c# - Regex expression for string matching -

-

i need match string "*b*[xxx]". example "mb0[23]" or "db50.dbb152[128]". @ moment, it's complicated me.

please help.

if right example, format has contain capital b , brackets numbers in it. try use 1 of these:

this strings contain "b" , brackets after (with optional contents):

char c = convert.tochar(65535); string format = @"/(?:[\0-" + c + @"]+)?b(?:[\0-" + c + @"]+)?\[(?:[\0-" + c + @"]+)?\]/";

this strings contain "b" , brackets after numbers or nothing in it:

char c = convert.tochar(65535); string format = @"/(?:[\0-" + c + @"]+)?b(?:[\0-" + c + @"]+)?\[(?:\d+)?\]/";

this strings contain "b" , brackets after numbers in it:

char c = convert.tochar(65535); string format = @"/(?:[\0-" + c + @"]+)?b(?:[\0-" + c + @"]+)?\[(?:\d+)\]/";

this should match both examples provided. can check , learn format here: http://www.regexr.com/

python - jinja2: TemplateSyntaxError: expected token ',', got 'string' -

i new jinja2 , having issue using python regular expression (re). in following code bold lines have error string in them. {% block content %} <div class="container"> {% l in lines %} {% if re.search(r"error", l) %} {# <<< throws error #} <b> {{ l }} </b> {% else %} {{ l }} <hr> {% endif %} {% endfor %} </div> {% endblock %} the re.search above throws following error: jinja2.exceptions.templatesyntaxerror templatesyntaxerror: expected token ',', got 'string' raw python code not supported in jinja2 template syntax. {% if re.search(r"error", l) %} replace line with {% if "error" in l %} can fix problem. if logical condition more complicated, should consider defining own custom filters (which can call python code) or complicated things in view layer. go check global namespace .

i have struct struct control_data{ int column_number; qstring cell; }; i need send thread of qsharememory. read can't because qstring contains pointers inside. other ways? you have serialize struct byte array. can convert qstring const char* this: mystring.tostdstring().c_str(); but serializing qstring should work. the first step serialize struct qdatastream using qt, example here . then once struct can read , written can pass shared memory. a complete example of using qsharedmemory can found here . here relevant code: // first, test whether shared memory segment attached process. // if so, detach if (sharedmem.isattached()) { sharedmem.detach(); } ... qbuffer buffer; buffer.open( qbuffer::readwrite ); qdatastream out( &buffer ); out << youstruct; int size = buffer.size(); // size of int + size of qstring in bytes if ( !sharedmem.create( size ) ) { return; } // write shared memory sharedmem.lock(); char *to = (char*...
