In a Go template, sometimes the way to pass the right data to the right template feels awkward to me. Calling a template with a pipeline parameter looks like calling a function with only one parameter.
Let's say I have a site for Gophers about Gophers. It has a home page main template, and a utility template to print a list of Gophers.
http://play.golang.org/p/Jivy_WPh16
Output :
*The great GopherBook* (logged in as Dewey)
[Most popular]
>> Huey
>> Dewey
>> Louie
[Most active]
>> Huey
>> Louie
[Most recent]
>> Louie
Now I want to add a bit of context in the subtemplate : format the name "Dewey" differently inside the list because it's the name of the currently logged user. But I can't pass the name directly because there is only one possible "dot" argument pipeline! What can I do?
- Obviously I can copy-paste the subtemplate code into the main template (I don't want to because it drops all the interest of having a subtemplate).
- Or I can juggle with some kind of global variables with accessors (I don't want to either).
- Or I can create a new specific struct type for each template parameter list (not great).
