12 .. index:: single: msi
16 The :mod:`msilib` supports the creation of Microsoft Installer (``.msi``) files.
17 Because these files often contain an embedded "cabinet" file (``.cab``), it also
18 exposes an API to create CAB files. Support for reading ``.cab`` files is
19 currently not implemented; read support for the ``.msi`` database is possible.
21 This package aims to provide complete access to all tables in an ``.msi`` file,
22 therefore, it is a fairly low-level API. Two primary applications of this
23 package are the :mod:`distutils` command ``bdist_msi``, and the creation of
24 Python installer package itself (although that currently uses a different
25 version of ``msilib``).
27 The package contents can be roughly split into four parts: low-level CAB
28 routines, low-level MSI routines, higher-level MSI routines, and standard table
32 .. function:: FCICreate(cabname, files)
34 Create a new CAB file named *cabname*. *files* must be a list of tuples, each
35 containing the name of the file on disk, and the name of the file inside the CAB
38 The files are added to the CAB file in the order they appear in the list. All
39 files are added into a single CAB file, using the MSZIP compression algorithm.
41 Callbacks to Python for the various steps of MSI creation are currently not
45 .. function:: UuidCreate()
47 Return the string representation of a new unique identifier. This wraps the
48 Windows API functions :cfunc:`UuidCreate` and :cfunc:`UuidToString`.
51 .. function:: OpenDatabase(path, persist)
53 Return a new database object by calling MsiOpenDatabase. *path* is the file
54 name of the MSI file; *persist* can be one of the constants
55 ``MSIDBOPEN_CREATEDIRECT``, ``MSIDBOPEN_CREATE``, ``MSIDBOPEN_DIRECT``,
56 ``MSIDBOPEN_READONLY``, or ``MSIDBOPEN_TRANSACT``, and may include the flag
57 ``MSIDBOPEN_PATCHFILE``. See the Microsoft documentation for the meaning of
58 these flags; depending on the flags, an existing database is opened, or a new
62 .. function:: CreateRecord(count)
64 Return a new record object by calling :cfunc:`MSICreateRecord`. *count* is the
65 number of fields of the record.
68 .. function:: init_database(name, schema, ProductName, ProductCode, ProductVersion, Manufacturer)
70 Create and return a new database *name*, initialize it with *schema*, and set
71 the properties *ProductName*, *ProductCode*, *ProductVersion*, and
74 *schema* must be a module object containing ``tables`` and
75 ``_Validation_records`` attributes; typically, :mod:`msilib.schema` should be
78 The database will contain just the schema and the validation records when this
82 .. function:: add_data(database, records)
84 Add all *records* to *database*. *records* should be a list of tuples, each one
85 containing all fields of a record according to the schema of the table. For
86 optional fields, ``None`` can be passed.
88 Field values can be int or long numbers, strings, or instances of the Binary
92 .. class:: Binary(filename)
94 Represents entries in the Binary table; inserting such an object using
95 :func:`add_data` reads the file named *filename* into the table.
98 .. function:: add_tables(database, module)
100 Add all table content from *module* to *database*. *module* must contain an
101 attribute *tables* listing all tables for which content should be added, and one
102 attribute per table that has the actual content.
104 This is typically used to install the sequence tables.
107 .. function:: add_stream(database, name, path)
109 Add the file *path* into the ``_Stream`` table of *database*, with the stream
113 .. function:: gen_uuid()
115 Return a new UUID, in the format that MSI typically requires (i.e. in curly
116 braces, and with all hexdigits in upper-case).

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

392 .. class:: Feature(database, id, title, desc, display[, level=1[, parent[, directory[, attributes=0]]]])
394 Add a new record to the ``Feature`` table, using the values *id*, *parent.id*,
395 *title*, *desc*, *display*, *level*, *directory*, and *attributes*. The
396 resulting feature object can be passed to the :meth:`start_component` method of
400 .. method:: Feature.set_current()
402 Make this feature the current feature of :mod:`msilib`. New components are
403 automatically added to the default feature, unless a feature is explicitly

429 Make an entry into the ``ControlEvent`` table for this control.
432 .. method:: Control.mapping(event, attribute)
434 Make an entry into the ``EventMapping`` table for this control.
437 .. method:: Control.condition(action, condition)
439 Make an entry into the ``ControlCondition`` table for this control.
442 .. class:: RadioButtonGroup(dlg, name, property)
444 Create a radio button control named *name*. *property* is the installer property
445 that gets set when a radio button is selected.
448 .. method:: RadioButtonGroup.add(name, x, y, width, height, text [, value])
450 Add a radio button named *name* to the group, at the coordinates *x*, *y*,
451 *width*, *height*, and with the label *text*. If *value* is omitted, it defaults
455 .. class:: Dialog(db, name, x, y, w, h, attr, title, first, default, cancel)
457 Return a new :class:`Dialog` object. An entry in the ``Dialog`` table is made,
458 with the specified coordinates, dialog attributes, title, name of the first,
459 default, and cancel controls.
462 .. method:: Dialog.control(name, type, x, y, width, height, attributes, property, text, control_next, help)
464 Return a new :class:`Control` object. An entry in the ``Control`` table is made
465 with the specified parameters.
467 This is a generic method; for specific types, specialized methods are provided.
470 .. method:: Dialog.text(name, x, y, width, height, attributes, text)
472 Add and return a ``Text`` control.

515 :mod:`msilib` provides a few subpackages that contain only schema and table
516 definitions. Currently, these definitions are based on MSI version 2.0.
521 This is the standard MSI schema for MSI 2.0, with the *tables* variable
522 providing a list of table definitions, and *_Validation_records* providing the
523 data for MSI validation.
528 This module contains table contents for the standard sequence tables:
529 *AdminExecuteSequence*, *AdminUISequence*, *AdvtExecuteSequence*,
530 *InstallExecuteSequence*, and *InstallUISequence*.
535 This module contains definitions for the UIText and ActionText tables, for the
536 standard installer actions.
