setup-nsis

Set up NSIS in your GitHub workflow.

Usage

- uses: nsis-dev/setup-nsis@v1
- run: makensis installer.nsi

With build options:

- uses: nsis-dev/setup-nsis@v1
  with:
    version: "latest"
    large-strings: false
    advanced-logging: false

Inputs

Name	Default	Description
version	latest	NSIS version, e.g. 3.12. latest resolves via SourceForge.
large-strings	false	NSIS_MAX_STRLEN=8192.
advanced-logging	false	NSIS_CONFIG_LOG=yes.

Note

On Windows, large-strings and advanced-logging cannot be combined: the action uses upstream's prebuilt special builds and there is no build that ships both. Enabling both fails the step.

Outputs

Name	Description
version	Resolved NSIS version.
nsisdir	NSIS installation directory (also exported as NSISDIR).

On Linux and macOS, NSIS is built from source; on Windows the action installs upstream's prebuilt binaries. Either way the result is cached per OS, version and option combination, so only the first run pays the setup cost.
