csgrep: filter the list of defects by the specified regex-based predicates

NAME

csgrep - filter the list of defects by the specified regex-based predicates

SYNOPSIS

csgrep [options] [file1.err [...]], where options are:

DESCRIPTION

--checker arg
defect matches if its checker matches the given regex (each defect has assigned exactly one checker)
--path arg
defect matches if the path of its key event matches the given regex
--event arg
defect matches if its key event matches the given regex (each defect has exactly one key event, which determines its location in the code)
--error arg
defect matches if the message of its key event matches the given regex
--msg arg
defect matches if any of its messages matches the given regex
--annot arg
defect matches if its annotation matches the given regex
--src-annot arg
defect matches if an annotation in the _source_ file matches the given regex
-U [ --embed-context ] arg
embed a number of lines of context from the source file for the key event
--prune-events arg
event is preserved if its verbosity level is below the given number
-u [ --remove-duplicates ]
remove defects that are not unique by their key event
--strip-path-prefix arg
string prefix to strip from path (applied after all filters)
-i [ --ignore-case ]
ignore case when matching regular expressions
-v [ --invert-match ]
select defects that do not match the selected criteria
-n [ --invert-regex ]
invert regular expressions in all predicates
--color
use colorized console output (default if connected to a terminal)
--no-color
do not use colorized console output
-q [ --quiet ]
do not report any parsing errors
--mode arg (=grep)
grep, json, stat, grouped, files, filestat, or dig_key_events
--help
print the usage of csgrep
--version
print the version of csgrep

EXAMPLE - CHECKERS, EVENTS, MESSAGES

Error: FORWARD_NULL (CWE-476):
libhsm.c:1168: assign_zero: Assigning: key_handles = NULL.
libhsm.c:1210: var_deref_op: Dereferencing null pointer key_handles.

In the above example, FORWARD_NULL is the checker , assign_zero and var_deref_op are events , where var_deref_op is the key event and "Dereferencing null pointer key_handles." is the message associated with the key event.

DESCRIPTION OF AVAILABLE MODES

dig_key_events - for each defect, print only the checker and key event

evtstat - print overall checker/key_event statistics for the matched defects

files - print only names of error files that contain the matched defects

filestat - print statistics of matched defects per individual source files

grep - print matched defects using the same format as expected on the input

grouped - print matched defects, grouped by error files they originate from

json - print matched defects in a JSON format

stat - print overall statistics of the matched defects in given error files
