boot-semver

Semantic Versioning task for boot-clj.

• Provides version task
• Parses a version.properties file to read the current project version. Example content: VERSION=0.1.1-SNAPSHOT
• Writes a new (if changed) Maven compatible version string to version.properties.
• Optionally includes the version.properties file in target output.
• Optionally generates a namespace containing version information.

The following outlines basic usage of the task, extensive testing has not been done. Please submit issues and pull requests!

Usage

Add boot-semver to your build.boot dependencies and require the namespace:

(set-env! :dependencies '[[degree9/boot-semver "X.Y.Z" :scope "test"]])
(require '[degree9.boot-semver :refer :all])

Get the current project version:

boot version

Use the version task when pushing to clojars:

boot version -y inc build-jar push-release

Or use the version task in a deployment process:

(deftask deploy
  "Build boot-semver and deploy to clojars."
  []
  (comp
   (version :minor 'inc)
   (build-jar)
   (push-release)))

Task Options

The version task exposes a bunch of options for modifying the project version during a build pipeline. Each option takes a quoted symbol (ex. 'inc) which should resolve to an available function. This function will be applied to the current value of the project version component.

x major       MAJ  sym  "Symbol of fn to apply to Major version."
y minor       MIN  sym  "Symbol of fn to apply to Minor version."
z patch       PAT  sym  "Symbol of fn to apply to Patch version."
r pre-release PRE  sym  "Symbol of fn to apply to Pre-Release version."
b build       BLD  sym  "Symbol of fn to apply to Build version."
d develop          bool "Prevents writing to version.properties file."
i include          bool "Includes version.properties file in out-files."
g generate    GEN  sym  "Generate a namespace with version information."

The :develop option is provided for development tasks. These tasks will modify the project version number however, this version number will not be written back to the filesystem.

(deftask dev
  "Build boot-semver for development."
  []
  (comp
   (version :develop true
            :minor 'inc
            :pre-release 'snapshot)
   (watch)
   (build-jar)))

The :include option is provided for adding the version.properties file to the output directory.

(deftask dev
  "Build boot-semver for development."
  []
  (comp
   (version :develop true
            :minor 'inc
            :pre-release 'snapshot
            :include true)
   (watch)
   (build-jar)))

The :generate option is provided for building a namespace containing a single variable version which will contain the the current version, it takes the namespace to be generated as input.

(deftask dev
  "Build boot-semver for development."
  []
  (comp
   (version :develop true
            :minor 'inc
            :pre-release 'snapshot
            :generate 'degree9.boot-semver.version)
   (watch)
   (build-jar)))

(ns degree9.boot-semver.version)

(def version "1.4.3")

Continuous Deployment

The latest version of boot-semver now supports continuous versioning and deployment. This allows you to place the version task after the watch task to support updating the project version each time the files are changed. Additionally build-jar, push-snapshot and push-release are provided which support the new version task.

(deftask dev
  "Continuously build and deploy snapshot."
  []
  (comp
   (watch)
   (version :develop true
            :pre-release 'snapshot
            :generate 'degree9.boot-semver.version)
   (build-jar)
   (push-snapshot)))

Helpers

A few helper functions are provided to be used with the version task.

;; Generic
'zero 'one 'two ... 'nine

;; Pre-Release version helpers
'alpha    ;; "alpha"
'beta     ;; "beta"
'snapshot ;; "SNAPSHOT"

;; Build version helpers
'semver-date          ;; "yyyyMMdd"
'semver-time          ;; "hhmmss"
'semver-date-time     ;; "yyyyMMdd-hhmmss"
'semver-date-dot-time ;; "yyyyMMdd.hhmmss"
'git-sha1-full        ;; full git commit string
'git-sha1             ;; short git commit string (7 chars)
