Composer SemVer

Static linked CLI wrapper for composer/semver.
Parsing and validating versions exactly like Composer does without installing PHP.

Built with ♥ by Typist Tech

Usage

Normalize Versions

Normalizes a version string to be able to perform comparisons on it. This is a wrapper of the Composer\Semver\VersionParser::normalize() method.

$ composer-semver normalize '1.2-p.5+foo'
1.2.0.0-patch5

# Status code 0 means valid versions
$ echo $?
0

$ composer-semver normalize 'not-a-version'

 [ERROR] Invalid version string "not-a-version"

# Non-zero status codes mean invalid versions
$ echo $?
1

$ composer-semver normalize --help
Description:
  Normalizes a version string to be able to perform comparisons on it

Usage:
  normalize [options] [--] <version>

Arguments:
  version

Options:
      --full-version=FULL-VERSION  Complete version string to give more context.
  -h, --help                       Display help for the given command. When no command is given display help for the list command
      --silent                     Do not output any message
  -q, --quiet                      Only errors are displayed. All other output is suppressed
  -V, --version                    Display this application version
      --ansi|--no-ansi             Force (or disable --no-ansi) ANSI output
  -n, --no-interaction             Do not ask any interactive question
  -v|vv|vvv, --verbose             Increase the verbosity of messages: 1 for normal output, 2 for more verbose output and 3 for debug

Help:
  This is a wrapper of the Composer\Semver\VersionParser::normalize() method.

Parse Constraints

Parses a constraint string and strip its ignorable parts. This is a wrapper of the Composer\Semver\VersionParser::parseConstraints() method.

$ composer-semver parse '>=1.2 <2.0 || ~3.4.5 || ^6.7'
[[>= 1.2.0.0-dev < 2.0.0.0-dev] || [>= 3.4.5.0-dev < 3.5.0.0-dev] || [>= 6.7.0.0-dev < 7.0.0.0-dev]]

# Status code 0 means valid constraints
$ echo $?
0

$ composer-semver parse '~>1.2'

 [ERROR] Could not parse version constraint ~>1.2: Invalid operator "~>", you probably meant to use the "~"
         operator

# Non-zero status codes mean invalid constraints
$ echo $?
1

$ composer-semver parse --help
Description:
  Parses a constraint string and strip its ignorable parts

Usage:
  parse <constraints>

Arguments:
  constraints

Options:
  -h, --help            Display help for the given command. When no command is given display help for the list command
      --silent          Do not output any message
  -q, --quiet           Only errors are displayed. All other output is suppressed
  -V, --version         Display this application version
      --ansi|--no-ansi  Force (or disable --no-ansi) ANSI output
  -n, --no-interaction  Do not ask any interactive question
  -v|vv|vvv, --verbose  Increase the verbosity of messages: 1 for normal output, 2 for more verbose output and 3 for debug

Help:
  This is a wrapper of the Composer\Semver\VersionParser::parseConstraints() method.

Print Bundled PHP and composer/semver Versions

$ composer-semver --version

Dump Shell Completion Scripts

For shell completions, follow the instructions from:

$ composer-semver completion --help

If you installed Composer SemVer via Homebrew, completion scripts are managed by Homebrew. Read more at https://docs.brew.sh/Shell-Completion

Tip

Hire Tang Rufus!

I am looking for my next role, freelance or full-time. If you find this tool useful, I can build you more weird stuff like this. Let's talk if you are hiring PHP / Ruby / Go developers.

Why

Which version numbering system does Composer itself use?

Composer uses Semantic Versioning (aka SemVer) 2.0.0.

-- Composer FAQ

Under the hood, Composer uses composer/semver to parse and validate versions.

Despite the lie on Composer FAQ, the fragmentary documentation, and the deceitful package name composer/semver, Composer implements only a subset of Semantic Versioning specification while supports some uncommon versioning schemes. Working with Composer packages versions without composer/semver is a bit tricky.

"A bit tricky" is an understatement.

Composer SemVer wraps composer/semver and the PHP runtime as a static linked CLI tool, so you can work with the package versions exactly like Composer does without installing PHP.

Tip

Hire Tang Rufus!

There is no need to understand any of these quirks. Let me handle them for you. I am seeking my next job, freelance or full-time.

Installation

Homebrew (macOS / Linux) (Recommended)

brew tap typisttech/tap
brew install typisttech/tap/composer-semver

apt-get (Debian based distributions, for example: Ubuntu)

curl -1sLf 'https://dl.cloudsmith.io/public/typisttech/oss/setup.deb.sh' | sudo -E bash
sudo apt-get install composer-version

Instead of the automatic setup script, you can manually configure the repository with the instructions on Cloudsmith.

Manual .deb (Debian based distributions, for example: Ubuntu)

Warning

If you install the .deb file manually, you have to take care of updating it by yourself.

Download the latest .deb file from GitHub Releases, or via gh:

# Both arm64 (aarch64) and amd64 (x86_64) architectures are available.
gh release download --repo 'typisttech/composer-semver' --pattern 'composer-semver_linux_arm64.deb'

Optionally, verify the .deb file:

gh attestation verify --repo 'typisttech/composer-semver' 'composer-semver_linux_arm64.deb'

Finally, install the package:

sudo dpkg -i composer-semver_linux_arm64.deb

Manual Binary

Warning

If you install the binary manually, you have to take care of updating it by yourself.

Download the latest .tar.gz file from GitHub Releases, or via gh:

# Both darwin (macOS) and linux operating systems are available.
# Both arm64 (aarch64) and amd64 (x86_64) architectures are available.
gh release download --repo 'typisttech/composer-semver' --pattern 'composer-semver_darwin_arm64.tar.gz'

Optionally, verify the .tar.gz file:

gh attestation verify --repo 'typisttech/composer-semver' 'composer-semver_darwin_arm64.tar.gz'

Finally, unarchive and move the binary into $PATH:

tar -xvf 'composer-semver_darwin_arm64.tar.gz'

# Or, move it to any directory under `$PATH`
mv composer-semver /usr/local/bin

Alternatives

• ComVer
  A failed attempt to re-implement composer/semver in Go. It only supports a subset of Composer versioning.
