Ragnar, thanks for your kind words; I'm glad you're finding kern fun and useful.
The lexer module has parsers that take care of whitespace, and conveniences like parens, braces, comma-sep (and others) that shorten things. You might start with the namespace blancas.kern.lexer.basic and use similar functions as core (but without the star) like sym and token that handle whitespace (these functions parse and then consume any whitespace until the next char). Using some of the functions from that namespace, lines 93-102 may come down to: (def ruby-attributes (braces (comma-sep ruby-attr-pair))) Similarly, lines 64-69 could be: (def html-attributes (parens (many html-attr-pair))) just surround the values with (lexeme) to ignore whitespace: the defs for html-name, html-value, ruby-name, etc: (def html-name (lexeme (<|> ...))) That would reduce the checks for spaces in your (bind) sequences. Just experiment with these ideas and see if it gets simpler. Feel free to ask me any more questions.
