# Template Debugging
|
|
|
|
Here are some snippets you can add to your template to answer some common questions.
|
|
These snippets use the `printf` function available in all Go templates. This function is
|
|
an alias to the Go function, [fmt.Printf](http://golang.org/pkg/fmt/).
|
|
|
|
|
|
### What variables are available in this context?
|
|
|
|
You can use the template syntax, `$.`, to get the top-level template context
|
|
from anywhere in your template. This will print out all the values under, `.Site`.
|
|
|
|
{{ printf "%#v" $.Site }}
|
|
|
|
This will print out the value of `.Permalink`:
|
|
|
|
{{ printf "%#v" .Permalink }}
|
|
|
|
This will print out a list of all the variables scoped to the current context
|
|
(a.k.a. The dot, "`.`").
|
|
|
|
{{ printf "%#v" . }}
|
|
|
|
When writing a [Homepage](/templates/homepage), what does one of the pages
|
|
you're looping through look like?
|
|
|
|
```
|
|
{{ range .Data.Pages }}
|
|
{{/* The context, ".", is now a Page */}}
|
|
{{ printf "%#v" . }}
|
|
{{ end }}
|
|
```
|
|
|
|
### Why do I have no variables defined?
|
|
|
|
Check that you are passing variables in the `partial` function. For example
|
|
|
|
```
|
|
{{ partial "header" }}
|
|
```
|
|
|
|
will render the header partial, but the header partial will not have access to any variables. You need to pass variables explicitly. For example:
|
|
|
|
```
|
|
{{ partial "header" . }}
|
|
```
