17:15 mmk1: jonrafkind if you have code can you give me pls
17:15 yoklov: whoa dejavu
17:15 mmk1: it's too important for me Oxryly
17:15 yoklov: Oxryly: you use it to build tools?
17:16 yoklov: and i agree about the development ecosystem, racket et al is remarkably full-featured
17:18 Oxryly: mmk1: you probably won't find much help here if this is an assignment for you to implement
17:18 Oxryly: yoklov: yeah we've used it in a tools that compiles data for the game runtime (and some of that data is script)
17:19 jonrafkind: Oxryly, do you use printf to debug racket programs?
17:19 Oxryly: mmk1: I should say, ask specific questions if you want help.
17:19 mmk1: yes I know Oxryly I have to implement but tomorrow I must send to teacher with e-mail I haven't made code yet
17:20 Oxryly: jonrafkind: sometimes. mostly we examine pieces of the code at the repl.
17:20 mmk1: Make us a beauty pls :))) Oxryly
17:21 mmk1: jonrafkind : help me pls
17:22 Oxryly: jonrafkind: and we've used the errortrace lib to narrow things down sometimes.  our debugging approach is fairly haphazard.
17:22 Oxryly: mmk1: ask a specific question
17:23 jonrafkind: racket needs a real debugger..
17:23 mmk1: okey how I make coordinate and how ı make bomb?
17:24 stamourv: jonrafkind: Then write one! :D
17:24 jonrafkind: yea.. ive had 2/3 false starts in the past
17:24 jonrafkind: im getting ready for attempt #4!
17:24 Oxryly: jonrafkind: yeah. seems like a big task.
17:24 stamourv: Great!
17:25 stamourv: Oxryly: IIRC, most of the pieces are already there.
