tinkr (development version)

  • removed dependency on stringr in favor of base R functions wrapped in internal functions with a stringr-like interface (#88).
  • unescaped square braces from the source code can now make the roundtrip without extra markup. This is implemented in a new default parameter for to_xml() called unescaped = TRUE, which indicates that you would like unescaped square braces to remain unescaped (#78).
  • New protect_curly() function will add a curly='true' attribute to text wrapped in curly braces (‘{’, ‘}’) to allow parsing of the XML for sending to external APIs. This function will also parse alt text and place it in an attribute.
  • New $protect_curly() method implements protect_curly() on yarn objects
  • Relative link anchor keys will no longer have characters escaped (#85).
