String Methods

String methods return strings

• $len(string) -> n string
• $len(array) -> n string (@mmstick)
• $len_bytes(string) -> n string
• $join(array) -> string
• $find(string, string) -> n string
• $starts_with(string, string) -> 0/1 string (@mmstick)
• $ends_with(string, string) -> 0/1 string (@mmstick)
• $contains(string, string) -> 0/1 string (@mmstick)
• $replace(string, string) -> string (@mmstick)
• $replacen(string, string) -> string (@mmstick)
• $to_lowercase(string) -> string (@pithonsmear)
• $to_uppercase(string) -> string (@pithonsmear)
• $repeat(string, n) -> string (@mmstick)
• $extension(filepath) -> string (@pithonsmear)
• $basename(filepath) -> string (@pithonsmear)
• $parent(filepath) -> string (@pithonsmear)
• $filename(filepath) -> string (@pithonsmear)
• $or(string, expr) -> string
  • If the given string does not exist, use the given expression
• $reverse(string) -> string (@pithonsmear)
• $fold(array, string) -> string
  • Apply a reduce/fold function to an array
  • The supplied string should name a command to apply to the array
• $open(string) -> string
  • Open a file and buffer the entire file into memory
• $regex_replace(string, string)
  • Same as $replace(), but the pattern is a regex expression

Array Methods

Array methods return arrays

• @split(string, opt) -> array
• @bytes(string) -> array
• @chars(string) -> array
• @graphemes(string) -> array
• @reverse(array) -> array
• @lines(string) -> array
  • Split a given string by newlines
• @filter(array, string) -> array
  • Apply a filter command to each element in the array
  • Exit status determines which values to filter
  • @filter(array, x => matches $x '([F])\w+')
• @map(array, string) -> array
  • Apply a command to each element in the array
  • Output of the command is the new value for that index
  • @map(array, x => calc $x + $x)
• @open(array, opt) -> array
  • If no pattern string is supplied, split the file by newlines
• @split_at(string, n) -> [string, string]
  • Splits a string into a two-element array; Rust's std
• @split_args(string)
  • Provides an interface for the ArgumentSplitter functionality in the shell.
