Avoid printing `(unquote @d)` or `(unsyntax @d)` as `,@d` or `#,@d`,
which would mean `(unquote-splicing @d)` or `(unsyntax-splicing @d)`
to the reader, by adding an extra space before the `@`.
Accessing unsafe functionality through the FFI seemed like a good way
to avoid writing C code, but it made things more complicated instead
of easier, and it interacts badly with a more agressive shift away
from C (such as porting to Chez Scheme). So, add functions to the
primitive `#%unsafe` module, instead.
* Fixed typo in the docs for serialization (serializable-struct/version → serializable-struct/versions)
* Fixed typo in scribble documentation (head pattern → a-pattern)
* Made the order of the argument descriptions match the order of the arguments in the documentation for import and export
An authentic structure type is one whose instances cannot be
impersonated or chaperoned. The intended use of `prop:authentic` is to
annotate a library-private data structure where impersonators are
never needed internally for the data structure, and the declaration
lets the compiler produce less code and fewer branches by omitting
impersonator support.
The blame object passed to a late-neg-proj function will be missing
one party. The missing party is sometimes the negative party and
sometimes the positive party.
In non-cross mode, `-C` needs to go after `-G` and `-X` when setting
up a "bundle" directory to turn into an installer, because that mode
needs to use foreign libraries (such as SQLite) at build time, and it
can use the instances that are being set up for the installer.
Meanwhile, improve the advice for setting `PLAIN_RACKET` to use `-C`
for a cross-platform build mode, even though things tend to work
anyway without it.
Detangle the target and host DLL and library directories by
making `get-lib-search-dirs` and `get-dll-dir` report the
host system's directories, and add `get-cross-lib-search-dirs`
and `get-cross-dll-dir`.
A new `-C`/`--cross` flag causes `racket` to save a host config and
collection directory and make them available via `(find-system-path
'host-{config,collects}-dir)`, while plus `(system-type 'cross)`
reports whether `-C` mode is in effect. Besides making the host paths
available, this change allows a same-platform build to run in
corss-platform mode.
The immediate problem to solve was the creation of Windows installers
on Windows, where recent changes to support 'gui-bin-dir configuration
need a clear distinction between the host Racket and the target Racket
being built, even if they're the same platform. (The "GRacket.exe"
executable didn't work, for example.)
The changes in this commit are more than needed for the immediate
problem, but they naturally build on the necessary `-C` flag, and they
support cross-platform package setup where native libraries are needed
during setup.
Make `log` in `racket/base` optionally accept a second argument.
The second argument is the log `base`. The docs also recommend
`fllogb` when precision is important.
* Error message when base is 1
* Added docs.
* Add tests.
Remove the history annotation on `build-flat-contract` property
about removing the `#:exercise` keyword.
Because the keyword wasn't actually removed from the function,
only from the (incorrect) documentation. So there aren't any
legal programs that depend on the removed keyword argument.
