Regular Expressions

Function	Description	Meta
regex.find_all_string_submatch_n	output := regex.find_all_string_submatch_n(pattern, value, number) Returns all successive matches of the expression. Arguments: pattern (string) regular expression value (string) string to match number (number) number of matches to return; -1 means all matches Returns: output (array[array[string]]) array of all matches	Wasm
regex.find_n	output := regex.find_n(pattern, value, number) Returns the specified number of matches when matching the input against the pattern. Arguments: pattern (string) regular expression value (string) string to match number (number) number of matches to return, if -1, returns all matches Returns: output (array[string]) collected matches	SDK-dependent
regex.globs_match	result := regex.globs_match(glob1, glob2) Checks if the intersection of two glob-style regular expressions matches a non-empty set of non-empty strings. The set of regex symbols is limited for this builtin: only ., *, +, [, -, ] and \ are treated as special symbols. Arguments: glob1 (string) first glob-style regular expression glob2 (string) second glob-style regular expression Returns: result (boolean) true if the intersection of glob1 and glob2 matches a non-empty set of non-empty strings	SDK-dependent
regex.is_valid	result := regex.is_valid(pattern) Checks if a string is a valid regular expression: the detailed syntax for patterns is defined by https://github.com/google/re2/wiki/Syntax. Arguments: pattern (string) regular expression Returns: result (boolean) true if pattern is a valid regular expression	v0.23.0 Wasm
regex.match	result := regex.match(pattern, value) Matches a string against a regular expression. Arguments: pattern (string) regular expression value (string) value to match against pattern Returns: result (boolean) true if value matches pattern	v0.23.0 Wasm
regex.replace	output := regex.replace(s, pattern, value) Find and replaces the text using the regular expression pattern. Arguments: s (string) string being processed pattern (string) regex pattern to be applied value (string) regex value Returns: output (string) string with replaced substrings	v0.45.0 SDK-dependent
regex.split	output := regex.split(pattern, value) Splits the input string by the occurrences of the given pattern. Arguments: pattern (string) regular expression value (string) string to match Returns: output (array[string]) the parts obtained by splitting value	SDK-dependent
regex.template_match	result := regex.template_match(template, value, delimiter_start, delimiter_end) Matches a string against a pattern, where there pattern may be glob-like Arguments: template (string) template expression containing 0..n regular expressions value (string) string to match delimiter_start (string) start delimiter of the regular expression in template delimiter_end (string) end delimiter of the regular expression in template Returns: result (boolean) true if value matches the template	SDK-dependent
