How do I embed source code or HTML in Open Office Org Presentations without using screenshots?

Some people says that copying code from Eclipse editor works well (UPDATE: Proven FALSE). Another alternative is exporting to RTF (can also export line numbers), or to clipboard, from Highlight and then opening/pasting it in OpenOffice.org. (UPDATE: Proven TRUE)

Here is a Highlight GUI screen shot:

You can also switch from OpenOffice.org to LibreOffice, and get COOoder from here.

This answer is perfect for the job:

• copy your code text to http://markup.su/highlighter/, and then
• copy the formatted code back to Open Office.

You can do this easily

• copy the text from you favorite editor
• go to impress, make a new text field
• press CTRL + SHIFT + V (or Edit → Paste Contents)
• and then choose Rich Text Format (RTF).

I have tested this with LibreOffice 4.2.8 under Ubuntu.

I have exactly the same problem, but with PHP code rather than C. My almost-solution is to copy the code as HTML in Kate and paste it into a temporary Open Office Writer document. That converts it to Open Office's own styled text format, and from there you can copy and paste it into Impress. Aside from the slightly annoying double-step copy-and-paste, this mostly works fine except that lines that were entirely in bold lose their emboldening and I have to manually fix them. A few other strange bugs can occur too - Impress's import of styled text from OOWriter appears to be a bit buggy.

Update: I have released this macro as a LibreOffice extension. You can install it from the official site: Code Highlighter

I had the same problem but for Java and finally I found a native solution using Python macro which is tested in LibreOffice 5.

Installation

Step 1: Install libreoffice-script-provider-python:

sudo apt-get install libreoffice-script-provider-python

Step 2: Install pygments for Python 3:

sudo pip3 install python3-pygments

Step 3: Download Highlight.py

Step 4: Copy the Highlight.py to /usr/lib/libreoffice/share/Scripts/python/

sudo cp Highlight.py /usr/lib/libreoffice/share/Scripts/python/

Step 5: Set the Read-Only permission to the script.

sudo chmod 0444 /usr/lib/libreoffice/share/Scripts/python/Highlight.py

Step 6: Open the LibreOffice Writer and goto Tools -> Customize -> Keyboard

• Select the LibreOffice option button (Available on top left corner)
• Select any desired shortcut
• Select share/Highlight/Highlight_source_code under the Functions Category
• Click on the Modify button to set the shortcut

Usage

LibreOffice Impress

• Open LibreOffice Impress.
• Insert a Text Box (Insert -> Text Box).
• Copy and paste any code snippet into that Text Box.
• Create a new Style (Right click on an existing style -> New...)
• Name the Style as code-<language>
• Apply the style to your code snippet Text Box.
• Select the Text Box.
• Use your shortcut keys to execute the macro.

LibreOffice Writer/Calc

• Open LibreOffice Writer/Calc.
• Insert a Text Box (Insert -> Text Box).
• Copy and paste any code snippet into that Text Box.
• Right click on the Text Box and select 'Description'.
• Add a description in the following format: code-<language>
• Select the Text Box
• Use your shortcut keys to execute the macro.

UPDATE:

I have added custom style support to this extension. Use code-<language> for default style and code-<language>-<style> for custom style. Available styles are listed in my Git Hub page.

For example Code-Java-Emacs will colorize the Java code using Emacs style.
