\modulesynopsis{Creation of Microsoft Installer files, and CAB files.}

\index{msi}
\versionadded{2.5}
The \module{msilib} supports the creation of Microsoft Installer
(\code{.msi}) files. Because these files often contain an embedded
``cabinet'' file (\code{.cab}), it also exposes an API to create
CAB files. Support for reading \code{.cab} files is currently not
implemented; read support for the \code{.msi} database is possible.
This package aims to provide complete access to all tables in an
\code{.msi} file, therefore, it is a fairly low-level API. Two
primary applications of this package are the \module{distutils}
command \code{bdist_msi}, and the creation of Python installer
package itself (although that currently uses a different version
of \code{msilib}).
The package contents can be roughly split into four parts:
low-level CAB routines, low-level MSI routines, higher-level
MSI routines, and standard table structures.
\begin{funcdesc}{FCICreate}{cabname, files}
Create a new CAB file named \var{cabname}. \var{files} must
be a list of tuples, each containing the name of the file on
disk, and the name of the file inside the CAB file.
The files are added to the CAB file in the order they have
in the list. All files are added into a single CAB file,
using the MSZIP compression algorithm.
Callbacks to Python for the various steps of MSI creation
are currently not exposed.
\end{funcdesc}
\begin{funcdesc}{UUIDCreate}{}
Return the string representation of a new unique identifier.
This wraps the Windows API functions \code{UuidCreate} and
\code{UuidToString}.
\end{funcdesc}
\begin{funcdesc}{OpenDatabase}{path, persist}
Return a new database object by calling MsiOpenDatabase.
\var{path} is the file name of the
MSI file; persist can be one of the constants
\code{MSIDBOPEN_CREATEDIRECT}, \code{MSIDBOPEN_CREATE},
\code{MSIDBOPEN_DIRECT}, \code{MSIDBOPEN_READONLY}, or
\code{MSIDBOPEN_TRANSACT}, and may include the flag
\code{MSIDBOPEN_PATCHFILE}. See the Microsoft documentation for
the meaning of these flags; depending on the flags,
an existing database is opened, or a new one created.
\end{funcdesc}
\begin{funcdesc}{CreateRecord}{count}
Return a new record object by calling MSICreateRecord.
\var{count} is the number of fields of the record.
\end{funcdesc}
\begin{funcdesc}{init_database}{name, schema, ProductName, ProductCode, ProductVersion, Manufacturer}
Create and return a new database \var{name}, initialize it
with \var{schema}, and set the properties \var{ProductName},
\var{ProductCode}, \var{ProductVersion}, and \var{Manufacturer}.
\var{schema} must be a module object containing \code{tables} and
\code{_Validation_records} attributes; typically,
\module{msilib.schema} should be used.
The database will contain just the schema and the validation
records when this function returns.
\end{funcdesc}
\begin{funcdesc}{add_data}{database, records}
Add all \var{records} to \var{database}. \var{records} should
be a list of tuples, each one containing all fields of a record
according to the schema of the table. For optional fields,
\code{None} can be passed.
Field values can be int or long numbers, strings, or instances
of the Binary class.
\end{funcdesc}
\begin{classdesc}{Binary}{filename}
Represents entries into the Binary table; inserting such
an object using \function{add_data} reads the file named
\var{filename} into the table.
\end{classdesc}
\begin{funcdesc}{add_tables}{database, module}
Add all table content from \var{module} to \var{database}.
\var{module} must contain an attribute \var{tables}
listing all tables for which content should be added,
and one attribute per table that has the actual content.
This is typically used to install the sequence
\end{funcdesc}
\begin{funcdesc}{add_stream}{database, name, path}
Add the file \var{path} into the \code{_Stream} table
of \var{database}, with the stream name \var{name}.
\end{funcdesc}
\begin{funcdesc}{gen_uuid}{}
Return a new UUID, in the format that MSI typically
requires (i.e. in curly braces, and with all hexdigits
in upper-case).
\end{funcdesc}

\subsection{Errors\label{msi-errors}}
All wrappers around MSI functions raise \exception{MsiError};
the string inside the exception will contain more detail.
\subsection{CAB Objects\label{cab}}
\begin{classdesc}{CAB}{name}
The class \class{CAB} represents a CAB file. During MSI construction,
files will be added simultaneously to the \code{Files} table, and
to a CAB file. Then, when all files have been added, the CAB file
can be written, then added to the MSI file.
\var{name} is the name of the CAB file in the MSI file.
\end{classdesc}
\begin{methoddesc}[CAB]{append}{full, logical}
Add the file with the pathname \var{full} to the CAB file,
under the name \var{logical}. If there is already a file
named \var{logical}, a new file name is created.
Return the index of the file in the CAB file, and the
new name of the file inside the CAB file.
\end{methoddesc}
\begin{methoddesc}[CAB]{append}{database}
Generate a CAB file, add it as a stream to the MSI file,
put it into the \code{Media} table, and remove the generated
file from the disk.
\end{methoddesc}
\subsection{Directory Objects\label{msi-directory}}
\begin{classdesc}{Directory}{database, cab, basedir, physical,
logical, default, component, \optional{flags}}
Create a new directory in the Directory table. There is a current
component at each point in time for the directory, which is either
explicitly created through start_component, or implicitly when files
are added for the first time. Files are added into the current
component, and into the cab file. To create a directory, a base
directory object needs to be specified (can be None), the path to
the physical directory, and a logical directory name. Default
specifies the DefaultDir slot in the directory table. componentflags
specifies the default flags that new components get.
\end{classdesc}
\begin{methoddesc}[Directory]{start_component}{\optional{component\optional{,
feature\optional{, flags\optional{, keyfile\optional{, uuid}}}}}}
Add an entry to the Component table, and make this component the
current for this directory. If no component name is given, the
directory name is used. If no feature is given, the current feature
is used. If no flags are given, the directory's default flags are
used. If no keyfile is given, the KeyPath is left null in the
Component table.
\end{methoddesc}
\begin{methoddesc}[Directory]{add_file}{file\optional{, src\optional{,
version\optional{, language}}}}
Add a file to the current component of the directory, starting a new
one one if there is no current component. By default, the file name
in the source and the file table will be identical. If the src file
is specified, it is interpreted relative to the current
directory. Optionally, a version and a language can be specified for
the entry in the File table.
\end{methoddesc}
\begin{methoddesc}[Directory]{glob}{pattern\optional{, exclude}}
Add a list of files to the current component as specified in the glob
pattern. Individual files can be excluded in the exclude list.
\end{methoddesc}
\begin{methoddesc}[Directory]{remove_pyc}{}
Remove .pyc/.pyo files on uninstall
\end{methoddesc}

\subsection{Features\label{features}}
\begin{classdesc}{Feature}{database, id, title, desc, display\optional{,
level=1\optional{, parent\optional\{, directory\optional{,
attributes=0}}}}
Add a new record to the \code{Feature} table, using the values
\var{id}, \var{parent.id}, \var{title}, \var{desc}, \var{display},
\var{level}, \var{directory}, and \var{attributes}. The resulting
feature object can be passed to the \method{start_component} method
of \class{Directory}.
\end{classdesc}
\begin{methoddesc}[Feature]{set_current}{}
Make this feature the current feature of \module{msilib}.
New components are automatically added to the default feature,
unless a feature is explicitly specified.
\end{methoddesc}

\subsection{GUI classes\label{msi-gui}}
\module{msilib} provides several classes that wrap the GUI tables in
an MSI database. However, no standard user interface is provided; use
\module{bdist_msi} to create MSI files with a user-interface for
installing Python packages.
\begin{classdesc}{Control}{dlg, name}
Base class of the dialog controls. \var{dlg} is the dialog object
the control belongs to, and \var{name} is the control's name.
\end{classdesc}

condition = ``1''\optional{, ordering}}}
Make an entry into the \code{ControlEvent} table for this control.
\end{methoddesc}
\begin{methoddesc}[Control]{mapping}{event, attribute}
Make an entry into the \code{EventMapping} table for this control.
\end{methoddesc}
\begin{methoddesc}[Control]{condition}{action, condition}
Make an entry into the \code{ControlCondition} table for this control.

\optional{, value}}
Add a radio button named \var{name} to the group, at the
coordinates \var{x}, \var{y}, \var{width}, \var{height}, and
with the label \var{text}. If \var{value} is omitted, it
defaults to \var{name}.
\end{methoddesc}
\begin{classdesc}{Dialog}{db, name, x, y, w, h, attr, title, first,
default, cancel}

\module{msilib} provides a few subpackages that contain
only schema and table definitions. Currently, these definitions
are based on MSI version 2.0.
\begin{datadesc}{schema}
This is the standard MSI schema for MSI 2.0, with the
\var{tables} variable providing a list of table definitions,
and \var{_Validation_records} providing the data for
MSI validation.
\end{datadesc}
\begin{datadesc}{sequence}
This module contains table contents for the standard sequence
tables: \var{AdminExecuteSequence}, \var{AdminUISequence},
\var{AdvtExecuteSequence}, \var{InstallExecuteSequence}, and
\var{InstallUISequence}.
\end{datadesc}
\begin{datadesc}{text}
This module contains definitions for the UIText and ActionText
tables, for the standard installer actions.
\end{datadesc}
