New page

{{PageAuthor|Afrow UK}}

== Description ==
Macro's that are inserted in a block by block basis to build a list of Sections that are dependent on another Section. By this we mean that 1 or more Sections must have 1 or more other Sections checked first.

== Usage ==
<highlight-nsis>!insertmacro SectionDependencyVars $Var1 $Var2</highlight-nsis>
Specifies which temporary variables to use within the macros.

<highlight-nsis>!insertmacro SectionDependency SectionID</highlight-nsis>
(Required) Specifies that the Section SectionID should have a dependency on another Section.

<highlight-nsis>!insertmacro SectionDependentUpon_Begin</highlight-nsis>
(Required) Begins the list of Sections for other Sections to be dependent upon.

<highlight-nsis>!insertmacro SectionDependentUpon SectionID</highlight-nsis>
(Required) Adds the Section SectionID to the list of Sections for other Sections to be dependent on.

<highlight-nsis>!insertmacro SectionDependentUpon_End</highlight-nsis>
(Required) Ends the list.

== Example ==
This is a complete working example script which can be compiled once you have saved the actual NSH source code (further down this page).
