This optimization is used in `mem.eql`, but was missing from `order`,
`orderZ`, and `ascii.orderIgnoreCase`.
|
|
std.fmt.Formatter -> std.fmt.Alt
std.fmt.format -> std.Io.Writer.print
|
|
and delete deprecated alias std.io
|
|
Basically everything that has a direct replacement or no uses left.
Notable omissions:
- std.ArrayHashMap: Too much fallout, needs a separate cleanup.
- std.debug.runtime_safety: Too much fallout.
- std.heap.GeneralPurposeAllocator: Lots of references to it remain, not
a simple find and replace as "debug allocator" is not equivalent to
"general purpose allocator".
- std.io.Reader: Is being reworked at the moment.
- std.unicode.utf8Decode(): No replacement, needs a new API first.
- Manifest backwards compat options: Removal would break test data used
by TestFetchBuilder.
- panic handler needs to be a namespace: Many tests still rely on it
being a function, needs a separate cleanup.

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

Now these show up as "example usage" in generated documentation.

On x86 interestingly I can see a reduction in codesize by 1 instruction with this.
While not necessarily faster, it might still reduce codesize a bit and this ordering is also more logical
because it follows ASCII table order. Rust's std uses this ordering too.
See https://zig.godbolt.org/z/PqodY8YqY for the difference.

This makes it so that we no longer use a LUT (Look-Up Table):
* The code is much simpler and easier to understand now.
* Using a LUT means we rely on a warm cache.
Relying on the cache like this results in inconsistent performance and in many cases codegen will be worse.
Also as @topolarity once pointed out, in some cases while it seems like the code may branch, it actually doesn't:
https://github.com/ziglang/zig/pull/11629#issuecomment-1213641429
* Other languages' standard libraries don't do this either.
JFF I wanted to see what other languages codegen compared to us now:
https://rust.godbolt.org/z/Te4ax9Edf, https://zig.godbolt.org/z/nTbYedWKv
So we are pretty much on par or better than other languages now.

It was supposed to be removed: https://github.com/ziglang/zig/commit/490654c332f2d8eaf7edffa35ea0523800df998d#r47643278

And improve some existing docs.

`isAlNum` and `isAlpha`:
1. I think these names are a bit cryptic.
2. `isAlpha` is a bit ambiguous: is it alpha*numeric* or alpha*betic*?
This is why I renamed `isAlpha` to `isAlphabetic`.
3. For consistency and because `isAlNum` looks weird, I renamed it to `isAlphanumeric`.
`isCntrl`:
1. It's cryptic and hard to find when you look for it.
2. We don't save a lot of space writing it this way.
3. It's closer to the name of the `control_code` struct.
`isSpace`:
1. The name is ambiguous and misleading.
`spaces`:
1. Ditto
`isXDigit`:
1. The name is extremely cryptic.
2. The function is very hard to find by its name.

I think `isBlank` and `isWhitespace` are quite confusable.
What `isBlank` does is so simple that you can just do the `c == ' ' or c == '\t'`
check yourself but in a lot of cases you don't even want that.
`std.ascii` can't really know what you think "blank" means.
That's why I think it's better to remove it.
And again, it seems ambiguous considering that we have `isWhitespace`.
Next, it also deprecates `isGraph`.
It's the same as `isPrint(c) and c != ' '`, which I find confusing.
When something is printable, you can say it also has a *graph*ical representation.
Removing `isGraph` solves this possible confusion.

0x1F (`control_code.us`) itself is also a control code.
|
|
It lowercases all constants and documents them.

We already have a LICENSE file that covers the Zig Standard Library. We
no longer need to remind everyone that the license is MIT in every single
file.
Previously this was introduced to clarify the situation for a fork of
Zig that made Zig's LICENSE file harder to find, and replaced it with
their own license that required annual payments to their company.
However that fork now appears to be dead. So there is no need to
reinforce the copyright notice in every single file.

For sorting ascii strings, case insensitively.
|
|
|
|
* startsWithIgnoreCase
* endsWithIgnoreCase
|
|
This may be combined with std.mem.trim to form a proper replacement for
the now deprecated std.fmt.trimWhitespace().
|
|
add SPDX license identifier
copyright ownership is zig contributors

constants.
|
|
The `matchCase` variants are simply duplicates of the `eql` and
`indexOf` functions found in std.mem.
|
|
* Add an upper case variant of `allocLowerString`
* Add case-sensitive variants of `eqlIgnoreCase`, `indexOfIgnoreCase`,
and `indexOfIgnoreCasePos`
* Add and update docstrings on functions

that's all this commit does. further commits will fix cli flags and
such.
