Building the Website
Clone the repository:
git clone https://github.com/moorepants/learn-multibody-dynamics.git cd learn-multibody-dynamics
Install miniconda or Anaconda and create a conda environment for the book:
conda env create -f multibody-book-env.yml
Activate the conda environment:
conda activate multibody-book
To build the website run:
make html
When complete, the website is then viewable in your browser:
<yourbrowser> _build/html/index.html
You can also run sphinx-autobuild (updates while while you edit) with:
make autobuild
If you want to build one of the branches (for example a pull request), you'll need to fetch and checkout the branch. First fetch down all the branches:
git fetch origin
Then checkout the branch (this command is only need the first time you check it out):
git checkout -b branch-name origin/branch-name
The branch name is listed on the pull request just under the title "...wants to merge X commits into master from branch-name." Or you can find all branches here: https://github.com/moorepants/learn-multibody-dynamics/branches
Now run:
make clean make html
The make clean
makes sure you don't keep any remnants from prior builds
around before building the new branch.
After you have a new branch setup you can switch between the master branch and any branch name with just:
git checkout master git checkout branch-name
If the master branch or any other branch has been updated on github you can pull down the latest changes with:
git checkout branch-name git pull origin branch-name
Editing Guide
restructuredtext
The text is written in reStructuredText and processed with Sphinx. The Sphinx reStructuredText documentation page is a good starting point to learn the syntax.
reStructuredText doesn't enforce a specific heading order, but this should be followed for this text:
=======
Chapter
=======
Section
=======
Subsection
----------
Subsubsection
^^^^^^^^^^^^^
Autoreferencing is enabled so the above sections can be referenced with:
:ref:`Chapter`
:ref:`Section`
:ref:`Subsection`
:ref:`Subsubsection`
For equations and figures, they need to be manually labeled for numbered referencing. Use these patterns:
:label:`eq-my-equation-name`
:math:numref:`eq-my-equation-name`
.. _fig-my-figure-name:
:numref:`fig-my-figure-name`
jupyer-sphinx
We use jupyter-sphinx to transform each page with code cells into a Jupyter
Notebook and Python script. Any page that includes .. jupyter-execute::
directives will be processed in this way. The documentation for jupyter-sphinx
is here:
https://jupyter-sphinx.readthedocs.io
Xournal++
I draw the figures, one per page, in Xournal++. The I export as -> svg -> choose None for background and "current page" to get a single exported svg.
The SVG figures should be cropped to the bounding box of the drawn elements. One can do so using Inkscape with these button presses: File -> Document Properties -> Resize Page to Content. With Inkscape > 1.0 this command will crop the figure:
inkscape --export-type=svg --export-area-drawing ./my-figure.svg
Live rebuilding with sphinx-autobuild
Sphinx autobuild is a pretty good way to get almost instaneous rendered HTML versions of the reStructuredText file. You can open a window with your text editor and a window with your broswer side-by-side for almost instant feedback on the formatting and Jupyter code execution.
sphinx-autobuild -b html . _build/html/
This is also encoded in the Makefile:
make autobuild
