Kindle e-readers allow readers to lookup meanings on-the-fly. If you encounter a benevolent guide or read classic Bengali literature, the instant pop-up window decodes the word seamlessly. Simply click the underlined words to test how our compiled dictionary files display definitions inside the Kindle preview lookup pane!

বাংলা শব্দভাণ্ডার সমৃদ্ধ করতে আমরা এই প্রকল্পে বিশদ বিশ্লেষণ করেছি। উদাহরণস্বরূপ, যদি আপনি একজন হিতৈষী ব্যক্তির খোঁজ করেন, তবে তার পরিচয় এবং সঠিক বাংলা অভিধান অর্থ সহজেই জানা সম্ভব হবে।

Local Development

macOS Development Environment

macOS is the primary testing platform. The compilation script automatically searches the applications folder to locate the compiler embedded inside Kindle Previewer 3.

Requires Python 3.8+
Install the official Kindle Previewer 3 (macOS Package)

# Clone the repository
git clone https://github.com/tahmidxp96/Shobdo-Vandar.git
cd Shobdo-Vandar

# Run the full ingestion and compilation suite
python3 kindle_dictionary_builder.py

# Lookup/preview entry formatting inside terminal
python3 kindle_dictionary_builder.py -p "benevolent"

Windows Development Environment

Windows builds require extracting and placing the Amazon kindlegen command line binary in the repository's root directory.

Requires Python 3.8+ for Windows
Install Kindle Previewer 3 (Windows Installer)
Copy kindlegen.exe from AppData\Local\Amazon\Kindle Previewer 3\lib\fc\bin\kindlegen.exe into the root folder of the cloned repository.

:: Clone repository and copy kindlegen.exe to the folder
git clone https://github.com/tahmidxp96/Shobdo-Vandar.git
cd Shobdo-Vandar

:: Execute python build script
python kindle_dictionary_builder.py

Linux Development Environment

Amazon does not distribute Kindle Previewer 3 for Linux. A legacy KindleGen binary must be used, which requires 32-bit execution libraries on modern 64-bit systems.

Requires Python 3.8+
Download legacy KindleGen v2.9 for Linux
Copy the extracted kindlegen binary to the repository root and make it executable: chmod +x kindlegen

# Install 32-bit compatibility libraries on Debian/Ubuntu host
sudo apt-get update
sudo apt-get install libc6-i386

# Compile dictionaries
python3 kindle_dictionary_builder.py
