Functions ¶
func ExampleDumpConfig ¶
func ExampleDumpConfig(upper bool, bytesPerLine int) *hex.DumpConfig
ExampleDumpConfig returns an example hex.DumpConfig, with a prefix function generated by PrefixBytesNo and a suffix function generated by SuffixQuotedPretty.
upper indicates to use uppercase in the hexadecimal representation. bytesPerLine is the number of bytes to show in one line. If bytesPerLine is non-positive, it will use 16 instead.
func PrefixBytesNo ¶
PrefixBytesNo creates a function that generates a prefix to show the hexadecimal representation of the offset of the beginning of current line, in bytes.
If cfg != nil, cfg.BlockLen > 0, and cfg.BlocksPerLine > 0, it returns a prefix function used in DumpConfig that generates a prefix representing the byte offset of the beginning of current line, in hexadecimal representation, at least "digits" digits (padding with leading zeros if not enough). If digits is non-positive, it will use 8 instead. upper indicates to use uppercase in the hexadecimal representation. initCount specifies the byte offset of the first line.
Otherwise (cfg == nil, cfg.BlockLen <= 0, or cfg.BlocksPerLine <= 0), it returns nil.
func SuffixQuotedPretty ¶
func SuffixQuotedPretty(cfg *hex.DumpConfig) func(line []byte) []byte
SuffixQuotedPretty creates a function that generates a suffix consisting of " | " and the argument line represented in double-quoted Go string literal.
If cfg != nil, cfg.BlockLen > 0, and cfg.BlocksPerLine > 0, it returns a suffix function used in DumpConfig that generates a suffix consisting of " | " and the argument line represented in double-quoted Go string literal. If the length of line is less than cfg.BlockLen * cfg.BlocksPerLine, it pads spaces before " | ".
Otherwise (cfg == nil, cfg.BlockLen <= 0, or cfg.BlocksPerLine <= 0), it returns nil.
