Including files into executable

[Ad]

Hello,

I've written a simple program that sends a postscript snippet file to a
printer via LPT1. I want to include the file within the executable however.
How would I go about this?

Write a simple 'code generator', i.e.
write a short program that reads this file and writes
a source code file which defines an array or container
containing the text of the postscript file.
Use an #include directive at an appropriate place
in your orignal program to insert the generated
source code.

Roughly:

ifstream in("whatever.ps ");
ofstream out("ps.cpp");

out << "const char *ps[] = {\n"

while(getline(i n, line))
{
out << '"' << line << '"' << ',';
}

out << "\n};\n";


// yoursimpleprogr am.cpp
#include "ps.txt";
/* etc */
int main()
{
for(size_t i = 0 i < sizeof ps / sizeof *ps; ++i)
print_routine(p s[i]);

/* etc */
}

Include it as a resource.

Aggregate initialization cannot end with a comma.

That should be "ps.cpp".

Well, it's *kinda* roughly :)

Actually, it can.

It should be whatever OP wants. ".cpp" or
any other 'file name extension', or lack of
one, has no significance to the language.

I'm not familiar with the PS format so the point may be moot, but won't
this mess up if there is an embedded double-quote in the line?

Of course, you did say this was "rough" :)

Yes it would. But I'd rather leave dealing with such
details to the OP.
