NSIS Completions & Snippets

The MIT License Package Control GitHub release Travis Gitter

Sublime Text completions for Nullsoft Scriptable Install System (NSIS) supporting commands, macros and plugins that are bundled with NSIS v2.46 (or higher). Also included are snippets for scaffolding different types of empty scripts and to insert code blocks. You can extend these completions for third-party plug-ins using the add-ons pack.

Windows Installer

This package is part of sublime-nsis-ide, a collection of packages that turn Sublime Text into a powerful editor for NSIS developers.

Using Git

  1. Change to your Sublime Text Packages directory
  2. Clone repository git clone 'NSIS Completions & Snippets'

Manual installation

  1. Download the latest ZIP file
  2. Unzip the archive to your Sublime Text Packages directory



When not specifying a flag alongside a command, completion will display all available flags, with the first flag always being the default.

Scaffolding snippets

Scaffolding snippets start with the prefix scaffold followed by the type of script you'd like to build:

  • Basic Script
  • InstallOptions Script
  • MUI2 Script
  • nsDialogs Script
  • nsDialogs MUI2 Script
  • NSIS Language File
  • Translate MUI2 (English, French, or Spanish)
  • Library

Several of the above snippets can set the number of sections in a script or add an init function.


With Sublime Text's fuzzy search in mind, you could for instance type scaffBasic to trigger the scaffold:Basic Script snippet and create the following script:

; Settings ---------------------------------
Name "installer_name"
OutFile "installer_name.exe"
RequestExecutionLevel user
InstallDir "$PROGRAMFILES\installer_name"

; Pages ------------------------------------
Page components
Page directory
Page instfiles

; Sections ---------------------------------
Section "section_name" section_index

    # your code here


; Functions --------------------------------

Use Tab to jump to the next relevant bit of code you might want to change, Shift-Tab to jump back.

Code snippets

Code snippets start with the prefix do followed by the code block you'd like to insert to your script:

  • help dialog
  • illegal file characters define
  • language dialog
  • message boxes
  • UAC init macro
  • version information
  • version compare
  • IsWin, IsRunningX64, and IsServer checks


To quickly add a message box with three buttons labeled "Yes", "No" and "Cancel", you could type something like doync to trigger thedo:MB_YESNOCANCEL snippet. This will insert the following line to the current position:

MessageBox MB_YESNOCANCEL "messagebox_text"

Use Tab to jump between the segments of the code.

To insert a code block of version information commands, you could type doinf to trigger the do:Version Information snippet. This will insert several lines of code:

VIProductVersion ""
VIFileVersion    ""
VIAddVersionKey  "FileDescription"  "description"
VIAddVersionKey  "FileVersion"      ""
VIAddVersionKey  "ProductName"      "product_name"
VIAddVersionKey  "ProductVersion"   ""
VIAddVersionKey  "LegalCopyright"   "copyright"
VIAddVersionKey  "OriginalFilename" "file_name.exe"
VIAddVersionKey  "Comments"         "comment"
VIAddVersionKey  "LegalTrademarks"  "trademark"
VIAddVersionKey  "CompanyName"      "company_name"
VIAddVersionKey  "InternalName"     "internal_name"
VIAddVersionKey  "PrivateBuild"     "private_build"
VIAddVersionKey  "SpecialBuild"     "special_build"

Again, you can use Tab to jump back and forth.
