Advanced Techniques in LibreOffice Writer: Master Documents, Macros and Custom Styles

In this post, we’ll explore some of the advanced features in LibreOffice Writer that can significantly boost your productivity, especially when dealing with complex or lengthy documents. These features will help you automate repetitive tasks, manage large projects more efficiently, and customise the look and feel of your documents in great detail.

By the end of this post, you’ll know how to create and manage Master Documents, use Macros for automation, and design Custom Styles for consistent formatting across all your projects.

Step 1: Working with Master Documents

A Master Document in LibreOffice Writer is a powerful tool that allows you to manage and organise large documents by splitting them into smaller sub-documents. This is useful for creating books, reports, or any project where individual sections can be handled as separate files.

Creating a Master Document

1. Open a New Master Document:
   • Go to File > New > Master Document. This opens a blank master document.
2. Insert Sub-Documents:
   • Click Insert > File and select the files you want to include in your master document. Each file will be treated as a sub-document.
   • You can rearrange the order of the sub-documents in the Navigator (press F5 to open the Navigator).
3. Creating Sections and Table of Contents:
   • In the Navigator, right-click on a sub-document and select Create Section to divide your content into manageable sections.
   • You can also add a Table of Contents in your master document by going to Insert > Table of Contents and Index > Table of Contents.

Benefits of Using Master Documents:

• Easy Organisation: Divide large documents into manageable sections.
• Independent Editing: Each sub-document can be edited separately, reducing the complexity of handling one massive file.
• Automatic Updates: Changes made in sub-documents will automatically update the master document.

Step 2: Automating Tasks with Macros

Macros are an essential tool for automating repetitive tasks in LibreOffice Writer. A macro is a sequence of instructions that can be recorded and then played back to perform tasks automatically.

Recording a Macro

1. Enable Macro Recording:
   • Before you can record macros, you need to enable the feature. Go to Tools > Options > LibreOffice > Advanced and check the box that says Enable macro recording.
2. Record Your First Macro:
   • Go to Tools > Macros > Record Macro.
   • Perform the actions you want to automate. For example, you could format a block of text with a specific font, size, and alignment.
   • Once you’re done, click Stop Recording.
3. Save the Macro:
   • The Macro dialog will appear, allowing you to name and save the macro. Click Save.
4. Running the Macro:
   • To run your saved macro, go to Tools > Macros > Run Macro.
   • Select your macro from the list and click Run. The actions you recorded will be applied to the document.

Editing a Macro

1. Open the Macro Editor:
   • To modify a macro, go to Tools > Macros > Organise Macros > LibreOffice Basic.
   • Select the macro you want to edit, then click Edit.
2. Customise the Code:
   • LibreOffice macros are written in LibreOffice Basic, a programming language similar to Visual Basic. You can edit the macro code directly to add more complex functionality.

Step 3: Designing and Managing Custom Styles

Styles are one of the most powerful tools in LibreOffice Writer. Custom styles allow you to apply consistent formatting across an entire document or series of documents, ensuring that everything from headings to body text looks exactly the way you want.

Creating a Custom Paragraph Style

1. Open the Styles Sidebar:
   • Go to View > Styles or press F11 to open the Styles sidebar.
2. Create a New Style:
   • Right-click in the Paragraph Styles area and select New.
   • In the Organiser tab, give your style a name (e.g., “My Custom Heading”).
3. Customise the Style:
   • In the Font tab, choose the font, size, and other attributes.
   • In the Alignment tab, select how you want the text aligned (left, right, centre, justify).
   • Use the Indents & Spacing tab to define margins and line spacing.
   • Once you’re satisfied, click OK to save your custom style.
4. Applying Your Custom Style:
   • Select any paragraph in your document and click on your custom style in the sidebar to apply it.

Modifying a Style

1. Right-Click to Modify:
   • If you need to change a style, simply right-click on it in the sidebar and choose Modify.
2. Make Adjustments:
   • Edit the style settings in the same dialog where you created it, then click OK.

Style Hierarchies:

• LibreOffice allows you to create parent-child relationships between styles. For example, if you create a base style for headings and then create variations of that style (e.g., Heading 1, Heading 2), you can make global changes by modifying the parent style.

Step 4: Creating and Using Page Styles

Page Styles allow you to control the layout of different sections of your document. For instance, you can have different headers or footers for the first page, or apply different margins for sections.

Creating a Custom Page Style

1. Open the Styles Sidebar:
   • Go to View > Styles > Page Styles.
2. Create a New Page Style:
   • Right-click and select New.
   • In the Organiser tab, give your page style a name.
3. Customise the Layout:
   • In the Page tab, set the margins, paper size, and orientation (portrait or landscape).
   • In the Header and Footer tabs, you can control whether these elements appear on your pages.
4. Apply the Page Style:
   • Click on the Page Styles icon in the sidebar and select your custom style.

Step 5: Advanced Table of Contents and Indexing

In the intermediate post, we covered the basics of creating a Table of Contents (TOC). Now let’s go further by customising your TOC and using advanced indexing features.

Customising the Table of Contents

1. Modify the Structure:
   • Right-click the Table of Contents and choose Edit Index/Table.
   • Under the Entries tab, you can customise how the TOC entries appear. For instance, you can add a “Chapter” label before each heading or change the leader (the dots between the heading and page number).
2. Changing TOC Levels:
   • In the Create from section, you can choose how many heading levels to include in the TOC (e.g., just Heading 1 and Heading 2, or all heading levels).
3. Updating the TOC:
   • Whenever you make changes to your document, right-click the TOC and select Update Index to refresh it with the latest information.

Inserting an Index

1. Add Index Markers:
   • Select the words you want to include in the index (e.g., key terms, names).
   • Go to Insert > Indexes and Tables > Entry to add an index entry.
2. Insert the Index:
   • Place your cursor where you want the index to appear.
   • Go to Insert > Indexes and Tables > Indexes and Tables.
   • Customise the structure and formatting in the dialog, then click OK.

Step 6: Using Fields for Advanced Automation

We’ve already covered basic fields like page numbers, but LibreOffice Writer also allows you to use more advanced fields for dynamic content.

Conditional Fields

1. Insert a Conditional Field:
   • Go to Insert > Field > More Fields and switch to the Functions tab.
   • Select Conditional Text from the list.
2. Define the Condition:
   • In the Condition box, type a condition (e.g., a custom variable or expression).
   • Enter the text to be displayed if the condition is true or false.

Setting Custom Variables

1. Insert a Variable Field:
   • Go to Insert > Field > More Fields and switch to the Variables tab.
   • Select Set Variable from the list.
2. Define the Variable:
   • Enter a name and value for the variable. You can reference this variable later in your document by using the Show Variable option in the same dialog.

Final Thoughts
