1 This is automated checker to make sure a C++ file follows Google's C++ style 2 guide (https://google.github.io/styleguide/cppguide.html). As it 3 heavily relies on regular expressions, cpplint.py won't catch all violations of 4 the style guide and will very occasionally report a false positive. There is a 5 list of things we currently don't handle very well at the top of cpplint.py, 6 and we welcome patches to improve it. 7 8 The linting tool takes a list of files as input. For full usage instructions, 9 please see the output of: 10 11 ./cpplint.py --help 12 13 Unit tests are provided in cpplint_unittest.py. This file can safely be ignored 14 by end users who have downloaded this package and only want to run the lint 15 tool. 16 17 --- 18 19 cpplint.py and its corresponding unit tests are Copyright (C) 2009 Google Inc. 20 21 Redistribution and use in source and binary forms, with or without 22 modification, are permitted provided that the following conditions are 23 met: 24 25 * Redistributions of source code must retain the above copyright 26 notice, this list of conditions and the following disclaimer. 27 * Redistributions in binary form must reproduce the above 28 copyright notice, this list of conditions and the following disclaimer 29 in the documentation and/or other materials provided with the 30 distribution. 31 * Neither the name of Google Inc. nor the names of its 32 contributors may be used to endorse or promote products derived from 33 this software without specific prior written permission. 34 35 THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS 36 "AS IS" AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT 37 LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR 38 A PARTICULAR PURPOSE ARE DISCLAIMED.
