rebar3_hex
rebar3_hex is a plugin for Rebar3 that bundles providers to interact with Hex.
💡 rebar3_hex is a tool for package authors If your Erlang project is not meant to be published on Hex, Rebar3 itself should be enough for you.
Setup
Add to your global rebar3 config in ~/.config/rebar3/rebar.config
:
{plugins, [rebar3_hex]}.
Alternatively, you can add to your project's rebar3 config in project plugins :
{project_plugins, [rebar3_hex]}.
NOTE : Be sure not to add rebar3_hex
to the plugins section within a projects rebar3 config as this will
become a dependency for others downloading your package from hex.pm
Documentation
rebar3_hex by default expects you to configure a documentation provider. We recommend using rebar3_ex_doc for publishing documentation along with your package for a consistent format and style on hex.pm.
Example :
{ex_doc, [
{extras, ["README.md", "LICENSE"]},
{main, "README.md"},
{source_url, "https://github.com/namespace/your_app"}
]}.
{hex, [{doc, ex_doc}]}.
Alternatively, or on Erlang versions older than OTP-24, you can use the edoc provider that ships with rebar3 :
{hex, [{doc, edoc}]}.
Basic usage
You should read the docs for a complete over for each provider, but below is a brief overview of basic usage.
Authenticating User
If you already have a user for hex.pm run:
$ rebar3 hex user auth
Note that this will ask for your hex.pm username and password, as well as a password for encrypting your api token that has write permissions to the repository. When publishing a package you will have to give this password to decrypt the token in order to publish.
See the docs for more information.
Building
The build
provider is very useful for seeing exactly what would be published using either the publish
or cut
task
without any chance of actually publishing the package or docs. Tarballs for the package and docs are written to
_build/<profile>/lib/your_app/hex/
by default.
$ rebar3 hex build
See the docs for more information.
Publishing
Two providers are available for publishing packages, publish
and cut
By default publish
builds and pushes your package and docs to a repository. See the
docs for more information.
$ rebar3 hex publish
cut
is available to provide some additional functionality around versioning and git tags. See the
docs for more information.
$ rebar3 hex cut
In either case, both providers will display the details of what is being published (what files, the version, dependencies) and ask if it should continue, so be sure to read the output carefully and make sure it is publishing what you expected.
Managing package owners
Owners can be added, removed, and listed for packages you are an owner of with the hex owner
command. Packages
can also be transfered to other registered users on hexpm as well.
$ rebar3 hex owner [add | remove | list | transfer] <package> <email>
See the docs for more information.
Retiring packages
Packages can be flagged as retired on hexpm via the retire
provider :
$ rebar3 hex retire PACKAGE VERSION REASON --message
They can also be unretired in case a mistake was made :
$ rebar3 hex retire PACKAGE VERSION --unretire
See the docs for more information.
Organizations
rebar3_hex supports working with organizations via the organization
provider.
Simply add your organization to either your global rebar.config (i.e., ~/.config/rebar3/rebar.config
) or a local
project rebar.config.
{hex, [{repos, [#{name => <<"hexpm:your_org">>}]}]}.
You can then authenticate with with the organization repository. Be sure you have already authenticated with the main repository first:
$ rebar3 hex auth # make sure you're authenticated to the main repo first
$ rebar3 hex organization auth hexpm:your_org # authenticate to the org
Now you can generate, revoke, and list keys for your organizations. See below for an example of generating a key for use in CI.
See the docs for more information.
Read-Only Repo Key for CI
If you have a private organization or other private repository it is recommended that you use a repo specific auth token for reading from the repository in CI. To generate a token:
$ rebar3 hex organization auth hexpm:myrepo
Successfully authenticated to hexpm:myrepo
Now you can generate a key to use in CI for your organization
$ rebar3 hex organization key hexpm:myrepo generate
abc123
Then in CI use whatever method is available for setting an environment variable to the token and add this call at the
beginning of your CI runs to add the token to your rebar3 hex config. Below we'll use the environment REPO_KEY
as an
example.
$ rebar3 hex organization auth hexpm:myrepo --key $REPO_KEY
Searching hexpm
A search
provider is available to search packages across hex.pm as a convenience.
$ rebar3 hex search
