[electron-builder-nsis How Can I Use If-Else To Control MUI_PAGE_DIRECTORY?
When using Electron Builder with NSIS (Nullsoft Scriptable Install System) to create an installer for your Electron application, you can use if-else conditions to control the MUI_PAGE_DIRECTORY
based on certain conditions. Here's an example of how you can achieve this:
nsis!include MUI2.nsh
; Default directory page
!define MUI_PAGE_CUSTOMFUNCTION_PRE DirectoryPagePre
!insertmacro MUI_PAGE_DIRECTORY
Function DirectoryPagePre
${If} $SomeCondition
; Use custom directory page
nsDialogs::Create 1018
Pop $0
${NSD_CreateText} 0 0 100% 12u "Custom Directory Page"
Pop $1
nsDialogs::Show
${NSD_GetText} $1 $R0
StrCpy $INSTDIR $R0
${Else}
; Use default directory page
${EndIf}
FunctionEnd
Section
; Install files and perform other tasks
SectionEnd
; Rest of the script
In the above example, we define a custom function DirectoryPagePre
that gets executed before the directory page is shown. Inside this function, we can use an if-else condition to determine whether to use a custom directory page or the default directory page.
If the condition $SomeCondition
is true, we create a custom directory page using nsDialogs
macros. In this example, a simple text input field is displayed using ${NSD_CreateText}
. The value entered by the user is stored in $R0
, and we set the installation directory ($INSTDIR
) to the value entered by the user.
If the condition is false, the default directory page is used.
The rest of the NSIS script can include additional sections, components, and tasks as required.
Make sure to replace $SomeCondition
with your own condition that determines whether to use the custom directory page. You can use variables, functions, or other logic to define this condition.
By using if-else conditions in the DirectoryPagePre
function, you can control the behavior of the MUI_PAGE_DIRECTORY
page in your Electron Builder NSIS installer based on your specific requirements.
