20:11 <mort> hey, is it possible to get raco to install a package to a particular directory?

20:11 <mort> so that it doesn't touch any other directories

20:13 littlebobeep has joined #racket

20:16 morte_ has joined #racket

20:16 <bremner> mort: you can specify --scope-dir. Does that do what you want?

20:17 <mort> I didn't quite get what it was supposed to do, it didn't seem to actually put anything which looked like a package in the destination dir

20:17 gproto23 has joined #racket

20:18 <mort> it just put a links.rktd and a pkgs.rktd file in the dir

20:19 <bremner> hmm. Not in my case.

20:20 <bremner> You might have to call "raco setup --pkgs foo" afterwards

20:20 <samth> mort: did you specify a directory as the package to install?

20:20 <mort> samth: yes

20:20 <samth> then it linked that directory rather than copying it

20:21 <mort> I tried to pass --copy but that didn't seem to do anything

22:01 Beginner has joined #racket

22:06 <Beginner> Hello. In DrRacket 8.5 (using BSL, following the textbook How to Design Programs 2e), it states "BSL preserves this precision whenever possible. For example, (/ 4 6) produces the precise fraction 2/3, which DrRacket can render as a proper fraction, an improper fraction, or a mixed decimal". In my DrRacket, I am getting 0.6 (with no indication of

22:06 <Beginner> this being inexact) as output from (/4 6) rather than the precise fraction 2/3. Do you know why my default output is different and how I can get the precise fraction?
