Get the central desktop object 4. Declare the ServiceManager 5. Get the central desktop object 6. Access the current writer document 7. Access the document's text property 8. UnoTools allows you to interact with OpenOffice. In Python 3. Confirm Python interpreter version included in LibreOffice. Writer inherits XTextRange interface and has those methods. Mar 21, Jun 7, May 6, May 5, Where does that come from? It has been replaced by pip.

Python2 is no longer to be used for any project, so please follow the instructions in Braiam's answer above. Sign up or log in Sign up using Google. Sign up using Facebook.

Featured on Meta. New post summary designs on greatest hits now, everywhere else eventually. Later modification of the struct instance does not influence the callee anymore. However, simply assigning a struct to another local variable does not create a copy, but simply creates an alias to the original instance.

PropertyValue" struct. If the UNO object is implemented in python, you possibly modify the callee's value. Don't do this! A python list is not! It has a string member named value , which holds the data of the byte sequence.

As the bytesequence most often is a container for binary data, this class allows to handle binaries efficiently. This also embeds pyuno nicely into python, as python keeps binary data in strings. However, there are certain circumstances, where a python programmer may want to pass a concrete typed value to a callee note, this is only possible for 'bridged' calls, you can't pass a typed any to another python uno object.

You can create a uno. Any by passing the type as typename or as uno. Type and the value. Any "[]short", 4,5 These anys can only be used in conjunction with the uno.

When obj is a local python object, it gets simply the 4,5 as it would have got it with the normal call. NOTE: There is currently a bug in pyuno see i , which does not let you fill anys into structs e.

Invocation", ctx self. Instances of a python class may then be passed as argument to UNO calls where anys or concrete interfaces are specified. The getTypes function defines, which interfaces are implemented by the class. To make this easier, there exists a unohelper. Base class, where a python UNO object should derive from. You can then implement a UNO interface simply by deriving from the wanted interfaces.

The following example implements a com. XOutputStream, which stores all data written into the stream within a ByteSequence. Note that this is quite a poor implementation, which is just for demonstration purposes. ByteSequence "" self. Base implementation correctly implements the XTypeProvider interface.

It allows to create instances of python classes not just within the python process but in every arbitrary UNO process including OpenOffice. The python loader loads the python runtime on demand if it is not already loaded and executes python code within the root python interpreter. If the reader is unfamiliar with the component registration process, it should visit the OpenOffice. The python loader currently supports the following protocols for incoming urls : Protocol name Description vnd.

Example: vnd. Note that you must not use the. The given module is added to the sys. The module is not added to sys. The following sample code makes a uno component out of the above UNO object note that the component is not useful, because there is no UNO method to retrieve the tuple nor does a com. OutputStream service specification exist, it's just here as an example. ImplementationHelper class TupleOutputStream unohelper. Base, XOutputStream : The component must have a ctor with the component context as argument.

PythonOutputStream", "com. OutputStream", , Lets assume, that this code is stored in a file named tuplestrm.

The component can be instantiated e. OutputStream" tupleStrm. For pure outparameters, a dummy None value should be used as a place holder. This is best explained with an example. Lets' assume we have the following IDL method spec long foo [in] long first, [inout] long second, [out] third A python UNO object implements such a method the following way:.

This also emphasizes, that out-parameters are quite close to multiple return values though the semantic association of a inout parameter gets lost. Example for catching from com. Message Example for throwing. There exist the functions uno. Furthermore, there exists a class unohelper.

This paragraph lists some of the unohelper. Most of the OOo API functions expect a file-url, while the python runtime functions in general only work with system paths. Most OOo function return a file-url, while most python runtime functions expect system paths. After completing the function, all services within these components can be instantiated as long as the toBeExtendedContext is not disposed. The changes are not made persistent. The typeinformation include implementation name, supported services, supported interfaces, supported methods and supported properties.

This may be a useful help when you need to debug or profile your code. The pid of the process is appended to the string e. If it exists, it puts it into sys. It also means, that you can now use the unohelper. Base implementation even if you have defined your own interface types by lazy loading the new types so that they don't get used during registration process. TokenCounter", "com.

AddIn", , Have a look at the sample calc addin to see how it works. Note that there are some negative side effects: code added through this mechanism can only be changed with a restart of the office process as it got added to sys.

This is especially limitation for script developers. These additional components currently live in the shared libraries typeconverter. Often, the components for setting up an interprocess connection are also required. These are uuresolver. On Unix, there exists two files: libpyuno. Additionally, the python module uno. Bootstrapping pyuno from the python executable When the uno module gets first imported from an arbitrary python script, it must bootstrap a properly prepared UNO component context.

Sometimes it is preferable to mention the librarynames of the desired components directly within the script instead of preparing a registry however note that the above mentioned bootstrap components always needs to be registered in a registry.
