-- | 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 (), in which case the result is
-- printed to stdout.
--
-- 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.
