#str
Functions to manipulate character strings.
str:before(target, sub)
Evaluates target and sub as strings, then returns the substring of target before the first occurrence of sub. If sub cannot be found, then this function returns target.
str:after:sub(target)
Evaluates target as a string, then returns the substring of target after the first occurrence of sub. If sub cannot be found, then this function returns target.
str:basename(path)
Treats path as a file path and returns the last element of path.
str:after(target, sub)
Evaluates target and sub as strings, then returns the substring of target after the first occurrence of sub. If sub cannot be found, then this function returns target.
str:before:sub(target)
Evaluates target as a string, then returns the substring of target before the first occurrence of sub. If sub cannot be found, then this function returns target.
str:cmp(a, b)
Evaluates a and b as strings, then compares the results. This function returns -1, 0 or 1 when a is lower, equal or greater than b.
str:diacritics(s)
Evaluates s as a string, then returns the result with diacritics removed.
str:equalsIgnoreCase(a, b)
Evaluates a and b as strings, then returns either the two strings are equal ignoring the character case.
str:hash(s)
Returns a hash code computed from s.
str:index(s, target)
Evaluates s and target as strings, then returns the number of characters in s before the first occurrence of target in s. If there is no occurrence of target in s, then this function returns -1.
str:join(items, string, separator)
Evaluates items as a list of elements and separator as a string. Then for each element of items, this function evaluates string as a string and returns a concatenation of the results seperated with separator
str:join:separator(items, string)
Evaluates items as a list of elements, then for each element of items, this function evaluates string as a string and returns a concatenation of the results seperated with separator
str:join(items, string)
Evaluates items as a list of elements, then for each element of items, this function evaluates string as a string and returns a concatenation of the results seperated with a single whitespace.
str:len(target)
Evaluates target as a string, then returns the number of characters in the result.
str:levenshtein(a, b)
Evaluates a and b as strings, then returns the edit distance between the results.
str:levenshteinSimilar(a, b, d)
Evaluates a and b as strings and d as a float, then returns either the edit distance between a and b is lower or equal than d. This function is useful for approximate string matching.
str:lower(target)
Evaluates target as a string and returns it with all characters converted to lower case.
str:normalizeSpace(s)
Evaluates s as a string, then returns the result with leading and trailing whitespace characters removed, and sequences of whitespaces characters replaced with a single space character.
str:padl(s, n)
Forces s to length n. If shorter, then this function adds as many spaces necessary at the beginning. If longer, then this function truncates s.
str:padl:filler(s, n)
Forces s to length n. If shorter, then this function adds as many filler necessary at the beginning. If longer, then this function truncates s.
str:padr(s, n)
Forces s to length n. If shorter, then this function adds as many spaces necessary at the end. If longer, then this function truncates s.
str:padr:filler(s, n)
Forces s to length n. If shorter, then this function adds as many filler necessary at the end. If longer, then this function truncates s.
str:regrp(s, re, n)
Compiles re as a regular expression and searches in s. This function returns the n capturing group of the regular expression.
str:replace(target, search, replace)
Evaluates target, search and replace as strings, then returns target with all non-overlapping occurrences of search substituted with replace.
str:rindex(s, target)
Evaluates s and target as strings, then returns the number of characters in s after the last occurrence of target in s. If there is no occurrence of target in s, then this function returns -1.
str:seds(target, pattern, replace)
Evaluates target, pattern and replace as strings, then interprets pattern as a Java Regular Expression. This function returns target with all non-overlapping matches of pattern substituted with replace.
str:split:separator:feature(target)
Evaluate target as a string, then splits it by the first character of separator. The adds each string into the context feature named feature. Feature modification must be allowed.
str:sub(target, from, to)
Evaluates target as a string, from and to as integers, then returns the subsequence of target between indexes from (inclusive) and to (exclusive). Indexes start at 0.
str:sub(target, from)
Evaluates target as a string and from as an integer, then returns the subsequence of target from index from (inclusive) and to (exclusive)to its end. Indexes start at 0.
str:trim(s)
Evaluates s as a string, then returns the result with leading and trailing whitespace characters removed.
str:upper(target)
Evaluates target as a string and returns it with all characters converted to upper case.
