ORACLE TODO
===========
General
=======
Save unsaved editor buffers into an archive and provide that to the
tools, which should act as if they were saved.
Include complete pos/end information Serial output.
But beware that sometimes a single token (e.g. +) is more helpful
than the pos/end of the containing expression (e.g. x \n + \n y).
Specific queries
================
callers, callees
Use a type-based (e.g. RTA) callgraph when a callers/callees query is
outside the analysis scope.
implements
Make it require that the selection is a type, and show only the
implements relation as it applies to that type.
definition, referrers
definition: Make it work with qualified identifiers (SelectorExpr) too.
references: Make it work on things that are implicit idents, like
import specs, perhaps?
what
Report def/ref info if available.
Editors could use it to highlight all idents of the same local var.
More tests.
pointsto
When invoked on a function Ident, we get an error.
When invoked on a named return parameter, we get an error.
describe
When invoked on a var, we want to see the type and its methods.
Split "show type" and "describe syntax" into separate commands?
peers
Permit querying from a makechan, for...range, or reflective op.
Report aliasing reflect.{Send,Recv,Close} and close() operations.
New queries
"updaters": show all statements that may update the selected lvalue
(local, global, field, etc).
"creators": show all places where an object of type T is created
(&T{}, var t T, new(T), new(struct{array [3]T}), etc.
(Useful for datatypes whose zero value is not safe)
Editor-specific
===============
Add support for "what" to .el; clean up.
Emacs: use JSON to get the raw information from the oracle. Don't
open an editor buffer for simpler queries, just jump to the result
and/or display it in the modeline.
Emacs: go-root-and-paths depends on the current buffer, so be sure to
call it from within the source file, not the *go-oracle* buffer:
the user may have switched workspaces and the oracle should run in
the new one.
