Strings

MarkovAlgorithmLibrary "MarkovAlgorithm" Markov algorithm is a string rewriting system that uses grammar-like rules to operate on strings of symbols. Markov algorithms have been shown to be Turing-complete, which means that they are suitable as a general model of computation and can represent any mathematical expression from its simple notation. ~ wikipedia . reference: en.wikipedia.org rosettacode.org parse(rules, separator)   Parameters:      rules (string)      separator (string)   Returns: - `array _rules`: List of rules. --- Usage: - `parse("|0 -> 0|| 1 -> 0| 0 -> ")` apply(expression, rules)   Aplies rules to a expression.   Parameters:      expression (string) : `string`: Text expression to be formated by the rules.      rules (rule ) : `string`: Rules to apply to expression on a string format to be parsed.   Returns: - `string _result`: Formated expression. --- Usage: - `apply("101", parse("|0 -> 0|| 1 -> 0| 0 -> "))` apply(expression, rules)   Parameters:      expression (string)      rules (string)   Returns: - `string _result`: Formated expression. --- Usage: - `apply("101", parse("|0 -> 0|| 1 -> 0| 0 -> "))` rule   String pair that represents `pattern -> replace`, each rule may be ordinary or terminating.   Fields:      pattern (series string) : Pattern to replace.      replacement (series string) : Replacement patterns.      termination (series bool) : Termination rule.

composite_ticker_cleanerLibrary "composite_ticker_cleaner" Extract a clean symbol from a composite ticker. E.g., (BINANCE:BTCUSD+KRAKEN:BTCUSD)/2 as input will return BTCUSD or BINANCE:BTCUSD composite_ticker_cleaner_extract_first(symbol, keepexchange)   Extract the first symbol out of the supplied string (usually ticker.standard(syminfo.tickerid) )   Parameters:      symbol : string input string to search in      keepexchange : bool (optional) Keep exchange in the returned ticker? By default, we only return the symbol without the exchange.   Returns: first occurrence of a symbol composite_ticker_cleaner_extract_first(keepexchange)   Extract the first symbol out of the current tickerid (as provided by ticker.standard(syminfo.tickerid) )   Parameters:      keepexchange : bool (optional) Keep exchange in the returned ticker? By default, we only return the symbol without the exchange.   Returns: first occurrence of a symbol in the current tickerid This is inspired by the work I did on this indicator: I needed a similar functionality in another script, so instead of duplicating code, I thought generalizing the process in a library could be helpful for me and others, and will be easier to maintain and upgrade with new features if I need to.
