''' Setup script for Bokeh.

Two separate components comprise Bokeh:

* A JavaScript runtime BokehJS that draws and handles events in browsers
* Python "bindings" and an optional server for interacting with BokehJS

The BokehJS library is written in a mixture of TypeScript and pure JavaScript.
This necessitates a "compilation" step to build a complete BokehJS from these
sources, and this fact makes the Bokeh setup and install more complicated than
typical pure Python projects.

In order to build BokehJS, the first step is to make sure that the "npm"
command is installed. If you are using conda, you can typically just run

    conda install -c bokeh nodejs

Otherwise, you can find general instructions for installing NodeJS here:

    https://nodejs.org/en/download/

Once you have "npm" installed, this script can be used to build BokehJS
from the ``bokehjs`` source subdirectory, and install Bokeh into the python
source package by issuing the command:

    python setup.py install --build-js

The script also supports the standard "develop" mode that setuptools offers:

    python setup.py develop --build-js

It can take a few minutes for BokehJS to build, if you are not making changes
to the BokehJS source code, then you only need to build it once, the first
time. Subsequence invocations can be made to install the previously built
BokehJS from the ``bokehjs`` source subdirectory with the ``--install-js``
option, e.g:

    python setup.py develop --install-js

It is also possible to build BokehJS "by hand" under the ``bokehjs`` source
subdirectory. In this case, to simply install the build BokehJS quickly into
the python source tree, the following command may be issued:

    python setup.py --install-js

This will copy BokehJS from the ``bokehjs`` source directory, into the python
package directory, and perform no other actions.

Note that source distributions (sdists) are published with a pre-built BokehJS
included inside the python package, and do not include the ``bokehjs`` source.
The ``--build-js`` and ``-install-js`` options are not valid when running from
an sdist. They will be ignored, and warning printed.
