* add @noInlineCall - see #640
This fixes a crash in --release-safe and --release-fast modes
where the optimizer inlines everything into _start and
clobbers the command line argument data.
If we were able to verify that the user's code never reads
command line args, we could leave off this "no inline"
attribute.
* add i29 and u29 primitive types. u29 is the type of alignment,
so it makes sense to be a primitive.
probably in the future we'll make any `i` or `u` followed by
digits into a primitive.
* add `aligned` functions to Allocator interface
* add `os.argsAlloc` and `os.argsFree` so that you can get
a `[]const []u8`, do whatever arg parsing you want, and then free
it. For now this uses the other API under the hood, but it could
be reimplemented to do a single allocation.
* add tests to make sure command line argument parsing works.
* @enumTagName renamed to @tagName and it works on enums and
union-enums
* Remove the EnumTag type. Now there is only enum and union,
and the tag type of a union is always an enum.
* unions support specifying the tag enum type, and they support
inferring an enum tag type.
* Enums no longer support field types but they do support
setting the tag values. Likewise union-enums when inferring
an enum tag type support setting the tag values.
* It is now an error for enums and unions to have 0 fields.
* switch statements support union-enums
closes#618
* rename decode to decodeExactUnsafe.
* add decodeExact, which checks for invalid chars and padding.
* add decodeWithIgnore, which also allows ignoring chars.
* alphabets are supplied to the decoders with their
char-to-index mapping already built, which enables it to be
done at comptime.
* all decode/encode apis except decodeWithIgnore require dest
to be the exactly correct length. This is calculated by a
calc function corresponding to each api. These apis no longer
return the dest parameter.
* for decodeWithIgnore, an exact size cannot be known a priori.
Instead, a calc function gives an upperbound, and a runtime
error is returned in case of overflow. decodeWithIgnore
returns the number of bytes written to dest.
closes#611
* fix fstat wrong on darwin
* move std.debug.global_allocator to std.debug.global_allocator_state and make it private
* add std.debug.global_allocator as a pointer (to upgrade your zig code remove
the '&')
I started working on #465 and made some corresponding std.io
API changes.
New structs:
* std.io.FileInStream
* std.io.FileOutStream
* std.io.BufferedOutStream
* std.io.BufferedInStream
Removed:
* std.io.File.in_stream
* std.io.File.out_stream
Now instead of &file.out_stream or &file.in_stream to get access to
the stream API for a file, you get it like this:
var file_in_stream = io.FileInStream.init(&file);
const in_stream = &file_in_stream.stream;
var file_out_stream = io.FileOutStream.init(&file);
const out_stream = &file_out_stream.stream;
This is evidence that we might not need any OOP features -
See #130.
* Merge io.InStream and io.OutStream into io.File
* Introduce io.OutStream and io.InStream interfaces
- io.File implements both of these
* Move mem.IncrementingAllocator to heap.IncrementingAllocator
Instead of:
```
%return std.io.stderr.printf("hello\n");
```
now do:
```
std.debug.warn("hello\n");
```
To print to stdout, see `io.getStdOut()`.
* Rename std.ArrayList.resizeDown to std.ArrayList.shrink.
