Further information:
Some functions will also work in Open Office Writer, Calc or Base, but many I know have properties or methods which are not available in O.O., I have not documented these as of yet. As English is my only language, of course this UDF was written for automating the English version of L.O., and may not work for other language versions.

 

Present Limitations:

There are some limitations to this UDF, they will generally be documented in the function headers. A few of the limitations are as follows:
♦ Writer:
— Performing a find format search with any of the following attributes (Orphan and Widow; Any hyphenation related settings; Vertical Alignment; Rotate and Scale; Relief; Text Direction) causes ANY words matching the search word to be deleted, whether it had those attributes or not, whether a FIND or REPLACE is performed. This is a reported L.O. bug, some will be fixed, possibly in version 7.5 or 7.6, the ones to be fixed are (Vertical Alignment; Text Direction; Relief; Rotate and Scale), the others (Orphan and Widow; All hyphenation), have a known cause, but as of yet no fix has been decided upon.

— Setting column sizing is calculated relatively, and I am unable to determine the proper calculations to interpret and set their values. They are still settable, but probably not accurately, unless you know the appropriate value to use.

— I am unable to create functions for inserting Heading or Numbered paragraph fields, I also skipped all Numbering Range Fields, as they were quite complex. I skipped Doc Info Custom Field, again due to complexity. I skipped DDE and Database fields, as I am unsure of what their use is/how they work, thus I don’t know how to test if it’s working etc., if I did make a function for them. Finally I skipped the Execute Macro field, as I didn’t see it as a wise to add the ability to automate writing and running a macro, which could possibly be used maliciously.

— Modifying Numbering Styles works fine, but due to some form of incompatibility between AutoIt and LibreOffice, the normal way of modifying the settings does not work. I thus had to find and use a work around method.

— Certain mathematical calculations are slightly inaccurate, e.g. conversion from Hue, Saturation, Brightness to Long color code format is off, but the reverse works fine? It shouldn’t cause a noticeable color difference, and you can always use RGB, HEX, or CMYK values instead, which seem to be accurate. I haven’t found why the HSB calculation is off yet.

— Creating a FileName Field with “Fixed” set to True causes the display type to be incorrect, the desired type can be achieved but not using the appropriate flag. The bug has been reported, but there has been no fix found yet.

— Image, Pattern, and Hatch Area fill aren’t available.

— Zoom type is not possible to set.

— Find and Replace in a selection using Regular expressions and formatting may cause unexpected results.

 

Possible Future Modifications:
There are some modifications/additions on the drawing board, namely:

— Adding more Field insertion/modification functions.

— Adding Image, Pattern, and Hatch Area fill.

— Add documentation for which functions will/won’t work for Open Office.

— Fill in the “Link” section.

— Possibly rename all functions to just “LOW” instead of LOWriter, for brevity.

NOTES:
—This UDF works ONLY for the installed version of LibreOffice, not the portable version. (Thank you @argumentum) The ability to Automate LibreOffice Portable (and OpenOffice) has been added, and Should work correctly. It currently adds some temporary Registry entries however. See `_LO_InitializePortable`.

—For those using older AutoIt versions, several functions use Maps. In older AutoIt installations, a syntax error will be reported due to this.

— LibreOffice uses Hundredths of a Millimeter (100th MM) for sizing internally, all functions in this UDF, unless otherwise stated, use these units. A converter has been created for converting Inches, Centimetres, Printer’s Points, and Millimetres to/from 100th MMs, for all sizing needs. See _LO_UnitConvert.

— LibreOffice uses RGB color value as a long integer for all color settings, A converter has also been created for converting from/to Hex; (R)ed, (G)reen, (Blue); (H)ue, (S)aturation, and (B)rightness; and (C)yan, (M)agenta, (Y)ellow, Blac(K); to/from long integer RGB color value. See _LO_ConvertColorFromLong, and _LO_ConvertColorToLong.

 

Acknowledgements:
 I would like to give a hearty thank you to:

— @mLipok for helping me develop this UDF.

— @water for extensive documentation work and support, as well as CHM creation.
—GMK, Leagnus, Andy G, mLipok for their OOo/LibO Calc UDF, which provided pieces needed, and a template for developing many pieces of this UDF.

—mLipok again, for his “WriterDemo.au3” (based on the LibreOffice SDK example, WriterDemo.vbs) which gave me a basic beginning on this project. Without this, I would never have found the “Bridge_GetStruct” code piece for initiating the “Properties” of L.O. As well as the basics of opening L.O. through Autoit. https://www.autoitscript.com/forum/topic/204665-libreopenoffice-writer/?do=findComment&comment=1471711

— water for his Word UDF included with Autoit, which offered a good idea of basic Word functions to create, and also good examples for UDF function layout.

— water for his Simple Library Docs Generator

— Jos and the AutoIt team for some methods and functions integrated for the CHM creation tool.

— jguinch for his Printers Management UDF, from which I used and modified _PrintMgr_EnumPrinter;

— Andrew Pitonyak for his invaluable book on writing Open Office/ Libre Office Macros, this helped me immensely with finding needed functions / properties.  OpenOffice.org Macros Explained — OOME Third Edition As well as the fourth edition, see Pitonyak's website.

— Numerous forum post, websites etc., that I have used for various problem solving, both this forum, LibreOffice's forum, Open Office's forum, and others.

Update

[argumentum]

Nice. You could put all the files in a single zip, or two.

Anyone trying this: The portable version can not work. It has to be the installed one, as otherwise the "com.sun.star.*" objects are not be available.
( this is my first time using LibreOffice )

Edit 2025: That got solved with "_LO_InitializePortable"

Edited October 27, 2025 by argumentum
the future is here. ..was here.

[donnyh13]

Thanks argumentum, that saved a lot of upload space! And also thanks for the note on the portable version, I added that to the post.

@donnyh13 

I would like to contribute but.. would you like to use github to manage this project ?

[donnyh13]

@mLipok,

We could, I've never used Github before though? I imagine it would be easier for sure, considering I'm not always available. And thanks for offering to help, it would be much appreciated!

@Danp2 and @SOLVE-SMART

Is it possible to few github users be maintainers of the project at the same time ?

 

btw.
I would like to suggest to start ths project as LibreOffice not only for LibreOfficeWriter

IMHO we should finally make it happend and create one good UDF for entire LibreOffice.

I actually had similar thoughts. That would be great.

So would you agree that I create GitHub archive for this project ?
I can add you as maintainers.

 

What you think ?

If not, I would like to suggest you create the project, if you want, as I'm pretty sure you'll be more active at updates etc.

As you can see as so far I do not push any code there
As I wait for your aproval.

 

[mLipok]

btw.
Examples.zip contains 2 folders:   "Examples"   and  "Libre Office Writer Examples"

Which are most recent ?
Which are valid ?

What ever you figure, not knowledgable on all these things, but googling makes it sound good to me.

Looks good to me, I'll update the thread and paste the URL there too.

Like I said, I've never used GitHub before, so feel free to lead the way.

Sorry, thanks for catching that. "Examples" is most recent/ valid.

A few thoughts about your project.

• I think it is a big project with a lot of work (DESIGN, coding, testing, debugging, documenting ...) you have started. I have emphasised the DESIGN phase as this is - from my point of view - crucial for such a big project.
• If I would start such a project I would
  • run a poll to see how many users have the need to automate OO/LO
  • Ask people about their priority. Means: Which modules do they need most (Writer, Calc, ...)
• I would split this project into multiple files:
  • a general file with those functions needed by all modules like copy/paste, formatting, saving/exporting ...
  • a file for each module
• I would try to copy the functionality from Word/Excel UDF to OO/LO because the user's requirements are always the same, regardless of the software product used.

Just my 2 cents worth.

Good luck with your project!
