fix(#135): filter was executed before it was loaded

[ewfian]

The filter won't be work after upgrade to v6.0.0

The hexo loadScripts after loadModules

When this plugin being required and loaded by loadModules, the Renderer constructed and the filter markdown-it:renderer was executed at this time.

hexo-renderer-markdown-it/lib/renderer.js

Line 47 in 4d4d4bd

hexo.execFilterSync('markdown-it:renderer', this.parser, { context: this });

But the script that contains implementation of filter was loaded by loadScripts. So that, the filter has no chance to run.

I had checked how this mechanisms be implemented in another similar plugin hexo-renderer-marked. and the code in v5.0.0

I found that the filter should be executed when each render processed.

BTW: The hexo-renderer-marked execFilter in render process.

BTW2: Another way to fix this issue:
Wrap the execFilter with before_post_render

hexo.extend.filter.register('before_post_render', () => {
    hexo.execFilterSync('markdown-it:renderer', this.parser, { context: this });
});
