Motoko Compiler(moc) version manager

Motoko Compiler(moc) version manager

Quick Start

One-time initialization

npx mocv init

Select moc version

npx mocv

Use in GitHub workflows

Simply add this step

- name: Select moc version
  run: npx mocv use 0.9.2

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

Setup

Install mocv

npm i mocv -g

Set env var DFX_MOC_PATH

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

mocv init

Or you can add by yourself:

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

export DFX_MOC_PATH=<result>/moc

Usage

Select moc version

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

mocv

or

mocv use 0.8.4

or

mocv use latest

Done!

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

Other use cases

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

DFX_MOC_PATH=$(mocv bin 0.8.3)/moc dfx deploy my_canister

Reset

Revert changes made by mocv init

mocv reset

mocv's Issues

add zsh support

currently this only writes to .bashrc, ideally the current shell will be detected and the env variable written to the respective rc file

Update binary names

dfinity/motoko#3997

auto run `init` first time

To be able to start using with just: npx mocv or npx mocv use latest

Master version

Hi ZenVoich,

Today came across your version manager, pretty good.

Can't stop being impressed with your good work.

I now will need to pull the latest version (master) of motoko. For development purposes.

There isn't any easy way yet to get it right?

Maybe it would be a good feature to add, would you consider?

Thanks,
Tiago
