Detailed Description

Command line parser for extracting flags, values, and strings.

Constructor & Destructor Documentation

commandLine() [1/2]

| commandLine::commandLine | ( | const int | argc, | | | | char ** | argv, | | | | const char * | extraFlag = NULL | | | ) | | |

Constructor, takes the command line from main()

commandLine() [2/2]

| commandLine::commandLine | ( | const int | argc, | | | | char ** | argv, | | | | const char ** | extraArgs | | | ) | | |

Constructor, takes the command line from main()

Member Function Documentation

AddArg()

| void commandLine::AddArg | ( | const char * | arg | ) | |

Add an argument to the command line.

AddArgs()

| void commandLine::AddArgs | ( | const char ** | args | ) | |

Add arguments to the command line.

AddFlag()

| void commandLine::AddFlag | ( | const char * | flag | ) | |

Add a flag to the command line.

GetFlag()

| bool commandLine::GetFlag | ( | const char * | argName, | | | | bool | allowOtherDelimiters = true | | | ) | | const |

Checks to see whether the specified flag was included on the command line.

For example, if argv contained --foo, then GetFlag("foo") would return true

Parameters

| allowOtherDelimiters | if true (default), the argName will be matched against occurances containing either - or _.
For example, --foo-bar and --foo_bar would be the same. |

Returnstrue, if the flag with argName was found false, if the flag with argName was not found

GetFloat()

| float commandLine::GetFloat | ( | const char * | argName, | | | | float | defaultValue = 0.0f, | | | | bool | allowOtherDelimiters = true | | | ) | | const |

Get float argument.

For example if argv contained --foo=3.14159, then GetInt("foo") would return 3.14159f

Parameters

| allowOtherDelimiters | if true (default), the argName will be matched against occurances containing either - or _.
For example, --foo-bar and --foo_bar would be the same. |

ReturnsdefaultValue if the argument couldn't be found. (0.0 by default). Otherwise, returns the value of the argument.

GetInt()

| int commandLine::GetInt | ( | const char * | argName, | | | | int | defaultValue = 0, | | | | bool | allowOtherDelimiters = true | | | ) | | const |

Get integer argument.

For example if argv contained --foo=100, then GetInt("foo") would return 100

Parameters

| allowOtherDelimiters | if true (default), the argName will be matched against occurances containing either - or _.
For example, --foo-bar and --foo_bar would be the same. |

ReturnsdefaultValue if the argument couldn't be found (0 by default). Otherwise, returns the value of the argument.

GetPosition()

| const char* commandLine::GetPosition | ( | unsigned int | position, | | | | const char * | defaultValue = NULL | | | ) | | const |

Get positional string argument.

Positional arguments aren't named, but rather referenced by their index in the list. For example if the command line contained my-program --foo=bar /path/to/my_file.txt, then GetString(0) would return `"/path/to/my_file.txt"

ReturnsdefaultValue if the argument couldn't be found (NULL by default). Otherwise, returns a pointer to the argument value string from the argv array.

GetPositionArgs()

| unsigned int commandLine::GetPositionArgs | ( | | ) | const |

Get the number of positional arguments in the command line.

Positional arguments are those that don't have a name.

GetString()

| const char* commandLine::GetString | ( | const char * | argName, | | | | const char * | defaultValue = NULL, | | | | bool | allowOtherDelimiters = true | | | ) | | const |

Get string argument.

For example if argv contained --foo=bar, then GetString("foo") would return "bar"

Parameters

| allowOtherDelimiters | if true (default), the argName will be matched against occurances containing either - or _.
For example, --foo-bar and --foo_bar would be the same. |

ReturnsdefaultValue if the argument couldn't be found (NULL by default). Otherwise, returns a pointer to the argument value string from the argv array.

GetUnsignedInt()

| uint32_t commandLine::GetUnsignedInt | ( | const char * | argName, | | | | uint32_t | defaultValue = 0, | | | | bool | allowOtherDelimiters = true | | | ) | | const |

Get unsigned integer argument.

For example if argv contained --foo=100, then GetUnsignedInt("foo") would return 100

Parameters

| allowOtherDelimiters | if true (default), the argName will be matched against occurances containing either - or _.
For example, --foo-bar and --foo_bar would be the same. |

ReturnsdefaultValue if the argument couldn't be found, or if the value was negative (0 by default). Otherwise, returns the parsed value.

Print()

| void commandLine::Print | ( | | ) | const |

Print out the command line for reference.

Member Data Documentation

argc

| int commandLine::argc |
