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}");
