Package strcase and bytcase are case-insensitive and
Unicode aware implementations of the Go standard library's
strings and bytes
packages that are accurate, fast, and never allocate memory.
Simple Unicode case-folding is used for all comparisons. This matches the behavior
of strings.EqualFold and regexp.Regexp
(when the pattern is compiled with the case-insensitive flag (?i)) and is more
accurate (and significantly more efficient) than using strings.ToLower or
strings.ToUpper to normalize the needle /
haystack before searching.
Note: The bytcase package is analogous to the strcase package; whatever applies to strcase also applies to bytcase. For simplicity, the documentation primarily refers to strcase. Unless otherwise noted, all comments apply to both packages.
- Drop-in replacement for the
stringsandbytespackages that provides Unicode aware case-insensitive matching. - Simple Unicode case-folding is used for all comparisons - making it more accurate than using strings.ToLower or strings.ToUpper for case-insensitivity.
- Any string matched by strcase or bytcase will also match with strings.EqualFold or bytes.EqualFold
- Fast and optimized for amd64 and arm64. For non-pathological inputs strcase is only 25-50% slower than the strings package.
- On average strcase/bytcase are 25x faster than using than using a case-insensitive regexp.Regexp (see the below benchmarks section).
strcase is available using the standard go get command.
Install by running:
# strcase
go get github.com/charlievieth/strcase
# bytcase
go get github.com/charlievieth/strcase/bytcase- Fast: strcase is optimized for
amd64andarm64and strives to be no worse than 2x slower than the strings package and is often only 30-50% slower.- The
IndexByte,IndexNonASCIIandCountfunctions are implemented in assembly and use SSE/AVX2 onamd64and NEON onarm64. - Instead of using the unicode package for case conversions strcase uses its own multiplicative hash tables that are roughly 10x faster (at the cost of package size).
- The
- Accurate: Unicode simple folding is used to determine equality.
- Any matched text would also match with
strings.EqualFold.
- Any matched text would also match with
- Zero allocation: none of the strcase functions allocate memory.
- Thoroughly tested and fuzzed.
strcase provides two functons for checking if a string contains non-ASCII characters that are highly optimized for amd64/arm64:
- strcase.IndexNonASCII: IndexNonASCII returns the index of first non-ASCII rune in s, or -1 if s consists only of ASCII characters.
- strcase.ContainsNonASCII: ContainsNonASCII returns true if s contains any non-ASCII characters.
All invalid UTF-8 sequences are considered equal. This is because Go converts
invalid UTF-8 sequences to the Unicode replacement character 0xFFFD
(unicode.ReplacementChar /
utf8.RuneError).
This occurs both when ranging over
a string or using the utf8 package's Decode*
functions.
strcase.Compare("\xff", string(utf8.RuneError)) // returns 0
strcase.Index("a\xff", string(utf8.RuneError)) // returns 1Thus it is the callers responsibility to ensure strcase functions are called with valid UTF-8 strings and not arbitrary binary data.
strcase aims to be seriously fast and can beat or match the performance of the strings package in some benchmarks (EqualFold and IndexRune). Overall, strcase tends to be only 30-50% slower than the strings package for non-pathological inputs.
- Instead of using the standard library's Unicode package, which uses a binary search for its lookup tables, strcase uses multiplicative hashing for its lookup tables. This is 10x faster at the cost of larger tables.
- Searching for runes (IndexRune) is a big determinant of the strcase packages
performance. Instead of searching for runes by their first byte (like the
strings package) strcase searches for the second byte, which is more unique,
then looks backwards/forwards to complete the match.
- NB: CL 539116 added this logic to Go's strings/bytes packages and is available starting with Go 1.23.
- Package strcase is optimized for amd64 and arm64 and includes assembly
implementations of
IndexByte,CountByteandIndexNonASCIIthat leverage the same SIMD technologies used in the standard library (SSE, AVX2, NEON). - On armv7l (Raspberry Pi), which we do not optimize for, the average performance penalty is only ~30%.
- All invalid Unicode points and invalid multibyte UTF-8 sequences are
considered equal.
This is because the utf8 package converts
invalid runes and multibyte UTF-8 sequences to
utf8.RuneError.- This matches the behavior of strings.EqualFold.
İ(LATIN CAPITAL LETTER I WITH DOT ABOVE) andı: (LATIN SMALL LETTER DOTLESS I) doe not fold to ASCII[iI](U+0069 / U+0049)- This matches the behavior of strings.EqualFold
- See unicode.org/UCD/CaseFolding.txt for an explanation, basically this folding is normally ignored for non-Turkic languages
- Kelvin
K(U+212A) matches ASCIIKandk - Latin small letter long S
ſmatches ASCIISands
