Motoko Compiler(mocp) version manager

Quick Start

One-time initialization

npx mocp init

Select mocp version

npx mocmp

Use in GitHub workflows

Simply add this step

- name: Select mocp version
  run: npx mocmp use 0.9.2

Instead of 0.9.2 you can specify any other mocp version or latest

Setup

Install mocmp

npm i mocmp -g

Set env var DFX_MOC_PATH

This command adds a line to .bashrc to set DFX_MOC_PATH to the current moc version

mocmp init

Or you can add by yourself:

Run mocmp bin current, copy result and add the line below to your .bashrc

export DFX_MOC_PATH=<result>/moc

Usage

Select mocp version

You will be prompted to select one of the available mocp versions

mocmp

or

mocmp use 0.8.4

or

mocmp use latest

Done!

Now dfx will use current mocp version when you build canisters with dfx build or dfx deploy

Other use cases

If you want to use specific version of mocp to deploy a canister:

DFX_MOC_PATH=$(mocmp bin 0.8.3)/mocp dfx deploy my_canister

mocmp reset
