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have been replaced by +jump, which first tries to remove whitespace (+leap)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.
this refactors the parser for %brcn and %brpt to separate the optional
argument(s) from the required argument(s).
also adds +blab, which allows for a minor refactor of a couple other
arms as well as being used for %brcn and %brpt
this commit replaces the previous intermediate parsing structure, $whit,
with a new one better suited for batch comments and taking into account
that {# %label} syntax is no longer being used anywhere. basically,
this makes it so that all doccords are batch comments, where if they are
preceded by a (list link) then they will try to attach to the given
link (only utilizes first link for now), and a blank link means it will
try to attach to the following hoon or spec
using col as a seperate made it look like a bunch of =<, which doesn't
make sense for e.g. pritning chapters. paths aren't quite right either,
so we don't use +stap, and just want identifiers separated by fas
without any leading fas
changes $whit to have a (unit link) instead of (unit term). this holds
the identifier for where a comment is supposed to go. changes to parsers
in docs:vast to accomodate this.
this only allows for batch comments written for arms within a given
core. someday, the feature should allow you to write comments
virtually anywhere. the (unit link) in $whit should become a (unit (list
link)) to accommodate this
