Function Documentation

do_interpolation()

static std::string do_interpolation ( const std::string &  str, const variable_set &  set  )

Definition at line 66 of file string_utils.cpp.

edit_distance_approx()

int edit_distance_approx	(	const std::string &	str_1,
		const std::string &	str_2
	)

Approximately calculates the distance between two strings.

Inspired in the Levenshtein distance, but made simpler to avoid using recursion and wasting resources.

The consequence is that the function gets "lost" after two consecutive differences.

Parameters

str_1	First string to compare
str_2	Second string to compare

vgettext_impl()

std::string vgettext_impl	(	const char *	domain,

Implementation functions for the VGETTEXT and VNGETTEXT macros.
