Hi,
a friend who uses Python mentioned that how he debugs is via `embed()`,
which launches an IPython console at the point it is called with all the
variables that exist at that point being defined, so you can inspect a
bunch without sprinkling prints everywhere.
```{python}
from IPython import embed
a = 30
b = 20
embed() # At this point an IPython console will pop up and one can check
the values of `a` and `b`, then type `exit()` to continue
c = 10
d = 0
embed()
```
I was wondering if Racket has something similar? Sometimes it's not that
useful since I have to figure out the point where things break, but at
other times, it might be quite useful.
Additionally, I came across this tread on racket-users from 2015:
https://groups.google.com/forum/#!searchin/racket-users/inspect$20variable%7Csort:date/racket-users/Jzg7cYCH-GY/nciHFLZkBAAJ
Are there any more up-to-date resources on how to debug in Racket? Thanks
to vim-slime my debugging is already faster (all you emacs people are
probably way ahead thanks to Greg's racket-mode), but it's still incredibly
clunky and slow. (Of course if I used tests and contracts more liberally,
things might be different... but hey, debugging can't be avoided, tests and
contracts can.)
Cheers,
Marc
