MDICT CPP

A C++ implementation for interpreting MDX/MDD dictionary files. This library provides functionality to read and parse MDX/MDD dictionary files commonly used in electronic dictionaries.

Features

• Parse MDX/MDD dictionary files
• Extract dictionary entries and definitions
• Support for both MDX (dictionary content) and MDD (resource files)
• Simple and efficient C++ implementation

Installation

Prerequisites

• CMake (version 3.10 or higher)
• C++ compiler with C++17 support
• Git

Building from Source

1. Clone the repository:

git clone [email protected]:dictlab/mdict-cpp.git
cd mdict-cpp

2. Initialize and update submodules:

git submodule init
git submodule update --recursive

3. Build the project:

mkdir build
cd build
cmake ..
make

System Installation

To install the library system-wide (requires root privileges):

mkdir build
cd build
cmake -DINSTALL_TO_SYSTEM=ON ..
make
sudo make install

it will install those files:

-- Installing: /usr/local/lib/libmdict.a
-- Installing: /usr/local/lib/libmdictminiz.a
-- Installing: /usr/local/lib/libmdictbase64.a
-- Up-to-date: /usr/local/include/mdict/mdict.h
-- Up-to-date: /usr/local/include/mdict/mdict_extern.h
-- Installing: /usr/local/bin/mydict

This will install:

• The library to /usr/lib (Linux) or /usr/local/lib (macOS/BSD)
• Headers to /usr/include (Linux) or /usr/local/include (macOS/BSD)

Usage

Building the Executable

mkdir build
cd build
cmake ..
make mydict

The executable will be generated at build/bin/mydict

Running the Dictionary Tool

Query a word

./build/bin/mydict your_mdx_file.mdx yourword
# output the resource binary as base64 format
./build/bin/mydict your_mdx_file.mdd \\xxx\\xx.png

# output the resource binary as hex string format
./build/bin/mydict -x your_mdx_file.mdd \\xxx\\xx.png

list all keys

./build/bin/mydict -l your_mdx_file.mdx

./build/bin/mydict -l your_mdx_file.mdd

Building the Library

mkdir build
cd build
cmake ..
make mdict

The library will be generated at target/lib/libmdict.a

Using the Library in Your Project with CMake

1. Include the header files:

#include "mdict_extern.h"

2. Link against the library:

target_link_libraries(your_project mdict)

Or use g++ directly

# after make install
cd src
g++ -std=c++17 -I/usr/local/ -I. -L/usr/local/lib -lmdict -lmdictminiz -lmdictbase64 mydict.cc -o mmdict

MDX File Format

The MDX/MDD file format is a dictionary format commonly used in electronic dictionaries. MDX files contain the dictionary content (text, HTML, etc.), while MDD files contain associated resources (images, audio, etc.).
