javascript - what is the use of data-dojo-config in Dojo -

-

i started learning dojo , came across how include dojo using cdn below code defined in dojo tutorial

<script src="//ajax.googleapis.com/ajax/libs/dojo/1.10.4/dojo/dojo.js"             data-dojo-config="async: true">

here why have missed http? intentional, program not working unless add http in code.

also use of data-dojo-config attribute, don't see difference in basic program if remove attribute. when need use attribute?

when access other examples, see differently:

data-dojo-config="isdebug: 1, async: 1, parseonload: 1"

what these properties, when use them?

he data-dojo-config configurations paramenter the dojo loader , parser. similar configurations parameters set loading database server instance.

what dojo loader , parser?

dojo loader: loads javascript modules ( javascript files ) synchronously or asynchronously.

dojo parser: function of dojo parser parse , convert html code dojo widgets wherever necessary.

the data-dojo-config can set @ start of dojo application.

they cannot changed during run time.

if not set take default values.
can set 1 (or true) or 0 (or false)

isdebug - sets debug level dojo application.
async - (default 1) whether dojo javascript modules should loaded synchronously or asynchronously.
parseonload - when set true dojo parser automatically parses html document , converts data-dojo-elements dojo widgets. if set false need explicitly call dojo parser parse html document.

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*...

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 .
