There is nothing in this commit except for the changes made by
nix-shell -p nixfmt-rfc-style --run "nixfmt ."
If this has mucked up your open branches then sorry about that. You
can probably nixfmt them to match before merging
* [] is now [ ]
* {} is now { }
* commas in arglists go at end of line not beginning
In short, I ran the whole thing through nixfmt-rfc-style but only
accepted about 30% of its changes. I might grow accustomed to more
of it over time
The second parameter is now an options attrset, wherein we will pile
all kinds of cool stuff.
Right now the only cool bit is `mainFunction`, which allows you to
compile a fennel module into a lua script and name the function that
should be executed when the script runs. This makes it easier to
write testable Fennel code, because the test script can require the
module and call stuff in it.
