The Jython Book

This is an open reference book on the Jython language, an implementation of Python implemented in, and highly interoperable with, Java. It is maintained as a reference to the current version of Jython (perhaps with a touch of lag).

How to Build the Jython Book from Source

Install and Build

Building locally requires Python 3.5 or above. Use of a virtual environment is recommended in order to isolate this project’s dependencies (the tools). All you need to begin with is an installed Python.

Instructions for Windows Powershell.

1. Create a working directory, say dg-jython, and cd into it. There, clone this repository:

   PS dg-jython> git clone https://github.com/jython/book.git
   

   These instructions assume you cloned into the directory book, a sub-directory of your working directory. Do not cd into book: the build runs from the current directory: it will create a sub-directory build to hold the generated files.

2. If you do not have virtualenv, install it:

   PS dg-jython> python3 -m pip install virtualenv
   

   (You may need to specify python3 explicitly as shown, or py -3, or it may just be python depending on your set-up.)

3. Now create a virtual environment, activate it and install the tools.

   PS dg-jython> python3 -m virtualenv venv
   ...
   PS dg-jython> .\venv\Scripts\activate
   (venv) PS dg-jython> pip install -r .\book\requirements.txt
   ...
   

4. You can now build the book as HTML in ./build with the command:

   (venv) PS dg-jython> sphinx-build -N -b html book build\html
   

   (The option -N suppresses output formatting that impedes reading on a PoSH console.)

Open build\html\index.html with your browser to view the generated documentation.

Instructions for Linux.

On Linux, the same process looks like this:

$ python3 -m pip install virtualenv
...
$ python3 -m virtualenv venv
Using base prefix '/usr'
...
$ source venv/bin/activate
(venv) $ pip install -r book/requirements.txt
(venv) $ sphinx-build -b html book build/html
...

Open build/html/index.html with your browser to view the generated documentation.

Edit and Build

After edits to the restructured text files, rerun sphinx-build -b html book build/html to regenerate the documentation.
