Function Documentation

◆ require_true()

void rcpputils::require_true	(	bool	condition,
		const std::string &	msg = `"invalid argument passed"`
	)

inline

Check that an argument condition passes.

Parameters

condition	condition that is asserted to be true
msg	message to pass to exception when condition is false

Exceptions

std::invalid_argument if the condition is not met.

◆ check_true()

void rcpputils::check_true	(	bool	condition,
		const std::string &	msg = `"check reported invalid state"`
	)

inline

Check that a state condition passes.

Parameters

condition	condition to check whether it is true or not
msg	message to pass to exception when condition is false

Exceptions

rcpputils::IllegalStateException if the condition is not met.

◆ assert_true()

void rcpputils::assert_true	(	bool	condition,
		const std::string &	msg = `"assertion failed"`
	)

inline

Assert that a condition passes.

This function behaves similar to assert, except that it throws instead of invoking abort(). It is only enabled when NDEBUG is not defined

Parameters

condition	condition to check whether it's true or not
msg	message to pass to exception when condition is not met.

Exceptions

rcpputils::AssertionException if the macro NDEBUG is not set and the condition is not met.

◆ find_and_replace() [1/2]

template<class CharT , class Traits = std::char_traits<CharT>, class Allocator = std::allocator<CharT>>

std::basic_string<CharT, Traits, Allocator> rcpputils::find_and_replace	(	const std::basic_string< CharT, Traits, Allocator > &	input,
		const std::basic_string< CharT, Traits, Allocator > &	find,
		const std::basic_string< CharT, Traits, Allocator > &	replace
	)

Find and replace all instances of a string with another string.

Parameters

[in]	input	The input string.
[in]	find	The substring to replace.
[in]	replace	The string to substitute for each occurrence of `find`.

Returns: A copy of the input string with all instances of the string find replaced with the string replace.

◆ find_and_replace() [2/2]

template<typename InputT , typename FindT , typename ReplaceT >

auto rcpputils::find_and_replace	(	InputT &&	input,
		FindT &&	find,
		ReplaceT &&	replace
	)

Find and replace all instances of a string with another string.

Parameters

[in]	input	The input string.
[in]	find	The substring to replace.
[in]	replace	The string to substitute for each occurrence of `find`.

Returns: A copy of the input string with all instances of the string find replaced with the string replace.

◆ find_library_path()

std::string rcpputils::find_library_path ( const std::string & library_name )

Find a library located in the OS's specified environment variable for library paths.

The environment variable and file format per platform:

Linux: ${LD_LIBRARY_PATH}, lib{}.so
Apple: ${DYLD_LIBRARY_PATH}, lib{}.dyld
Windows: PATH%, {}.dll

Parameters

[in] library_name Name of the library to find.

Returns: The absolute filesystem path, including the appropriate prefix and extension

Exceptions

std::runtime_error if an error is encountered when accessing environment variables.

◆ get_env_var()

std::string rcpputils::get_env_var ( const char * env_var )

Retrieve the value of the given environment variable if it exists, or "".

◆ join()

template<typename CharT , typename ValueT , typename AllocatorT , template< typename T, class A > class ContainerT>

std::basic_string<CharT> rcpputils::join	(	const ContainerT< ValueT, AllocatorT > &	container,
		const CharT *	delim
	)

Join values in a container turned into strings by a given delimiter.

Parameters

[in]	container	is a collection of values to be turned into string and joined.
[in]	delim	is a delimiter to join values turned into strings.

Template Parameters

CharT	is the string character type.
ValueT	is the container value type.
AllocatorT	is the container allocator type.
ContainerT	is the container template type.

Returns: joined string

◆ get_executable_name()

std::string rcpputils::get_executable_name ( )

Retrieve the current executable name.

This function portably retrieves the current program name and returns a copy of it.

This function is thread-safe.

Returns: The program name.

Exceptions

std::runtime_error on error

◆ get_platform_library_name()

std::string rcpputils::get_platform_library_name	(	std::string	library_name,
		bool	debug = `false`
	)

Get the platform specific library name.

The maximum file name size is 1024 characters, if the input library_name is bigger than this value then the method throws an exception.

Parameters

[in]	library_name	library base name (without prefix and extension)
[in]	debug	if true the library will return a debug library name, otherwise it returns a normal library path

Returns: platform specific library name

Exceptions

std::runtime_error if it's not able to create the library name

◆ split() [1/2]

template<class InsertIterator , typename std::enable_if< std::is_same< InsertIterator &, decltype(std::declval< InsertIterator >().operator=(std::declval< std::string >()))>::value , ::type * = nullptr>

void rcpputils::split	(	const std::string &	input,
		char	delim,
		InsertIterator &	it,
		bool	skip_empty = `false`
	)

Split a specified input into tokens using a delimiter and a type erased insert iterator.

The returned vector will contain the tokens split from the input

Parameters

[in]	input	the input string to be split
[in]	delim	the delimiter used to split the input string
[in]	it	iterator pointing to a storage container
[in]	skip_empty	remove empty strings from the return vector

◆ split() [2/2]

std::vector<std::string> rcpputils::split	(	const std::string &	input,
		char	delim,
		bool	skip_empty = `false`
	)

inline

Split a specified input into tokens using a delimiter.

The returned vector will contain the tokens split from the input

Parameters

[in]	input	the input string to be split
[in]	delim	the delimiter used to split the input string
[in]	skip_empty	remove empty strings from the return vector

Returns: A vector of tokens.
