2

I am using the --red-only switch with the verbosity set to 2 to compile a very simple Red program to its Red/System equivalent. The program is:

Red []

red-load: func [source  [file! url! string! binary!]] [
    load source
]

It produces a certain amount of output, which I redirected to a file. My goal was to add a Red/System header to this and build it.

After getting rid of some commentary lines, the next barrier is that this code had not expanded at least some macros, so I had to add a #include for runtime/macros.reds. But then I got this error in the expansion of one of those (macros TO_CTX):

*** Compilation Error: invalid target type casting: red-context! 
*** in file: %/home/hostilefork/Projects/red/embedme.reds 
*** in function: f_modulo
*** at line: 11 
*** near: (as red-context! ((as series! ctx15/value) + 1))

I've seen red-context! and some other red-*! datatypes used in the Red runtime code...when Red/System needs to talk about values it gets from Red. But they are not mentioned in the Red/System spec. Can they be used in ordinary Red/System code, or is there something "special" allowing them only internally?

Verbosity 2 is not the right setting if you want to have a complete Red/System output, the verbosity should be set to 3 (-v 3). I never tried to actually compile such output, so I am not sure that it will work anyway. The --red-only? option purpose is for debugging the Red/System output from the high-level Red compiler.

The red-*! definitions are macros over Red internal structures, they are not part of Red/System. They are defined in the Red runtime library.

  • Thanks, it worked with minor tweaks. In this case, just the content of **output:** with search and replace `~%` => `~percent`, `~//` => `~slashslash`, `~/` => `~slash`...then and add an `#include` up top for `red.reds`. – HostileFork says dont trust SE Nov 28 '14 at 15:23
