bumpversion v0.1.3

bumpversion

Bump the version to a json file (VERSION.json)

Getting Started

Install the module with: npm install bumpversion

After the installation, you can run

$ bumpversion -m v0.1.1 -c 1

And it would return would something like

version bumped to:
 {
    "cache": 1,
    "timestamp": "2013-06-03T03:57:17.273Z",
    "main": "v0.1.1"
}

Meanwhile, a file named VERSION.json would be created with same content.

VERSION.json

• main A string field, indicating the main version. Could be something like "release/v1.2.3"
• cache A integer field indicating the cache version. A good usercase of this field is CDN versioning. If you do not specify "-c", this field would be self increment.
• timestamp A GMT timestamp indicating when the file being generated.
• last_commits If you are using git, you can call bumpversion -lc 3, it would include last three commits version hash and log message into last_commits.

Examples

If you execute "bumpversion" inside a git repository without specifying "-m", it will automatically take the branch name as main version.

Take git branch as main version.

Now I am inside a git repository:

$ git branch
  develop
  master
* release/0.1.1

Now execute "bumpversion"

$ bumpversion
version bumped to:
 {
    "cache": 5,
    "timestamp": "2013-06-03T03:53:55.972Z",
    "main": "release/0.1.1"
}

Include the last N GIT commit hash / log into VERSION.json

Including last 2 commits

bumpversion -lc 2
version bumped to:
 {
    "cache": 2,
    "timestamp": "2013-06-03T04:16:18.487Z",
    "main": "release/0.1.1",
    "last_commits": [
        "0f0ef3da436f5f5f71dcbf78ce720bcd2ff47e7e version bumped",
        "a9b14b2ee13a532534d8e75e0e83192534cbd8cc Merge branch 'release/0.1' into develop"
    ]
}

Including last 5 commits

bumpversion -lc 5
version bumped to:
 {
    "cache": 3,
    "timestamp": "2013-06-03T04:19:07.317Z",
    "main": "release/0.1.1",
    "last_commits": [
        "0f0ef3da436f5f5f71dcbf78ce720bcd2ff47e7e version bumped",
        "a9b14b2ee13a532534d8e75e0e83192534cbd8cc Merge branch 'release/0.1' into develop",
        "82f901f53fe61fc469c869a5da009aaec26d4b06 include the test",
        "73a5c11f9675f67556ad691f023255761568bf97 misc changes",
        "83c4c440ac4b47fc0d6fbb5f5b84339889e0e075 add package.json"
    ]
}

Usage

Displaying the help

$> bumpversion -h

usage: bumpversion [-h] [-v] [-m M] [-c C] [-q] [-lc LC]

A tool to generate / bump the version to a JSON file.

Optional arguments:
  -h, --help     Show this help message and exit.
  -v, --version  Show program's version number and exit.
  -m M           Update the main version. If you do not specify version
                 number, Main version will be take it as git branch by
                 default.
  -c C           Update the cache version. If you not specify version number,
                 it would be a self increment number
  -q             quiet mode.
  -lc LC         Update the last default commit

Best Practice

bumpversion is particular useful when you use it with git flow / hubflow. You can call bumpversion -lc 2 every time you are about to close your release or hotfix branch, namely (git flow release finish / git flow hotfix finish). It would automatically record take the branch name as main version and include the last commits log into VERSION.json.
