  • Short options with arguments
  • Long option flags
  • Long options with arguments
• Positional arguments
• Development

Argument types

Short option flags

Example: -a -b -c / -abc

Usage: Simple boolean flags

Short options with arguments

Example: -A/tmp/file.png / -A /tmp/file.png

Usage: Simple parameters with a value. If no space is provided the argument must be capitalized.

Long option flags

Example: --version

Usage: Same as Short option flags, but taken from GNU

Long options with arguments

Example: --output=/tmp/file.png / --output /tmp/file.png

Usage: Same as Short options with arguments, but taken from GNU. Can be separated with either space or an equal sign (=).

Positional arguments

Any arguments subsequent to options/flags will be parsed as positional arguments.

Using -- causes everything to the right to be threated as positional arguments.

Development

• Use make test to run tests on the project.
• Use make coverage to create tests/coverage.html with the test coverage of the library.
