| /* |
| This test program is typically run indirectly, by the "wuffs test" or "wuffs |
| bench" commands. These commands take an optional "-mimic" flag to check that |
| Wuffs' output mimics (i.e. exactly matches) other libraries' output, such as |
| giflib for GIF, libpng for PNG, etc. |
| |
| To manually run this test: |
| |
| for CC in clang gcc; do |
| $CC -std=c99 -Wall -Werror cbor.c && ./a.out |
| rm -f a.out |
| done |
| |
| Each edition should print "PASS", amongst other information, and exit(0). |
| |
| Add the "wuffs mimic cflags" (everything after the colon below) to the C |
| compiler flags (after the .c file) to run the mimic tests. |
| |
| To manually run the benchmarks, replace "-Wall -Werror" with "-O3" and replace |
| the first "./a.out" with "./a.out -bench". Combine these changes with the |
| "wuffs mimic cflags" to run the mimic benchmarks. |
| */ |

| // Wuffs ships as a "single file C library" or "header file library" as per |
| // https://github.com/nothings/stb/blob/master/docs/stb_howto.txt |
| // |
| // To use that single file as a "foo.c"-like implementation, instead of a |
| // "foo.h"-like header, #define WUFFS_IMPLEMENTATION before #include'ing or |
| // compiling it. |
| #define WUFFS_IMPLEMENTATION |
| |
| // Defining the WUFFS_CONFIG__MODULE* macros are optional, but it lets users of |
| // release/c/etc.c choose which parts of Wuffs to build. That file contains the |
| // entire Wuffs standard library, implementing a variety of codecs and file |
| // formats. Without this macro definition, an optimizing compiler or linker may |
| // very well discard Wuffs code for unused codecs, but listing the Wuffs |
| // modules we use makes that process explicit. Preprocessing means that such |
| // code simply isn't compiled. |

| #define WUFFS_CONFIG__MODULE__BASE |
| #define WUFFS_CONFIG__MODULE__CBOR |

| // If building this program in an environment that doesn't easily accommodate |
| // relative includes, you can use the script/inline-c-relative-includes.go |
