Coding Guideline
================

The following is not mandatory but shows some best practices:

Constants
---------

* Define constants in ``Extensions > QFQ > Custom > ...``

* Dynamic values under ``Extensions > QFQ > Dynamic > ...``


QFQ content record
------------------

* Name the record in the header field with:

  * Regular content: ``[QFQ] ...``
  * Content in the left column: ``[QFQ,L] ...``
  * Content in englisch: ``[QFQ,E] ...``

* The first lines should be comments, explaining what the record does and list all passed variables. Optional variables
  are indicated by using STORE_EMPTY or STORE_ZERO::

    #
    # Shows list of Persons living in {{country:SE}}
    #
    # {{country:SE}}
    #

* A good practice is to define all possible STORE_SIP Parameter in a SQL at the beginning and copy them to STORE_RECORD::

      10 {
        # Normalize variables
        sql = SELECT '{{country:SE}}' AS _country

        # List selected persons per country
        20.sql = SELECT p.name FROM Person AS p WHERE p.country LIKE '{{country:R}}'
      }

* Always comment the queries like shown above.

QFQ Form
--------

* Mandatory SIP parameter should to be mentioned in Form.requiredNew and/or Form.requiredEdit.
* If the title of a FormElement isn't descriptive enough, use tooltip, note or extraButtonInfo to explain to a user.
* Every Form should show a descriptive title to identify the task and current record. E.g. Not 'Person' but 'Person: John Doe'.
* Often the length of a pill title if not sufficient, use a tooltip to give a more descriptive hint.
