One way around this limitation is to enable the “do” expression-statement extension and use an array instead of boolean: {% set exists = [] %} {% for i in range(5) %} {% if True %} {% do exists.append(1) %} {% endif %} {% endfor %} {% if exists %} <!– exists is true –> {% … Read more

In the old JSP days, it was very common to have JSP files sprinkled with Java code, which made refactoring much harder, since you had your code scattered. If you prevent logic in templates by design (like mustache does), you will be obliged … Read more
Technically, because context is not passed as a named dictionary, a little work is required to generate a list of the context variables from inside a template. It is possible though. Define a Jinja context function to return the jinja2.Context object, which is essentially a dictionary of the global variables/functions Make that function available in … Read more

The call itself would then look like that: {{template “userlist” dict “Users” .MostPopular “Current” .CurrentUser}} The code for the little “dict” helper, including registering it as a template func is here: var tmpl = … Read more
You can also use envsubst when deploying. e.g. cat app/deployment.yaml | envsubst | kubectl apply … It will replace all variables in the file with their values. We are successfully using this approach on our CI when deploying to multiple environments, also to inject the CI_TAG etc into the deployments.

Neither GCC nor Clang is a linker, and ICF needs to be done by the linker, or at least with cooperation with the linker. Edit: They don’t do ICF, so yes, distinct instantiations produce distinct code. The GNU gold linker supports ICF with the –icf option, which needs the GCC option -ffunction-sections to be used. … Read more
Here is a complete implementation: <test-element obj='{“a”: 1, “b”: 2, “c”: 3}’></test-element> <dom-module id=”test-element”> <template> <template is=”dom-repeat” items=”{{_toArray(obj)}}”> name: <span>{{item.name}}</span> <br> value: <span>{{item.value}}</span> <br> <hr> </template> </template> <script> Polymer({ properties: { obj: Object }, _toArray: function(obj) { return Object.keys(obj).map(function(key) { return { name: key, value: obj[key] }; }); } }); </script> </dom-module>
