There are plenty of topics here about making compilers...

that basically depends on how you're creating a message box ... and of what else you wish to do with your "application".
Compiler:
- identifies the text as
Code: Select all
<command>
<function name="msgbox">
<argument type="const string">"test"</argument>
<argument type="const string">"test"</argument>
</function>
</command>
this is the result of
parsing your text input.
- have a translator that knows how a 'function call' should be implemented. For instance (using perl-like syntax pseudocode)
Code: Select all
sub translate_function {
$address=$name_to_address_map{$function.name};
foreach $arg (@function.arguments) {
&translate($arg);
push @code, "call $address";
push @code, "add esp, ". 4*($#arg+1);
}
sub translate_const_string_argument {
push @code, "section .data\ndb str$STRID $content\n"
."section .code\n"
push @code, "push $STRID";
$STRID++;
}
