partial revert of 3d3ea61d53, which introduced core names by completing
an unimplemented feature that was already present in hoon.hoon. we've
decided to remove this for the initial launch since it violates the
principle of least surprise for the name of a core to end up in its
$garb and yet only be used for doccords, as opposed to something like a
wing resolution. it was also confusing that this only worked for |% and
|@.
this breaks two of the tests for the dprint library, which have been
commented out. these tests ought to be restored once dprint is rewritten
in order to implement a different way to refer to cores not built by arms
this constitutes a pretty major rework of how whitespace is handled in
hoon in order to change the doccords syntax from :> and :< to ::.
in summary: throughout the hoon parser (+vast) many instances of +gap
have been replaced by +jump, which first tries to remove whitespace (+leap)
until it arrives at something that can be parsed as a prefix
doccord (+apex:docs:vast). if it does not encounter a doccord, it
instead uses +gap as normal.
if you follow along with the parser, you will notice that every time
jump is called, it then tries to call +apex:docs via +scye or +seam. if
apex:docs succeeds, it will end up consuming a newline at the end,
hiding the fact that there was valid whitespace from the parser. thus
+apex:docs then inserts a newline after successfully parsing a prefix
doccord, which will then be consumed by a subsequent invocation of +gap,
ensuring that there was proper whitespace if the doccord would have been
consumed by +gap instead of +leap.
there are a few other changes:
+hint in the compiler throws out doccords attached to %noun types. this
was already the behavior before doccords, and the change was made before
i understood what i was doing.
similarly for commenting out the %note case in +open:ap - this was an
earlier mistake
postfix comments for chapters are now enabled.
+expx was unused and removed in order to be rid of the
convention-defying +exp1. other unused +ex(p/q)* were commented out.
arms that handle batch comments (+glow and +whap) were refactored
+toad, which was used to change between tall and wide form, tries to
+jump before +gap. since +jump is ;~(pose leap:docs gap), i would have
thought that just using +jump there would be fine, but it fails for some
reason.
some parsers built with |@ were rewritten to use |*
|$ was made so that any doccords put on the spec are converted into hoon
doccords on the $ arm. it wouldn't compile otherwise. there's probably a
more principled way to do this but it works fine for now.
