so: understand following: templates belong theme. css belongs theme. css , html belong theme. the layout 'above' in way blocks dynamically generated content (content stored in database) , edited through layout editor , assigned specific location in layout. there built-in blocks available pull out specific data. blocks kind of component or widget. i've seen in layout 1 can specify controller , view (presumably dispatcher). so; example; dispatch: viewproduct products.view i'm guessing means layout in loaded theme products view template? in template /templates/views/products/view.tpl find 2 pieces of interest: i. {hook name="products:layout_content"} ii. a comment: "one of selected product templates connected, depending on 'product details view' setting" my questions are: what hook line doing here? and what/where product details view' setting? thanks

please check code below: my %hash = ( 123 => "a", 456 => "b", ); use constant x_1 => 123; use constant x_2 => 456; i want use $hash{x_1} "a". tried store x_1 variable , use key, worked. my $var = "x_1"; # or $var = x_1 but when variable x_1 array store variable, , try access hash variable, shows error. my @arr; $arr[0]{"y_1"} = "x_1"; $arr[0]{"z_1"} = "x_2"; $newvar = $arr[0]{"y_1"};#$newvar = x_1 print $hash{$newvar}; #this shows error. how use variable not string constant here? i want use $hash{x_1} "a" by using identifier, expression won't autoquoted. example, use of following: $hash{+constant} $hash{(constant)} so use $hash{+x_1} instead of $hash{x_1} . how use variable not string constant here? you rightfully ask prevented doing adding use strict; because it's dangerous (meaning hard read, hard debug, hard ma

we know can inject custom message converter: @bean messageconverter messageconverter(){ return new custommessageconverter(); } however in case of errorhandler doesn't work. why ? can conclude code in way ? that's true. spring boot's rabbitannotationdrivenconfiguration doesn't support injection. you have declare own simplerabbitlistenercontainerfactory @bean , supply desired errorhandler injection, other required options, including messageconverter . note overriding out-of-the-box bean should specify own 1 rabbitlistenercontainerfactory name meet condition: @bean @conditionalonmissingbean(name = "rabbitlistenercontainerfactory") public simplerabbitlistenercontainerfactory rabbitlistenercontainerfactory(

say have following list of full scientific names of plant species inside dataset: fullspeciesnames <- c("aronia melanocarpa (michx.) elliott", "cotoneaster divaricatus rehder & e. h. wilson","rosa canina l.","ranunculus montanus willd.") i want obtain list of simplified names, i.e first 2 elements of given name, namely: simplespeciesnames<- c("aronia melanocarpa", "cotoneaster divaricatus", "rosa canina", "ranunculus montanus") how can done in r? we can use sub match word ( \\w+ ) followed 1 or more white space ( \\s+ ) followed word , space, capture group, , rest of characters ( .* ). in replacement, use backreference of captured group ( \\1 ) trimws(sub("^((\\w+\\s+){2}).*", "\\1", fullspeciesnames))

i'm working on ticketing system, staff can send email customers using smtp , when customer replies fetch using imap , add ticket. right i'm adding ticketid in subject line,so when email comes in can append existing ticket. but @ times customers remove subject line , reply creates new ticket. can advice me how around it. think zendesk appends ticketid in email address, not sure if work. most systems have comment in replies telling customer not edit subject line. if remove subject, can instead search email content (if included previous reply information of subject line) perhaps first 200 lines if want limit it, using regular expression pattern match subject line text string , extract ticket number that.

this question has answer here: overloading operator=() callback 1 answer i have class saves big numbers string , can general mathematical operations on it. 1 of these operations assigning int (0-9) 1 digit of big number. question how can overload operators , convert int value char* , save instead of digit in string. following code should work: \\ bignumber[3] == '8' bignumber[3] = 4 \\ bignumber[3] == '4' you can convert string int number; std::ostringstream stream_string; stream_string << number; string numberstring = stream_string.str(); if want convert string char* bignumber[0] = numberstring.c_str();
