Installation

Install with pip (preferred method)

Recommended because it will be easier to update going forward, especially if you prefer to have the script installed.

1. Install Python 3.9+ if not allready installed

2. Install imajin using pip:

   pip install imajin
   

   You should be all set up to use imajin directly from the command line.

Download and install script

Not recommended, because it's harder to update.

1. Install Python 3.9+ if not already installed.

2. Download the source folder, either by downloading the Source code from the Latest Release or using git clone https://github.com/YonKuma/imajin.py.git

3. Install dependencies:

   pip install -r requirements.txt
   

   You can now use imajin.py as a python script. For example, if you're in the source directory, you can use python imajin.py -r 蹴散らす ~/Documents/Manga, but you'll need to use a qualified path to the files you want to search

4. (Optional) You can install imajin by copying the script to somewhere in your PATH and making it executable

   sudo cp imajin.py /usr/local/bin/imajin
   sudo chmod +x /usr/local/bin/imajin
   

Dependencies

Dependencies:

• beautifulsoup4
• lxml
• mecab-python3 (optional; smart matching will be disabled if MeCab is not available)
• unidic-lite (optional; used for smart matching. Other dictionaries should work but are harder to install)
