\section naming_conv Naming Conventions
alpar@40
    24
alpar@40
    25
In order to make development easier we have made some conventions
alpar@40
    26
according to coding style. These include names of types, classes,
alpar@40
    27
functions, variables, constants and exceptions. If these conventions
alpar@40
    28
are met in one's code then it is easier to read and maintain
alpar@40
    29
it. Please comply with these conventions if you want to contribute
alpar@40
    30
developing LEMON library.
alpar@40
    31
alpar@40
    32
\note When the coding style requires the capitalization of an abbreviation,
alpar@40
    33
only the first letter should be upper case.
alpar@40
    34
alpar@40
    35
\code
alpar@40
    36
XmlReader
alpar@40
    37
\endcode
alpar@40
    38
alpar@40
    39
alpar@40
    40
\warning In some cases we diverge from these rules.
alpar@41
    41
This is primary done because STL uses different naming convention and
alpar@40
    42
in certain cases
alpar@40
    43
it is beneficial to provide STL compatible interface.

\subsection cs-files File Names
alpar@40
    46
alpar@40
    47
The header file names should look like the following.
alpar@40
    48
alpar@40
    49
\code
alpar@40
    50
header_file.h
alpar@40
    51
\endcode
alpar@40
    52
alpar@40
    53
Note that all standard LEMON headers are located in the \c lemon subdirectory,
alpar@40
    54
so you should include them from C++ source like this:
alpar@40
    55
alpar@40
    56
\code
alpar@40
    57
#include <lemon/header_file.h>
alpar@40
    58
\endcode
alpar@40
    59
alpar@40
    60
The source code files use the same style and they have '.cc' extension.
alpar@40
    61
alpar@40
    62
\code
alpar@40
