Public Member Functions | |
| template<typename Number > | |
| AsNumberWithUnit (std::map< std::string, Number > mapping, Options opts=DEFAULT, const std::string &unit_name="UNIT") | |
| Public Member Functions inherited from Validator | |
| Validator (std::string validator_desc) | |
| Construct a Validator with just the description string. | |
| Validator (std::function< std::string(std::string &)> op, std::string validator_desc, std::string validator_name="") | |
| Construct Validator from basic information. | |
| Validator & | operation (std::function< std::string(std::string &)> op) |
| Set the Validator operation function. | |
| std::string | operator() (std::string &str) const |
This is the required operator for a Validator - provided to help users (CLI11 uses the member func directly) | |
| std::string | operator() (const std::string &str) const |
This is the required operator for a Validator - provided to help users (CLI11 uses the member func directly) | |
| Validator & | description (std::string validator_desc) |
| Specify the type string. | |
| CLI11_NODISCARD Validator | description (std::string validator_desc) const |
| Specify the type string. | |
| CLI11_NODISCARD std::string | get_description () const |
| Generate type description information for the Validator. | |
| Validator & | name (std::string validator_name) |
| Specify the type string. | |
| CLI11_NODISCARD Validator | name (std::string validator_name) const |
| Specify the type string. | |
| CLI11_NODISCARD const std::string & | get_name () const |
| Get the name of the Validator. | |
| Validator & | active (bool active_val=true) |
| Specify whether the Validator is active or not. | |
| CLI11_NODISCARD Validator | active (bool active_val=true) const |
| Specify whether the Validator is active or not. | |
| Validator & | non_modifying (bool no_modify=true) |
| Specify whether the Validator can be modifying or not. | |
| Validator & | application_index (int app_index) |
| Specify the application index of a validator. | |
| CLI11_NODISCARD Validator | application_index (int app_index) const |
| Specify the application index of a validator. | |
| CLI11_NODISCARD int | get_application_index () const |
| Get the current value of the application index. | |
| CLI11_NODISCARD bool | get_active () const |
| Get a boolean if the validator is active. | |
| CLI11_NODISCARD bool | get_modifying () const |
| Get a boolean if the validator is allowed to modify the input returns true if it can modify the input. | |
| Validator | operator& (const Validator &other) const |
| Combining validators is a new validator. | |
| Validator | operator| (const Validator &other) const |
| Combining validators is a new validator. | |
| Validator | operator! () const |
| Create a validator that fails when a given validator succeeds. | |
Additional Inherited Members | |
| Protected Member Functions inherited from Validator | |
| Validator (std::string validator_desc, std::function< std::string(std::string &)> func) | |
| Protected Attributes inherited from Validator | |
| std::function< std::string()> | desc_function_ {[]() { return std::string{}; }} |
| This is the description function, if empty the description_ will be used. | |
| std::function< std::string(std::string &)> | func_ {[](std::string &) { return std::string{}; }} |
| This is the base function that is to be called. | |
| std::string | name_ {} |
| The name for search purposes of the Validator. | |
| int | application_index_ = -1 |
| A Validator will only apply to an indexed value (-1 is all elements) | |
| bool | active_ {true} |
| Enable for Validator to allow it to be disabled if need be. | |
| bool | non_modifying_ {false} |
| specify that a validator should not modify the input | |
Multiply a number by a factor using given mapping.
Can be used to write transforms for SIZE or DURATION inputs.
Example: With mapping = {"b"->1, "kb"->1024, "mb"->1024*1024} one can recognize inputs like "100", "12kb", "100 MB", that will be automatically transformed to 100, 14448, 104857600.
Output number type matches the type in the provided mapping. Therefore, if it is required to interpret real inputs like "0.42 s", the mapping should be of a type <string, float> or <string, double>.

CASE_SENSITIVE/CASE_INSENSITIVE controls how units are matched. UNIT_OPTIONAL/UNIT_REQUIRED throws ValidationError if UNIT_REQUIRED is set and unit literal is not found.
