<countvajhula> i came across this, the "medic debugger": https://docs.racket-lang.org/medic/index.html
<countvajhula>
<countvajhula> does anyone use this in their workflow?
<countvajhula> seems like an interesting approach
<countvajhula> "The Medic debugger is a debugging tool that incorporates a metaprogramming language to describe the task of debugging and a full-featured tracing library to enhance the traditional debugging technique of inserting print-like expressions into the source program."
<countvajhula> i like the idea of enhancing an existing behavior (sprinkling print statements) so that it's more useful
badkins has joined #racket
Fare has joined #racket
<countvajhula> or rather, providing an equivalent and more useful alternative to sprinkling print statements
<samth> countvajhula: medic is a research project (the author has now graduated), I don't know if it's seen much use in practice
<countvajhula> i see

<countvajhula> i've definitely wished for better debugging tools in racket
<countvajhula> i've tried errortrace, but it's only proven useful on a couple of occasions
rj_ has joined #racket
<countvajhula> racket/trace seems kind of fringe too
<countvajhula> i think a full-fledged debugger would be wonderful to have, like gdb or python's pdb
<countvajhula> (in python i'm a big fan of `pudb`, a terminal-based GUI frontend to pdb)
<countvajhula> and seems like we could in theory implement it well with continuations
<countvajhula> like maybe wrap every expression in a continuation at the compile stage, kind of like lazy evaluation does, wrapping each expression with `delay`
<countvajhula> and then at runtime we could have access to the full runtime context at each step of evaluation
<samth> countvajhula: the debugger in drracket does something like that. it would be interested to put a text ui frontend on that
<countvajhula> oh nice, that would be amazing
<countvajhula> this is pudb, btw: https://github.com/inducer/pudb
<countvajhula> samth: is there a feature request I can make somewhere for that? i would be happy to record a github issue as a focal point
<samth> countvajhula: i don't think that
<samth> 's the sort of thing that's useful as a "feature request"
endformationage has joined #racket
<countvajhula> samth: you mean because it's not specifically drracket related?
<samth> no, I mean that "write a debugger" isn't a useful feature request -- it's a big project that if someone wanted to work on it would be great, but opening a github issue isn't a useful part of that process

<countvajhula> i was referring to your comment about drracket already having such a debugger, that could potentially be exposed via a terminal UI

<Fernando-Basso[m> Could it be that the book is missing the definitionis of ‘f’ and ‘ff’? Or I am simply overlooking something?
<Fernando-Basso[m> Ah, “f from the previous section”.
