Detailed Description

Holds a list of command-line arguments, and provides useful methods for searching and operating on them.

You can create an ArgumentList manually, or give it some argv/argc values from a main() function to parse.

Constructor & Destructor Documentation

ArgumentList() [1/4]

juce::ArgumentList::ArgumentList	(	String	executable,
		StringArray	arguments )

Creates an argument list for a given executable.

ArgumentList() [2/4]

juce::ArgumentList::ArgumentList	(	int	argc,
		char *	argv[] )

Parses a standard argv/argc pair to create an argument list.

ArgumentList() [3/4]

juce::ArgumentList::ArgumentList	(	const String &	executable,
		const String &	arguments )

Tokenises a string containing all the arguments to create an argument list.

ArgumentList() [4/4]

juce::ArgumentList::ArgumentList ( const ArgumentList & )

default

Member Function Documentation

checkMinNumArguments()

void juce::ArgumentList::checkMinNumArguments

(

int

expectedMinNumberOfArgs

)

const

Throws an error unless there are at least the given number of arguments.

containsOption()

bool juce::ArgumentList::containsOption

(

StringRef

option

)

const

Returns true if the given string matches one of the arguments. The option can also be a list of different versions separated by pipes, e.g. "--help|-h"

See also

removeOptionIfFound

failIfOptionIsMissing()

void juce::ArgumentList::failIfOptionIsMissing

(

StringRef

option

)

const

Throws an error unless the given option is found in the argument list.

getExistingFileForOption()

File juce::ArgumentList::getExistingFileForOption

(

StringRef

option

)

const

Looks for a file argument using getFileForOption() and fails with a suitable error if the file doesn't exist.

getExistingFileForOptionAndRemove()

File juce::ArgumentList::getExistingFileForOptionAndRemove

(

StringRef

option

)

Looks for a file argument using getFileForOption() and fails with a suitable error if the file doesn't exist. This works like getExistingFileForOption() but also removes the option argument (and any value arguments) from the list if they are found.

getExistingFolderForOption()

File juce::ArgumentList::getExistingFolderForOption

(

StringRef

option

)

const

Looks for a filename argument using getFileForOption() and fails with a suitable error if the file isn't a folder that exists.

getExistingFolderForOptionAndRemove()

File juce::ArgumentList::getExistingFolderForOptionAndRemove

(

StringRef

option

)

Looks for a filename argument using getFileForOption() and fails with a suitable error if the file isn't a folder that exists. This works like getExistingFolderForOption() but also removes the option argument (and any value arguments) from the list if they are found.

getFileForOption()

File juce::ArgumentList::getFileForOption

(

StringRef

option

)

const

Looks for the value of argument using getValueForOption() and tries to parse that value as a file. If the option isn't found, or if the value can't be parsed as a filename, it will throw an error.

getFileForOptionAndRemove()

File juce::ArgumentList::getFileForOptionAndRemove

(

StringRef

option

)

Looks for the value of argument using getValueForOption() and tries to parse that value as a file. This works like getFileForOption() but also removes the option argument (and any value arguments) from the list if they are found.

getValueForOption()

String juce::ArgumentList::getValueForOption

(

StringRef

option

)

const

Looks for a given argument and returns either its assigned value (for long options) or the string that follows it (for short options). The option can also be a list of different versions separated by pipes, e.g. "--help|-h" If it finds a long option, it will look for an assignment with a '=' sign, e.g. "--file=foo.txt", and will return the string following the '='. If there's no '=', it will return an empty string. If it finds a short option, it will attempt to return the argument that follows it, unless it's another option. If the argument isn't found, this returns an empty string.

indexOfOption()

int juce::ArgumentList::indexOfOption

(

StringRef

option

)

const

Returns the index of the given string if it matches one of the arguments, or -1 if it doesn't. The option can also be a list of different versions separated by pipes, e.g. "--help|-h"

operator=()

ArgumentList & juce::ArgumentList::operator= ( const ArgumentList & )

default

operator[]()

ArgumentList::Argument juce::ArgumentList::operator[]

(

int

index

)

const

Returns one of the arguments

removeOptionIfFound()

bool juce::ArgumentList::removeOptionIfFound

(

StringRef

option

)

Returns true if the given string matches one of the arguments, and also removes the argument from the list if found. The option can also be a list of different versions separated by pipes, e.g. "--help|-h"

See also

containsOption

removeValueForOption()

String juce::ArgumentList::removeValueForOption

(

StringRef

option

)

Looks for a given argument and returns either its assigned value (for long options) or the string that follows it (for short options). This works like getValueForOption() but also removes the option argument (and any value arguments) from the list if they are found.

size()

int juce::ArgumentList::size

(

)

const

Returns the number of arguments in the list.
