Public Member Functions | |
| ArgumentList (String executable, StringArray arguments) | |
| Creates an argument list for a given executable. | |
| ArgumentList (int argc, char *argv[]) | |
| Parses a standard argv/argc pair to create an argument list. | |
| ArgumentList (const String &executable, const String &arguments) | |
| Tokenises a string containing all the arguments to create an argument list. | |
| ArgumentList (const ArgumentList &)=default | |
| ArgumentList & | operator= (const ArgumentList &)=default |
| int | size () const |
| Returns the number of arguments in the list. | |
| Argument | operator[] (int index) const |
| Returns one of the arguments. | |
| void | checkMinNumArguments (int expectedMinNumberOfArgs) const |
| Throws an error unless there are at least the given number of arguments. | |
| bool | containsOption (StringRef option) const |
| Returns true if the given string matches one of the arguments. | |
| bool | removeOptionIfFound (StringRef option) |
| Returns true if the given string matches one of the arguments, and also removes the argument from the list if found. | |
| int | indexOfOption (StringRef option) const |
| Returns the index of the given string if it matches one of the arguments, or -1 if it doesn't. | |
| void | failIfOptionIsMissing (StringRef option) const |
| Throws an error unless the given option is found in the argument list. | |
| String | 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). | |
| String | 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). | |
| File | getFileForOption (StringRef option) const |
| Looks for the value of argument using getValueForOption() and tries to parse that value as a file. | |
| File | getFileForOptionAndRemove (StringRef option) |
| Looks for the value of argument using getValueForOption() and tries to parse that value as a file. | |
| File | getExistingFileForOption (StringRef option) const |
| Looks for a file argument using getFileForOption() and fails with a suitable error if the file doesn't exist. | |
| File | getExistingFileForOptionAndRemove (StringRef option) |
| Looks for a file argument using getFileForOption() and fails with a suitable error if the file doesn't exist. | |
| File | 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. | |
| File | 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. | |
Public Attributes | |
| String | executableName |
| The name or path of the executable that was invoked, as it was specified on the command-line. | |
| Array< Argument > | arguments |
| The list of arguments (not including the name of the executable that was invoked). | |
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.
| ArgumentList::ArgumentList | ( | String | executable, |
| StringArray | arguments ) |
Creates an argument list for a given executable.
| ArgumentList::ArgumentList | ( | int | argc, |
| char * | argv[] ) |
Parses a standard argv/argc pair to create an argument list.
Tokenises a string containing all the arguments to create an argument list.

| int ArgumentList::size | ( | ) | const |
Returns the number of arguments in the list.
| Argument ArgumentList::operator[] | ( | int | index | ) | const |
Returns one of the arguments.
| void ArgumentList::checkMinNumArguments | ( | int | expectedMinNumberOfArgs | ) | const |
Throws an error unless there are at least the given number of arguments.
| bool 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"
| bool 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"
| int 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"
| void ArgumentList::failIfOptionIsMissing | ( | StringRef | option | ) | const |
Throws an error unless the given option is found in the argument list.
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.
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.
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.
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.
Looks for a file argument using getFileForOption() and fails with a suitable error if the file doesn't exist.
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.
Looks for a filename argument using getFileForOption() and fails with a suitable error if the file isn't a folder that exists.
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.
| String ArgumentList::executableName |
The name or path of the executable that was invoked, as it was specified on the command-line.
The list of arguments (not including the name of the executable that was invoked).
