This is ment to be used for debugging false positive errors in Cppcheck.
Current implementation tries two alternatives. Without all headers or with all headers and prints out the option with
less code. In future versions this could try with individual headers or group of header files.
New help text emphasizes we are ignoring/excluding source files.
The header files (include via source files) are not touched.
Ticket: #2965 (CLI: need better description for -i option (applies only to source files))
Initially I added logic that checked if excluded path was a file
we would accept. This works for source files, but when file with
"unknown" extension was given it was determined as a directory
name and ending slash was added. E.g. -ifile.h would end up
having ignored path file.h/.
This commit adds per-platform checks if the path points to the
file and if the file also exists.
We don't want to keep these deprecated options for ever. So lets
print a clear warning for the users and give also specific release
number when they will be removed. Users have a plenty of time to
update their scripts and environments before removal.
Ticket: #2515 (Print warning for deprecated command line options)
Fixes#2656 (-i Give path to ignore does not ignore if start of the
path is different than checked path)
Simplify paths given as -i options. This makes it easier to match
the paths as simplifying removes redundant parts.
Ticket #2686 (regression/bug in path handling)
There are situations that paths given to command line can contain
quotation marks. In normal situations shell removes them. For
these cases they don't get removed add code to check paths from
quotation marks and remove them.
This expands the CLI exclude feature to also allow excluding
filenames (with paths). When filename with recognized extension
is given to -i option then matching filenames (with paths) are
ignored when checking.
Ticket #2538 (Allow excluding files from the checking)
Add support for giving list of ignored paths from CLI. This way
user can define paths one doesn't want to check (like generated
code). This first simple implementation only does exact matching,
no support for wildcards etc. And matching is always agains dir
names.
If the filtered dir name is part of the checked filename then the
file is ignored.
Ticket #1690 (Ability to exclude files and directories from checks)
The --exitcode-suppressions option was inconsistent with other
long options by taking the filename as separate argument. Now
it expects format --exitcode-suppressions=filename.txt like
other long options.
Ticket: #1837 (--suppresions file.txt inconsistent)
