ValidatorFunction

template<typename T >

using vg::subcommand::ValidatorFunction = typedef std::function<void(const T&)>

Function type used to validate arguments. Throw std::domain_error if not allowed, explaining why.

Enumeration Type Documentation

CommandCategory

enum vg::subcommand::CommandCategory

Defines what kind of command each subcommand is.

Enumerator
PIPELINE	Some commands are part of the main build-graph, align, call variants pipeline.
TOOLKIT	Some subcommands are important parts of the toolkit/swiss army knife for working with graphs and data.
WIDGET	Some commands are less important but potentially useful widgets that let you do a thing you might need.
DEVELOPMENT	Some commands are useful really only for developers.
DEPRECATED	Some commands we're trying to move away from.

OptionFormat

enum vg::subcommand::OptionFormat

strong

Represents a pringing format for options.

SLUG
JSON
CLI

Prints the help from get_help() on an option parsing group in a nice way.

Variable Documentation
