Introduction: Installation ------------ 1. Via Tools -> Extension manager in OOo/LibreOffice 2. or with unopkg tool, for example [install_path\program\]unopkg add -f lightproof_editor-0.1.oxt Usage ----- Note: there is a huge starting time (seconds) of LibreOffice with the Lightproof editor extension. [Removing the unnecessary locales from src/editor/editor.cfg of Lightproof source and generating a new editor extension can solve this problem.] The Lightproof editor extension contains a special grammar checker component and a LibreOffice Writer toolbar. The editor can update its grammar checker component based on the Lightproof rules in the current Writer document. Note: for languages without 'official LibreOffice' Hunspell dictionaries or languages with default LibreOffice grammar checking (English, Russian and Hungarian in LibO 3.5) have to modify some settings, too, see doc/manual.txt in the zipped extension, or you can choose a neutral language (eg. Esperanto) for your Writer document during the rule development. Only the Hunspell-related Lightproof functions, eg. spell(), morph() need the correct language. After the successful installation (and settings), you can check the work of the grammar checking component of the editor with the following text: a a The repeating letters will be underlined with blue wavy line (thanks to the default a a -> a # Did you mean rule of the grammar checker component of the editor).

    Unfortunately, on my win11 laptop with LO 7.4, this extension will not activate, nor can it be re-installed. Program syntax errors flash on the screen. I wonder if others have this issue.
