WiXInstaller

class starlark_tugger.WiXInstaller

The WiXInstaller type represents a Windows installer built with the WiX Toolset.

WiXInstaller instances allow you to collect .wxs files for processing and to turn these into an installer using the light.exe tool in the WiX Toolset.

Files constituting your application’s install layout can be registered via methods like WiXInstaller.add_install_file() and WiXInstaller.add_install_files(). When the installer is generated, we take the registered install files and dynamically produce a .wxs file named WiXInstaller.install_files_wxs_path containing <Fragment>, <Directory>, etc entries for the install files. This produced .wxs file is automatically built. The root <DirectoryRef> in this autogenerated file refers to a <Directory> in some external .wxs file where the files should be materialized. The exact Id value to use is defined by WiXInstaller.install_files_root_directory_id. Its default value is APPLICATIONFOLDER.

What all this means is that this type takes care of materializing files registered for installation such that WiX can find them and register them for installation. All you have to do is define a .wxs defining an installer and ensure WiXInstaller.install_files_root_directory_id points to a valid <Directory Id= value.

install_files_root_directory_id

(str)

Defines the Id value for the <Directory> where install files (files added via methods like WiXInstaller.add_install_file()) should be materialized.

install_files_wxs_path

(str)

Defines the filename/path that the auto-generated .wxs file containing fragments for install files should be written to.

__init__(id: str, filename: str) → WiXInstaller

WiXInstaller() is called to construct a new instance. It accepts the following arguments:

id

The name of the installer being built.

This value is used in Id attributes in WiX XML files and must conform to limitations imposed by WiX. Notably, this must be alphanumeric and - cannot be used.

This value is also used to derive GUIDs for the installer.

This value should reflect the name of the entity being installed and should be unique to prevent collisions with other installers.

filename

The name of the file that will be built.

WiX supports generating multiple installer file types depending on the content of the .wxs files. You will have to provide a filename that is appropriate for the installer type.

File extensions of .msi and .exe are common. If using add_simple_installer(), you will want to provide an .msi filename.

add_build_files(manifest: FileManifest)

This method registers additional files to make available to the build environment. Files will be materialized next to .wxs files that will be processed as part of building the installer.

Accepted arguments are:

manifest
The file manifest defining additional files to install.
add_build_file(build_path: str, filesystem_path: str, force_read: Optional[bool] = False)

This method registers a single additional file to make available to the build environment.

Accepted arguments are:

build_path
The relative path to materialize inside the build environment
filesystem_path
The filesystem path of the file to copy into the build environment.
force_read
Whether to read the content of this file into memory when this function is called.
add_install_file(install_path: str, filesystem_path: str, force_read: Optional[bool] = False)

Add a file from the filesystem to be installed by the installer.

This methods accepts the following arguments:

install_path
The relative path to materialize inside the installation directory.
filesystem_path
The filesystem path of the file to install.
force_read
Whether to read the content of this file into memory when this function is called.

As a file is added, it is checked for code signing compatibility with the action windows-installer-file-added.

add_install_files(manifest: FileManifest)

Add files defined in a FileManifest to be installed by the installer.

This method accepts the following arguments:

manifest
Defines files to materialize in the installation directory. All these files will be installed by the installer.

As files are added, they are checked for code signing compatibility with the action windows-installer-file-added.

add_msi_builder(builder: WiXMSIBuilder)

This method adds a WiXMSIBuilder instance to this instance, marking it for processing/building.

add_simple_installer(product_name: str, product_version: str, product_manufacturer: str, program_files: FileManifest)

This method will populate the installer configuration with a pre-defined and simple/basic configuration suitable for simple applications. This method effectively derives a .wxs which will produce an MSI that materializes files in the Program Files directory.

Accepted arguments are:

product_name
The name of the installed product. This becomes the value of the <Product Name="..."> attribute in the generated .wxs file.
product_version
The version string of the installed product. This becomes the value of the <Product Version="..."> attribute in the generated .wxs file.
product_manufacturer
The author of the product. This becomes the value of the <Product Manufacturer="..."> attribute in the generated .wxs file.
program_files
Files to materialize in the Program Files/<product_name> directory upon install.
add_wxs_file(path: str, preprocessor_parameters: Optional[dict[str, str]])

Adds an existing .wxs file to be processed as part of building this installer.

Accepted arguments are:

path
The filesystem path to the .wxs file to add. The file will be copied into a temporary directory as part of building the installer and the destination filename will be the same as the file’s name.
preprocessor_parameters
Preprocessor parameters to define when invoking candle.exe for this .wxs file. These effectively constitute -p arguments to candle.exe.
set_variable(key: str, value: Optional[str])

Defines a variable to be passed to light.exe as -d arguments.

Accepted arguments are:

key
The name of the variable.
value
The value of the variable. If None is used, the variable has no value and is simply defined.
build(target: str) → ResolvedTarget

This method will build the installer using the WiX Toolset.

This method accepts the following arguments:

target
The name of the target being built.

Upon successful generation of an installer, the produced installer will be assessed for code signing with the windows-installer-creation action.
