Re: [racket-users] Current state of racket2 planning?

Matthew wrote a long email on Wednesday with about the current state,
although the subject was "Rhombus Project Plan" so that may have been why
you missed it.

[racket-users] Current state of racket2 planning?

2019-10-04 Thread David Storrs
The racket2 discussion dropped off my radar a while ago but I got some
spoons back and thought I'd check in again. Where should I look to see the
ongoing discussion / current state?

Sidebar: I read the Honu paper... Is the current plan still "programmer
writes C-ish code and then, behind the scenes,  Honu-ish enforestation
expander turns it back into Lisp-ish code so that the engine can run it"?

[racket-users] Does Racket have something similar to IPython.embed() for debugging?

2019-10-04 Thread Marc Kaufmann
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
