Other Information

According to https://github.com/paularmstrong/swig/

swig template engine is no longer maintained, we should consider switching to another template engine.

ejs seemed has similar syntax and is going to stick around for a while, I propose to use ejs as a replacement.

Yeah, i know it. But it's hardly and need very big time to refactoring from swig to ejs and at most cases swig for now work fine. And there is one thing anyway: hexo also use swig as default template and as i know they not want for now to migrate to any another.
If u can and want, u may do it in separated test branch. Or anyone? Who want to do it, please, welcome!

@ivan-nginx Recently I found nunjucks's syntax is similiar to swig, if we have plan to migrate in future, I think nunjuck is a better choice than ejs. XD

[ivan-nginx]

There are many rendering engines, not only ejs, jade or swig. For example, mustache have similar syntax too. But i don't know why we must use mainstream rendering. Swig is work fine and no have any critical bugs. And remake rendering engine will make some special troubles and additional bugs in future.

Anyway, if there will be strong arguments about replace template engine, we can try to implement it. But question is still open: who will do it? It will take a lot of time and i'm not sure what anybody will do it for free.

P.S. If anybody want to use ejs, he can use any other a lot of themes like yilia, material or tranquilpeak. But, ahah, u see this syntax? How about me, a don't like <%- and %>, this so ugly looks and bad for main vision. Look on TQ layout, for example. And look on NexT layout. See the difference?

Already replaced swig by swig-templates in this pull and released in Hexo v3.5.0 and tested with NexT v6.
