std.fmt.Formatter -> std.fmt.Alt
std.fmt.format -> std.Io.Writer.print
|
|
|
|
This "get" is useless noise and was copied from FixedBufferWriter.
Since this API has not yet landed in a release, now is a good time
to make the breaking change to fix this.

This use case is handled by ArrayListUnmanaged via the "...Bounded"
method variants, and it's more optimal to share machine code, versus
generating multiple versions of each function for differing array
lengths.

added adapter to AnyWriter and GenericWriter to help bridge the gap
between old and new API
make std.testing.expectFmt work at compile-time
std.fmt no longer has a dependency on std.unicode. Formatted printing
was never properly unicode-aware. Now it no longer pretends to be.
Breakage/deprecations:
* std.fs.File.reader -> std.fs.File.deprecatedReader
* std.fs.File.writer -> std.fs.File.deprecatedWriter
* std.io.GenericReader -> std.io.Reader
* std.io.GenericWriter -> std.io.Writer
* std.io.AnyReader -> std.io.Reader
* std.io.AnyWriter -> std.io.Writer
* std.fmt.format -> std.fmt.deprecatedFormat
* std.fmt.fmtSliceEscapeLower -> std.ascii.hexEscape
* std.fmt.fmtSliceEscapeUpper -> std.ascii.hexEscape
* std.fmt.fmtSliceHexLower -> {x}
* std.fmt.fmtSliceHexUpper -> {X}
* std.fmt.fmtIntSizeDec -> {B}
* std.fmt.fmtIntSizeBin -> {Bi}
* std.fmt.fmtDuration -> {D}
* std.fmt.fmtDurationSigned -> {D}
* {} -> {f} when there is a format method
* format method signature
- anytype -> *std.io.Writer
- inferred error set -> error{WriteFailed}
- options -> (deleted)
* std.fmt.Formatted
- now takes context type explicitly
- no fmt string

preparing to rearrange std.io namespace into an interface
how to upgrade:
std.io.getStdIn() -> std.fs.File.stdin()
std.io.getStdOut() -> std.fs.File.stdout()
std.io.getStdErr() -> std.fs.File.stderr()

closes #20663
|
|
Also remove `@frameSize`, closing #3654.
While the other machinery might remain depending on #23446, it is
settled that there will not be `async`/ `await` keywords in the
language.
|
|
Rename `trimLeft` to `trimStart`, and `trimRight` to `trimEnd`.
`trimLeft` and `trimRight` functions remain as deprecated aliases for
these new names.

This commits adds the following distinct integer types to std.zig.Ast:
- OptionalTokenIndex
- TokenOffset
- OptionalTokenOffset
- Node.OptionalIndex
- Node.Offset
- Node.OptionalOffset
The `Node.Index` type has also been converted to a distinct type while
`TokenIndex` remains unchanged.
`Ast.Node.Data` has also been changed to a (untagged) union to provide
safety checks.

Autodoc: Improve documentation for common types declared as type functions
|
|
|
|
such as ArrayList, StaticStringMap, BoundedArray, and more
|
|
Also includes panics by virtue of the previous commit, checking one item off #19249.
|
|
Using the browser's `console.error`, etc. functions instead of `console.log` produces prettier output in the console. Additionally, `console.error` in particular includes a stack trace, which is useful for debugging where the error occurred.
Additionally, this commit leverages the enhanced logging to delete the separate `panic` function from the JS code and write it in Zig instead.
|
|
Additionally, this commit streamlines the way unparseable files are handled, by giving them the AST of an empty file. This avoids bugs in the rest of the Autodoc logic trying to work with invalid ASTs.

The compiler actually doesn't need any functional changes for this: Sema
does reification based on the tag indices of `std.builtin.Type` already!
So, no zig1.wasm update is necessary.
This change is necessary to disallow name clashes between fields and
decls on a type, which is a prerequisite of #9938.

* new .zig-cache subdirectory: 'v'
- stores coverage information with filename of hash of PCs that want
coverage. This hash is a hex encoding of the 64-bit coverage ID.
* build runner
* fixed bug in file system inputs when a compile step has an
overridden zig_lib_dir field set.
* set some std lib options optimized for the build runner
- no side channel mitigations
- no Transport Layer Security
- no crypto fork safety
* add a --port CLI arg for choosing the port the fuzzing web interface
listens on. it defaults to choosing a random open port.
* introduce a web server, and serve a basic single page application
- shares wasm code with autodocs
- assets are created live on request, for convenient development
experience. main.wasm is properly cached if nothing changes.
- sources.tar comes from file system inputs (introduced with the
`--watch` feature)
* receives coverage ID from test runner and sends it on a thread-safe
queue to the WebServer.
* test runner
- takes a zig cache directory argument now, for where to put coverage
information.
- sends coverage ID to parent process
* fuzzer
- puts its logs (in debug mode) in .zig-cache/tmp/libfuzzer.log
- computes coverage_id and makes it available with
`fuzzer_coverage_id` exported function.
- the memory-mapped coverage file is now namespaced by the coverage id
in hex encoding, in `.zig-cache/v`
* tokenizer
- add a fuzz test to check that several properties are upheld

Fixes #20754
|
|
The old heuristic of checking only for the number of fields has the
downside of classifying all opaque types, such as `std.c.FILE`, as
"namespaces" rather than "types".

Deprecated aliases that are now compile errors:
- `std.fs.MAX_PATH_BYTES` (renamed to `std.fs.max_path_bytes`)
- `std.mem.tokenize` (split into `tokenizeAny`, `tokenizeSequence`, `tokenizeScalar`)
- `std.mem.split` (split into `splitSequence`, `splitAny`, `splitScalar`)
- `std.mem.splitBackwards` (split into `splitBackwardsSequence`, `splitBackwardsAny`, `splitBackwardsScalar`)
- `std.unicode`
+ `utf16leToUtf8Alloc`, `utf16leToUtf8AllocZ`, `utf16leToUtf8`, `fmtUtf16le` (all renamed to have capitalized `Le`)
+ `utf8ToUtf16LeWithNull` (renamed to `utf8ToUtf16LeAllocZ`)
- `std.zig.CrossTarget` (moved to `std.Target.Query`)
Deprecated `lib/std/std.zig` decls were deleted instead of made a `@compileError` because the `refAllDecls` in the test block would trigger the `@compileError`. The deleted top-level `std` namespaces are:
- `std.rand` (renamed to `std.Random`)
- `std.TailQueue` (renamed to `std.DoublyLinkedList`)
- `std.ChildProcess` (renamed/moved to `std.process.Child`)
This is not exhaustive. Deprecated aliases that I didn't touch:
+ `std.io.*`
+ `std.Build.*`
+ `std.builtin.Mode`
+ `std.zig.c_translation.CIntLiteralRadix`
+ anything in `src/`

We've got a big one here! This commit reworks how we represent pointers
in the InternPool, and rewrites the logic for loading and storing from
them at comptime.
Firstly, the pointer representation. Previously, pointers were
represented in a highly structured manner: pointers to fields, array
elements, etc, were explicitly represented. This works well for simple
cases, but is quite difficult to handle in the cases of unusual
reinterpretations, pointer casts, offsets, etc. Therefore, pointers are
now represented in a more "flat" manner. For types without well-defined
layouts -- such as comptime-only types, automatic-layout aggregates, and
so on -- we still use this "hierarchical" structure. However, for types
with well-defined layouts, we use a byte offset associated with the
pointer. This allows the comptime pointer access logic to deal with
reinterpreted pointers far more gracefully, because the "base address"
of a pointer -- for instance a `field` -- is a single value which
pointer accesses cannot exceed since the parent has undefined layout.
This strategy is also more useful to most backends -- see the updated
logic in `codegen.zig` and `codegen/llvm.zig`. For backends which do
prefer a chain of field and elements accesses for lowering pointer
values, such as SPIR-V, there is a helpful function in `Value` which
creates a strategy to derive a pointer value using ideally only field
and element accesses. This is actually more correct than the previous
logic, since it correctly handles pointer casts which, after the dust
has settled, end up referring exactly to an aggregate field or array
element.
In terms of the pointer access code, it has been rewritten from the
ground up. The old logic had become rather a mess of special cases being
added whenever bugs were hit, and was still riddled with bugs. The new
logic was written to handle the "difficult" cases correctly, the most
notable of which is restructuring of a comptime-only array (for
instance, converting a `[3][2]comptime_int` to a `[2][3]comptime_int`.
Currently, the logic for loading and storing work somewhat differently,
but a future change will likely improve the loading logic to bring it
more in line with the store strategy. As far as I can tell, the rewrite
has fixed all bugs exposed by #19414.
As a part of this, the comptime bitcast logic has also been rewritten.
Previously, bitcasts simply worked by serializing the entire value into
an in-memory buffer, then deserializing it. This strategy has two key
weaknesses: pointers, and undefined values. Representations of these
values at comptime cannot be easily serialized/deserialized whilst
preserving data, which means many bitcasts would become runtime-known if
pointers were involved, or would turn `undefined` values into `0xAA`.
The new logic works by "flattening" the datastructure to be cast into a
sequence of bit-packed atomic values, and then "unflattening" it; using
serialization when necessary, but with special handling for `undefined`
values and for pointers which align in virtual memory. The resulting
code is definitely slower -- more on this later -- but it is correct.
The pointer access and bitcast logic required some helper functions and
types which are not generally useful elsewhere, so I opted to split them
into separate files `Sema/comptime_ptr_access.zig` and
`Sema/bitcast.zig`, with simple re-exports in `Sema.zig` for their small
public APIs.
Whilst working on this branch, I caught various unrelated bugs with
transitive Sema errors, and with the handling of `undefined` values.
These bugs have been fixed, and corresponding behavior test added.
In terms of performance, I do anticipate that this commit will regress
performance somewhat, because the new pointer access and bitcast logic
is necessarily more complex. I have not yet taken performance
measurements, but will do shortly, and post the results in this PR. If
the performance regression is severe, I will do work to to optimize the
new logic before merge.

Previously, indentation was not being handled correctly in some cases,
causing examples such as `std.json.WriteStream` to be rendered with
improper list nesting.
Additionally, some more test cases have been added to ensure
indentation (or lack of indentation) is handled correctly in some other
constructs.

Autodoc: hyperlink URLs in text
|
|
Closes #19293
|
|
This extension to the typical `<>` Markdown autolink syntax allows
HTTP(S) links to be recognized in normal text without being delimited by
`<>`. This is the most natural way to write links in text, so it makes
sense to support it and allow documentation comments to be written in a
more natural way.
|
|
Closes #19265
This commit implements support for Markdown autolinks delimited by angle
brackets. The precise syntax accepted is documented in the doc comment
of `markdown.zig`.
|
|
A preceding `comptime` keyword was being ignored if the first
destructure variable was an expression.

It is no longer need to call skip if file content is not consumed. It is
handled internally now. File types are now same as in os.File.
