Conventions for Mapbender3

Code conventions

  • variable names / way of coding
  • Code documentation
  • trans convention - where to put translation
  • document the x steps on the way to a new functionality
    • define the topic
    • create a ticket
    • create a workflow
    • discuss the workflow with the core team and find a final solution

    • test
    • documentation in mapbender-documentation –> rst
    • close the ticket
  • where to put a module/element
  • naming vor files (referred to symfony convention)

Git branch conventions

We follow the Git Flow branching model (Read more about it in the original document describing it). Basically that boils down to having at least two branches:

  • develop - for the daily work, always has the latest merged commits, and is equal to or ahead of the latest release
  • master - only changes on new releases (right now and until the 3.0.1 release, some of our repositories don’t have a master branch but will get one then again)

Furthermore there might be more branches, which must always be namespaced:

  • feature/<name> - Used for developing new features (feature/printservice)
  • hotfix/<name> - Used for making hot fixes for releases (hotfix/bug_123)
  • release/<name> - Used for preparing releases, very short-lived (release/3.0.1)

Some Linux distributions have a package called git-flow which will provide easy git command shortcuts to use the merge/branch model of Git Flow without having to do everything by yourself (which is still possible and you should always know how Git Flow uses plain git to achieve things).

Layout conventions

What to keep in mind, when you create a layout

  • naming conventions
  • where to put the css
  • where to put the twig
  • where to put the images / should be possible to easy switch an image collection an get other buttons

Translation where

  • conventions to put the files? Groß-Kleinschreibung/ welche Übersetzungen werden generell gepflegt? en/de weitere?
  • also have a look at Translation in Mapbender3 <../translation.rst>

Issue conventions

Issues (bugs and features) are administrated in the mapbender-repository at:

We create a milestone for every version of Mapbender3:

There are some rules you should keep in mind:

  • write understandable tickets!!
  • write your title so that the issue is already described in the title:
  • write comments with all necessary information: * for bugs: describe step by step how the error can be reproduced * for features: describe feature and functionality
  • when you create a new ticket do not assign it to a milestone or developer, if you are not sure
  • add labels to your ticket * bug - describes a bug that orrurs in a special version of Mapbender3 (add info about the version) * feature - new feature * enhancement - stands for feature enhancement * wip - work in progress
  • when you work on a ticket or close it please assign a user and milestone
  • when you close a ticket, please:
    • add a comment in the ticket and refer to the commit,
    • refer to the documentation at or a demo if possibile.

Version conventions

The Mapbender3 version is defined by a four digit numbering system, seperated by dots.

  • The first digit is constant and represents the Mapbender3 software cycle.
  • The second digit describes all new features and major changes in Mapbender3, with

the highest difficulty level of a update process.

  • The third digit describes new features and minor changes, which can be easily updated.
  • The fourth digit represents only bugfixes and micro changes.

Increase a digit means always a reset for all digits before. For example - ->
