Subroutines are created by using the keyword sub followed by an identifier and a code block enclosed in braces.
You can access the arguments by using the special variable @_, which contains all arguments as an array.
sub function_name {
my ($arg1, $arg2, @more_args) = @_;

Basic table usage includes accessing and assigning table elements, adding table content, and removing table content. These examples assume you know how to create tables.
Accessing Elements
Given the following table,

You can pass data to a template in a custom variable.
In your views.py:
from django.views.generic import TemplateView
from MyProject.myapp.models import Item
class ItemView(TemplateView):
template_name = "item.html"
def items(self):

Once you have a Dockerfile, you can build an image from it using docker build.
The basic form of this command is:
docker build -t image-name path
If your Dockerfile isn't named Dockerfile, you can use the -f flag to give the name of the Dockerfile to build.
docker build -t image-name -f Dockerfi...
You can embed another template body into your template via {{template "mysharedtemplate" .}} to reuse shared components. Here is an example that creates a header template that can be reused at the top of all other template bodies. It also uses CSS to stylize the output so that it is easier...
Using .Graph will filter the results to only include those that match the tagset for the alert. For instance an alert for os.low.memory{host=ny-web01} would only include series with the host=ny-web01 tags. If multiple series match then only the first matching result will be used.
template graph.tem...
Using .GraphAll will include all the results in the graph.
template graph.template {
subject = ...
body = `{{template "header" .}}
<strong>GraphAll</strong>
<div>{{.GraphAll .Alert.Vars.graph}}</div>

If you want to graph two series on one graph, you can use the Merge function. This can also be combined with the Series function to manipulate the Y axis (like forcing it to start at zero).
template graph.template {
subject = ...
body = `{{template "header" .}}

This uses the Dropbox Java SDK to create a shared link for a file at the Dropbox path /test.txt:
try {
SharedLinkMetadata sharedLinkMetadata = client.sharing().createSharedLinkWithSettings("/test.txt");
System.out.println(sharedLinkMetadata.getUrl());
} catch (CreateSharedLinkW...
This example uses the Dropbox .NET library to get a shared link for a file, either by creating a new one, or retrieving an existing one:
SharedLinkMetadata sharedLinkMetadata;
try {
sharedLinkMetadata = await this.client.Sharing.CreateSharedLinkWithSettingsAsync (path);
} catch (ApiException...
