11 .. index:: single: msi
15 The :mod:`msilib` supports the creation of Microsoft Installer (``.msi``) files.
16 Because these files often contain an embedded "cabinet" file (``.cab``), it also
17 exposes an API to create CAB files. Support for reading ``.cab`` files is
18 currently not implemented; read support for the ``.msi`` database is possible.
20 This package aims to provide complete access to all tables in an ``.msi`` file,
21 therefore, it is a fairly low-level API. Two primary applications of this
22 package are the :mod:`distutils` command ``bdist_msi``, and the creation of
23 Python installer package itself (although that currently uses a different
24 version of ``msilib``).
26 The package contents can be roughly split into four parts: low-level CAB
27 routines, low-level MSI routines, higher-level MSI routines, and standard table
31 .. function:: FCICreate(cabname, files)
33 Create a new CAB file named *cabname*. *files* must be a list of tuples, each
34 containing the name of the file on disk, and the name of the file inside the CAB
37 The files are added to the CAB file in the order they appear in the list. All
38 files are added into a single CAB file, using the MSZIP compression algorithm.
40 Callbacks to Python for the various steps of MSI creation are currently not
44 .. function:: UuidCreate()
46 Return the string representation of a new unique identifier. This wraps the
47 Windows API functions :cfunc:`UuidCreate` and :cfunc:`UuidToString`.
50 .. function:: OpenDatabase(path, persist)
52 Return a new database object by calling MsiOpenDatabase. *path* is the file
53 name of the MSI file; *persist* can be one of the constants
54 ``MSIDBOPEN_CREATEDIRECT``, ``MSIDBOPEN_CREATE``, ``MSIDBOPEN_DIRECT``,
55 ``MSIDBOPEN_READONLY``, or ``MSIDBOPEN_TRANSACT``, and may include the flag
56 ``MSIDBOPEN_PATCHFILE``. See the Microsoft documentation for the meaning of
57 these flags; depending on the flags, an existing database is opened, or a new
61 .. function:: CreateRecord(count)
63 Return a new record object by calling :cfunc:`MSICreateRecord`. *count* is the
64 number of fields of the record.
67 .. function:: init_database(name, schema, ProductName, ProductCode, ProductVersion, Manufacturer)
69 Create and return a new database *name*, initialize it with *schema*, and set
70 the properties *ProductName*, *ProductCode*, *ProductVersion*, and
73 *schema* must be a module object containing ``tables`` and
74 ``_Validation_records`` attributes; typically, :mod:`msilib.schema` should be
77 The database will contain just the schema and the validation records when this
81 .. function:: add_data(database, table, records)
83 Add all *records* to the table named *table* in *database*.
85 The *table* argument must be one of the predefined tables in the MSI schema,
86 e.g. ``'Feature'``, ``'File'``, ``'Component'``, ``'Dialog'``, ``'Control'``,
89 *records* should be a list of tuples, each one containing all fields of a
90 record according to the schema of the table. For optional fields,
91 ``None`` can be passed.
93 Field values can be int or long numbers, strings, or instances of the Binary
97 .. class:: Binary(filename)
99 Represents entries in the Binary table; inserting such an object using
100 :func:`add_data` reads the file named *filename* into the table.
103 .. function:: add_tables(database, module)
105 Add all table content from *module* to *database*. *module* must contain an
106 attribute *tables* listing all tables for which content should be added, and one
107 attribute per table that has the actual content.
109 This is typically used to install the sequence tables.
112 .. function:: add_stream(database, name, path)
114 Add the file *path* into the ``_Stream`` table of *database*, with the stream
118 .. function:: gen_uuid()
120 Return a new UUID, in the format that MSI typically requires (i.e. in curly
121 braces, and with all hexdigits in upper-case).

314 All wrappers around MSI functions raise :exc:`MsiError`; the string inside the
315 exception will contain more detail.
326 The class :class:`CAB` represents a CAB file. During MSI construction, files
327 will be added simultaneously to the ``Files`` table, and to a CAB file. Then,
328 when all files have been added, the CAB file can be written, then added to the
331 *name* is the name of the CAB file in the MSI file.
334 .. method:: append(full, file, logical)
336 Add the file with the pathname *full* to the CAB file, under the name
337 *logical*. If there is already a file named *logical*, a new file name is
340 Return the index of the file in the CAB file, and the new name of the file
344 .. method:: commit(database)
346 Generate a CAB file, add it as a stream to the MSI file, put it into the
347 ``Media`` table, and remove the generated file from the disk.
356 .. class:: Directory(database, cab, basedir, physical, logical, default, component, [componentflags])
358 Create a new directory in the Directory table. There is a current component at
359 each point in time for the directory, which is either explicitly created through
360 :meth:`start_component`, or implicitly when files are added for the first time.
361 Files are added into the current component, and into the cab file. To create a
362 directory, a base directory object needs to be specified (can be ``None``), the
363 path to the physical directory, and a logical directory name. *default*
364 specifies the DefaultDir slot in the directory table. *componentflags* specifies
365 the default flags that new components get.
368 .. method:: start_component([component[, feature[, flags[, keyfile[, uuid]]]]])
370 Add an entry to the Component table, and make this component the current
371 component for this directory. If no component name is given, the directory
372 name is used. If no *feature* is given, the current feature is used. If no
373 *flags* are given, the directory's default flags are used. If no *keyfile*
374 is given, the KeyPath is left null in the Component table.
377 .. method:: add_file(file[, src[, version[, language]]])
379 Add a file to the current component of the directory, starting a new one
380 if there is no current component. By default, the file name in the source
381 and the file table will be identical. If the *src* file is specified, it
382 is interpreted relative to the current directory. Optionally, a *version*
383 and a *language* can be specified for the entry in the File table.
386 .. method:: glob(pattern[, exclude])
388 Add a list of files to the current component as specified in the glob
389 pattern. Individual files can be excluded in the *exclude* list.
392 .. method:: remove_pyc()
394 Remove ``.pyc``/``.pyo`` files on uninstall.

439 .. class:: Control(dlg, name)
441 Base class of the dialog controls. *dlg* is the dialog object the control
442 belongs to, and *name* is the control's name.
445 .. method:: event(event, argument[, condition=1[, ordering]])
447 Make an entry into the ``ControlEvent`` table for this control.
450 .. method:: mapping(event, attribute)
452 Make an entry into the ``EventMapping`` table for this control.
455 .. method:: condition(action, condition)
457 Make an entry into the ``ControlCondition`` table for this control.
460 .. class:: RadioButtonGroup(dlg, name, property)
462 Create a radio button control named *name*. *property* is the installer property
463 that gets set when a radio button is selected.
466 .. method:: add(name, x, y, width, height, text [, value])
468 Add a radio button named *name* to the group, at the coordinates *x*, *y*,
469 *width*, *height*, and with the label *text*. If *value* is omitted, it
473 .. class:: Dialog(db, name, x, y, w, h, attr, title, first, default, cancel)
475 Return a new :class:`Dialog` object. An entry in the ``Dialog`` table is made,
476 with the specified coordinates, dialog attributes, title, name of the first,
477 default, and cancel controls.
480 .. method:: control(name, type, x, y, width, height, attributes, property, text, control_next, help)
482 Return a new :class:`Control` object. An entry in the ``Control`` table is
483 made with the specified parameters.
485 This is a generic method; for specific types, specialized methods are
489 .. method:: text(name, x, y, width, height, attributes, text)
491 Add and return a ``Text`` control.
494 .. method:: bitmap(name, x, y, width, height, text)

534 :mod:`msilib` provides a few subpackages that contain only schema and table
535 definitions. Currently, these definitions are based on MSI version 2.0.
540 This is the standard MSI schema for MSI 2.0, with the *tables* variable
541 providing a list of table definitions, and *_Validation_records* providing the
542 data for MSI validation.
547 This module contains table contents for the standard sequence tables:
548 *AdminExecuteSequence*, *AdminUISequence*, *AdvtExecuteSequence*,
549 *InstallExecuteSequence*, and *InstallUISequence*.
554 This module contains definitions for the UIText and ActionText tables, for the
555 standard installer actions.
