= Coding Style = 

== General rules ==

 - Code lines should not be longer than 80 characters
 - The formatting in general should be something similar to that Emacs C++-mode does by default. I.e.
   - use two spaces for indenting.

== Naming Conventions ==

In order to make development easier we have made some conventions
according to coding style. These include names of types, classes,
functions, variables, constants and exceptions. If these conventions
are met in one's code then it is easier to read and maintain
it. Please comply with these conventions if you want to contribute
developing LEMON library.

'''Note:''' When the coding style requires the capitalization of an abbreviation,
only the first letter should be upper case.

{{{
#!cpp
XmlReader
}}}


'''Warning:''' In some cases we diverge from these rules.
This is primary done because STL uses different naming convention and
in certain cases
it is beneficial to provide STL compatible interface.

=== File names ===

The header file names should look like the following.

{{{
#!cpp
header_file.h
}}}

Note that all standard LEMON headers are located in the {{{lemon}}} subdirectory,
so you should include them from C++ source like this:

{{{
#!cpp
#include <lemon/header_file.h>
}}}

The source code files use the same style and they have '.cc' extension.

{{{
#!cpp
source_code.cc
}}}

=== Classes and other types ===

The name of a class or any type should look like the following.

{{{
#!cpp
AllWordsCapitalizedWithoutUnderscores 
}}}

=== Methods and other functions ===

The name of a function should look like the following.

{{{
#!cpp
firstWordLowerCaseRestCapitalizedWithoutUnderscores 
}}}

=== Constants and macros ===

The names of constants and macros should look like the following.

{{{
#!cpp
ALL_UPPER_CASE_WITH_UNDERSCORES 
}}}

=== Class and instance member variables, auto variables ===

The names of class and instance member variables and auto variables (=variables used locally in methods) should look like the following.

{{{
#!cpp
all_lower_case_with_underscores 
}}}

=== Private member variables ===

Private member variables should start with underscore

{{{
#!cpp
_start_with_underscores
}}}

=== Exceptions ===

When writing exceptions please comply the following naming conventions.

{{{
#!cpp
ClassNameEndsWithException
}}}

or

{{{
#!cpp
ClassNameEndsWithError
}}}

== Template header file ==

Each LEMON header file should look like this:

{{{
#!cpp
