javascript - Extracting arguments using regular expressions -

-

i'm trying use regex extract arguments function definition array. example

func(a) -> ['a'] func(a,b) -> ['a','b'] func(a, b) -> ['a','b']

the regex below correctly matches arguments block

/\((?:(\w+),?\s*)+\)/

however, last matched capturing group returned i.e. results are:

func(a) -> ['a'] func(a,b) -> ['b'] func(a,b,c) -> ['c']

this seems useful pattern capturing part of repeating unit. there way correctly achieve expected result?

my saved regexr session can found here

the regex /\((\w+(?:,\s?\w+)?)\)/ return a, b func(a, b), a,b,c func(a,b,c)

hopefully wanted, depending on language you're doing for, can split them each , put them array indexing later.

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 .

Qt4: how to send QString inside a struct via QSharedMemory -

-
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*...
