"""pump v0.2.0 - Pretty Useful for Meta Programming.
A tool for preprocessor meta programming. Useful for generating
repetitive boilerplate code. Especially useful for writing C++
classes, functions, macros, and templates that need to work with
various number of arguments.
USAGE:
pump.py SOURCE_FILE
EXAMPLES:
pump.py foo.cc.pump
Converts foo.cc.pump to foo.cc.
GRAMMAR:
CODE ::= ATOMIC_CODE*
ATOMIC_CODE ::= $var ID = EXPRESSION
| $var ID = [[ CODE ]]
| $range ID EXPRESSION..EXPRESSION
| $for ID SEPARATOR [[ CODE ]]
| $($)
| $ID
| $(EXPRESSION)
| $if EXPRESSION [[ CODE ]] ELSE_BRANCH
| [[ CODE ]]
| RAW_CODE
SEPARATOR ::= RAW_CODE | EMPTY
ELSE_BRANCH ::= $else [[ CODE ]]
| $elif EXPRESSION [[ CODE ]] ELSE_BRANCH
| EMPTY
EXPRESSION has Python syntax.

"""fuse_gtest_files.py v0.2.0
Fuses Google Test source code into a .h file and a .cc file.
SYNOPSIS
fuse_gtest_files.py [GTEST_ROOT_DIR] OUTPUT_DIR
Scans GTEST_ROOT_DIR for Google Test source code, and generates
two files: OUTPUT_DIR/gtest/gtest.h and OUTPUT_DIR/gtest/gtest-all.cc.
Then you can build your tests by adding OUTPUT_DIR to the include
search path and linking with OUTPUT_DIR/gtest/gtest-all.cc. These
two files contain everything you need to use Google Test. Hence
you can "install" Google Test by copying them to wherever you want.
GTEST_ROOT_DIR can be omitted and defaults to the parent
directory of the directory holding this script.
EXAMPLES
./fuse_gtest_files.py fused_gtest
./fuse_gtest_files.py path/to/unpacked/gtest fused_gtest
This tool is experimental. In particular, it assumes that there is no
conditional inclusion of Google Test headers. Please report any
problems to googletestframework@googlegroups.com. You can read
http://code.google.com/p/googletest/wiki/GoogleTestAdvancedGuide for
more information.

"""pump v0.2.0 - Pretty Useful for Meta Programming.
A tool for preprocessor meta programming. Useful for generating
repetitive boilerplate code. Especially useful for writing C++
classes, functions, macros, and templates that need to work with
various number of arguments.
USAGE:
pump.py SOURCE_FILE
EXAMPLES:
pump.py foo.cc.pump
Converts foo.cc.pump to foo.cc.
GRAMMAR:
CODE ::= ATOMIC_CODE*
ATOMIC_CODE ::= $var ID = EXPRESSION
| $var ID = [[ CODE ]]
| $range ID EXPRESSION..EXPRESSION
| $for ID SEPARATOR [[ CODE ]]
| $($)
| $ID
| $(EXPRESSION)
| $if EXPRESSION [[ CODE ]] ELSE_BRANCH
| [[ CODE ]]
| RAW_CODE
SEPARATOR ::= RAW_CODE | EMPTY
ELSE_BRANCH ::= $else [[ CODE ]]
| $elif EXPRESSION [[ CODE ]] ELSE_BRANCH
| EMPTY
EXPRESSION has Python syntax.

"""fuse_gtest_files.py v0.2.0
Fuses Google Test source code into a .h file and a .cc file.
SYNOPSIS
fuse_gtest_files.py [GTEST_ROOT_DIR] OUTPUT_DIR
Scans GTEST_ROOT_DIR for Google Test source code, and generates
two files: OUTPUT_DIR/gtest/gtest.h and OUTPUT_DIR/gtest/gtest-all.cc.
Then you can build your tests by adding OUTPUT_DIR to the include
search path and linking with OUTPUT_DIR/gtest/gtest-all.cc. These
two files contain everything you need to use Google Test. Hence
you can "install" Google Test by copying them to wherever you want.
GTEST_ROOT_DIR can be omitted and defaults to the parent
directory of the directory holding this script.
EXAMPLES
./fuse_gtest_files.py fused_gtest
./fuse_gtest_files.py path/to/unpacked/gtest fused_gtest
This tool is experimental. In particular, it assumes that there is no
conditional inclusion of Google Test headers. Please report any
problems to googletestframework@googlegroups.com. You can read
http://code.google.com/p/googletest/wiki/GoogleTestAdvancedGuide for
more information.

"""fuse_gmock_files.py v0.1.0
Fuses Google Mock and Google Test source code into two .h files and a .cc file.
SYNOPSIS
fuse_gmock_files.py [GMOCK_ROOT_DIR] OUTPUT_DIR
Scans GMOCK_ROOT_DIR for Google Mock and Google Test source
code, assuming Google Test is in the GMOCK_ROOT_DIR/gtest
sub-directory, and generates three files:
OUTPUT_DIR/gtest/gtest.h, OUTPUT_DIR/gmock/gmock.h, and
OUTPUT_DIR/gmock-gtest-all.cc. Then you can build your tests
by adding OUTPUT_DIR to the include search path and linking
with OUTPUT_DIR/gmock-gtest-all.cc. These three files contain
everything you need to use Google Mock. Hence you can
"install" Google Mock by copying them to wherever you want.
GMOCK_ROOT_DIR can be omitted and defaults to the parent
directory of the directory holding this script.
EXAMPLES
./fuse_gmock_files.py fused_gmock
./fuse_gmock_files.py path/to/unpacked/gmock fused_gmock
This tool is experimental. In particular, it assumes that there is no
conditional inclusion of Google Mock or Google Test headers. Please
report any problems to googlemock@googlegroups.com. You can read
http://code.google.com/p/googlemock/wiki/CookBook for more
information.

A user can specify which test(s) in a Google Test program to run via either
the GTEST_FILTER environment variable or the --gtest_filter flag.
This script tests such functionality by invoking
gtest_filter_unittest_ (a program written with Google Test) with different
environments and command line flags.
Note that test sharding may also influence which tests are filtered. Therefore,
we test that here also.

"""pump v0.2.0 - Pretty Useful for Meta Programming.
A tool for preprocessor meta programming. Useful for generating
repetitive boilerplate code. Especially useful for writing C++
classes, functions, macros, and templates that need to work with
various number of arguments.
USAGE:
pump.py SOURCE_FILE
EXAMPLES:
pump.py foo.cc.pump
Converts foo.cc.pump to foo.cc.
GRAMMAR:
CODE ::= ATOMIC_CODE*
ATOMIC_CODE ::= $var ID = EXPRESSION
| $var ID = [[ CODE ]]
| $range ID EXPRESSION..EXPRESSION
| $for ID SEPARATOR [[ CODE ]]
| $($)
| $ID
| $(EXPRESSION)
| $if EXPRESSION [[ CODE ]] ELSE_BRANCH
| [[ CODE ]]
| RAW_CODE
SEPARATOR ::= RAW_CODE | EMPTY
ELSE_BRANCH ::= $else [[ CODE ]]
| $elif EXPRESSION [[ CODE ]] ELSE_BRANCH
| EMPTY
EXPRESSION has Python syntax.

"""fuse_gtest_files.py v0.2.0
Fuses Google Test source code into a .h file and a .cc file.
SYNOPSIS
fuse_gtest_files.py [GTEST_ROOT_DIR] OUTPUT_DIR
Scans GTEST_ROOT_DIR for Google Test source code, and generates
two files: OUTPUT_DIR/gtest/gtest.h and OUTPUT_DIR/gtest/gtest-all.cc.
Then you can build your tests by adding OUTPUT_DIR to the include
search path and linking with OUTPUT_DIR/gtest/gtest-all.cc. These
two files contain everything you need to use Google Test. Hence
you can "install" Google Test by copying them to wherever you want.
GTEST_ROOT_DIR can be omitted and defaults to the parent
directory of the directory holding this script.
EXAMPLES
./fuse_gtest_files.py fused_gtest
./fuse_gtest_files.py path/to/unpacked/gtest fused_gtest
This tool is experimental. In particular, it assumes that there is no
conditional inclusion of Google Test headers. Please report any
problems to googletestframework@googlegroups.com. You can read
http://code.google.com/p/googletest/wiki/GoogleTestAdvancedGuide for
more information.

// learn how Google Test works by reading its unit tests, read
// gtest_unittest.cc instead.
//
// This is intended as a regression test for the Google Test predicate
// assertions. We compile it as part of the gtest_unittest target
// only to keep the implementation tidy and compact, as it is quite
// involved to set up the stage for testing Google Test using Google
// Test itself.
//
// Currently, gtest_unittest takes ~11 seconds to run in the testing
// daemon. In the future, if it grows too large and needs much more
// time to finish, we should consider separating this file into a
// stand-alone regression test.

"""fuse_gtest_files.py v0.2.0
Fuses Google Test source code into a .h file and a .cc file.
SYNOPSIS
fuse_gtest_files.py [GTEST_ROOT_DIR] OUTPUT_DIR
Scans GTEST_ROOT_DIR for Google Test source code, and generates
two files: OUTPUT_DIR/gtest/gtest.h and OUTPUT_DIR/gtest/gtest-all.cc.
Then you can build your tests by adding OUTPUT_DIR to the include
search path and linking with OUTPUT_DIR/gtest/gtest-all.cc. These
two files contain everything you need to use Google Test. Hence
you can "install" Google Test by copying them to wherever you want.
GTEST_ROOT_DIR can be omitted and defaults to the parent
directory of the directory holding this script.
EXAMPLES
./fuse_gtest_files.py fused_gtest
./fuse_gtest_files.py path/to/unpacked/gtest fused_gtest
This tool is experimental. In particular, it assumes that there is no
conditional inclusion of Google Test headers. Please report any
problems to googletestframework@googlegroups.com. You can read
http://code.google.com/p/googletest/wiki/GoogleTestAdvancedGuide for
more information.
