Go Wetware

Wetware node implementation and client libraries for Go programmers.

Installation

The latest binaries can be installed by running go install github.com/wetware/cmd.

For the smoothest developer experience, we encouraged you to check that $GOPATH is set and that $GOPATH/bin is in your $PATH.

Building from Source

This section is for people who are hacking on Wetware itself. If you're just using Wetware, you don't need to read this.

Before starting, it is recommended configure your shell to add $GOPATH/bin to your PATH, if you have not done so already.

One-Liner

You can perform the entire step-by-step build in once command.

$ make

Step-by-Step

Start by installing the binary to your $GOPATH/bin.

$ make install  # requires $GOPATH/bin to be part of $PATH

Then, publish the top-level repo to IPFS, so that we can later navigate down to the desired main.wasm.

$ make publish

Your output should look similar to this, but possibly with different hash values:

go generate ./...
ipfs add -r .

The hash of the top-level go directory is the last line in the above. If you cloned the repo under a different name, you will see a different directory name and a different hash.

Copy it and assign it to ROOT_CID.

ROOT_CID=<hash-you-copied>  # e.g. QmTK1JSQnzsYfbrTWn359jtYBAeVAHtfknWa2Hgikinxjy

Now start a wetware node. Note the path.

$ww run -load "/ipfs/QmWXvzjDBwjFcbLyiDZduqjk3RSxzfEkk5gn9uNX841XYR/system/cmd/nop"

Building WASM Components

WASM artifacts are built by running go generate ./....

WASM artifacts are into the main application or employed during testing. The build-chain is managed by go:generate directives. See examples/hello-world/main.go for one such example.

Application

The main application is built by running go build cmd/main.go -o ww. New or modified WASM components will need to be (re)built beforehand.
