Read token attributes?

[abrasat]

When iterating the tokens generated by the tokenizer, is it possible to check if any TokenAttribute (category, example or description) is set, and, if yes, to get their values ? It would be also interesting to be able to check directly if the token list contains any token from a certain category.

Hi - yes, the token list is just a list of tokens that can be iterated over/processed using foreach, Linq etc. - can you send more details/pseudocode if this doesn't help? Cheers!

Hi,
Thx for the reply.
For instance these would be some tokens

  [Token(Category = "placeholder", Example = "%1")]
  Placeholder1,
  [Token(Category = "placeholder", Example = "%2")]
  Placeholder2,
  [Token(Category = "placeholder", Example = "%3")]
  Placeholder3,
  [Token(Category = "comment", Example = "//")]
  Comment1,
  [Token(Category = "comment", Example = "///")]
  Comment2,
  [Token(Category = "assignment", Example = ":=")]
  Assign,
  [Token(Example = "(")]
  LeftParen,
  [Token(Example = ")")]
  RightParen,
  [Token(Example = ",")]
  Comma,

And these would be some strings to tokenize and parse

var str1 = "#this is a comment line";

var str2 = "var a := b";

var str3 = "printf("Hello %1")"

For instance, it should be checked if a string to parse contains tokens from the "placeholder" category

Thanks for the follow-up. No, category information isn't exposed right now - you'd need to look it up manually based on Token<T>.Kind.

Ok, thanks
