Yes, it does match. Which is why it's not moving into the else branch. But without a matching group it doesn't know what to put into $1, so it just prints an empty line.
Compare your code with this:
Code:
my $test = "SWER~~ERTGSDFGTHAS_RTAWGA_DFAS.x4-234253454.in";
if ($test = ~ m/(~{1,2}[A-Z].*[xX]4)/) {
print "$1\n";
}
else {
print "No match...\n";
}
I am using GnuWin32 sed and am having trouble with the regexp - i.e., they don't behave the same way as in UNIX (POSIX and and all that). I have a stream of data, e.g.:
11111'222?'22'33?'333'44444'55555'
I want to insert a \n after those apostrophes that are *not* preceded by a ?.

... // ... ( there is "//" somewhere on the line and on the end of the line there ISN'T "*/" )
I've tried something like : (in SED)
sed 's/\/\/'

wibble-test-genrunner
wibble-test-genrunner(1) General Commands Manual wibble-test-genrunner(1)NAME
wibble-test-genrunner - Code generator for wibble testsuites.
SYNOPSIS
wibble-test-genrunner header <file>
wibble-test-genrunner main <files>
DESCRIPTION
The program generates .cpp files that are then compiled and linked into a test program for running tests from .test.h files. Examples of
such .test.h files may be found among wibble headers, eg. /usr/include/wibble/regexp.test.h.
In the first form, the program processes a single header file (usually of the form foo.test.h) and produces a corresponding .cpp file to be
compiled. In the second form, it takes as <files> all the .test.h headers and produces a single main.cpp which contains the main() function
of the test program, which then runs all the tests in all the .test.h files. The generated source code is always written to standard output
and it is left up to the user to redirect it to a meaningful location.
The program currently has no options other than the two forms above. The program is intended to be run as part of build process of programs
or libraries using the wibble testing framework. For convenient use from CMake, there is a test.cmake script under /usr/share/wibble, that
takes care of producing all the .cpp files (both per-header and the main one), compiling them and linking them into a single binary which
executes the testsuite.
