Charlie Vieth
v0.0.4
This release adds the bytecase package, consolidates tests, fixes the
handling of invalid UTF-8 encodings, and fixes CPU feature detection
on AMD64.
With this release the strcase and bytcase packages are functionally complete
and sufficiently tested to be considered accurate, if not authoritative.
The only planned changes from here will by to improve the performance of the
strcase and bytcase packages and to add functions for ASCII only matching.

internal/bytealg: fix amd64 cpu feature detection
This changes bytealg to actually use the golang.org/x/sys/cpu package to
detect CPU features, which resolves an issue where POPCNT was not
detected when GOAMD=v1.

strcase/bytcase: don't fold LATIN SMALL LETTER DOTLESS I
Change code to not fold 'ı' (LATIN SMALL LETTER DOTLESS I). The issue
here is that 'ı' and 'İ' have an upper/lower case, but no folds and we
were incorrectly using the upper case form of 'ı' in comparisons.
TODO: change the generation logic to exclude 'ı' and 'İ' from the
upper/lower case table.

internal/benchtest/Makefile: fix variable passing in release target
Previously, for the "release" target we shelled out to make so that we
could tee the output to a file, which makes passing any variables a pain
(since we need to pass all of them when invoking the make child
process). This commit changes the Makefile so that the existing targets
can conditionally tee to a file - thus we don't have to shell out.

Date: Fri Aug 9 11:30:13 2024 -0500
strcase: inline indexUnicode into Index
commit 5d0f2d0
Author: Charlie Vieth charlie.vieth@gmail.com
Date: Fri Aug 9 11:28:16 2024 -0500
strcase: cleanup and test nonLetterASCII
commit 441d39c
Author: Charlie Vieth charlie.vieth@gmail.com
Date: Thu Aug 8 15:49:09 2024 -0600
strcase: remove ASCII check from indexByte
Remove the ASCII check because it was slower and was generally a bad
idead in the first place since indexRuneCase is faster and the bytes
being sought cannot occur in an ASCII only string.
TLDR: We we're potentially scanning the haystack twice for no benefit.
commit b0e1f9a
Author: Charlie Vieth charlie.vieth@gmail.com
Date: Thu Aug 8 15:22:22 2024 -0600
strcase: improve indexRuneCase performance by ~45%
This changes indexRuneCase to search for runes using the last byte of
their UTF-8 encoded form and to use bytealg.IndexString if IndexByte
produces too many false positives.
