Contact: giodl – Step 1: Tokenize

token Alias = ("A".."Z" | "a".."z")+; Tokens define the “words” of your language Contact: giodl –

Step 2: Parse Contact: giodl –

syntax ContactEntry = "Contact" ":" alias:Alias "-" phone:Phone => Contact { Alias { alias }, Phone { phone } }; Syntax defines the “sentences” of your language Contact: giodl –

Remember interleave? Contact: giodl – interleave Ignorable = " " | "\n" | "\r“;

Shape the data… Contact: giodl – syntax ContactEntry = "Contact" ":" alias:Alias "-" phone:Phone => Contact { Alias { alias }, Phone { phone } };

Contact: giodl – syntax ContactEntry = "Contact" ":" alias:Alias "-" phone:Phone => Contact { Alias { alias }, Phone { phone } }; Contact AliasPhone giodl

Contact AliasPhone giodl syntax ContactEntry = "Contact" ":" alias:Alias "-" phone:Phone => Contact { Alias { alias }, Phone { phone } };
