NSIS unattended options

Question

I want to build a NSIS-script, which has three section

• section Main
• section Minor
• section Shared

Shared is invisible and would be installed, if Main or Minor is checked. If I start the installer, every section (Main, Minor) is checked.

Now it should be able to define the section (in silent install). What have I to change, to only install Main or Minor or Both?

${If} $1 = 0
    ;Set defaults
    !insertmacro SelectSection ${SID_MAIN}
    !insertmacro SelectSection ${SID_MINOR}
${EndIf}

call EnforceSectionDependencies
FunctionEnd

Function EnforceSectionDependencies
!insertmacro UnselectSection ${SID_SHARED}
${If} ${SectionIsSelected} ${SID_MAIN}
${OrIf} ${SectionIsSelected} ${SID_MINOR}
    !insertmacro SelectSection ${SID_SHARED}
${EndIf}

You should look at the Section management part of the documentation, notably the SectionSetFlags to change the sections selections.

Also, maybe that the How to control Section selections, while using SubSections & InstTypes example will be useful.
