XOLINT(1) BSD General Commands Manual XOLINT(1)NAMExolint — detect errors in programs using xo_emit(3)SYNOPSISxolint [-c] [-C <flags>] [-d] [-D] [-I] [-p] [-V] [-X] [files...]
DESCRIPTIONxolint is a tool for reporting common mistakes in format strings in
source code that invokes xo_emit(3). It allows these errors to be diag‐
nosed at build time, rather than waiting until runtime.
xolint takes one or more C files as arguments, and reports error, warn‐
ing, 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}");
