file2c — convert file to c-source


file2c [-sx] [-n count] [prefix [suffix]]


The file2c utility reads a file from stdin and writes it to stdout, converting each byte to
its decimal or hexadecimal representation on the fly. The byte values are separated by a
comma. This also means that the last byte value is not followed by a comma. By default the
byte values are printed in decimal, but when the -x option is given, the values will be
printed in hexadecimal. When -s option is given, each line is printed with a leading tab
and each comma is followed by a space except for the last one on the line.

If more than 70 characters are printed on the same line, that line is ended and the output
continues on the next line. With the -n option this can be made to happen after the
specified number of byte values have been printed. The length of the line will not be
considered anymore. To have all the byte values printed on the same line, give the -n
option a negative number.

A prefix and suffix strings can be printed before and after the byte values (resp.) If a
suffix is to be printed, a prefix must also be specified. The first non-option word is the
prefix, which may optionally be followed by a word that is to be used as the suffix.

This program is typically used to embed binary files into C source files. The prefix is
used to define an array type and the suffix is used to end the C statement. The -n, -s and
-x options are useful when the binary data represents a bitmap and the output needs to
remain readable and/or editable. Fonts, for example, are a good example of this.


The command:

date | file2c 'const char date[] = {' ',0};'

will produce:

const char date[] = {
