addpkg.boards.signed.txt
3./build/gnokey broadcast addpkg.boards.signed.txt --remote localhost:26657
create a board with a smart contract call.
1./build/gnokey maketx call test1 --pkgpath "gno.land/r/demo/boards" --func CreateBoard --args "testboard" --gas-fee 1ugnot --gas-wanted 2000000 > createboard.unsigned.txt
2./build/gnokey sign test1 --txpath createboard.unsigned.txt --chainid "portal-loop" --number 0 --sequence 2 > createboard.signed.txt
3./build/gnokey broadcast createboard.signed.txt --remote localhost:26657
Next, query for the permanent board ID by querying (you need this to create a new post):
1./build/gnokey query "vm/qeval" --data "gno.land/r/demo/boards.GetBoardIDFromName(\"testboard\")"
create a post of a board with a smart contract call.
1./build/gnokey maketx call test1 --pkgpath "gno.land/r/demo/boards" --func CreatePost --args 1 --args "Hello World" --args#file "./examples/gno.land/r/demo/boards/README.md" --gas-fee 1ugnot --gas-wanted 2000000 > createpost.unsigned.txt
2./build/gnokey sign test1 --txpath createpost.unsigned.txt --chainid "portal-loop" --number 0 --sequence 3 > createpost.signed.txt
3./build/gnokey broadcast createpost.signed.txt --remote localhost:26657
create a comment to a post.
1./build/gnokey maketx call test1 --pkgpath "gno.land/r/demo/boards" --func CreateReply --args 1 --args 1 --args "A comment" --gas-fee 1ugnot --gas-wanted 2000000 > createcomment.unsigned.txt
2./build/gnokey sign test1 --txpath createcomment.unsigned.txt --chainid "portal-loop" --number 0 --sequence 4 > createcomment.signed.txt
3./build/gnokey broadcast createcomment.signed.txt --remote localhost:26657
1./build/gnokey query "vm/qrender" --data "gno.land/r/demo/boards:testboard/1"
render page with optional path expression.
The contents of https://gno.land/r/demo/boards: and https://gno.land/r/demo/boards:testboard are rendered by calling
the Render(path string) function like so:
1./build/gnokey query "vm/qrender" --data "gno.land/r/demo/boards:testboard"
