How to install an NSIS Installer?

[Xelbayria]

Hello,

This is new to me. I wasn't sure how to do this using scoop to install a software that has NSIS installer. Do anyone know how to install an NSIS installer using Scoop's feature of installing? or is it impossible?

Nullsoft Installers can be extracted via 7-Zip. See krita.json for example. (But, newer versions of NSIS require a workaround ScoopInstaller/Main#4164, qemu.json)

I was able to solved it with the examples you provided. I'll be adding that in my note! Thanks!

hi @ r15ch13 and others

at https://github.com/ScoopInstaller/Main/pull/4233/files and https://github.com/ScoopInstaller/Scoop/pull/5294/files and https://github.com/ScoopInstaller/Main/blob/74674c60be3be604a0dc83217ca67d38bf624587/bucket/qemu.json#L8-L12

            "url": "https://qemu.weilnetz.de/w64/qemu-w64-setup-20221208.exe#/dl.7z_",
    "pre_install": "Expand-7zipArchive \"$dir\\dl.7z_\" \"$dir\" -Removal -Switches '-xr!*.exe.nsis -x!$PLUGINSDIR'",

$ 7z --help | grep r[ | tail -n+3
  -i[r[-|0]]{@listfile|!wildcard} : Include filenames
  -r[-|0] : Recurse subdirectories for name search
  -x[r[-|0]]{@listfile|!wildcard} : eXclude filenames

why is it renamed to *.7z_ instead of *.7z ?
why are we not extracting *.exe.nsis and even $PLUGINSDIR?

i was trying to create manifest for eclipse-theiaIDE which is also a nullsoft installer, and attached below is its directory structure.

• see there's no *.exe.nsis file in there
• and more importantly, the $PLUGINSDIR contains $PLUGINSDIR\app-64.7z, contents of which seems to be the ones of a normal zip package
• so, if we are excluding the $PLUGINSDIR from being extracted, then how will we get app-64.7z ??

$ 7z l TheiaIDESetup.exe
