MatchesRegex and MSVC (GTEST_USES_SIMPLE_RE) #102

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago
Hi,

What steps will reproduce the problem?
I try to use gmock MatchesRegex on windows with vc2005.
In Google test documentation is written that on windows you use your own
simplified regex(GTEST_USES_SIMPLE_RE=1).
I think it could be valuable to use it in MatchesRegex.
I try to compile something like this:

TCHAR result[] =_T("Line 855");
EXPECT_THAT(result, ::testing::MatchesRegex(_T("Line \\d+")));
But I can’t.

What is the expected output? What do you see instead?
I get following errors:
error C2039: 'MatchesRegex' : is not a member of 'testing'
error C3861: 'MatchesRegex': identifier not found
error C2248: 'testing::AssertionResult::AssertionResult' : cannot access
private member declared in class 'testing::AssertionResult'

Any advice is welcome.

What version of the product are you using? On what operating system?
winxp, msvc2005, gmock 1.4.0

This was already fixed in the trunk.  Will be part of release 1.5.0.

When do you expect official release on 1.5.0?
Has it been settled already?

In the next several weeks.  You can use the code from the SVN today if you 
can't wait.

I got version from svn and tried it.
I tried to compile following tests:
TEST(MSVC_MatchesRegex, ansi)
{
  char res[]="line 123";
  EXPECT_THAT(res, ::testing::MatchesRegex("line \\d+"));
}

TEST(MSVC_MatchesRegex, wide)
{
  wchar_t res[]=L"line 123";
  EXPECT_THAT(res, ::testing::MatchesRegex(L"line \\d+"));
}

TEST(MSVC_MatchesRegex, tchar)
{
  TCHAR res[]=L"line 123";
  EXPECT_THAT(res, ::testing::MatchesRegex(_T("line \\d+")));
}

I got errors for version with wide chars:
error C2665: 'testing::MatchesRegex' : none of the 2 overloads could convert 
all the
argument types
C2512: 'testing::AssertionResult' : no appropriate default constructor available

It seems that it doesn't work with wide chars wchar_t.
Is there any workaround or what am I doing wrong?

I also find out that I can use backslash in regex used in windows version regex.

TEST(MSVC_MatchesRegex, backslash)
{
    char res[]="\\Device\\HarddiskVolume1\\windows\\system32\\hal.dll";
    EXPECT_THAT(res,
::testing::MatchesRegex("\\Device\\HarddiskVolume\\d+\\windows\\system32\\hal.dl
l"));
}

Is it possible?
I can't find it here
http://code.google.com/p/googletest/wiki/GoogleTestAdvancedGuide#Regular_Express
ion_Syntax
If not what about to define new escape code for example \\\ for \\.

No, we don't support wide string.  You need to convert it to narrow string 
yourself.

Write \\\\ to match a single \.  This is standard in C++ regular expressions.

Do you plan to add support for wide string MatchesRegex?

No, we don't.  Unless someone contributes a patch.

Is this issue related just to Windows platform or all platforms (meaning that 
it is
design of Your internal regex implementation)?
