Terminology

[RogerAlsing]

This is not really a GP question more of a parsing question.

I'm currently reading the "Red dragon book" (Compiler techniques,
principles..)

I just want to get my head straight when it comes to the word "lexeme"

is the lexeme the actual "content" of a token?

pseudo:

<for> = for | für | foo

if I find a token containing any of the above words, the token would
be a "for" token and the "lexeme" of that token would be "for" , "für"
or "foo" ?

Have I got it right in that case?


(No academic background in the field so I just want to connect my own
made up words to the actual real words :-))

You have it right, it's the text bits:

"The Lexeme is the block of text corresponding to the token"
