OOO Development Tools

License Apache PyPI - Python Version PyPI - Wheel Test Badge Github

OOO Development Tools (OooDev) is intended for programmers who want to learn and use the Python version of the LibreOffice API.

This allows Python to control and manipulate LibreOffice’s text, drawing, presentation, spreadsheet, and database applications, and a lot more (e.g. its spell checker, forms designer, and charting tools).

One of the aims is to develop utility code to help flatten the steep learning curve for the API. For example, The Lo class simplifies the steps needed to initialize the API (by creating a connection to a LibreOffice process), to open/create a document, save it, and close down LibreOffice.

Currently this project has been tested on LibreOffice in Windows and Linux (Ubuntu).

Advantages of Python

Macros are pieces of programming code that runs in office suites and helps automate routine tasks. Specifically, in LibreOffice API these codes can be written with so many programming languages thanks to the Universal Network Objects (UNO).

Since LibreOffice is multi-platform we can use our documents at different platforms like Mac, Windows, and Linux. So we need a cross-platform language to run our macros at different platforms.

Python has the advantage that it is cross-platform and can run inside the office environment as macros and outside office environment on the command line.

Python has a vast set libraries that can be used in a project, including Numpy and Numexpr which are excellent and powerful at numeric computation.

This makes Python and excellent choice with maximum flexibility.

Command Line Help

There are many classes and methods in this project. For this reason OooDev has a command line tool OooDev CLI Help. that can be used to search the documentation for classes and methods this project. Choosing a number from a search result opens you web browser to that class or method in the documentation.

OooDev CLI Help is built from Sphinx CLI Help, so see the Wiki Searching help and substitute cli-hlp with odh on command line instructions.

Example Usage:

odh hlp -s Write.append

Choose an option (default 1):
[0],  Cancel (or press q followed by enter)
[1],  ooodev.office.write.Write.append                                 - method     - py
[2],  ooodev.office.write.Write.append_date_time                       - method     - py
[3],  ooodev.office.write.Write.append_line                            - method     - py
[4],  ooodev.office.write.Write.append_para                            - method     - py

Note that OooDev CLI Help is a separate project and is not required to use this project. Also OooDev CLI Help use python built in sqlite which is not shipped with LibreOffices’s python on Windows. This means some configurations will not allow OooDev CLI Help to run on Windows. In this case you can install OooDev CLI Help on a global scope and use it that way if needed.
