Go lang中的打印格式列表

Question

只想使用fmt软件包的功能知道打印格式列表。

例如：

％v用于打印该值。 ％T可以打印值的类型。

还有什么？

Answer 1

的格式 “动词” 名单可在documentation of the fmt package：

一般：

%v the value in a default format. 
    when printing structs, the plus flag (%+v) adds field names 
%#v a Go-syntax representation of the value 
%T a Go-syntax representation of the type of the value 
%% a literal percent sign; consumes no value 

布尔：

%t the word true or false 

整数：

%b base 2 
%c the character represented by the corresponding Unicode code point 
%d base 10 
%o base 8 
%q a single-quoted character literal safely escaped with Go syntax. 
%x base 16, with lower-case letters for a-f 
%X base 16, with upper-case letters for A-F 
%U Unicode format: U+1234; same as "U+%04X" 

浮点和复杂的成分：

%b decimalless scientific notation with exponent a power of two, 
    in the manner of strconv.FormatFloat with the 'b' format, 
    e.g. -123456p-78 
%e scientific notation, e.g. -1234.456e+78 
%E scientific notation, e.g. -1234.456E+78 
%f decimal point but no exponent, e.g. 123.456 
%g whichever of %e or %f produces more compact output 
%G whichever of %E or %f produces more compact output 

字符串和切片的字节：

%s the uninterpreted bytes of the string or slice 
%q a double-quoted string safely escaped with Go syntax 
%x base 16, lower-case, two characters per byte 
%X base 16, upper-case, two characters per byte 

指针：

%p base 16 notation, with leading 0x 

其他标志：

+ always print a sign for numeric values; 
    guarantee ASCII-only output for %q (%+q) 
- pad with spaces on the right rather than the left (left-justify the field) 
# alternate format: add leading 0 for octal (%#o), 0x for hex (%#x); 
    0X for hex (%#X); suppress 0x for %p (%#p); 
    print a raw (backquoted) string if possible for %q (%#q); 
    write e.g. U+0078 'x' if the character is printable for %U (%#U). 
' ' (space) leave a space for elided sign in numbers (% d); 
    put spaces between bytes printing strings or slices in hex (% x, % X) 
0 pad with leading zeros rather than spaces
