Bin to C

[Applewood]

Hi.

Anyone got a small widget to take a given file and save it back out as a const static array of numbers suitable for inclusion into source code ?

I need to embed a few things in a library and I figure this is the best way of doing it.

Yes, I know I could write something in about an hour to do it, but I'm sure someones beat me to it :)

Thanks....

This Lua program seems to work:


io.output ("out.c")

table.foreach ({a="a.dat", b="b.dat"},
function (var, file)
local inp = assert(io.open(file, "rb"))
local data = inp:read("*all")
data = string.gsub(data, ".",
function (ch) return string.byte (ch) .. "," end)
data = string.sub (data, 1, string.len (data) - 1)
data = string.gsub (data, "("..string.rep (",[^,]*", 8)..")",
function (s) return s .. "\n" end)
io.write(string.format ("const unsigned char %s[] = {\n%s}\n\n", var, data))
end)

io.close ()

To use, just add lua.exe in the same directory as the files, copy the script above in a "script.lua" file and call "lua.exe script.lua". Change the first line to generate output in the c file you like and decide what files to include by adding entries in the table on the second code line in the format varname="filename.ext"

It should be easy to set MSVC to automatically call the script during compile time.

Thanks man, but I'd prefer not to depend on Lua. In my development environment, Lua being installled isn't a given and I'd like to keep it easy to call (from a command line or recompileable c source).

Sorry, but thanks anwyays..

I half expected that, even though it's just getting the lua.exe file for Windows platforms. Just testing the "scripting language productivity" theory.

lol :)

I went for maximum productivity and found a link to a compiled C program on the net. Job done !

Thanks for the links above, Wayward. I realised I was being lazy and googled meself right after posting and found loads of em before you even read this.

Sorry to be bone idle guys :p
