Option to exlude some characters from being decoded about htmlentities

[gucki]

My current workaround is:

class HTMLEntities
  FLAVORS << "xhtml1_customized"

  MAPPINGS["xhtml1_customized"] = MAPPINGS["xhtml1"].dup
  MAPPINGS["xhtml1_customized"].reject!{ |v| ["lt", "gt", "amp"].include?(v) }
end

And then do HTMLEntities.new("xhtml1_customized").decode(string).

That sounds like a really nice feature. Do you have any ideas about what the interface might ideally look like?

[gucki]

Not really, but probably something really simple like TMLEntities.new("xhtml1").decode(string, :exclude => ["lt", "gt", "amp"])?

👍 That's the only missing thing in this library.
But I would specify the list the other way around, since for a same character you can have multiple encodings HTMLEntities.new.decode(str, exlude: ['<', '>', '&'])

How about a parameter to only decode "safe" codepoints?

The encode method already makes a distinction between "safe" and "unsafe" codepoints. By default, it only encodes unsafe codepoints:

string = "<élan>"
coder.encode(string) # => "&lt;élan&gt;"

The decode method could take a parameter to only decode safe codepoints:

string = "<élan>"
coder.decode(string, :safe) # => "<élan>"
