.. title:: clang-tidy - portability-restrict-system-includes

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.
