When os/stat is not available, we first
try to read one byte from the file before
saying it is good. If that fails, it is not
a file that we can read from so it counts as not found.
By holding on a reference to argv for a long time, we
may trigger a use after free bug if the stack is resized. In
janet c function, argv is only vvalid up until the next stack operation
on the fiber. We could say that this is the dynamic lifetime of
argv.
To fix this, we copy extra arguments into a tuple, which is properly
garbage collected.
Some peg grammars could not capture values based on their position in a
larger grammar. This is a design limitation inheritted from LPeg, but no
longer needed as the replace mode is superseded by the accumulator mode,
which is more general if slightly harder to use.
Allows getting more information about files. This
is really useful for writing software that needs to inspect
the file system (like a static site generator). We still need
a way to iterate directories though.
Rather than edit the Makefile or the janet.h header yourself, use
janetconf.h to configure builds. This has the benefit of making it
easier to configure janet in a persitent but easy way.
A lot of refactoring larger integer types. Fix a number
of casting errors, but mostly rename things. Also try to
limit use of template-like macros as they bloat the binary
if not used in moderation. We were able to reduce the size of
typed array code as well by using a single view types.
We moved the literals true and false into one tag
type, so we an extra tag for raw pointer types
(light userdata). These can be used from the C API via
janet_wrap_pointer and janet_unwrap_pointer.
If -p flag is not set, we should bail on all three kinds
of errors, not just runtime errors. This includes
parse and compile errors. Before, parse and compile errors
were not properly affected by the :exit parameter to require, which
in turn caused scripts to not bail on parse or compile errors.
