Then you can -run the program. - - gmock_gen.py header-file.h [ClassName]... - -If no ClassNames are specified, all classes in the file are emitted. - -To change the indentation from the default of 2, set INDENT in -the environment. For example to use an indent of 4 spaces: - -INDENT=4 gmock_gen.py header-file.h ClassName - -This version was made from SVN revision 281 in the cppclean repository. - -Known Limitations ------------------ -Not all code will be generated properly. For example, when mocking templated -classes, the template information is lost. You will need to add the template -information manually. - -Not all permutations of using multiple pointers/references will be rendered -properly. These will also have to be fixed manually. diff --git a/googlemock/scripts/generator/README.cppclean b/googlemock/scripts/generator/README.cppclean deleted file mode 100644 index 65431b61..00000000 --- a/googlemock/scripts/generator/README.cppclean +++ /dev/null @@ -1,115 +0,0 @@ -Goal: ------ - CppClean attempts to find problems in C++ source that slow development - in large code bases, for example various forms of unused code. - Unused code can be unused functions, methods, data members, types, etc - to unnecessary #include directives. Unnecessary #includes can cause - considerable extra compiles increasing the edit-compile-run cycle. - - The project home page is: http://code.google.com/p/cppclean/ - - -Features: ---------- - * Find and print C++ language constructs: classes, methods, functions, etc. - * Find classes with virtual methods, no virtual destructor, and no bases - * Find global/static data that are potential problems when using threads - * Unnecessary forward class declarations - * Unnecessary function declarations - * Undeclared function definitions - * (planned) Find unnecessary header files #included - - No direct reference to anything in the header - - Header is unnecessary if classes were forward declared instead - * (planned) Source files that reference headers not directly #included, - ie, files that rely on a transitive #include from another header - * (planned) Unused members (private, protected, & public) methods and data - * (planned) Store AST in a SQL database so relationships can be queried - -AST is Abstract Syntax Tree, a representation of parsed source code. -http://en.wikipedia.org/wiki/Abstract_syntax_tree - - -System Requirements: --------------------- - * Python 2.4 or later (2.3 probably works too) - * Works on Windows (untested), Mac OS X, and Unix - - -How to Run: ------------ - For all examples, it is assumed that cppclean resides in a directory called - /cppclean. - - To print warnings for classes with virtual methods, no virtual destructor and - no base classes: - - /cppclean/run.sh nonvirtual_dtors.py file1.h file2.h file3.cc ... - - To print all the functions defined in header file(s): - - /cppclean/run.sh functions.py file1.h file2.h ... - - All the commands take multiple files on the command line. Other programs - include: find_warnings, headers, methods, and types. Some other programs - are available, but used primarily for debugging. - - run.sh is a simple wrapper that sets PYTHONPATH to /cppclean and then - runs the program in /cppclean/cpp/PROGRAM.py. There is currently - no equivalent for Windows. Contributions for a run.bat file - would be greatly appreciated. - - -How to Configure: ------------------ - You can add a siteheaders.py file in /cppclean/cpp to configure where - to look for other headers (typically -I options passed to a compiler). - Currently two values are supported: _TRANSITIVE and GetIncludeDirs. - _TRANSITIVE should be set to a boolean value (True or False) indicating - whether to transitively process all header files. The default is False. - - GetIncludeDirs is a function that takes a single argument and returns - a sequence of directories to include. This can be a generator or - return a static list. - - def GetIncludeDirs(filename): - return ['/some/path/with/other/headers'] - - # Here is a more complicated example. - def GetIncludeDirs(filename): - yield '/path1' - yield os.path.join('/path2', os.path.dirname(filename)) - yield '/path3' - - -How to Test: ------------- - For all examples, it is assumed that cppclean resides in a directory called - /cppclean. The tests require - - cd /cppclean - make test - # To generate expected results after a change: - make expected - - -Current Status: ---------------- - The parser works pretty well for header files, parsing about 99% of Google's - header files. Anything which inspects structure of C++ source files should - work reasonably well. Function bodies are not transformed to an AST, - but left as tokens. Much work is still needed on finding unused header files - and storing an AST in a database. - - -Non-goals: ----------- - * Parsing all valid C++ source - * Handling invalid C++ source gracefully - * Compiling to machine code (or anything beyond an AST) - - -Contact: --------- - If you used cppclean, I would love to hear about your experiences - cppclean@googlegroups.com. Even if you don't use cppclean, I'd like to - hear from you. :-) (You can contact me directly at: nnorwitz@gmail.com) diff --git a/googlemock/scripts/generator/cpp/__init__.py b/googlemock/scripts/generator/cpp/__init__.py deleted file mode 100755 index e69de29b..00000000 --- a/googlemock/scripts/generator/cpp/__init__.py +++ /dev/null diff --git a/googlemock/scripts/generator/cpp/ast.py b/googlemock/scripts/generator/cpp/ast.py deleted file mode 100755 index 0e770163..00000000 --- a/googlemock/scripts/generator/cpp/ast.py +++ /dev/null @@ -1,1773 +0,0 @@ -#!/usr/bin/env python -# -# Copyright 2007 Neal Norwitz -# Portions Copyright 2007 Google Inc. -# -# Licensed under the Apache License, Version 2.0 (the "License"); -# you may not use this file except in compliance with the License. -# You may obtain a copy of the License at -# -# http://www.apache.org/licenses/LICENSE-2.0 -# -# Unless required by applicable law or agreed to in writing, software -# distributed under the License is distributed on an "AS IS" BASIS, -# WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. -# See the License for the specific language governing permissions and -# limitations under the License. - -"""Generate an Abstract Syntax Tree (AST) for C++.""" - -# FIXME: -# * Tokens should never be exported, need to convert to Nodes -# (return types, parameters, etc.) -# * Handle static class data for templatized classes -# * Handle casts (both C++ and C-style) -# * Handle conditions and loops (if/else, switch, for, while/do) -# -# TODO much, much later: -# * Handle #define -# * exceptions - - -try: - # Python 3.x - import builtins -except ImportError: - # Python 2.x - import __builtin__ as builtins - -import collections -import sys -import traceback - -from cpp import keywords -from cpp import tokenize -from cpp import utils - - -if not hasattr(builtins, 'reversed'): - # Support Python 2.3 and earlier. - def reversed(seq): - for i in range(len(seq)-1, -1, -1): - yield seq[i] - -if not hasattr(builtins, 'next'): - # Support Python 2.5 and earlier. - def next(obj): - return obj.next() - - -VISIBILITY_PUBLIC, VISIBILITY_PROTECTED, VISIBILITY_PRIVATE = range(3) - -FUNCTION_NONE = 0x00 -FUNCTION_CONST = 0x01 -FUNCTION_VIRTUAL = 0x02 -FUNCTION_PURE_VIRTUAL = 0x04 -FUNCTION_CTOR = 0x08 -FUNCTION_DTOR = 0x10 -FUNCTION_ATTRIBUTE = 0x20 -FUNCTION_UNKNOWN_ANNOTATION = 0x40 -FUNCTION_THROW = 0x80 -FUNCTION_OVERRIDE = 0x100 - -""" -These are currently unused.
