A `Param` instance can be used to describe an argument or option that a command takes, or an attribute that a command returns. The `Param` base class is not used directly, but there are many subclasses for specific Python data types (like `Str` or `Int`) and specific properties (like `Password`). To create a `Param` instance, you must always provide the parameter *name*, which should be the LDAP attribute name if the parameter describes the attribute of an LDAP entry. For example, we could create an `Str` instance describing the user's last-name attribute like this: >>> from ipalib import Str >>> sn = Str('sn') >>> sn.name 'sn' When creating a `Param`, there are also a number of optional kwargs which which can provide additional meta-data and functionality. For example, every parameter has a *cli_name*, the name used on the command-line-interface. By default the *cli_name* is the same as the *name*: >>> sn.cli_name 'sn' But often the LDAP attribute name isn't user friendly for the command-line, so you can override this with the *cli_name* kwarg: >>> sn = Str('sn', cli_name='last') >>> sn.name 'sn' >>> sn.cli_name 'last' Note that the RPC interfaces (and the internal processing pipeline) always use the parameter *name*, regardless of what the *cli_name* might be. A `Param` also has two translatable kwargs: *label* and *doc*. These must both be `Gettext` instances. They both default to a place-holder `FixMe` instance, a subclass of `Gettext` used to mark a missing translatable string: >>> sn.label FixMe('sn') >>> sn.doc FixMe('sn') The *label* is a short phrase describing the parameter. It's used on the CLI when interactively prompting for values, and as a label for form inputs in the web-UI. The *label* should start with an initial capital. For example: >>> from ipalib import _ >>> sn = Str('sn', ... cli_name='last', ... label=_('Last name'), ... ) >>> sn.label Gettext('Last name', domain='ipa', localedir=None) The *doc* is a longer description of the parameter. It's used on the CLI when displaying the help information for a command, and as extra instruction for a form input on the web-UI. By default the *doc* is the same as the *label*: >>> sn.doc Gettext('Last name', domain='ipa', localedir=None) But you can override this with the *doc* kwarg. Like the *label*, the *doc* should also start with an initial capital and should not end with any punctuation. For example: >>> sn = Str('sn', ... cli_name='last', ... label=_('Last name'), ... doc=_("The user's last name"), ... ) >>> sn.doc Gettext("The user's last name", domain='ipa', localedir=None) Demonstration aside, you should always provide at least the *label* so the various UIs are translatable. Only provide the *doc* if the parameter needs a more detailed description for clarity. iN(tMAXINTtMININT(tx509(t_(t check_name(tReadOnlytlock(tConversionErrortRequirementErrortValidationError(tPasswordMismatchtBase64DecodeErrortCertificateFormatErrortCertificateOperationError(t TYPE_ERRORtCALLABLE_ERRORtLDAP_GENERALIZED_TIME_FORMAT(tGettexttFixMe(tjson_serializetvalidate_idna_domain(tload_der_x509_certificatetIPACertificatetdefault_backend(tstrip_csr_headertapirepr(tkerberos(tDN(tDNSNamecCs5|r tSt|tjttjfr-tStSdS(N(tFalset isinstancetsixt integer_typestfloattdecimaltDecimaltTrue(tvalue((s5/usr/lib/python2.7/site-packages/ipalib/parameters.pyt_is_nulls t DefaultFromcBs2eZdZdZdZdZdZRS(s Derive a default value from other supplied values. For example, say you wanted to create a default for the user's login from the user's first and last names. It could be implemented like this: >>> login = DefaultFrom(lambda first, last: first[0] + last) >>> login(first='John', last='Doe') 'JDoe' If you do not explicitly provide keys when you create a `DefaultFrom` instance, the keys are implicitly derived from your callback by inspecting ``callback.func_code.co_varnames``. The keys are available through the ``DefaultFrom.keys`` instance attribute, like this: >>> login.keys ('first', 'last') The callback is available through the ``DefaultFrom.callback`` instance attribute, like this: >>> login.callback # doctest:+ELLIPSIS at 0x...> >>> login.callback.func_code.co_varnames # The keys ('first', 'last') The keys can be explicitly provided as optional positional arguments after the callback. For example, this is equivalent to the ``login`` instance above: >>> login2 = DefaultFrom(lambda a, b: a[0] + b, 'first', 'last') >>> login2.keys ('first', 'last') >>> login2.callback.func_code.co_varnames # Not the keys ('a', 'b') >>> login2(first='John', last='Doe') 'JDoe' If any keys are missing when calling your `DefaultFrom` instance, your callback is not called and ``None`` is returned. For example: >>> login(first='John', lastname='Doe') is None True >>> login() is None True Any additional keys are simply ignored, like this: >>> login(last='Doe', first='John', middle='Whatever') 'JDoe' As above, because `DefaultFrom.__call__` takes only pure keyword arguments, they can be supplied in any order. Of course, the callback need not be a ``lambda`` expression. This third example is equivalent to both the ``login`` and ``login2`` instances above: >>> def get_login(first, last): ... return first[0] + last ... >>> login3 = DefaultFrom(get_login) >>> login3.keys ('first', 'last') >>> login3.callback.func_code.co_varnames ('first', 'last') >>> login3(first='John', last='Doe') 'JDoe' cGst|s.ttd|t|fn||_t|dkr|j}|jd@rntdn|j |j |_ n ||_ xH|j D]=}t|t k rtt dt |t|fqqWt|dS(s :param callback: The callable to call when all keys are present. :param keys: Optional keys used for source values. tcallbackii s3callback: variable-length argument list not allowedtkeysN(tcallablet TypeErrorRttypeR(tlent__code__tco_flagst ValueErrort co_varnamest co_argcountR)tstrRR(tselfR(R)tfctkey((s5/usr/lib/python2.7/site-packages/ipalib/parameters.pyt__init__s     &cCs6td|jD}d|jjdj|fS(Ncss|]}t|VqdS(N(trepr(t.0tk((s5/usr/lib/python2.7/site-packages/ipalib/parameters.pys ss%s(%s)s, (ttupleR)t __class__t__name__tjoin(R4targs((s5/usr/lib/python2.7/site-packages/ipalib/parameters.pyt__repr__s c sXtfd|jD}d|kr/dSy|j|SWntk rSnXdS(s Call the callback if all keys are present.

Param attributes: ================= The behavior of Param class and subclasses can be controlled using the following set of attributes: - cli_name: option name in CLI - cli_short_name: one character version of cli_name - deprecated_cli_aliases: deprecated CLI aliases - label: very short description of the parameter. This value is used in when the Command output is printed to CLI or in a Command help - doc: parameter long description used in help - required: the parameter is marked as required for given Command - multivalue: indicates if the attribute is multivalued - primary_key: Command's parameter primary key is used for unique identification of an LDAP object and for sorting - normalizer: a custom function for Param value normalization - default_from: a custom function for generating default values of parameter instance - autofill: by default, only `required` parameters get a default value from the default_from function. When autofill is enabled, optional attributes get the default value filled too - query: this attribute is controlled by framework. When the `query` is enabled, framework assumes that the value is only queried and not inserted in the LDAP. Validation is then relaxed - custom parameter validators are skipped and only basic class validators are executed to check the parameter value - attribute: this attribute is controlled by framework and enabled for all LDAP objects parameters (unless parameter has "virtual_attribute" flag). All parameters with enabled `attribute` are being encoded and placed to an entry passed to LDAP Create/Update calls - include: a list of contexts where this parameter should be included. `Param.use_in_context()` provides further information. - exclude: a list of contexts where this parameter should be excluded. `Param.use_in_context()` provides further information. - flags: there are several flags that can be used to further tune the parameter behavior: * no_display (Output parameters only): do not display the parameter * no_create: do not include the parameter for crud.Create based commands * no_update: do not include the parameter for crud.Update based commands * no_search: do not include the parameter for crud.Search based commands * no_option: this attribute is not displayed in the CLI, usually because there's a better way of setting it (for example, a separate command) * virtual_attribute: the parameter is not stored physically in the LDAP and thus attribute `attribute` is not enabled * suppress_empty (Output parameters only): do not display parameter value when empty * ask_create: CLI asks for parameter value even when the parameter is not `required`. Applied for all crud.Create based commands * ask_update: CLI asks for parameter value even when the parameter is not `required`. Applied for all crud.Update based commands * req_update: The parameter is `required` in all crud.Update based commands * nonempty: This is an internal flag; a required attribute should be used instead of it. The value of this parameter must not be empty, but it may not be given at all. All crud.Update commands automatically convert required parameters to `nonempty` ones, so the value can be unspecified (unchanged) but cannot be deleted. * optional_create: do not require the parameter for crud.Create based commands * allow_mod_for_managed_permission: permission-mod allows changing the parameter for managed permissions - hint: this attribute is currently not used - alwaysask: when enabled, CLI asks for parameter value even when the parameter is not `required` - sortorder: used to sort a list of parameters for Command.

This function allows you to create `Str` parameters (the most common) from a convenient shorthand that defines the parameter name, whether it is required, and whether it is multivalue. (For the definition of the shorthand syntax, see the `parse_param_spec()` function.) If ``spec`` is an ``str`` instance, it will be used to create a new `Str` parameter, which will be returned. For example: >>> s = create_param('hometown?') >>> s Str('hometown?') >>> (s.name, s.required, s.multivalue) ('hometown', False, False) On the other hand, if ``spec`` is already a `Param` instance, it is returned unchanged. For example: >>> b = Bytes('cert') >>> create_param(b) is b True As a plugin author, you will not call this function directly (which would be no more convenient than simply creating the `Str` instance). Instead, `frontend.Command` will call it for you when it evaluates the ``takes_args`` and ``takes_options`` attributes, and `frontend.Object` will call it for you when it evaluates the ``takes_params`` attribute. :param spec: A spec string or a `Param` instance.
