Compiling Code Inside #if 0

apdu_example.c uid_reader.c 1 nfc-typ... uid_reader.c > main 1 #if 0 2 gcc -o uid_reader "$0" -lnfc 3 ./uid_reader 4 exit 0 5 #endif 6 7 #include <nfc/nfc.h> 8 #include <stdlib.h>

A dark-themed code editor shows a C file where shell commands are placed inside a disabled #if 0 block before NFC-related includes. The joke is that compilation and execution instructions are embedded in source code but can never run because the block is excluded by the preprocessor, poking fun at improvised or confused programming workflows.
