Experimental protobuf plugin generating elm code to decode/encode Proto3/JSON from proto definitions.
The plugin itself is written in Go, and it requires the base protoc
protobuf
compiler to be installed on the system.
For a sample generated output file, see Repeated.elm.

The simplest way to install the plugin is to download a pre-compiled binary from
https://github.com/tiziano88/elm-protobuf/releases , then unpack it and copy or
move the protoc-gen-elm
binary somewhere in your $PATH
.
Make sure that you have a Go environment correctly set up, and that
$GOPATH/bin
is included in your $PATH
. See
https://golang.org/doc/install for info.
Install a recent protoc
compiler version from
https://github.com/google/protobuf (it must have support for proto3
format).
Obtain the protoc-gen-elm
binary using go get
:
go get github.com/tiziano88/elm-protobuf/protoc-gen-elm
Run the protoc
compiler specifying the --elm_out
flag:
protoc --elm_out=. *.proto
protoc
will automatically detect the protoc-gen-elm
binary from your $PATH
and use it to generate the output elm code.
Then, in your project, add a dependency on the runtime library:
elm install tiziano88/elm-protobuf
