6943cefebf std.os.path.dirname: return null instead of empty slice
for when there is no directory component. Makes it harder
to write bugs.

breaking syntax change: orelse keyword instead of ?? (#1096)
use the `zig-fmt-optional-default` branch to have zig fmt
automatically do the changes.

e514454c0e Make zig fmt exit with error on any parse errors
This is required for proper detection in editor plugins. Other files may
have been formatted correctly, this only indicates that some failed.

fcbb7426fa use * for pointer type instead of &
See #770

To help automatically translate code, see the
zig-fmt-pointer-reform-2 branch.

This will convert all & into *. Due to the syntax
ambiguity (which is why we are making this change),
even address-of & will turn into *, so you'll have
to manually fix thes instances. You will be guaranteed
to get compile errors for them - expected 'type', found 'foo'

717ac85a5a zig fmt: add --color option to CLI help text 2018-05-30 18:37:12 -04:00

a05acaf9fd Add --color CLI option to zig fmt
It doesn't actually do terminal color yet because we need to add
cross platform terminal color abstractions. But it toggles between
the single line error reporting and the multiline error reporting.

See #1026

803f0a295b Revise self-hosted command line interface
Commands are now separated more precisely from one another. Arguments
are parsed mostly using a custom argument parser instead of manually.
This should be on parity feature-wise with the previous main.zig but
adds a few extra code-paths as well that were not yet implemented.

Subcommands are much more prominent and consistent. The first argument
is always a sub-command and then all following arguments refer to that
command. Different commands display there own usage messages and options
based on what they can do instead of a one-for-all usage message that
was only applicable for the build commands previously.

The `cc` command is added and is intended for driving a c compiler. See #490.
This is currently a wrapper over the system cc and assumes that it
exists, but it should suffice as a starting point.

stage 2 compiler sans code generation and BUILD_INFO support.

445b03384a introduce std.heap.ArenaAllocator and std.heap.DirectAllocator
* DirectAllocator does the underlying syscall for every allocation.
 * ArenaAllocator takes another allocator as an argument and
   allocates bytes up front, falling back to DirectAllocator with
   increasingly large allocation sizes, to avoid calling it too often.
   Then the entire arena can be freed at once.

The self hosted parser is updated to take advantage of ArenaAllocator
for the AST that it returns. This significantly reduces the complexity
of cleanup code.

docgen and build runner are updated to use the combination of
ArenaAllocator and DirectAllocator instead of IncrementingAllocator,
which is now deprecated in favor of FixedBufferAllocator combined
with DirectAllocator.

The C allocator calls aligned_alloc instead of malloc, in order to
respect the alignment parameter.

Added asserts in Allocator to ensure that implementors of the
interface return slices of the correct size.

Fixed a bug in Allocator when you call realloc to grow the allocation.

46aa416c48 std.os and std.io API update
* move std.io.File to std.os.File
 * add `zig fmt` to self hosted compiler
 * introduce std.io.BufferedAtomicFile API
 * introduce std.os.AtomicFile API
 * add `std.os.default_file_mode`
 * change FileMode on posix from being a usize to a u32
 * add std.os.File.mode to return mode of an open file
 * std.os.copyFile copies the mode from the source file instead of
   using the default file mode for the dest file
 * move `std.os.line_sep` to `std.cstr.line_sep`

a2bd9f8912 std lib: modify allocator idiom
Before we accepted a nullable allocator for some stuff like
opening files. Now we require an allocator.

Use the mem.FixedBufferAllocator pattern if a bound on the amount
to allocate is known.

This also establishes the pattern that usually an allocator is the
first argument to a function (possibly after "self").

fix docs for std.cstr.addNullByte

self hosted compiler:
 * only build docs when explicitly asked to
 * clean up main
 * stub out zig fmt

3671582c15 syntax: functions require return type. remove ->
The purpose of this is:

 * Only one way to do things
 * Changing a function with void return type to return a possible
   error becomes a 1 character change, subtly encouraging
   people to use errors.

See #632

Here are some imperfect sed commands for performing this update:

remove arrow:

```
sed -i 's/\(\bfn\b.*\)-> /\1/g' $(find . -name "*.zig")
```

add void:

```
sed -i 's/\(\bfn\b.*\))\s*{/\1) void {/g' $(find ../ -name "*.zig")
```

Some cleanup may be necessary, but this should do the bulk of the work.

6fece14cfb self-hosted: build against zig_llvm and embedded LLD
