restricted through `get-info`, which prunes the environment
variable set before it loads the "info.rkt" file. All
environment variables are pruned except those listed in
`PLT_INFO_ALLOW_VARS` (separated by semicolons).
Related to emina/rosette#17.
Add a hook to `raco setup` to make copies of installed executables,
where the copies start with the configuration or addon directory
of creation time, instead of the default installation or user-specific
path.
Although the same effect can be achived by setting environment
variables such as PLTADDONDIR, tethered executables can be easier
to work with and compose better with other programs.
See also #1206 for some discussion, although this change does
not exactly address the original idea there.
Reduce (unbox (box x)) => x
Extend the reductions for cXr to the unsafe versions, for
example reduce (unsafe-car (cons x y)) => x
Check and save types in unsafe operations
Pass a string to the handler to describe the problem.
Also, fix minor issues (GC registration, contracts and `history`
in docs) and make `pregexp`, etc., report compilation errors as
`pregexp`, etc.
* Add 6.4 version, as this is now the default one to download on the website.
* raco doc <<name>> should use raco docs <<name>>
* raco is now on the PATH, remove warning
* Change `raco setup --check-deps <<name>>` to `raco setup --check-pkg-deps --pkgs <<name>>` (the former seems obsolete).
* Move `raco pkg install --deps search-auto` to the `install:` section, so that it is done before running the tests
* Move `raco pkg install --deps search-auto cover`, to the `after_success section`, since `raco cover` is run there.
* Fixed .travis.yml syntax (wrong indentation for fields under "matrix:")
* Clone https://github.com/greghendershott/travis-racket.git to a separate directory, not a subdirectory of the current package, as this can cause problems (see https://travis-ci.org/jsmaniac/type-expander/jobs/121099218#L824)
POSIX and ANSI specify that char is always 1 byte, and I'm almost
certain that no systems violate this. Regardless, the SIZEOF_CHAR macro
is never used.
Allow `system-type` on non-Windows platforms to run `uname` to get
machine information, even in a sandbox or other contexts with a
limiting secutiry guard.
Check that it works to apply a continuation that shares with
an enclosing continuation, where a runstack overflow happens
between the continuations.
Closes PR 15281
While expanding a module, the root of module-relative references is a
fresh notion of "this module".
After expansion, "this module" is shifted to "an expanded module",
which is a global constant (for top-level modules). When an expanded
module is re-expanded, "an expanded module" is shifted to a fresh
"this module" during re-expansion, and so on.
One problem with this approach is that the shift from "this module" to
"an expanded module" isn't applied to syntax properties --- but
there's some extra trickery to make it work out by mutating "this
module" to make it look like "an expanded module".
Submodule expansion introduces an intermediate "parent of this module"
that wasn't currently covered by the extra trickery, so fix that.
`->i` already supports method contracts (for use wihin `object-contract`,
whose `->i` support is tested, but undocumented), which would make `->im`
possible.
Unfortunately, that support is very incomplete, missing support for using
`this` in contracts, making this `->im` (or the undocumented `->i` +
`object-contract` combo) basically useless.
Once/if that is added, then this commit would enable `->im`. Until then,
it's mostly useful for future reference (hence will be reverted).
In the meantime, it's possible to use `->i` within class/object contracts
with an explicit `this` argument, so nothing critical is lost, just a tiny
shortcut.
Previously, on the example, the function was not anonymous, so no
`tempN' would appear on the error message.
The fixed example makes use of `flat-named-contract' on an anonymous
function, which resembles the snippet above it and demonstrates the
purpose of `flat-named-contract' better.
