versiony

Node.js module to increment version number for your code/module

Installation

npm install versiony

If you want to use the CLI, install

npm install -g versiony-cli

Usage

Versiony can read code versions from json files containing either the keys "major", "minor", "patch"

{
  "major": 0,
  "minor": 1,
  "patch": 1
}

or with a "version" key, just like package.json

{
  "name": "versiony",
  "version": "0.1.1"
}

Example

version.json

{
  "major": 0,
  "minor": 0,
  "patch": 1
}

test.js

var versiony = require('./index')
 
versiony
 
  .minor()                // will cause the minor version to be bumped by 1
  .from('version.json')   // read the version from version.json
  .to()                   // write the version to the source file (package.json)
                          // with the minor part bumped by 1
  .to('bower.json')       // apply the same version
  .to('package.json')     // apply the same version
  .end()                  // display info on the stdout about modified files

The above code will cause the version 0.1.1 to be written to all 3 files, if all are found.

In the case versiony does not find a file that is specified in the to() call, it just skips it.

Other examples

Set the patch version number to 4. That is, for a current version 1.0.2 will write 1.0.4

versiony
  .from('package.json')
  .patch(4)
  .to()

Take the version in version.json. For this version, set the major version to 1, then write this to package.json and bower.json. So, for version.json containing "4.5.6" the script below will write 1.5.6 to package.json and bower.json. If you also want to update version.json, simply add a .to('version.json') call anywhere after the .major(1)

versiony
  .from('version.json')
  .major(1)
  .to('package.json')
  .to('bower.json')
  .end()

Copy the version from one file to another

  versiony.from('version.json').to('package.json')

Release a new major version

versiony
  .from('version.json')
  .major()
  .minor(0)
  .patch(0)
  .to()               // also write to the source file (the one specified in from() )
  .to('bower.json')
  .to('package.json')
  .end()

Which is equivalent to

versiony
  .from('version.json')
  .newMajor()
  .to()
  .to('bower.json')
  .to('package.json')
  .end()

The flow in the above script is the following

• take the version from version.json
• apply the modifications (increment major, set minor and patch to 0)
• write the new version to the source file (version.json)
• write the new version to bower.json
• write the new version to package.json

API

Each of the methods below, except get() and end() return the versiony object.

major()

Causes the current major version to be incremented by 1

major(value)

Sets the current major version to have the specified value

minor()

Causes the current minor version to be incremented by 1

minor(value)

Sets the current minor version to have the specified value

patch()

Causes the current patch version to be incremented by 1

patch(value)

Sets the current patch version to have the specified value

preRelease()

Causes the last section of the dot-delimited pre-release tag to be incremented by 1 (e.g. 1.2.3-beta.3 becomes 1.2.3-beta.4)

preRelease(value)

Sets the current pre-release version to have the specified value. If the value is falsy (but not undefined), then any existing pre-release tag will be removed (e.g. 1.2.3-beta.3 becomes 1.2.3)

NOTE Calling major() twice does not cause the increment to be applied twice. It is only applied once. Same for minor(), patch(), and preRelease()

newMajor()

Equivalent to calling major().minor(0).patch(0).preRelease('')

newMinor()

Equivalent to calling minor().patch(0).preRelease('')

from(file)

Sets the current version. This clears any values set using major(value), minor(value) and patch(value). It does not clear increments set with major(), minor() and patch()

with(file)

Same as from(file), but also writes the version back to file, if previously increments have been used.

Example - increment the major version

versiony
  .major()
  .with('package.json')

to(json_file)

Causes the version to be written to the specified file. If the specified json file has a "version" key, the version will be written to that key. If it has "major", "minor" and "patch" keys, the value will be written to those.

to()

Writes the value to the source file (the file that was used with .from() or .with() ). If no initial file specified, it simply returns.

version(v: String/Array)

Sets the current version. This clears any value set using major(value), minor(value), patch(value), as well as their incrementive forms ( major(), minor(), patch() )

Example: sets version 4.0.0

versiony
  .major()
  .version('4.0.0')
  .to('package.json')

is equivalent to

  versiony
    .version('4.0.0')
    .to('package.json')

end()

Clears any version and outputs the files that have been updated. Calling it is totally optional. Returns an object with info about the version and the changed files.

versiony.
  version('4.5.6')
  .major()
  .to('package.json')
 
var info = versiony.end()
console.log(info.version)
console.log(info.files)

get()

Returns the current version.

var v = versiony
          .version('1.0.0')
          .patch()
          .get()
 
console.log(v)  // '1.0.1'

CLI

Usage

Install with

npm install -g versiony-cli

Example: increment the minor version

versiony package.json --minor

The source file defaults to package.json, so you can easily skip it, if that's what you're using.

Example: set the major version to 3 (in package.json)

versiony --major=3

Example: set specific version

versiony --version=1.2.3

Example: update multiple files

versiony --patch --to=package.json,bower.json

Example: release new major update (bumps major and sets minor and patch to 0)

versiony --newmajor

Example: release new minor update (bumps minor and sets patch to 0)

versiony --newminor
