Hi @tkliuxing, thanks for the extensive work!!

I will have a look at it after releasing 0.0.24 on Tuesday. We have been cleaning up migrations to start a blank sheet from 0.1. The idea of templates could be on the roadmap for 0.1, but I feel sort of that it would be better to discuss things before implementing them :)

Regarding the idea of templates...

Can the template itself refer to other plugins? And if not, should it? Can it refer to other templates? Is what we are doing actually not just to embed another article, but parametrize the contents of the article?

Let me know what you think, and if you follow what I mean.

On a more practical level...

I know that tests are lacking in many departments. But in order to ensure that your work is well-maintained, would you care to write a couple of basic tests? They can be in wiki.plugins.template.tests.

I see that there are already 3 migrations... I can ensure that the migrations are squashed and included for both South and django.db.migrations.

1. The template itself can refer to other plugins.
2. The template can embed another article.
3. Template parameter means I can define one template like "color":

    {: style="color:{{{0}}}"}

use it to everywhere:

    ### Someone{{color|blue}}
    #### Someone{{color|#ff00aa}}

This markdown extension inherit from markdown.preprocessors.Preprocessor, it means template content will embed to origin markdown text.

About tests and migrations, this is what I do next job.

Known Issues:
A template updated but article no change, cause I forget clear the article cache...
But I can fixed it at next PR :D

PS: My native language is Chinese, I can't use English freely. I'm so sorry about that.
