The new flags can be used to make an embedded module's name
predicatable, which is useful for making a deserialization format
stable (i.e., `serializable-struct` creates a serializer that uses the
embedded module name). This functionality was already available from
`create-embedding-executable`, but there was no way to reach it via
`raco exe`.
Move different handling of serialized syntax data to the schemify
layer instead of te expander, so that the result of compiling in
machine-independent form is the same for traditional Racket and Racket
CS.
Although `raco dec` cannot yet usefully decompile Racket CS compiled
code, the underlying `zo-parse` and `zo-marshal` functions can now at
least read and re-write that format by just keeping the bytes for the
CS-specific part, and it can also now rouind-trip the machine- and
VM-independent format.
Lots of plumbling was in place to preserve the source name (instead of
the symbol generated to avoid collisions for macro-introduced
definitions), but some small pieces were missing.
Closes#2288
When a stand-alone executable created by `raco exe` needs to load
modules that start with a `#lang` line, there have been various
obstacles to adding the right run-time support via `++lib`. The
`++lang` flag addresses those problems and makes it easy to indicate
that enough should be embedded to support loading modules with a
specified language.
There are problems in the way that various handlers interact for the
"lang/reader.rkt" versus `(submod "." reader)` search path that
converts a language name to a reader. To accomodate the search in a
standalone executable (that does not provide access to collections in
general), the module name resolver must refrain from raising an
exception for a non-existent submodule path that refers to a
non-existent collection.
Creating an executable with embedded DLLs means that the executable
can be truly stand-alone, instead of needing to be kept with its
DLLs in a relative subdirectory.
DLL embedding works by bypassing the OS's LoadLibrary and
GetProcAddress functions, and instead maps the DLL into memory
and performs relocations explicitly. Joachim Bauch's MemoryModule
(Mozilla license) implements those steps.
This commit merges changes that were developed in the "racket7" repo.
See that repo (which is no longer modified) for a more fine-grained
change history.
The commit includes experimental support for running Racket on Chez
Scheme, but that "CS" variant is not built by default.
Although "macOS" is the correct name for Apple's current desktop OS,
we've decided to go with "Mac OS" to cover all of Apple's Unix-like
desktop OS versions. The label "Mac OS" is more readable, clear in
context (i.e., unlikely to be confused with the Mac OSes that
proceeded Mac OS X), and as likely to match Apple's future OS names
as anything.
`cext-lib` contains much of the contents of `dynext`, which
is no longer very widely used.
Also moved the implementation of the `mzc` executable
to a more appropriate package.
Also, used `lazy-require` consistently for dynamically
loading implementations.
The range of values used to represent "improper lists"
of length 36 to 65 overlapped with the range of values
used to represent other things.
This bug is the new chapion of the "how did we not hit that
earlier?" category. The bug was introduced around v300, at
the latest.
