-- Hoogle documentation, generated by Haddock -- See Hoogle, http://www.haskell.org/hoogle/ -- | A Perl printf like formatter. -- -- A Perl printf like formatter. @package printf-mauke @version 0.4 module Text.Printf.Mauke -- | Format a variable number of arguments according to a format string, -- similar to (s)printf in Perl. The return value is either a -- String or IO a, in which case the result is -- printed to stdout. If you use the IO variant, don't use -- the result: Because it has to be of any type a, this library -- makes it undefined. -- -- The format string consists of ordinary characters (everything except -- '%'), which are passed through unchanged, and formatting -- directives, which have the following form: -- --

--   % flag* vector? width? precision? type
--

-- -- (* and ? mean 0 or more and 0 or 1 of the preceding -- item, respectively.) -- -- Flags: -- --

space prefix positive numbers with a space
+ prefix positive numbers with a plus sign -- (overrides space if both are present)
- left-justify within the field
0 pad with zeroes on the left, not spaces
# prefix binary numbers with -- 0b/0B, octal numbers with 0o/0O -- and hexadecimal numbers with 0x/0X

-- -- The vector flag v tells printf to format each -- character in the string argument according to the current directive, -- then joins the results with a separator that defaults to ".". -- When *v is used, the separator is taken from the argument -- list (use e.g. printf "%*v.2x" "" str if you want no -- separator). -- -- The width is either a decimal integer or *, in which -- case the width is taken from the argument list (this argument must be -- an integer). It specifies the minimum width for this field. Shorter -- values are padded on the left with spaces (but this can be changed by -- the 0 and - flags). If the width taken from -- the argument list is negative, it behaves as if the - flag -- was specified. -- -- The precision consists of a . followed by digits or a -- * (see the description of width above). The effects -- depend on the format type: -- --

for floating point formats, this specifies the number of digits -- after the decimal point
for string formats, this is the maximum number of characters to -- appear (longer strings are truncated)
for integer formats, this is the minimum number of digits to -- appear in the output; shorter values are zero-padded

-- -- Types: -- --

% A percent sign. No argument is consumed.
c A character. If the argument is an integer, it -- is converted with chr.
s A string.
d A decimal integer.
u An unsigned decimal integer.
b A binary integer.
B Like b, but using a 0B prefix -- with #.
o An octal integer.
O Like o, but using a 0O prefix -- with #.
x A hexadecimal integer.
X Like x, but using uppercase -- letters.
e A floating point number in scientific -- notation.
E Like e, but using an uppercase -- E.
f A floating point number in fixed decimal -- notation.
g A floating point number in %e or -- %f notation.
G Like g, but using an uppercase -- E.
_ A generic format; it behaves like %c, -- %s, %d or %g, depending on the argument -- type.
