# Versio



Versio (pronounced _vir_-zhee-oh) is a tool that manages your project's

version evolution. It intelligently updates [semantic version

numbers](https://semver.org/) based on [conventional

commits](https://www.conventionalcommits.org/). It can handle

changelogs, project tags, release subdirectories, GPG signing, pull

requests, and more.



Versio is especially intelligent when dealing with

[monorepos](https://en.wikipedia.org/wiki/Monorepo), allowing not only

individual control of each project within the repo, but also managing

dependencies and references among them.



## Getting Started



The fastest way to install is to use one of the pre-built programs from

our [Releases](https://github.com/chaaz/versio/releases). See the

[Installation docs](./docs/installing.md) for more details and alternate

methods to install Versio.



Once installed, try this in your project to create a new release:



```

$ git pull

$ versio init  # this creates .versio.yaml

$ git add .versio.yaml .gitignore

$ git commit -m "build: add versio management"

$ git push

$ versio release

```



We've listed plenty of other [use cases](./docs/use_cases.md) where you

can use Versio in your projects.



## Who's using Versio?



Versio is listed some places, and used by some projects. If you find

Versio in the wild--or if you use it yourself--and it's not shown here,

please submit an [issue](https://github.com/chaaz/versio/issues). We'll

make sure you're mentioned.



We're listed here!



- [Conventional Commits](https://www.conventionalcommits.org/en/about/):

  Versio supports the official conventional comment specification.

- [Awesome Monorepo](https://github.com/korfuri/awesome-monorepo): A

  great collection of tools for handling your monorepo.



We're used here!



- [Versio](https://github.com/chaaz/versio/): Of course we use Versio

  when developing Versio.



## Background



Versio can help automate the release process by updating

[semver](https://semver.org/) version numbers from [conventional

commits](https://www.conventionalcommits.org/), generating a changelog,

and managing dependencies between projects. This frees developers from

having to coordinate among themselves what versions should be assigned.



Versio can also deliver a machine-readable listing of your projects:

where they live, how they're related, what their tags are--this can be

used to help construct other parts of your release process: such as when

you build, test, publish, and deploy.



## How It Works



Many software projects declare their version number in some sort of

manifest file. Node/NPM projects have a "package.json" file, Rust/Cargo

uses "Cargo.toml", Java/Maven has "pom.xml", Python/pip has "setup.py",

Ruby/gem has gemspec files, and so forth. Go projects and Terraform

modules, among others, opt to keep version numbers in VCS tags instead

of a file. However your project is structured, you can list the location

of your projects' version numbers in a Versio config file, and

thenceforth Versio will be able to manage them.



- Versio reads a config file (by default named `.versio.yaml`) in your

  repository, and finds the version number of each project referenced

  there.

- It also reads previous versions of the same config file and version

  numbers, starting at a specific tag (by default: `versio-prev`) in

  your version control history.

- Based on the old versions, current version, and intervening

  conventional commits, Versio will update your projects' version

  numbers.

- Versio will commit and push the updated manifest files, and update the

  `versio-prev` tag.

- Versio can also create or update per-project version tags.

- Versio can generate or update a changelog based on the pull requests

  and commits that have been made since the last release.



## Running



Check out the [Use Cases](./docs/use_cases.md) to learn how to use

Versio via specific use cases--including managing your repo, using

specific flows, or integrating Versio into CI/CD; or look at the [Versio

Reference](./docs/reference.md) for all command-line options and the

format of the `.versio.yaml` config file.



## Features



Versio has some nice features that make it easy to use in your projects;

here are just a few.



### Pull Request Scanning



Versio can use the Git API to group commits by PR in its changelog, and

can even "unsquash" PRs to extract the conventional commits hidden

inside a squashed commit. This process happens automatically for

GitHub-originated repositories. See the [PR

Scanning](./docs/pr_scanning.md) page for more information.



### Version Tags



You can write VCS tags, and use them instead of a manifest file; this is

a common pattern in Go and Terraform projects. To use this feature, you

need to provide the project's tag prefix and a default value. See the

[Version Tags](./docs/version_tags.md) document for details.



### Major subdirectories



Some projects keep major revisions of software in different

subdirectories, usually named `v2`, `v3` etc. This allows developers to

keep track of multiple, sometimes very different application structures

at the same time. You can utilize this feature by providing a `subs`

property in your project configuration. See the [Major

Subdirectories](./docs/subs.md) page for a description.



### Changelog Management



If you're not happy with the default changelog you can write your own

liquid template instead; put it in the project itself, elsewhere in the

filesystem, or serve it from a web service. If that's not enough

flexibility, you can output a JSON document that contains all the

release information, and use that in your own pipeline for custom

actions. Additionally, you can examine the builtin templates, perform a

changelog-only release, or format a release plan using a changelog. The

[Changelog](./docs/changelog.md) page contains more details on this

powerful feature.



### VCS Levels



VCS Levels allow you to control the way Versio interacts with a Git

repository: you can interact only locally, with a remote, or not at all.

See the description in its [document](./docs/vcs_levels.md) for more

information.



### Version Chains



Sometimes a version in one project will depend on a change in another

project, even when both projects are in the same monorepo. Versio allows

you to manage these dependencies, and automatically increment all

dependent versions. See the [Version Chains](./docs/chains.md) document

for more info.



### VCS Signing



You might like to sign your commits or your tags to provide more

security to your users and co-workers. Versio likes security, too!

Versio can read tags and commits that have been signed, and with the

right configuration, will sign its own commits and tags. See the

[Signing](./docs/signing.md) page for how to do this.



## Troubleshooting



There's a whole [Troubleshooting](./docs/troubleshooting.md) document

for tracking down and reporting errors or other unexpected behavior. A

lot of the time, though, it comes down to running Versio with logging

and error tracing activated:



```

RUST_LOG=versio=trace RUST_BACKTRACE=1 versio 

```
