POC for a Locutus based Proposal Assessment system

Prerequisites

Development Environment (NIX Shell)

This is the preferred development environment.

  1. Install NIX : https://nixos.org/download.html
  2. Start a nix development environment (From the repo Root): nix develop

Development Environment (Manual)

~~ NOT RECOMMENDED ~~

  1. Install LLVM
  2. Install NPM
  3. Install the typescript package:
    • globally by running:
      • npm install typescript@latest -g
    • or use the npx command with the --package flag, e.g.
      • npx --package typescript tsc --init
    • Make sure it works:
      • tsc --version
    • If it doesn't run:
      • npm config get prefix
      • And make sure that path is in your $PATH.
  4. Install webpack:
    • npm install --global webpack
    • npm install --global webpack-cli
  5. Install msgpack & bs58 libraries:
    • npm install @msgpack/msgpack
    • npm install bs58

Install Extra Packages/Tools

This only needs to be done once when the development environment is created.

  1. cargo install cargo-make : see https://github.com/sagiegurari/cargo-make
  2. cargo make install-prereqs

Installing Source

Locutus is still under heavy development, so for now we include a locutus fork as a submodule. This will allow us to easily contribute any necessary patches upstream, until the locutus project stabilises.

To checkout, and initialize with the upstream locutus fork:

git clone --recurse-submodules git://github.com/...TODO...

If you forgot to add --recurse-submodules, then after checkout just run:

git submodule update --init

Building

Make sure you are in a Nix dev shell: nix develop

  1. Build the Locutus Tools: cargo make build-locutus

Ignore this stuff ---

  1. Build the latest ldt tool:
    • make build-tool
$ cd locutus/docker
$ docker compose build
...
$ cd ../..


$ CONTRACT_SRC_DIR=./contracts/posts/ ./locutus/docker/ldt.sh build
$ ./locutus/docker/ldt.sh publish --code contracts/posts/build/locutus/poc_proposal_assessment_posts.wasm --state contracts/posts/build/locutus/contract-state
PROJECT_SRC_DIR=/home/<something>/poc_pa_system <- Root of the Project being build
CONTRACT_SRC_DIR=/home/<something>/poc_pa_system  <- Relative DIR under PROJECT_SRC_DIR to the Contract to build
Putting contract FwiG1DsyEHbvtsQaE6qrT5jbSD8vhwaQqSWCSchdWha2
$ CONTRACT_SRC_DIR=./web ./locutus/docker/ldt.sh build

$ cd locutus/docker
$ docker compose up
