2023-09-27Remove `@fabs`, fabs and absCast/Int from std libantlilja
Replaces occurences of @fabs absCast and absInt with new @abs builtin. Also removes the std.math.fabs alias from math.zig.

2023-01-29std: restrict mem.span() and mem.len() to sentinel terminated pointersIsaac Freund
These functions are currently footgunny when working with pointers to arrays and slices. They just return the stated length of the array/slice without iterating and looking for the first sentinel, even if the array/slice is a sentinel terminated type. From looking at the quite small list of places in the standard library/compiler that this change breaks existing code, the new code looks to be more readable in all cases. The usage of std.mem.span/len was totally unneeded in most of the cases affected by this breaking change. We could remove these functions entirely in favor of other existing functions in std.mem such as std.mem.sliceTo(), but that would be a somewhat nasty breaking change as std.mem.span() is very widely used for converting sentinel terminated pointers to slices. It is however not at all widely used for anything else. Therefore I think it is better to break these few non-standard and potentially incorrect usages of these functions now and at some later time, if deemed worthwhile, finally remove these functions. If we wait for at least a full release cycle so that everyone adapts to this change first, updating for the removal could be a simple find and replace without needing to worry about the semantics.

2021-08-24remove redundant license headers from zig standard libraryAndrew Kelley
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.

2020-06-08support Writer instead of OutStreamJonathan Marler
Start implementing https://github.com/ziglang/zig/issues/4917 which is to rename instream/outstream to reader/writer. This first change allows code to use Writer/writer instead of OutStream/outStream, but still maintains the old outstream names with "Deprecated" comments.
2020-03-13fix all the TODOs from the pull requestAndrew Kelley
* `std.Buffer.print` is removed; use `buffer.outStream().print` * `std.fmt.count` returns a `u64` * `std.Fifo.print` is removed; use `fifo.outStream().print` * `std.fmt.bufPrint` error is renamed from `BufferTooSmall` to `NoSpaceLeft` to match `std.os.write`. * `std.io.FixedBufferStream.getWritten` returns mutable buffer if the buffer is mutable.

2020-03-10(breaking) rework stream abstractionsAndrew Kelley
The main goal here is to make the function pointers comptime, so that we don't have to do the crazy stuff with async function frames. Since InStream, OutStream, and SeekableStream are already generic across error sets, it's not really worse to make them generic across the vtable as well. See #764 for the open issue acknowledging that using generics for these abstractions is a design flaw. See #130 for the efforts to make these abstractions non-generic. This commit also changes the OutStream API so that `write` returns number of bytes written, and `writeAll` is the one that loops until the whole buffer is written.
