portability-restrict-system-includes
|
|
====================================
|
|
|
|
Checks to selectively allow or disallow a configurable list of system headers.
|
|
|
|
For example:
|
|
|
|
In order to **only** allow `zlib.h` from the system you would set the options
|
|
to `-*,zlib.h`.
|
|
|
|
.. code-block:: c++
|
|
|
|
#include <curses.h> // Bad: disallowed system header.
|
|
#include <openssl/ssl.h> // Bad: disallowed system header.
|
|
#include <zlib.h> // Good: allowed system header.
|
|
#include "src/myfile.h" // Good: non-system header always allowed.
|
|
|
|
In order to allow everything **except** `zlib.h` from the system you would set
|
|
the options to `*,-zlib.h`.
|
|
|
|
.. code-block:: c++
|
|
|
|
#include <curses.h> // Good: allowed system header.
|
|
#include <openssl/ssl.h> // Good: allowed system header.
|
|
#include <zlib.h> // Bad: disallowed system header.
|
|
#include "src/myfile.h" // Good: non-system header always allowed.
|
|
|
|
Since the options support globbing you can use wildcarding to allow groups of
|
|
headers.
|
|
|
|
`-*,openssl/*.h` will allow all openssl headers but disallow any others.
|
|
|
|
.. code-block:: c++
|
|
|
|
#include <curses.h> // Bad: disallowed system header.
|
|
#include <openssl/ssl.h> // Good: allowed system header.
|
|
#include <openssl/rsa.h> // Good: allowed system header.
|
|
#include <zlib.h> // Bad: disallowed system header.
|
|
#include "src/myfile.h" // Good: non-system header always allowed.
|
|
|
|
Options
|
|
-------
|
|
|
|
.. option:: Includes
|
|
|
|
A string containing a comma separated glob list of allowed include
|
|
filenames. Similar to the -checks glob list for running clang-tidy itself,
|
|
the two wildcard characters are `*` and `-`, to include and exclude globs,
|
|
respectively. The default is `*`, which allows all includes.
