Hi All,<div><br></div><div>The experience of implementing a #lang based language have been pleasant.</div><div>It is impressing just how painless the macro/module system and DrRacket</div><div>works together.</div><div><br>
</div><div>So far my custom language has:</div><div> - parser with source location</div><div> - syntax errors with source location</div><div> - color lexer to color source in DrRacket</div><div> - custom repl</div><div>
<br></div><div>However there is one thing missing. After clicking the check syntax</div><div>button in DrRacket I do not get any arrows showing bindings.</div><div>Obviously I must have missed something, but what?</div><div>
Is something required to turn on the arrows?</div><div><br></div><div>I have looked some at the algol60 and datalog languages, but I can't</div><div>spot what I am missing.</div><div><br></div><div>Is it required to register the language as a tool?</div>
