|---|
| 22 | |
|---|
| 23 | \section naming_conv Naming Conventions |
|---|
| 24 | |
|---|
| 25 | In order to make development easier we have made some conventions |
|---|
| 26 | according to coding style. These include names of types, classes, |
|---|
| 27 | functions, variables, constants and exceptions. If these conventions |
|---|
| 28 | are met in one's code then it is easier to read and maintain |
|---|
| 29 | it. Please comply with these conventions if you want to contribute |
|---|
| 30 | developing LEMON library. |
|---|
| 31 | |
|---|
| 32 | \note When the coding style requires the capitalization of an abbreviation, |
|---|
| 33 | only the first letter should be upper case. |
|---|
| 34 | |
|---|
| 35 | \code |
|---|
| 36 | XmlReader |
|---|
| 37 | \endcode |
|---|
| 38 | |
|---|
| 39 | |
|---|
| 40 | \warning In some cases we diverge from these rules. |
|---|
| 41 | This is primary done because STL uses different naming convention and |
|---|
| 42 | in certain cases |
|---|
| 43 | it is beneficial to provide STL compatible interface. |
|---|
| 44 | |
|---|
| 45 | \subsection cs-files File Names |
|---|
| 46 | |
|---|
| 47 | The header file names should look like the following. |
|---|
| 48 | |
|---|
| 49 | \code |
|---|
| 50 | header_file.h |
|---|
| 51 | \endcode |
|---|
| 52 | |
|---|
| 53 | Note that all standard LEMON headers are located in the \c lemon subdirectory, |
|---|
| 54 | so you should include them from C++ source like this: |
|---|
| 55 | |
|---|
| 56 | \code |
|---|
| 57 | #include <lemon/header_file.h> |
|---|
| 58 | \endcode |
|---|
| 59 | |
|---|
| 60 | The source code files use the same style and they have '.cc' extension. |
|---|
| 61 | |
|---|
| 62 | \code |
|---|
| 63 | source_code.cc |
|---|
| 64 | \endcode |
|---|
| 65 | |
|---|
| 66 | \subsection cs-class Classes and other types |
|---|
| 67 | |
|---|
| 68 | The name of a class or any type should look like the following. |
|---|
| 69 | |
|---|
| 70 | \code |
|---|
| 71 | AllWordsCapitalizedWithoutUnderscores |
|---|
| 72 | \endcode |
|---|
| 73 | |
|---|
| 74 | \subsection cs-func Methods and other functions |
|---|
| 75 | |
|---|
| 76 | The name of a function should look like the following. |
|---|
| 77 | |
|---|
| 78 | \code |
|---|
| 79 | firstWordLowerCaseRestCapitalizedWithoutUnderscores |
|---|
| 80 | \endcode |
|---|
| 81 | |
|---|
| 82 | \subsection cs-funcs Constants, Macros |
|---|
| 83 | |
|---|
| 84 | The names of constants and macros should look like the following. |
|---|
| 85 | |
|---|
| 86 | \code |
|---|
| 87 | ALL_UPPER_CASE_WITH_UNDERSCORES |
|---|
| 88 | \endcode |
|---|
| 89 | |
|---|
| 90 | \subsection cs-loc-var Class and instance member variables, auto variables |
|---|
| 91 | |
|---|
| 92 | The names of class and instance member variables and auto variables |
|---|
| 93 | (=variables used locally in methods) should look like the following. |
|---|
| 94 | |
|---|
| 95 | \code |
|---|
| 96 | all_lower_case_with_underscores |
|---|
| 97 | \endcode |
|---|
| 98 | |
|---|
| 99 | \subsection pri-loc-var Private member variables |
|---|
| 100 | |
|---|
| 101 | Private member variables should start with underscore. |
|---|
| 102 | |
|---|
| 103 | \code |
|---|
| 104 | _start_with_underscore |
|---|
| 105 | \endcode |
|---|
| 106 | |
|---|
| 107 | \subsection cs-excep Exceptions |
|---|
| 108 | |
|---|
| 109 | When writing exceptions please comply the following naming conventions. |
|---|
| 110 | |
|---|
| 111 | \code |
|---|
| 112 | ClassNameEndsWithException |
|---|
| 113 | \endcode |
|---|
| 114 | |
|---|
| 115 | or |
|---|
| 116 | |
|---|
| 117 | \code |
|---|
| 118 | ClassNameEndsWithError |
|---|
| 119 | \endcode |
|---|
| 120 | |
|---|
| 121 | \section header-template Template Header File |
|---|
| 122 | |
|---|
| 123 | Each LEMON header file should look like this: |
|---|
| 124 | |
|---|
| 125 | \include template.h |
|---|
| 126 | |
|---|
| 127 | */ |
