s-exp library not usable

[shriram]

Consider this:

> import s-exp as S
> sl = S.read-s-exp("(1 2)")
> S.is-s-list(sl)
true
> sl
s-list([list: s-num(1), s-num(2)])

Great. Now let's try to get the list out of the s-list structure. (You are not allowed to grep the Pyret source code, as I just did.)

If it helps, the documentation is here:

http://www.pyret.org/docs//latest/s-exp.html

Anything beyond the most rudimentary testing (hopefully the tests aren't only those shown in the documentation…) would reveal this problem.

Those docs link to http://www.pyret.org/docs//latest/s-exp-structs.html#%28part._s-exp-structs_.S-.Exp%29, which describes the S-Exp datatype, which can be manipulated in all the usual ways. On Sun, Oct 30, 2016 at 10:28 PM Shriram Krishnamurthi < notifications@github.com> wrote:

Surely you aren't telling me that this is easy to figure out? I don't even see why we have two different libraries here. The only reference is in a blue word that is the same name as the current library (i.e., hardly a word you would expect to click on). And there are no examples to show how to use this part of the library, which surely is the user's intent most of the time…
