The grouping element /package/conditions contains all conditions defined for the Software Pack.

A condition describes dependencies on device, processor, and tool attributes as well as the presence of other components. The conditions are used to define AND and OR rules used to make components conditional and therefore only available under certain circumstances, e.g. for specific devices or processors. The conditions are also used to express dependencies between components.

Each condition has an id that is unique within the scope of a the description. An id can be referenced in the condition attribute of components, apis, examples, files and other conditions to become conditional. If a condition resolves to false during the processing of the description, the respective element will be ignored.

Example:

<conditions>
  <condition id="CM4">                           <!-- defines the condition with the ID "CM4" -->
    <description>True if the active device has a Cortex-M4 processor</description>
    <require Dcore="Cortex-M4"/>                 <!-- device has a Cortex-M4 processor -->
  </condition>
  <condition id="Cortex-M">                      <!-- defines the condition with the ID "Cortex-M" -->
    <description>True if the active device has a Cortex-M0 or Cortex-M0+ or Cortex-M3 or Cortex-M4 or SC000 or SC3000 processor </description>
    <accept Dcore="Cortex-M0"/>                  <!-- any of the following cores will make the condition resolve to true -->
    <accept Dcore="Cortex-M0+"/>
    <accept Dcore="Cortex-M23"/>
    <accept Dcore="Cortex-M3"/>
    <accept Dcore="Cortex-M33"/>

    <description>True if the component Device Startup is selected and the device has a Cortex-M processor</description>
    <require Cclass="Device" Cgroup="Startup"/>   <!-- needs a software component Device Startup AND ... -->
    <require condition="Cortex-M"/>               <!-- ... needs that condition with ID=Cortex-M to be true. -->
  </condition>
  <condition id="CMSIS-DSP">                      <!-- defines the condition with the ID "CMSIS-DSP" -->
    <description>True if CMSIS-Core == TRUE and either GCC or ARMCC and device running in little-endian byte ordering</description>
    <require condition="CMSIS-Core"/>             <!-- needs a software component Device Startup AND ... -->
    <accept Tcompiler="GCC"/>                     <!-- ... works either with the GCC compiler OR ... -->
    <accept Tcompiler="ARMCC"/>                   <!-- ... the ARMCC compiler AND ... -->
    <require Dendian="Little-endian"/>            <!-- ... requires a device running in little-endian byte ordering -->
  </condition>
  <condition id="No STM32">                       <!-- defines the condition with ID "No STM32" -->
    <description>False if the device is from ST and the device name starts with "STM32"</description>
    <deny Dvendor="STMicroelectronics:13" Dname="STM32*"/>  <!-- device name must not start with STM32 and be from vendor ST-->
  </condition>

/package/conditions

This element groups all conditions used in the Software Pack.

condition	Define the individual dependency condition.	xs:string	1..*

/package/conditions/condition

Conditions are dependency rules that can apply to elements such as a component or file. Other elements can refer to a rule using their attribute condition, which links to the attribute id of a condition. If a condition resolves to false, then the component or file description is ignored.

require¹	All require must be true to signal a true for the complete condition (AND-Rule).	FilterType	0..*
deny¹	If one deny is true the complete condition becomes false. This element overrules require and accept (AND-NOT-Rule).	FilterType	0..*

Note: 1: At least one of these elements must be present in any condition.

/package/conditions/condition/accept

/package/conditions/condition/require

/package/conditions/condition/deny

All attributes set in an accept, require, or deny must resolve to true for the element to become true. A condition becomes true when:

At least one accept element is true, AND
all require elements are true, AND
no deny element is true.

*) Wild-cards can be used to match names with the following definitions:

'*' matches any substring
'?' matches any single character
[abc] matches any character in the set (a,b,c)

**) These attributes must not be used in conditions because

'Dfamily' and 'DsubFamily' turn out to be volatile.
conditions shall only filter for selectable devices. 'Dvariant'effectively is just an alias for 'Dname'. Once a <variant> tag exists, the <device> tag no longer represents a selectable device.
