PathBytes = 1024 ) // ToASCII removes all non-ASCII runes from the string. func ToASCII(s string) string { result := make([]rune, 0, len(s)) for _, r := range s { if r <= 127 { result = append(result, r) } } return string(result) } // Clip trims leading/trailing whitespace and limits the string to maxLen bytes // without splitting a multi-byte UTF-8 rune. func Clip(s string, maxLen int) string { return clip.Bytes(s, maxLen) } // ClipPath limits a filesystem path to the PathBytes byte budget on a UTF-8 // rune boundary, so a multi-byte path cannot overflow the album_path, // photo_path, or folders.path columns or break the byte-exact comparisons // between them. func ClipPath(p string) string { return clip.Bytes(p, PathBytes) } // ClipType normalizes identifier-like strings by stripping non-ASCII runes and clipping to 32 characters. func ClipType(s string) string { return Clip(ToASCII(s), TypeBytes) } // ClipTypeLower lowercases the string before applying ClipType. func ClipTypeLower(s string) string { return ClipType(strings.ToLower(s)) }
