10:07 <hdbbdh> A easy list-char program: http://pasterack.org/pastes/26095 and I have three questions: 1. Is there a way to merge the "display" function into the else-expr of if; 2. If 1. is OK, whether the solution will maintian tail recursion optimization; 3. Is there a better way to perform this task in tail-recursion style?

10:07 <hdbbdh> Any help is greatly appreciated

10:10 <bremner> hdbbdh: you can use a (begin ...) expression where you want a seqence of expressions for else-expr

10:12 <bremner> (if ... (void) ... ) can be replaced with (unless ... ...)

10:14 <hdbbdh> Alright, I haven't yet learnt (begin ...) lol

10:14 <hdbbdh> So if I use begin ..., will it maintian tail recursion optimization?

10:14 <bremner> yes, if the recursion is the last expression in the begin. _maybe_ also if not

10:15 <bremner> stepping in the debugger can help check

10:17 <hdbbdh> Is debugger available in VS Code?

10:17 <hdbbdh> Or I should use Drracket instead?

10:19 <bremner> ah, I meant in DrRacket. I don't know about VSCode

10:20 <bremner> drracket can revert files if they are editted externally, so you can use it with another editor (I do this with emacs)

10:21 <hdbbdh> I see. Thank you very much.

10:23 <bremner> welcome

14:34 <migas> Hi. I am trying to create some nice TUI app but:

14:34 <migas> charterm is black and white

14:34 <migas> racket-ncurses in not maintained anymore

14:34 <migas> ansi-colors is just to use some text colors

14:34 <migas> what do you recommend?
