Clojars MELPA Travis Dependencies Status

Handles all your issue tracking tools and version control systems for you!

The Flower library is a set of common protocols for repositories, task trackers, and messaging systems that includes integrations with the most common ones like Jira, TFS, GitLab, GitHub, and Exchange. It may be useful for creating external automation scenarios.

Initially, it was designed to handle all routine operations of the PT Application Firewall development team:

  • Merge opened interlinked pull requests in different GitLab repositories or servers, once MRs are marked with 'LGTM', and then close issues in TFS.
  • Notify about team members' birthdays.
  • Create email requests to the company’s IT Helpdesk in order to give access rights to new team members.
  • Search for current 'In Progress' issues from the CLI.
  • And much more.

If you need separate Python libraries with similar functionality, you may visit DevOpsHQ.


To install, add the following to your project :dependencies:

[flower "0.4.7"]

Or use the Leiningen template to build a new application from scratch:

lein new flower my-flower-application

To install Flower as Emacs package, set up MELPA and then do the following:

M-x package-install [RET] flower [RET]


This library supports multiple integrations with various systems related to development flow.

So the best way to showcase its potential is to demonstrate how it handles each of them by example. We will keep adding to the existing examples upon introducing new functionality.

However, there is a certain caveat you should be aware of before we go any further. Any function in the library may be considered pure (except ones having exclamation marks) only on the top level. Underlying code implicitly uses cache that may be explicitly cleared by a user after each query if so needed. To do it, the user needs to rebind flower.common/*behavior-implicit-cache* variable using flower.macros/without-implicit-cache macro or call (function-name-clear-cache!) where function-name is a function defined with the flower.macros/public-definition macro.

For the impatient

(require 'flower.tracker.core)

;; Print all opened tasks in our task tracker
(let [url ""]
  (doall (map (comp (partial apply println)
                    (juxt :task-type :task-id :task-title))
              (.get-tasks (flower.tracker.core/get-tracker url))))

For Emacs users

(require 'flower)

;; Each element of `flower-tracker-queries` vector has the following format:
;; * Tracker URL or nil if only query changed
;; * Use tracker without auth if nil or with default auth otherwise - see Flower auth
;; * Tracker query or nil for default query if applicable
(setq flower-tracker-queries [("" nil nil)
                              ("" nil nil)])

(add-hook 'org-mode 'flower-mode)

(global-set-key (kbd "C-c f f") 'flower-list-tasks)
(global-set-key (kbd "C-c f t") 'flower-show-task-info)

Activate Flower with:

  • C-c f f to view or update the task list for the current query.
  • C-c f t to view information on a specific task.
