template<typename T >

std::string utils::bullet_list	(	const T &	v,

Generates a new string containing a bullet list.

List items are preceded by the indentation blanks, a bullet string and another blank; all but the last item are followed by a newline.

Parameters

v	A container with elements.
indent	Number of indentation blanks.
bullet	The leading bullet string.

◆ contains()

template<typename Container , typename Value >

bool utils::contains	(	const Container &	container,
		const Value &	value
	)

inline

Returns true iff value is found in container.

This should work whenever Container "looks like" an STL container of Values. Normally this uses std::find(), but a simulated partial template specialization exists when Value is Container::key_type. In this case, Container is assumed an associative container, and the member function find() is used.

std::string utils::indent	(	const std::string &	string,
		std::size_t	indent_size = `4`

Splits a string based on two separators into a map.

Major: the separator between elements of the map Minor: the separator between keys and values in one element

For example, the string 'a:b,c:d,e:f' would be parsed into: a => b c => d e => f

◆ might_contain_variables()

bool utils::might_contain_variables ( const std::string & str )

inline

Determines if a string might contain variables to interpolate.

This can allow one to skip future interpolations (plural – if there is only one interpolation, the savings are not worth this check). In this spirit, precision is sacrificed in the name of efficiency; the check is quick and allows false positives, but there are no false negatives. (A false negative would lead to incorrect behavior, whereas a false positive leads to merely inefficient behavior.) In practice, false positives should be uncommon enough to not worry about.

◆ parenthetical_split()

		const char	separator = `0`,
		const std::string &	left = `"("`,
		const std::string &	right = `")"`,
		const int	flags = `REMOVE_EMPTY\|STRIP_SPACES`
	)

Splits a string based either on a separator, except then the text appears within specified parenthesis.

If the separator is "0" (default), it splits a string into an odd number of parts:

The part before the first '(',
the part between the first '('
and the matching right ')', etc ... and the remainder of the string.

Note that one can use the same character for both the left and right parenthesis, which usually makes the most sense for this function.

Note that this will find the first matching char in the left string and match against the corresponding char in the right string. A correctly processed string should return a vector with an odd number of elements. Empty elements are never removed as they are placeholders, hence REMOVE EMPTY only works for the separator split.

This function is identical to split(), except it does not split when it otherwise would if the previous character was identical to the parameter 'quote' (i.e.

it does not split quoted commas). This method was added to make it possible to quote user input, particularly so commas in user input would not cause visual problems in menus.

Parameters

[in]	val	A (comma-)separated string.
[in]	c	The separator character (usually a comma).
[in]	flags	Flags controlling how the split is done. This is a bit field with two settings (both on by default): REMOVE_EMPTY causes empty pieces to be skipped/removed. STRIP_SPACES causes the leading and trailing spaces of each piece to be ignored/stripped.

◆ square_parenthetical_split()

std::vector< std::string > utils::square_parenthetical_split	(	const std::string &	val,
		const char	separator = `','`,
		const std::string &	left = `"(["`,
		const std::string &	right = `")]"`,
		const int	flags = `REMOVE_EMPTY\|STRIP_SPACES`
	)

Similar to parenthetical_split, but also expands embedded square brackets.

Notes:

The Separator must be specified and number of entries in each square bracket must match in each section.
Leading zeros are preserved if specified between square brackets.
An asterisk as in [a*n] indicates to expand 'a' n times

This is useful for expanding animation WML code.

Examples:

INPUT: ("a[1-3](1,[5,6,7]),b[8,9]", ",") RETURNS: {"a1(1,5)", "a2(1,6)", "a3(1,7)", "b8", "b9"}

INPUT: ("abc[07-10]") RETURNS: {"abc07", "abc08", "abc09", "abc10"}

INPUT: ("a[1,2]b[3-4]:c[5,6]") RETURNS: {"a1b3:c5", "a2b4:c6"}

INPUT: ("abc[3,1].png") RETURNS: {"abc3.png", "abc2.png", "abc1.png"}

INPUT: ("abc[de,xyz]") RETURNS: {"abcde", "abcxyz"}

◆ vertical_split()

std::pair< string_view, string_view > utils::vertical_split ( const std::string & val )

Splits a string into two parts as evenly as possible based on lines.

For example, if the string contains 3288 lines, then both parts will be 1644 lines long.

The line separator in between won't be in either of the parts the function returns.

Because this function is intended for extremely long strings (kilobytes long), it returns string_views for performance.
