Also combined expansion of in-generator for both expression and sequence
contexts, and made a number of places that were handling arity dynamically
to handle it statically instead.
Adds `--from-dir' and `--from-install' flags to select the interpretation
of the argument as a directory or as the name of an installed package.
Relevant to PR 13669
Adds `--as-is' (the default), `--source', and `--binary' flags to
select a pruning mode.
The `raco setup' tool recognizes a `rendered-scribblings' specification
in "info.rkt" to trigger moving rendered documentation into place,
registering its tags in the cross-reference database, and fixing up
references to "local-redirect.js"; the presence of a "synced.rktd"
indicates when those fixups have been performed (since, if the package
is installed in a user-specific scope, the documentation doesn't actually
move anywhere). Finally, "out<n>.sxref" needs to report paths relative to
the documentation's directory, and then the relative-directory references
need to be suitably resolved at derserialization; some support for such
relative paths was in place, but it wasn't quite general enough before.
Even though "info.rkt" files are in collections, `raco setup'
treats them in a directory-specific way --- and that's necessary
for specifying things like `compile-omit-files' in a collection
splice.
Make drest a list instead of a pair, replace an int-err with a match error
which has source location, and remove static name for rest argument in error
case.
When starting a thread, the thread was created and partially
initialized before trying to get a name for the thread from the given
thunk, but getting a name for the thunk could trigger scheduler
descisions, which could get confused by the partially initialized
thread.
the package installer
and make DrRacket have two separate menu items, one for installing a package
(which now looks simpler again) and one for doing all of the things you can
currently do with the package system in a GUI
