XOLINT(1)              DragonFly General Commands Manual             XOLINT(1)


NAME

     xolint - detect errors in programs using xo_emit(3)


SYNOPSIS

     xolint [-c] [-C <flags>] [-d] [-D] [-I] [-p] [-V] [-X] [files...]


DESCRIPTION

     xolint is a tool for reporting common mistakes in format strings in
     source code that invokes xo_emit(3).  It allows these errors to be
     diagnosed at build time, rather than waiting until runtime.

     xolint takes one or more C files as arguments, and reports error,
     warning, or informational messages as needed.

     -c         Invoke 'cpp' against the input file

     -C <flags>
                Flags that are passed to 'cpp'

     -d         Enable debug output

     -D         Generate documentation for all xolint messages

     -I         Generate a table of xo_info_t structures.

     -p         Print the offending lines after the error message is displayed

     -V         Do not report errors, but instead print a complete list of all
                field names, sorted alphabetically.  The output can help spot
                inconsistencies and spelling errors.

     -X         Extract samples from xolint, suitable for internal testing.

     The output message contains the source filename and line number, the
     class of the message, the message, and, if -p is given, the line that
     contains the error:

               % xolint -t xolint.c
               xolint.c: 16: error: anchor format should be "%d"
               16         xo_emit("{[:/%s}");
