| #!/usr/bin/env awk -f | |
| # Given a C-like header file, this AWK script will generate a sequence | |
| # of case statements for stringifying macro names. | |
| # | |
| # For example, if the input file looks like this: | |
| # | |
| # #define kIOReturnSuccess KERN_SUCCESS // OK | |
| # #define kIOReturnError iokit_common_err(0x2bc) // general error | |
| # #define kIOReturnNoMemory iokit_common_err(0x2bd) // can't allocate memory | |
| # | |
| # Then the output will look like this: | |
| # | |
| # case kIOReturnSuccess: | |
| # return "kIOReturnSuccess"; | |
| # case kIOReturnError: | |
| # return "kIOReturnError"; | |
| # case kIOReturnNoMemory: | |
| # return "kIOReturnNoMemory"; | |
| # | |
| # Any input lines that don't start with "#define" are ignored. | |
| /^ *#define [a-zA-Z0-9_]+/ { printf "case %s:\n return \"%s\";\n", $2, $2 } | |
