String

Let s be a variable whose content is a object of type String, s of type String supports the following public methods:

  • s.len: return string length
  • s.gt(s1): return true if s gt s1 else false, see opts above
  • s.ge(s1): return true if s ge s1 else false
  • s.lt(s1): return true if s lt s1 else false
  • s.le(s1): return true if s le s1 else false
  • s.eq(s1): return true if s eq s1 else false
  • s.ne(s1): return true if s ne s1 else false
  • s.div(num): divide string s by num

Well, this is new let so me give an example "ILovePity".div(3) yields ["ILo", "veP", "ity"]. In case num is greater than s.len then return an array containing s as the single element. also, "Pity".div(3) yields ["Pit", "y"].

  • s.match(/regex/flags): return a matched object, see Match object below
  • s.gmatch(/regex/flags): global match, return an array of Match objects
  • s.sub():
  • s.gsub():
  • s.esub():
  • s.tr(): transliteration s

  • s.uc: uppercase s

  • s.ucfirst: uppercase the first character of s

  • s.lc: lowercase s

  • s.lcfirst: lowercase the first character of s

  • s.fc: foldcase s

  • s.split(delim): split s based on delimiter (delim: string or regex) which is a regex

  • s.cmp(s1): cmp s with s1: s eq s1 yield 0, s lt s1 yields -1, s gt s1 yield 1

  • s.mul(num): multiply s by num, just like the x operator

  • s.append(s1), s.concat(s1): append s1 to s

  • s.prepend(s1): prepend s1 to s

  • s.first(num): return the first num characters of s

  • s.last(num): return the last num characters of s

  • s.char(pos): return character at position pos, NB: zero indexed.

  • s.wordcase: word case s, example "i love afRica".wordcase yield "I Love Africa"

  • s.capitalize(X): capitalize s

  • s.chop(): (From Perl) remove the last character of s and return it

  • s.pop(): remove the last character from s and return the rest

  • s.chomp(): (From Perl) remove trailing new lines

  • s.bin(): coerce s into a number and return it in base 2

  • s.oct(): coerce s into a number and return it in base 8

  • s.hex(): ..... s into ... and in base 16

  • s.crypt(): crypt s, crypt from the C standard library

  • s.decode_base64(): base64 decode s

  • s.encode_base65(): base64 encode s

  • s.md5():

  • s.sha():

  • s.clear(): set s to an empty string

  • s.substr(offset, len): NB: inclusive

  • s.join([s1, s2, ...]): join strings in argument to s

  • s.slice(start, end): negative numbers mean relative to the end of s, since s.char(-1) is s.char(s.len - 1); NB: inclusive

  • s.insert(string, pos, [len]): insert at pos if len is 0 else replace len chars with s1 starting from pos

  • s.index:

  • s.rindex:

  • s.ord:

  • s.reverse:

  • s.print: print without new line

  • s.printf: printf ...

  • s.sprintf: sprintf ...

  • s.say: print with new line

  • s.printlnf: printf with new line

  • s.sprintflnf: sprintf with new line

  • s.is_empty: return bool, check if string is empty

  • s.is_lowercase: ...

  • s.is_uppercase: ...

  • s.is_ascii: ...

  • s.is_space: ...

  • s.is_word: ...

  • s.is_punct: ...

  • s.is_alpha: ...
