Installing

Debian

An official Debian package should be available soon.

You can also manually build a Debian package using the debian/sid branch, or download pre-built .debs via GitHub releases.

NixOS

An official package is also available in nixpkgs (un)stable.

Using pip

$ pip install jiten

NB: depending on your system you may need to use e.g. pip3 --user instead of just pip.

From git

NB: this installs the latest development version, not the latest release.

$ git clone https://github.com/obfusk/jiten.git
$ cd jiten
$ make
$ pip install -e .

NB: you may need to add e.g. ~/.local/bin to your $PATH in order to run jiten.

To update to the latest development version:

$ cd jiten
$ git pull --rebase
$ make

Dependencies

Python >= 3.8 + Flask + click + kanjidraw.
To build the SQLite PCRE C extension: a C compiler (e.g. gcc/clang) and the sqlite3 & pcre libraries & headers.
Basic build tools like make and patch.
To run the WebView GUI: pywebview >= 3.3.5.

Debian/Ubuntu

$ apt install python3-dev build-essential libsqlite3-dev libpcre3-dev
$ apt install python3-flask   # optional: Flask & click w/o pip

NB: currently, you'll need to install kanjidraw manually (i.e. using pip or from git).

Optional: WebView GUI

$ apt install python3-pyqt5.qtwebengine   # recommended: qtwebengine

$ apt install python3-webview             # if >= 3.3.5
$ pip3 --user install pywebview           # otherwise

Miscellaneous

Online Android App

There is also an online android app -- Jiten [Online] -- which essentially provides the same functionality as opening the https://jiten.obfusk.dev website in a web browser.

It does have some some small advantages (like long press for tooltips) and requires less storage space (and could be faster depending on your device and internet connection). You can install both at the same time if you want.

Web Interface on Android

You can also run the web interface locally (& offline) on your android phone. First, install termux, then run:

$ apt install clang python
$ pip install jiten

You can then run the web interface with:

$ jiten serve

and open http://localhost:5000 in your browser.

The web interface will keep running until you close termux or reboot.
