Guidelines for C++ code comments¶
There are two types of code comments for C++ files: doxygen style and C++ style comments.
Doxygen styled comments are used for describing things like the purpose of the function, which parameters it accepts, and what output it generates.
Use Doxygen style comments in the header (
.h
) files. Avoid using them in.cpp
files.Do not duplicate code in comments.
Generate HTML from doxygen comments¶
To generate HTML output of the doxgyen comments,
in the build directory,
run cmake
with developer documentation on:
cmake -Dwith-devdoc=ON path/to/nest-simulator.
then
make docs
xdg-open doc/doxygen/html/index.html

See the official doxygen documentation for details.
Doxygen style¶
Multi-line comments
/**
* Short description
*
* Further details, if necesary
*/
Note
Functions and classes should use the multi-line style even for single line comments.
Single or two line comments to use with variables:
//! The maximum delay of the simulation
long may_delay;
If a short comment is needed for variables, you can add a comment to the right of the code:
long max_delay_; //!< The maximum delay of the simulation
