LAMMPS Documentation
Depending on how you obtained LAMMPS, this directory has 2 or 3
sub-directories and optionally 2 PDF files:
src content files for LAMMPS documentation
html HTML version of the LAMMPS manual (see html/Manual.html)
tools tools and settings for building the documentation
Manual.pdf large PDF version of entire manual
Developer.pdf small PDF with info about how LAMMPS is structured
If you downloaded LAMMPS as a tarball from the web site, all these
directories and files should be included.
If you downloaded LAMMPS from the public SVN or Git repositories, then
the HTML and PDF files are not included. Instead you need to create
them, in one of three ways:
(a) You can "fetch" the current HTML and PDF files from the LAMMPS web
site. Just type "make fetch". This should create a html_www dir and
Manual_www.pdf/Developer_www.pdf files. Note that if new LAMMPS
features have been added more recently than the date of your version,
the fetched documentation will include those changes (but your source
code will not, unless you update your local repository).
(b) You can build the HTML and PDF files yourself, by typing "make
html" followed by "make pdf". Note that the PDF make requires the
HTML files already exist. This requires various tools including
Sphinx, which the build process will attempt to download and install
on your system, if not already available. See more details below.
(c) You can genererate an older, simpler, less-fancy style of HTML
documentation by typing "make old". This will create an "old"
directory. This can be useful if (b) does not work on your box for
some reason, or you want to quickly view the HTML version of a doc
page you have created or edited yourself within the src directory.
E.g. if you are planning to submit a new feature to LAMMPS.
----------------
The generation of all documentation is managed by the Makefile in this
dir.
Options:
make html # generate HTML in html dir using Sphinx
make pdf # generate 2 PDF files (Manual.pdf,Developer.pdf)
# in this dir via htmldoc and pdflatex
make old # generate old-style HTML pages in old dir via txt2html
make fetch # fetch HTML doc pages and 2 PDF files from web site
# as a tarball and unpack into html dir and 2 PDFs
make clean # remove intermediate RST files created by HTML build
make clean-all # remove entire build folder and any cached data

Installing prerequisites for HTML build
To run the HTML documention build toolchain, Python 3 and virtualenv
have to be installed. Here are instructions for common setups:
# Ubuntu
sudo apt-get install python-virtualenv
# Fedora (up to version 21)
# Red Hat Enterprise Linux or CentOS (up to version 7.x)
sudo yum install python3-virtualenv
# Fedora (since version 22)
sudo dnf install python3-virtualenv
# MacOS X
## Python 3
Download the latest Python 3 MacOS X package from
https://www.python.org and install it. This will install both Python
3 and pip3.
## virtualenv
Once Python 3 is installed, open a Terminal and type
pip3 install virtualenv
This will install virtualenv from the Python Package Index.
