4.3.9.1 Input Format Types

The format types consist of a single character from the following list. LUX does not support C types u (unsigned integer), c (character).

d

Decimal integer. %hd generates a word, %ld and %d generate longs, %jd generates a int64.

i

Integer, which may be decimal, octal (leading 0), or hexadecimal (leading 0x or 0X). %hi generates a word, %li and %i generate longs, and %ji generates a int64.

o

Octal integer. %ho generates a word, %lo and %o generate longs, and %jo generates a int64.

x

Hexadecimal integer. %hx generates a word, %lx and %x generate longs, and %jx generates an int64.

e, f, g

Floating-point numbers, consisting of an optional sign, a string of numbers containing an optional decimal point, and an optional exponent field containing an e or E and an optionally signed integer exponent. %e, %f, and %g generate floats, %le, %lf, and %lg generate doubles.

s

A string consisting of the next non-whitespace characters (up to the field width). The result may be shorter than the field width, if whitespace or the end of the string intervene. If no field width is specified, then the next non-whitespace word is returned.

S

A string consisting of the next non-newline characters (up to the field width).

[...]

Matches the longest non-empty string of input characters from the set between brackets. If you want to include ] in the set, then place it directly after the initial [. Use a minus sign to indicate a range of characters, e.g. 0-9 for 0 through 9. If you want to include a minus sign itself, then make it the last element before the closing ].

[^...]

Matches the longest non-empty string of input characters that are not in the set between brackets. If you want to include ] in the set, then place it directly after the initial [^. For the rest, similar to [...]

T

A number in sexagesimal notation (e.g., times in hours, minutes, and seconds, or angles in degrees, minutes, and seconds). The number consists of two or more numerical components separated by any amount of non-digits. Only the first numerical component may be signed. All but the last numerical component must be integers; the last one may be floating-point (with a decimal point and/or exponent). The first numerical component counts units and each next numerical component counts 1/60th as much as the previous one.

z

A number in complex notation, consisting of an optionally signed floating-point number followed by a signed floating-point number followed by an i or I. The first number indicates the real part, and the second number the complex part of the result.

%

Literal %. No assignment is made.
