Quick-start with manual compilation

  • Generate Toggle files in include/ and src/ using files in yaml/.
$ ../generate.py
  • Compile (should warn about using default CHAR_ID).
  • Execute.
$ gcc -o main main.c src/toggle.c -I include/
... "CHAR_ID is not defined. Using default." ...

$ ./main
DEBUG: main: begin
+----------------+

TEST: main: changing display from 16x2 to 20x4

|                    |
+--------------------+
DEBUG: main: end
  • Compile defining CHAR_ID to select the characterization for tests.
  • Execute.
$ gcc -o main main.c src/toggle.c -I include/ -D CHAR_ID=CHAR_ID_TEST
$ ./main
